Contractual Maturity Distribution Of Debt Securities

The following table summarizes the amortized cost and fair values of investment securities by contractual maturity. Securities with multiple maturity dates are classified in the period of final maturity. The actual cash flows of mortgage-backed securities may differ as borrowers of the underlying loans may exercise prepayment options. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

(in millions)
March 31, 2025			Amortized Cost						Fair Value
Contractual maturity
One year or less			$	308					$	308
After one year through five years			1,298						1,287
After five years through ten years			5,101						4,655
After ten years			10,934						8,852
Total investment securities			$	17,641					$	15,102
