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 June 30, 2016, 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. Treasury securities) at June 30, 2016 totaled $1.8 billion, of which $1.2 billion was unused and available to support additional borrowings. The market value of collateral pledged at the discount window of the Federal Reserve Bank at June 30, 2016 totaled $0.9 billion, all of which was unused and available to support additional borrowings.
