Basis of Presentation

C.H. Robinson Worldwide, Inc. and our subsidiaries (“the company,” “we,” “us,” or “our”) are a global provider of multimodal freight services and logistics solutions. We operate through a network of 235 branch offices located in North America, Europe, Asia, South America, Australia, and the Middle East. 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 results of operations 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, 2010.

2. Goodwill and Intangible Assets

On September 26, 2011, we acquired certain assets of Timco Worldwide, a leading melon category provider in Davis, California. The results of Timco’s operations are not expected to be material to the consolidated financial statements. We recorded $2.4 million of goodwill and other intangible assets related to this acquisition.

Litigation

3. Litigation

On March 20, 2009, at the conclusion of a trial in Illinois State Court, Twelfth Judicial Circuit, Circuit Court of Will County, a jury entered a verdict of $23.75 million against us, a federally authorized motor carrier with which we contracted, and the motor carrier’s driver. The award was entered in favor of three named plaintiffs following a consolidated trial, stemming from an accident that occurred on April 1, 2004. The motor carrier and the driver both admitted that at the time of the accident the driver was acting as an agent for the motor carrier, and that the load was being transported according to the terms of our contract with the motor carrier. Our contract clearly defined the motor carrier as an independent contractor. The verdict has the effect of holding us vicariously liable for the damages caused by the admitted negligence of the motor carrier and its driver. There were no claims that our selection or retention of the motor carrier was negligent.

Given our prior experience with claims of this nature, we believe the court erred in allowing these claims to be considered by a jury. As a result, we sought relief from the verdict in the Appellate Court of Illinois, Third Judicial District. On March 30, 2011 the Illinois Court of Appeals issued an opinion affirming the verdict. We filed a petition for leave to appeal with the Illinois Supreme Court on April 13, 2011. We have been advised that the Illinois Supreme Court is unwilling to review the opinion issued by the Court of Appeals. In 2011, we recorded a charge of $6.2 million which represented our $5.0 million insurance deductible plus accrued post-judgment interest on that amount. Our insurance carrier is responsible for payment of the remaining verdict amount and related post-judgment interest. On October 14, 2011, the required payments were made to the plaintiffs and the judgments have been satisfied.

We are not subject to any other pending or threatened litigation other than routine litigation arising in the ordinary course of our business operations. 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 consolidated financial position, 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 September 30, 2011 and December 31, 2010, 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.

The estimated fair values of debt securities held as available-for-sale were based on other market data for comparable instruments and the transactions related in establishing the prices. In measuring the fair value of the contingent payment liability, we used an income approach that considers the expected future earnings of the acquired businesses and the resulting contingent payments, discounted at a risk-adjusted rate.

The table below sets forth a reconciliation of our beginning and ending Level 3 financial liability balance.

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

   $ 9,465       $ 10,187       $ 32,074       $ 22,568   

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 parties. A maximum of 28,000,000 shares can be granted under this plan; approximately 7,095,325 shares were available for stock awards as of September 30, 2011, which cover 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—The contractual lives of all options as originally granted are ten years. Options vested over a five-year period from the date of grant, with none vesting the first year and one quarter vesting each year after that. Recipients are able to exercise options using a stock swap which results in a new, fully-vested restoration option with a grant price established based on the date of the swap and a remaining contractual life equal to the remaining life of the original option. Options issued to non-employee directors vest immediately. The fair value per option is established using the Black-Scholes option pricing model, with the resulting expense being recorded over the vesting period of the award. Other than restoration options, we have not issued any new stock options since 2003. As of September 30, 2011, there was no unrecognized compensation expense related to stock options since all outstanding options were fully vested.

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. The discounts have varied from 12 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 September 30, 2011, there was unrecognized compensation expense of $137.2 million related to previously granted restricted equity. The amount of future expense will be based primarily on company performance, future awards, 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:
