CASH AND CASH EQUIVALENTS. Cash and cash equivalents consist primarily of tax exempt and treasury money market funds with an original maturity of three months or less. The carrying amount approximates fair value due to the short maturity of the instruments.
PREPAID EXPENSES AND OTHER. Prepaid expenses and other include such items as prepaid rent, software maintenance contracts, insurance premiums, other prepaid operating expenses, and inventories, consisting primarily of produce and related products held for resale.
PROPERTY AND EQUIPMENT. Property and equipment are recorded at cost. Maintenance and repair expenditures are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated lives of the assets of 3 to 30 years. Amortization of leasehold improvements is computed over the shorter of the lease term or the estimated useful lives of the improvements.
We recognized depreciation expense of $20.7 million in 2008, $18.4 million in 2007, and $16.5 million in 2006. A summary of our property and equipment as of December 31 is as follows (in thousands):

INTANGIBLE ASSETS. Goodwill is the difference between the purchase price of a company and the fair market value of the acquired company’s net identifiable assets. Other intangible assets include customer lists, carrier lists, and non-competition agreements. These intangible assets are being amortized using the straight-line method over their estimated lives, ranging from three to five years. Goodwill is not amortized, but is tested for impairment using a fair value approach. Goodwill is tested for impairment annually or more frequently if events warrant. Intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. See Note 4.
OTHER ASSETS. Other assets include such items as purchased and internally developed software, and the investments related to our nonqualified deferred compensation plan. We recognized amortization expense of purchased and internally developed software of $4.3 million in 2008, $3.1 million in 2007, and $3.4 million in 2006. We amortize software using the straight-line method over three years.
