Other securities are primarily composed of FHLB stock and FRB stock (which are carried at cost) and mutual funds and other marketable equity securities (which are carried at fair value, with changes in fair value recognized in other noninterest income). Other securities that are carried at cost are reviewed at least annually for impairment, with valuation adjustments recognized in other noninterest income.
