Substantially concurrent with the IPO, the Company's Board of Directors adopted the Ryan Specialty Group Holdings, Inc. 2021 Omnibus Incentive Plan (the “Omnibus Plan”). The Omnibus Plan provides for potential grants of the following awards: (i) stock options, (ii) stock appreciation rights, (iii) restricted stock awards; (iv) performance awards, (v) other stock-based awards, (vi) other cash-based awards, and (vii) analogous equity awards made in equity of RSG LLC.

As a result of the Organizational Transactions, pre-IPO holders of RSG LLC Class A common units that were granted as incentive awards, which had historically been classified as equity and vested pro rata over five years, were required to exchange their units for one or more of the following: (i) Restricted Stock, (ii) Reload Options, (iii) Restricted Common Units, or (iv) Reload Class C Incentive Units, collectively, the Replacement Awards. The reload awards were issued to employees in order to protect against the dilution of their existing awards upon exchange to the new awards.

Separately, certain employees were granted one or more of the following new awards: (i) Restricted Stock Units, (ii) Staking Options, (iii) Restricted LLC Units, or (iv) Staking Class C Incentive Units.

The Restricted Stock and Restricted Common Units are referred to as “restricted” for either (i) the lock-up period (“Lock-up Period” as defined by the Omnibus Plan) as it relates to the Company's restriction on any granted awards being sold or transferred for the six month period following the effective date of our IPO Prospectus, or (ii) the transfer restriction on all Restricted Stock and Restricted Common Units awarded to employees that are subject to transfer restrictions, on a non-linear schedule, for the five year period following the IPO. As these restrictions lift based on the passage of time, Restricted Stock and Restricted Common Units will be referred to as Class A common stock and LLC Common Units, respectively. All awards granted as part of the Organizational Transactions and the IPO are subject to the aforementioned Lock-up Period and transfer restrictions.

Equity-based Awards Modification

As noted above, as a result of the Organizational Transactions and the IPO, pre-IPO holders of RSG LLC Class A common units exchanged their units for the Replacement Awards. This exchange was considered a modification as of the IPO date as a result of the change in terms and conditions of the existing awards and the issuance of new options and profits interests that have different vesting schedules than the exchanged awards. This modification resulted in the re-measurement of the awards in accordance with ASC 718. Total compensation cost recognized for the modified awards equaled the grant date fair value from the pre-IPO grants, plus any incremental compensation cost measured at the modification date (i.e. the IPO date). The modification impacted approximately 380 employees.

The incremental compensation expense arising from the modification is primarily driven by the right to future TRA payments as a result of the Organizational Transactions, as well as the TRA Alternative Payments, offset by the existence of new transfer restrictions that extend beyond vesting dates. The TRA, as detailed in Note 2, Summary of Select Significant Accounting Policies, provides for the potential, future payment to certain LLC Unitholders of tax benefits realized by the Company. The right to these potential future payments is considered in the calculation of the fair value of the Restricted Common Units and Reload Class C Incentive Units granted to employees. Additionally, those employees who exchanged their granted units into Restricted Stock received a one-time lump sum TRA Alternative Payment in an aggregate amount of $37.6 million. These one-time cash payments were paid upon the closing of the IPO on July 26, 2021. The cash payments were treated as a cash settlement of a portion of the existing awards, and therefore, included in the post-IPO value for determining the incremental expense in the modification. The remaining unamortized fair value as of the modification date will be recognized as equity-based compensation allocated on a relative fair value basis of the awards over the remaining service periods.

Restricted Stock

As part of the Organizational Transactions, certain existing employee unitholders were granted Restricted Stock in the Company in exchange for their LLC Units, which were first exchanged into LLC Common Units. The Restricted Stock follows the vesting schedule of the LLC Units for which they were exchanged. LLC Units historically vested pro rata over 5 years. Restricted Stock activity for the period was as follows:

The weighted-average grant date fair value of $21.15 reflects the fair value of the Restricted Stock at the time of the modification. 10,076,870 shares of Restricted Stock were granted at the time of the IPO, 5,554,873 of which were fully vested. The fully vested cash settlement of the TRA Alternative Payments included in the post modification value, as detailed above, resulted in a significant portion of the grant date fair value being recognized in the current quarter.

Restricted Stock Units (RSUs)

Related to the IPO, the Company granted RSUs to certain employees. RSUs vest either pro rata over 5 years from the grant date or over 10 years from the grant date, with 10% vesting in each of years 3 through 9 and 30% vesting in year 10. The grant date fair value considers the IPO price of $23.50 adjusted for a weighted average 2.4% discount for lack of marketability due to the transfer restrictions. Upon vesting, RSUs automatically convert on a one-for-one basis into Class A common stock.

Stock Options

Reload Options

As part of the Organizational Transactions and IPO, certain employees who exchanged their LLC Common Units for shares of the Company were also granted Reload Options that entitle the award holder to future purchases of Class A common stock, on a one-for-one basis, at the IPO price of $23.50. The Reload Options vest either 100% 3 years from the grant date or over 5 years from the grant date, with 33.3% vesting in each of years 3, 4 and 5. Vested Reload Options are exercisable up to the tenth anniversary of the grant date.

Staking Options

In addition to Restricted Stock, certain employees were also granted Staking Options that entitle the award holder to future purchases of Class A common stock, on a one-for-one basis, at the IPO price of $23.50. The Staking Options vest over 10 years from the grant date, with 10% vesting in each of years 3 through 9 and 30% vesting in year 10. Vested Staking Options are exercisable up to the eleventh anniversary of the grant date.

The use of a valuation model for the Reload Options and Staking Options requires management to make certain assumptions with respect to selected model inputs. Expected volatility was calculated based on the observed volatility for comparable companies. The expected time to maturity was based on the weighted-average vesting terms and contractual terms of the awards. The dividend yield was based on the Company’s expected dividend rate. The risk-free interest rate was based on U.S. Treasury rates commensurate with the expected life of the award.

All Stock Options outstanding were issued at the time of the IPO. No additional options have been issued to date. The aggregate intrinsic value and weighted average remaining contractual terms of Stock Options outstanding and Stock Options exercisable were as follows as of September 30, 2021:

Restricted Common Units

As part of the Organizational Transactions, certain existing employee unitholders were granted Restricted Common Units in exchange for their LLC Units. The Restricted Common Units follow the vesting schedule of the LLC Units for which they were exchanged. LLC Units historically vested pro rata over 5 years. Restricted Common Unit activity for the period was as follows:

The weighted average grant date fair value reflects the fair value of the Restricted Common Units at the time of the modification. 27,493,192 Restricted Common Units were granted at the time of the IPO, 20,861,266 of which were fully vested. The potential TRA payment value included in the post modification value associated with vested awards, as detailed above, resulted in a significant portion of the grant date fair value being recognized in the current quarter.

Restricted LLC Units (RLUs)

Related to the IPO, the Company granted RLUs to certain employees that vest either pro rata over 5 years from the grant date or over 10 years from the grant date, with 10% vesting in each of years 3 through 9 and 30% vesting in year 10. Upon vesting, RLUs automatically convert on a one-for-one basis into LLC Common Units.

Class C Incentive Units

Reload Class C Incentive Units

As part of the Organizational Transactions and IPO, certain employees who exchanged their LLC Units for Restricted Common Units were also granted Reload Class C Incentive Units, which are profits interests. When the value of Class A common stock exceeds the IPO price of $23.50, any vested profits interests may be exchanged for LLC Common Units of equal value. On exchange, the LLC Common Units may immediately be redeemed on a one-to-one basis for Class A common stock. The Reload Class C Incentive Units vest either 100% 3 years from the grant date or over 5 years from the grant date, with 33.3% vesting in each of years 3, 4 and 5.

Staking Class C Incentive Units

Related to the IPO, certain employees were granted Staking Class C Incentive Units, which are profits interests. When the value of the Class A common stock exceeds the IPO price of $23.50, any vested profits interests may be exchanged for LLC Common Units of equal value. On exchange, the LLC Common Units may immediately be redeemed on a one-to-one basis for Class A common stock. The Staking Class C Incentive Units vest either pro rata over 5 years from the grant date or over 10 years from the grant date, with 10% vesting in each of years 3 through 9 and 30% vesting in year 10.

The Restricted Common Units and RLUs, once vested and after delivery of LLC Common Units, are exchangeable into shares of Class A common stock of the Company on a one-to-one basis, which entitles the unitholders to TRA payments resulting from 85% of the tax savings generated by the Company as described in Note 2, Summary of Select Significant Accounting Policies. The Reload Class C Incentive Units and Staking Class C Incentive Units have the same terms as the LLC Common Units, with the exception of

the participation threshold of $23.50. When the price of the Class A common stock exceeds the participation threshold, the Class C Incentive Units can be exchanged for Restricted Common Units of equal value and are entitled to the same TRA payments upon an exchange to Class A common stock. In order to value the Restricted Common Units, RLUs, and Class C Incentive Units we are required to make certain assumptions with respect to selected model inputs.

Due to the nature of the underlying risks inherent in TRA payments and the uncertainty as to when the participation threshold will be satisfied for the Class C Incentive Units, we use a Monte Carlo simulation to explicitly model the impact of future stock prices on the size of the amortizable asset, as well as the impact of different levels of taxable income on the timing of the TRA payments, in a risk-neutral framework. The Monte Carlo simulation model uses the following assumptions: the simulated closing stock price, the simulated taxable income, the risk-free interest rate, the expected dividend yield, and the expected volatility and correlation of the Company's stock price and taxable income. The dividend yield was based on the Company’s expected dividend rate of 0.0%. The risk-free interest rate of 1.9% was based on U.S. Treasury rates commensurate with a term of 30 years. Due to the transfer restrictions, a discount for lack of marketability was applied based on the term between when each Restricted Common Unit, RLU or Class C Incentive Unit vests, and when it is released from the transfer restriction. The range of discounts from 6.0% to 19.1% were applied on the proportion of value associated with the receipt of Class A common stock upon the exchange of each Restricted Common Unit, RLU, or Class C Incentive Unit.

Equity-based Compensation Expense

The following table includes the equity-based compensation expense the Company realized in the three months ended September 30, 2021 by expense type from the view of expense related to pre- and post-IPO awards. The table also presents the unrecognized equity-based compensation expense as of September 30, 2021 in the same view. A similar view has not been presented for the nine months ended September 30, 2021 as all equity based-compensation expense related to legacy RSG LLC equity would be included in the first line of the table.
