Publicly offered non-agency residential mortgage-backed securities (MBS) that represent an unsubordinated interest in cash flows from pools of 1-4 family residential properties are eligible collateral for FHLB advances. Subordinate tranches may be eligible as Category 5, Other Real Estate Related Collateral. Non-agency residential MBS collateral is subject to individual review and acceptance by the Bank.
