THE ULTIMATE SOFTWARE GROUP, INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.Nature of Operations

Ultimate's UltiPro product suite (“UltiPro”) is a comprehensive, engaging solution that has human resources ("HR"), payroll, and benefits management at its core and includes global people management, available in twelve languages with more than 35 country-specific localizations. The solution is delivered via software-as-a-service to organizations based in the United States and Canada, including those with global workforces. UltiPro is designed to deliver the functionality businesses need to manage the complete employment life cycle from recruitment to retirement. We market our UltiPro solutions primarily to global enterprise companies, which we define as companiesorganizations with 2,501 or more than 2,500 employees, including those with 10,000 or more employees; enterprise companies, which we define as those having 1,501-2,500 employees; mid-market companies, which we define as those having 501-1,500501-2,500 employees; and strategic market companies, which we define as those having 300-500100-500 employees. UltiPro is marketed primarily through our global enterprise, enterprise, mid-market and strategic direct sales teams.
2.Basis of Presentation, Consolidation and the Use of Estimates
The accompanying unaudited condensed consolidated financial statements of Ultimate have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The information in this quarterly report should be read in conjunction with Ultimate’s audited consolidated financial statements and notes thereto included in Ultimate’s Annual Report on Form 10-K for the fiscal year ended December 31, 20152016 filed with the SEC on February 26, 201624, 2017 (the “Form 10-K”).
The unaudited condensed consolidated financial statements included herein reflect all adjustments (consisting only of normal, recurring adjustments) which are, in the opinion of Ultimate’s management, necessary for a fair presentation of the information for the periods presented. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Interim results of operations for the three and six months ended June 30, 20162017 are not necessarily indicative of operating results for the full fiscal year or for any future periods.
The unaudited condensed consolidated financial statements reflect the financial position and operating results of Ultimate and include its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.
3.Summary of Significant Accounting Policies and Recent Accounting Pronouncements
Summary of Significant Accounting Policies
Ultimate’s significant accounting policies discussed in Note 3 to its audited consolidated financial statements for the fiscal year ended December 31, 2015,2016, included in the Form 10-K, have not significantly changed.
In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2016-09, “Improvements to Employee Share-Based Payment Accounting(“ASU 2016-09”). The standard amends the accounting for certain aspects of share-based payments to employees. We elected to early adopt the new guidance in the third quarter of fiscal year 2016. Therefore, the prior year numbers in our unaudited condensed consolidated statements of income, our unaudited condensed consolidated statements of comprehensive income, our unaudited condensed consolidated statement of cash flows, our non-GAAP financial measures and our notes to unaudited condensed financial statements reflect revised numbers in accordance with the adoption of this guidance. Our unaudited condensed consolidated balance sheets were not impacted.
Fair Value of Financial Instruments
Ultimate's financial instruments, consisting of cash and cash equivalents, investments in marketable securities, funds held for clientscustomers and the related obligations, accounts receivable, accounts payable, capital lease obligations and other borrowings,long-term liabilities, approximated fair value (due to their relatively short maturity) as of June 30, 20162017 and December 31, 2015.2016.

Recently Issued Accounting Standards
In May 2014, the Financial Accounting Standards Board (“FASB”)FASB issued Accounting Standards Update (“ASU”)ASU 2014-09, Revenue from Contracts with Customers (Topic("Topic 606)"”. ("Topic 606 supersedes the revenue requirements in ASU 2014-09"Topic 605, Revenue Recognition ("Topic 605"), which and requires an entity to recognize the amountrecognition of revenue to which it expects to be entitled for the transfer ofrevenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services and includes Subtopic 340-40, Other Assets and Deferred Costs - Contracts with Customers, which discusses the deferral if incremental costs of obtaining a contract with a customer, including the period of amortization of such costs. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 will replace most existingCollectively, we refer to Topic 606 and Subtopic 340-40 as the "new standard". Topic 606 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition guidanceprocess than are required under existing GAAP, including identifying performance obligations in U.S. GAAP when it becomes effective. In August 2015, the FASB issued ASU 2015-14, contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation, among others."Revenue from Contracts with Customers: Deferral
We began assessing the new standard in 2016 and have continued our assessment during the first half of 2017 to address the potential impact that Topic 606 could have on our unaudited condensed consolidated financial statements and the required resources to implement the new standard. Our assessment of the Effective Date" ("ASU 2015-14"), which defersimpact included an evaluation of the effective datefive step process along with the enhancement of ASU 2014-09 for all entities by one year. Under ASU 2015-14,disclosures that will be required under the new standard. We have developed our initial plan for implementing the new standard, which includes, but is not limited to, identifying contract populations and "in scope" customer contracts, identifying performance obligations in those customer contracts, and evaluating any impact of variable consideration. Our assessment also includes determining the impact the new standard may have on the revenue reporting processes, including disclosures, ensuring internal controls will operate effectively with the new standard and performing gap analyses on collected data and determining the relative accounting positions where applicable. Included in our assessment of the new standard, we will focus on the potential impact on sales commissions and the term over which they will amortize.
We anticipate this standard will not have a material impact on the way we recognize revenues. The new standard will require us to defer incremental commission costs to obtain related subscription contracts over the period of benefit. While we are still assessing the period of benefit, we have concluded that it will be longer than the amortization period under existing GAAP. Under current GAAP, we defer only direct and incremental commission costs to obtain a contract and amortize those costs over the term of the related subscription contract, which is generally 2-3 years. We are still evaluating the overall effect the standard will have on the unaudited condensed consolidated financial statements and related disclosures.
Topic 606 is effective for Ultimate on January 1, 2018. Early adoption will2018 using either of two transition methods including several practical expedients: (1) full retrospective method, in which the new standard would be permitted, but not beforeapplied to each prior reporting period presented or (2) the original effectivemodified retrospective method, in which the cumulative effect of initially applying the new standard would be recognized at the date of January 1, 2017. The standard permitsinitial application and providing certain additional disclosures as defined per the use of either the retrospective or cumulative effect transition method. In March 2016, the FASB issued

ASU 2016-08, "Principal versus Agent Considerations (Reporting Revenue Gross versus Net)" ("ASU 2016-08"), in April 2016, the FASB issued ASU 2016-10, "Identifying Performance Obligations and Licensing" ("ASU 2016-10"), and in May 2016, the FASB issued ASU 2016-12, "Narrow-Scope Improvements and Practical Expedients", all which clarify the guidance in ASU 2014-09 and have the same effective dates as the originalnew standard. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We haveUltimate has not yet selected a transition method and have not determined the effect the standard will have on our ongoing financial reporting.
In April 2015, the FASB issued ASU 2015-05, “Customer's Accounting for Fees Paid in a Cloud Computing Arrangement" ("ASU 2015-05"), which requires that if a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. Further, it requires that if a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. ASU 2015-05 will not change GAAP for a customer’s accounting for service contracts. In addition, ASU 2015-05 supersedes paragraph 350-40-25-16. Consequently, all software licenses within the scope of subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. The new standard became effective for Ultimate on January 1, 2016. The standard permits the use of either the prospective or retrospective method. The effect of the adoption of ASU 2015-05 has had no material impact on our ongoing financial reporting.
In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): "Balance Sheet Classification of Deferred Taxes" ("ASU 2015-17”). ASU 2015-17 requires entities to offset all deferred tax assets and liabilities (and valuation allowances) for each tax-paying jurisdiction within each tax-paying component and present the net deferred tax as a single noncurrent amount in a classified balance sheet. The new standard is effective for Ultimate on January 1, 2017 and early adoption is permitted. The standard permits the use of either the prospective or retrospective method. We are evaluating the effect that ASU 2015-17 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method.
In February 2016, the FASB issued ASU 2016-02, "Leases" ("ASU 2016-02"), to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The new standard is effective for Ultimate on January 1, 2019 and early adoption is permitted. The standard requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. We are evaluating the effect that ASU 2016-02 will have on our unaudited condensed consolidated financial statements and related disclosures. We have not yet determined the effect the standard will have on our ongoing financial reporting.
Recently Adopted Accounting Standards
In March 2016,November 2015, the FASB issued ASU 2016-09,2015-17, Income Taxes (Topic 740): "Improvements to Employee Share-Based Payment Accounting"Balance Sheet Classification of Deferred Taxes" ("ASU 2016-09"2015-17”). The standard is intendedASU 2015-17 requires entities to simplify several areas of accountingoffset all deferred tax assets and liabilities (and valuation allowances) for share-based compensation arrangements, includingeach tax-paying jurisdiction within each tax-paying component and present the incomenet deferred tax impact, classification on the statement of cash flows and forfeitures. The new standard is effective for Ultimate onas a single noncurrent amount in a classified balance sheet. Effective January 1, 2017 the Company adopted ASU 2015-17. Subsequent to adoption, all deferred tax assets and early adoption is permitted. The standard requires transition for specific objectives of the standard. Amendments related to the timing of when excessdeferred tax benefitsliabilities are recognized, minimum statutory withholding requirements, forfeitures, and intrinsic value should be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equitypresented as of the beginning of the period in which the guidance is adopted. Amendments related to the presentation of employee taxes paidnoncurrent on the statementbalance sheet. The changes have been applied prospectively as permitted by the ASU and prior years have not been restated. The adoption of cash flows when an employer withholds shares to meet the minimum statutory withholding requirement should be applied retrospectively. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement and the practical expedient for estimating expected term should be applied prospectively. Further, an entity may elect to apply the amendments related to the presentation of excess tax benefitsthis ASU does not have a material effect on the statementCompany's results of cash flows using either a prospective transition methodoperations, financial condition or a retrospective transition method.

Business Combinations
2016 Business Combinations
In the second quarter of 2016, we completed the acquisition of substantially all of the assets of Capital Analytics, Inc. (d/b/a Vestrics) (hereinafter referred to as "Vestrics") (the “Vestrics Acquisition”), a Delaware limited liability company located in North Carolina. The acquisition was deemed insignificant to the consolidated financial statements.
Acquisition of Capital Analytics, Inc.
On May 11, 2016 (the "Vestrics Closing Date"), pursuant to an asset purchase agreement with Vestrics, we acquired certain assets and liabilities in exchange for $10.1 million, of which $9.1 million was paid in cash during the three months ended June 30, 2016 and the remaining $1.0 million is being held in escrow and is included in accrued liabilities on our

unaudited condensed consolidated balance sheet. We recorded the Vestrics Acquisition using the acquisition method of accounting and recognized assets and liabilities assumed at their fair value as of the date of acquisition. Based on the preliminary valuation of Vestrics, the significant classes of assets and liabilities to which we allocated the purchase price were goodwill of $4.3 million (which includes working capital, net, totaling $0.2 million, which was assumed pursuant to the Vestrics Acquisition) and identifiable intangible assets of $6.0 million related to developed technology. Vestrics’ predictive technology enables a company to identify and analyze the connections between its investments in human capital and the performance-related business results of those investments. We will leverage Vestrics’ technology as we continue to expand our analytics capabilities across UltiPro. The fair value of the acquired developed technology was estimated using the cost approach. Identifiable intangible assets were assigned a total weighted-average amortization period of 7.0 years. Since the developed predictive technology acquired pursuant to the Vestrics Acquisition will be included in the development project currently being capitalized as internal-use software to be offered as a cloud product in the future, amortization of the Vestrics developed technology will begin when it is ready for its intended use.
The results of operations from this acquisition have been included in our unaudited condensed consolidated financial statements since the Vestrics Closing Date. Pro forma results of operations have not been presented because the effects of this business combination were not significant to our unaudited condensed consolidated results of operations.
5.    Funds held for Customers, Corporate Investments in Marketable Securities and Fair Value of Financial Instruments
We classify our investments in marketable securities with readily determinable fair values as available-for-sale. Available-for-sale securities consist of debt and equity securities not classified as trading securities or as securities to be

held to maturity. Unrealized gains and losses, net of tax, on available-for-sale securities are reported as a net amount in accumulated other comprehensive loss in stockholders’ equity until realized. Realized gains and losses resulting from available-for-sale securities are included in other income, net, in the unaudited condensed consolidated statements of income. There were no significant reclassifications of realized gains and losses on available-for-sale securities to the unaudited condensed consolidated statements of income for the three and six months ended June 30, 20162017 and June 30, 2015.2016.
Gains and losses on the sale of available-for-sale securities are determined using the specific identification method.   There was $154$469 thousand of net unrealized gainloss and $84$145 thousand of net unrealized loss on available-for-sale securities as of June 30, 20162017 and December 31, 2015,2016, respectively.

We classify and disclose fair value measurements in one of the following three categories of fair value hierarchy:
Level 1 -Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets and liabilities.
Level 2 -Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly.
Level 3 -Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.
A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
Our assets that are measured by management at fair value on a recurring basis are generally classified within Level 1 or Level 2 of the fair value hierarchy. The types of instruments valued, based on quoted market pricesWe have had assets in active markets, include certificates of deposit. Such instruments are generallythe past, and may have assets in the future, classified within Level 1 of the fair value hierarchy. No assets or investments were classified within Level 1 of the fair value hierarchy as of June 30, 2017 or as of December 31, 2016. We did not have any transfers into and out of Level 1 or Level 2 during the three and six months ended June 30, 20162017 or the twelve months ended December 31, 2015.2016. No assets or investments were classified as Level 3 as of June 30, 20162017 or as of December 31, 2015.2016.

The types of instruments valued by management, based on quoted prices in less active markets, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency, include corporate debentures and bonds, commercial paper, U.S. agency bonds and U.S. Treasury bills and asset-backed securities owned by Ultimate. Such instruments are generally classified within Level 2 of the fair value hierarchy. Ultimate uses consensus pricing, which is based on multiple pricing sources, to value its fixed income investments. The following table sets forth, by level within the fair value hierarchy, financial assets accounted for at fair value as of June 30, 20162017 and December 31, 20152016 (in thousands):

6.5.Property and Equipment
Property and equipment are stated at cost, net of accumulated depreciation and amortization. Property and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, which range from 2 to 15 years. Leasehold improvements and assets under capital leases are amortized over the shorter of the estimated useful life of the asset or the term of the lease, which range from 3 to 15 years. Maintenance and repairs are charged to expense when incurred; betterments are capitalized. Upon the sale or retirement of assets, the cost, accumulated depreciation and amortization are removed from the accounts and any gain or loss is recognized.
Property and equipment as of June 30, 20162017 and December 31, 20152016 consist of the following (in thousands):

We capitalize computer software development costs related to software developed for internal use in accordance with Accounting Standards Codification ("ASC") Topic 350-40, Intangibles Goodwill and Other-Internal Use Software. During the three and six months ended June 30, 2016,2017, we capitalized $9.0$13.6 million and $17.0$26.2 million , respectively, of computer software development costs related to a development project to be sold in the future as a cloud product only (the "Development Project"). There were $6.3$9.0 million and $12.8$17.0 million of software development costs related to the Development Project which were capitalized in the three and six months ended June 30, 2015,2016, respectively. For the three and six months ended June 30, 20162017 and June 30, 2015,2016, these capitalized costs were primarily direct labor costs. As a component of these direct labor costs we capitalized $1.0 million and $2.0 million of stock-based compensation costs during the three and six months ended June 30, 2017, respectively. During the three and six months ended June 30, 2016, we capitalized $1.0 million and $2.0 million, respectively, of stock-based compensation costs. These capitalized costs are included with internal-use software in property and equipment in the unaudited condensed consolidated balance sheet and purchases of property and equipment in the unaudited condensed consolidated statements of cash flows. Internal-use software is amortized on a straight-line basis over its estimated

useful life, commencing after the software development is substantially complete and the software is ready for its intended use. At each balance sheet date, we evaluate the useful lives of these assets and test for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. During the

three and six months ended June 30, 2017 there were $1.0 million and $2.0 million, respectively, of amortization associated with certain product modules of the Development Project which were ready for their intended use. During the three and six months ended June 30, 2016 and June 30, 2015, there waswere $0.3 million and $0.5 million, respectively, of amortization associated with a particularcertain product module, Recruitment,modules of the Development Project which waswere ready for itstheir intended use during the second quarter of 2014.use. The amortization of capitalized software (e.g., from the Recruitment release) is included in cost of recurring revenues.

8.7.Goodwill and Intangible Assets
Goodwill
Goodwill represents the excess of cost over the net tangible and identifiable intangible assets of acquired businesses. Goodwill amounts are not amortized, but rather tested for impairment at least annually. Identifiable intangible assets acquired in business combinations are recorded based upon fair value at the date of acquisition and amortized over their estimated useful lives.
The changes in the carrying value of goodwill since December 31, 20152016 were as follows (in thousands):

(1) Represents the impact of the foreign currency translation of the portion of acquired intangible assets that is recorded by our Canadian subsidiary whose functional currency is also its local currency. Such intangible assets are translated into U.S. dollars using exchange rates in effect at period end. Adjustments related to foreign currency translation are included in other comprehensive income (loss).
Acquired intangible assets are amortized over their estimated useful life, generally three to ten years, in a manner that reflects the pattern in which the economic benefits are consumed. Included in acquired intangible assets as of June 30, 2017 and December 31, 2016, were $0.1 million of assets with indefinite lives. Amortization expense for acquired intangible assets was $257 thousand$0.8 million and $504 thousand$1.6 million for the three and six months ended June 30, 2017, respectively, and $0.3 million and $0.5 million for the three and six months ended June 30, 2016, respectively, and $264 thousand and $528 thousand for the three and six months ended June 30, 2015, respectively.
9.8.Earnings Per Share
Basic earnings per share is computed by dividing income available to common stockholders (the numerator) by the weighted average number of common shares outstanding (the denominator) for the period. The computation of diluted earnings per share is similar to basic earnings per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common shares had been issued.

The following table is a reconciliation of the shares of Ultimate's issued and outstanding $0.01 par value common stock ("Common Stock") used in the computation of basic and diluted net income per share for the three and six months ended June 30, 20162017 and 20152016 (in thousands):

10.9.Foreign Currency
The financial statements of Ultimate’s foreign subsidiary, The Ultimate Software Group of Canada, Inc. (“Ultimate Canada”), have been translated into U.S. dollars. The functional currency of Ultimate Canada is the Canadian dollar. Assets and liabilities are translated into U.S. dollars at period-end exchange rates. Income and expenses are translated at the average exchange rate for the reporting period. The resulting translation adjustments, representing unrealized gains or losses, are included in accumulated other comprehensive loss, a component of stockholders’ equity. Realized gains and losses resulting from foreign exchange transactions are included in total operating expenses in the unaudited condensed consolidated statements of income. There were no significant reclassifications of realized gains and losses resulting from foreign exchange transactions to the unaudited condensed consolidated statements of income for the three and six months ended June 30, 20162017 and June 30, 2015.2016.
For the three and six months ended June 30, 2017, Ultimate had unrealized translation gains of $0.4 million and $0.6 million, respectively. For the three and six months ended June 30, 2016, Ultimate had unrealized translation gains of $0.1 million and $1.5 million, respectively. For the three and six months ended June 30, 2015, Ultimate had an unrealized translation gain of $0.5 million and an unrealized translation loss of $1.5 million, respectively. Included in accumulated other comprehensive loss, as presented in the accompanying unaudited condensed consolidated balance sheets, are cumulative unrealized translation losses of $6.3 million as of June 30, 20162017 and $7.8$6.9 million as of December 31, 2015.2016.
11.10.Stock-Based Compensation
Summary of Plans
Our Amended and Restated 2005 Equity and Incentive Plan (the “Plan”) authorizes the grant of options (“Options”) to non-employee directors, officers and employees of Ultimate to purchase shares of Common Stock.  The Plan also authorizes the grant to such persons of restricted and non-restricted shares of Common Stock, stock appreciation rights, stock units and cash performance awards (collectively, together with the Options, the “Awards”).
At the 2016 Annual Meeting of Stockholders, held on May 16, 2016 (the “2016 Annual Meeting”), the stockholders of Ultimate approved the Plan, including an amendment to increase the number of shares of our Common Stock authorized for issuance pursuant to Awards granted under the Plan by 1,090,000 shares. As of June 30, 2016,2017, the aggregate number of shares of Common Stock that were available to be issued under all Awards granted under the Plan was 1,129,085705,353 shares. A complete copy of the Plan is contained in Ultimate's Form 8-K that was filed with the SEC on May 17, 2016.

ITEM 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion of the financial condition and results of operations of The Ultimate Software Group, Inc. and its subsidiaries (“Ultimate,” “we,” “us,” or “our”) should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto included elsewhere in this Quarterly Report on Form 10-Q (this “Form 10-Q”) and in conjunction with Ultimate’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015,2016, filed with the Securities and Exchange Commission (the “SEC”) on February 26, 201624, 2017 (the “Form 10-K”).
Business Overview
Ultimate Software is a leading cloud provider of people management solutions, often referred to as human capital management (“HCM”). solutions with more than 33 million people records in our HCM cloud. Ultimate's UltiPro product suite (“UltiPro”) is a comprehensive, engaging solution that hasincludes human resources ("HR"(“HR”), payroll, talent, and benefitstime and labor management at its core andsolutions that connect people with the information they need to work more effectively. UltiPro also includes global people management, and is available in twelve languages with more than 35 country-specific localizations. The solution is delivered primarily via software-as-a-service ("SaaS") to organizations based in the United States and Canada, including those with global workforces. As of June 30, 2016,2017, we hadhave more than 3,400 organizations as3,700 customers and approximately 30 million people recordswith employees in our HCM cloud.160 countries. We attained our leadership position, we believe, through our focus on unified HCM, people-centric product design, cloud technology, and strong customer relationships.
UltiPro is designed to deliver the functionality businesses need to manage the complete employee life cycle from recruitment to retirement and to facilitate employee engagement with their employers and each other. The solution includes unified feature sets for talent acquisition and onboarding, HR management and compliance, benefits management and online enrollment, payroll, performance management, compensation management with salary planning, budgeting and development of incentive plans, succession management, reporting and analytical decision-making and predictive tools, and time and attendance. UltiPro has role-based features for HR professionals, executives, managers, administrators, and employees whether they are in or out of the office, including access to business-critical information on mobile devices such as the iPhone, iPad, and other smartphones and tablets.
Our customers tell us that UltiPro helps them to streamline talent management, HR and payroll processes to significantly reduce administrative and operational costs while also empowering them to manage the talent in their workforces more strategically. UltiPro provides our customers with tools to analyze workforce trends for better decision making, identify high-performing talent within their organizations, predict who high-performers will be with a high degree of accuracy, find critical information quickly and perform routine business activities efficiently.
Our cloud offering of UltiPro provides Web-based access to comprehensive HCM functionality for organizations that want to simplify delivery and support of their business applications. We have found that UltiPro is attractive to companies that want to focus on their core competencies to increase sales and profits. Through UltiPro, we supply and manage the hardware, infrastructure, ongoing maintenance and backup services for our customers. Customer systems are currently managed at four data centers--one located near Atlanta, Georgia, one near Phoenix, Arizona, one near Toronto, Canada, and another near Vancouver, Canada. All data centers are owned and operated by independent third parties.
We market our UltiPro solutions primarily to global enterprise companies, which we define as companiesorganizations with 2,501 or more than 2,500 employees, including those with 10,000 or more employees; enterprise companies, which we define as those having 1,501-2,500 employees; mid-market companies, which we define as those having 501-1,500501-2,500 employees; and strategic market companies, which we define as those having 300-500100-500 employees. UltiPro is marketed primarily through our enterprise, mid-market and strategic direct sales teams. Our mid-market and strategic market customers have access to nearly all the features that our larger enterprise companies have through UltiPro, plus a bundled services package. Since many companies in the mid- and strategic markets do not have information technology (“IT”) staff on their premises to help with system deployment or ongoing management issues, we have created a bundled services package to give these customers a high degree of convenience by handling system configuration, business rules, and other situations for them “behind the scenes.” UltiPro is marketed primarily through our global enterprise, enterprise, mid-market and strategic direct sales teams.
In addition to UltiPro's HCM functionality, our customers have the option to purchase a number of additional capabilities on a per-employee-per-month (“PEPM”) basis, which are available to enhance and complement the core functionality of UltiPro and which are based on the particular business needs of our customers. These optional UltiPro capabilities currently include (i) the talent acquisition suite (recruitment and onboarding); (ii) the talent management suite (performance management, talent predictors, and succession management); (iii) learning management; (iv) employee engagement surveys; (v) compensation management; (iv)(vi) benefits enrollment; (v)(vii) time management; (vi) Select Services which include(viii) payment services (formerly referred to as “tax filing”), managed services and other specific-need services such as filing Affordable Care Act ("ACA") compliance documents for customers; (vii); (ix) wage attachments; and (viii)(x) other optional features (collectively, “Optional Capabilities”).

, which are described below.
In the fall of 2015, Ultimate began deploying an ACAa Patient Protection and Affordable Care Act ("ACA") toolkit that enablesenabled our customers to comply with ACA regulations by the 2016 deadline. The toolkit is embedded in UltiPro and

automatically populates the Forms 1094-C and 1095-C with the appropriate information. In addition, Ultimate offers our customers additional optional ACA-related services, branded UltiPro ACA Employer Services. These include such services as printing and electronic filing of 1094-C and 1095-C forms with the IRS on our customer’s behalf and on-going proactive monitoring and managing of employee eligibility alerts, notices, and penalty responses. UltiPro’s tracking of hours worked in payroll ties to UltiPro’s benefits management, enabling automatic calculation of employees’ hours of service eligibility and providing HR leaders analytical insight into compliance risk related to the ACA delivered in the Healthcare Eligibility Dashboard and via our UltiPro ACA Toolkit.
All Optional Capabilities are priced solely on a subscription basis. Some of the Optional Capabilities are available to global enterprise, enterprise, mid-market and strategic market customers while others are available exclusively to either global enterprise, enterprise, mid-market or strategic market customers, and availability is based on the needs of the respective customers, the number of their employees and the complexity of their HCM environment.
The key drivers of our business are (i) growth in recurring revenues; (ii) operating income, excluding non-cash stock-based compensation and amortization of acquired intangibles ("Non-GAAP Operating Income"); and (iii) retention of our customers once our solutions are sold (“Customer Retention”). For the three months ended June 30, 2016,2017, our (i) recurring revenues grew by 27.4%23.1%, compared with the same period in 2015,2016, and (ii) Non-GAAP Operating Income was $37.4$47.0 million, or 20.0%20.9% of total revenues, as compared with $29.7$37.4 million, or 20.2%20.0% of total revenues, for the same period in 2015.2016. For the six months ended June 30, 2016,2017, our (i) recurring revenues grew by 27.8%23.7%, compared with the same period in 2015,2016, and (ii) Non-GAAP Operating Income was $73.4$84.7 million, or 19.6%18.7% of total revenues, as compared with $55.8$73.4 million, or 19.1%19.6% of total revenues, for the same period in 2015.2016. As of June 30, 2016,2017, our Customer Retention, on a trailing twelve-month basis, exceeded 97%was approximately 96% for our recurring revenue cloud customer base, which compares with greater than 96% for the prior year.base. See “Non-GAAP Financial Measures” below.
Our ability to achieve significant revenue growth in the future will depend upon the success of our direct sales force and our ability to adapt our sales efforts to address the evolving markets for our products and services. We provide our sales personnel with comprehensive and continuing training with respect to technology and market place developments. Aside from sales commissions, we also provide various incentives to encourage our sales representatives, including stock-based compensation awards based upon performance.
The HCM market is intensely competitive. We address competitive pressures through improvements and enhancements to our products and services, the development of additional features of UltiPro and a comprehensive marketing team and process that distinguishes Ultimate and its products from the competition.  Our focus on customer service, which enables us to maintain a high Customer Retention rate, also helps us address competitive pressures.
As our business has grown, we have become increasingly subject to the risks arising from adverse changes in domestic and global economic conditions. If general economic conditions were to deteriorate, we may experience delays in our sales cycles, increased pressure from prospective customers to offer discounts and increased pressure from existing customers to renew expiring recurring revenue agreements for lower amounts. We address continuing economic pressures by, among other things, efforts to control growth of our operating expenses through the monitoring of controllable costs and vendor negotiations.
Ultimate has two primary revenue sources: recurring revenues and services revenues. The primary component of recurring revenues is subscription revenues from our cloud offering of UltiPro. The majority of services revenues are derived from implementation consulting services.
As cloud units are sold, the recurring revenue backlog associated with UltiPro grows, enhancing the predictability of future revenue streams. Cloud revenues include ongoing monthly subscription fees, priced on a PEPM basis. Revenue recognition for our recurring revenue stream is typically triggered when the customer processes its first payroll using UltiPro (or goes “Live”).
Acquisitions
On May 11, 2016, we acquired certain assets and assumed certain liabilities of Capital Analytics, Inc., (d/b/a Vestrics), (the “Vestrics Acquisition”), a Delaware corporation located in North Carolina. Vestrics’ predictive technology enables a company to identify and analyze the connections between its investments in human capital and the performance-related business results of those investments. We will leverage Vestrics’ technology as we continue to expand our analytics capabilities across UltiPro. See Note 4 of the Notes to Unaudited Condensed Consolidated Financial Statements.


Critical Accounting Estimates
The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.  Ultimate’s critical accounting estimates, as discussed in "Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations," included in the Form 10-K, have not significantly changed.

Fair Value of Financial Instruments
Ultimate's financial instruments, consisting of cash and cash equivalents, investments in marketable securities, funds held for customers and the related obligations, accounts receivable, accounts payable, capital lease obligations and other borrowingslong-term liabilities approximated fair value (due to their relatively short maturity) as of June 30, 20162017 and December 31, 2015.2016.

Overview of Financial Results
In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting(“ASU 2016-09”). The standard amends the accounting for certain aspects of share-based payments to employees. We elected to early adopt the new guidance in the third quarter of fiscal year 2016. Therefore, the prior year numbers in our unaudited condensed consolidated statements of income, our unaudited condensed consolidated statements of comprehensive income, our unaudited condensed consolidated statement of cash flows, our non-GAAP financial measures and notes to unaudited condensed financial statements reflect revised numbers in accordance with the adoption of this guidance. Our unaudited condensed consolidated balance sheets were not impacted.
For the three and six months ended June 30, 2016,2017, compared with the three and six months ended June 30, 2015,2016, total revenues increased by $39.3$38.2 million and $81.6$79.4 million, respectively, and the combination of our total cost of revenues and operating expenses ("Total Costs") increased by $38.5$39.7 million and $81.2$87.2 million, respectively, resulting in an increasea decrease in our operating income of $0.8$1.5 million and $0.4$7.8 million, respectively. The increases in the Total Costs for the three and six months ended June 30, 2017 included the impact of $10.6 million and $18.1 million, respectively, of non-cash stock-based compensation, discussed below.
During the three and six months ended June 30, 2016,2017, as compared with the same periods in 2015,2016, our non-cash stock-based compensation expense increased $6.9$10.6 million and $17.2$18.1 million, respectively, primarily as the result of changes we made with respect to our change in control plans ("CIC Plans") for certain senior officers. As part of an on-going comprehensive review of the senior officer compensation arrangements, the Board of Directors and the Compensation Committee took actions to modify and terminate the CIC Plans primarily to better align management's incentives with long-term value creation for our shareholders, by significantly amending the CIC Plan I (in March 2015 and February 2016) and terminating the CIC Plan I (in February 2017), which covers Mr. Scott Scherr, our Chairman of the Board, President and Chief Executive Officer, Mr. Marc D. Scherr, our Vice Chairman of the Board and Chief Operating Officer, and Mr. Mitchell K. Dauerman, our Executive Vice President, Chief Financial Officer and Treasurer, and terminating our CIC Plan II (in March 2015), which covered eight other senior officers of the Company (collectively, the "CIC Plan Revisions"). The CIC Plans were designed to provide cash payments to senior officers covered by the respective plans upon a “change in control” of Ultimate Software. The change in control plans were originally established in 2004 in lieu of granting time-based equity awards, and they were amended in 2007 to increase the size of the change in control awards, again in lieu of granting time-based equity awards. Under the terms of each of the CIC Plans, we were required to provide each covered senior officer with “comparable value” with respect to the reduction or termination of his or her change in control award. The comparable value given to each such senior officer was in the form of a restricted stock award. These restricted stock awards granted in March 2015, February 2016 and February 20162017, in connection with the CIC Plan Revisions accounted for $4.1$5.8 million of the $6.9$10.6 million increase in our non-cash stock-based compensation expense for the three months ended June 30, 20162017 and $11.5$10.5 million of the $17.2$18.1 million increase in our non-cash stock-based compensation expense for the six months ended June 30, 2016.2017.
Also included in the non-cash stock-based compensation expense increase in 20162017 were the effects of new grants in the yearperiod and the impact of changes in our stock price.
Stock-based compensation expense and stock-based compensation expense associated with the CIC Revisions as discussed above are as follows (in thousands):

Revenues
Our revenues are derived from recurring revenues and services revenues.

Total revenues increased 26.7%20.5% to $224.7 million for the three months ended June 30, 2017 from $186.5 million for the three months ended June 30, 2016 from $147.2and 21.3% to $453.2 million for the threesix months ended June 30, 2015, and 28.0% to2017 from $373.8 million for the six months ended June 30, 2016 from $292.1 million for the six months ended June 30, 2015.2016.
Recurring revenues, consisting of subscription revenues from cloud-based UltiPro, increased 27.4%23.1% to $195.1 million for the three months ended June 30, 2017, from $158.5 million for the three months ended June 30, 2016 from $124.4and 23.7% to $385.1 million for the threesix months ended June 30, 2015 and 27.8% to2017, from $311.2 million for the six months ended June 30, 2016 from $243.5 million for the six months ended June 30, 215.2016. The increases for the three and six months ended June 30, 20162017 in cloud revenues were primarily based on the revenue impact of incremental units sold to customers that have processed their first payroll using UltiPro (or gone "Live") since June 30, 2015,2016, including the UltiPro core product and, to a lesser extent, Optional Capabilities of UltiPro. Cloud subscription revenues are recognized as recurring revenues over the initial contract period, as those services are delivered, typically commencing with the Live date.

Our annual revenue customer retention rate for our recurring revenue cloud customer base exceeded 97%was approximately 96% as of June 30, 20162017 (calculated on a 12-month rolling basis), which compares with greater than 96%over 97% for the samecomparable period inof the prior year. The impact on recurring revenues of UltiPro units sold has been a gradual increase from one reporting period to the next, based on the incremental effect of revenue recognition of the subscription fees over the terms of the related contracts as sales in backlog go Live.
Services revenues increased 22.9%5.3% to $29.5 million for the three months ended June 30, 2017 from $28.1 million for the three months ended June 30, 2016 from $22.8and 8.9% to $68.1 million for the threesix months ended June 30, 2015 and 28.7% to2017 from $62.5 million for the six months ended June 30, 2016 from $48.6 million for the six months ended June 30, 2015.2016. The increases in services revenues for the three- and six-month periods were primarily due to additional implementation revenues from incremental billable consultants to support increased sales, and,partially offset primarily by lower revenues from time clocks as sales of time clocks are shifting to more sold on a lesser extent,per device per month (or subscription) basis.
As a result of an increase in the print services that we offer our customers (which occurrednumber of enterprise sales being made to larger and more complex companies, the time-to-live periods (i.e., the period of time from the contract sale date through the Live date) in the first quarterenterprise backlog have expanded by an average of 2016).2-3 months. We also experienced the same business effect with our mid-market sales for which the related backlog expanded by an average of 1-2 months. We anticipate these time-to-live extensions will cause our recurring revenues and services revenues to be lower than originally estimated at the beginning of 2017. It is important to note that the extension of the time-to-live periods does not change the overall value of recurring revenues or our fixed fee implementation revenues (included with services revenues) from these customers and is essentially a timing issue.
Cost of Revenues
Cost of revenues consists of the costs of recurring and services revenues. Cost of recurring revenues primarily consists of costs to provide customer support services ("Customer Support") to cloud customers, the cost of providing periodic updates and the cost of recurring subscription revenues, including hosting data center costs and, to a lesser extent, amortization of capitalized software. Cost of services revenues primarily consists of costs to provide implementation services and training to Ultimate’s customers and, to a lesser extent, costs related to sales of payroll-related forms, time clocks and print services, as well as costs associated with certain client reimbursable out-of-pocket expenses.
Total cost of revenues increased 24.6%16.5% to $84.3 million for the three months ended June 30, 2017, from $72.3 million for the three months ended June 30, 2016 from $58.0and 20.3% to $174.0 million for the threesix months ended June 30, 2015 and 25.6% to2017, from $144.6 million for the six months ended June 30, 2016 from $115.1 million for the six months ended June 30, 2015.2016.
Cost of recurring revenues increased 24.9%22.3% to $52.5 million for the three months ended June 30, 2017 from $43.0 million for the three months ended June 30, 2016 from $34.4and 24.5% to $102.6 million for the threesix months ended June 30, 2015 and 22.7% to2017 from $82.4 million for the six months ended June 30, 2016 from $67.2 million for the six months ended June 30, 2015.2016. The increases in the cost of recurring revenues for the three- and six-month periods were primarily due to increases in both cloud costs and Customer Support costs, as described below:below, and, to a lesser extent, increased amortization of capitalized software costs from the development costs related to a development project to be sold in the future as a cloud product only (the "Development Project") which resulted from another product module becoming available for its intended use during December 2016:
For the three and six months ended June 30, 2016,2017, the increasesincrease in cloud costs were principally as a result of the growth in cloud operations from increased sales, including increased labor costs and, to a lesser extent, increased variable costs associated with our cloud operations.
The increases in Customer Support costs for the three and six months ended June 30, 20162017 were primarily due to higher labor costs commensurate with the growth in the number of cloud customers serviced.

Cost of services revenues increased 24.2%8.1% to $31.7 million for the three months ended June 30, 2017 from $29.3 million for the three months ended June 30, 2016 from $23.6and 14.8% to $71.3 million for the threesix months ended June 30, 2015 and 29.6% to2017 from $62.1 million for the six months ended June 30, 2016 from $47.9 million for the six months ended June 30, 2015.2016. The increases in cost of services revenues for the three- and six-month periods were primarily due to the increased cost of implementation, including higher labor and related costs (particularly in association with the increased number of billable consultants) and, to a lesser extent, the increased use of third parties, includingparty implementation partners.partners, partially offset by lower costs associated with the timing of one of our national meetings for the services organization which was held in the quarter ended June 30, 2016 but, in 2017, is being held in the third fiscal quarter.
Sales and Marketing
Sales and marketing expenses consist primarily of salaries and benefits, sales commissions, travel and promotional expenses, and facility and communication costs for direct sales offices, as well as advertising and marketing costs. Sales and marketing expenses increased 39.2%22.9% to $67.0 million for the three months ended June 30, 2017 from $54.5 million for the three months ended June 30, 2016 from $39.2and 22.7% to $136.4 million for the threesix months ended June 30, 2015 and 39.0% to2017 from $111.1 million for the six months ended June 30, 2016 from $80.0 million for the six months ended June 30, 2015.2016. The increases in sales and marketing expenses for the three- and six-month periods were primarily due to increased labor and related costs (including sales commissions and the impact of an increase in sales personnel) and, to a lesser extent, higher advertising and marketing expenses. Included in the increased labor and related costs for the three and six months ended June 30, 20162017 was a portion of certain non-cash, stock-based compensation expenses relating to one-time grants of restricted stock awards given to certain senior officers whose rights to receive cash payments upon a change in control of Ultimate were either terminated or significantly reduced.terminated. Under the terms of the applicable change in control plans, we were required to provide each such senior officer with “comparable value” with respect to the reduction or termination of his or her change in control award. Commissions on cloud sales are amortized over the initial contract term (typically 24 to 36 months) typically commencing on the Live date, which corresponds with the related cloud revenue recognition.

Research and Development
Research and development expenses consist primarily of software development personnel costs. Research and development expenses increased 21.5%20.5% to $35.0 million for the three months ended June 30, 2017 from $29.1 million for the three months ended June 30, 2016 from $23.9and 25.8% to $71.1 million for the threesix months ended June 30, 2015 and 24.9% to2017 from $56.6 million for the six months ended June 30, 2016 from $45.3 million for the six months ended June 30, 2015.2016. The increases in research and development expenses for the three- and six-month periods were principally due to higher labor and related costs associated with the ongoing development of UltiPro and Optional Capabilities, including the impact of increased personnel costs (predominantly from additional headcount), net of capitalized labor costs. During the three months ended June 30, 20162017 and June 30, 2015,2016, we capitalized a total of $9.0$13.6 million (including $1.0 million in non-cash stock-based compensation) and $6.3$9.0 million (including $0.6$1.0 million in non-cash stock-based compensation), respectively, for internal-use software costs from a development project that will be offered as a cloud product (the "Development Project"). During the six months ended June 30, 2017 and June 30, 2016, we capitalized a total of $26.2 million (including $2.0 million in non-cash stock-based compensation) and $17.0 million (including $2.0 million in non-cash stock-based compensation), respectively, for the Development Project. The capitalized costs for this Development Project were from direct labor costs and, to a lesser extent, third party consulting fees for the three months ended June 30, 2016. During theand six months ended June 30, 2016 and June 30, 2015, we capitalized a total of $17.0 million (including $2.0 million in non-cash stock-based compensation) and $12.8 million (including $1.4 million in non-cash stock-based compensation), respectively, for the Development Project.2017. During the three and six months ended June 30, 2016,2017, there was $0.3were $1.0 million and $0.5$2.0 million respectively, in each of the respective periods of amortization associated with a particularcertain product module, Recruitment,modules of the Development Project which waswere ready for itstheir intended use during the second quarter of 2014.use. The amortization of capitalized software is included in cost of recurring revenues.
General and Administrative
General and administrative expenses consist primarily of salaries and benefits of executive, administrative and financial personnel, as well as facility costs, external professional fees and the provision for doubtful accounts. General and administrative expenses increased 20.0%41.9% to $31.5 million for the three months ended June 30, 2017 from $22.2 million for the three months ended June 30, 2016 from $18.5and 41.1% to $61.7 million for the threesix months ended June 30, 2015 and 27.3% to2017 from $43.7 million for the six months ended June 30, 2016 from $34.3 million for the six months ended June 30, 2015.2016. The increases in general and administrative expenses for the three- and six-month periods were primarily due to higher labor and related costs, including increased personnel to support Ultimate's growth in operations, an increase in facility costs to support the growth in headcount, including our Weston, Florida headquarter locations, increased professional fees, an increase in the provision for doubtful accounts, and a portion of certain non-cash, stock-based compensation expenses relating to one-time grants of restricted stock awards given to certain senior officers whose rights to receive cash payments upon a change in control of Ultimate were either terminated or significantly reduced.terminated. Under the terms of the applicable change in control plans, we were required to provide each such senior officer with “comparable value” with respect to the reduction or termination of his or her change in control award.

Income Taxes
Income taxes for the three months ended June 30, 2017, included a consolidated tax provision of $1.9 million. Income taxes for the six months ended June 30, 2017, included a consolidated tax benefit of $2.5 million. The effective income tax rate for the three and six months ended June 30, 2017 was 27.2% and (24.8)%, respectively. Income taxes for the three and six months ended June 30, 2016 (as restated for the effect of ASU 2016-09) included a consolidated provision of $6.7$2.3 million and $13.5$4.9 million, respectively. The effective income tax rate for the three and six months ended June 30, 2016 was 80.0%27.0% and 76.7%, respectively. Income taxes for the three and six months ended June 30, 2015 included a consolidated provision of $3.9 million and $9.4 million, respectively. The effective income tax rate for the three and six months ended June 30, 2015 was 51.5% and 54.7%27.8%, respectively. The increaseschange in the effective income tax rate for the three and six months ended June 30, 2016,2017, as compared with the three and six months ended June 30, 2015, were2016, was primarily due to an increase in the recognition of excess tax benefits in the three and six months ended June 30, 2017 as compared to June 30, 2016 resulting from the adoption of ASU 2016-09. This was partially offset by an increase in non-deductible expenses, primarily stock based compensation, and a resulting higher ratio of non-deductible expenses to pre-tax income.
At December 31, 2015,2016, we had approximately $150.7$148.5 million of net operating loss carryforwards for Federal income tax reporting purposes available to offset future taxable income. Approximately $149.7 million wasPrior to January 1, 2016, the tax benefit of net operating loss carryforwards attributable to deductions from the exercise of non-qualified employee, and non-employee director, stock options and the vesting of restricted stock units and restricted stock awards, the tax benefit of which will primarily bewere credited to paid-in-capital and deferred tax asset when realized.only to the extent realized through a reduction of income taxes payable. As a result, prior to January 1, 2016, the excess tax benefits associated with stock basedstock-based compensation arewere included in net operating loss carryforwards but not reflected in deferred tax assets. Upon adoption of ASU 2016-09, the excess tax benefits associated with stock based compensation were reflected in deferred tax assets. These excess tax benefits combined with the associated financial statement expense (previously included in the stock-based compensation line of the annual tax footnote included in Ultimate’s Form 10-K), are currently reflected in the net operating loss line of the deferred tax schedule in Ultimate's Form 10-K.
During 2016, we realized a tax benefit of $49.0 million comprised of a $23.8 million and a $25.2 million credit to income tax expense and deferred tax asset, respectively. The carryforwards expire from 2018 through 2035 and from 2016 through 2035, for Federal and state income tax reporting purposes, respectively. Utilization of such net operating loss carryforwards may be limited as a result of cumulative ownership changes in Ultimate’s equity instruments due to ownership change provisions of Internal Revenue Code Section 382 and similar state law provisions.
As of December 31, 2015,2016, we had $6.0$7.2 million of gross unrecognized tax benefits resulting from a research and development credit attributable to the years 1998 through 2015, as a result of research and development credit activities studies,2016, that if recognized would affect the annual effective tax rate. While it is often difficult to predict the final outcome of any particular uncertain tax position, management does not believe that it is reasonably possible that the estimates of unrecognized tax benefits will change significantly in the next twelve months.

We recognized $48.9$70.3 million of deferred tax assets, net of deferred tax liabilities, as of June 30, 2016.2017. If estimates of taxable income are decreased, a valuation allowance may need to be provided for some or all deferred tax assets, which will cause an increase in income tax expense. Management continues to apply the exception to the comprehensive recognition of deferred income taxes to the undistributed earnings of our foreign subsidiary, The Ultimate Software Group of Canada, Inc. (“Ultimate Canada”). Accordingly, deferred income taxes were not recognized on the cumulative undistributed earnings of Ultimate Canada. The deferred tax liability, net of available foreign tax credits, resulting from such cumulative undistributed earnings were not deemed material.
Liquidity and Capital Resources
In recent years, we have funded operations primarily from cash flows generated from operations.
As of June 30, 2016,2017, we had $98.0$111.0 million in cash, cash equivalents and short-term corporate investments in marketable securities (collectively, "Cash"), reflecting a net decreaseincrease of $22.1$21.6 million since December 31, 2015.2016.  The total decreaseincrease in Cash for the six-month period was primarily from cash used forprovided by operations of $89.5 million and proceeds from the repurchases of sharesissuances of Common Stock under our previously announcedfrom employee and non-employee director stock repurchase plan ("Stock Repurchase Plan"),option exercises of $29.7$4.5 million, $18.6partially offset by cash purchases of property and equipment (including principal payments on financed equipment) of $46.7 million (which includes $24.2 million of capitalized labor costs and third party consulting fees, paid in cash, associated with the Development Project) and cash used to settle the employee tax withholding liability for vesting of restricted stock awards and restricted stock units cash purchases of property and equipment (including principal payments on financed equipment) of $33.6 million (which includes $15.1 million of capitalized labor costs, paid in cash, associated with the Development Project) and $9.1 million of cash used for the Vestrics Acquisition, partially offset by cash provided by operations of $65.6 million (excluding the non-cash impact of the excess tax benefit associated with stock-based payment deductions) and proceeds from the issuances of Common Stock from employee and non-employee director stock option exercises of $2.7$34.7 million.
Our operating cash inflows primarily consist of payments received from our UltiPro customers. Our operating cash outflows primarily consist of cash we invest in personnel and infrastructure to support the anticipated growth of our business, payments to vendors directly related to our services, payments under arrangements with third party vendors who provide hosting infrastructure services in connection with UltiPro, related sales and marketing costs, costs of operations and systems development and programming costs. Net cash provided by operating activities increased $8.9$23.9 million during the six months

ended June 30, 20162017 to $52.5$89.5 million, as compared with $43.6$65.6 million for the six months ended June 30, 2015.2016. This increase was primarily due to an increase in cash operating income (after adjusting for non-cash expenses) of $19.9$15.3 million and increased cash from working capital, partially offset by increased cash paid for working capital, including prepaid commissions (short- and long-term) in association with increased sales.sales made during the six-month period.
The net cash outflow fromused in investing activities was $57.4 million for the six months ended June 30, 2017, as compared with a net cash outflow of $52.8 million for the six months ended June 30, 2016, as compared with a net cash inflow2016.  The increase of $337.0 million for the six months ended June 30, 2015.  The decrease of $389.8$4.6 million was primarily attributable to a net decreasechange in client funds received from our customers using the UltiPro payment services offering (“UltiPro Payment Services”) of $285.8$36.3 million, and an increase in cash purchases of property and equipment of $9.9 million, partially offset by an increase in the maturities of marketable securities of $16.9 million (which includes the maturities for the period of $59.1 million of marketable securities originally purchased with funds held for customers in addition to our corporate funds), and a decrease in the purchases of marketable securities of $134.3$15.5 million (which includes $123.0purchases for the period of $119.8 million of funds held for customers being invested in marketable securities in addition to our corporate funds), an increase in cash purchases of property and equipment of $12.3 million and cash used for the Vestrics Acquisition totaling $9.1 million, partially offset by an increase in maturities of marketable securities of $51.8 million. As part of the terms of the Vestrics Acquisition, there is $1.0 million of cash held in escrow.. During the six months ended June 30, 2016,2017, we capitalized software development costs related to the Development Project totaling $17.0$26.2 million (including $2.0 million from the non-cash impact of capitalized stock-based compensation expense), which was classified as property and equipment. Beginning in December 2015, we began investingWe invest our customer funds in available for sale securities along with our corporate funds in accordance with our internal investment strategies. The portfolio predominantly consists of investment grade securities with long-term ratings of AAA and AA+ and short-term ratings A-1/P-1. Customer funds not invested in available for sale securities, temporarily held by us as a result of our UltiPro Payment Services, are invested in U.S. Government money market funds that invest in short-term, high quality money market instruments which consist of U.S. Treasury and U.S. Government Agency obligations and repurchase agreements collateralized by such obligations. The money market funds are rated AAA by Standard & Poor's and Aaa by Moody's. Any residual customer funds are held primarily in our bank accounts.
Net cash used in financing activities was $27.5$8.1 million for the six months ended June 30, 2016,2017, as compared with $383.9$40.6 million net cash used in financing activities for the six months ended June 30, 2015.2016. The $356.3$32.5 million decrease in cash used in financing activities was primarily related to a net increase of $365.7 million in client fund obligations for our UltiPro Payment Services and a decrease of $1.1$29.7 million in cash used for the repurchases of shares of our Common Stock under our Stock Repurchase Plan, a net change of $17.4 million in customer funds obligations for our UltiPro Payment Services, an increase in the net proceeds from issuances of Common Stock of $1.8 million and a decrease in cash used for the repayments of other borrowings of $0.2 million, partially offset by a decrease of $2.8 million in the excess tax benefits associated with stock-based payment deductions, and an increase of $7.8$16.2 million in cash used to settle employee tax withholding liabilities upon the vesting of their restricted stock awards and restricted stock unit awards.

awards and an increase of $0.3 million in cash used for principal payments on capital lease obligations.
Days sales outstanding (or "DSOs"), calculated on a trailing three-month basis, as of June 30, 20162017 were 7268 days as compared with 6772 days as of June 30, 2015.2016. The increasedecrease of fivefour days was associated with increased revenues and stronger sales bookingscollections during the second quarter of 2016.2017.
Deferred revenues were $159.0$187.0 million at June 30, 2016,2017, as compared with $145.7$174.0 million at December 31, 2015.2016. The increase of $13.3$13.0 million in deferred revenues was primarily due to increasedincremental sales.
We believe that cash and cash equivalents, investments in marketable securities, equipment financing, other borrowings and cash generated from operations will be sufficient to fund our operations for at least the next 12 months. This belief is based upon, among other factors, management’s expectations for future revenue growth, controlled expenses and collections of accounts receivable.
As of June 30, 2016,2017, we did not have any material commitments for capital expenditures, except for anticipated capitalized costs associated with the Development Project.
Off-Balance Sheet Arrangements
We do not, and, as of June 30, 2016,2017, we did not, have any off-balance sheet arrangements (as that term is defined in applicable SEC rules) that are reasonably likely to have a current or future material effect on our financial condition, results of operations, liquidity, capital expenditures or capital resources.
Quarterly Fluctuations
Our quarterly revenues and operating results have varied significantly in the past and are likely to vary substantially from quarter to quarter in the future. Our operating results may fluctuate as a result of a number of factors, including, but not limited to, increased expenses (especially as they relate to product development, sales and marketing and the use of third-party consultants), timing of product releases, increased competition, variations in the mix of revenues, announcements of new products by us or our competitors and capital spending patterns of our customers. We establish our expenditure levels based upon our expectations as to future revenues, and, if revenue levels are below expectations, expenses can be disproportionately

high. A drop in near term demand for our products could significantly affect both revenues and profits in any quarter. Operating results achieved in previous fiscal quarters are not necessarily indicative of operating results for the full fiscal year or for any future periods. As a result of these factors, there can be no assurance that we will be able to maintain profitability on a quarterly basis. We believe that, due to the underlying factors for quarterly fluctuations, quarter-to-quarter comparisons of Ultimate’s operations are not necessarily meaningful and that such comparisons should not be relied upon as indications of future performance.
Forward-Looking Statements
The foregoing Management’s Discussion and Analysis of Financial Condition and Results of Operations and the following Quantitative and Qualitative Disclosures about Market Risk contain certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements represent our expectations or beliefs, including, but not limited to, our expectations concerning our operations and financial performance and condition. Words such as “anticipates,” “expects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements are not guarantees of future performance and are subject to certain risks and uncertainties that are difficult to predict. Ultimate’s actual results could differ materially from those contained in the forward-looking statements due to risks and uncertainties associated with fluctuations in our quarterly operating results, concentration of our product offerings, development risks involved with new products and technologies, competition, our contractual relationships with third parties, contract renewals with business partners, compliance by our customers with the terms of their contracts with us, and other factors disclosed in Ultimate’s filings with the SEC. Other factors that may cause such differences include, but are not limited to, those discussed in this Form 10-Q and the Form 10-K, including the risk factors set forth in "Part I, Item 1A. Risk Factors" of the Form 10-K. Ultimate undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
Non-GAAP Financial Measures
Item 10 (e) of Regulation S-K, "Use of Non-GAAP Financial Measures in Commission Filings," defines and prescribes the use of non-GAAP financial information. Our measure of Non-GAAP Operating Income, which excludes non-cash stock-based compensation and amortization of acquired intangibles, meets the definition of a non-GAAP financial measure.

Ultimate believes that this non-GAAP measure of financial results provides useful information to management and investors regarding certain financial and business trends relating to Ultimate's financial condition and results of operations. Ultimate's management uses this non-GAAP result to compare Ultimate's performance to that of prior periods for trend analyses, for purposes of determining executive incentive compensation, and for budget and planning purposes. This measure is used in monthly financial reports prepared for management and in quarterly financial reports presented to Ultimate's Board of Directors. This measure may be different from non-GAAP financial measures used by other companies.
This non-GAAP measure should not be considered in isolation or as an alternative to such measures determined in accordance with GAAP. The principal limitation of this non-GAAP financial measure is that it excludes significant expenses that are required by GAAP to be recorded. In addition, it is subject to inherent limitations as it reflects the exercise of judgment by management about which expenses are excluded from the non-GAAP financial measure.
To compensate for these limitations, Ultimate presents its non-GAAP financial measure in connection with its GAAP result. Ultimate strongly urges investors and potential investors in Ultimate's securities to review the reconciliation of its non-GAAP financial measure to the comparable GAAP financial measure that is included in the table below and not to rely on any single financial measure to evaluate its business.
We exclude the following items from the non-GAAP financial measure, Non-GAAP Operating Income (and the related non-GAAP operating income, as a percentage of total revenue (or non-GAAP operating margin)), as appropriate:
Stock-based compensation expense. Ultimate's non-GAAP financial measure excludes stock-based compensation expense, which consists of expenses for stock options and stock and stock unit awards recorded in accordance with ASC 718, “Compensation - Stock Compensation.” For the three and six months ended June 30, 2016,2017, stock-based compensation expense was $28.6$39.3 million and $55.1$73.1 million, respectively, on a pre-tax basis. For the three and six months ended June 30, 2015,2016, stock-based compensation expense was $21.8$28.6 million and $37.9$55.1 million, respectively, on a pre-tax basis. Stock-based compensation expense is excluded from the non-GAAP financial measures because it is a non-cash expense that Ultimate does not consider part of ongoing operations when assessing its financial performance. Ultimate believes that such exclusion facilitates the comparison of results of ongoing operations for current and future periods with such results from past periods. For GAAP net income periods, non-GAAP reconciliations are calculated on a diluted weighted average share basis.

Amortization of acquired intangible assets. In accordance with GAAP, operating expenses include amortization of acquired intangible assets over the estimated useful lives of such assets. For the three and six months ended June 30, 20162017, the amortization of acquired intangible assets was $0.8 million and 2015,$1.6 million, respectively. For the three and six months ended June 30, 2016, the amortization of acquired intangible assets was $0.3 million and $0.5 million, respectively. Amortization of acquired intangible assets is excluded from Ultimate’s non-GAAP financial measures because it is a non-cash expense that Ultimate does not consider part of ongoing operations when assessing its financial performance. Ultimate believes that such exclusion facilitates comparisons to its historical operating results and to the results of other companies in the same industry, which have their own unique acquisition histories.
The following table reconciles GAAP operating income with non-GAAP operating income (in thousands):

ITEM 3.Quantitative and Qualitative Disclosures About Market Risk
In the ordinary course of Ultimate’s operations, we are exposed to certain market risks, primarily interest rate risk and foreign currency risk. Risks that are either non-financial or non-quantifiable, such as political, economic, tax, or regulatory risks, are not included in the following assessment of our market risks.
Interest Rate Risk. Ultimate is subject to financial market risks, including changes in interest rates which influence the valuations of our fixed income investment portfolio. Changes in interest rates could also impact Ultimate’s anticipated interest income from interest-bearing cash accounts, or cash equivalents and investments in marketable securities. We manage financial market risks, including interest rate risks, in accordance with our investment guideline objectives, including:
Maximum safety of principal;
Maintenance of appropriate liquidity for regular cash needs;
Maximum yields in relationship to guidelines and market conditions;
Diversification of risks; and
Fiduciary control of all investments.
Ultimate targets its fixed income investment portfolio to have maturities of 24 months or less. Investments are held to enhance the preservation of capital and not for trading purposes.
Cash equivalents consist of money market accounts with original maturities of less than three months. Short-term investments include obligations of U.S. government agencies, asset-backed securities and corporate debt securities. Corporate debt securities include commercial paper which, according to Ultimate’s investment guidelines, must carry minimum short-term ratings of P-1 by Moody’s Investor Service, Inc. (“Moody’s”) and A-1 by Standard & Poor’s Ratings Service, a Division of The McGraw-Hill Companies, Inc. (“S&P”). Other corporate debt obligations must carry a minimum rating of A-2 by Moody’s or A by S&P. Asset-backed securities must carry a minimum AAA rating by Moody’s and S&P with a maximum average life of two years at the time of purchase.
As of June 30, 2016,2017, total corporate investments in available-for-sale marketable securities were $22.6$12.9 million. As of June 30, 2017, total investments with customer funds in available-for-sale marketable securities were $208.9 million.
As of June 30, 2016,2017, virtually all of the investments in Ultimate’s corporate portfolio, and portfolio of investments with customer funds, were at fixed rates (with a weighted average interest rate of 0.8%1.3% and 1.2% per annum)annum, respectively).
To illustrate the potential impact of changes in interest rates, Ultimate has performed an analysis based on its June 30, 20162017 unaudited condensed consolidated balance sheet and assuming no changes in its investments.  Under this analysis, an immediate and sustained 100 basis point increase in the various base rates would result in a decrease in the fair value of Ultimate’s totalcorporate portfolio of approximately $182$81 thousand over the next 12 months and a decrease in the fair value of Ultimate's portfolio of investments with customer funds of approximately $1.6 million over the next 12 months. An immediate and sustained 100 basis point decrease in the various base rates would result in an increase in the fair value of Ultimate’s totalcorporate portfolio of approximately $143$81 thousand over the next 12 months and an increase in the fair value of Ultimate's portfolio of investments with customer funds of approximately $1.6 million over the next 12 months.
Foreign Currency Risk. Ultimate has foreign currency risks related to its revenue and operating expenses denominated in currencies other than the U.S. dollar. Management does not believe movements in the foreign currencies in which Ultimate transacts business will significantly affect future net income.

ITEM 4.Controls and Procedures
(a) Evaluation of disclosure controls and procedures. Ultimate carried out an evaluation, under the supervision and with the participation of Ultimate’s management, including the Chief Executive Officer (the “CEO”) and the Chief Financial Officer (the “CFO”), of the effectiveness of the design and operation of Ultimate’s disclosure controls and procedures as of the end of the period covered by this Form 10-Q pursuant to Rule 13a-15(b) under the Exchange Act. Based on that evaluation, Ultimate’s management, including the CEO and CFO, concluded that, as of June 30, 2016,2017, Ultimate’s disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in Ultimate’s Exchange Act reports is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms and is accumulated and communicated to management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure. Ultimate’s disclosure controls and procedures were designed to provide reasonable assurance as to the achievement of these objectives. It should be noted that the design of any system of controls is based in part upon certain assumptions about the likelihood of future events and thus has inherent limitations. Therefore, even those systems determined to be effective can only provide reasonable assurance as to the achievement of their objectives.
(b) Changes in internal control over financial reporting. There have been no changes during the quarter ended June 30, 20162017 in Ultimate’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, Ultimate’s internal control over financial reporting.
