Please note that the changes below may impact your variable annuity and/or variable life product(s).

Unless otherwise noted, all changes are effective immediately.

Effective June 30, 2025, for the JNL Multi-Manager Mid Cap Fund, please delete all references to and information for Darren Schryer.


Effective July 11, 2025, for the JNL Multi-Manager Small Cap Growth Fund, please delete all references to and information for Trevor Martin.

Effective June 20, 2025, in the section, “Non-Fundamental Policies and Risks Applicable to the AFIS Master Funds and the JNL/American Funds Feeder Funds,” please delete “Forward Commitment, When Issued and Delayed Delivery Transactions” in the entirety and replace with the following:

Forward Commitment, When Issued and Delayed Delivery Transactions. The AFIS Master fund may enter into commitments to purchase or sell securities at a future date. When the AFIS Master Fund agrees to purchase such securities, it assumes the risk of any decline in value of the security from the date of the agreement, and when the AFIS Master Fund agrees to sell such securities, it assumes the risk of any increase in value of the security. If the other party to such a transaction fails to deliver or pay for the securities, the AFIS Master Fund could miss a favorable price or yield opportunity, or could experience a loss.

The AFIS Master Fund may roll such transactions in lieu of taking physical delivery of the contract’s underlying assets on the settlement date. When rolling the purchase of these types of transactions, the AFIS Master Fund sells mortgage-backed securities for delivery in the current month and simultaneously contracts to repurchase substantially similar (same type, coupon, and maturity) securities on a specified future date, at a pre-determined price. When rolling the sale of these types of transactions, the AFIS Master Fund purchases mortgage-backed securities for delivery in the current month and simultaneously contracts to sell substantially similar (same type, coupon, and maturity) securities on a specified future date, at a pre-determined price.

When rolling these types of transactions, during the period between the initial sale (or purchase) and subsequent repurchase (or sale) (the “roll period”), the AFIS Master Fund forgoes principal and interest paid on the mortgage-backed securities. The AFIS Master Fund is compensated by the price differential between the original and new contracts (often referred to as the “drop”), if any, as well as by the interest earned on the cash proceeds of any sales. The AFIS Master Fund also takes the risk that market prices or characteristics of the underlying mortgage-backed securities may move unfavorably between the original and new contracts. The AFIS Master Fund could suffer a loss if the contracting party fails to perform the future transaction and the AFIS Master Fund is therefore unable to buy or sell back the mortgage-backed securities it initially either sold or purchased, respectively. These transactions are accounted for as purchase and sale transactions, which contribute to the AFIS Master Fund’s portfolio turnover rate.

With TBA transactions, the particular securities (i.e., specified mortgage pools) to be delivered or received are not identified at the trade date, but are “to be announced” at a later settlement date. However, securities to be delivered must meet specified criteria, including face value, coupon rate and maturity, and be within industry-accepted “good delivery” standards. These transactions could lead to the fund being in a leveraged position (because it may have an amount greater than its net assets subject to market risk) and may have to sell securities at inopportune times or prices. As a result, increases and decreases in the value of the AFIS Master Fund’s portfolio may be magnified. Should market values of the AFIS Master Fund’s portfolio securities decline while the AFIS Master Fund is in a leveraged position, greater depreciation of its net assets would likely occur than if it were not in such a position. After a transaction is entered into, the AFIS Master Fund may still dispose of or renegotiate the transaction. Additionally, prior to receiving delivery of securities as part of a transaction, the AFIS Master Fund may sell such securities.

When the AFIS Master Fund enters into a TBA commitment for the sale of mortgage-backed securities for a fixed price, with payment and delivery on an agreed upon future settlement date (which may be referred to as having a short position in such TBA securities), the AFIS Master Fund may or may not hold the types of mortgage-backed securities required to be delivered. To the extent the AFIS Master Fund has sold such a security on a when-issued, delayed delivery, or forward commitment basis, the AFIS Master Fund would not participate in future gains or losses with respect to the security if the AFIS Master Fund holds such security. If the other party to a transaction fails to pay for the securities, the AFIS Master Fund could suffer a loss. Additionally, when selling a security on a when-issued, delayed delivery or forward commitment basis without owning the security, the AFIS Master Fund will incur a loss if the security’s price appreciates in value such that the security’s price is above the agreed-upon price on the settlement date.

Under the SEC’s rule applicable to the AFIS Master Fund’s use of derivatives, when issued, forward-settling and nonstandard settlement cycle securities, as well as TBAs and roll transactions, will be treated as derivatives unless the AFIS Master Fund intends to physically settle these transactions and the transactions will settle within 35 days of their respective trade dates.
