Acquisitions and Significant Accounting Policies
Goodwill	Goodwill During the first nine months of 2014, we recorded goodwill of $100.4 million in our land segment and goodwill of $26.6 million in our aviation segment in connection with the 2014 acquisitions and we increased land segment goodwill by $0.4 million as a result of a reduction in identifiable intangible assets based on our ongoing fair value assessment of certain of our 2013 acquisitions. Additionally, we had goodwill decreases of $0.7 million, $0.3 million and $0.1 million as a result of foreign currency translation adjustments of our non-U.S. dollar functional currency subsidiaries in our land, marine and aviation segments, respectively.
Other Investments	Other Investments As of September 30, 2014 and December 31, 2013, we had other investments, consisting primarily of equity investments, net of basis adjustments, of $106.4 million and $83.8 million, respectively, which are included within identifiable intangible and other non-current assets in the accompanying consolidated balance sheets.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Presentation of Financial Statements-Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. In August 2014, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) which requires management of the Company to evaluate whether there is substantial doubt about the Company’s ability to continue as a going concern. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, with early adoption permitted. We do not expect the adoption of this new guidance to have an impact on our financial statement disclosures. Compensation-Stock Compensation. In June 2014, the FASB issued an ASU which includes guidance which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures. Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. In June 2014, the FASB issued an ASU which changes the accounting for repurchase-to-maturity transactions and repurchase financing arrangements. It also requires additional disclosures about repurchase agreements and other similar transactions. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures. Revenue from Contracts with Customers. In May 2014, the FASB issued an ASU which provides guidance for revenue recognition for any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. We are currently evaluating whether the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures. Presentation of Financial Statements and Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. In April 2014, the FASB issued an ASU which changes the criteria for reporting discontinued operations while enhancing disclosures in this area. It also addresses sources of confusion and inconsistent application related to financial reporting of discontinued operations guidance. This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures. Presentation of an Unrecognized Tax Benefit When a Net Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. In July 2013, the FASB issued an ASU on the presentation of an unrecognized tax benefit when a net operating loss carryforward exists. Under this guidance, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward. This update became effective at the beginning of our 2014 fiscal year. The adoption of this ASU did not have a significant impact on our consolidated financial statements and disclosures. Foreign Currency Matters Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Foreign Subsidiaries. In March 2013, the FASB issued an ASU aimed at resolving the diversity in practice of accounting for the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. In addition, the amendments in this ASU resolve the diversity in practice for the treatment of business combinations achieved in stages (sometimes also referred to as step acquisitions) involving a foreign entity. This update became effective at the beginning of our 2014 fiscal year. The adoption of this ASU did not have a significant impact on our consolidated financial statements and disclosures. Disclosure Obligations Resulting from Joint and Several Liability Arrangements. In February 2013, the FASB issued an ASU clarifying the guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this ASU is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. This update became effective at the beginning of our 2014 fiscal year. The adoption of this ASU did not have a significant impact on our consolidated financial statements and disclosures.
Reclassifications	Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period’s presentation.

Disclosure of accounting policy for the equity method of accounting for investments in common stock or other interests including unconsolidated subsidiaries, corporate joint ventures, noncontrolling interests in real estate ventures, limited partnerships, and limited liability companies. The accounting policy may include information such as: (1) initially recording an investment in the stock of an investee at cost; (2) adjusting the carrying amount of the investment to recognize the investor's share of the earnings or losses of the investee after the date of acquisition; and (3) adjustments to reflect the investor's share of changes in the investee's capital (dividends). This disclosure may also include a detailed description of the policy for determining the amount of equity method losses recognized after an investment has been reduced to zero as a result of previous losses, reasons for not using the equity method when the investor company owns 20 percent or more of the voting stock of the investee's company (including identification of the significant investee), reasons for using the equity method when the ownership percentage is less than 20 percent, and discussion of recognition of equity method losses when an investor's total investment in an investee includes, in addition to an investment in common stock, other investments such as preferred stock and loans to the investee. An entity also may describe how such investments are assessed for impairment.
