At March 31, 2016, there were eight available-for-sale investment securities in the less-than-twelve-month category and thirteen available-for-sale investment securities in the twelve-month-or-more category. The unrealized losses on the mortgage-backed securities are guaranteed by government-sponsored entities and primarily relate to changes in market interest rates. All amounts are expected to be recovered when market prices recover or at maturity. The unrealized losses on the equity securities reflect decreases in market price and adverse changes in foreign currency exchange rates. Customers evaluated the financial condition and capital strength of the issuer of these securities and concluded that the decline in fair value was temporary and estimated the value could reasonably recover by way of increases in market price or positive changes in foreign currency exchange rates. Customers intends to hold these securities for the foreseeable future and does not intend to sell the securities before the price recovers. Customers considers it more likely than not that it will not be required to sell the securities. Accordingly, Customers concluded that the securities are not other-than-temporarily impaired as of March 31, 2016.

At March 31, 2016 and December 31, 2015, Customers Bank had pledged investment securities aggregating $286.3 million and $299.8 million fair value, respectively, as collateral against its borrowings primarily with the FHLB and an unused line of credit with another financial institution. These counterparties do not have the ability to sell or repledge these securities.
