Short-term Borrowings

We have certain facilities in place to enable us to access short-term borrowings on a secured and unsecured basis. Our secured facilities include collateral pledged to the FHLB of San Francisco and the discount window at the FRB (using both fixed income securities and loans as collateral). Our unsecured facility consists of our uncommitted federal funds lines. As of June 30, 2019, collateral pledged to the FHLB of San Francisco was comprised primarily of fixed income investment securities and loans and had a carrying value of $4.6 billion, of which $4.1 billion was available to support additional borrowings. As of June 30, 2019, collateral pledged to the discount window at the FRB was comprised of fixed income investment securities and had a carrying value of $0.6 billion, all of which was unused and available to support additional borrowings. Our total unused and available borrowing capacity for our uncommitted federal funds lines totaled $1.9 billion at June 30, 2019. Our total unused and available borrowing capacity under our master repurchase agreements with various financial institutions totaled $3.3 billion at June 30, 2019.
