ATS-N/UA 0000310607-26-000009 LIVE 0000310607 XXXXXXXX 013-00105 false false CBX This filing is an updating amendment to material amendment 0000310607-26-000009, filed April 10, 2026. The material amendment adds functionality that will enable Subscribers within a MOC Hosted Pool to prevent orders from executing against each other on an order-by-order basis, with the addition of a custom FIX tag. This filing amends Part III Item 11(c) to remove the term Trading ID when referring to Subscribers, and add that the custom FIX tag may be used to avoid crosses between accounts, e.g., accounts with the same beneficial owner. An amendment to Part III Item 14(a) redefines Self-Crossing Prevention to include self-crossing and crossing with affiliates. The changes herein apply to all Subscribers and the Broker-Dealer operator. Y INSTINET, LLC 008-23669 000007897 Financial Industry Regulatory Authority 01/14/1980 ICBX https://www.instinet.com Equinix Data Center NY4 755 Secaucus Road Secaucus 07094 US-NJ CoreSite NY2 New Jersey Data Center 2 Emerson Lane Secaucus 07094 US-NJ true true Instinet, LLC ("ILLC") owns and operates the ATS. ILLC's brokerage business takes place on a single trading desk. The component groups of ILLC's trading desk that may enter or direct the entry of orders and trading interest into the ATS are: (1) Execution Trading; (2) High Touch Sales Trading; (3) Electronic Sales Trading; (4) Program Sales Trading; (5) Latency Sensitive Electronic Trading; (6) Event Driven Trading; and (8) Derivatives (Options) and Broker Dealer Execution. Component groups of the ILLC trading desk may submit trading interest to the ATS s in an agency capacity only. The ILLC trading specialist groups primarily utilize the INCA MPID. As noted in Item 22, Clearance and Settlement, in a few circumstances, ILLC gives up trades in real time to a client's clearing broker to settle the transactions, in those circumstances, the trading specialist groups utilize MPIDs INCV, INAB and INCX for client settlement purposes. The ATS consists of four independent crossing sessions: the Main Crossing Session (the "Main Session"), the Conditional Crossing Session (the "Conditional Session"), the VWAP Crossing Session, and the MOC Crossing Session (collectively, the "Crossing Sessions"). Regular trading occurs in the Main Session from 4:00 a.m. until 8:00 p.m. Trading occurs in the Conditional Session from 9:30 a.m. until 4:00 p.m. The VWAP Crossing Session occurs at 9:00 a.m. (the "VWAP Cross"). The MOC Crossing Session (the "MOC Crosses") consists of three (3) different crosses: a cross for securities where the primary listing exchange is the NASDAQ Stock Market ("NASDAQ Cross"), a cross for securities where the primary listing exchange is the NYSE Arca ("Arca Cross"), and a cross for securities where the primary listing exchange is the New York Stock Exchange ("NYSE Cross").] Subscribers and the Broker-Dealer Operator may transmit trading interest to one or more of the Crossing Sessions, which are described in greater detail in Part III, Items 7 and 11. Y N N Instinet Incorporated ("Instinet") operates through locally registered brokerage entities worldwide. "Instinet-branded" affiliates outside of the United States (collectively, the "Instinet BD Affiliates") send their clients' orders in U.S. symbols to ILLC for execution. Orders sent by the Instinet BD Affiliates to ILLC may be routed to, and receive executions in the ATS. ILLC utilizes the INCA MPID, with the exceptions noted above. The Instinet BD Affiliates do not have their own MPIDs. Affiliates that have had orders executed in the ATS since the effective date of the initial Form ATS-N: Instinet Australia PTY Limited - broker-dealer, agency, no MPID Instinet Canada Limited - broker-dealer, agency, no MPID Instinet Europe Limited - broker-dealer, agency, no MPID Instinet Pacific Limited - broker-dealer, agency, no MPID Instinet Singapore Services Private Limited, broker-dealer, agency, no MPID Instinet Germany GmbH - broker-dealer, agency, no MPID Nomura Securities International, Inc. ("NSI") is a U.S. entity engaged in investment advisory and broker-dealer activities, and is a client of ILLC. NSI places orders with ILLC that may be routed to the ATS for execution. NSI acts in a principal and agency capacity and its MPID is NMRA. Additional affiliates within the Nomura financial services group (the "Nomura Group Affiliates") may place orders with NSI or another entity that has a client relationship with ILLC. Such orders may be routed to ILLC for further handling and may subsequently be routed to, and receive executions in, the ATS. The Nomura Group Affiliates may act in a principal or agency capacity. Affiliates that have had orders executed in the ATS since the effective date of the initial Form ATS-N, in addition to NSI, are: Nomura Bank (Switzerland) LTD - broker-dealer and investment adviser, principal and agency, no MPID Nomura International Plc - broker-dealer and investment adviser, principal and agency, no MPID Nomura Securities CO., LTD - broker-dealer and investment adviser, principal and agency, no MPID The Broker-Dealer Operator will update this list as necessary to (1) add any Affiliate that newly executes orders in the ATS, and (2) remove any entity that ceases to be an Affiliate of the Broker-Dealer Operator. Please note the above does not represent an exhaustive listing of all Affiliates that have the ability to enter or direct the entry of orders and trading interest into the ATS. The Broker-Dealer Operator may enter interest in an agency capacity only. N N N N N BACKGROUND: For purposes of this Form ATS-N, Subscribers to the ATS will, where necessary, be termed Direct or Indirect Subscribers. Direct Subscribers are ILLC clients that have been approved to direct their orders to one or more of the ATS Crossing Sessions via FIX (i.e., Subscribers who have elected not to utilize the electronic trading products offered by ILLC to route their orders or trading interest to the ATS) as discussed in Part III, Item 5(a) of this form. Indirect Subscribers are ILLC clients that have been approved to use one or more of the Instinet order and execution management systems ("Instinet OMSs"), the Instinet Execution suite of algorithms ("Instinet Algorithms"), or the Instinet Smart Order Router ("SOR"), all of which may route Indirect Subscriber orders to the ATS based on routing determinations made by the relevant product. Indirect Subscriber orders handled by the Instinet Algorithms, the SOR, or an ILLC trader may be routed to one or more of the ATS Crossing Sessions depending on marketability and the Indirect Subscriber's order handling instructions. Direct and Indirect Subscribers are collectively referred to as "Subscribers." Clients may be both Direct and Indirect Subscribers, depending on the method in which the Subscriber utilized to access the ATS. The use of the Instinet Algorithms and SOR services to enter orders into the ATS or a specific Crossing Session is discussed in Part III, Item 5(a). Additionally, ILLC offers its clients order routing and execution support services through the component groups of ILLC's trading desk listed in Part II, Item 1. The Instinet Algorithms, SOR, Instinet OMSs, and the Front End are referred to herein as the "Instinet Trading Products." ILLC offers these products and services to all Subscribers. Use of these products and services is governed by ILLC's client agreement (the "Client Agreement"), which contains no specific terms and conditions for routing orders into the ATS. The terms and conditions of the Client Agreement do not differ dependent on whether the Subscriber is a Direct or Indirect Subscriber. Orders entering a Crossing Session by any of the products or services listed above will be prioritized, matched, and executed in accordance that Crossing Session's standard matching and execution logic. ILLC offers Indirect Subscribers the ability to enter orders into the ATS by utilizing one or more of the following Instinet Trading Products: ILLC PRODUCTS AND SERVICES: SMART ORDER ROUTER: The SOR is a customizable tool that explores liquidity in various market centers. Clients may elect to utilize the standard SOR configuration to access various market centers (ILLC determines the venues and the order in which client order flow is routed). Clients may also elect to customize the SOR in which case the client may choose the specific venue(s) to which their order flow is routed as well as select the sequence in which their order flow is routed to each venue. The SOR will include all Crossing Sessions as potential venues, provided the client has not elected to limit its strategy to exclude all or a specific subset of Crossing Sessions. Subscribers may also customize the SOR to access only a specific Crossing Session. Users of the SOR must be on-boarded as ILLC clients with access to the SOR. Use of the SOR is governed by the Client Agreement, which contains no specific terms and conditions for routing orders to the ATS. Orders routed to a Crossing Session by the SOR will be prioritized, matched, and executed in accordance with that Crossing Session's standard prioritization, matching and execution logic. INSTINET ALGORITHMS: The Instinet Algorithms include a number of strategies designed to achieve a client's selected trading strategy. Orders routed via the Instinet Algorithms may include all or a specific subset of the Crossing Sessions as possible destinations. Clients may customize the operation of the Instinet Algorithms, including limiting the venues accessed (to the extent permitted by regulatory requirements). Trading interest sent to a Crossing Session by an Instinet Algorithm is subject to that Crossing Session's standard prioritization, matching and execution logic. Unless a client has elected otherwise, trading interest entered into to a Crossing Session by an Instinet Algorithm is treated as representing ILLC's trading interest (i.e., broker-dealer agency trading interest) and not the trading interest of the underlying Subscriber. Users of the Instinet Algorithms must be on-boarded as ILLC clients with access to the Instinet Algorithms. Use of the Instinet Algorithms is governed by the Client Agreement, which contains no specific terms and conditions for routing orders to the ATS. OMS/EMS: ILLC offers the proprietary order/execution management systems Newport and Trading Portal (collectively, the "Instinet OMSs"). The Instinet OMSs allow users to access the ATS in the following ways: (i) by directing trading interest to a specific Crossing Session (other than the Conditional Session) via FIX, (ii) by utilizing an Instinet Algorithm (to the extent offered by the Instinet OMS and permissioned to access one or more Crossing Sessions,) and (iii) by otherwise submitting a non-directed order to ILLC for further handling by trading desk personnel or by entering the order in the SOR. Each Instinet OMS allows users to limit accessible trading venues. In the event an order, or a portion of an order, reaches a Crossing Session via an Instinet OMS, the order is subject to the standard prioritization, matching and execution procedures described herein. Users of an Instinet OMS must be on-boarded as ILLC clients with access to an Instinet OMS. Use of the Instinet OMSs is governed by the Client Agreement, which contains no specific terms and conditions for the management of orders ultimately routed to the ATS, and do not differ based on which OMS is utilized. FRONT END: ILLC owns and operates a front end system (the "Front End"). The Front End is a separate, stand-alone system specific to the BlockCross ATS that includes certain algorithmic and order routing functionality. The Front End allows users to seek contra-side interest for their trading interest outside of the BlockCross ATS while simultaneously allowing for matching and execution within the BlockCross ATS. Only orders entered into the Front End for possible matching and execution within the BlockCross ATS are eligible to access the Front End's algorithmic and order routing functionality. Orders routed from the Front End may include one or more of the Crossing Sessions as a routing destination. The means by which an order reaches a Crossing Session (e.g., Instinet Algorithms, SOR, OMS, FIX) does not affect an order's priority, matching, or execution. Y N BACKGROUND AND SCOPE: Confidential trading information includes data relating to open or partially open orders and recent executions in the ATS and excludes post-execution transaction information of the type made public under reporting rules or regulations, or of an aggregated nature (e.g., aggregated and anonymous order and execution statistics aged at least one day (T+1) from the date of execution). The Broker-Dealer Operator is a wholly owned direct subsidiary of Nomura Holding America Inc. ("NHA") which in turn is wholly owned by Nomura Holdings Inc. ("NHI"). Personnel that provide services to the ATS are employed by NHA or ILLC and certain compliance functions are outsourced to NHI and subsidiaries ("Shared Employees"). Instinet does not have any employees who are solely responsible for the ATS. Listed below are the Shared Employees that service the ATS, ILLC, or an affiliate and have access to confidential trading information. TECHNOLOGY PERSONNEL: Employees that provide information technology ("IT") support, IT development and strategy, tech management, and regulatory reporting services to the ATS (collectively "Technology Personnel"), also provide similar services to (i) ILLC's other business lines and (ii) some other subsidiaries of Instinet, including locally registered brokers Instinet Canada Limited, Instinet Canada Cross Limited, Instinet Europe Limited, Instinet Pacific Limited, Instinet Australia Limited, Instinet Germany GmbH, and Instinet Singapore Limited. For ILLC and Affiliates, Technology Personnel are responsible for the operation, development, monitoring, and testing of various technology systems. For the ATS, certain groups of Technology Personnel are responsible for the operation, development, monitoring, and testing of the ATS's coding, network infrastructure, and software applications. In connection with the performance of their duties, Technology Personnel may access real-time and post-trade Subscriber order and execution information, including orders that were submitted to the ATS but were subsequently cancelled or did not otherwise receive an execution in the ATS. Separately, some Technology Personnel with direct physical access to ILLC servers and databases have the ability to access log files containing ATS order and execution information. Technology Personnel are employed by NHA. OPERATIONS AND COMPLIANCE PERSONNEL: Employees that provide customer support, finance, clearing and middle office support and compliance supervision to the ATS (collectively "Operations Personnel") also provide services to ILLC's other business lines and as needed, certain Instinet BD Affiliates and/or other Nomura Group Affiliates. Customer support personnel are responsible for addressing client inquiries related to connectivity to the ATS and client trading activity and can access real-time and post-trade Subscriber order and execution information in connection with executing their duties. Clearing, middle office support, and Finance are responsible for the clearance, settlement, and billing of transactions and can access post-trade Subscriber order and execution information, including orders that were submitted to the ATS but were subsequently cancelled or did not otherwise receive an execution in the ATS, in connection with executing their duties. Compliance personnel have a range of responsibilities including, but not limited to, responding to regulatory inquiries or performing internal audits of ILLC or its affiliates, including the ATS. Generally, compliance personnel may access post-trade order and execution information, including orders that were submitted to the ATS but were subsequently cancelled or did not otherwise receive an execution in the ATS, in connection with executing their duties but may, when appropriate, be permissioned to access real-time order and execution information. Operations Personnel are employed by NHA. ELECTRONIC TRADING PRODUCTS PERSONNEL: Employees that provide product development, customer support, and product sales support for the Instinet Trading Products (collectively "ETP Personnel") may also provide support to the ATS. Many ILLC clients access the ATS via an Instinet Trading Product. Accordingly, ETP Personnel may provide customer support to Indirect Subscribers as a result of the customer's use of an Instinet Trading Product as a means of access to the ATS. For ILLC, ETP Personnel are responsible for the development, testing, and sales and technology support of the Instinet Trading Products as well as other components of the Instinet systems. For the ATS, ETP Personnel are responsible for the development, testing, and monitoring of the Instinet Trading Products' interaction with the ATS and for compiling data and analytics in response to requests from Subscribers. ETP Personnel may access real-time and post-trade Subscriber order and execution information, including orders that were submitted to the ATS but were subsequently cancelled or did not otherwise receive an execution in the ATS, to support the development, testing, and monitoring of the Instinet Trading Products and to respond to Subscriber requests for data or analytics. ETP Personnel are employed by ILLC or NHA. U.S. LIQUIDITY VENUES TEAM: Employees that provide product strategy, customer support, and sales support for the Instinet ATSs (collectively "Liquidity Venues Personnel") also provide support for other ILLC businesses. For the ATS, Liquidity Venues Personnel provide customer support to Direct Subscribers. For ILLC, Liquidity Venues Personnel develop reports for use by internal groups in monitoring, developing, and enhancing ILLC's products and services. Liquidity Venues Personnel may access real-time and post-trade ATS order and execution information, including orders that were submitted to the ATS but were subsequently cancelled or did not otherwise receive an execution in the ATS, to support each Subscriber's use of the ATS and compile data and analytics in response to requests from Direct Subscribers. U.S. Liquidity Venues Team personnel are emploued by ILLC. SALES AND TRADING PERSONNEL: Trading desk personnel within the component groups identified in Part II, Item 1(a) (collectively, "Sales and Trading Personnel") are responsible for providing order routing and execution support to clients including addressing Subscriber inquiries regarding orders routed to the ATS or other market centers. Sales and Trading Personnel may access real-time and post-trade ATS order and execution information, including orders that were submitted to the ATS but were subsequently cancelled or did not otherwise receive an execution in the ATS, in connection with executing their duties. Sales and Trading Personnel are permissioned for access to such information based on client coverage. The information that may be viewed includes the destination market center for a given order (e.g., the ATS) and whether a previously routed order was executed or cancelled. Sales and Trading Personnel are employed by ILLC. Pursuant to an Assignment of Intellectual Property between ILLC and its direct parent company, Instinet Holdings Incorporated, ("IHI"), IHI licenses to ILLC intellectual property employed by ILLC in connection with the operation of the ATS. Specifically, IHI licenses the ATS matching engine (see Part III Item 11), the functionality used to input and utilize market data (See Part III Item 23), and the systems and infrastructure providing connectivity to the ATS (See Part III Item 6). In addition, IHI develops and licenses certain algorithmic trading products to ILLC (See Part III Item 5). Employees of NHA provide services to the ATS as detailed in Part II Item 6(a) above and Part II Item 7(d) below. As discussed in Part III, Item 22, ILLC utilizes Broadridge Financial Solutions, Inc. systems and services for the purposes of recordkeeping, clearance and trade settlement processing. ILLC utilizes FIS for securities lending, and WORM storage. ILLC utilizes Best Execution and Surveillance Solutions, LLC for regulatory reporting services. The Conditional, MOC and VWAP cross matching engine is hosted in CoreSite NY2 - New Jersey Data Center, in Secaucus NJ, with a back up data center in Rackspace Technology Data Center in Somerset, NJ. The CBX Main Session matching engine is hosted in the Equinix NY4 Data Center in Secaucus, NJ. Pico Quantitative Trading LLC provides hosting services. ILLC consumes the Securities Information Processor feed ("SIP") as discussed in Part III, Item 23. As stated in response to Part II Item 6(a), the Affiliates of ILLC send orders for execution in U.S. markets to ILLC's trading desks, SOR, and algorithmic trading strategies, many of which include the ATS as a destination. Y BACKGROUND AND SCOPE: ILLC's primary system comprises an integrated core messaging system with numerous applications providing, reading, and consuming data messages from the core messaging system (the "ILLC Core"). The Conditional, VWAP and MOC Crosses (e.g., matching engine and associated applications) and ILLC's systems used to support its agency broker-dealer business primarily run on the ILLC Core. The Main Session operates on standalone hardware comprising dedicated servers and software applications (collectively the "CBX Main System", separate from the ILLC Core described above. ILLC maintains policies and procedures designed to safeguard the confidential trading information of the ATS as well as virtual barriers to prevent unauthorized access to such information. The ILLC Core is the conduit through which firm-wide order information is processed (e.g., agency broker-dealer order and execution information and certain ATS order information). Indirect Subscriber order information routed to a Crossing Session via an Instinet Trading Product passes through the ILLC Core. Direct Subscriber orders routed to the Main Session via dedicated FIX connections do not pass through the ILLC Core in route to the ATS. All orders routed to the VWAP and MOC Crosses pass through the ILLC Core. Each application on the ILLC Core subscribes to different message types and is permissioned to subscribe only to the message types necessary for its designated function. For example, the Instinet Trading Products (Instinet Algorithms, SOR, and OMS/EMS) are subscribed to utilize messages regarding the orders routed by the relevant product, including where orders were routed and/or executed, which may include a Crossing Session or any other market center. The CBX Main System provides a real-time, continuous data feed (the "CBX Main System data feed") to the SOR that contains aggregated and anonymized buy and sell information for resting orders in the Main Session. The data feed includes symbol, side (buy or sell), and aggregated quantity. The data feed includes aggregated orders from Direct and Indirect subscribers sent to the Main Session. The feed is used by the SOR solely for the purposes of determining whether to route an order to the Main Session and is not used for any non-routing purposes. Except as described above, the Instinet Trading Products may not access data messages on the ILLC Core related to other ILLC functions, including data messages related to the VWAP and MOC Crosses generally, Direct Subscriber orders, ATS order priority, or counterparty information EMPLOYEES WITH ACCESS TO ATS CONFIDENTIAL TRADING INFORMATION: Instinet does not have any employees solely responsible for the ATS. The employees described in response to Part II, Item 6(a) have access to confidential trading information. These employees are prohibited from sharing any confidential trading information with persons not expressly permissioned to receive such information under Instinet policy, as described in Part II, Item 7(a). Physical access to Instinet's servers and databases is limited to employees responsible for operating the system and is generally further limited to employees performing necessary IT functions. Instinet servers and databases are housed in locked rooms requiring keycard access. Entry and exit are monitored via video surveillance. ILLC reviews and permissions employees for physical access to Instinet's servers and databases in accordance with the policies and procedures outlined in Part II, Item 7(a) (ii) below. SYSTEMS WITH ACCESS TO ATS CONFIDENTIAL TRADING INFORMATION - DIRECT SUBSCRIBER: ILLC Data messages are periodically written to a database for storage and retention (the "Core Database"). This information includes ATS order and execution information from both the CBX Main System and the ILLC Core systems, as well as other ILLC data. Instinet maintains certain support tools, which allow a user to query the Core Database for the purposes of monitoring, reporting, and testing the Instinet systems and applications, including the ATS (the "Support Tools"). Access to the Support Tools is limited to personnel supporting the operations of the CBX Main System and the ILLC Core and related databases and compliance supervisory personnel. Employees responsible for operating the CBX Main System include Operations and Technology Personnel and ETP Personnel whose responsibilities include the operation of the ATS. Members of the Liquidity Venues Team are permissioned to access Subscriber order and execution information. ATS data, including order and execution information, is a subset of the data retained on the Core Database. Personnel whose responsibilities include the operations of the ATS and related systems or its compliance with applicable rules, may be permissioned to access ATS order and execution information via the Support Tools. Other personnel may be permissioned for access to the Support Tools but will be prevented from accessing ATS confidential trading information. ILLC reviews and permissions employees for access to the Support Tools in accordance with the policies and procedures outlined in Part II, Item 7(a)(ii) below. The CBX Main System data feed, as described above, is made available to the SOR. The ATS does not provide client specific information in the data feed to the SOR. The CBX Main System data feed includes aggregated orders from Direct and Indirect subscribers sent to the Main session. The feed is used by the SOR solely for the purposes of routing decisions and is not used for non-routing purposes. The SOR does not share any information within the data feed with any other Instinet systems or third parties, other than personnel who require access to perform maintenance or to address technological, legal or compliance issues that may arise with the ATS or the SOR. SYSTEMS WITH ACCESS TO CONFIDENTIAL TRADING INFORMATION -- INDIRECT SUBSCRIBER: The Newport OMS and Instinet Algorithms (including the SOR) can transmit confidential trading information to the extent orders are managed by the Newport OMS or routed through an Instinet Algorithmics strategy. Data related to Indirect Subscriber orders managed by the Newport OMS or routed through an Instinet Algorithmic strategy is accessible through certain GUIs that can disseminate information regarding the destination market center for a given order (e.g., a Specific Crossing Session) and whether a previously routed order was executed or cancelled. Through the Newport OMS, Technology and ETP Personnel who support the Instinet Algorithms strategies or the OMS utilized may access real-time and post-trade Indirect Subscriber order and execution information routed or managed through the relevant strategy or OMS (Direct Subscriber order and execution information will not pass through an Instinet OMS or the Instinet Algorithms). Sales and Trading Personnel may also be permissioned, based on client coverage, to access real-time and post-trade order and execution via the Newport OMS. Note, certain members of the Electronic Sales Trading component group of the ILLC trading desk are considered client coverage for all clients utilizing the Instinet Algorithms. Note, the information available to such support or trading personnel is provided by systems supporting the relevant strategy or OMS and does not include information regarding an order's priority or status in the ATS or another market center. Information regarding ATS orders and executions that do not relate to the relevant strategy or were not managed by the OMS is not transmitted by these systems. The CBX Main System data feed, as described above, is made available to the SOR for the purposes described above. The ATS does not provide client specific information in the data feed to SOR. The CBX Main System data feed includes aggregated orders from Indirect and Direct subscribers sent to the CBX Main session. The feed is used by the SOR for the purposes of routing decisions and is not used for any non-routing purposes. The SOR does not share any information within the data feed with any other Instinet systems or third parties, other than personnel who require access to perform maintenance or to address technological, legal or compliance issues that may arise with the ATS or the SOR. With respect to orders routed to the Main Session through or by the SOR, the SOR, will have information relating to the identity of the Subscriber submitting the order, as well as the price, side, symbol, order type, and the order attributes described in this Section. CONFIDENTIAL TRADING INFORMATION SAFEGUARDS: ILLC requires permissioned logins to access Instinet Systems. Additionally, Instinet's global cyber security efforts, including measures to detect and prevent unauthorized access to Instinet systems, apply to ILLC and its affiliates, including the operation of the ATS. Relevant Principals and Supervisors must approve employee access to Instinet systems, including the ATS and the applications with the ability to access Subscriber confidential trading information outlined above. SEPARATION: ILLC has implemented physical and virtual information barriers to separate ATS data from other ILLC data and, in turn, separate personnel and systems with access to Subscriber confidential trading information from those not permitted to access such information. ACCESS TO DIRECT SUBSCRIBER INFORMATION: Employees seeking to access the systems that may transmit or disseminate Direct Subscriber Information (see above section titled Systems with Access to Direct Subscriber Confidential Trading Information) must receive approval from the ATS Supervisor. In reviewing such requests, the ATS Supervisor considers factors including the employee's current role and whether the employee performs a function related to the operations of the ATS and related systems or its compliance with applicable rules that requires access to Direct Subscriber information. An employee's request for access may be denied if, based on the ATS Supervisor's review: (1) the employee's stated job function does not relate to the operations of the ATS and related systems or its compliance with applicable rules, (2) the employee has requested a type of permissioning (see below) that is too broad for the employee's stated job function, or (3) the employee can perform their stated duties without such access. If an employee changes roles, the ATS Supervisor will adjust the employee's access to appropriately reflect the employee's new role. Based on this review, the ATS Supervisor or delegate may revoke, suspend, or modify access. Decisions to approve access are subject to a periodic review pursuant to ILLC's Regulation ATS written supervisory procedures ("WSPs") described below. On a monthly basis, the ATS Operations Principal or delegate conducts a review to confirm the appropriateness of user access to Subscriber confidential trading information, including verification that users whose roles have changed and/or, employees who have been inactive, transferred or terminated have their permissioned access modified accordingly. Based on this review, the ATS Supervisor or delegate may revoke, suspend, or modify access. ACCESS TO INDIRECT SUBSCRIBER INFORMATION: Employees seeking to access the systems that may transmit or disseminate Indirect Subscriber information (see above section entitled Systems with Access to Indirect Subscriber Confidential Trading Information) may be permissioned to do so on an as needed basis. ACCESS TO MAIN SESSION DATA FEED - DIRECT AND INDIRECT SUBSCRIBER INFORMATION The Main Session Data Feed is made available to the SOR via an application on the ILLC Core which is permissioned to subscribe to the specific message type. The CBX Core transmits to the ILLC Core details of the order book without client identifying information. Employees seeking to access the Main Session Data Feed must receive approval from the ATS Supervisor, as described above, prior to being enabled for access by the Client On-boarding team. PERSONAL TRADING RESTRICTIONS: Instinet Incorporated maintains an Employee Investment Policy (the "EIP") which covers employees of all U.S. subsidiaries, and includes employees supporting the ATS. The EIP is designed to encourage long-term investments and prohibits employees from engaging in day-trading activities. Instinet prohibits all employees, including those with access to Subscriber Confidential Trading Information, from trading based on non-public, or other confidential information. The EIP requires employees to maintain EIP covered accounts at specified brokers that have agreed to provide Instinet daily trading information for employee personal accounts. EIP covered securities are subject to a 15-day holding period. Prior to entering any trades in a personal account covered by the EIP, employees must enter a trade approval request via the Personal Trading Control Center ("PTCC") tool and receive an approval from both their supervisor and PTCC group. The PTCC tool requires the employee to certify that the employee: (1) is not in possession of any material non-public information concerning the security or commodity the employee proposes to buy or sell; (2) does not know of a pending customer trade nor of a pending research report in the security or commodity; (3) is not engaging in personal trading activity that violates Instinet's policies and procedures, including the Code of Ethics, or any duties owed to Instinet or its clients; (4) has reviewed Instinet's restricted list and the proposed transaction is not on the restricted list; (5) has confirmed that the proposed transaction meets the holding period requirement; (6) agrees that the proposed transaction must be effected on the same day on which approval is given; and (7) has confirmed that the proposed transaction(s) does not involve the purchase of an initial public offering (IPO) or any other type of new equity issue. In approving or denying such a request, supervisors may review the employee's trades for any unusual activity, possible front-running customer trades or research, or conflicts with any of Instinet's businesses. In addition, supervisors consider whether transactions are appropriate, given the employee's economic status and investment experience and whether the transactions are of such a frequency that they may distract the employee from his or her responsibilities at Instinet. Separately, the Compliance Department reviews personal trades daily and consults with managers if irregularities are identified. Generally, if an approval for an employee trade is given, it remains in force for the trading day in which it was received. Once an employee receives written confirmation approving a covered transaction, the employee may enter a trade in that symbol. Employee supervisors review each employee's trading activity on a post trade basis and check for irregularities and potential red flags. In the event any irregularities or red flags are discovered, supervisors are to escalate the matter to Instinet management and the ILLC Chief Compliance Officer. Instinet, in its discretion, may take any action against an employee found to have violated the EIP, up to and including termination. CONFIDENTIAL INFORMATION AND INSIDER TRADING: Instinet Incorporated maintains a policy regarding confidential information and insider trading which covers employees of all U.S. subsidiaries, including employees supporting the ATS. Employees must not disclose any confidential information to anyone who is not authorized by Instinet to receive it pursuant to these policies and may not use such information, other than in the course of their employment and in connection with the performance of the duties for which access to such information has been granted. Accordingly, employees may not use confidential information to: (1) trade securities for their own accounts, accounts in which they have a direct or indirect beneficial interest, or accounts over which they can exercise control; or (2) advise relatives, friends, or other persons about possible securities transactions. Nor may employees authorize anyone else to disclose or use confidential information in a manner that would violate these prohibitions. WRITTEN PROCEDURES: ILLC's Regulation ATS WSPs provide specific guidelines for the initial review and approval process, as well as the ongoing evaluation of, employee access to ATS data. Prior to granting any employee access to Instinet's systems, including the ATS and the applications with the ability to access Subscriber confidential trading information (including the Main Session Data Feed), the ATS Supervisor must review and document each employee's level and type of access requested, the role and responsibilities of the employee, and the purpose for which access was requested. On a monthly basis, employee access is reviewed to determine whether their level of access to Instinet's systems, including the ATS and the applications with the ability to access Subscriber confidential trading information remains appropriate. The ATS Supervisor must document each review and the changes made, if any, to employee access. Periodically, the Internal Audit group reviews the ATS operations generally. Such reviews typically include testing the ATS WSPs, assessing the ATS Supervisor's review of employee access, and confirming that each review has been properly documented. ILLC considers all Subscribers to the ATS to have consented to the disclosure of their confidential trading information as described in Part II, Items 6(a) and 7(a) above and in the following ways. MARKETING: ILLC may include, in marketing materials or client presentations, aggregated and anonymous analysis related to order and execution statistics derived from orders and executions in the ATS. Subscribers do not have the ability to opt out of the use of their related order and execution information for ILLC marketing purposes. CLIENT COVERAGE: ILLC may permission the systems and personnel described in Part II, Items 6(a) and 7(a) to access Subscriber (both Direct and Indirect Subscribers) confidential trading information. Subscribers may request to limit such disclosure, with respect to Sales and Trading Personnel, in accordance with the procedure described in response to Part II, Item 6(c) below. ILLC reserves the right, in its sole discretion, to honor such requests and will review each request on a case-by-case basis. Typically, ILLC will honor such requests by adjusting a client's coverage model to reflect the client's requested opt out. THIRD PARTIES: ILLC does not disseminate Subscriber Confidential Trading Information to third parties, other than those listed in Part II, Item 6(b), except where required by applicable law. Subscribers may request that ILLC share their confidential trading information with third parties at their discretion. Subscribers may request to withdraw their consent to the information described above by contacting their sales representative in writing via email or instant message. Subscribers making such requests will receive written notification regarding their request to opt-out as soon as practicable. ILLC conducts periodic reviews of opt out requests to ensure that such requests have been implemented. The persons described in response to Part II, Item 6(a) and (b) have access to Subscriber confidential trading information. The type of information that such persons can access along with the reasons for such access is described in response to Part II, Item 6(a) and (b). Investment Companies Issuers Brokers Asset Managers Principal Trading Firms Hedge Funds Market Makers Banks Dealers N Only clients of ILLC with accounts approved for trading may be Subscribers of the ATS. Prior to establishing a trading account for a prospective client, ILLC will require (1) the client's name, address and other identifying information, as well as the name of any adviser/agent authorized to trade for the account; (2) the citizenship (or place of incorporation) of the client; (3) a Taxpayer Identification Number or equivalent; (4) the type of client, e.g., registered investment adviser, registered broker-dealer, etc.; (4) the names of the persons designated by the client for trading authorization; (5) clearing instructions, including, where applicable, the identity of the client's prime broker or custodian (ILLC does not custody customer securities); and (6) a completed account application, client agreement and supplementary documentation, as appropriate. ILLC does not admit natural persons as Subscribers to the ATS. Prospective clients must also pass ILLC's AML/KYC/CIP risk assessments, as well as any credit assessments. ILLC reserves the right to prevent or otherwise limit a prospective Subscriber from accessing the ATS if they fail to meet the requirements to become a client, in ILLC's sole discretion. ILLC may prevent or otherwise limit any client's access to the ATS generally, or to a specific Crossing Session. Factors that may be considered in preventing or otherwise limiting a client from accessing the ATS include, but are not limited to, reputational risk to Instinet, failure to make timely and proper settlement of transactions, regulatory actions or findings suggesting inappropriate activity, or a failure to satisfactorily respond to an information request. For purposes of access to the ATS, Subscribers are not required to enter into any specific clearing arrangement. Y Y ILLC may prevent or otherwise limit any Subscriber's access to the ATS if they fail to meet the requirements to become a client or ILLC decides to terminate its relationship with the client based on factors related to the client's activity within the ATS or otherwise. As set forth in the Client Agreement, ILLC may, at any time, without cause or notice, (i) suspend or terminate all or part of the ATS or other Instinet services or a client's access thereto, (ii) change the nature, composition or availability of all or a portion of the Instinet services or (iii) change any limits or restrictions on the trading or other activities a client may conduct through the Instinet services. If a client's passwords or other access methods ("Access Methods") are lost, stolen or compromised, ILLC will cancel or suspend the access methods upon receipt of notice from the client. ILLC may terminate, revoke, suspend, modify or change any or all of a client's Access Methods at any time, without prior notice, in its sole and exclusive discretion. ILLC may, in its sole and absolute discretion, reject any order that exceeds established limits, appears to be entered in error, or is otherwise unacceptable. ILLC may also terminate its relationship with a client, and by extension, prevent or otherwise limit a Subscriber's access to the ATS based on factors including, but not limited to, reputational risk to Instinet, failure to make timely and proper settlement of transactions, regulatory actions or findings suggesting inappropriate activity, or a failure to satisfactorily respond to an information request. For instance, ILLC has terminated client access to ILLC's services due to client failure to adequately address compliance questions relating to the client's trading activity. As noted above, ILLC may, in its sole discretion, exclude a Subscriber from the ATS, or suspend or withdraw access in whole or in part. Any suspension of ILLC, in its capacity as a Subscriber to the ATS, is likely to be temporary, and to arise from a technical issue or another event that presents a risk to the ATS system or another Instinet service. MAIN SESSION HOURS OF OPERATION: Regularly scheduled trading hours in the Main Session are from 4:00 a.m. until 8:00 p.m. Eastern Time. Orders received when the Main Session is not in operation are rejected and open orders, if any, are canceled back. During market holidays or shortened trading days this period of operation will be amended subject to the availability of market data. On market holidays or shortened trading days, once market data is no longer available, the Main Session will not be available. CONDITIONAL SESSION HOURS OF OPERATION: ILLC may submit trading interest and orders on behalf of Indirect Subscribers for matching and execution between 9:30 a.m. and 4:00 p.m. Eastern Time. During market holidays or shortened trading days these periods of operation will be amended. On market holidays or shortened trading days, once market data is no longer available, the Conditional Session will not be available. VWAP AND MOC CROSSES HOURS OF OPERATION: The VWAP Cross occurs at 9:00 a.m. Subscribers may submit orders to ILLC between 7:30 a.m. and 9:00 a.m. for the VWAP Cross. Subscribers may submit orders for the MOC Crosses at any time between 7:30 a.m. and the relevant crossing session's crossing time. During market holidays or shortened trading days these periods of operation will be amended subject to the availability of market data. Y ILLC utilizes the FIX 4.0 and FIX 4.2 protocol for global electronic trading and is FIX compliant with the standard messaging format of the FIX 4.0 and FIX 4.2 protocol version. As discussed below in Item 5(c), ILLC clients may send directed orders to the VWAP and MOC Crosses or the Main Session via a FIX connection. The VWAP, MOC, and Conditional Cross are hosted in the CoreSite Data Center in Secaucus. The Main Session matching engine is hosted in the Equinix NY4 Data Center in Secaucus. Pico Quantitative Trading LLC provides hosting services in Equinix. Orders directed to the Main Session that are entered through CoreSite connections will travel to the matching engine located in Equinix. The ATS itself does not offer cross connections. Direct Subscribers may connect via cross connection when the Subscriber's system is located, or the Subscriber maintains a point of presence, in the same data center used for the matching engine. In the event a Direct Subscriber establishes a cross connection with the ATS, the Subscriber provides, installs and maintains the hardware used for connection. Orders entered into the ATS via a FIX connection do not pass through the Instinet Algorithms or SOR to access the ATS. Y MEANS OF ENTRY GENERALLY: ILLC clients may send directed orders to the VWAP and MOC Crosses or the Main Session via a FIX connection. Subscribers may access each Crossing Session indirectly via the Instinet SOR or a specific Instinet Algorithmic strategy. Subscribers may use an Instinet OMS/EMS to send a directed order to the VWAP and MOC Crosses or the Main Session via FIX, or to access the SOR or Instinet Algorithms. The Conditional Crossing Session may only be accessed indirectly via the Instinet SOR or a specific Instinet Algorithmic strategy. The Instinet router or strategy chosen will determine where individual orders are routed, including to external market centers and ATSs, which may include any Instinet ATS. Once an order reaches a Crossing Session, the means by which the order reached the Crossing Session (e.g. Instinet Algorithm, SOR, OMS, FIX) does not affect the order's priority, matching, or execution. In addition, clients of ILLC may submit orders to ILLC for further handling or routing (See Part II, Item 5), whether via ILLC's trade desk personnel, Instinet Trading Products or otherwise, and ILLC may route such orders to a Crossing Session. Subscribers and the Trading Desks use the same methods to access the Crossing Sessions. Latency is the total amount of time it takes for a message to reach the ATS, be processed by the ATS, and be responded to by the ATS. Latency may differ on an order by order basis due to various conditions. The experienced latency for any individual order may materially differ from the median times typically observed based on these variable conditions. For example, the volume of messages transmitted across a given connection at a specific point in time or the location from which an order is transmitted (e.g., the physical distance from a Subscriber's server or point of presence to the ATS) may impact the latency experienced on an individual order. Additionally, clients may request bespoke configurations to the Instinet Trading Products (e.g., a client requesting a configuration of the SOR where the only venue to which its orders would be routed is the ATS may experience greater latency than a Subscriber choosing to route the same order to the ATS via a direct FIX connection) which may impact the latency experienced for that client's orders. MEANS OF ENTRY - MAIN SESSION: ILLC clients may choose to send directed orders to the Main Session via a FIX connection dedicated to the Main Session, or via a FIX connection that can handle orders to all ATS Crossing Sessions and other Instinet Trading Products. Orders sent via a FIX connection dedicated to the Main Session do not pass through the ILLC Core in route to the Main Session; however, ILLC will reject any orders not directed to the Main Session transmitted via a FIX connection dedicated to the Main Session, including orders directed to the VWAP Cross, the MOC Crosses, or other Instinet Trading Products. Orders directed to the Main Session via a FIX connection that can handle orders to all Crossing Sessions and other Instinet Trading Products do pass through the ILLC Core in route to the Main Session. In the event the Instinet SOR or Instinet Algorithms strategy determines to transmit an order to the Main Session, an electronic message will be sent from the ILLC Core to the CBX Core using the FIX protocol (as described in Part III Item 5(a) above), in the same manner that Subscribers utilizing a FIX connection may transmit orders. MEANS OF ENTRY - VWAP AND MOC CROSSES: ILLC clients may choose to send directed orders to the VWAP or MOC Crosses via a FIX connection. Such orders are directed to the chosen Crossing Session via the ILLC Core and may not be transmitted via a FIX connection dedicated to the Main Session. In the event the Instinet SOR or Instinet Algorithmic strategy chooses to transmit an order to the VWAP or MOC Crosses, an electronic message will be transmitted within the ILLC Core directing the order to the chosen Crossing Session. MEANS OF ENTRY - CONDITIONAL SESSION: ILLC Clients may access the Conditional Session indirectly via the Instinet SOR or a specific Instinet Algorithmic strategy. The Instinet router or strategy chosen will determine where individual orders are routed, including to external market centers and ATSs, which may include any Instinet ATS. The Conditional Session receives order messages from the Instinet SOR or Instinet Algorithms via a proprietary messaging format, and does not support direct FIX connections from subscribers. Y N N N MAIN SESSION ORDER TYPES AND ATTRIBUTES: The Main Session accepts market, limit and pegged order types. "Market" is an order to buy or sell at immediately at the best available price. "Limit" is an order to buy or sell at a specified price or better. "Pegged" is an order to buy or sell at a price relative to a benchmark reference price. The Main Session accepts both "buy" and "sell" orders. All Subscribers may submit orders to sell "long" or "short," but only broker-dealer Subscribers may submit orders marked "short sale exempt." Pegged orders are limit orders pegged to the national best bid ("NBB"), national best offer ("NBO") or midpoint of the national best bid and offer ("NBBO"). Pegged orders may include an ultimate limit price. Orders pegged to the NBB or NBO may include a peg-offset (e.g., Buy 100 shares XYZ pegged at the NBB plus/minus $.02). For orders priced at $1.00 per share or higher, peg-offsets may only be expressed in whole penny amounts. Orders pegged to the midpoint of the NBBO may not include a peg-offset. Orders may be designated immediate-or-cancel ("IOC"), "Day", Fill-or-Kill ("FOK") or "Good Till." While "Good Till" orders types with an expiry longer than a day will be accepted, they will be cancelled back at the end of the day if not executed. Subscribers may indicate a minimum acceptable quantity ("MinQty") associated with an order. The MinQty condition specifies the smallest contra-side order with which the Subscriber is willing to interact. A MinQty value must be satisfied on a single order from a single counterparty basis; the Conditional Session will not aggregate multiple orders to satisfy the MinQty requirement. The Main Session allocates, matches, and executes orders using price/time priority. For derivatively-priced (e.g., pegged) orders, the time of order receipt will be deemed to be the time of each price change. However, where two pegged orders are deemed to be on time parity the ATS will treat the order originally received first as having priority; no two orders can enter the Main Session at exactly the same time. For passive (i.e., nonmarketable) limit orders priced outside the NBBO, the time of order receipt will be deemed to be the time the order most recently became eligible to be executed at or within the NBBO. Limit orders priced through the NBBO and market orders are treated the same as market pegged orders. IOC or Day orders that are deemed to be removing liquidity from the Main Session will receive all available price improvement by default. Upon Subscriber request, ILLC will configure a Hosted Pool within the Conditional Session to split price improvement equally between both sides of an execution for all executions within that pool (see Item 11(c) for information on Hosted Pools and Conditional Session Price Improvement). For two given orders, the order viewed by the Main Session as having been received first will be deemed to be adding liquidity. As noted above, the time of order receipt for any derivatively priced order is deemed to be the time of the most recent reference price change. Main Session does not permit the execution of orders outside the NBBO. Main Session does not permit the execution of orders when the NBBO is locked or crossed. The Main Session does not currently allow order types designed not to remove liquidity (e.g., post-only orders). Orders are not routed out of the Main Session. Up until an order is matched, Subscribers may modify, cancel, replace or remove their orders from the Main Session at their discretion. In the event a Subscriber modifies, cancels or replaces an order in the ATS, the time of order receipt will be updated and the order will be prioritized based on the updated time of receipt. Any malformed order will be rejected. All order types discussed above are available across all forms of connectivity to the ATS. CONDITIONAL SESSION ORDER TYPES AND ATTRIBUTES: The Conditional Session accepts market, limit and pegged order types. ILLC may submit orders on behalf of Indirect Subscribers to sell "long", "short" or "short sale exempt." ILLC may also submit Conditional Orders to the Conditional Session on behalf of Indirect Subscribers. Conditional Orders represent trading interest and are neither firm nor executable. Please see Part III, Item 9 and Part III Item 11 for additional information concerning Conditional Orders. Pegged orders are limit orders pegged to the national best bid ("NBB"), national best offer ("NBO") or midpoint of the national best bid and offer ("NBBO"). Pegged orders may include an ultimate limit price. Orders pegged to the NBB or NBO may include a peg-offset (e.g., Buy 100 shares XYZ pegged at the NBB plus/minus $.02). For orders priced at $1.00 per share or higher, peg-offsets may only be expressed in whole penny amounts. Orders pegged to the midpoint of the NBBO may not include a peg-offset. Orders may be designated immediate-or-cancel ("IOC"), "Day", Fill-or-Kill ("FOK") or "Good Till." While "Good Till" orders types with an expiry longer than a day will be accepted, they will be cancelled back at the end of the day if not executed. Subscribers may indicate a minimum acceptable quantity ("MinQty") associated with an order. The MinQty condition specifies the smallest contra-side order with which the Subscriber is willing to interact. A MinQty value must be satisfied on a single order from a single counterparty basis; the Conditional Session will not aggregate multiple orders to satisfy the MinQty requirement.

IOC or Day orders that are deemed to be removing liquidity from the Conditional Session will receive all available price improvement by default. Upon subscriber request, ILLC will configure a Hosted Pool within the Conditional Session to split price improvement equally between both sides of an execution for all executions within that pool. (see Item 11(c) for information on Hosted Pools and Conditional Session Price Improvement).For two given orders, the order viewed by the Conditional Session as having been received first will be deemed to be adding liquidity. As noted above, the time of order receipt for any derivatively priced order is deemed to be the time of the most recent reference price change.

Up until an order is matched, Subscribers may modify, cancel, replace or remove their orders from the Conditional Session at their discretion. In the event a Subscriber modifies, cancels or replaces an order in the ATS, the time of order receipt will be updated and the order will be prioritized based on the updated time of receipt. The Conditional Session order types discussed above are only available via the Instinet SOR or a by utilizing an Instinet Algorithm strategy. The Instinet router or strategy chosen will determine where individual orders are routed, including to external market centers and ATSs, which may include any Instinet ATS. The Conditional Session does not support orders transmitted via direct FIX connections from subscribers. ROUTABILITY (ALL CROSSING SESSIONS): Orders are not routed out of the Main Session, the Conditional Session, the VWAP Cross, or MOC Crosses. Orders are not routed between Crossing Sessions within the ATS. VWAP AND MOC CROSSES (GENERALLY): The VWAP and MOC Crosses are point-in-time crosses that accept both "buy" and "sell" orders. All Subscribers may submit orders to the VWAP and MOC Crosses to sell "long" or "short," but only broker-dealer Subscribers may submit orders marked "short sale exempt." The VWAP Cross only accepts VWAP orders (i.e., Subscribers send orders to the VWAP Cross without a set limit price which, upon receiving a match for a given order, will receive an indicative fill priced at the midpoint of the symbol's NBBO). The MOC Crosses only accept market-on-close orders. The VWAP and MOC Crosses only accept orders with a time-in-force instruction of "day." Until the cross occurs, Subscribers may modify, cancel, replace or remove their orders from the VWAP or MOC Crosses at their discretion. Once the match has occurred, unmatched orders will be cancelled back to Subscribers. Subscribers may indicate a minimum acceptable quantity ("MinQty") associated with an order entered into the VWAP and MOC Crosses. A MinQty condition must be entered in one or more round lots. A MinQty value is not required to be satisfied on a single order from a single counterparty basis. Multiple orders will be aggregated to satisfy a MinQty requirement. VWAP CROSS ORDER TYPES AND ATTRIBUTES: Orders entered into the VWAP Cross are matched on a pro rata basis. Subscribers may elect to receive preliminary reports after the VWAP Cross indicating the number of shares that matched in the cross. Unmatched orders will be cancelled back if not matched in the VWAP Cross. After the close of the primary trading session in the relevant U.S. market, the volume-weighted average price is calculated and Subscribers receive a report indicating the price at which their orders have been executed. ILLC calculates the execution price of VWAP transactions on the basis of the trading that takes place in the security during regular trading hours on the same day that the match occurs, including opening auctions and closing auctions. (See discussion in this Part III, Item 7 under the heading VWAP Calculation for additional detail). Subscribers may indicate either a "Buy Cash Constraint" or a "Sell Cash Constraint" (together, the "Cash Constraints") associated with an order or group of orders entered into the VWAP Cross. A "Buy Cash Constraint" indicates the maximum net notional value that the Subscriber is willing to purchase across an order or group of orders. A "Sell Cash Constraint," indicates the maximum net notional value that the Subscriber is willing to sell across an order or group of orders. Where a Cash Constraint would be exceeded the ATS will execute the Subscriber's orders on the relevant side of the market on a pro rata basis based on each order's absolute notional value. The Cash Constraint applied at the time of the match is based on the previous night's closing price. VWAP CALCULATION: ILLC calculates the execution prices of VWAP Cross transactions by using price, quantity, and sale condition data from trades disseminated by the SIP (i.e., the Consolidated Tape System ("CTS") for Tape A and B securities and the Unlisted Trading Privileges ("UTP") Plan for Tape C securities). Sale condition data is used to determine whether a transaction is eligible or ineligible for inclusion in Instinet's VWAP price calculations. Price and quantity information are used to calculate the ultimate VWAP Cross execution prices. SIP trades with the following sale conditions are excluded from the calculation: Average Price Trade; Cash Trade (same day settlement); Market Center Official Close; Next Day Trade (next day settlement); Market Center Official Open; Seller's Option (irregular settlement); Extended Hours Trade; Extended Hours Sold (out of sequence); Contingent Trade; Derivatively Priced; Qualified Contingent Trade; and Corrected Consolidated Close Price as per Listing Market (collectively "Sale Conditions"). Odd lot trades are eligible for inclusion in ILLC's VWAP price calculations absent one of the above listed Sale Conditions. For each security receiving an indicative fill in the VWAP Cross, ILLC calculates the VWAP execution price in the following manner: the notional values (price*quantity) of each eligible transaction for a security are added to determine the security's total notional value executed during the trading day ("TNV"). The share quantities of each eligible transaction are added to determine the security's total shares traded ("TST"). The execution price for each security receiving an indicative fill in the VWAP Cross is equal to the security's TNV divided by the security's TST. Trading halts or pauses do not impact the calculation of the VWAP execution prices. MOC CROSSES ORDER TYPES AND ATTRIBUTES: The MOC Crosses matches buy and sell orders marked "market on-close." The MOC Crosses consists of three (3) different crossing sessions: a NASDAQ Cross, an ARCA Cross, and a NYSE Cross. The MOC Cross system will first attempt to match orders entered by the same Subscriber into a MOC Cross (i.e. Subscriber priority), with any open order being matched on a pro rata size basis against any other Subscriber with an open order in the MOC Cross. Unmatched interest following the MOC Crosses is cancelled back to the Subscriber or SOR, as applicable. Subscribers may elect to receive preliminary execution reports indicating the number of shares that have matched on a security-by-security basis or for all orders submitted to the MOC Crosses. The execution price of all orders matched in a MOC Crosses is the security's closing auction price on the security's primary listing exchange or, where a closing auction does not occur, the last closing price disseminated by the primary listing exchange, if any. Only broker-dealer Subscribers may submit orders as short-sell exempt. MAIN AND CONDITIONAL SESSION SIZE REQUIREMENTS: The Main Session and Conditional Session have a minimum order quantity of one share. Any order greater than 1,000,000 shares, or that otherwise exceeds pre-set financial and regulatory risk management controls will be rejected. VWAP AND MOC CROSSES SIZE REQUIREMENTS: The VWAP and MOC Crosses will accept orders of any size; however, for the VWAP Cross, orders must be greater than or equal to one round lot to be eligible to cross. The MOC Crosses will accept and cross orders of any size, subject to the maximum allowable order size stated below. Any order greater than 1,000,000 shares, or that otherwise exceeds pre-set financial and regulatory risk management controls will be rejected. Y MAIN SESSION, CONDITIONAL SESSION AND MOC CROSSES: There are no special requirements or handling procedures for odd lot orders. VWAP CROSS: Odd-lot orders are ineligible to cross in the VWAP Cross; however, in the event an odd lot remains following a partial execution of a round lot order, the remaining or "residual" odd lot is eligible to cross. Odd-lot VWAP Cross orders will only cross with other residual odd-lot orders. Neither round-lot nor mixed-lot orders will cross with odd-lot orders in the VWAP Cross. Y MAIN SESSION, CONDITIONAL SESSION AND MOC CROSSES: There are no special requirements or handling procedures for mixed-lot orders. VWAP CROSS: Mixed-lot VWAP Cross orders will only cross with other mixed-lot orders. Neither round-lot nor odd-lot orders will cross with mixed-lot orders. Y CONDITIONAL SESSION: The Conditional Session accepts Conditional Orders, IOC orders and Day orders. Conditional Orders, IOC orders and Day orders may be market, limit or pegged order types (as described in Part III, Item 7) and may only be transmitted to the Conditional Session via Instinet Algorithms or the ILLC SOR. Direct Subscribers do not have access to the Conditional Session. Conditional Orders rest in the Conditional Session but are neither firm nor executable. Orders sent to the Conditional Session designated as "IOC" or "Day" orders are firm and executable. Orders sent to the Conditional Session do not interact with orders resting in any other ATS Crossing Session; orders are not routed from one crossing session to another. Conditional orders must contain, symbol, side, quantity and price instruction information. The transmission, receipt, and responses related to Firm-Up messages are automated and occur in in sub-second times. When contra-side Conditional Orders rest in the Conditional Session or when one or more Conditional Orders and a contra-side IOC or Day order rest in the Conditional Session such that there is a potential match, the ATS will send a Firm-Up request to the algorithm that entered the Conditional Order. When multiple Conditional Orders are present on the same side, the ATS will transmit the invitation to Firm-Up to one or more Conditional Orders based on price and time priority and the shares available in the contra side order. The ATS will utilize any limit price, Peg and Peg Offset instructions when determining price. For an execution to occur, the algorithm that has entered a Conditional Order and received a Firm-Up request, must respond to the request by transmitting an IOC or Day order. Conditional Session executions may occur when Conditional Session IOC orders interact with contra-side Conditional Session Day orders or Conditional Session Day orders interact with contra-side Conditional Session Day orders. Conditional Session IOC and Day orders are prioritized based on price and time priority. The ATS will utilize any limit price, Peg and Peg Offset instructions when determining price. Orders deemed to be removing liquidity from the ATS will receive all available price improvement. For two given orders, the order viewed by the Conditional Session as having been received first will be deemed to be adding liquidity. If the ILLC SOR or an ILLC Instinet Algorithms strategy modifies the terms of a Conditional Order or Day order, the modified order will receive a new entry time at the time of the modification. See Part III, Item 7 and Part III, Item 11 for more information regarding Conditional Orders and the Conditional Session. MAIN SESSION, VWAP CROSS AND MOC CROSSES: The Main Session, VWAP Cross and MOC Crosses do not send or receive any conditional orders, IOIs or actionable IOIs. CONDITIONAL SESSION: The Conditional Session is not available to Direct Subscribers of the ATS. The terms and conditions governing conditional orders are the same for all Indirect Subscribers and the Broker-Dealer Operator. MAIN SESSION, VWAP CROSS AND MOC CROSSES: The Main Session, VWAP Cross and MOC Crosses do not send or receive any conditional orders, IOIs or actionable IOIs. This is applicable to all Subscribers and the Broker-Dealer Operator. MAIN SESSION: The Main Session does not accept orders prior to the start of its regular trading hours (i.e., it does not accept orders between 8 p.m. and 4 a.m., ET). Orders received after opening are eligible for interaction in accordance with the standard prioritization, matching and execution rules identified at Part III Item 11(c) herein. The Main Session does not conduct an "opening cross." The Main Session does not conduct a "reopening cross" following a stoppage of trading during regular trading hours. Rather, orders are matched and executed in accordance with the Main Session's standard prioritization, matching and execution logic. CONDITIONAL SESSION: The Conditional Session does not accept orders prior to the start of its regular trading hours (i.e., it does not accept orders between 4 p.m. and 9:30 a.m., ET). Orders received after opening are eligible for interaction in accordance with the standard prioritization, matching and execution rules identified at Part III Item 11(c) herein. The Conditional Session does not conduct an "opening cross." The Conditional Session does not conduct a "reopening cross" following a stoppage of trading during regular trading hours. Rather, orders are matched and executed in accordance with the Conditional Session's standard prioritization, matching and execution logic VWAP AND MOC CROSSES (GENERALLY): The VWAP and MOC Crosses are all point-in-time crosses that accept orders from their designated start times until the time of the relevant crossing session. Generally, if a security is subject to a trading halt or other suspension, the VWAP and MOC Crosses will continue to accept orders for a given crossing session until the crossing session's designated start time. Stoppages that occur after a preliminary match (i.e., after a cross has occurred), but prior to close of trading, do not impact any preliminary matches (that is, preliminary matches will not be cancelled). VWAP CROSS: If a security is halted at the scheduled crossing time of the VWAP Cross, no cross will occur. Open orders will be cancelled back after the cross occurs. Trading halts or pauses do not impact the calculation of the VWAP Cross execution prices. MOC CROSSES: Subscribers may submit orders for the MOC Crosses at any time between 7:30 a.m. and the relevant crossing session's crossing time. If the primary listing exchange does not effect a closing cross for a security due to a trading halt or other stoppage in that security, the MOC Cross for that security will be cancelled unless the primary listing exchange disseminates a last closing price, in which case the execution price for that security will be the disseminated last closing price. Y MAIN SESSION: The Main Session does not effect a "reopening cross" following a stoppage of trading during the Main Session's regular trading hours. Rather, the Main Session will cross any open order following the stoppage (e.g., orders received prior to, or during, the stoppage in trading that were not subsequently canceled) in accordance with the Main Session's standard prioritization, matching and execution logic. CONDITIONAL SESSION: The Conditional Session does not effect a "reopening cross" following a stoppage of trading during the Conditional Session's regular trading hours. Rather, the Conditional Session will cross any open orders following the stoppage (e.g., orders received prior to, or during, the stoppage in trading that were not subsequently canceled) in accordance with the Conditional Session's standard prioritization, matching and execution logic. VWAP AND MOC CROSSES (GENERALLY): The VWAP and MOC Crosses are all point-in-time crosses that accept orders from their designated start times until the time of the relevant crossing session. The VWAP and MOC Crosses match and execute orders on a pro rata basis. Generally, if a security is subject to a trading halt or other suspension, the VWAP and MOC Crosses will continue to accept orders for a given crossing session until the crossing session's designated start time. Stoppages that occur after a preliminary match (i.e., after a cross has occurred), but prior to close of trading, do not impact any preliminary matches (that is, preliminary matches will not be cancelled). VWAP CROSS: If a security is halted at the scheduled crossing time of the VWAP Cross, no cross will occur. Open orders will be cancelled back. Trading halts or pauses do not impact the calculation of the VWAP Cross execution prices. MOC CROSSES: Subscribers may submit orders for the MOC Crosses at any time between 7:30 a.m. and the relevant crossing session's crossing time. If the primary listing exchange does not effect a closing cross for a security due to a trading halt or other stoppage in that security, the MOC Cross for that security will be cancelled unless the primary listing exchange disseminates a last closing price, in which case the execution price for that security will be the disseminated last closing price. Y N The ATS consists of multiple independent crossing sessions, the Main Crossing Session, the Conditional Crossing Session, the VWAP Crossing Session, and the MOC Crossing Session. Subscribers may transmit trading interest to one or more of these Crossing Sessions. All NMS Stocks are eligible for trading on the ATS. Orders in one crossing session do not interact with the orders or trading interest within another crossing session. MAIN SESSION: The Main Session allows Subscribers to enter orders in equity securities for prioritization and interaction with orders of other Subscribers who have also submitted orders to the Main Session for possible matching and execution. The Main Session matches orders on a continuous basis during its hours of operation. The Main Session does not permit the execution of orders outside the NBBO nor does it permit the execution of orders when the NBBO is locked or crossed. Direct Subscribers may designate their liquidity-adding orders, and ILLC may designate the liquidity-adding orders of Indirect Subscribers, as only eligible to interact with orders from certain Taker Tiers (further discussed in Part III Item 13). The Taker Tier function is only available in the Main Session. CONDITIONAL SESSION: The Conditional Session accepts Conditional Orders, IOC orders and Day orders. Conditional Orders, IOC orders and Day orders may only be transmitted to the Conditional Session via Instinet Algorithms or the ILLC SOR. Direct Subscribers do not have access to the Conditional Session. Conditional Orders rest in the Conditional Session but are neither firm nor executable. Conditional Session IOC orders and Day orders are firm and executable. See Part III, Item 7 and Item 9 for more information regarding Conditional Session IOC and Day orders and Conditional Orders. The Conditional Session matches orders on a continuous basis during its hours of operation. The Conditional Session does not permit the execution of orders outside the NBBO nor does it permit the execution of orders when the NBBO is locked or crossed. VWAP AND MOC CROSSES (GENERALLY): The VWAP and MOC Crosses are non-price discovery trading services. The VWAP Cross only accepts VWAP orders (i.e., Subscribers send orders to the VWAP Cross without a set limit price which, upon receiving a match for a given order, will receive an indicative fill priced at the midpoint of the symbol's NBBO). The MOC Crosses only accept market-on-close orders. The VWAP and MOC Crosses only accept orders with a time-in-force instruction of "day." VWAP CROSS: The VWAP Cross comprises a whole-day session that matches buy and sell orders entered by Subscribers prior to the opening of the regular trading session in U.S. markets. The VWAP Cross occurs at or near 9:00 a.m., Eastern Time. Order imbalance information for the VWAP Cross is not disseminated. Orders entered into the VWAP Cross are matched on a pro rata basis. Subscribers may elect to receive preliminary execution reports after the VWAP Cross, indicating the number of shares that have matched in the VWAP Cross. Upon receiving a match for a given order, Subscribers will receive an indicative fill priced at the midpoint of the symbol's NBBO. After the close of the primary trading session in the relevant U.S. market, the volume-weighted average price is calculated and Subscribers receive a report indicating the price at which their orders have been executed. ILLC calculates the VWAP price on the basis of the trading that takes place in the security during regular trading hours on the same day that the match occurs, including opening auctions and closing auctions (See Part III, Item 7 above and Part III, Item 11(c) below for additional detail regarding VWAP Calculation). Subscribers may indicate either a Buy Cash Constraint or a Sell Cash Constraint associated with an order or group of orders entered into the VWAP Cross, based on the midpoint of the prior day's closing price. (See also part III, Item 7) MOC CROSSES: The MOC Crosses consists of three (3) different crossing sessions: a NASDAQ Cross, an ARCA Cross, and a NYSE Cross. The NASDAQ Cross and ARCA Cross occur one minute prior to the relevant exchange's cutoff time for accepting Market On Close orders. The NYSE Cross occurs four minutes before the scheduled exchange closing auction. Currently, the NASDAQ Cross occurs at or near 3:54:00 p.m. (at or near 12:54:00 p.m. for trading days when the market close is scheduled for 1 p.m.). Currently, the ARCA Cross occurs at or near 3:58:00 p.m. (at or near 12:58:00 p.m. for trading days when the market close is scheduled for 1 p.m.). Currently, the NYSE Cross occurs at or near 3:56:00 p.m. (at or near 12:56:00 p.m. for trading days when the market close is scheduled for 1 p.m.). Order imbalance information is not disseminated. The MOC Crosses do not accept Sell Short orders. Upon Subscriber request, ILLC will configure a MOC Hosted Pool within the MOC Cross Session to cross orders at a specific time prior to the relevant exchange's cut off time for accepting Market On Close orders. If no specific time is requested and configured for the MOC Hosted Pool for orders to cross, then the cross will occur at the same times as the MOC Crosses above. See Section (c) below for information on MOC Crosses Counterparty Selection. Orders entered into the MOC Crosses are matched on a pro rata basis. Unmatched interest will either be cancelled back to the Subscriber or SOR, as applicable. Subscribers may elect to receive preliminary execution reports indicating the number of shares that have matched on a security-by-security basis or for all orders submitted to the MOC Crosses. The execution price of all orders matched in a MOC Cross is the security's closing auction price on the security's primary listing exchange or, where a closing auction does not occur, the last closing price disseminated by the primary listing exchange, if any. MAIN SESSION: Direct Subscribers may designate their liquidity-adding orders, and ILLC may designate the liquidity-adding orders of Indirect Subscribers, as only eligible to interact with orders from certain Taker Tiers (further discussed in Part III Item 13). The Taker Tier function is only available in the Main Session. CONDITIONAL SESSION: The Conditional Session is not available to Direct Subscribers of the ATS. The means and facilities identified in Part III, Item 11(a) are the same for all Indirect Subscribers and the Broker-Dealer Operator. VWAP AND MOC CROSSES: Regarding the VWAP and MOC Crosses, the means and facilities identified in Part III, Item 11(a) are the same for all Subscribers and the Broker-Dealer Operator. MAIN SESSION ORDER INTERACTION: The Main Session allocates, matches, and executes orders using price/time priority, subject to the terms of the orders. The Main Session matches eligible orders on a continuous basis during its hours of operation based on the pricing and priority rules outlined above. For derivatively-priced (e.g., pegged) orders, the time of order receipt will be deemed to be the time of each price change. However, where two pegged orders are deemed to be on time parity, the ATS will treat the order originally received first as having priority; no two orders can enter the Main Session at exactly the same time. For passive (i.e., nonmarketable) limit orders priced outside the NBBO, the time of order receipt will be deemed to be the time the order most recently became eligible to be executed at or within the NBBO. Limit orders priced through the NBBO and market orders are treated the same as market pegged orders. The Main Session does not permit the execution of orders when the NBBO is locked or crossed. MAIN SESSION PRICE IMPROVEMENT: Orders deemed to be removing liquidity from the ATS will receive all available price improvement. For two given orders, the order viewed by the Main Session as having been received first will be deemed to be adding liquidity. As noted above, the time of order receipt for any derivatively priced order is deemed to be the time of the most recent reference price change. As noted below, there is no mechanism for price improvement for orders executed in the VWAP or MOC Crosses. MAIN SESSION PRICE PROTECTION: The ATS offers Subscribers the ability to choose price protection mechanisms in the form of pegged orders. Orders submitted to the Main Session may be pegged to the NBB, NBO or to the midpoint of the NBBO. As noted below, there is no mechanism for price protection for orders executed in the VWAP or MOC Crosses. MAIN SESSION COUNTERPARTY TIERING: For orders submitted to the Main Session, Subscribers may use the ATS s counterparty tiering functionality to restrict eligible counterparties on an order-by-order basis. Specifically, Direct Subscribers may designate their liquidity-adding orders, and ILLC may designate the liquidity-adding orders of Indirect Subscribers, as only eligible to interact with orders from certain Taker Tiers. Taker Tier restrictions operate whenever an order would be deemed to add liquidity; the instruction is disregarded when an order would be deemed to remove liquidity (see Part III Item 13 for additional information). The counterparty tiering functionality is only available in the Main Session. CONDITIONAL SESSION ORDER INTERACTION: The Conditional Session accepts Conditional Orders, IOC orders and Day orders. Conditional Orders, IOC orders and Day orders may only be transmitted to the Conditional Session via Instinet Algorithms or the ILLC SOR. Direct Subscribers do not have access to the Conditional Session. Conditional Orders rest in the Conditional Session but are neither firm nor executable. Conditional Session IOC orders and Day orders are firm and executable. Conditional Session Conditional Orders, IOC orders and Day orders do not interact with orders resting in any other crossing session; orders are not routed from one crossing session to another. When contra-side Conditional Orders rest in the Conditional Session or when one or more Conditional Orders and a contra-side IOC or Day order rest in the conditional session such that there is a potential match, the ATS will send a Firm-Up request to the algorithm that entered the Conditional Order. When multiple Conditional Orders are present on the same side, the ATS will transmit the invitation to Firm-Up to one or more Conditional Orders based on price and time priority and the shares available in the contra side order. The ATS will utilize any limit price, Peg and Peg Offset instructions when determining price. For an execution to occur, the algorithm that has entered a Conditional Order and received a Firm-Up request must respond to the request by transmitting an IOC or Day order. Conditional Session executions may occur when Conditional Session IOC orders interact with contra-side Conditional Session Day orders or Conditional Session Day orders interact with contra-side Conditional Session Day orders. Conditional Session IOC and Day orders are prioritized based on price and time priority. The ATS will utilize any limit price, Peg and Peg Offset instructions when determining price. CONDITIONAL SESSION PRICE IMPROVEMENT: Upon Subscriber request, ILLC will configure a Hosted Pool to split price improvement equally between both sides of an execution for all executions within that pool. As noted above, IOC and Day orders are firm and executable. Where two firm orders (IOC or Day) are eligible to be matched at multiple price levels, they will execute at the midpoint of the eligible execution prices. For example, where the NBBO is $20.00 x $20.05, and the Conditional Session receives a limit order to buy at $20.10 and a limit order to sell at $20.02, the limit buy order will be repriced to the NBO (here $20.05) in calculating the midpoint of the orders eligible execution prices, and the orders will be executed at $20.035 (i.e., the midpoint of eligible execution prices, and not the midpoint of the NBBO). By default, and where a Hosted Pool has not been set up by ILLC to split any price improvement equally between both sides of execution, IOC and Day orders that are deemed to be removing liquidity from the Hosted Pool will receive all available price improvement. For two given orders, the order viewed by the Conditional Session as having been received first will be deemed to be adding liquidity. If the ILLC SOR or an ILLC Instinet Algorithms strategy modifies the terms of a Conditional Order or Day order, the modified order will receive a new entry time at the time of the modification. As noted above, the time of order receipt for any derivatively priced order is deemed to be the time of the most recent reference price change. CONDITIONAL SESSION PRICE PROTECTION: The ATS offers Subscribers the ability to choose price protection mechanisms in the form of pegged orders. Orders submitted to the Conditional Session may be pegged to the NBB, NBO or to the midpoint of the NBBO. CONDITIONAL SESSION COUNTERPARTY SELECTION: As described above, the Conditional Session is only available to Indirect Subscribers to the ATS (i.e., Subscribers who have elected to use the Instinet Algorithms or SOR that access the ATS). Certain of the Instinet Algorithms may, based upon predetermined routing logic, submit trading interest to the Conditional Session that is eligible to interact only with a specific subset of contra-side trading interest, such as orders submitted by one or more Instinet Algorithms or specific Indirect Subscribers (a Conditional Hosted Pool ). Upon request from an Indirect Subscriber, or in order to create a specific contra group for a specific algorithmic trading strategy, ILLC will create one or more Conditional Hosted Pools. Only Indirect Subscribers may request that ILLC set up a Conditional Hosted Pool. A Conditional Hosted Pool may be configured for the establishing Subscriber, or the establishing Subscriber may ask ILLC to liaise with one or more other selected Indirect Subscribers and include them in the Conditional Hosted Pool if they agree to join. In a Conditional Hosted Pool with multiple Subscribers, Subscribers cannot select to trade with a specific counterparty within the pool. ILLC does not set predetermined requirements to request or participate in a Conditional Hosted Pool. ILLC is under no obligation to maintain a Conditional Hosted Pool or any particular configuration of participants. Conditional Hosted Pools are segregated from the other firm orders and Conditionals in the Conditional Session and in other Conditional Hosted Pools. To participate in a Conditional Hosted Pool, the Instinet Algorithm or SOR will, on an order-by-order basis, include a Conditional Hosted Pool Target Counterparty FIX Tag on its algorithmic order. The Target Counterparty FIX Tag will designate that the order belongs to the selected Conditional Hosted Pool and permit the order to interact with contra-side orders within the selected Conditional Hosted Pool only. For clarity, orders in a Conditional Hosted Pool will be prioritized, matched, and executed in accordance with the Conditional Session standard matching and execution. See Part III Item 14 for additional information regarding Conditional Counterparty Selection. VWAP AND MOC CROSSES ORDER INTERACTION: The VWAP and MOC Crosses are all point-in-time crosses that match orders based on the pricing and priority rules outlined in Part III, Items 7(a) and 11(a). Orders entered into the VWAP Cross are matched on a pro rata basis. The MOC Cross system will first attempt to match orders entered by the same Subscriber to a MOC Cross (i.e. Subscriber priority), with any open order being matched on a pro rata size basis against any other Subscriber with an open order in the MOC Cross. For the VWAP Cross, upon receiving a match for a given order, Subscribers will receive an indicative fill priced at the midpoint of the symbol s NBBO. After the close of the primary trading session in the relevant U.S. market, ILLC calculates the volume-weighted average price and Subscribers receive a report indicating the price at which their orders have been executed (See discussion regarding the VWAP Calculation below). The execution price of all orders matched in a MOC Cross is the security s closing auction price on the security s primary listing exchange or, where a closing auction does not occur, the last closing price disseminated by the primary listing exchange. The VWAP and MOC Crosses do not permit the execution of orders when the NBBO is locked or crossed. ILLC calculates the execution prices of VWAP Cross transactions by using price, quantity, and sale condition data from trades disseminated by the SIP (i.e., the Consolidated Tape System ( CTS ) for Tape A and B securities and the Unlisted Trading Privileges ( UTP ) Plan for Tape C securities). Sale condition data is used to determine whether a transaction is eligible or ineligible for inclusion in Instinet s VWAP price calculations. Price and quantity information are used to calculate the ultimate VWAP Cross execution prices. SIP trades with the following sale conditions are excluded from the calculation: Average Price Trade; Cash Trade (same day settlement); Market Center Official Close; Next Day Trade (next day settlement); Market Center Official Open; Seller s Option (irregular settlement); Extended Hours Trade; Extended Hours Sold (out of sequence); Contingent Trade; Derivatively Priced; Qualified Contingent Trade; and Corrected Consolidated Close Price as per Listing Market (collectively Sale Conditions ). Odd lot trades are eligible for inclusion in ILLC s VWAP price calculations absent one of the above listed Sale Conditions. For each security receiving an indicative fill in the VWAP Cross, ILLC calculates the VWAP execution price in the following manner: the notional values (price*quantity) of each eligible transaction for a security are added to determine the security s total notional value executed during the trading day ( TNV ). The share quantities of each eligible transaction are added to determine the security s total shares traded ( TST ). The execution price for each security receiving an indicative fill in the VWAP Cross is equal to the security s TNV divided by the security s TST. Trading halts or pauses do not impact the calculation of the VWAP execution prices. VWAP AND MOC CROSSES PRICE IMPROVEMENT/PROTECTION: There is no mechanism for price improvement or price protection for orders executed in the VWAP or MOC Crosses. MOC CROSS COUNTERPARTY SELECTION At a Subscriber s request, the ATS will establish one or more hosted pools (a MOC Hosted Pool ) within the MOC Crosses, that enable that Subscriber to designate that its orders interact with orders entered by the same Subscriber or by other Subscribers who choose to participate in that Hosted Pool at the requesting Subscriber s invitation. To participate in a MOC Hosted Pool, the Subscriber will, on an order-by-order basis, include a custom FIX tag (a MOC Hosted Pool Target Counterparty FIX Tag ) on its MOC Cross order. The MOC Hosted Pool Target Counterparty FIX Tag will designate that the order belongs to the selected MOC Hosted Pool and permit the order to interact with contra-side orders within the selected MOC Hosted Pool only. In a MOC Hosted Pool with multiple Subscribers, Subscribers cannot add a FIX tag to select a certain counterparty on a specific trade. Orders in a MOC Hosted Pool will be prioritized, matched, and executed in accordance with the MOC Crosses Session standard matching and execution. See Part III Item 14 for additional information regarding MOC Counterparty Selection. Additionally, Subscribers may prevent orders from crossing with other orders within the MOC Hosted Pool by adding a separate custom FIX tag (a Trade Prevention Key ) that will prevent orders from crossing with other orders with the same FIX tag. Trade Prevention Keys may be used, for example, by Subscribers entering orders on behalf of the same beneficial owner to prevent those trades from crossing. . See Section 14 for additional information on the order-level cross-prevention functionality. ILLC does not set predetermined requirements for requesting or participating in a MOC Hosted Pool. ILLC is under no obligation to maintain a MOC Hosted Pool or any particular configuration of participants. MOC Hosted Pools are segregated from the MOC Crosses Session and other MOC Hosted Pools. At the establishing Subscriber s request, ILLC will configure a MOC Hosted Pool within the MOC Crosses Session to cross orders at a specific time prior to the relevant exchange s cut off time for accepting Market On Close orders. If no specific time is requested and configured for the MOC Hosted Pool for orders to cross, then the cross will occur at the same times as the MOC Crosses (as above). SHORT SALES (ALL CROSSING SESSIONS): The ATS is designed to operate in compliance with the requirements of Reg. SHO when accepting or executing orders. Accordingly, once a circuit breaker has been triggered, the Rule 201 price test restriction will apply to short sale orders in that security for the remainder of the day and the following day, unless an exemption applies. The ATS accepts orders marked short exempt from broker-dealer Subscribers. Such orders will be permitted to execute at the NBB when a circuit breaker is in effect. In the event the NBB is suspended or otherwise unavailable, such orders will be rejected. EXECUTION ERRORS (ALL CROSSING SESSIONS): For bona fide errors (as defined in FINRA Rule 6191) and other general errors made by ILLC or a client, ILLC handles execution errors occurring within the ATS in accordance with ILLC s internal policies and procedures (the Error Procedures ). The Error Procedures require that a relevant Principal or delegate be notified of any error occurring within the ATS. For general errors (e.g., technology, administrative) ILLC will determine the best course of action, including cancelling both sides of the erroneous trade, based on internal policy and, on a case-by-case basis, the facts and circumstances of each error. ILLC handles executions at clearly erroneous prices in accordance with the applicable rules of the SRO, including FINRA Rule 11891. Following a determination of erroneous trading by one or more SROs, ILLC will cancel any contemporaneous erroneous trade executed in the ATS. Only broker-dealer subscribers may submit orders as short-sell exempt. N MAIN SESSION SEGMENTATION (GENERALLY): ILLC segments Direct Subscribers' orders into three distinct Taker Tiers based upon the results of an objective post-trade analysis of the Subscriber's executed orders that were deemed to remove liquidity in the Main Session during a prior period (the "Mark-Out Analysis," further discussed below). The Taker Tier function is only available in the Main Session. ILLC, in its discretion, may assign a higher Taker Tier when an Indirect Subscriber has a low volume of trading in the prior period, the Indirect Subscriber has exhibited inconsistent behavior for the prior period, or for such other reasons as ILLC deems relevant. MARK-OUT ANALYSIS: ILLC calculates a price movement metric based on the midpoint price of the relevant security at the time of execution and a weighted average of the security's midpoint prices at various times after the fill (e.g., one second, ten seconds, 60 seconds) (the "Mark-Out"). On a monthly basis, ILLC calculates the average Mark-Out for each Direct Subscriber (or, as further discussed below, for each segment of the Direct Subscriber's order flow directed to the Main Session) based on the Subscriber's orders that were deemed to remove liquidity from the Main Session during the prior three (3) calendar months. For two given orders, the order viewed as having been received first will be deemed to be adding liquidity. As noted above, for orders in the Main Session, the time of order receipt for any derivatively priced order is deemed to be the time of the most recent reference price change. Executions occurring before or after market hours are excluded from the calculations, and executions that are anomalous due to unusual market movements (e.g. when a spread or a Mark-Out spread exceeds 5% of the execution price or when the market is crossed at the time of one or more of the post trade Mark-Outs) may also be excluded from the calculations. By default, ILLC performs a Mark-Out Analysis (and corresponding Taker Tier segmentation) at the MPID level for Direct Subscribers that are broker-dealers, and at the Subscriber account level for Direct Subscribers that are not broker-dealers. Alternatively, Direct Subscribers may request that ILLC perform the Mark-Out Analysis related to their orders on a FlowID level, as described below. Direct Subscribers may elect to have ILLC perform the Mark-Out Analysis related to their orders based upon one or more FlowIDs. A FlowID is an identifier that a Main Session Direct Subscriber may choose to apply to all or a subset of the Direct Subscriber's the Main Session order flow for the purposes of performing the Mark-Out Analysis. Direct Subscribers are not required to utilize Flow IDs, but if they choose to do so they may designate that ILLC associate their orders with a FlowID in one of two ways. Direct Subscribers may utilize a FIX tag to designate a FlowID on an order by order basis; or Direct Subscribers may designate that one or more of their FIX connections be associated with a FlowID. In either case, each order message transmitted by a Direct Subscriber that chooses to utilize FlowIDs will be associated with a maximum of one (1) FlowID. Where a Direct Subscriber has requested that ILLC associate its order flow with one or more FlowIDs, Taker Tier segmentation will be assessed at the FlowID level. Direct Subscribers may utilize up to four FlowIDs on some or all of their order flow, or may choose to not utilize FlowIDs. Broker-dealer Direct Subscribers may utilize more than one FlowID for each MPID utilized by the Subscriber. For instance, if a broker-dealer Direct Subscriber accesses the Main Session through two (2) MPIDs, that broker-dealer Direct Subscriber may utilize up to four FlowIDs for each MPID (that is, up to eight (8) FlowIDs in total). Any Direct Subscriber that accesses the Main Session via direct-FIX connection may utilize the FlowIDs by FIX tag or connection. ILLC may ignore a FlowID created intra-month, or where a FlowID does not otherwise have sufficient volume associated with it, when assessing the Subscriber's Taker Tier, and will aggregate that flow under an existing FlowID. ILLC does not perform a Mark-Out Analysis for Indirect Subscribers. Accordingly, ILLC does not segment Indirect Subscribers. All Indirect Subscribers are assigned to Taker Tier 1. The Taker Tier function is only available in the Main Session. MAIN SESSION TAKER TIERS: ILLC assigns Taker Tiers by sorting Direct Subscribers (or the relevant portion of the Subscriber's order flow) by their Mark-Out scores. The three Taker Tiers are called "1" or Low Impact, "2" or Medium Impact, and "3" or High Impact. Taker Tier 1 contains Subscribers who exhibit the lowest Mark-Out scores (that is, stocks tend to exhibit the least amount of movement in the NBBO over the post-trade Mark-Out time horizons in the removing Subscriber's favor) relative to other Subscribers' liquidity removing flow, and the Taker Tier 3 contains Subscribers who exhibit the highest Mark-Out scores relative to other Subscribers' taking flow. When a new Direct Subscriber is on-boarded, ILLC will assign the Subscriber a Taker Tier based on ILLC's subjective judgement regarding the expected nature of the Subscribers' order flow. ILLC may periodically reassess and modify the metrics (e.g. Mark-Out time durations, weightings, etc.) used to determine the Taker Tiers. The ATS, by default, will allow a Subscriber's orders to interact with orders from any Subscriber. However, Subscribers may, subject to the below, designate their Main Session liquidity-adding orders as only eligible to interact with the Main Session orders of Subscribers in specific Taker Tiers (see Part III Section 13 for additional information regarding Taker Tiers). Note that a Taker Tier restriction only applies when the Subscriber's order is deemed to add liquidity and is only available in the Main Session. For instance, where Subscriber A designates its liquidity-adding orders as only eligible to interact with Taker Tier 1 orders, Subscriber A's order may nevertheless interact with Taker Tiers 2 and 3 when Subscriber A's order is deemed to remove liquidity. Direct Subscribers may designate their Main Session liquidity-adding orders as only eligible to interact with one or more Taker Tiers through the use of a unique FIX tag. Indirect Subscribers may not designate their liquidity-adding orders as only eligible to interact with one or more Taker Tiers. However, the Indirect Subscriber's manner of order entry to the Main Session (e.g., SOR or Instinet Algorithms) as well as the specific SOR configuration or Instinet Algorithms strategy utilized, may include instructions that limit the Taker Tier(s) with which a liquidity providing order may interact. Such order instructions are made at ILLC's sole discretion. CONDITIONAL SESSION, VWAP AND MOC CROSSES: Orders and trading interest in the Conditional Session or the VWAP and MOC Crosses are not segmented into categories, classifications, tiers, or levels. MAIN SESSION: Direct Subscribers may designate their liquidity-adding orders as only eligible to interact with one or more Taker Tiers through the use of a unique FIX tag. Indirect Subscribers may not designate their liquidity-adding orders as only eligible to interact with one or more Taker Tiers. However, the Indirect Subscriber's manner of order entry to the Main Session (e.g., SOR or Instinet Algorithms) as well as the specific SOR configuration or Instinet Algorithms strategy utilized, may include instructions that limit the Taker Tier(s) with which a liquidity providing order may interact. Such order instructions are made at ILLC's sole discretion. CONDITIONAL SESSION, VWAP AND MOC CROSSES: Orders and trading interest in the Conditional Session or the VWAP and MOC Crosses are not segmented into categories, classifications, tiers, or levels. MAIN SESSION: Upon written request, ILLC will inform a Subscriber of its designated Taker Tier(s) for its order flow to the Main Session. A Subscriber cannot contest its designated Taker Tier. CONDITIONAL SESSION, VWAP AND MOC CROSSES: Orders and trading interest in the Conditional Session and the VWAP and MOC Crosses are not segmented into categories, classifications, tiers, or levels. Y N MAIN SESSION: The ATS, by default, allows orders submitted to the Main Session by the same Subscriber to cross. Subscribers may, however, elect to prevent orders submitted by the same Subscriber from interacting with one another or with orders of one or more of their affiliates ( Self-Crossing Prevention ). CONDITIONAL SESSION: The ATS, by default, allows orders submitted to the Conditional Session by the same Subscriber to cross. Subscribers may, however, elect to apply Self-Crossing Prevention. As described above, certain of the Instinet Algorithms or the SOR will, based upon predetermined routing logic and the addition of a Conditional Hosted Pool Target Counterparty FIX Tag, submit trading interest to the Conditional Session that is only eligible to interact with one or more counterparties in the selected Conditional Hosted Pool. Conditional Hosted Pools are segregated from the other firm orders and Conditionals in the Conditional Session and in other Conditional Hosted Pools. Orders with a Conditional Hosted Pool Target Counterparty FIX Tag instruction will be prioritized, matched, and executed in accordance with the Conditional Session standard matching and execution logic. The Conditional Hosted Pool Target Counterparty FIX Tag or Conditional Hosted Pool Functionality does not currently support elections based on Subscriber characteristics (e.g., the rate at which a subscriber submits a Firm-Up message in response to a trading opportunity in the Conditional Session). VWAP CROSSES: The ATS, by default, allows orders submitted to the VWAP Cross by the same Subscriber to cross. Subscribers may, however, elect to apply Self-Crossing Prevention. VWAP Cross Subscribers may also select a preference to self-cross, in which case the ATS will prioritize orders submitted by the same Subscriber to the VWAP Cross for crossing.. MOC CROSSES: The ATS, by default, will prioritize orders submitted by the same Subscriber for crossing. Depending on a number of factors, this can lower the cost of execution for the Subscriber. Subscribers may, however, elect to apply Self-Crossing Prevention. MOC CROSS COUNTERPARTY SELECTION: At a Subscriber s request, the ATS will establish a MOC Hosted Pool that enables that Subscriber to designate that its orders interact with orders entered by the same Subscriber or by other Subscribers who choose to participate in that Hosted Pool at the requesting Subscriber s invitation. MOC Hosted Pools are segregated from the other orders in the MOC Session and in other MOC Hosted Pools. As described in Section 11(c), a Subscriber may, on an order-by-order basis, include a MOC Hosted Pool Target Counterparty FIX Tag on a MOC Cross order. The MOC Hosted Pool Target Counterparty FIX Tag will designate that the order belongs to a selected MOC Hosted Pool and permit the order to interact with contra-side orders within the selected MOC Hosted Pool only A Subscriber may request that a MOC Hosted Pool cross orders at a specific time prior to the relevant exchange s cut-off time for accepting MOC orders. In addition to Self-Crossing Prevention, as described in Section 11(c), A Subscriber may request functionality that will enable Subscribers within a MOC Hosted Pool to prevent orders from executing against each other on an order-by-order basis, with the addition of a custom FIX tag (a Trade Prevention Key ). MOC Hosted Pool Subscribers may control which orders cannot match in the Hosted Pool on an order-by order basis. Adding a specific Trade Prevention Key to an order will prevent it from crossing with orders bearing the same FIX tag in the same MOC Hosted Pool. The orders prevented from crossing may be from the same Subscriber or among different Subscribers. Subscribers may add a Trade Prevention Key, for example, to prevent crosses among underlying accounts with the same beneficial owner. MOC Cross orders in an MOC Hosted Pool with a MOC Hosted Pool Target Counterparty FIX Tag instruction will be prioritized, matched, and executed in accordance with the MOC Session standard matching and execution logic. Y N MAIN SESSION, VWAP CROSS, AND MOC CROSSES: Subscriber orders and trading interest bound for or resting in the Main Session, the VWAP Cross, or the MOC Cross are not displayed to any Persons for the purposes of the display requirements under Rule 301(b)(3) of Regulation ATS. However, certain information in the ATS is provided on a real-time, continuous basis, only to the Broker-Dealer Operator's SOR. The SOR receives a data feed that contains aggregated and anonymized buy and sell information for resting orders in the CBX Main Session. The data feed includes symbol, side (buy or sell), quantity available for all available price levels where there is an open order at that price level, and timestamp of the last price or size change in the feed for that security. The data feed includes orders from Direct and Indirect subscribers sent to the Main session. In a situation where all of the interest on a given side of the market is reflected by a single order, that interest will still be included in the feed. The interest will be anonymized, and the feed will not reflect that it is comprised of a single order. The feed is used by the SOR for the purposes of routing decisions and is not used for non-routing purposes. In addition, when the SOR of the Broker-Dealer Operator routes an order to the ATS, it necessarily knows that such order was routed to the ATS. Subscribers may not opt out of having their resting orders included in the data feeds. CONDITIONAL SESSION: For the Conditional Session, when there is a potential match, the ATS will send a Firm-Up message, which includes symbol, side, size and price of the contra-side interest. This information is only sent to the ILLC Instinet Algorithms. Direct Subscribers are not eligible to send orders to the Conditional Session. The transmission, receipt, and responses related to Firm-Up messages are automated and occur in in sub-second times. As indicated above, the information is made known only to the Broker-Dealer Operator's smart order routing technology, as described in Part II, Item 7(a). N N Y N APPLICABLE TO ALL CROSSING SESSIONS: Subscribers are not charged fees to access the ATS (e.g., monthly access fees, hookup fees, port fees, or connection fees). ILLC charges Subscribers per share fees for executions in the ATS. Per share fees are not standardized, are individually negotiated, and may differ depending on the means of accessing the ATS (i.e., Direct vs Indirect). The fee associated with the ATS may vary within the relevant ranges below based on whether the Subscriber elects All-In or Cost Plus pricing, the Subscriber's trading volume and order characteristics (e.g., order capacity, adding or removing liquidity, whether the orders generally meet the definition of a "Retail Investor Order" under FINRA Rule 6191, self-crossing), and the level of service required by each client, including, but not limited to, whether a client will utilize ILLC execution services, research services, analytics tools, Instinet Algorithms, or OMS/EMS systems. Additionally, the level of custom modifications to each product requested by the client may impact pricing. ILLC is assessed certain Consolidated Audit Trail (CAT) regulatory fees relating to trading on the ATS as an execution venue. In each transaction on the ATS where?the buying and selling Subscribers are brokers, or the buying Subscriber is an institution and the selling Subscriber is a broker, INCA is identified as the CAT Executing Broker for the buyer and the Subscriber is reported as the CAT Executing Broker for the seller. FINRA assesses CAT fees (i) on ILLC, on behalf of the buying Subscriber, and (ii) directly on the selling Subscriber. If the buying Subscriber has a cost-plus pricing arrangement with ILLC, ILLC passes through to the buying Subscriber the CAT-related fees that ILLC is assessed on behalf of the buying Subscriber. ? In each transaction on the ATS where the buying and selling Subscribers are both institutions, or the buying Subscriber is a broker and the selling Subscriber is an institution, INCA is identified as the CAT Executing Broker for both the Buyer and the Seller. FINRA assesses CAT fees on ILLC for both the Buyer and the Seller. In this case, ILLC will pass through the CAT fees to Subscribers that utilize the Cost-Plus Model. MAIN SESSION: Per share fees charged to Direct Subscribers accessing the Main Session through a direct connection (rather than through an Instinet Trading Product or by submitting their order flow to an Instinet Trading Desk) range between $0.00 and $0.025. CONDITIONAL SESSION: Per share fees charged to Indirect Subscribers accessing the Conditional Session (including Conditional Session Hosted Pools) through an Instinet Trading Product or by submitting their order flow to an Instinet Trading Desk range between $0.00 and $0.025. VWAP CROSS: For Direct Subscriber order flow to the VWAP Cross, Subscribers are charged fees in the range of $0.00015 - $0.0050 per share. In addition to the factors discussed above, the fee associated with the VWAP Cross may vary within the ranges above based on whether the Subscriber has elected to utilize the self-crossing feature of the VWAP Cross (the fees associated with a self-cross are individually negotiated and may vary based on the client's clearing type and is offered as a lower cost option to other market centers). MOC CROSS: For Direct Subscriber order flow to the MOC Cross (including MOC Cross Hosted Pools), Subscribers are charged a commission in the range of $0.0001 - $0.0010 per share. Fees charged for Indirect Subscriber order flow (orders and trading interest routed by an Instinet Trading Product or by submitting their order flow to an Instinet Trading Desk) are not standardized and are individually negotiated. ILLC generally operates under two pricing models, All-In and Cost Plus. Clients utilizing the All-In pricing model pay an agreed upon per-share commission regardless of destination. Under this pricing model, the cost of execution is included in the client's negotiated commission rate ($0.0001 - $0.10 per share). Subscribers utilizing the Cost Plus model would pay the cost of execution plus commission (e.g., client would pay a fee per share for executions in the ATS within the above stated ranges for each Crossing Session plus that client's individually negotiated commission). Under the Cost Plus model, ILLC charges a $0.0001 - $0.10 per share commission in addition to the per-share fee for executions in the ATS. The variables that impact pricing include the expected trading volume of the Subscriber and the level of service it requires, including, but not limited to, clearing type, whether it will utilize ILLC execution services, analytics tools, Instinet Algorithms, or OMS/EMS systems. Additionally, the level of custom modifications to each product requested by the client may impact pricing. A client's classification as broker-dealer or institutional is not considered with respect to its commission rates. ILLC does not offer rebates or discounted fees for trading in the the ATS. APPLICABLE TO ALL CROSSING SESSIONS: The ATS may suspend matching for technology, compliance, or risk related reasons. Matching can be paused while new orders will continue to be accepted and prioritized as they would during normal trading yet without any matching taking place. The ATS also has the ability to reject all new orders should situations dictate. Each Crossing Session can be paused individually without affecting trading on the Cross(es) not subject to the suspension or stoppage. ILLC trading desk personnel provide clients notice of a suspension or stoppage in trading on an as needed basis. Clients may request that notice of a suspension or stoppage of trading be provided. The ATS may suspend trading in each Crossing Session, independently, for individual NMS stocks with a symbology update. The ATS Principal monitors activity on the ATS for compliance with Reg. ATS and SCI, including whether, during at least four of the last six months, it had with respect to NMS stocks (i) 5% or more in any single NMS stock, and 0.25% or more in all NMS stocks, of the average daily dollar volume reported by an effective transaction reporting plan, or (ii) 1% or more, in all NMS stocks, of the average daily dollar volume reported. If the ATS had 0.25% or more of the average daily dollar volume reported by an effective transaction reporting plan in all NMS stocks, and an individual security has breached the 5% threshold in three out of six months, the symbol will be set to "route only" mode. The "route only" mode will prevent the Instinet Trading products from routing the symbol to the ATS. Orders in such a symbol routed to the ATS directly via FIX or via third-party algorithms, smart routers, or otherwise will be rejected. When the 1% threshold for all NMS stocks is breached for the first, second, and third time in a six month span, ILLC may take a range of action, in its sole discretion. MAIN SESSION: Once a suspension or stoppage is lifted trading in the Main Session will begin in each security with the first quote update that appears on the consolidated tape. CONDITIONAL SESSION: Once a suspension or stoppage is lifted trading in the Conditional Session will begin in each security with the first quote update that appears on the consolidated tape. VWAP AND MOC CROSSES (GENERALLY): If a security is subject to a trading halt or other suspension, the VWAP and MOC Crosses will continue to accept orders for a given crossing session until the crossing session's designated start time. Stoppages that occur after a preliminary match (i.e., after a cross has occurred), but prior to close of trading, do not impact any preliminary matches (that is, preliminary matches will not be cancelled). VWAP CROSS: If a security is halted at the scheduled crossing time of the VWAP Cross, no cross will occur and open orders will be cancelled back or remain eligible for that day's subsequent VWAP Cross(es), depending on Subscriber instruction. Trading halts or pauses do not impact the calculation of the VWAP Cross execution prices. MOC CROSSES: Subscribers may submit orders for the MOC Crosses at any time between 7:30 a.m. and the relevant crossing session's crossing time. If the primary listing exchange does not effect a closing cross for a security due to a trading halt or other stoppage in that security, the MOC Cross for that security will be cancelled unless the primary listing exchange disseminates a last closing price, in which case the execution price for that security will be the disseminated last closing price. Clients may request that ILLC provide notice of a suspension or stoppage of trading. Those clients who have requested such notice will be notified as soon as practicable. Clients who have not requested notice of a suspension or stoppage of trading may be provided notice on an as needed basis. ILLC reports equities transactions executed in the ATS to the FINRA/NASDAQ Trade Reporting Facility (TRF) located in Carteret. ILLC maintains an audit trail of orders and executions on the ATS and submits Consolidated Audit Trail ("CAT") reports to FINRA as required by FINRA's CAT Rules. Y ILLC is a self-clearing broker and a member of the National Securities Clearing Corporation ("NSCC") and the Depository Trust Company ("DTC"). ILLC becomes a counterparty to each side of any transaction executed on the ATS. ILLC does not custody funds or securities for Subscribers and settles all transactions effected on the ATS with the Subscriber or the Subscriber's custodian, prime broker or other settlement agent, in accordance with settlement instructions provided by the Subscriber to ILLC. For Subscribers settling via the facilities of the NSCC, ILLC submits each transaction to the NSCC for clearance (either for trade matching with the NSCC member contra or on a locked-in basis, such as through a Qualified Special Representative arrangement), with the legal obligation for settlement of the transaction transferring from ILLC to NSCC once NSCC has novated the submitted transaction and final settlement through the facilities of the DTC. For Subscribers settling via the facilities of the DTC, ILLC submits transaction information to DTC for affirmation prior to final settlement via the facilities of the DTC. In a few circumstances, ILLC gives up trades in real time to the client's clearing broker to settle the transaction, ILLC utilizes certain Broadridge Financial Solutions, Inc. systems and services for the purposes of recordkeeping, clearance and trade settlement processing. Y The ATS is designed to operate in compliance with all applicable rules and regulations (e.g., Reg NMS, Reg SHO, etc.). The ATS can also use market data from the SIP to interpret any condition disseminated by the marketplace (e.g. Limit Up/Limit Down bands). MAIN SESSION: The Main Session matching engine consumes the Securities Information Processor feed ("SIP") for matching purposes within the NBBO. The SIP data feeds are combined by an Instinet market data consolidator that sits outside of the ATS and calculates a consolidated NBBO based on the SIP. The ATS utilizes the NBBO to price, prioritize and execute orders as described in Part III, Item 11. CONDITIONAL SESSION: The Conditional Session matching engine consumes the SIP for matching purposes within the NBBO. The SIP data feeds are combined by an Instinet market data consolidator that sits outside of the ATS and calculates a consolidated NBBO based on the SIP. The ATS utilizes the NBBO to price, prioritize and execute orders as described in Part III, Item 11. VWAP AND MOC CROSSES: The VWAP and MOC Crosses are non-real time, and use end of day reference data to price trades from the SIP. The SIP data feeds are combined by an ILLC market data consolidator that sits outside of the ATS and calculates a consolidated NBBO based on the SIP. ILLC computes the VWAP values based on trades received from the SIP feeds (Tape A, B & C) and determines their VWAP-eligibility based on the trade condition codes provided by the SIP. VWAP CALCULATION: ILLC calculates the execution prices of VWAP Cross transactions by using price, quantity, and sale condition data from trades disseminated by the SIP (i.e., the Consolidated Tape System ("CTS") for Tape A and B securities and the Unlisted Trading Privileges ("UTP") Plan for Tape C securities). Sale condition data is used to determine whether a transaction is eligible or ineligible for inclusion in Instinet's VWAP price calculations. Price and quantity information are used to calculate the ultimate VWAP Cross execution prices. SIP trades with the following sale conditions are excluded: Average Price Trade; Cash Trade (same day settlement); Market Center Official Close; Next Day Trade (next day settlement); Market Center Official Open; Seller's Option (irregular settlement); Extended Hours Trade; Extended Hours Sold (out of sequence); Contingent Trade; Derivatively Priced; Qualified Contingent Trade; and Corrected Consolidated Close Price as per Listing Market (collectively "Sale Conditions"). Odd lot trades are eligible for inclusion in ILLC's VWAP price calculations absent one of the above listed Sale Conditions. For each security receiving an indicative fill in a VWAP Cross, ILLC calculates the VWAP Cross execution price in the following manner: the notional values (price*quantity) of each eligible transaction for a security are added to determine the security's total notional value executed during the trading day ("TNV"). The share quantities of each eligible transaction are added to determine the security's total shares traded ("TST"). The execution price for each security receiving an indicative fill in a VWAP Cross is equal to the security's TNV divided by the security's TST. Trading halts or pauses do not impact the calculation of the VWAP Cross execution prices. Y N N N
