Share-based Payment Arrangement [Abstract] |
Share-based compensation | Share-based compensation 2011 Equity Incentive Plan In March 2011, the Company adopted its Equity Incentive Plan, or 2011 Plan, to attract and retain the most highly qualified and capable professionals and to promote the success of its business. This Plan is being used to reward certain employees for the success of the Company’s business through an annual award program. The 2011 Plan permits grants of awards relating to class A shares, including awards in the form of shares (also referred to as stock), options, restricted shares, restricted share units, share appreciation rights, performance awards and other share-based awards as will be determined by the Company’s Board of Directors. The maximum number of shares that may be issued under the 2011 Plan is 2.5% of the Company’s total outstanding class A and class B shares immediately following its initial public offering 2011. The Company made a special grant of stock options and restricted share units in 2011 in connection with its initial public offering, which are totally vested. The Company also made recurring grants of stock options and restricted share units in each of the fiscal years from 2011 to 2019 (from 2015 to 2019 only restricted share units). From 2011 to 2018, both types of these recurring annual awards vest as follows: 40% on the second anniversary of the date of grant and 20% on each of the following three anniversaries. The 2019 award vested on May 10, 2020. However, in the event of death, disability or retirement of the employee, any unvested portion of the annual award will be fully vested. For all grants, each stock option granted represents the right to acquire a Class A share at its grant-date fair market value, while each restricted share unit represents the right to receive a Class A share when vested. The exercise right for the stock options is cumulative and, once such right becomes exercisable, it may be exercised in whole or in part during quarterly window periods until the date of termination, which occurs at the seventh anniversary of the grant date. The Company utilizes a Black-Scholes option-pricing model to estimate the value of stock options at the grant date. The value of restricted shares units is based on the quoted market price of the Company’s class A shares at the grant date. 2011 Equity Incentive Plan (continued) On June 28, 2016, 1,117,380 stock options were converted to a liability award maintaining the original conditions of the 2011 Plan. There were not incremental compensation costs resulting from the modification. The employees affected by this modification were 104. The accrued liability was remeasured on a monthly basis until settlement. This liability award plan expired on May 2020. The Company recognizes stock-based compensation expense on a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award was, in substance, multiple awards. The Company recognized stock-based compensation expense related to this award in the amount of $1,564, $1,884 and $3,661 during fiscal years 2020, 2019 and 2018, respectively. Stock-based compensation expense is included within “General and administrative expenses” in the consolidated statements of income. The Company recognized $(244), $(422) and $(175) of related income tax expense during fiscal years 2020, 2019 and 2018, respectively.

Phantom RSU Award In May 2019, the Company implemented a new long-term incentive plan (called Phantom RSU Award) to reward employees giving them the opportunity to share the success of the Company in the creation of value for its shareholders. In accordance with this plan, the Company granted units (called “Phantom RSU”) to certain employees, pursuant to which they are entitled to receive, when vested, a cash payment equal to the closing price of one Class A share on the respective day in which this benefit is due and the corresponding dividends per-share (if any) formally declared and paid during the service period. The award has two types of grant. Phantom RSU type one has 465,202 units which vest over a requisite service period of five years as follows: 40% at the second anniversary of the date of grant and 20% at each of the following three years. Phantom RSU type two has 1,207,455 units which vest 100% at the fifth anniversary from the date of grant. However, in the event of death, disability or retirement of the employee, any unvested portion of the annual award will be fully vested. The Company recognizes compensation expense related to these benefits on a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award was, in substance, multiple awards. The grant-date stock price of both types of grants was $6.78. On December 2020, the Company implemented a new Phantom RSU type two with 65,440 units at a price of $4.89 that vest 100% at May 2021.
