The weighted
 
average yield
 
on debt
 
securities available-for-sale
 
is based
 
on amortized
 
cost; therefore,
 
it
 
does not
 
give
 
effect to
changes in fair value.

such
 
as
 
mortgage-backed
 
securities
 
and
 
collateralized
 
mortgage
obligations, are classified
 
in the period
 
of final contractual
 
maturity. The
 
expected maturities of
 
collateralized mortgage obligations,
mortgage-backed securities and certain other securities may
 
differ from their contractual maturities
 
because they may be subject to
prepayments or may be called by the issuer.
At March 31, 2026, the Corporation did not intend
 
to sell or believed it was more
 
likely than not that it would be
 
required to sell debt
securities classified as available-for-sale. There were
 
no debt securities sold during the quarters ended
 
March 31, 2026 and 2025.

Debt securities available-for-sale
 
in a continuous

for
 
less than twelve
 
months of $
11.8
 
billion as of
 
March
31, 2026, compared to $
1.2
 
billion on December 31, 2025, primarily driven by an increase market rates, which resulted in a
 
decline
in the fair value of fixed-rate securities including U.S.
 
Treasury securities and mortgage-backed securities.
 
As of March 31, 2026, the portfolio of available-for-sale debt securities reflects gross unrealized losses of $
0.9
 
billion (December 31,
2025
 
-
 
$
0.9
 
billion),
 
driven
 
mainly
 
by
 
mortgage-backed
 
securities,
 
impacted
 
by
 
the
 
higher-interest
 
rate
 
environment
 
and
 
the
portfolio’s longer
 
duration. The
 
portfolio of
 
available-for-sale debt securities
 
is comprised mainly
 
of U.S
 
Treasuries and
 
obligations
from
 
the
 
U.S.
 
Government,
 
its
 
agencies
 
or
 
government
 
sponsored
 
entities,
 
including
 
Federal
 
National
 
Mortgage
 
Association
(“FNMA”), Federal Home Loan Mortgage Corporation (“FHLMC”) and Government National Mortgage Association (“GNMA”). These
securities carry
 
an explicit
 
or implicit
 
guarantee from the
 
U.S. Government,
 
are highly
 
rated by
 
major rating
 
agencies, and
 
have a
long history of no credit losses. Accordingly, the Corporation applies a zero-credit
 
loss assumption.
