The following table shows debt investment securities by stated maturity. Investment securities backed by mortgages have expected maturities that differ from contractual maturities because borrowers have the right to call or prepay and, therefore, these debt securities are classified separately with no specific maturity date:

At June 30, 2018, there were sixty-four available-for-sale debt investment securities in the less-than-twelve-month category and sixteen available-for-sale debt 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. The unrealized losses on the corporate notes relate to securities with no company specific concentration. The unrealized losses were due to an upward shift in interest rates that resulted in a negative impact on the respective notes pricing. All amounts related to the mortgage-backed securities and the corporate notes are expected to be recovered when market prices recover or at maturity. Customers does not intend to sell these securities and it is not more likely than not that Customers will be required to sell the securities before recovery of the amortized cost basis.

During the three and six month period ended June 30, 2017, Customers recorded other-than-temporary impairment losses of $2.9 million and $4.6 million, respectively, related to its equity holdings in Religare Enterprises Ltd. ("Religare") for the full amount of the decline in fair value from the cost basis established at December 31, 2016 through June 30, 2017 because Customers no longer had the intent to hold these securities until a recovery in fair value. At December 31, 2017, the fair value of the Religare equity securities was $3.4 million which resulted in an unrealized gain of $1.0 million being recognized in accumulated other comprehensive income with no adjustment for deferred taxes as Customers currently does not have a tax strategy in place capable of generating sufficient capital gains to utilize any capital losses resulting from the Religare investment.

As described in NOTE 3 - SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION, the adoption of ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, on January 1, 2018 resulted in a cumulative effect adjustment to Customers' consolidated balance sheet with a $1.0 million reduction in accumulated other comprehensive income and a corresponding increase in retained earnings related to the December 31, 2017 unrealized gain on the Religare equity securities. In accordance with the new accounting guidance, changes in the fair value of the Religare equity securities since adoption were recorded directly in earnings, which resulted in an unrealized loss of $0.3 million being recognized in other non-interest income in the accompanying consolidated statements of income for the three and six months ended June 30, 2018, respectively.

At June 30, 2018 and December 31, 2017, Customers Bank had pledged investment securities aggregating $685.0 million and $16.9 million in 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.
