The table below shows the amortized cost and fair value of the investment securities portfolio by contractual maturity. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties. Weighted average yield is based on amortized cost.

The unrecognized losses on held-to-maturity investment securities presented in the table above do not include unrecognized losses on securities that were transferred from available-for-sale to held-to-maturity totaling $137.9 million at June 30, 2023 and $148.9 million at December 31, 2022. These unrecognized losses are included as a separate component of shareholders’ equity and are being amortized over the remaining term of the securities.

No allowance for credit losses on available-for-sale debt securities was needed at June 30, 2023 or December 31, 2022.

An allowance on held-to-maturity debt securities is maintained for certain municipal bonds to account for expected lifetime credit losses. Substantially all of the U.S. government-sponsored entities and agencies and agency mortgage-backed securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies, and have a long history of no credit losses. Therefore, for those securities, we do not record expected credit losses. The allowance for credit losses on held-to-maturity debt securities was $0.2 million at June 30, 2023 and December 31, 2022.

Accrued interest receivable on the securities portfolio is excluded from the estimate of credit losses and totaled $50.6 million at June 30, 2023 and $50.9 million at December 31, 2022.

At June 30, 2023, Old National’s securities portfolio consisted of 3,047 securities, 2,808 of which were in an unrealized loss position. The unrealized losses attributable to our U.S. Treasury, U.S. government-sponsored entities and agencies, agency mortgage-backed securities, states and political subdivisions, and other securities are the result of fluctuations in interest rates and temporary market movements. Old National’s pooled trust preferred securities are evaluated using collateral-specific assumptions to estimate the expected future interest and principal cash flows. At June 30, 2023, we had no intent to sell any securities that were in an unrealized loss position nor is it expected that we would be required to sell the securities prior to their anticipated recovery.

Old National’s two pooled trust preferred securities with fair values totaling $11.0 million and unrealized losses totaling $2.8 million have experienced credit defaults. However, we believe that the value of the instruments lies in the full and timely interest payments that will be received through maturity, the steady amortization that will be experienced until maturity, and the full return of principal by the final maturity of the collateralized debt obligations. Old National did not recognize any losses on these securities for the six months ended June 30, 2023 or 2022.

Equity Securities

Equity securities consist of mutual funds for Community Reinvestment Act qualified investments and diversified investment securities held in a grantor trust for participants in the Company’s nonqualified deferred compensation plan. Old National’s equity securities with readily determinable fair values totaled $72.0 million at June 30, 2023 and $52.5 million at December 31, 2022. There were gains on equity securities of $0.1 million during the three

months ended June 30, 2023 and losses of $0.7 million during the six months ended June 30, 2023, compared to losses of $2.4 million and $4.2 million during the three and six months ended June 30, 2022, respectively.

Alternative Investments

Old National has alternative investments without readily determinable fair values that are included in other assets totaling $401.4 million at June 30, 2023, consisting of $243.1 million of illiquid investments in partnerships, limited liability companies, and other ownership interests that support affordable housing and $158.3 million of economic development and community revitalization initiatives in low-to-moderate income neighborhoods. These alternative investments totaled $396.8 million at December 31, 2022. There have been no impairments or adjustments on equity securities without readily determinable fair values, except for amortization of tax credit investments in the six months ended June 30, 2023 and 2022. See Note 9 to the consolidated financial statements for detail regarding these investments.
