Recently Issued Accounting Pronouncements</b></font></p> <p style="FONT-FAMILY: times;"><font size="2">        In July 2013, the Financial Accounting Standards Board ("FASB") issued authoritative guidance that requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. This guidance is effective for the Company in the first quarter of fiscal 2015. The Company does not anticipate that the adoption of this guidance will have a material impact on its consolidated financial statements.</font></p> <p style="FONT-FAMILY: times;"><font size="2">        In March 2013, FASB issued authoritative guidance that resolves the diversity in practice regarding the release into net income of the cumulative translation adjustment upon derecognition of a subsidiary or group of assets within a foreign entity. This guidance will be effective for the Company beginning in the first quarter of fiscal 2015. The Company does not anticipate that the adoption of this guidance will have a material impact on its consolidated financial statements, absent any material transactions involving the derecognition of subsidiaries or groups of assets within a foreign entity.</font></p> <p style="FONT-FAMILY: times;"><font size="2">        In December 2011, the FASB issued authoritative guidance that requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. In January 2013, the FASB issued authoritative guidance to clarify the scope of the guidance issued in December 2011. Specifically, the scope is specified to apply only to derivatives, repurchase agreements and reverse purchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with specific criteria contained in the authoritative guidance or subject to a master netting arrangement or similar agreement. This guidance will be effective for the Company beginning in the first quarter of fiscal 2014. The Company does not anticipate that the adoption of this guidance will have a material impact on its financial statement disclosures, absent any material transactions that fall within the scope of this authoritative guidance.</font></p> </div>

The Company bases estimates on historical experience and on various assumptions about the future believed to be reasonable based on available information. The Company's reported financial position or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. If estimates or assumptions differ from actual results, subsequent periods are adjusted to reflect more current information.</font></p> </div>

In the normal course of business, the Company's financial position is routinely subject to market risks associated with foreign currency rate fluctuations due to balance sheet positions in foreign currencies. The Company evaluates foreign exchange risks and utilizes foreign currency forward contracts to reduce such risks, hedging the gains or losses generated by the remeasurement of significant foreign currency denominated monetary assets and liabilities. The fair value of these contracts is reflected as other assets or other liabilities and the change in fair value of these foreign currency forward contracts is recorded as income or loss in the Company's Consolidated Statements of Operations as a component of Interest and other income (expense), net to largely offset the change in fair value of the foreign currency denominated monetary assets and liabilities which is also recorded as a component of interest and other income (expense), net.</font></p> </div>
