CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our consolidated financial statements include accounts of the company and all majority-owned subsidiaries. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions. In certain circumstances, those estimates and assumptions can affect amounts reported in the accompanying consolidated financial statements and related footnotes. In preparing our financial statements, we have made our best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materiality. We do not believe there is a great likelihood that materially different amounts would be reported related to the accounting policies described below. However, application of these accounting policies involves the exercise of judgment and use of assumptions as to future uncertainties and, as a result, actual results could differ from these estimates. Note 1 of the Notes to Consolidated Financial Statements includes a summary of the significant accounting policies and methods used in the preparation of our consolidated financial statements. The following is a brief discussion of our critical accounting policies and estimates.

Revenue recognition. Gross revenues consist of the total dollar value of goods and services purchased from us by customers. Gross profits are gross revenues less the direct costs of transportation, products, and handling. We act principally as the service provider for these transactions and recognize revenue as these services are rendered or goods are delivered. At that time, our obligations to the transactions are completed and collection of receivables is reasonably assured. Emerging Issues Task Force (EITF) Issue No. 99-19, Reporting Revenue Gross as a Principal versus Net as an Agent, establishes the criteria for recognizing revenues on a gross or net basis. Most transactions in our Transportation and Sourcing businesses are recorded at the gross amount we charge our customers for the service we provide and goods we sell. In these transactions, we are the primary obligor, we are a principal to the transaction, we have all credit risk, we maintain substantially all risks and rewards, we have discretion to select the supplier, and we have latitude in pricing decisions.

Additionally, in our Sourcing business, we take loss of inventory risk during shipment and have general inventory risk. Certain transactions in customs brokerage, transportation management, and all transactions in Information Services are recorded at the net amount we charge our customers for the service we provide because many of the factors stated above are not present.

Valuations for accounts receivable. Our allowance for doubtful accounts is calculated based upon the aging of our receivables, our historical experience of uncollectible accounts, and any specific customer collection issues that we have identified. The allowance of $29.3 million as of December 31, 2008, increased compared to the allowance of $28.0 million as of December 31, 2007. We believe that the recorded allowance is sufficient and appropriate based on our customer aging trends, the exposures we have identified, and our historical loss experience.

Goodwill. We manage and report our operations as one operating segment. Our branches represent a series of components that are aggregated for the purpose of evaluating goodwill for impairment on an enterprise-wide basis. In the case where we have an acquisition that we feel has not yet become integrated into our branch network component, we will evaluate the impairment of any goodwill related to that specific acquisition and its results. Based on our annual analysis in accordance with SFAS No. 142, we have determined that there is no indication of goodwill impairment as of December 31, 2008.

Stock-based compensation. We account for share-based compensation in accordance with SFAS No. 123R, Share Based Payment. Under this standard, the fair value of each share-based payment award is established on the date of grant. For grants of restricted shares and restricted units, the fair value is established based on the market price on the date of the grant, discounted for post-vesting holding restrictions. The discounts have varied from 12 to 22 percent and are calculated using the Black-Scholes option pricing model. Increased stock price volatility is the primary factor that has caused the change in the discount applied. For grants of options, we use the Black-Scholes option pricing model to estimate the fair value of share-based payment awards. The determination of the fair value of share-based awards is affected by our stock price and a number of assumptions, including expected volatility, expected life, risk-free interest rate, and expected dividends.
