Held-to-Maturity Securities

Idaho Power has a rabbi trust designated to provide funding for obligations related to the SMSP. During 2023 and 2022, the rabbi trust purchased $1.6 million and $31.2 million, respectively of held-to-maturity investments in corporate fixed-income and asset-backed debt securities. Substantially all of these debt securities mature between 2027 and 2037. Held-to-maturity investments are carried at amortized cost, reflecting Idaho Power’s ability and intent to hold the securities to maturity. Held-to-maturity investments are adjusted for the amortization or accretion of premiums or discounts, which are amortized or accreted over the life of the related held-to-maturity security. Such amortization and accretion are included in the “Other income, net” line in the consolidated statements of income. Due to increases in market interest rates in 2023 and 2022, all held-to-maturity securities were in a gross unrealized holding loss position totaling $3.3 million and $5.0 million at December 31, 2023 and December 31, 2022, respectively. Based on ongoing credit evaluations of these holdings, Idaho Power does not expect material payment defaults or delinquencies and has not recorded an allowance for credit losses for these securities as of December 31, 2023 and 2022.

IDACORP Financial Services Investments

IFS invests primarily in real estate tax credit projects, such as affordable housing developments, which provide a return principally by reducing federal and state income taxes through tax credits and accelerated tax depreciation benefits. IFS has focused on a diversified approach to its investment strategy in order to limit both geographic and operational risk, with most of IFS’s investments having been made through syndicated funds. IDACORP accounts for its equity-method investments in qualified real estate projects using the proportional amortization method and recognizes the net investment performance in the consolidated statements of income as a component of income tax expense.
