RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS In January 2017, the Financial Accounting Standards Board issued an accounting standard update on the accounting for business combinations by clarifying the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The new guidance is effective for annual and interim periods beginning after December 15, 2017. The Company is currently evaluating the potential impact of this standard on its financial position and results of operations. In October 2016, the Financial Accounting Standards Board issued an accounting standard update on the accounting for income taxes, which requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transaction occurs as opposed to deferring tax consequences and amortizing them into future periods. This update is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. A modified retrospective approach with a cumulative-effect adjustment directly to retained earnings at the beginning of the period of adoption is required. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial position or results of operations. In March 2016, the Financial Accounting Standards Board issued an accounting standard update on the accounting for stock-based compensation. The guidance requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase more of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. The Company adopted this standard effective January 1, 2017. The impact of the adoption on the condensed consolidated financial statements was as follows: •Income tax accounting - The Company adopted the guidance related to the recognition of excess tax benefits and deficiencies as income tax expense or benefit in the Company's condensed consolidated statements of income on a prospective basis. The Company adopted on a modified retrospective basis the recognition of previously unrecognized excess tax benefits and recorded the cumulative effect of the change as a $0.4 million increase to Retained earnings with a corresponding adjustment to Deferred tax assets, net as of January 1, 2017. •Forfeitures - The Company elected to account for forfeitures as they occur on a modified retrospective basis, rather than estimate expected forfeitures and recorded the cumulative effect of the change as a $5.7 million decrease to Retained earnings as of January 1, 2017 with a corresponding adjustment to Additional paid-in capital. •Cash flow presentation - The Company elected to adopt the guidance related to the presentation of excess tax benefits in the condensed consolidated statements of cash flows on a prospective basis. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to any of the periods presented on the Company's condensed consolidated statements of cash flows since such cash flows have historically been presented as a financing activity. In February 2016, the Financial Accounting Standards Board issued an accounting standard update on the accounting of leases. The new guidance requires that lessees in a leasing arrangement recognize a right-of-use asset and a lease liability for most leases (other than leases that meet the definition of a short-term lease). The liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, such as for initial direct costs. The new guidance is effective for annual reporting periods beginning after December 15, 2018. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. The Company is currently evaluating the potential impact of this standard on its financial position and results of operations; however, it is expected to have a material impact due to the recognition of the right-of-use assets and lease liabilities for operating leases which are currently not reflected on the balance sheet. In July 2015, the Financial Accounting Standards Board issued an accounting standard update modifying the accounting for inventory. Under the new guidance, the measurement principle for inventory will change from lower of cost or market value to lower of cost and net realizable value. The standard defines net realizable value as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The standard is applicable to inventory that is accounted for under the first-in, first-out method and is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years, with early adoption permitted. The Company adopted this standard effective January 1, 2017. The adoption of this guidance did not have a significant impact on the Company’s financial position or results of operations. In May 2014, the Financial Accounting Standards Board issued an accounting standard update on revenue recognition. The new guidance creates a single, principle-based model for revenue recognition and expands and improves disclosures about revenue. In July 2015, the Financial Accounting Standards Board issued an accounting standard update that defers the effective date of the new revenue recognition standard by one year. The new guidance is effective for annual reporting periods beginning on or after December 15, 2017, and must be adopted using either a full retrospective approach for all periods presented in the period of adoption or a modified retrospective approach. The Company has completed its assessment of its information technology systems, data and processes related to the implementation of this accounting standard. Additionally, the Company has substantially completed its information technology system design and solution development, and commenced implementation of the solution in the first quarter of fiscal year 2017. The Company is currently evaluating and developing internal controls during implementation to ensure its portfolio of contracts are adequately evaluated, and it expects that the adoption of the standard will have a significant impact to its internal control environment. The Company's internal controls will be modified and augmented, as necessary, upon adoption of the Company’s new revenue recognition policy effective January 1, 2018. The Company expects to adopt the accounting standard update on a modified retrospective basis in the first quarter of fiscal year 2018, and is currently evaluating the potential impact of this standard on its financial position and results of operations. Under the new standard the Company expects to capitalize and amortize certain commissions over the expected customer life rather than expensing them as incurred. Additionally, under the new standard, the Company would be required to recognize term license revenues upfront at time of delivery rather than ratably over the related contract period. The Company expects revenue recognition related to perpetual software, hardware, cloud offerings and professional services to remain substantially unchanged.
