|Share-Based Payment Arrangement [Abstract]
Stock-based compensation is awarded to employees and directors of the Company and accounted for in accordance with ASC 718, "Compensation—Stock Compensation". Stock-based compensation expense is recognized for equity awards over the vesting period based on their grant-date fair value. Stock-based compensation expense is included within the same financial statement caption where the recipient’s other compensation is reported. The Company accounts for forfeitures as they occur. The Company uses various forms of long-term incentives including, but not limited to restricted stock units ("RSUs") and performance-based restricted units ("PSUs"), provided that the granting of such equity awards is in accordance with the Company's 2021 Omnibus Incentive Plan (the "2021 Plan") as filed on Form S-8 with the SEC on December 27, 2021.
2021 Omnibus Incentive Plan
We adopted and obtained stockholder approval at the special meeting of the stockholders on October 19, 2021 of the 2021 Plan. We initially reserved 19,952,329 shares of our Class A common stock for issuance pursuant to awards under the 2021 Plan. The total number of shares of our Class A common stock available for issuance under the 2021 Plan will be increased on the first day of each fiscal year following the date on which the 2021 Plan was adopted in an amount equal to the least of (i) three percent (3%) of the outstanding shares of Class A common stock on the last day of the immediately preceding fiscal year, (ii) 9,976,164 shares of Class A common stock and (iii) such number of shares of Class A common stock as determined by the Committee (as defined and designated under the 2021 Plan) in its discretion. Pursuant to these automatic increase provisions, the number of shares of our Class A common stock reserved for issuance pursuant to awards under the 2021 Plan increased to 24,699,345 shares at January 1, 2022. Any employee, director or consultant of the Company or any of its subsidiaries or affiliates is eligible to receive an award under the 2021 Plan, to the extent that an offer of such award is permitted by applicable law, stock market or exchange rules, and regulations or accounting or tax rules and regulations. The 2021 Plan provides for the grant of stock options (including incentive stock options and non-qualified stock options), stock appreciation rights, restricted stock, RSUs, PSUs, other share-based awards, or any combination thereof. Each award will be set forth in a separate grant notice or agreement and will indicate the type and terms and conditions of the award.
The purpose of the 2021 Plan is to motivate and reward employees and other individuals to perform at their highest level and contribute significantly to the success of the Company. During the three months ended September 30, 2022, the Company granted 19,086 RSUs and no PSUs to certain members of the Company's Board of Directors and employees. The RSUs granted to employees are subject to service vesting conditions with one-third of each award vesting on the anniversary of the grant date such that all awards are fully vested after (3) years. The RSUs granted to a new non-employee director are subject to service vesting conditions with each award vesting in three equal quarterly installments on December 15, 2022, March 15, 2023, and June 15, 2023. The expense will be recognized on a straight-line basis over the related service period for each tranche of awards.
During the three and nine months ended September 30, 2022, $1.6 million and $4.3 million, respectively, of stock-based compensation expense was recorded, of which $0.1 million and $0.5 million, respectively was related to non-employee directors.
In addition, during the three and nine months ended September 30, 2022, certain members of the Company's Directors elected to receive their quarterly retainer fees in the form of shares of Class A common stock. As such, the Company recorded related stock-based compensation expense for $0.1 million and $0.3 million, respectively, in the same periods.
In conjunction with entering into the Business Combination Agreement, on June 17, 2021 the Sponsor issued 4,200,000 Profits Interests to Lawrence Kingsley, the current Chairman of the Board of Directors of the Company, 3,200,000 Profits Interests to Thomas Logan, the Chief Executive Officer of Mirion, and 700,000 Profits Interests to Brian Schopfer, the Chief Financial Officer of Mirion. The Profits Interests are intended to be treated as profits interests for U.S. income tax purposes, pursuant to which Messrs. Logan, Schopfer and Kingsley will have an indirect interest in the founder shares held by the Sponsor.
The Profits Interests are subject to service vesting conditions and market vesting conditions. Fifty percent (50%) of the Profits Interests granted to each of Messrs. Logan and Schopfer service-vest on each of the second and third anniversaries of the Closing, and fifty percent (50%) of the Profits Interests granted to Mr. Kingsley service-vest on each of the first and second anniversaries of the Closing), subject in each case to the continuous service of the grantee on such date. The market vesting conditions require that the price per share of Mirion's Class A common stock must meet or exceed certain established thresholds for 20 out of 30 trading days before the fifth anniversary of the Closing Date). The expense will be recognized on a straight-line basis over the related service period for each tranche of awards.
Of the Profits Interests, 3.2 million have a market vesting threshold price of $12 per share of Mirion Class A common stock, 2.0 million have a threshold price of $14 per share of Mirion Class A common stock, and 3.0 million have a threshold price of $16 per share of Mirion Class A common stock.
During the three and nine months ended September 30, 2022, $6.8 million and $20.3 million, respectively, of stock-based compensation expense was recorded and no new Profit Interests were issued.
