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

1.Nature of Operations
The Ultimate Software Group, Inc. and subsidiaries (“Ultimate,” “we,” “us” or “our”) is a leading cloud provider of peoplecloud-based human capital management solutions, often referred to as human capital management (“HCM”). 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 twelve14 languages with more than 3537 country-specific localizations. The solution is delivered via software-as-a-service ("SaaS"), now more commonly known as the cloud computing model, 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 enterprise companies, which we define as organizations with 2,501 or more employees, including those with 10,000 or more employees; mid-market companies, which we define as those having 501-2,500 employees; and strategic market companies, which we define as those having 100-500 employees. UltiPro is marketed primarily through our 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, 20162017 filed with the SEC on February 24, 201726, 2018 (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 nine months ended September 30, 2017March 31, 2018 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 ofAccounting Standards and 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, 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, accounts receivable, accounts payable, capital lease obligations and other long-term liabilities, approximated fair value (due to their relatively short maturity) as of September 30, 2017 and December 31, 2016. Marketable securities included in funds held for customers and the related obligations consist primarily of securities classified as available-for-sale and are recorded at fair value on a recurring basis.

Recently IssuedAdopted Accounting Standards
In May 2014, the FASB issued ASUAccounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("(Topic 606)” (“Topic 606)”606”).Topic 606 supersedes the revenue requirements in ASU Topic 605, Revenue Recognition ("Topic 605") and requires the recognition of revenues 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 ifof 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 revenuerevenues and cash flows arising from contracts with customers. Collectively, 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 withinstandard."

Effective January 1, 2018, we adopted the revenue recognition process than are required under existing GAAP, including identifying performance obligations in the contract, estimating the amountrequirements of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation, among others.
We began assessing the new standard, in 2016 and have continued our assessment during 2017 to addressutilizing the potential impact that Topic 606 could have on our consolidated financial statements and the required resources to implement the new standard. Our assessmentmodified retrospective method of the impact included an evaluation of the five step process along with the enhancement of 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 effectivelytransition with the new standard and performing gap analysesapplied to all customer contracts that were not completed on collected data and determining the relative accounting positions where applicable. Included in our assessmenteffective date of the new standard. Adoption of the new standard we are focusedresulted in changes to our accounting policies for revenue recognition, as detailed below.

The impact of adopting the new standard on the potential impact on sales commissionsour revenues resulted in an immaterial increase to deferred revenue and the term over which they will amortize.
We anticipate this standard will not havehad a material impact on our unaudited condensed consolidated balance sheet, as a result of the way we recognize revenues. The new standard will require us to defer incremental commissionamortization period over which deferred contract costs to obtain related subscription contracts over the period of benefit. Whileare recognized. Under Topic 605, 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 anddeferred incremental commission costs to obtain a contract and amortizeamortized those costs over the initial term of the related subscription contract, which

is generally 2-3 years. We are still evaluating the overall effectDuring our assessment of the new standard, willwe did not identify any incremental contract costs from what was capitalized under Topic 605. We analyzed our customer contract term periods and our customer life, taking into consideration technological changes for our UltiPro product offering, and based on our assessment of the new standard, we amortize the deferred contract costs over 7 years on a systematic basis, consistent with the pattern of transfer of the goods or services to which the asset relates.

The cumulative effect of the changes made to our January 1, 2018 balance sheet for the adoption of the new standard were as follows (in thousands):

Summary of Significant Accounting Policies
Except for the accounting policy for revenue recognition that was updated as a result of adopting Topic 606, there have been no changes to our significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on February 26, 2018, that have had a material impact on our unaudited condensed consolidated financial statements and related disclosures.notes.
Revenue Recognition
Effective January 1, 2018, we recognize revenues in accordance with Topic 606. The core principle of Topic 606 is effectivethat revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for Ultimatethose products or services. To achieve the core principle of Topic 606, we perform the following steps:
1)    Identify the contract(s) with a customer;
2)    Identify the performance obligations in the contract;
3)    Determine the transaction price;
4)    Allocate the transaction price to the performance obligations in the contract; and
5)    Recognize revenue when (or as) we satisfy a performance obligation.

The significant majority of our two major revenue sources - recurring and services is derived from contracts with customers. Recurring revenues are primarily related to our subscription-based SaaS performance obligations. Services revenues are primarily related to implementation services for our SaaS customers (including activation services as well as post-live work typically billed on January 1, 2018 using eithera time and materials basis) and, to a much lesser extent, fees for other services, including the provision of two transition methods including several practical expedients: (1) full retrospective method,payroll-related forms, sales of time clocks and the printing of W-2 and Affordable Care Act ("ACA") forms for certain customers, as well as certain client reimbursable out-of-pocket expenses. Fees charged to subscription-based SaaS performance obligations are each priced on a per-employee-per-month (“PEPM”) basis for a given calendar month based on usage and fees

charged for implementation services and are typically priced on a fixed fee basis for activating the product offering. A majority of our SaaS subscription revenues are satisfied over time, because they are simultaneously received and consumed by the customer, with certain SaaS performance obligations satisfied at a point in whichtime. Our activation services revenues are satisfied over time because they are simultaneously received and consumed by the new standard would be applied tocustomer.

Our SaaS performance obligations are each prior reporting period presented or (2)priced based on the modified retrospective method, in whichnumber of active customer employees, as of the cumulative effectsigning of initially applying the new standard would be recognizedcontract, at the contract PEPM rate over the initial contract term. Our activation services are based on a fixed fee charged to our customers. There is typically no variable consideration related to our SaaS performance obligations or our activation services, nor do they include a significant financing component, non-cash consideration, or consideration payable to a customer. Our SaaS performance obligations are typically billed quarterly in advance while our activation services are billed over the implementation period.
Our SaaS arrangements include multiple performance obligations and transaction price allocations are based on the stand-alone selling price ("SSP") for each performance obligation. There is an observable input for SSP for each of the SaaS performance obligations. Since activation services do not have directly observable pricing, the SSP is estimated using market conditions and observable inputs, which is calculated based on historical average discounts off our standard price list.
For our performance obligations, the consideration allocated to cloud subscription revenues is recognized as recurring revenues, typically using the output method, over the initial contract period, as those subscription-based services are consumed, typically commencing with the date of initial application and providing certain additional disclosuresthe customer processes their first live payroll using UltiPro (referred to as defined pergoing "Live"). The consideration allocated to activation services is recognized as services revenues based on the new standard. Ultimate has not yet selected a transition method.proportion performed, using reasonably dependable estimates (in relation to progression through activation phases), by product.
Recently Issued Accounting Standards
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 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 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. Effective January 1, 2017 the Company adopted ASU 2015-17. Subsequent to adoption, all deferred tax assets and deferred tax liabilities are presented as non-current on the consolidated balance sheet. The changes have been applied prospectively as permitted by the ASU and prior years have not been restated. The adoption of this ASU does not have a material effect on the Company's results of operations, financial condition or liquidity.
4.    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 lossincome 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 nine months ended September 30, 2017March 31, 2018 and September 30, 2016.March 31, 2017.
Gains and losses on the sale of available-for-sale securities are determined using the specific identification method.   There was $406$982 thousand and $145$704 thousand of net unrealized loss on available-for-sale securities as of September 30, 2017March 31, 2018 and December 31, 2016,2017, respectively.
The amortized cost, net unrealized loss and fair value of our funds held for customers and corporate investments in marketable available-for-sale securities as of September 30, 2017March 31, 2018 and December 31, 20162017 are shown below (in thousands):

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. We have had assets in the 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 September 30, 2017March 31, 2018 or as of December 31, 2016.2017. We did not have any transfers into and out of Level 1 or Level 2 during the three and nine months ended September 30, 2017March 31, 2018 or the twelve months ended December 31, 2016.2017. No assets or investments were classified as Level 3 as of September 30, 2017March 31, 2018 or as of December 31, 2016.

2017.
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 September 30, 2017March 31, 2018 and December 31, 20162017 (in thousands):

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 September 30, 2017March 31, 2018 and December 31, 20162017 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 nine months ended September 30, 2017,March 31, 2018, we capitalized $13.9$14.6 million and $40.1 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 $9.2 million and $26.2was $12.6 million of software development costs related to the Development Project which were capitalized in the three and nine months ended September 30, 2016, respectively.March 31, 2017. For the three and nine months ended September 30,March 31, 2018 and March 31, 2017, and September 30, 2016, these capitalized costs were primarily direct labor costs. As a component of these direct labor costs we capitalized $1.0 million and $3.0 million of stock-based compensation costs during the three and nine months ended September 30, 2017, respectively.March 31, 2018. During the three and nine months ended September 30, 2016,March 31, 2017, we capitalized $1.0 million and $2.8 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 sheetsheets 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 nine months ended September 30, 2017March 31, 2018 there were $1.0was $1.8 million and $3.1 million, respectively, of amortization associated with certain product modules of the Development Project which were ready for their intended use. During the three and nine months ended September 30, 2016March 31, 2017 there were $0.3was $1.0 million and $0.8 million, respectively, of amortization associated with certain product modules of the Development Project which were ready for their intended use. The amortization of capitalized software is included in cost of recurring revenues.

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, 20162017 were as follows (in thousands):
Goodwill, December 31, 2016$35,322
Translation adjustment for the nine months ended September 30, 2017 (1)537

(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 September 30, 2017March 31, 2018 and December 31, 2016,2017 were $0.1 million of assets with indefinite lives. Amortization expense for acquired intangible assets was $0.8 million and $2.3 million for the three and nine months ended September 30, 2017, respectively,March 31, 2018 and $0.3 million and $0.8 million for the three and nine months ended September 30, 2016, respectively.March 31, 2017.
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 nine months ended September 30,March 31, 2018 and 2017 and 2016 (in thousands):

11.     Deferred Revenue and Performance Obligations
During the three months ended March 31, 2018 and 2017, $144.1 million and $119.9 million, respectively, of recurring revenues recognized, were included in the deferred revenue balances at the beginning of the respective periods. Services revenues recognized in the same periods from deferred revenue balances at the beginning of the respective periods were not material.
Transaction Price Allocated to the Remaining Performance Obligations
As of March 31, 2018, approximately $1.6 billion of revenue is expected to be recognized from remaining SaaS performance obligations which includes the remaining period of their initial contract term as well as the remaining renewal periods under contract as of March 31, 2018. We expect to recognize revenue on approximately 48 percent of these remaining performance obligations over the next 12 months, with the balance recognized thereafter. Revenue from remaining performance obligations for services as of March 31, 2018 was not material.
12. Immaterial Correction of Prior Period Financial Statements

As described in Note 17 in our Notes to Consolidated Financial Statements in the Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on February 26, 2018, we revalued our net deferred tax assets to implement the federal Tax Cuts and Jobs Act (the "Tax Act") which the federal government passed on December 22, 2017. During the year ended December 31, 2017, immaterial errors were discovered in prior periods in the reporting of the GAAP income tax expense associated with the stock-based compensation for certain of our executive officers. While we have concluded that the impact of these errors on our previously-issued unaudited condensed consolidated statements of income and unaudited condensed consolidated statements of comprehensive income was not material, we have revised our previously-reported unaudited condensed consolidated statements of income and unaudited condensed consolidated statements of comprehensive income for the three months ended March 31, 2017. The revisions include a decrease to GAAP net income for the first quarter of 2017 of $0.1 million, as a result of the increase to our GAAP income tax expense for the first quarter of 2017. For the first quarter of 2017, there was no impact on previously reported cash flows, pre-tax income and non-GAAP results. The revisions to our unaudited condensed consolidated statements of income and unaudited condensed consolidated statements of comprehensive income for the three months ended March 31, 2017 are as follows (in thousands, except per share amounts):

UltiPro provides our customers with tools to analyze workforce trends for better decision making, identify high-performing talent within their organizations, predict who future high-performers and retention risks 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-basedweb-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,profits while 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 enterprise companies, which we define as organizations with 2,501 or more employees, including those with 10,000 or more employees;employees and larger; mid-market companies, which we define as those having 501-2,500 employees; and strategic market companies, which we define as those having 100-500 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 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; (vi) benefits enrollment; (vii) time management; (viii) payment services (formerly referred to as “tax filing”);services; (ix) wage attachments; (x) UltiPro affordable care actACA toolkit and (xi) other optional features (collectively, “Optional Capabilities”), which are described below.


.
All Optional Capabilities are priced solely on a subscription basis. Some of the Optional Capabilities are available to enterprise, mid-market and strategic market customers while others are available exclusively to either 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 and transaction costs for business combinations ("Non-GAAP Operating Income"); and (iii) retention of our customers once our solutions are sold (“Customer Retention”). For the three months ended September 30, 2017,March 31, 2018, our (i) recurring revenues grew by 21.6%24.5%, compared with the same period in 2016,2017, and (ii) Non-GAAP Operating Income was $53.3$56.1 million, or 22.6%20.3% of total revenues, as compared with $38.9$37.7 million, or 19.7%16.5% of total revenues, for the same period in 2016. For the nine months ended September 30, 2017, our (i) recurring revenues grew by 23.0%, compared with the same period in 2016, and (ii) Non-GAAP Operating Income was $138.0 million, or 20.0% of total revenues, as compared with $112.4 million, or 19.7% of total revenues, for the same period in 2016.2017. As of September 30, 2017,March 31, 2018, our Customer Retention, on a trailing twelve-month basis, was approximately 96% for our recurring revenue cloud customer 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”).
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.changed with the exception of our revenue recognition policy due to the adoption of Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“Topic 606”).
Fair Value of Financial Instruments
Ultimate's financial instruments, consisting of cash and cash equivalents, accounts receivable, and accounts payable approximated fair value (due to their relatively short maturity) as of September 30, 2017 and December 31, 2016. Marketable securities included in funds held for customers and the related obligations consist primarily of securities classified as available-for-sale and are recorded at fair value on a recurring basis.

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 nine months ended September 30, 2017, compared with the same periods in 2016, total revenues increased by $39.1 million and $118.6 million, respectively, and the combination of our total cost of revenues and operating expenses ("Total Costs") increased by $33.3 million and $120.5 million, respectively. This resulted in an increase in our operating income of $5.9 million for the three months ended September 30, 2017 and a decrease in our operating income of $1.9 million for the nine months ended September 30, 2017. The increases in the Total Costs for the three and nine months ended September 30, 2017 included the impact of $9.5 million and $27.5 million, respectively, of non-cash stock-based compensation, discussed below.
During the three and nine months ended September 30, 2017, as compared with the same periods in 2016, our non-cash stock-based compensation expense increased $8.7 million and $26.8 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 2017, in connection with the CIC Plan Revisions accounted for $5.8 million of the $8.7 million increase in our non-cash stock-based compensation expense for the three months ended September 30, 2017 and $16.3 million of the $26.8 million increase in our non-cash stock-based compensation expense for the nine months ended September 30, 2017.
Also included in the non-cash stock-based compensation expense increase in 2017 were the effects of new grants in the period 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):

Our net income for the three and nine months ended September 30, 2017 decreased $63 thousand and $0.4 million respectively, in comparison with the same period last year, primarily as a result of the increase in non-cash stock-based compensation expense changes (described above), partially offset by a reduction in our provision for income taxes due to the adoption of ASU 2016-09.

Revenues
Our revenues are derived from recurring revenues and services revenues.
Total revenues increased 19.9%21.1% to $236.1$276.8 million for the three months ended September 30, 2017March 31, 2018 from $197.0$228.5 million for the three months ended September 30, 2016 and 20.8% to $689.3 million for the nine months ended September 30, 2017 from $570.7 million for the nine months ended September 30, 2016.March 31, 2017.

Recurring revenues, primarily consisting of subscriptionsubscription-based SaaS revenues, from cloud-based UltiPro, increased 21.6%24.5% to $203.1$236.6 million for the three months ended September 30, 2017,March 31, 2018, from $167.0$190.0 million for the three months ended September 30, 2016 and 23.0% to $588.2 million for the nine months ended September 30, 2017, from $478.3 million for the nine months ended September 30, 2016.March 31, 2017. The increasesincrease for the three and nine months ended September 30, 2017,March 31, 2018, in cloudrecurring revenues, werewas primarily based on the revenue impact of incremental units sold to customers that have processed their first payroll using UltiPro (or gone "Live") since September 30, 2016,March 31, 2017, including the UltiPro core product and, to a lesser extent, Optional Capabilities of UltiPro. Cloud subscriptionsubscription-based SaaS 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 was approximately 96% as of September 30, 2017March 31, 2018 (calculated on a 12-month rolling basis), which comparesis consistent with approximately 97% for the comparablesame period of 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 10.3%4.3% to $33.1$40.2 million for the three months ended September 30, 2017March 31, 2018 from $30.0$38.5 million for the three months ended September 30, 2016 and 9.3% to $101.1 million for the nine months ended September 30, 2017 from $92.5 million for the nine months ended September 30, 2016.March 31, 2017. The increasesincrease in services revenues for the three- and nine-month periods werethree-month period was primarily due to an increase in other services mainly attributable to our print services for certain customers and, to a lesser extent, additional implementation revenues to support increased sales, from both Ultimate's implementation consultants as well as third party implementation partners.
As discussed in our Quarterly Report on Form 10-Q for the period ended June 30, 2017, filed with the Securities and Exchange Commission (the “SEC”) on August 8, 2017, as a result of an increase in the number 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 enterprise backlog have expanded by an average of 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, with a concentration of the impact expected in the fourth quarter 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.sales.
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 16.5%16.8% to $88.7$104.8 million for the three months ended September 30, 2017,March 31, 2018, from $76.2$89.7 million for the three months ended September 30, 2016 and 19.0% to $262.6 million for the nine months ended September 30, 2017, from $220.7 million for the nine months ended September 30, 2016.March 31, 2017.
Cost of recurring revenues increased 19.2%25.6% to $52.6$62.9 million for the three months ended September 30, 2017March 31, 2018 from $44.1$50.1 million for the three months ended September 30, 2016 and 22.7% to $155.2 million for the nine months ended September 30, 2017 from $126.5 million for the nine months ended September 30, 2016.March 31, 2017. The increasesincrease in the cost of recurring revenues for the three- and nine-month periods werethree-month period was primarily due to increases in both cloud costs and Customer Support costs, as described 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 modulemodules becoming available for itstheir intended use during December 2016.since March 31, 2017.
For the three and nine months ended September 30, 2017,March 31, 2018, the increase in cloud costs werewas 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 nine months ended September 30, 2017 wereMarch 31, 2018 was primarily due to higher labor costs commensurate with the growth in the number of cloud customers serviced.
Cost of services revenues increased 12.7%5.7% to $36.1$41.9 million for the three months ended September 30, 2017March 31, 2018 from $32.1$39.6 million for the three months ended September 30, 2016 and 14.1% to $107.5 million for the nine months ended

September 30, 2017 from $94.2 million for the nine months ended September 30, 2016.March 31, 2017. The increasesincrease in cost of services revenues for the three- and nine-month periods werethree-month period was primarily due to the increased cost of implementation, including higher labor and related costs, (particularly in association with the increased number of billable consultants), costs associated with the timing of one of our all-team national meetings for the services organization which was held during the three months ended September 30, 2017 but was held in the second fiscal quarter ended June 30, 2016 in the prior year and, to a lesser extent, the increased use of third party implementation partners.
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 17.8%2.6% to $65.1$71.2 million for the three months ended September 30, 2017March 31, 2018 from $55.2$69.4 million for the three months ended September 30, 2016 and 21.1% to $201.4 million for the nine months ended September 30, 2017 from $166.3 million for the nine months ended September 30, 2016.March 31, 2017. The increasesincrease in sales and marketing expenses for the three- and nine-month periods werethree-month period was 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 inexpenses, partially offset by lower sales commissions resulting from the increased labor and related costs for the three and nine months ended September 30, 2017 was a portionadoption 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 terminated. Under the terms of the applicable change in control plans, we were required to provide each such senior officer with “comparable value” with respectTopic 606 due 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.longer amortization period under this new standard.

Research and Development
Research and development expenses consist primarily of software development personnel costs. Research and development expenses increased 21.2%29.9% to $38.4$47.0 million for the three months ended September 30, 2017March 31, 2018 from $31.7$36.2 million for the three months ended September 30, 2016 and 24.1% to $109.6 million for the nine months ended September 30, 2017 from $88.3 million for the nine months ended September 30, 2016.March 31, 2017. The increasesincrease in research and development expenses for the three- and nine-month periods werethree-month period was 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 September 30,March 31, 2018 and March 31, 2017, and September 30, 2016, we capitalized a total of $13.9$14.6 million (including $1.0 million in non-cash stock-based compensation) and $9.2$12.6 million (including $0.9$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 nine months ended September 30, 2017 and September 30, 2016, we capitalized a total of $40.1 million (including $3.0 million in non-cash stock-based compensation) and $26.2 million (including $2.8 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 and nine months ended September 30, 2017.March 31, 2018. During the three and nine months ended September 30, 2017,March 31, 2018, there was $1.0$1.8 million and $3.1 million respectively, of amortization associated with certain product modules of the Development Project which were ready for their intended use.use, as compared with $1.0 million for the same period of the prior year. 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 16.5%5.0% to $29.5$31.7 million for the three months ended September 30, 2017March 31, 2018 from $25.3$30.2 million for the three months ended September 30, 2016 and 32.1% to $91.1 million for the nine months ended September 30, 2017 from $69.0 million for the nine months ended September 30, 2016.March 31, 2017. The increasesincrease in general and administrative expenses for the three- and nine-month periods werethree-month period was 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 and an increase in the provision for doubtful accounts, and a portion of certain non-cash, stock-based compensation expenses relating to grants of restricted stock awards given to certain senior officers whose rights to receive cash payments upon a change in control of Ultimate were 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 and nine months ended September 30, 2017,March 31, 2018 included a consolidated tax provision of $9.6 million and $7.1 million, respectively.$1.3 million.  The effective income tax rate for the three and nine months ended September 30, 2017March 31, 2018 was 67.1% and 29.6%, respectively.5.8%. Income taxes for the three and nine months ended September 30, 2016 (as restated for the effect of ASU 2016-09)March 31, 2017 included a consolidated provisiontax benefit of $3.8 million and $8.7 million, respectively.$4.2 million. The effective income tax rate for the three and nine months ended September 30, 2016March 31, 2017 was 44.4%(140.1)%. The effective income tax rate for the three months ended March 31, 2018 included the reduction in the federal statutory tax rate from 35% to 21% effective January 1, 2018 due to the passing of the federal Tax Cuts and 33.3%, respectively. The changeJobs Act (the “Tax Act”) by the federal government on December 22, 2017. Although the statutory tax rate decreased, the increase in the effective income tax rate for the three and nine months ended September 30, 2017, as compared withMarch 31, 2018 is primarily attributable to a significantly higher pre-tax net income for the three and nine months ended September 30, 2016, was primarily dueMarch 31, 2018. Consequentially, the impact (benefit) to an increase in the recognitioneffective tax rate of the excess tax benefits in the three and nine months ended September 30, 2017 as compared to September 30, 2016 resulting from the adoptionapplication of ASU 2016-09 was significantly lower for the three months ended March 31, 2018. For the three months ended March 31, 2018 and March 31, 2017, we realized an excess tax benefit of $8.1 million and $7.1 million, respectively, from the application of ASU 2016-09. ASU 2016-09 requires thatFor the twelve months ended December 31, 2017, we realized an excess tax benefits or deficiencies be recorded as discrete items inbenefit of $20.9 million from the interim reporting period in which they occur and not included in the annual effective tax rate. This was partially offset by an increase in non-deductible expenses, primarily stock based compensation, and a resulting higher ratioapplication of non-deductible expenses to pre-tax income.ASU 2016-09.


At December 31, 2016,2017, we had approximately $148.5$135.0 million of net operating loss carryforwards for Federalfederal income tax reporting purposes available to offset future taxable income. Prior 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, were credited to paid-in-capital and deferred tax asset 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-based compensation were 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 2017 through 2035, for Federalfederal and state income tax reporting purposes, respectively.purposes. 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, 2016,2017, we had $7.2$8.9 million of gross unrecognized tax benefits resulting from a research and development credit attributable to the years 1998 through 2016,2017, 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 $71.5$22.1 million of deferred tax assets, net of deferred tax liabilities, as of September 30, 2017.March 31, 2018. 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

The Securities and Exchange Commission ("SEC") staff issued Staff Accounting Bulletin No. 118 ("SAB 118"), which provides a measurement period that should not extend beyond one year from the enactment date for companies to complete the accounting required. The Company, in accordance with SAB 118, will record and revise reasonable estimates of the income tax effects of the Tax Act in the first period further analysis and future guidance is available. For the current and subsequent tax years, we will continue to assert the position of indefinite re-investment of earnings in Canada and Singapore. We will apply the exception to the comprehensive recognition of deferred income taxes to the undistributed earnings of our foreign subsidiary, Thesubsidiaries, the Ultimate Software Group of Canada, Inc. (“and the Ultimate Canada”). Accordingly, deferred incomeSoftware Group of Asia, PTE. LTD. The indefinite reinvestment criteria includes state taxes wereand withholding taxes that arise from repatriation under IRC Section 965(n), which are 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 September 30, 2017,March 31, 2018, we had $137.9$147.9 million in cash, cash equivalents and short-term corporate investments in marketable securities (collectively, "Cash"), reflecting a net increasedecrease of $48.6$17.2 million since December 31, 2016.2017.  The total increasedecrease in Cash for the nine-monththree month period was primarily from cash provided by operations of $139.3 million and proceeds from the issuances of Common Stock from employee and non-employee director stock option exercises of $5.0 million, partially offset by cash purchases of property and equipment (including principal payments on financed equipment) of $66.7 million (which includes $37.1 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 of $37.3$50.3 million, cash purchases of property and equipment (including principal payments on financed equipment) of $24.4 million (which includes $13.6 million of capitalized labor costs and third party consulting fees, paid in cash, associated with the Development Project), partially offset by cash provided by operations of $56.6 million and proceeds from the issuances of Common Stock from employee and non-employee director stock option exercises of $2.5 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 $24.0$10.2 million during the ninethree months ended September 30, 2017March 31, 2018 to $139.3$56.6 million, as compared with $115.3$46.3 million for the ninethree months ended September 30, 2016.March 31, 2017. This increase was primarily due to an increase in cash operating income (after adjusting for non-cash expenses) of $35.1million and increased$19.9 million, partially offset by decreased cash from working capital, partially offset by increased cash paid for prepaid commissions (short- and long-term) in association with sales made during the nine-month period.capital.
The net cash used in investing activities was $63.5$665.3 million for the ninethree months ended September 30, 2017,March 31, 2018, as compared with a net cash inflowoutflow of $448.9$472.3 million for the ninethree months ended September 30, 2016.March 31, 2017.  The decreaseincrease of $512.4$193.0 million was primarily attributable to a net change in funds received from our customers using the UltiPro payment services offering (“UltiPro Payment Services”) of $560.6$173.2 million, and an increase in cashthe purchases of property and equipmentmarketable securities of $12.3$22.1 million (which includes purchases for the period of $119.2 million of funds held for customers being invested in marketable securities in addition to our corporate funds), partially offset by an increase in the maturities of marketable securities of $28.2$2.4 million (which includes the maturities for the period of $88.4$44.3 million of marketable securities originally purchased with funds held for customers in addition to our corporate funds), and an increase in the purchases of marketable securities of $126.3 million (which includes purchases for the period of $149.2 million of funds held for customers being invested in marketable securities in addition to our corporate funds). During the ninethree months ended September 30, 2017,March 31, 2018, we capitalized software development costs related to the Development Project totaling $40.1$14.6 million (including $3.0$1.0 million from the non-cash impact of capitalized stock-based compensation expense), which was classified as property and equipment. We 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 inprovided by financing activities was $24.7$596.9 million for the ninethree months ended September 30, 2017,March 31, 2018, as compared with $579.5$425.8 million net cash used inprovided by financing activities for the ninethree months ended September 30, 2016.March 31, 2017. The $554.8$171.0 million decreaseincrease in cash used inprovided by financing activities was primarily related to a decrease of $29.7 million in cash used for the repurchases of shares of our Common Stock under our Stock Repurchase Plan, a net change of $540.4$188.6 million in customer funds obligations for our UltiPro Payment Services and an increase of $0.9 million in the netcash proceeds from issuancesthe issuance of our Common Stock of $1.4 million and a decrease in cash used for the repayments of other borrowings of $0.3 million,stock option exercises, partially offset by an increase of $16.6$16.7 million in cash used to settle employee tax withholdingwith

holding liabilities upon the vesting of their restricted stock awards and restricted stock unit awards, and an increase of $0.4 million in cash used for principalthe payments on capital lease obligations.of other liabilities of $1.8 million.
Days sales outstanding (or "DSOs"), calculated on a trailing three-month basis, as of September 30, 2017March 31, 2018 were 7263 days as compared with 6964 days as of September 30, 2016. The increase of three days was associated with stronger sales bookings during the third quarter ofMarch 31, 2017.
Deferred revenues were $188.4$202.2 million at September 30, 2017,March 31, 2018, as compared with $174.0$198.9 million at December 31, 2016.2017. The increase of $14.4$3.4 million in deferred revenues was primarily due to incremental 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 September 30, 2017,March 31, 2018, 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 September 30, 2017,March 31, 2018, 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 believesWe believe that this non-GAAP measure of financial results provides useful information to management and investors regarding certain financial and business trends relating to Ultimate'sour financial condition and results of operations. Ultimate's managementManagement uses this non-GAAP result to compare Ultimate'sour 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'sour 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 itswe present our non-GAAP financial measure in connection with itsour GAAP result. UltimateWe strongly urgesurge investors and potential investors in Ultimate'sour securities to review the reconciliation of itsour 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'sOur 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 nine months ended September 30, 2017,March 31, 2018, stock-based compensation expense was $38.0$33.2 million and $111.2 million, respectively, on a pre-tax basis. For the three and nine months ended September 30, 2016,March 31, 2017, stock-based compensation expense was $29.3$33.9 million and $84.4 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 doeswe do not consider part of ongoing operations when assessing its financial performance. Ultimate believesWe believe 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 nine months ended September 30,March 31, 2018, the amortization of acquired intangible assets was $0.8 million. For the three months ended March 31, 2017, the amortization of acquired intangible assets was $0.8 million and $2.3 million, respectively. For the three and nine months ended September 30, 2016, the amortization of acquired intangible assets was $0.3 million and $0.8 million, respectively.million. 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 believesWe believe 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 September 30, 2017,March 31, 2018, total corporate investments in available-for-sale marketable securities were $12.2$4.3 million. As of September 30, 2017,March 31, 2018, total investments with customer funds in available-for-sale marketable securities were $209.1$283.5 million.
As of September 30, 2017,March 31, 2018, 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 1.3%2.3% and 2.0% per annum)annum, respectively).
To illustrate the potential impact of changes in interest rates, Ultimate has performed an analysis based on its September 30, 2017March 31, 2018 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 corporate portfolio of approximately $50$5 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$2.0 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 corporate portfolio of approximately $50$5 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$2.0 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 September 30, 2017,March 31, 2018, 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 September 30, 2017March 31, 2018 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. Effective January 1, 2018, we adopted Accounting Standards Codification 606, Revenue from Contracts with Customers (“Topic 606”). Although Topic 606 is expected to have an immaterial impact on our ongoing net income, we did implement changes to our processes related to revenue recognition, deferred contract costs and the control activities within them. These included the development of new policies based on the five-step model provided in Topic 606, ongoing contract review requirements, and gathering of information provided for disclosures.
