(2)
At March 31, 2013 and December 31, 2012, included in the carrying value of our 6.05% Subordinated Notes were $8.5 million and $9.0 million, respectively, related to hedge accounting associated with the notes.
Interest expense related to short-term borrowings and long-term debt was $5.8 million and $6.4 million for the three months ended March 31, 2013, and 2012, respectively. Interest expense is net of the hedge accounting impact from our interest rate swap agreements related to our 5.70% Senior Notes and 6.05% Subordinated Notes. The weighted average interest rate associated with our short-term borrowings as of March 31, 2013 was 0.12 percent.
Available Lines of Credit
We have certain facilities in place to enable us to access short-term borrowings on a secured (using available-for-sale securities as collateral) and an unsecured basis. These include repurchase agreements and uncommitted federal funds lines with various financial institutions. As of March 31, 2013, we did not borrow against our uncommitted federal funds lines. We also pledge securities to the FHLB of San Francisco and the discount window at the FRB. The market value of collateral pledged to the FHLB of San Francisco (comprised primarily of U.S. agency debentures) at March 31, 2013 totaled $1.5 billion, all of which was unused and available to support additional borrowings. The market value of collateral pledged at the discount window of the FRB at March 31, 2013 totaled $673 million, all of which was unused and available to support additional borrowings.
