We had a total of 208 debt securities with an unrealized loss position, of which 82 were in an unrealized loss position for less than one year and 126 were in an unrealized loss position for a period of one year or greater, as of June 30, 2023.  We held a total of 228 debt securities with an unrealized loss, of which 181 were in an unrealized loss position for less than one year and 47 were in an unrealized loss position for a period of one year or greater, as of December 31, 2022. We consider these unrealized losses as a temporary decline in value as they are on securities that we do not intend to sell and do not believe we will be required to sell prior to recovery of our amortized cost basis. The gross unrealized losses on the debt security positions at June 30, 2023 and December 31, 2022 were due predominately to market and interest rate fluctuations occurring in the ordinary course of business. Should we determine that a debt security in an unrealized loss position is likely to be sold before recovery of our amortized cost basis, we would recognize the unrealized loss.

Additionally, in accordance with ASU 2016-13, the Company estimates what is expected to not be collectable over the remaining life of its debt securities that are in an unrealized loss position by employing qualitative analysis without regard for time spent in an unrealized loss position. The significant inputs used to determine the amount of expected credit loss in our debt security portfolio begins with an analysis of held securities experiencing credit rating downgrades in the current reporting period.  Further inputs, such as performance indicators of the issuer’s business model, underlying assets, credit support and debt leverage are gathered as necessary based on our initial analysis step. If warranted, updated cash flow expectations are developed based on the aforementioned inputs. The Company concluded that based on current evidence there is no expected credit loss allowance necessary as of June 30, 2023. We presently expect that all debt securities held in our investment portfolio will be paid in accordance with their contractual terms.

Equity investments that are not consolidated or accounted for under the equity method of accounting with readily determinable fair values are not required to be evaluated for other-than-temporary-impairment.

The amortized cost and estimated fair value of debt securities at June 30, 2023 by contractual maturity are as follows. Expected maturities may differ from contractual maturities because certain borrowers may have the right to call or prepay obligations with or without penalties.
