New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS Standards Implemented In May 2011, the Financial Accounting Standards Board (the “FASB”) issued updated accounting guidance to amend existing requirements for fair value measurements and disclosures. The guidance expands the disclosure requirements around fair value measurements categorized in Level 3 of the fair value hierarchy and requires disclosure of the level in the fair value hierarchy of items that are not measured at fair value but whose fair value must be disclosed. It also clarifies and expands upon existing requirements for fair value measurements of financial assets and liabilities as well as instruments classified in shareholders’ equity. The guidance was effective for the Company for the interim period ended April 30, 2012. The adoption of this guidance did not materially impact the Company's condensed consolidated financial statements. In June 2011, the FASB issued accounting guidance, which revises the manner in which entities present comprehensive income in their financial statements. The new guidance eliminates the option to present components of other comprehensive income as part of the statement of equity. Under the new guidance, entities are required to present net income and other comprehensive income in either a single continuous statement or in two separate, but consecutive, statements of net income and other comprehensive income. The amended and updated guidance was effective for the Company for the interim period ended April 30, 2012 and has been applied retrospectively as required by this standard. Other than the change in presentation, adoption of this guidance did not impact the Company's condensed consolidated financial statements. Standards to be Implemented In July 2012, the FASB issued new accounting guidance on indefinite-lived intangible assets. The new guidance provides an entity the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount and recognize an impairment loss, if any, to the extent the carrying value exceeds its fair value. The guidance is effective for the Company for annual and, if any, interim impairment tests performed in the fiscal years beginning after September 15, 2012, with early adoption permitted. The Company believes that the adoption of this guidance will not have a material impact on the Company's condensed consolidated financial statements.
