The decline in fair value for the debt securities that had
been in a continuous loss position for 12 months or more at
December 31, 2006, was largely due to changes in market
interest rates and not due to the credit quality of the securities.
We believe that the principal and interest on these securities
are fully collectible and we have the intent and ability to
retain our investment for a period of time to allow for any
anticipated recovery in market value. We have reviewed
these securities in accordance with our policy and do not
consider them to be other-than-temporarily impaired.
Securities pledged where the secured party has the right to
sell or repledge totaled $5.3 billion at both December 31, 2006
and 2005. Securities pledged where the secured party does
not have the right to sell or repledge totaled $29.3 billion
at December 31, 2006, and $24.3 billion at December 31,
2005, primarily to secure trust and public deposits and for
other purposes as required or permitted by law. We have
accepted collateral in the form of securities that we have the
right to sell or repledge of $1.8 billion at December 31, 2006,
and $3.4 billion at December 31, 2005, of which we sold or
repledged $1.4 billion and $2.3 billion, respectively.
The following table shows the remaining contractual
principal maturities and contractual yields of debt securities
available for sale. The remaining contractual principal
maturities for mortgage-backed securities were allocated
assuming no prepayments. Remaining expected maturities
will differ from contractual maturities because borrowers
may have the right to prepay obligations before the underlying
mortgages mature.
The following table shows the realized net gains on
the sales of securities from the securities available for sale
portfolio, including marketable equity securities.
