Additionally, each non-employee director is entitled to receive an attendance fee of $1,400 for each meeting of the directors or any committee thereof, and to be reimbursed for reasonable fees and expenses incurred in connection with his or her service as a director. With the exception of the $52,000 non-employee Co-Chairman retainer, such retainers and fees paid to directors are provided, at the director’s election, 50% in cash compensation with the remaining 50% payable in our common shares, or 100% payable in our common shares. Non-employee directors are granted 12,500 restricted share units upon joining our board of directors and an additional 12,500 restricted share units after five years of service on our board of directors. The restricted share units vest over three years from the date of grant and are payable upon vesting in an equal number of our common shares.
