Sales of Available-for-Sale Debt Securities

Debt Securities by Contractual Maturity

The amortized cost and fair value of debt securities by contractual maturity at March 31, 2018 follow. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are detailed separately.

Corporate Bonds

The Bank’s floating rate corporate bonds were rated “investment grade” by accredited rating agencies as of their respective purchase dates. The total fair value of the Bank’s corporate bonds represented 10% and 9% of the Bank’s investment portfolio as of March 31, 2018 and December 31, 2017.

Mortgage Backed Securities and Collateralized Mortgage Obligations

At March 31, 2018, with the exception of the $4.1 million private label mortgage backed security, all other mortgage backed securities and collateralized mortgage obligations (“CMOs”) held by the Bank were issued by U.S. government-sponsored entities and agencies, primarily Freddie Mac and the Fannie Mae. At March 31, 2018 and December 31, 2017, there were gross unrealized losses of $3.2 million and $1.9 million related to available for sale mortgage backed securities and CMOs. Because these unrealized losses are attributable to changes in interest rates and illiquidity, and not credit quality, and because the Bank does not have the intent to sell these securities, and it is likely that it will not be required to sell the securities before their anticipated recovery, management does not consider these securities to have other-than-temporary impairment (“OTTI”).

Trust Preferred Security

During 2015, the Parent Company purchased a $3 million floating rate trust preferred security (“TRUP”) at a price of 68% of par. The coupon on this security is based on the 3-month London Interbank Borrowing Rate (“LIBOR”) rate plus 159 basis points. The Company performed an initial analysis prior to acquisition and performs ongoing analysis of the credit risk of the underlying borrower in relation to its TRUP.

At December 31, 2017, the Bank’s security portfolio consisted of 185 securities, 58 of which were in an unrealized loss position.

Other-than-temporary impairment

Unrealized losses for all debt securities are reviewed to determine whether the losses are “other-than-temporary.” Debt securities are evaluated for OTTI on at least a quarterly basis and more frequently when economic or market conditions warrant such an evaluation to determine whether a decline in value below amortized cost is other-than-temporary. In conducting this assessment, the Bank evaluates a number of factors including, but not limited to the following:

The length of time and the extent to which fair value has been less than the amortized cost basis;

The Bank’s intent to hold until maturity or sell the debt security prior to maturity;

An analysis of whether it is more-likely-than-not that the Bank will be required to sell the debt security before its anticipated recovery;

Adverse conditions specifically related to the security, an industry, or a geographic area;

The historical and implied volatility of the fair value of the security;

The payment structure of the security and the likelihood of the issuer being able to make payments;

Failure of the issuer to make scheduled interest or principal payments;

Any rating changes by a rating agency; and

Recoveries or additional decline in fair value subsequent to the balance sheet date.

The term “other-than-temporary” is not intended to indicate that the decline is permanent, but indicates that the prospects for a near-term recovery of value are not necessarily favorable, or that there is a general lack of evidence to support a realizable value equal to or greater than the carrying value of the investment. Once a decline in value is determined to be other-than-temporary, the value of the security is reduced and a corresponding charge to earnings is recognized for the anticipated credit losses.

The Bank owns one private label mortgage backed security with a total carrying value of $4.1 million at March 31, 2018. This security is mostly backed by “Alternative A” first lien mortgage loans, but also has an insurance “wrap” or guarantee as an added layer of protection to the security holder. This asset is illiquid, and as such, the Bank determined it to be a Level 3 security in accordance with Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures. Based on this determination, the Bank utilized an income valuation model (“present value model”) approach, in determining the fair value of the security. This approach is beneficial for positions that are not traded in active markets or are subject to transfer restrictions, and/or where valuations are adjusted to reflect illiquidity and/or non-transferability. Such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate is used. Management’s best estimate consists of both internal and external support for this investment.

See additional discussion regarding the Bank’s private label mortgage backed security under Footnote 9 “Fair Value” in this section of the filing.
