As of May 1, 2021, as permitted by regulations adopted by the Securities and Exchange Commission, you may not be receiving paper copies of the Portfolio’s shareholder reports from the insurance company that offers your contract unless you specifically requested paper copies from the insurance company or from your financial intermediary. Instead of delivering paper copies of the reports, the insurance company may choose to make the reports available on a website, and will notify you by mail each time a report is posted and provide you with a website link to access the report. Instructions for requesting paper copies will be provided by your insurance company.

You may elect to receive all future reports in paper free of charge from the insurance company. You can inform the insurance company or your financial intermediary that you wish to continue receiving paper copies of your shareholder reports by following the instructions provided by the insurance company or by contacting your financial intermediary. Your election to receive reports in paper will apply to all portfolio companies available under your contract with the insurance company.

As a shareholder of the Portfolio, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, contingent deferred sales charges on redemptions and (2) ongoing costs, including management fees; distribution (12b-1) fees; and other Portfolio expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Portfolio and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period as indicated below.

Actual Expenses

The table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period. The estimate of expenses does not include fees or other expenses of any variable insurance product. If such expenses were included, the estimate of expenses you paid during the period would be higher and your ending account value would be lower.

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and hypothetical expenses based on the Portfolio’s actual expense ratio and an assumed annual rate of return of 5% before expenses, which is not the Portfolio’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Portfolio and other funds by comparing this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. The estimate of expenses does not include fees or other expenses of any variable insurance product. If such expenses were included, the estimate of expenses you paid during the period would be higher and your ending account value would be lower.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), or contingent deferred sales charges on redemptions. Therefore, the second line of each class’ table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

NOTE A: Significant Accounting Policies

The AB Balanced Hedged Allocation Portfolio (the “Portfolio”) (formerly known as AB Balanced Wealth Strategy Portfolio) is a series of AB Variable Products Series Fund, Inc. (the “Fund”). The Portfolio’s investment objective is to maximize total return consistent with the determination of AllianceBernstein L.P. (the “Adviser”) of reasonable risk. The Portfolio is diversified as defined under the Investment Company Act of 1940. The Fund was incorporated in the State of Maryland as an open-end series investment company. The Fund offers 10 separately managed pools of assets which have differing investment objectives and policies. The Portfolio offers Class A and Class B shares. Both classes of shares have identical voting, dividend, liquidating and other rights, except that Class B shares bear a distribution expense and have exclusive voting rights with respect to the Class B distribution plan.

The Portfolio offers and sells its shares only to separate accounts of certain life insurance companies for the purpose of funding variable annuity contracts and variable life insurance policies. Sales are made without a sales charge at the Portfolio’s net asset value per share.

The financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”), which require management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and amounts of income and expenses during the reporting period. Actual results could differ from those estimates. The Portfolio is an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. The following is a summary of significant accounting policies followed by the Portfolio.

1. Security Valuation

Portfolio securities are valued at their current market value determined on the basis of market quotations or, if market quotations are not readily available or are deemed unreliable, at “fair value” as determined in accordance with procedures established by and under the general supervision of the Fund’s Board of Directors (the “Board”).

In general, the market values of securities which are readily available and deemed reliable are determined as follows: securities listed on a national securities exchange (other than securities listed on the NASDAQ Stock Market, Inc. (“NASDAQ”)) or on a foreign securities exchange are valued at the last sale price at the close of the exchange or foreign securities exchange. If there has been no sale on such day, the securities are valued at the last traded price from the previous day. Securities listed on more than one exchange are valued by reference to the principal exchange on which the securities are traded; securities listed only on NASDAQ are valued in accordance with the NASDAQ Official Closing Price; listed or over the counter (“OTC”) market put or call options are valued at the mid level between the current bid and ask prices. If either a current bid or current ask price is unavailable, the Adviser will have discretion to determine the best valuation (e.g., last trade price in the case of listed options); open futures are valued using the closing settlement price or, in the absence of such a price, the most recent quoted bid price. If there are no quotations available for the day of valuation, the last available closing settlement price is used; U.S. Government securities and any other debt instruments having 60 days or less remaining until maturity are generally valued at market by an independent pricing vendor, if a market price is available. If a market price is not available, the securities are valued at amortized cost. This methodology is commonly used for short term securities that have an original maturity of 60 days or less, as well as short term securities that had an original term to maturity that exceeded 60 days. In instances when amortized cost is utilized, the Valuation Committee (the “Committee”) must reasonably conclude that the utilization of amortized cost is approximately the same as the fair value of the security. Factors the Committee will consider include, but are not limited to, an impairment of the creditworthiness of the issuer or material changes in interest rates. Fixed-income securities, including mortgage-backed and asset-backed securities, may be valued on the basis of prices provided by a pricing service or at a price obtained from one or more of the major broker-dealers. In cases where broker-dealer quotes are obtained, the Adviser may establish procedures whereby changes in market yields or spreads are used to adjust, on a daily basis, a recently obtained quoted price on a security. Swaps and other derivatives are valued daily, primarily using independent pricing services, independent pricing models using market inputs, as well as third party broker-dealers or counterparties. Open-end mutual funds are valued at the closing net asset value per share, while exchange traded funds are valued at the closing market price per share.

Securities for which market quotations are not readily available (including restricted securities) or are deemed unreliable are valued at fair value as deemed appropriate by the Adviser. Factors considered in making this determination may include, but are not limited to, information obtained by contacting the issuer, analysts, analysis of the issuer’s financial statements or other available documents. In addition, the Portfolio may use fair value pricing for securities primarily traded in non-U.S.

10

markets because most foreign markets close well before the Portfolio values its securities at 4:00 p.m., Eastern Time. The earlier close of these foreign markets gives rise to the possibility that significant events, including broad market moves, may have occurred in the interim and may materially affect the value of those securities. To account for this, the Portfolio generally values many of its foreign equity securities using fair value prices based on third party vendor modeling tools to the extent available.

2. Fair Value Measurements

In accordance with U.S. GAAP regarding fair value measurements, fair value is defined as the price that the Portfolio would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a framework for measuring fair value, and a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability (including those valued based on their market values as described in Note A.1 above). Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Portfolio. Unobservable inputs reflect the Portfolio’s own assumptions about the assumptions that market participants would use in pricing the asset or liability based on the best information available in the circumstances. Each investment is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three-tier hierarchy of inputs is summarized below.

The fair value of debt instruments, such as bonds, and over-the-counter derivatives is generally based on market price quotations, recently executed market transactions (where observable) or industry recognized modeling techniques and are generally classified as Level 2. Pricing vendor inputs to Level 2 valuations may include quoted prices for similar investments in active markets, interest rate curves, coupon rates, currency rates, yield curves, option adjusted spreads, default rates, credit spreads and other unique security features in order to estimate the relevant cash flows which are then discounted to calculate fair values. If these inputs are unobservable and significant to the fair value, these investments will be classified as Level 3.

Where readily available market prices or relevant bid prices are not available for certain equity investments, such investments may be valued based on similar publicly traded investments, movements in relevant indices since last available prices or based upon underlying company fundamentals and comparable company data (such as multiples to earnings or other multiples to equity). Where an investment is valued using an observable input, such as another publicly traded security, the investment will be classified as Level 2. If management determines that an adjustment is appropriate based on restrictions on resale, illiquidity or uncertainty, and such adjustment is a significant component of the valuation, the investment will be classified as Level 3. An investment will also be classified as Level 3 where management uses company fundamentals and other significant inputs to determine the valuation.

Options are valued using market-based inputs to models, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency, where such inputs and models are available. Alternatively, the values may be obtained through unobservable management determined inputs and/or management’s proprietary models. Where models are used, the selection of a particular model to value an option depends upon the contractual terms of, and specific risks inherent in, the option as well as the availability of pricing information in the market. Valuation models require a variety of inputs, including contractual terms, market prices, measures of volatility and correlations of such inputs. Exchange traded options generally will be classified as Level 2. For options that do not trade on an exchange but trade in liquid markets, inputs can generally be verified and model selection does not involve significant management judgment. Options are classified within Level 2 on the fair value hierarchy when all of the significant inputs can be corroborated to market evidence. Otherwise such instruments are classified as Level 3.

Valuations of mortgage-backed or other asset-backed securities, by pricing vendors, are based on both proprietary and industry recognized models and discounted cash flow techniques. Significant inputs to the valuation of these instruments are value of the collateral, the rates and timing of delinquencies, the rates and timing of prepayments, and default and loss expectations, which are driven in part by housing prices for residential mortgages. Significant inputs are determined based

11

on relative value analyses, which incorporate comparisons to instruments with similar collateral and risk profiles, including relevant indices. Mortgage and asset-backed securities for which management has collected current observable data through pricing services are generally categorized within Level 2. Those investments for which current observable data has not been provided are classified as Level 3.

Other fixed income investments, including non-U.S. government and corporate debt, are generally valued using quoted market prices, if available, which are typically impacted by current interest rates, maturity dates and any perceived credit risk of the issuer. Additionally, in the absence of quoted market prices, these inputs are used by pricing vendors to derive a valuation based upon industry or proprietary models which incorporate issuer specific data with relevant yield/spread comparisons with more widely quoted bonds with similar key characteristics. Those investments for which there are observable inputs are classified as Level 2. Where the inputs are not observable, the investments are classified as Level 3.

The following table summarizes the valuation of the Portfolio’s investments by the above fair value hierarchy levels as of June 30, 2022:

3. Currency Translation

Assets and liabilities denominated in foreign currencies and commitments under forward currency exchange contracts are translated into U.S. dollars at the mean of the quoted bid and ask prices of such currencies against the U.S. dollar. Purchases and sales of portfolio securities are translated into U.S. dollars at the rates of exchange prevailing when such securities were acquired or sold. Income and expenses are translated into U.S. dollars at rates of exchange prevailing when accrued.

Net realized gain or loss on foreign currency transactions represents foreign exchange gains and losses from sales and maturities of foreign fixed income investments, holding of foreign currencies, currency gains or losses realized between the trade

12

and settlement dates on foreign investment transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on the Portfolio’s books and the U.S. dollar equivalent amounts actually received or paid. Net unrealized currency gains and losses from valuing foreign currency denominated assets and liabilities at period end exchange rates are reflected as a component of net unrealized appreciation or depreciation of foreign currency denominated assets and liabilities.

4. Taxes

It is the Portfolio’s policy to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its investment company taxable income and net realized gains, if any, to shareholders. Therefore, no provisions for federal income or excise taxes are required. The Portfolio may be subject to taxes imposed by countries in which it invests. Such taxes are generally based on income and/or capital gains earned or repatriated. Taxes are accrued and applied to net investment income, net realized gains and net unrealized appreciation/depreciation as such income and/or gains are earned.

In accordance with U.S. GAAP requirements regarding accounting for uncertainties in income taxes, management has analyzed the Portfolio’s tax positions taken or expected to be taken on federal and state income tax returns for all open tax years (the current and the prior three tax years) and has concluded that no provision for income tax is required in the Portfolio’s financial statements.

5. Investment Income and Investment Transactions

Dividend income is recorded on the ex-dividend date or as soon as the Portfolio is informed of the dividend. Interest income is accrued daily. Investment transactions are accounted for on the date the securities are purchased or sold. Investment gains or losses are determined on the identified cost basis. The Portfolio amortizes premiums and accretes discounts as adjustments to interest income. The Portfolio accounts for distributions received from REIT investments or from regulated investment companies as dividend income, realized gain, or return of capital based on information provided by the REIT or the investment company.

6. Class Allocations

All income earned and expenses incurred by the Portfolio are borne on a pro-rata basis by each outstanding class of shares, based on the proportionate interest in the Portfolio represented by the net assets of such class, except for class specific expenses which are allocated to the respective class. Expenses of the Fund are charged proportionately to each portfolio or based on other appropriate methods. Realized and unrealized gains and losses are allocated among the various share classes based on respective net assets.

7. Dividends and Distributions

Dividends and distributions to shareholders, if any, are recorded on the ex-dividend date. Income dividends and capital gains distributions are determined in accordance with federal tax regulations and may differ from those determined in accordance with U.S. GAAP. To the extent these differences are permanent, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require such reclassification.

NOTE B: Advisory Fee and Other Transactions with Affiliates

Under the terms of the investment advisory agreement, the Portfolio pays the Adviser an advisory fee at an annual rate of .45% of the first $2.5 billion, .425% of the next $2.5 billion and .40% in excess of $5 billion, of the Portfolio’s average daily net assets. The fee is accrued daily and paid monthly. Prior to May 2, 2022, the Portfolio paid the Adviser an advisory fee at an annual rate of .55% of the first $2.5 billion, .45% of the next $2.5 billion and .40% in excess of $5 billion, of the Portfolio’s average daily net assets. The Adviser has agreed to waive its fees and bear certain expenses to the extent necessary to limit total operating expenses on an annual basis (the “Expense Caps”) to .75% and 1.00% of daily average net assets for Class A and Class B shares, respectively. For the six months ended June 30, 2022, there was no such reimbursement.

Pursuant to the investment advisory agreement, the Portfolio may reimburse the Adviser for certain legal and accounting services provided to the Portfolio by the Adviser. For the six months ended June 30, 2022, the reimbursement for such services amounted to $42,086.

The Portfolio compensates AllianceBernstein Investor Services, Inc. (“ABIS”), a wholly-owned subsidiary of the Adviser, under a Transfer Agency Agreement for providing personnel and facilities to perform transfer agency services for the Portfolio. Such compensation retained by ABIS amounted to $873 for the six months ended June 30, 2022.

13

The Portfolio may invest in AB Government Money Market Portfolio (the “Government Money Market Portfolio”) which has a contractual annual advisory fee rate of .20% of the portfolio’s average daily net assets and bears its own expenses. The Adviser has contractually agreed to waive .10% of the advisory fee of Government Money Market Portfolio (resulting in a net advisory fee of .10%) until August 31, 2023. In connection with the investment by the Portfolio in Government Money Market Portfolio, the Adviser has contractually agreed to waive its advisory fee from the Portfolio in an amount equal to the Portfolio’s pro rata share of the effective advisory fee of Government Money Market Portfolio, as borne indirectly by the Portfolio as an acquired fund fee and expense. For the six months ended June 30, 2022, such waiver amounted to $3,140.

In connection with the Portfolio’s investments in other AB mutual funds, the Adviser has contractually agreed to waive fees and/or reimburse the expenses payable to the Adviser by the Portfolio in an amount equal to the Portfolio’s pro rata share of the effective advisory fees of AB mutual funds, as paid by the Portfolio as an acquired fund fee and expense. These fee waivers and/or expense reimbursements will remain in effect until December 31, 2022. For the six months ended June 30, 2022, such waivers and/or reimbursements amounted to $144,425.

A summary of the Portfolio’s transactions in AB mutual funds for the six months ended June 30, 2022 is as follows:

During the year ended December 31, 2021, the Adviser reimbursed the Portfolio $72 for trading losses incurred due to a trade entry error.

NOTE C: Distribution Plan

The Portfolio has adopted a Distribution Plan (the “Plan”) for Class B shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the Plan, the Portfolio pays distribution and servicing fees to AllianceBernstein Investments, Inc. (the “Distributor”), a wholly-owned subsidiary of the Adviser, at an annual rate of up to .50% of the Portfolio’s average daily net assets attributable to Class B shares. The fees are accrued daily and paid monthly. The Board currently limits payments under the Plan to .25% of the Portfolio’s average daily net assets attributable to Class B shares. The Plan provides that the Distributor will use such payments in their entirety for distribution assistance and promotional activities.    

14

The Portfolio is not obligated under the Plan to pay any distribution and servicing fees in excess of the amounts set forth above. The purpose of the payments to the Distributor under the Plan is to compensate the Distributor for its distribution services with respect to the sale of the Portfolio’s Class B shares. Since the Distributor’s compensation is not directly tied to its expenses, the amount of compensation received by it under the Plan during any year may be more or less than its actual expenses. For this reason, the Plan is characterized by the staff of the Securities and Exchange Commission as being of the “compensation” variety.

In the event that the Plan is terminated or not continued, no distribution or servicing fees (other than current amounts accrued but not yet paid) would be owed by the Portfolio to the Distributor.

The Plan also provides that the Adviser may use its own resources to finance the distribution of the Portfolio’s shares.

NOTE D: Investment Transactions

Purchases and sales of investment securities (excluding short-term investments) for the six months ended June 30, 2022 were as follows:

The cost of investments for federal income tax purposes was substantially the same as the cost for financial reporting purposes. Accordingly, gross unrealized appreciation and unrealized depreciation are as follows:

1. Derivative Financial Instruments

The Portfolio may use derivatives in an effort to earn income and enhance returns, to replace more traditional direct investments, to obtain exposure to otherwise inaccessible markets (collectively, “investment purposes”), or to hedge or adjust the risk profile of its portfolio.

The principal types of derivatives utilized by the Portfolio, as well as the methods in which they may be used are:

The Portfolio may buy or sell futures for investment purposes or for the purpose of hedging its portfolio against adverse effects of potential movements in the market. The Portfolio bears the market risk that arises from changes in the value of these instruments and the imperfect correlation between movements in the price of the futures and movements in the price of the assets, reference rates or indices which they are designed to track. Among other things, the Portfolio may purchase or sell futures for foreign currencies or options thereon for non-hedging purposes as a means of making direct investment in foreign currencies, as described below under “Currency Transactions”.

At the time the Portfolio enters into futures, the Portfolio deposits and maintains as collateral an initial margin with the broker, as required by the exchange on which the transaction is effected. Such amount is shown as cash collateral due from broker on the statement of assets and liabilities. Pursuant to the contract, the Portfolio agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded by the Portfolio as unrealized gains or losses. Risks may arise from the potential inability of a counterparty to meet the terms of the contract. The credit/counterparty risk for exchange-traded futures is generally less than privately negotiated futures, since the clearinghouse, which is the issuer or counterparty to each exchange-traded future, has robust risk mitigation standards, including the requirement to provide initial and variation margin. When the contract is closed, the Portfolio records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the time it was closed.

Use of long futures subjects the Portfolio to risk of loss in excess of the amounts shown on the statement of assets and liabilities, up to the notional value of the futures. Use of short futures subjects the Portfolio to unlimited risk of loss. Under some circumstances, futures exchanges may establish daily limits on the amount that the price of futures can vary from the previous day’s settlement price, which could effectively prevent liquidation of unfavorable positions.

15

During the six months ended June 30, 2022, the Portfolio held futures for hedging and non-hedging purposes.

The Portfolio may enter into forward currency exchange contracts in order to hedge its exposure to changes in foreign currency exchange rates on its foreign portfolio holdings, to hedge certain firm purchase and sale commitments denominated in foreign currencies and for non-hedging purposes as a means of making direct investments in foreign currencies, as described below under “Currency Transactions”.

A forward currency exchange contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated forward rate. The gain or loss arising from the difference between the original contract and the closing of such contract would be included in net realized gain or loss on forward currency exchange contracts. Fluctuations in the value of open forward currency exchange contracts are recorded for financial reporting purposes as unrealized appreciation and/or depreciation by the Portfolio. Risks may arise from the potential inability of a counterparty to meet the terms of a contract and from unanticipated movements in the value of a foreign currency relative to the U.S. dollar.

During the six months ended June 30, 2022, the Portfolio held forward currency exchange contracts for hedging and non-hedging purposes.

For hedging and investment purposes, the Portfolio may purchase and write (sell) put and call options on U.S. and foreign securities, including government securities, and foreign currencies that are traded on U.S. and foreign securities exchanges and over-the-counter markets. Among other things, the Portfolio may use options transactions for non-hedging purposes as a means of making direct investments in foreign currencies, as described below under “Currency Transactions” and may use options strategies involving the purchase and/or writing of various combinations of call and/or put options, for hedging and investment purposes.

The risk associated with purchasing an option is that the Portfolio pays a premium whether or not the option is exercised. Additionally, the Portfolio bears the risk of loss of the premium and change in market value should the counterparty not perform under the contract. If a put or call option purchased by the Portfolio were permitted to expire without being sold or exercised, its premium would represent a loss to the Portfolio. Put and call options purchased are accounted for in the same manner as portfolio securities. The cost of securities acquired through the exercise of call options is increased by premiums paid. The proceeds from securities sold through the exercise of put options are decreased by the premiums paid.

When the Portfolio writes an option, the premium received by the Portfolio is recorded as a liability and is subsequently adjusted to the current market value of the option written. The Portfolio’s maximum payment for written put options equates to the number of shares multiplied by the strike price. In certain circumstances maximum payout amounts may be partially offset by recovery values of the respective referenced assets and upfront premium received upon entering into the contract. Premiums received from written options which expire unexercised are recorded by the Portfolio on the expiration date as realized gains from options written. The difference between the premium received and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or if the premium received is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium received is added to the proceeds from the sale of the underlying security or currency in determining whether the Portfolio has realized a gain or loss. If a put option is exercised, the premium received reduces the cost basis of the security or currency purchased by the Portfolio. In writing an option, the Portfolio bears the market risk of an unfavorable change in the price of the security or currency underlying the written option. Exercise of an option written by the Portfolio could result in the Portfolio selling or buying a security or currency at a price different from the current market value.

During the six months ended June 30, 2022, the Portfolio held purchased options for hedging and non-hedging purposes.

The Portfolio may enter into swaps to hedge its exposure to interest rates, credit risk or currencies. The Portfolio may also enter into swaps for non-hedging purposes as a means of gaining market exposures, making direct investments in foreign currencies, as described below under “Currency Transactions.” A swap is an agreement that

16

obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. In addition, collateral may be pledged or received by the Portfolio in accordance with the terms of the respective swaps to provide value and recourse to the Portfolio or its counterparties in the event of default, bankruptcy or insolvency by one of the parties to the swap.

Risks may arise as a result of the failure of the counterparty to the swap to comply with the terms of the swap. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Portfolio, and/or the termination value at the end of the contract. Therefore, the Portfolio considers the creditworthiness of each counterparty to a swap in evaluating potential counterparty risk. This risk is mitigated by having a netting arrangement between the Portfolio and the counterparty and by the posting of collateral by the counterparty to the Portfolio to cover the Portfolio’s exposure to the counterparty. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities. The Portfolio accrues for the interim payments on swaps on a daily basis, with the net amount recorded within unrealized appreciation/depreciation of swaps on the statement of assets and liabilities, where applicable. Once the interim payments are settled in cash, the net amount is recorded as realized gain/(loss) on swaps on the statement of operations, in addition to any realized gain/(loss) recorded upon the termination of swaps. Upfront premiums paid or received for swaps are recognized as cost or proceeds on the statement of assets and liabilities and are amortized on a straight line basis over the life of the contract. Amortized upfront premiums are included in net realized gain/(loss) from swaps on the statement of operations. Fluctuations in the value of swaps are recorded as a component of net change in unrealized appreciation/depreciation of swaps on the statement of operations.

Certain standardized swaps, including certain interest rate swaps and credit default swaps, are (or soon will be) subject to mandatory central clearing. Cleared swaps are transacted through futures commission merchants (“FCMs”) that are members of central clearinghouses, with the clearinghouse serving as central counterparty, similar to transactions in futures contracts. Centralized clearing will be required for additional categories of swaps on a phased-in basis based on requirements published by the Securities and Exchange Commission and Commodity Futures Trading Commission.

At the time the Portfolio enters into a centrally cleared swap, the Portfolio deposits and maintains as collateral an initial margin with the broker, as required by the clearinghouse on which the transaction is effected. Such amount is shown as cash collateral due from broker on the statement of assets and liabilities. Pursuant to the contract, the Portfolio agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded by the Portfolio as unrealized gains or losses. Risks may arise from the potential inability of a counterparty to meet the terms of the contract. The credit/counterparty risk for centrally cleared swaps is generally less than non-centrally cleared swaps, since the clearinghouse, which is the issuer or counterparty to each centrally cleared swap, has robust risk mitigation standards, including the requirement to provide initial and variation margin. When the contract is closed, the Portfolio records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the time it was closed.

Interest Rate Swaps:

The Portfolio is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. Because the Portfolio holds fixed rate bonds, the value of these bonds may decrease if interest rates rise. To help hedge against this risk and to maintain its ability to generate income at prevailing market rates, the Portfolio may enter into interest rate swaps. Interest rate swaps are agreements between two parties to exchange cash flows based on a notional amount. The Portfolio may elect to pay a fixed rate and receive a floating rate, or, receive a fixed rate and pay a floating rate on a notional amount.

In addition, the Portfolio may also enter into interest rate swap transactions to preserve a return or spread on a particular investment or portion of its portfolio, or protecting against an increase in the price of securities the Portfolio anticipates purchasing at a later date. Interest rate swaps involve the exchange by a Portfolio with another party of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed

17

rate payments) computed based on a contractually-based principal (or “notional”) amount. Interest rate swaps are entered into on a net basis (i.e., the two payment streams are netted out, with the Portfolio receiving or paying, as the case may be, only the net amount of the two payments).

During the six months ended June 30, 2022, the Portfolio held interest rate swaps for hedging and non-hedging purposes.

Inflation (CPI) Swaps:

Inflation swap agreements are contracts in which one party agrees to pay the cumulative percentage increase in a price index (the Consumer Price Index with respect to CPI swaps) over the term of the swap (with some lag on the inflation index), and the other pays a compounded fixed rate. Inflation swaps may be used to protect the net asset value, or NAV, of a Portfolio against an unexpected change in the rate of inflation measured by an inflation index since the value of these agreements is expected to increase if there are unexpected inflation increases.

During the six months ended June 30, 2022, the Portfolio held inflation (CPI) swaps for hedging and non-hedging purposes.

Credit Default Swaps:

The Portfolio may enter into credit default swaps, including to manage its exposure to the market or certain sectors of the market, to reduce its risk exposure to defaults by corporate and sovereign issuers held by the Portfolio, or to create exposure to corporate or sovereign issuers to which it is not otherwise exposed. The Portfolio may purchase credit protection (“Buy Contract”) or provide credit protection (“Sale Contract”) on the referenced obligation of the credit default swap. During the term of the swap, the Portfolio receives/(pays) fixed payments from/(to) the respective counterparty, calculated at the agreed upon rate applied to the notional amount. If the Portfolio is a buyer/(seller) of protection and a credit event occurs, as defined under the terms of the swap, the Portfolio will either (i) receive from the seller/(pay to the buyer) of protection an amount equal to the notional amount of the swap (the “Maximum Payout Amount”) and deliver/(take delivery of) the referenced obligation or (ii) receive/(pay) a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation. In certain circumstances Maximum Payout Amounts may be partially offset by recovery values of the respective referenced obligations, upfront premium received upon entering into the agreement, or net amounts received from settlement of buy protection credit default swaps entered into by the Portfolio for the same referenced obligations with the same counterparty.

Credit default swaps may involve greater risks than if a Portfolio had invested in the referenced obligation directly. Credit default swaps are subject to general market risk, liquidity risk, counterparty risk and credit risk. If the Portfolio is a buyer of protection and no credit event occurs, it will lose the payments it made to its counterparty. If the Portfolio is a seller of protection and a credit event occurs, the value of the referenced obligation received by the Portfolio coupled with the periodic payments previously received, may be less than the Maximum Payout Amount it pays to the buyer, resulting in a net loss to the Portfolio.

Implied credit spreads over U.S. Treasuries of comparable maturity utilized in determining the market value of credit default swaps on issuers as of period end are disclosed in the portfolio of investments. The implied spreads serve as an indicator of the current status of the payment/performance risk and typically reflect the likelihood of default by the issuer of the referenced obligation. The implied credit spread of a particular reference obligation also reflects the cost of buying/selling protection and may reflect upfront payments required to be made to enter into the agreement. Widening credit spreads typically represent a deterioration of the referenced obligation’s credit soundness and greater likelihood of default or other credit event occurring as defined under the terms of the agreement. A credit spread identified as “Defaulted” indicates a credit event has occurred for the referenced obligation.

During the six months ended June 30, 2022, the Portfolio held credit default swaps for hedging and non-hedging purposes.

The Portfolio typically enters into International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreement”) with its OTC derivative contract counterparties in order to, among other things, reduce its credit risk to OTC counterparties. ISDA Master Agreements include provisions for general obligations, representations, collateral and events of default or termination. Under an ISDA Master Agreement, the Portfolio typically may offset with the OTC counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single

18

net payment (close-out netting) in the event of default or termination. In the event of a default by an OTC counterparty, the return of collateral with market value in excess of the Portfolio’s net liability, held by the defaulting party, may be delayed or denied.

The Portfolio’s ISDA Master Agreements may contain provisions for early termination of OTC derivative transactions in the event the net assets of the Portfolio decline below specific levels (“net asset contingent features”). If these levels are triggered, the Portfolio’s OTC counterparty has the right to terminate such transaction and require the Portfolio to pay or receive a settlement amount in connection with the terminated transaction. If OTC derivatives were held at period end, please refer to netting arrangements by the OTC counterparty table below for additional details.

During the six months ended June 30, 2022, the Portfolio had entered into the following derivatives:

For financial reporting purposes, the Portfolio does not offset derivative assets and derivative liabilities that are subject to netting arrangements in the statement of assets and liabilities.

All OTC derivatives held at period end were subject to netting arrangements. The following table presents the Portfolio’s derivative assets and liabilities by OTC counterparty net of amounts available for offset under ISDA Master Agreements (“MA”) and net of the related collateral received/pledged by the Portfolio as of June 30, 2022. Exchange-traded derivatives and centrally cleared swaps are not subject to netting arrangements and as such are excluded from the table.

2. Currency Transactions

The Portfolio may invest in non-U.S. Dollar-denominated securities on a currency hedged or unhedged basis. The Portfolio may seek investment opportunities by taking long or short positions in currencies through the use of currency-related derivatives, including forward currency exchange contracts, futures and options on futures, swaps, and other options. The Portfolio may enter into transactions for investment opportunities when it anticipates that a foreign currency will appreciate or depreciate in value but securities denominated in that currency are not held by the Portfolio and do not present attractive investment opportunities. Such transactions may also be used when the Adviser believes that it may be more efficient than a direct investment in a foreign currency-denominated security. The Portfolio may also conduct currency exchange contracts on a spot basis (i.e., for cash at the spot rate prevailing in the currency exchange market for buying or selling currencies).

3. TBA and Dollar Rolls

The Portfolio may invest in TBA mortgage-backed securities. A TBA, or “To Be Announced”, trade represents a contract for the purchase or sale of mortgage-backed securities to be delivered at a future agree-upon date; however, the specific mortgage pool numbers or the number of pools that will be delivered to fulfill the trade obligation or terms of the contract are unknown at the time of the trade. Mortgage pools (including fixed-rate or variable-rate mortgages) guaranteed by the Government National Mortgage Association, or GNMA, the Federal National Mortgage Association, or FNMA, or the Federal Home Loan Mortgage Corporation, or FHLMC, are subsequently allocated to the TBA transactions.

The Portfolio may enter into certain TBA transactions known as dollar rolls. Dollar rolls involve sales by the Portfolio of securities for delivery in the current month and the Portfolio’s simultaneously contracting to repurchase substantially similar (same type and coupon) securities on a specified future date. During the roll period, the Portfolio forgoes principal and interest paid on the securities. The Portfolio is compensated by the difference between the current sales price and the lower forward price for the future purchase (often referred to as the “drop”) as well as by the interest earned on the cash proceeds of the initial sale. Dollar rolls involve the risk that the market value of the securities the Portfolio is obligated to repurchase under the agreement may decline below the repurchase price. Dollar rolls are speculative techniques. For the six months ended June 30, 2022, the Portfolio earned drop income of $12,275 which is included in interest income in the accompanying statement of operations.

NOTE E: Securities Lending

The Portfolio may enter into securities lending transactions. Under the Portfolio’s securities lending program, all loans of securities will be collateralized continually by cash collateral and/or non-cash collateral. Non-cash collateral will include only securities issued or guaranteed by the U.S. government or its agencies or instrumentalities. The Portfolio cannot sell or repledge any non-cash collateral, such collateral will not be reflected in the portfolio of investments. If a loan is collateralized by cash, the Portfolio will be compensated for the loan from a portion of the net return from the income earned on cash collateral after a rebate is paid to the borrower (in some cases, this rebate may be a “negative rebate” or fee paid by the borrower to the Portfolio in connection with the loan), and payments are made for fees of the securities lending agent and for certain other administrative expenses. If the Portfolio receives non-cash collateral, the Portfolio will receive a fee from the borrower generally equal to a negotiated percentage of the market value of the loaned securities. The Portfolio will have the right to call a loan and obtain the securities loaned at any time on notice to the borrower within the normal and customary settlement time for the securities. While the securities are on loan, the borrower is obligated to pay the Portfolio amounts equal to any dividend income or other distributions from the securities; however, these distributions will not be afforded the same preferential tax treatment as qualified dividends. The Portfolio will not be able to exercise voting rights with respect to any securities during the existence of a loan, but will have the right to regain ownership of loaned securities in order to exercise voting or other ownership rights. Collateral received and securities loaned are marked to market daily to ensure that the securities loaned are secured by collateral. The lending agent currently invests the cash collateral received in Government Money Market Portfolio, an eligible money market vehicle, in accordance with the investment restrictions of the Portfolio, and as approved by the Board. The collateral received on securities loaned is recorded as an asset as well as a corresponding liability in the statement of assets and liabilities. The collateral will be adjusted the next business day to maintain the required collateral amount. The amounts of securities lending income from the borrowers and Government Money Market Portfolio are reflected in the statement of operations. When the Portfolio earns net securities lending income from Government Money Market Portfolio, the income is inclusive of a rebate expense paid to the borrower. In connection with the cash collateral investment by the Portfolio in Government Money Market Portfolio, the Adviser has agreed to waive a portion of the Portfolio’s share of the advisory fees of Government Money Market Portfolio, as borne indirectly by the Portfolio as an acquired fund fee and expense. When the Portfolio lends securities, its investment performance will continue to reflect

21

changes in the value of the securities loaned. A principal risk of lending portfolio securities is that the borrower may fail to return the loaned securities upon termination of the loan and that the collateral will not be sufficient to replace the loaned securities. The lending agent has agreed to indemnify the Portfolio in the case of default of any securities borrower.

A summary of the Portfolio’s transactions surrounding securities lending for the six months ended June 30, 2022 is as follows:
