2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Our significant accounting policies are discussed in “Note 2. Summary of Significant Accounting Policies” in our audited consolidated financial statements for the year ended December 31, 2016, included in the Annual Report on Form 10-K that was filed with the SEC on February 21, 2017.

Adoption of New Accounting Pronouncement

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, “Simplifying the Test for Goodwill Impairment (Topic 350)” to simplify the subsequent measurement of goodwill. Under this new guidance, Step 2 of the goodwill impairment test is eliminated, including elimination of the requirement to perform Step 2 for any reporting unit with a zero or negative carrying amount that failed a qualitative assessment. This standard should be applied on a prospective basis with the nature of and reason for the change in accounting principle disclosed upon transition. The standard is effective for us in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We adopted this guidance for the annual goodwill impairment test we performed as of June 30, 2017.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates include income taxes, contingencies, the useful life of property and equipment and intangible assets, the life of our client relationships, the fair value of our stock-based awards and the fair value of our financial instruments, intangible assets and goodwill. These estimates are based on historical experience where applicable and other assumptions that management believes are reasonable under the circumstances. As such, actual results could materially differ from these estimates.

Employee Stock Purchase Plan

An award issued under the Paycom Software, Inc. Employee Stock Purchase Plan (the “ESPP”) is classified as a share-based liability and recorded at the fair value of the award. Expense is recognized, net of estimated forfeitures, on a straight-line basis over the requisite service period.

Funds Held for Clients and Client Funds Obligation

As part of our payroll and tax filing application, we (i) collect client funds to satisfy their respective federal, state and local employment tax obligations, (ii) remit such funds to the appropriate taxing authorities and accounts designated by our clients, and (iii) manage client tax filings and any related correspondence with taxing authorities. During the interval between receipt and disbursement, we invest and earn interest on the amounts that we collect from clients for their federal, state and local employment taxes.

As of June 30, 2017 and December 31, 2016, the funds held for clients were invested in money market funds, demand deposit accounts, commercial paper and certificates of deposit. These investments are shown in the consolidated balance sheets as funds held for clients and are classified as a current asset because the funds are held solely to satisfy the client funds obligation.

The offsetting liability for the tax filings is shown as client funds obligation. The liability is recorded in the accompanying balance sheets at the time we obtain the funds from clients. The client funds obligation represents liabilities that will be repaid within one year of the balance sheet date. As of April 1, 2016, the interest income earned on funds held for clients is recorded in recurring revenues. Prior to April 1, 2016, the interest income earned on these funds was recorded in other income, net in the unaudited consolidated statements of income.

Recently Issued Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”. This authoritative guidance includes a comprehensive new revenue recognition model that requires revenue to be recognized in a manner to depict the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services. The FASB has since issued several additional amendments to this guidance. In April 2015, the FASB proposed a one year deferral of the effective date of the new revenue recognition standard for public and non-public entities reporting under U.S. GAAP and on July 9, 2015, the FASB approved the one year deferral. The effective date of the amended standard will begin in periods beginning after December 15, 2017 and early adoption is permitted but no earlier than for reporting periods beginning after December 31, 2016. The Company has an ongoing project to assess the impact of the standard that has been conducted with the assistance of an international accounting firm. The Company has made significant progress in the assessment phase of this project but has not yet fully determined the impact of the new revenue recognition standard on its systems, processes and consolidated financial statements; however, we expect the new standard will have a material impact on the manner in which we account for certain costs to acquire new contracts (i.e., selling and commission costs) and costs to fulfill contracts (i.e., costs related to implementation services performed). Generally, as it relates to these types of costs, the provisions of the new standard will result in the deferral of these costs on the consolidated balance sheets and subsequently the amortizing of these costs to the consolidated statements of income over the expected life of our client relationships, which we have determined to be an average of 10 years. The Company is still evaluating whether implementation services contain an implied performance obligation in the form of a material right to the customer and if so, what impact that would have on the recognition of implementation revenues. We expect to complete our assessment process, including selecting a transition method for adoption, by the end of the third quarter of 2017 and will complete our implementation process prior to the adoption of this ASU on January 1, 2018.

In February 2016, the FASB issued ASU No. 2016-02 “Leases (Topic 842).” The purpose of the guidance is to increase the transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet as well as providing additional disclosure requirements related to leasing arrangements. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, though early adoption is permitted. Full retrospective application is prohibited. We are in the preliminary stages of gathering data and assessing the impact of the new lease standard, however, we anticipate that the adoption of this accounting standard will materially affect our consolidated balance sheets and may require changes to the system and processes that we use to account for leases. We have not yet made any decision on the timing of adoption or method of adoption with respect to the optional practical expedients.
