Reverse Repurchase Agreements	Reverse Repurchase Agreements The Account periodically enters into reverse repurchase agreements (or "repos") with third parties. Repos are transactions in which the Account purchases securities with a contractual obligation to resell them at a specific date and price, generally overnight or with a short maturity (e.g., one to seven days). The Account enters into these repos pursuant to an existing agreement with State Street Bank & Trust Company (“State Street”) as a part of the liquid, fixed-income investment portion of the Account’s portfolio. The Account’s repo transactions include cash collateral received on securities loaned, certain overdraft credit agreements, and securities purchased under resale agreements. The securities underlying these repo transactions consist primarily of U.S. government and agency securities, which are monitored for market value daily. Under the Account’s existing reverse repurchase agreement with State Street, the Account generally has a right to obtain additional collateral or return excess collateral as market values fluctuate and to sell or repledge securities received as collateral. Repos have the risk that the counterparty to the transaction fails to pay the agreed upon resale price on the delivery date and the value of the collateral after the costs of disposing the collateral and any delay in foreclosing is less than the repurchase price. As of March 31, 2026, the aggregate fair value of securities held by the Account under the repos was $367.5 million, which represents less than 1.6% of the Account’s total net assets as of March 31, 2026.
