The Company elected to exclude accrued interest receivable (“AIR”) from the amortized cost basis of debt securities disclosed throughout this footnote.  For available-for-sale (“AFS”) debt securities, AIR totaled $8.7 million and $8.4 million as of March 31, 2022, and December 31, 2021, respectively.  For held-to-maturity (“HTM”) debt securities, AIR totaled $7.8 million and $8.2 million as of March 31, 2022, and December 31, 2021, respectively.  AIR is included in the “accrued interest receivable” line item on the Company’s consolidated statements of condition.

The table below presents an analysis of the contractual maturities of the Company’s investment securities as of March 31, 2022.  Debt securities issued by government agencies (Small Business Administration securities) and mortgage-backed securities are disclosed separately in the table below as these investment securities may prepay prior to their scheduled contractual maturity dates.

Investment securities with carrying values of $3.1 billion and $2.9 billion as of March 31, 2022, and December 31, 2021, respectively, were pledged to secure deposits of governmental entities, securities sold under agreements to repurchase, and FRB discount window borrowing.

The Company does not believe that the AFS debt securities that were in an unrealized loss position as of March 31, 2022, which were comprised of 422 individual securities, represent a credit loss impairment.  As of March 31, 2022, and December 31, 2021, the gross unrealized loss positions were primarily related to mortgage-backed securities issued by U.S. government agencies or U.S. government-sponsored enterprises.  These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss.  Total gross unrealized losses were primarily attributable to changes in interest rates, 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 were in an unrealized loss position 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.

Substantially all of the Company’s HTM debt securities are issued by U.S. government agencies or U.S. government-sponsored enterprises.  These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss.  Therefore, an allowance for credit losses for these securities was not deemed necessary as of March 31, 2022.  

 

 

Interest income from taxable and non-taxable investment securities for the three months ended March 31, 2022, and March 31, 2021, were as follows:

These securities can only be redeemed or sold at their par value and only to the respective issuing institution or to another member institution.  The Company records these non-marketable equity securities as a component of other assets and periodically evaluates these securities for impairment.  Management considers these non-marketable equity securities to be long-term investments.  Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value.
