Investments Debt And Equity Securities [Abstract]

Investments

2. INVESTMENTS

Our investments are primarily composed of fixed income debt securities and common stock equity securities. We carry our equity securities at fair value and categorize all of our debt securities as available-for-sale, which are carried at fair value.

Realized gains and losses on disposition of investments are based on the specific identification of the investments sold on the settlement date. The following is a summary of the disposition of fixed income and equity securities for the three-month periods ended March 31, 2025 and 2024:

Allowance for Credit Losses and Unrealized Losses on Fixed Income Securities

A reversable allowance for credit losses is recognized on available-for-sale fixed income securities, if applicable. Several criteria are reviewed to determine if securities in the fixed income portfolio should be included in the allowance for expected credit loss evaluation, including:

● Changes in technology that may impair the earnings potential of the investment,

● The discontinuance of a segment of business that may affect future earnings potential,

● Reduction of or non-payment of interest and/or principal,

● Specific concerns related to the issuer’s industry or geographic area of operation,

● Significant or recurring operating losses, poor cash flows and/or deteriorating liquidity ratios and

● Downgrades in credit quality by a major rating agency.

If changes in interest rates and credit spreads do not reasonably explain the unrealized loss for an available-for-sale security, or if any of the criteria above indicate a potential credit loss, the security is subjected to a discounted cash flow analysis. Inputs into the discounted cash flow analysis include prepayment assumptions for structured securities, default rates and recoverability rates based on credit rating. The allowance for any security is limited to the amount that the security’s fair value is below amortized cost. As of March 31, 2025, the discounted cash flow analysis resulted in an allowance for credit losses on 9 securities. The following table presents changes in the allowance for expected credit losses on available-for-sale securities:

	Three Months Ended March 31,
(in thousands)	2025		2024
Beginning balance	$	197	$	306
Increase to allowance from securities for which credit losses were not previously recorded		21		12
Reduction from securities sold during the period		—		(67)
Net increase (decrease) from securities that had an allowance at the beginning of the period		(61)		(14)
Balance as of March 31,	$	157	$	237

We recognized no losses on securities for which we no longer had the intent to hold until recovery during the first three months of 2025 and 2024.

As of March 31, 2025, in addition to the securities included in the allowance for credit losses, the fixed income portfolio contained 1,378 securities with an unrealized loss position for which an allowance for credit losses had not been recorded. The $190 million in associated unrealized losses represents 5 percent of the fixed income portfolio’s cost basis and 5 percent of total invested assets. Isolated to these securities, unrealized losses decreased through the first three months of 2025, as bonds rallied on falling interest rates. Of the total 1,378 securities, 982 have been in an unrealized loss position for 12 consecutive months or longer. The following table illustrates the total value of fixed income securities that were in an unrealized loss position as of March 31, 2025 and December 31, 2024 after factoring in the allowance for credit losses. All fixed income securities continue to pay the expected coupon payments and we believe we will recover the amortized cost basis of available-for-sale securities that remain in an unrealized loss position.

The following table shows the composition of the fixed income securities in unrealized loss positions, after factoring in the allowance for credit losses, at March 31, 2025 by the National Association of Insurance Commissioners (NAIC) rating and the generally equivalent Standard & Poor’s (S&P) and Moody’s ratings. The vast majority of the securities are rated by S&P and/or Moody’s.

Other Invested Assets

We had $60 million of other invested assets at March 31, 2025, compared to $58 million at December 31, 2024. Other invested assets include investments in low-income housing tax credit partnerships (LIHTC) and historic tax credit partnerships (HTC), membership in the Federal Home Loan Bank of Chicago (FHLBC), and investments in private funds. Our LIHTC and

HTC investments are carried at amortized cost and our investment in FHLBC stock is carried at cost. Due to the nature of the LIHTC, HTC and our membership in the FHLBC, their carrying amounts approximate fair value. The private funds are carried at fair value, using each investment’s net asset value.

Our LIHTC interests increased to $11 million at March 31, 2025, compared to $7 million at December 31, 2024, as additional investments were made. Our LIHTC interests recognized amortization of $1 million as a component of income tax expense and a total tax benefit of $1 million during the first quarter of 2025 and 2024. Our unfunded commitment for our LIHTC investments was $5 million at March 31, 2025 and will be paid out in installments through 2039.

Our HTC investment had a balance of $14 million at March 31, 2025, compared to $15 million at December 31, 2024. Our HTC investment recognized $1 million of amortization as a component of income tax expense and a total tax benefit of $1 million during the first quarter of 2025 and 2024. Our unfunded commitment for our HTC investments was $4 million at March 31, 2025 and will be paid out in installments through 2027.

At March 31, 2025, $56 million of investments were pledged as collateral with the FHLBC to ensure timely access to the secured lending facility that ownership of FHLBC stock provides. At March 31, 2025, $50 million of borrowings were outstanding with the FHLBC.

Our investments in private funds totaled $21 million at March 31, 2025, down from $24 million at December 31, 2024, and had $4 million of associated unfunded commitments at March 31, 2025. Our interest in private funds is generally restricted from being transferred or otherwise redeemed without prior consent by the respective entities, and the timed dissolution of the partnerships would trigger redemption.

Investments in Unconsolidated Investees

We had $57 million of investments in unconsolidated investees at March 31, 2025, compared to $56 million at December 31, 2024. At March 31, 2025, our investment in Prime Holdings Insurance Services, Inc. (Prime) was $56 million and other investments in unconsolidated investees totaled less than $1 million.

Cash and Short-Term Investments

Cash consists of uninvested balances in bank accounts. Short-term investments consist of investments with original maturities of 90 days or less, primarily AAA-rated government money market funds. Short-term investments are carried at cost. We had a cash and short-term investment balance of $27 million and $117 million, respectively, at March 31, 2025, compared to $40 million and $75 million, respectively, at December 31, 2024.
