Management fees are recognized at the time the related services have been performed, unless future contingencies exist. In addition, in regard to management and facility service contracts, the owner of the property will typically reimburse the Company for certain expenses that are incurred on behalf of the owner, which are comprised primarily of on-site employee salaries and related benefit costs. The amounts which are to be reimbursed per the terms of the services contract are recognized as revenue in the same period as the related expenses are incurred. In certain instances, the Company subcontracts property management services to independent property managers, in which case the Company passes a portion of their property management fee on to the subcontractor, and the Company retains the balance. Accordingly, the Company records these fees net of the amounts paid to subcontractors.</p> </div>
