Stock-Based Compensation [Abstract]
Stock-Based Compensation	6. Stock-Based Compensation For the nine months ended September 30, 2021, we granted stock only stock appreciation rights (“SOSARs”) on 77 shares of our common stock to eligible employees. The weighted-average grant date fair value of the SOSARs was $397.44 per share with a weighted-average exercise price of $1,493.03 per share. The SOSARs vest in two equal installments on the second and third anniversary of the grant date. For the nine months ended September 30, 2021, 430 SOSARs were exercised, and 16 SOSARs were forfeited. For the nine months ended September 30, 2021, we granted restricted stock units (“RSUs”) on 24 shares of our common stock to eligible employees. The weighted-average grant date fair value of the RSUs was $1,479.78 per share. The RSUs generally vest in two equal installments on the second and third anniversary of the grant date. For the nine months ended September 30, 2021, 49 RSUs vested and 8 RSUs were forfeited.For the nine months ended September 30, 2021, we awarded performance share units (“PSUs”) on 18 shares of our common stock at target performance to eligible employees. These PSUs are subject to service, market and performance vesting conditions. The weighted-average grant date fair value of the PSUs was $1,479.55 per share, and the quantity of shares that will vest range from 0% to 300% of the targeted number of shares. If the defined minimum targets are not met, then no shares will vest. Further, in no event may more than 100% of the target number of PSUs vest if our 3 year total shareholder return is below the 25th percentile of the constituent companies comprising the S&P 500 on the day of grant. On December 30, 2020, due to the impact that the novel coronavirus (COVID-19) pandemic had on the growth in comparable restaurant sales and restaurant margin relative to the trajectory of both of these performance factors prior to the pandemic, and also due to the significant shareholder value created over the three-year performance period of the original award, the Compensation Committee of our Board of Directors modified the 2018 PSU award. This modification pertained to all seven recipients of this award, and resulted in an incremental compensation expense of $71,441, of which $55,463 was recognized during the nine months ended September 30, 2021, and $15,512 remains unamortized as of September 30, 2021. Based on the terms of the modification, 29 PSUs vested on March 15, 2021, pursuant to the original performance condition of the 2018 PSU award. To receive all incremental shares generated through the modification, the recipients of this award must remain employed through December 31, 2022, and the incremental shares will vest in four installments over this period. The first of the four installments vested on June 30, 2021, which included the vesting of 17 PSUs. The remaining expense will be recognized over this requisite service period. For the nine months ended September 30, 2021, no other PSUs vested, and 1 PSU was forfeited.
