Basis of Presentation

Note 1: Basis of Presentation

We have prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements and these unaudited financial statements should be read in conjunction with the audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended November 30, 2010.

We have made no significant changes in the application of our significant accounting policies that were disclosed in our Annual Report on Form 10-K for the fiscal year ended November 30, 2010.

We have prepared the accompanying unaudited condensed consolidated financial statements on the same basis as the audited financial statements included in our Annual Report on Form 10-K, and these financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results of the interim periods presented. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full fiscal year.

Common Stock Split

On December 20, 2010, our Board of Directors approved a three-for-two common stock split in the form of a stock dividend. Shareholders received one additional share for every two shares held. The distribution was made on January 28, 2011 to shareholders of record at the close of business on January 12, 2011. All share and per share amounts in this Quarterly Report on Form 10-Q have been adjusted to reflect the stock split.

Recent Accounting Pronouncements

Presentation of Comprehensive Income

In June 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220)—Presentation of Comprehensive Income (ASU 2011-05), to require an entity 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. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. ASU 2011-05 is effective for us in our first quarter of fiscal 2013 and should be applied retrospectively. We are currently evaluating the impact of our pending adoption of ASU 2011-05 on our consolidated financial statements.

Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements

In May 2011, the FASB issued Accounting Standards Update No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (Topic 820)—Fair Value Measurement (ASU 2011-04), to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for level 3 fair value measurements. ASU 2011-04 is effective for us in our second quarter of fiscal 2012 and should be applied prospectively. We are currently evaluating the impact of our pending adoption of ASU 2011-04 on our consolidated financial statements.

Disclosure of Supplementary Pro Forma Information for Business Combinations: In December 2010, the FASB issued Accounting Standards Update No. 2010-29, Disclosure of Supplementary Pro Forma Information for Business Combinations (Topic 805)—Business Combinations (ASU 2010-29), to improve consistency in how the pro forma disclosures are calculated. Additionally, ASU 2010-29 enhances the disclosure requirements and requires description of the nature and amount of any material, nonrecurring pro forma adjustments directly attributable to a business combination. ASU 2010-29 is effective for us in fiscal 2012 and should be applied prospectively to business combinations for which the acquisition date is after the effective date. Early adoption is permitted. We will adopt ASU 2010-29 in fiscal 2012 and do not believe it will have a material impact on our consolidated financial statements.

Performing Step 2 of the Goodwill Impairment Test

In December 2010, the FASB issued Accounting Standards Update No. 2010-28, When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts (Topic 350)—Intangibles—Goodwill and Other (ASU 2010-28). ASU 2010-28 amends the criteria for performing Step 2 of the goodwill impairment test for reporting units with zero or negative carrying amounts and requires performing Step 2 if qualitative factors indicate that it is more likely than not that a goodwill impairment exists. We will adopt ASU 2010-28 in fiscal 2012 and any impairment to be recorded upon adoption will be recognized as an adjustment to our beginning retained earnings. We are currently evaluating the impact of the pending adoption of ASU 2010-28 on our consolidated financial statements.

Disclosure Requirements Related to Fair Value Measurements

In January 2010, the FASB issued Accounting Standards Update No. 2010-06, Improving Disclosures about Fair Value Measurements (Topic 820)—Fair Value Measurements and Disclosures (ASU 2010-06), to add additional disclosures about the different classes of assets and liabilities measured at fair value, the valuation techniques and inputs used, and the activity in Level 3 fair value measurements (as defined in Note 7 below). Certain provisions of this update will be effective for us in fiscal 2012 and we are currently evaluating the impact of the pending adoption of ASU 2010-06 on our consolidated financial statements.
