Level 2: Inputs that are observable in the marketplace other than those inputs classified as Level 1. Level 3: Inputs that are unobservable in the marketplace and significant to the valuation. *Derivative Financial Instruments* As a result of the Company’s international operations, it is exposed to various market risks that may affect its consolidated results of operations, cash flows and financial position. These market risks include, but are not limited to, fluctuations in currency exchange rates. The Company’s primary foreign currency exposures are in Euros and British Pound Sterling. The Company faces exposure to adverse movements in currency exchange rates as the financial results of its operations are translated from local currency into U.S. dollars upon consolidation. Additionally, foreign exchange rate fluctuations on transactions denominated in currencies other than the functional currency result in gains and losses that are reflected in income. The Company may enter into derivative instruments to hedge certain net exposures of nonfunctional currency denominated assets and liabilities, even though it does not elect to apply hedge accounting or hedge accounting does not apply. Gains and losses resulting from a change in fair value for these derivatives are reflected in income in the period in which the change occurs and are recognized on the consolidated statement of operations in other income (expense). Cash flows from these contracts are classified within net cash provided by (used in) operating activities on the consolidated statements of cash flows. The Company does not use financial instruments for trading or speculative purposes. The Company recognizes all derivative instruments on the balance sheet at fair value and its derivative instruments are generally short-term in duration. The derivative contracts were not material as of October 31, 2012. The Company is exposed to the risk that counterparties to derivative contracts may fail to meet their contractual obligations. There have been no other significant changes or updates to the Company’s significant accounting policies disclosed in its Form 10-K. *Recently Adopted Accounting Pronouncements* *Goodwill* In September 2011, the FASB issued ASU 2011-08, “Intangibles – Goodwill and Other: Testing Goodwill for Impairment,” which simplifies the periodic testing of goodwill for impairment. This guidance will allow companies to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test required under current accounting standards. This guidance will be effective for the Company’s annual goodwill impairment test performed in 2013 and is not expected to have a material impact on the Company’s consolidated financial statements. *Comprehensive Income* In June 2011, the FASB issued a standard 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. The standard eliminates the option to present the components of other comprehensive income as part of the statement of equity. The updated accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 on a retrospective basis. Early application is permitted.

The Company’s significant accounting policies and recent accounting pronouncements are described in Note 2 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended April 30, 2012, filed on June 11, 2012. The unaudited condensed consolidated financial statements and notes included herein should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Form 10-K.

Unaudited Interim Financial Information

The accompanying unaudited condensed consolidated financial statements and notes have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“U.S. GAAP”), as contained in the Financial Accounting Standards Board (“FASB”), Accounting Standards Codification for interim financial information and Article 10 of Regulation S-X issued by the United States Securities and Exchange Commission (“SEC”). Accordingly, they do not include all the information and footnotes required by U.S. GAAP for annual fiscal reporting periods. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, changes in stockholders’ equity and cash flows. The results of operations for the three and six months ended October 31, 2012 are not necessarily indicative of results that may be expected for the year ending April 30, 2013 or any other period.

Fair Value of Financial Instruments

The Company applies the authoritative guidance on fair value measurements for financial assets and liabilities and non-financial assets and liabilities, such as goodwill, indefinite-lived intangible assets and property plant and equipment that are measured at fair value on a non-recurring basis. The guidance defines fair value, thereby eliminating inconsistencies in guidance found in various prior accounting pronouncements, and increases disclosures surrounding fair value calculations. The guidance establishes a three-tiered fair value hierarchy that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of inputs are defined as follows:

Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets accessible by the Company.

Level 2: Inputs that are observable in the marketplace other than those inputs classified as Level 1.

Level 3: Inputs that are unobservable in the marketplace and significant to the valuation.

Derivative Financial Instruments

As a result of the Company’s international operations, it is exposed to various market risks that may affect its consolidated results of operations, cash flows and financial position. These market risks include, but are not limited to, fluctuations in currency exchange rates. The Company’s primary foreign currency exposures are in Euros and British Pound Sterling. The Company faces exposure to adverse movements in currency exchange rates as the financial results of its operations are translated from local currency into U.S. dollars upon consolidation. Additionally, foreign exchange rate fluctuations on transactions denominated in currencies other than the functional currency result in gains and losses that are reflected in income.

The Company may enter into derivative instruments to hedge certain net exposures of nonfunctional currency denominated assets and liabilities, even though it does not elect to apply hedge accounting or hedge accounting does not apply. Gains and losses resulting from a change in fair value for these derivatives are reflected in income in the period in which the change occurs and are recognized on the consolidated statement of operations in other income (expense). Cash flows from these contracts are classified within net cash provided by (used in) operating activities on the consolidated statements of cash flows.

The Company does not use financial instruments for trading or speculative purposes. The Company recognizes all derivative instruments on the balance sheet at fair value and its derivative instruments are generally short-term in duration. The derivative contracts were not material as of October 31, 2012. The Company is exposed to the risk that counterparties to derivative contracts may fail to meet their contractual obligations.

There have been no other significant changes or updates to the Company’s significant accounting policies disclosed in its Form 10-K.

Recently Adopted Accounting Pronouncements

Goodwill

In September 2011, the FASB issued ASU 2011-08, “Intangibles – Goodwill and Other: Testing Goodwill for Impairment,” which simplifies the periodic testing of goodwill for impairment. This guidance will allow companies to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test required under current accounting standards. This guidance will be effective for the Company’s annual goodwill impairment test performed in 2013 and is not expected to have a material impact on the Company’s consolidated financial statements.

Comprehensive Income

In June 2011, the FASB issued a standard 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. The standard eliminates the option to present the components of other comprehensive income as part of the statement of equity. The updated accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 on a retrospective basis. Early application is permitted. The Company adopted the updated guidance in the first quarter of the fiscal year ending April 30, 2013.
