Express Scripts 2009 Annual Report 64
We have restricted cash and cash equivalents in the amount of $9.1 million and $4.8 million at December
31, 2009 and 2008, respectively. These amounts consist of investments and cash which include participants’ health
savings accounts, employers’ pre-funding amounts and Express Scripts Insurance Company (“ESIC”) restricted for
state insurance licensure purposes.
Accounts receivable. Based on our revenue recognition policies discussed below, certain claims at the end
of a period are unbilled. Revenue and unbilled receivables for those claims are estimated each period based on the
amount to be paid to network pharmacies and historical gross margin. Estimates are adjusted to actual at the time of
billing. Historically, adjustments to our original estimates have been immaterial. As of December 31, 2009 and
2008, unbilled receivables for continuing operations were $1,218.4 million and $561.9 million, respectively.
Unbilled receivables are billed to clients typically within 30 days based on the contractual billing schedule agreed
upon with the client.
We provide an allowance for doubtful accounts equal to estimated uncollectible receivables. This estimate
is based on the current status of each customer’s receivable balance as well as current economic and market
conditions. Receivables are written off against the allowance only upon determination such amounts are not
recoverable and all collection attempts have failed. As of December 31, 2009 and 2008, we have an allowance for
doubtful accounts for continuing operations of $93.5 million and $76.8 million, respectively.
Inventories. Inventories consist of prescription drugs and medical supplies which are stated at the lower
of first-in first-out cost or market.
Property and equipment. Property and equipment is carried at cost and is depreciated using the straight-
line method over estimated useful lives of seven years for furniture and three to five years for equipment and
purchased computer software. Buildings are amortized on a straight-line basis over estimated useful lives of ten
years to thirty-five years. Leasehold improvements are amortized on a straight-line basis over the remaining term of
the lease or the useful life of the asset, if shorter. Expenditures for repairs, maintenance and renewals are charged to
income as incurred. Expenditures that improve an asset or extend its estimated useful life are capitalized. When
properties are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the
accounts and any gain or loss is included in income.
Research and development expenditures relating to the development of software for internal purposes are
charged to expense until technological feasibility is established. Thereafter, the remaining software production costs
up to the date placed into production are capitalized and included as property and equipment. We capitalized $24.0
million of internally developed software during 2009. Amortization of the capitalized amounts commences on the
date placed into production, and is computed on a product-by-product basis using the straight-line method over the
remaining estimated economic life of the product but not more than five years. Reductions, if any, in the carrying
value of capitalized software costs to net realizable value are expensed. With respect to capitalized software costs,
we recorded amortization expense of $21.9 million in 2009, $21.3 million in 2008 and $18.2 million in 2007.
Marketable securities. All investments not included as cash and cash equivalents are accounted for in
accordance with applicable accounting guidance for investments in debt and equity securities. Management
determines the appropriate classification of our marketable securities at the time of purchase and re-evaluates such
determination at each balance sheet date. All marketable securities at December 31, 2009 and 2008 were recorded
in other non-current assets on our consolidated balance sheet (see Note 2).
Securities bought and held principally for the purpose of selling them in the near term are classified as
trading securities. Trading securities are reported at fair value, which is based upon quoted market prices, with
unrealized holding gains and losses included in earnings. We held trading securities, consisting primarily of mutual
funds, totaling $11.4 million and $12.8 million at December 31, 2009 and 2008, respectively. We maintain our
trading securities to offset changes in certain liabilities related to our deferred compensation plan discussed in Note
12. Net gain (loss) recognized on the trading portfolio was $3.8 million, ($5.2) million, and $1.9 million in 2009,
2008, and 2007, respectively.
Securities not classified as trading or held-to-maturity securities are classified as available-for-sale
securities. Available-for-sale securities are reported at fair value, which is based upon quoted market prices, with
unrealized holding gains and losses reported through other comprehensive income, net of applicable taxes. We sold
shares held as available-for-sale for a non-operating gain of $4.2 million in the second quarter of 2007.
