(1)
Represents cash collateral received from certain counterparties in relation to market value exposures of derivative contracts in our favor, primarily for our interest rate swap agreement related to our 6.05% Subordinated Notes.
(2)
At September 30, 2014 and December 31, 2013, included in the carrying value of our 6.05% Subordinated Notes was an interest rate swap valued at $5.0 million and $6.5 million, respectively, related to hedge accounting associated with the notes.
Interest expense related to long-term debt was $5.8 million and $17.4 million for the three and nine months ended September 30, 2014, and $5.7 million and $17.4 million for the three and nine months ended September 30, 2013. Interest expense is net of the hedge accounting impact from our interest rate swap agreement related to our 6.05% Subordinated Notes. The weighted average interest rate associated with our short-term borrowings as of September 30, 2014 was 0.07 percent.
Available Lines of Credit
We have certain facilities in place to enable us to access short-term borrowings on a secured (using high-quality fixed income securities as collateral) and an unsecured basis. These include repurchase agreements and uncommitted federal funds lines with various financial institutions. As of September 30, 2014, 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 Federal Reserve Bank. The market value of collateral pledged to the FHLB of San Francisco (comprised primarily of U.S. agency debentures and mortgage securities) at September 30, 2014 totaled $1.2 billion, all of which was unused and available to support additional borrowings. The market value of collateral pledged at the discount window of the Federal Reserve Bank at September 30, 2014 totaled $517 million, all of which was unused and available to support additional borrowings.
