At December 31, 2025, our banking subsidiaries had pledged HTM securities as collateral under repurchase agreements with external financial institutions. HTM securities pledged were U.S. agency mortgage-backed securities with an aggregate amortized cost of $1.3 billion, all of which may be sold, repledged, or otherwise used by the counterparties. See Notes 2, 13, and 17 for additional information on these repurchase agreements.

At December 31, 2025, the Company had pledged AFS securities consisting of U.S. Treasury securities with an aggregate fair value of $281 million as initial margin on interest rate swaps (see Notes 16 and 17). All of Schwab’s interest rate swaps are cleared through CCPs which require the Company to post initial margin as collateral against potential losses. Initial margin is posted through FCMs which serve as the intermediary between the CCPs and Schwab. The FCM agreements governing our swaps allow for securities pledged as initial margin to be sold, repledged, or otherwise used by the FCM.

AFS investment securities with unrealized losses, aggregated by category and period of continuous unrealized loss, are as follows:

(1) Amounts of unrealized losses less than 12 months were less than $500 thousand.

(2) For purposes of this table, unrealized losses on AFS securities excludes the unallocated PLM fair value hedge basis adjustments of $2 million and $(47) million at December 31, 2025 and 2024, respectively.

At December 31, 2025, substantially all rated securities in the investment portfolios were investment grade. U.S. agency mortgage-backed securities do not have explicit credit ratings; however, management considers these to be of the highest credit quality and rating given the guarantee of principal and interest by the U.S. government or U.S. government-sponsored enterprises.

For a description of management’s quarterly evaluation of AFS securities in unrealized loss positions, see Note 2. No amounts were recognized as credit loss expense andno securities were written down to fair value through earnings for the years ended December 31, 2025 and 2024. None of the Company’s AFS securities held as of December 31, 2025 and 2024 had an allowance for credit losses. HTM securities as of December 31, 2025 were U.S. agency mortgage-backed securities and U.S. Treasury securities, and as of December 31, 2024 all HTM securities were U.S. agency mortgage-backed securities. At both December 31, 2025 and 2024, HTM securities hadno allowance for credit losses because expected nonpayment of the amortized cost basis is zero.

The Company had $386 million and $455 million of accrued interest for AFS and HTM securities as of December 31, 2025 and 2024, respectively. These amounts are excluded from the amortized cost basis and fair market value of AFS and HTM securities
