Fair Value Measurements
Fair Value Measurements	3. Fair Value Measurements Fair value is defined as the price that the Company would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. The three-tier hierarchy of inputs is summarized in the three broad levels listed below: Level 1—Unadjusted quoted prices are available in active markets for identical investments as of the reporting date. Level 2—Pricing inputs are quoted prices for similar investments in active markets; quoted prices for identical or similar investments in inactive markets; or valuations based on models where the significant inputs are observable or can be corroborated by observable market data. Level 3—Pricing inputs into models are unobservable for the investment. The unobservable inputs require significant management judgment or estimation. To measure fair value, the Company obtains quoted market prices for its investment securities from its outside investment managers. If a quoted market price is not available, the Company uses prices of similar securities. The fair values obtained from the outside investment managers are reviewed for reasonableness and any discrepancies are investigated for final valuation. The fair value of the Company’s investments in fixed maturity securities is estimated using relevant inputs, including available market information, benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. An Option Adjusted Spread model is also used to develop prepayment and interest rate scenarios. Industry standard models are used to analyze and value securities with embedded options or prepayment sensitivities. These fair value measurements are estimated based on observable, objectively verifiable market information rather than market quotes. Therefore, these investments are classified and disclosed in Level 2 of the hierarchy.

Reserve for Losses and Loss Adjustment Expenses The following table represents a reconciliation of changes in the ending reserve balances for losses and loss adjustment expenses (“LAE”): ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, ​ 2023 2022 ​ ​ (in thousands) Reserve for losses and LAE net of reinsurance recoverables at beginning of period ​ $ 77,520 ​ $ 45,419 Add: Incurred losses and LAE, net of reinsurance, related to: ​ ​ ​ ​ ​ ​ Current year ​ 17,300 ​ ​ 13,449 Prior years ​ 3,352 ​ ​ 1,505 Total incurred ​ 20,652 ​ 14,954 Deduct: Loss and LAE payments, net of reinsurance, related to: ​ ​ Current year ​ ​ 1,393 ​ ​ 1,490 Prior years ​ ​ 15,413 ​ ​ 7,497 Total payments ​ 16,806 ​ 8,987 Reserve for losses and LAE net of reinsurance recoverables at end of period ​ 81,366 ​ 51,386 Add: Reinsurance recoverables on unpaid losses and LAE at end of period ​ ​ 183,601 ​ ​ 113,726 Reserve for losses and LAE gross of reinsurance recoverables on unpaid losses and LAE at end of period ​ $ 264,967 ​ $ 165,112 ​ Considerable variability is inherent in the estimate of the reserve for losses and LAE. Although management believes the liability recorded for losses and LAE is adequate, the variability inherent in this estimate could result in changes to the ultimate liability, which may be material to stockholders’ equity. ​ The Company experienced adverse prior year development of $3.4 and $1.5 million during the three months ended March 31, 2023 and 2022, respectively. ​ Adverse prior year development during the three months ended March 31, 2023 was primarily due to higher than anticipated severity of attritional losses, offset by lower than anticipated severity of catastrophe losses. Adverse prior year development during the three months ended March 31, 2022 was primarily due to higher than anticipated severity of attritional losses from prior years.

For performance stock units (“PSUs”), any changes to expense resulting from differences in actual performance versus target are recognized over the remaining vesting period of the awards. The Company does not apply a forfeiture rate to unvested awards and accounts for forfeitures as they occur. All stock-based compensation is included in other underwriting expenses in the Company’s unaudited condensed consolidated statement of income and comprehensive income. 2019 Equity Incentive Plan On April 16, 2019, the Company's 2019 Equity Incentive Plan (the “2019 Plan”) became effective. The 2019 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance shares and units, and other cash-based or share-based awards. In addition, the 2019 Plan contains a mechanism through which the Company may adopt a deferred compensation arrangement in the future. A total of 2,400,000 shares of common stock were initially authorized and reserved for issuance under the 2019 Plan. This reserve increases on January 1 of each year through 2029 by an amount equal to the smaller of: 3% of the number of shares of common stock issued and outstanding on the immediately preceding December 31, or an amount determined by the board of directors. Stock Options Recipients of stock options can purchase shares of the Company’s common stock at a price equal to the stock's fair market value on the grant date, determined by the closing price of the Company's common stock on the grant date. Stock options vest over a two vesting first grant period The following table summarizes stock option transactions for the three months ended March 31, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Number of shares ​ ​ Weighted-average exercise price ​ Weighted-average remaining contractual term (in years) ​ ​ Aggregate intrinsic value (in thousands) Outstanding at January 1, 2023 882,892 ​ $ 33.85 ​ - ​ $ - Options granted - ​ ​ - ​ ​ ​ ​ ​ Options exercised (5,957) ​ ​ 15.24 ​ ​ ​ ​ ​ Options canceled (3,589) ​ ​ 64.91 ​ ​ ​ ​ ​ Outstanding at March 31, 2023 873,346 ​ $ 33.85 ​ 6.63 ​ $ 23,374 Vested and Exercisable at March 31, 2023 724,939 ​ $ 28.15 ​ 6.33 ​ $ 22,598 ​ As of March 31, 2023, the Company had approximately $2.9 ​ ​ ​ ​ Restricted Stock Units RSUs are valued using the closing price of the Company’s common stock on their grant date.

Performance Stock Units The Company issues PSUs with a combination of service, performance, and market conditions. The majority of PSUs were issued via grants made to certain executives during 2021. These PSUs are earned based on the achievement of stock price milestones. If the Company’s stock price reaches and remains at certain milestones for 30 days, the PSUs shall become earned units and will vest upon completion of a requisite service period of approximately five years from the date of grant. As of March 31, 2023, none of the stock price milestones have been achieved. For other PSUs outstanding, vesting of PSUs requires a period of future service and the number of shares that vest depends on performance relative to predetermined targets of the Company’s Gross Written Premiums and Adjusted Return on Equity as set by the Compensation Committee. Prior to 2023, the PSU’s performance period was the fiscal year of the grant. Beginning in 2023, the PSU’s performance period is primarily a three-year period beginning with the grant date. At the end of the performance period, the actual results are measured against the predetermined targets to determine the number of PSUs to be earned as compensation. The earned PSUs are then subject to a required service period of approximately three years from the grant date before vesting and being issued as common stock. The following table summarizes PSU transactions for the three months ended March 31, 2023: ​ ​ ​ ​ ​ ​ ​ Number of shares ​ ​ Weighted-average grant date fair value Outstanding at January 1, 2023 383,103 ​ $ 37.62 Granted 44,354 ​ ​ 51.25 Vested — ​ ​ — Forfeited (1,098) ​ ​ 55.36 Non-vested outstanding at March 31, 2023 426,359 ​ $ 38.99 ​ The PSU grants above represent the number of shares that would vest based on achievement of all stock price milestones in the 2021 executive stock grants and the 100% achievement of the predetermined performance conditions for the other PSU grants. The actual number of PSUs which will vest is subject to adjustment based on the Company’s actual stock price performance and financial performance relative to the predetermined targets. As of March 31, 2023, the Company had approximately $12.5 2019 Employee Stock Purchase Plan On April 16, 2019, the Company's 2019 Employee Stock Purchase Plan “the “2019 ESPP”) became effective. A total of 240,000 shares of common stock are initially authorized and reserved for issuance under the 2019 ESPP. In addition, the 2019 ESPP provides for annual increases in the number of shares available for issuance on January 1 of each year through 2029, equal to the smaller of 240,000 shares of the Company’s common stock or such other amount as may be determined by the board of directors. Under the 2019 ESPP, employees can purchase Company stock at a discount via payroll withholdings. The 2019 ESPP is administered through employee participation in discrete offering periods. During each discrete offering period employee funds are withheld, and the stock purchase occurs upon the conclusion of the offering period. The Company issued 7,724 shares pursuant to the ESPP during the three months ended March 31, 2023. Share repurchases In January 2022, the Board of Directors approved a new share repurchase program which replaced the existing program and authorized the repurchase of up to $100 million of outstanding shares of common stock over the period ending on March 31, 2024. The Company purchased 134,680 shares for $6.8 million during the three months ended March 31, 2023. The Company accounts for share repurchases by charging the excess of repurchase price over the common stock’s par value entirely to retained earnings. All repurchased shares are retired and become authorized but unissued shares.
