Resale and Repurchase Agreements [Abstract] |
Securities Purchased under Resale Agreements and Sold under Repurchase Agreements | Securities Purchased under Resale Agreements and Sold under Repurchase Agreements Resale Agreements Resale agreements are recorded at the values at which the securities were acquired. The market values of the underlying securities collateralizing the related receivable of the resale agreements, including accrued interest, are monitored. Additional collateral may be requested by the Company from the counterparty when deemed appropriate. Gross resale agreements were $1.45 billion as of both March 31, 2018 and December 31, 2017. The weighted-average interest rates were 2.55% and 2.43% as of March 31, 2018 and December 31, 2017, respectively. Repurchase Agreements Long-term repurchase agreements are accounted for as collateralized financing transactions and recorded at the values at which the securities are sold. The collateral for the repurchase agreements is primarily comprised of U.S. Treasury securities, U.S. government agency and U.S. government sponsored enterprise mortgage-backed securities, and U.S. government agency and U.S. government sponsored enterprise debt securities. The Company may have to provide additional collateral for the repurchase agreements, as necessary. Gross repurchase agreements were $450.0 million as of both March 31, 2018 and December 31, 2017. The weighted-average interest rates were 4.07% and 3.65% as of March 31, 2018 and December 31, 2017, respectively. Balance Sheet Offsetting The Company’s resale and repurchase agreements are transacted under legally enforceable master repurchase agreements that provide the Company, in the event of default by the counterparty, the right to liquidate securities held and to offset receivables and payables with the same counterparty. The Company nets resale and repurchase transactions with the same counterparty on the Consolidated Balance Sheet when it has a legally enforceable master netting agreement and the transactions are eligible for netting under ASC 210-20-45-11. Collateral accepted includes securities that are not recognized on the Consolidated Balance Sheet. Collateral pledged consists of securities that are not netted on the Consolidated Balance Sheet against the related collateralized liability. Collateral accepted or pledged in resale and repurchase agreements with other financial institutions may also be sold or re-pledged by the secured party, but is usually delivered to and held by the third party trustees. The collateral amounts received/pledged are limited for presentation purposes to the related recognized asset/liability balance for each counterparty, and accordingly, do not include excess collateral received/pledged. The following tables present the resale and repurchase agreements included on the Consolidated Balance Sheet as of March 31, 2018 and December 31, 2017:
