Recently Issued Accounting Pronouncements</font><font style="font-family:Times New Roman;font-size:10pt;font-style:normal;font-weight:bold;text-decoration:none;"> </font></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In May 2017, the Financial Accounting Standards Board (“FASB”) issued guidance that clarifies the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under the relevant authoritative guidance. The guidance is to be applied prospectively, and is effective for the Company in the first quarter of fiscal 2019. Early adoption is permitted. The Company does not anticipate the adoption of this guidance to have a material impact on its consolidated financial statements, absent any award(s) modified on or after adoption date.</font></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In November 2016, the FASB issued guidance that will require that the amounts generally described as restricted cash and restricted cash equivalents would be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period amounts shown on the statement of cash flows. The new guidance also requires certain disclosures to supplement the statement of cash flows. The guidance is effective for the Company in the first quarter of fiscal 2019. Other than changes in the presentation within the statements of cash flows and additional required disclosures, the adoption of this new accounting guidance will not have an impact on the consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In October 2016, the FASB issued guidance that requires entities to recognize at the transaction date the income tax consequences of intra-entity transfer of an asset other than inventory. The guidance is effective for the Company in the first quarter of fiscal 2019. The Company is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In June 2016, the FASB issued guidance that changes the accounting for recognizing impairments of financial assets. Under the new guidance, credit losses for certain types of financial instruments will be estimated based on expected losses. The new guidance also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. The guidance is effective for the Company in the first quarter of fiscal 2021 and earlier adoption is permitted. The Company is evaluating the impact of adopting this new accounting guidance on its consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In March 2016, the FASB issued guidance which simplifies several aspects of accounting for share-based payment award transactions including income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The guidance is effective for the Company in the first quarter of fiscal 2018. The most significant impact from this guidance upon adoption for the Company relates to the classification of employee tax paid by withholding shares of restricted stock units on the statements of cash flows and excess tax benefit. Upon adoption, the related cash flows will be classified as financing activity, from the current classification as operating activity and all prior periods presented will be retrospectively adjusted to reflect this change. The employee tax paid by withholding shares totaled </font><font style="font-family:inherit;font-size:10pt;">$14.3 million</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">$11.4 million</font><font style="font-family:inherit;font-size:10pt;"> in fiscal </font><font style="font-family:inherit;font-size:10pt;">2017</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">2016</font><font style="font-family:inherit;font-size:10pt;">, respectively. In addition, the guidance requires that the excess tax benefits to be recorded on the income statement as opposed to additional paid-in-capital. Due to the Company’s valuation allowance on its deferred tax assets, </font><font style="font-family:inherit;font-size:10pt;">no</font><font style="font-family:inherit;font-size:10pt;"> income tax benefit is expected to be recognized upon adoption. All other aspects of the guidance are not expected to have a material effect on the Company’s consolidated financial statements. </font></div><div style="line-height:120%;padding-bottom:0px;padding-top:0px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In February 2016, the FASB issued guidance regarding both operating and financing leases, requiring lessees to recognize on their balance sheets “right-of-use assets” and corresponding lease liabilities, measured on a discounted basis over the lease term. Virtually all leases will be subject to this treatment except leases that meet the definition of a “short-term lease.” The guidance requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The guidance is effective for the Company in the first quarter of fiscal 2020. While the Company is not yet in a position to assess the full impact of the application of the new guidance, the Company expects adoption of this guidance will materially increase the assets and liabilities recorded on its Consolidated Balance Sheets.</font></div><div style="line-height:120%;padding-bottom:0px;padding-top:0px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;padding-bottom:0px;padding-top:0px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In May 2014, the FASB issued new authoritative guidance related to revenue recognition from contracts with customers. This new guidance will replace current U.S. GAAP guidance on this topic and eliminate industry-specific guidance. The new guidance provides a unified model to determine when and how revenue is recognized. The core principle of the new guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. This new guidance allows for either full retrospective adoption or modified retrospective adoption. The FASB deferred the effective date for this new guidance by one year to December 15, 2017 for annual reporting periods beginning after such date. Earlier application of this new guidance is permitted. The Company currently anticipates adopting the guidance in the first quarter of fiscal 2019 using the full retrospective method, reflecting the application of the new standard in each prior reporting period.</font></div><div style="line-height:120%;padding-bottom:0px;padding-top:0px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;padding-bottom:0px;padding-top:0px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In preparation for the implementation and adoption of the new guidance, the Company has established a cross-functional team and implementation plan to identify processes, systems and internal controls over financial reporting impacted by the new guidance. The implementation plan includes comparison of the Company’s historical accounting policies and practices to the requirements of the new guidance, and identifying differences from applying the requirements of the new guidance to the Company’s contracts, consolidated financial statements and related disclosures.</font></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:justify;text-indent:30px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">While the Company’s assessment of the potential impacts of the new guidance is not yet complete, initially the Company believes the most significant impact on the accounting for contracts with customers will be for certain arrangements that include sales of software solutions bundled with post-contract support (PCS) and/or services, where VSOE has not been established for the PCS and/or the services. Due to lack of VSOE under the current guidance, the Company defers recognition of any revenue attributable to such arrangements until the services lacking VSOE are complete. Such revenue is then recognized ratably over the remaining support term. The requirement to have VSOE for undelivered elements to enable the separation of the revenue for delivered software is eliminated under the new guidance and the Company will be required to allocate total contract revenue to each element (referred to as a distinct performance obligation under the new standard) based on either an established or estimated standalone selling price. Accordingly, a portion of the revenue for these types of contracts with customers will be recognized when the software or software solution is transferred to the customer. Dependent on contract-specific terms, the Company expects the actual revenue recognition treatment and timing will vary under the new guidance for some of these arrangements. The Company will continue to evaluate the impact of this new guidance on its consolidated financial statements and related disclosures.</font></div></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 re-measurement of significant foreign currency denominated monetary assets and liabilities. The fair value of these contracts is reflected as other current assets or other current liabilities and the change in fair value of these foreign currency forward contracts is recorded as gain or loss in the Company’s Consolidated Statements of Operations as a component of interest and other income, net. The gain or loss from the change in fair value of these foreign currency forward contracts largely offsets 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, net.</font></div></div>

The Company bases estimates on historical experience and on various assumptions about the future that are believed to be reasonable based on available information. The Company’s reported financial positions 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></div></div>
