In management’s opinion, all adjustments comprising normal recurring adjustments necessary for a fair presentation of such condensed consolidated financial statements have been made. The accompanying condensed consolidated financial statements and notes in this Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2012 ("Quarterly Report") are presented as permitted by Regulation S-X and do not contain certain information included in our annual financial statements and notes thereto. Accordingly, the accompanying condensed consolidated financial information should be read in conjunction with the consolidated financial statements presented in our Annual Report on Form 10-K for the year ended December 31, 2011 ("2011 Annual Report"). European Sovereign Debt Crisis – At March 31, 2012, we had no direct investments in European sovereign or non-sovereign debt. However, certain of our defined benefit plans hold investments in European equity and fixed income securities as discussed in Note 12 of our 2011 Annual Report. Other than broad, macro-level economic impacts, we did not experience any direct or measurable disruptions during the three months ended March 31, 2012 due to the European sovereign debt crisis. We will continue to monitor and evaluate the impact of any future developments in the region on our current business, our customers and suppliers and the state of the global economy. Events in North Africa and Middle East – As previously disclosed in our 2011 Annual Report, during 2011 political and economic conditions in North Africa caused us to experience shipment delays to this region. For the three months ended March 31, 2012 there was no impact to operating income due to delayed shipments to this region. The preponderance of our physical assets in the region are located in the Kingdom of Saudi Arabia and the United Arab Emirates and have, to date, not been significantly affected by the unrest elsewhere in the region. Accounting Policies Significant accounting policies, for which no significant changes have occurred in the three months ended March 31, 2012, are detailed in Note 1 to our consolidated financial statements included in our 2011 Annual Report. Accounting Developments Pronouncements Implemented In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2011-04, "Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs," which clarifies the requirements in accounting principles generally accepted in the United States ("U.S. GAAP") for measuring fair value and for disclosing information about fair value measurements in order to improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. GAAP and International Financial Reporting Standards ("IFRSs"). The amendments do not result in a major change in the application of the requirements in Topic 820 but clarify the application of existing fair value measurement requirements and change particular principles or requirements for measuring fair value and for disclosing information about fair value measurements. Our adoption of ASU No. 2011-04, effective January 1, 2012, had no impact on our consolidated financial condition and results of operations. In June 2011, the FASB issued ASU No. 2011-05, "Comprehensive Income (Accounting Standards Codification ("ASC") 220): Presentation of Comprehensive Income," which specifies that an entity has the option to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This amendment also requires an entity to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income. In December 2011, the FASB issued ASU No. 2011-12, "Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05," to defer the requirement to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income. Our adoption of ASU Nos. 2011-05 and 2011-12, effective January 1, 2012, had no impact on our consolidated financial condition and results of operations. In September 2011, the FASB issued ASU No. 2011-08, "Intangibles - Goodwill and Other (ASC 350): Testing Goodwill for Impairment," which specifies that an entity has the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. An entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying amount. Our adoption of ASU No. 2011-08, effective January 1, 2012, had no impact on our consolidated financial condition and results of operations. Pronouncements Not Yet Implemented In December 2011, the FASB issued ASU No. 2011-11, "Disclosures about Offsetting Assets and Liabilities," which requires enhanced disclosures about financial instruments and derivative instruments that are either (1) offset in accordance with either ASC 210-20-45, "Balance Sheet - Offsetting," or ASC 815-10-45, "Derivatives and Hedging - Overall," or (2) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in accordance with either ASC 210-20-45 or ASC 815-10-45. ASU No. 2011-11 is effective for fiscal years, and interim periods within those years, beginning after December 31, 2012. The disclosure requirements shall be applied retrospectively for all periods presented. The adoption of ASU No. 2011-11 will not have an impact on our consolidated financial condition and results of operations.
