The Company provides an allowance for uncollectible accounts based on a review of outstanding receivables, historical collection information and existing economic conditions. The allowance for uncollectible amounts is continually reviewed and adjusted to maintain the allowance at a level considered adequate to cover potential future losses. This allowance is management's best estimate of uncollectible amounts and is determined based on historical collection experience related to accounts receivable coupled with a review of the current status of existing receivables. The losses ultimately incurred could differ materially in the near term from the amounts estimated in determining this allowance.

Any difference between the net book value of the property and equipment and the proceeds of an asset’s sale, or settlement of an insurance claim, is recorded as a gain or loss in the Company’s condensed consolidated statements of operations. Leases The Company conducts a major part of its operations from leased facilities. Each of these leases is accounted for as an operating lease.
