The gross unrealized losses reported for residential mortgage-backed securities relate to investment securities issued by U.S. government sponsored entities such as Federal National Mortgage Association and Federal Home Loan Mortgage Corporation, U.S. government agencies such as Government National Mortgage Association, and non-agencies. The total gross unrealized losses, shown in the tables above, were primarily attributable to changes in interest rates and levels of market liquidity, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities.

The Company does not intend to sell the investment securities that are in an unrealized loss position until recovery of unrealized losses (which may be until maturity), and it is not more-likely-than not that the Company will be required to sell the investment securities before recovery of their amortized cost basis, which may be at maturity. Accordingly, as of December 31, 2017, and December 31, 2016, management believes the unrealized losses detailed in the tables above are not other-than-temporary.

The Company did not recognize any net credit impairment charge to earnings on investment securities in 2017 or 2016.

The amortized cost and estimated fair value of debt securities by contractual maturity are shown in the following table. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Mortgage-backed securities are shown separately since they are not due at a single maturity date.

Investment in Small Business Investment Companies

The Company has equity investments in small business investment companies (“SBIC”) established for the purpose of providing financing to small businesses in market areas served by the Company. As of both December 31, 2017 and December 31, 2016, these investments totaled $1.7 million, and were included in other assets on the Company’s Consolidated Statements of Condition. These investments are accounted for either under the cost method or the equity method of accounting. As of December 31, 2017, the Company reviewed these investments and determined that there was no impairment.

Federal Home Loan Bank Stock

The Company also holds non-marketable Federal Home Loan Bank New York (“FHLBNY”) stock, non-marketable Federal Home Loan Bank Pittsburgh (“FHLBPITT”) stock and non-marketable Atlantic Community Bankers Bank (“ACBB”) stock, all of which are required to be held for regulatory purposes and for borrowing availability. The required investment in FHLB stock is tied to the Company’s borrowing levels with the FHLB. Holdings of FHLBNY stock, FHLBPITT stock and ACBB stock totaled $34.2 million, $16.2 million and $95,000 at December 31, 2017, respectively. These securities are carried at par, which is also cost. The FHLBNY and FHLBPITT continue to pay dividends and repurchase stock. As such, the Company has not recognized any impairment on its holdings of FHLBNY and FHLBPITT stock.
