Note 3 – Securities

Investment Portfolio Management

Our investment portfolio serves the liquidity needs and income objectives of the Company. While the portfolio serves as an important component of the overall liquidity management at the Bank, portions of the portfolio also serve as income producing assets. The size and composition of the portfolio reflects liquidity needs, loan demand and interest income objectives. Portfolio size and composition will be adjusted from time to time. While a significant portion of the portfolio consists of readily marketable securities to address liquidity, other parts of the portfolio may reflect funds invested pending future loan demand or to maximize interest income without undue interest rate risk.

Investments are comprised of debt securities and non-marketable equity investments. Securities available-for-sale are carried at fair value. Unrealized gains and losses, net of tax, on securities available-for-sale are reported as a separate component of equity. This balance sheet component changes as interest rates and market conditions change. Unrealized gains and losses are not included in the calculation of regulatory capital.

FHLBC and FRBC stock are considered nonmarketable equity investments. FHLBC stock was recorded at $3.8 million at March 31, 2017, and $3.1 million at December 31, 2016, and is necessary to maintain access to FHLBC advances, which are utilized as a component to meet the Bank’s daily funding needs. FRBC stock was recorded at $4.8 million at March 31, 2017, and December 31, 2016.

The following table summarizes the amortized cost and fair value of the securities portfolio at March 31, 2017, and December 31, 2016, and the corresponding amounts of gross unrealized gains and losses (in thousands):

At March 31, 2017, the Company’s investments include $119.0 million of asset-backed securities that are backed by student loans originated under the Federal Family Education Loan program (“FFEL”). Under the FFEL, private lenders made federally guaranteed student loans to parents and students and packaged and sold them as asset-backed securities. While the program was modified several times before elimination in 2010, not less than 97% of the outstanding principal amount of the loans made under FFEL are guaranteed by the U.S. Department of Education. In addition to the U.S. Department of Education guarantee, total added credit enhancement in the form of overcollateralization and/or subordination amounted to $13.0 million, or 10.01%, of outstanding principal.

Recognition of other-than-temporary impairment was not necessary in the three months ending March 31, 2017, March 31, 2016, or the year ended December 31, 2016. The changes in fair value related primarily to interest rate fluctuations. Our review of other-than-temporary impairment determined that there was no credit quality deterioration.
