Our equity-based compensation plans provide for the granting of Options and RSUs to key management employees, including executive officers and members of our Board of Directors ("Directors"). The exercise price of Options granted is equal to the closing price of our common stock on the New York Stock Exchange (the “NYSE”) on the day prior to the date of grant. Options are granted for a 10-year term and typically vest in separate tranches over periods of 3 to 6 years. RSUs generally vest in separate tranches over periods of 2 to 6 years. Grants are generally divided such that vesting for 50% of the grant is contingent solely on continued employment or service as a Director, while vesting for the remaining 50% of the grant is contingent upon both continued employment or service as a Director and the achievement of a performance metric based on our return on capital performance relative to a peer group during a 3-year period specified on the date of grant.

To estimate the grant-date fair value of our Options, we use the Black-Scholes option-pricing model (the “Pricing Model”). The Pricing Model estimates the per share fair value of an option on its date of grant based on the following factors: the option’s exercise price; the price of the underlying stock on the date of grant; the estimated dividend yield; a risk-free interest rate; the estimated option term; and the expected volatility. For the risk-free interest rate, we use U.S. Treasury STRIPS which mature at approximately the same time as the option’s expected holding term. For expected volatility, we have concluded that our historical volatility over the option’s expected holding term provides the most reasonable basis for this estimate.

Compensation cost for Options and RSUs is recognized on a straight-line basis over the requisite service period for the entire award (from the date of grant through the period of the last separately vesting portion of the grant). For the recognition of equity-based compensation, the Options and RSUs which are subject to a performance condition are treated as a separate award from the “service-only” Options and RSUs, and compensation cost is recognized when it becomes probable that the stated performance target will be achieved. We currently believe that it is probable that the stated performance condition will be satisfied at the target level for all of our Options and RSUs granted. Compensation cost is recognized within the income statement in the same expense line as the cash compensation paid to the respective employees.

We recognize forfeitures of equity-based awards as a reduction to compensation costs in the period in which they occur. In 2020, 2019 and 2018, we recognized $50,794, $78,532, and $75,701 in equity-based compensation costs, respectively, and approximately $10,500, $16,800, and $17,200 in tax benefit related to equity-based compensation costs, respectively.

As of December 31, 2020, the total unrecognized compensation cost for all outstanding Options and RSUs equaled approximately $169,500. The unrecognized compensation cost will be recognized over each grant’s applicable vesting period with the latest vesting date being December 31, 2027. The weighted-average period over which the unrecognized compensation cost will be recorded is equal to approximately 2.2 years.

We settle Option exercises and vesting of RSUs by issuing shares of treasury stock. Shares are relieved from the treasury account based on the weighted average cost of treasury shares acquired. During the years ended December 31, 2020, 2019 and 2018, we issued 159, 276 and 188 shares, respectively, from the treasury account for Option exercises and vesting of RSUs. Information with respect to the vested RSUs and exercised Options is as follows:

We have a trustee-administered, profit sharing retirement plan (the “Profit Sharing Plan”) and an Employee Stock Ownership Plan (“ESOP”) covering substantially all employees. The Profit Sharing Plan and the ESOP provide for annual discretionary contributions in amounts as determined by our Directors. The combined plan contribution for the years ended December 31, 2020, 2019 and 2018 was approximately $22,500, $20,300 and $19,500, respectively. We purchased approximately 5 shares of our common stock in the open market for each of the 2020 and 2019 plan year contributions to the ESOP. As of December 31, 2020, all shares held by the ESOP had been allocated to participants’ accounts. The 2020 plan year contribution was funded and fully allocated to participants in February 2021.

We have two deferred compensation plans (“Deferred Comp Plans”). The specific purpose of the Deferred Comp Plans is to i) establish a vehicle whereby named executive officers may defer the receipt of salary and bonus that otherwise would be nondeductible for Company tax purposes into a period where we would realize a tax deduction for the amounts paid, and ii) to enable certain employees who are subject to our stock holding requirements to acquire shares of our common stock on a pre-tax basis in order to more quickly meet, and maintain compliance with those stock holding requirements. Amounts deferred into the Deferred Comp Plans are invested in our common stock, held in a rabbi trust account, and are paid out in a fixed number of shares upon expiration of the deferral period.
