A limited perquisite program is also made available to Officers. Under the program, Officers may seek reimbursement for certain tax, estate and financial planning services up to a specified annual maximum each year, including the year following death or retirement. Officers are also offered an enhanced annual physical examination and the use of club memberships, with the majority of Officers limited to one membership. The Committee believes that these programs generally reflect prevailing market practices in the industry and are reasonable supplements to the overall compensation program.
On occasion spouses or other guests will accompany Officers on the aircraft for official business or when space is available on business-related flights. When the spouse or guests travel does not meet the IRS standard for business use, the cost of that travel is imputed as income to the Officer. If approved by his or her supervisor, the Officer may receive a gross up on the imputed income if the spouse or guest was accompanying the Officer on official business.
