Accounting Estimates —

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Such estimates primarily relate to unsettled transactions and events as of the date of the financial statements. Accordingly, actual results may differ from estimated amounts.

Not Yet Adopted

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09 (ASU 2014-09), Revenue from Contracts with Customers. ASU 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605)” and requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14 Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date of ASU 2014-09 to annual reporting periods beginning after December 15, 2017, with earlier application permitted as of annual reporting periods beginning after December 15, 2016. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), to clarify the implementation guidance on principal versus agent. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, providing additional guidance relating to identifying performance obligations under ASU 2014-09 as well as licensing.

The Company is currently in the process of assessing the financial impact of adopting these ASUs and the methods of adoption. The Company currently recognizes subscription license revenue from its Email/Collaboration contracts, which is included within recurring and fee-based revenue, over the life of the contracts (which are typically six months or longer). The Company has concluded that the new guidance will require significantly expanded revenue disclosures, and has tentatively concluded that it is likely that this new guidance will require it to recognize a portion of the revenue from those license contracts upon delivery, at the inception of the contracts, which would have the effect of accelerating recognition of revenue on such contracts, and may have a material impact on the Company’s consolidated financial statements. The standard will be effective for the Company beginning January 1, 2018. The Company will adopt the standard as of its effective date of January 1, 2018. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). The Company has decided to use the latter method.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) which amends lease accounting by lessors and lessees. This new standard will require, among other things, that lessees recognize a right-to-use asset and related lease liability for all significant financing and operating leases, and specifies where in the statement of cash flows the related lease payments are to be presented. The standard is effective for years beginning after December 15, 2018, including interim periods within those years (beginning in calendar year 2019 for the Company), and early adoption is permitted. Adoption of ASU 2016-02 is required to be applied on a modified retrospective basis. The Company is currently in the process of evaluating the impact the adoption of ASU 2016-02 will have on its consolidated financial statements, but currently expects that most of its operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets upon the adoption of ASU 2016-02, which will increase the total assets and total liabilities that it reports as compared to those reported prior to adoption. The Company expects to adopt the standard as of January 1, 2019.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15), which provides guidance related to cash flows presentation and is effective for annual reporting periods beginning after December 15, 2017, subject to early adoption, which is permitted using a retrospective transition approach. ASU 2016-15 is intended to standardize the classification of certain cash receipts and cash payments in the Statement of Cash Flows, and is effective for the Company in its first quarter of fiscal 2018. The Company expects that it will adopt ASU 2016-15 in the first quarter of fiscal 2018 and is currently evaluating the impact of the pending adoption on its consolidated financial statements.

Recently Adopted

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which changes how companies account for certain aspects of stock-based awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as the classification in the statement of cash flows. Effective January 1, 2017, the Company has adopted ASU 2016-09.  The standard eliminated the requirement to defer recognition of excess tax benefits related to employee share-based awards until they are realized through a reduction to income taxes payable.  The Company applied the modified retrospective method, and there was no net cumulative-effect adjustment to retained earnings on January 1, 2017 as the increase of $0.7 million in deferred income tax assets for previously unrecognized excess tax benefits was fully offset by a valuation allowance.  As permitted by the ASU, the Company will continue to use an estimated forfeiture rate in determining stock-based compensation expense.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (Topic 350), to simplify the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test. A goodwill impairment will now be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, limited to the amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for interim and annual periods beginning after December 15, 2019, with early adoption permitted for any impairment tests performed after January 1, 2017. The Company has adopted the new guidance on a prospective basis during the first quarter of 2017. The adoption of this ASU has not impacted the Company’s consolidated financial statements.
