Basis of Presentation

C.H. Robinson Worldwide, Inc. and our subsidiaries (“the company,” “we,” “us,” or “our”) are a global provider of transportation services and logistics solutions through a network of 234 branch offices operating in North America, Europe, Asia, South America, and Australia. The condensed consolidated financial statements include the accounts of C.H. Robinson Worldwide, Inc. and our majority owned and controlled subsidiaries. Our noncontrolling interests in subsidiaries are not significant. All intercompany transactions and balances have been eliminated in the condensed consolidated financial statements.

The condensed consolidated financial statements, which are unaudited, have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In our opinion, these financial statements include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the financial statements for the interim periods presented. Interim results are not necessarily indicative of results for a full year.

Consistent with SEC rules and regulations, we have condensed or omitted certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States. You should read the condensed consolidated financial statements and related notes in conjunction with the consolidated financial statements and notes in our Annual Report on Form 10-K for the year ended December 31, 2011.

Litigation

3. Litigation

We are not subject to any pending or threatened litigation other than routine litigation arising in the ordinary course of our business operations, including contingent auto liability cases. For such legal proceedings, we have accrued an amount that reflects the aggregate liability deemed probable and estimable, but this amount is not material to our consolidated financial position, results of operations, or cash flows. Because of the preliminary nature of many of these proceedings, the difficulty in ascertaining the applicable facts relating to many of these proceedings, the inconsistent treatment of claims made in many of these proceedings and the difficulty of predicting the settlement value of many of these proceedings, we are not able to estimate an amount or range of any reasonably possible additional losses. However, based upon our historical experience, the resolution of these proceedings is not expected to have a material effect on our financial condition, results of operations, or cash flows.

Fair Value Measurement
Fair Value Measurement

4. Fair Value Measurement

Accounting guidance on fair value measurements for certain financial assets and liabilities requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

 

   

Level 1—Quoted market prices in active markets for identical assets or liabilities.

 

   

Level 2—Observable market-based inputs or unobservable inputs that are corroborated by market data.

 

   

Level 3—Unobservable inputs reflecting the reporting entity’s own assumptions or external inputs from inactive markets.

A financial asset or liability’s classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement.

The following tables present information as of June 30, 2012 and December 31, 2011, about our financial assets and liabilities that are measured at fair value on a recurring basis, according to the valuation techniques we used to determine their fair values.

5. Stock Award Plans

Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense as it vests. A summary of our total compensation expense recognized in our statements of operations for stock-based compensation is as follows (in thousands):

Stock-based compensation expense

   $ 6,793       $ 10,099       $ 16,559       $ 22,609   

Our 1997 Omnibus Stock Plan allows us to grant certain stock awards, including stock options at fair market value and restricted shares and units, to our key employees, directors, and other third party service providers. A maximum of 28,000,000 shares can be granted under this plan; approximately 5,557,000 shares were available for stock awards as of June 30, 2012, which cover all equity compensation grants, including stock options and restricted stock awards. Awards that expire or are cancelled without delivery of shares generally become available for issuance under the plans.

Stock Options—We have awarded performance-based stock options to certain key employees. These options are subject to certain vesting requirements over a five-year period, based on the company’s earnings growth. Any options remaining unvested at the end of the five year vesting period are forfeited to the company. Although participants can exercise options via a stock swap exercise, we do not issue reloads (restoration options) on the grants from 2011.

The fair value of these options is established based on the market price on the date of grant, discounted for post-vesting holding restrictions, calculated using the Black-Scholes option pricing model. Changes in measured stock price volatility and interest rates are the primary reasons for changes in the discount. These grants are being expensed based on the terms of the awards. As of June 30, 2012, unrecognized compensation expense related to stock options was $13.5 million. The amount of future expense to be recognized will be based on the company’s earnings growth and certain other conditions.

Restricted Stock Awards—We have awarded performance-based restricted shares and restricted units to certain key employees and non-employee directors. These restricted shares and restricted units are subject to certain vesting requirements over a five-year period, based on the company’s earnings growth. The awards also contain restrictions on the awardees’ ability to sell or transfer vested shares or units for a specified period of time. The fair value of these shares is established based on the market price on the date of grant, discounted for post-vesting holding restrictions. For grants that are still available to vest, the discounts have varied from 18 percent to 22 percent and are calculated using the Black-Scholes option pricing model. Changes in the measured stock price volatility and interest rates are the primary reason for changes in the discount. These grants are being expensed based on the terms of the awards.

We have also awarded restricted shares and units to certain key employees that vest primarily based on their continued employment. The value of these awards is established by the market price on the date of the grant and is being expensed over the vesting period of the award.

We have also issued to certain key employees and non-employee directors restricted shares and units which are fully vested upon issuance. These shares and units contain restrictions on the awardees’ ability to sell or transfer vested shares and units for a specified period of time. The fair value of these shares is established using the same method discussed above. These grants have been expensed during the year they were earned.

As of June 30, 2012, there was unrecognized compensation expense of $148.8 million related to previously granted restricted shares and units. The amount of future expense to be recognized will be based primarily on the company’s earnings growth and certain other conditions.

 

Employee Stock Purchase Plan—Our 1997 Employee Stock Purchase Plan allows our employees to contribute up to $10,000 of their annual cash compensation to purchase company stock. Purchase price is determined using the closing price on the last day of the quarter, discounted by 15 percent. Shares are vested immediately. The following table summarizes employee stock purchase plan activity for the period:

C.H. Robinson Worldwide, Inc. and its 80 percent (or more) owned U.S. subsidiaries file a consolidated federal income tax return. We file unitary or separate state returns based on state filing requirements. With few exceptions, we are no longer subject to audits of U.S. federal, state and local, or non-U.S. income tax returns before 2007.
