OVERVIEW AND BASIS OF PRESENTATION

(1)OVERVIEW AND BASIS OF PRESENTATION

Summary of Business

TTEC Holdings, Inc. (“TTEC”, “the Company”) (formerly known as TeleTech Holdings, Inc. until the name was changed in January 2018) is a global customer experience company that designs, builds and operates omnichannel customer experiences on behalf of some of the world's most innovative brands. The Company helps large global companies increase revenue and reduce costs by delivering personalized customer experiences across every interactional channel and phase of the customer lifecycle as an end-to-end provider of customer engagement services, technologies, insights and innovations. TTEC’s 50,500 employees serve clients in the automotive, communication, financial services, government, healthcare, logistics, media and entertainment, retail, technology, transportation and travel industries via operations in the U.S., Australia, Belgium, Brazil, Bulgaria, Canada, China, Costa Rica, Germany, Hong Kong, India, Ireland, Lebanon, Macedonia, Mexico, New Zealand, the Philippines, Poland, Singapore, South Africa, Thailand, Turkey, the United Arab Emirates, and the United Kingdom.

Basis of Presentation

The Consolidated Financial Statements are comprised of the accounts of TTEC, its wholly owned subsidiaries, its 55% equity owned subsidiary Percepta, LLC, and its 100% interest in Motif, Inc. (see Note 2). All intercompany balances and transactions have been eliminated in consolidation.

The unaudited Consolidated Financial Statements do not include all of the disclosures required by accounting principles generally accepted in the U.S. (“GAAP”), pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The unaudited Consolidated Financial Statements reflect all adjustments which, in the opinion of management, are necessary to state fairly the consolidated financial position of the Company and the consolidated results of operations and comprehensive income (loss) and the consolidated cash flows of the Company. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2018.

These unaudited Consolidated Financial Statements should be read in conjunction with the Company’s audited Consolidated Financial Statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Use of Estimates

The preparation of the Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions in determining the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenue and expenses during the reporting period. On an on-going basis, the Company evaluates its estimates including those related to derivatives and hedging activities, income taxes including the valuation allowance for deferred tax assets, self-insurance reserves, litigation reserves, restructuring reserves, allowance for doubtful accounts, contingent consideration, and valuation of goodwill, long-lived and intangible assets. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ materially from these estimates under different assumptions or conditions.

Recently Issued Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers”. ASU 2014-09 provides new guidance related to how an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, ASU 2014-09 specifies new accounting for costs associated with obtaining or fulfilling contracts with customers and expands the required disclosures related to revenue and cash flows from contracts with customers. While ASU-2014-09 was originally effective for fiscal years and interim periods within those years beginning after December 15, 2016, in August 2015, the FASB issued ASU 2015-14, “Deferral of Effective Date”, deferring the effective date by one year, to be effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Earlier adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. ASU 2014-09 can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, with early application not permitted. In June 2017, FASB issued ASU 2017-10, “Service Concession Arrangements”, which will be adopted along with the ASU 2014-09 guidance.

On January 1, 2018, the Company adopted ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), using the modified retrospective method. The adoption of ASC 606 resulted in the deferral of certain fees that had already been recognized in prior periods. The Company recorded a net reduction to opening retained earnings of $10.0 million, net of tax, as of January 1, 2018 due to the cumulative impact of adopting ASC 606, summarized as follows (in thousands):

The ASC 606 adjustments pertain to the timing of revenue recognition associated with upfront training fees on certain contracts. Revenues and associated costs for reporting periods beginning after January 1, 2018 are recognized and presented in compliance with the provisions of ASC 606. Consistent with the modified retrospective method of adoption, the Company has not adjusted prior period amounts which continue to be reported in accordance with the Company’s historic revenue accounting policy and principles.

In accordance with the new revenue standard requirements, the disclosure of the impact of adoption on the Company’s consolidated income statement and balance sheet was as follows (in thousands):

In connection with the adoption of ASC 606, certain of the Company’s revenue and related polices have been modified; all policies relevant to ASC 606 have been included below.

Revenue Recognition

The Company recognizes revenue from contracts and programs when control of the promised goods or services is transferred to the customers, in an amount that reflects the consideration it expects to be entitled to in exchange for those goods or services. Revenue is recognized when or as performance obligations are satisfied by transferring control of a promised good or service to a customer. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. Performance obligation is the unit of accounting for revenue recognition under the provisions of ASC 606. A contract’s transaction price is allocated to each distinct performance obligation in recognizing revenue.

The Business Process Outsourcing (“BPO”) inbound and outbound service fees are based on either a per minute, per hour, per FTE, per transaction or per call basis, which make up the majority of our contracts. These contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. For example, services for the training of the Company’s agents (which are separately billable to the customer) are a separate promise in the BPO contracts, but they are not distinct from the primary service obligations to transfer services to the customers. The performance of the customer service by the agents is highly dependent on the initial, growth, and seasonal training services provided to the agents during the life of a program. The training itself is not considered to have value to the customer on a standalone basis, and therefore, training on a standalone basis cannot be considered a separate unit of accounting. The Company therefore defers revenue from certain training services that are rendered mainly upon commencement of a new client contract or program, including seasonal programs. Revenue is also deferred when there is significant growth in an existing program. Accordingly, recognition of initial, growth, and seasonal training revenues and associated costs (consisting primarily of labor and related expenses) are deferred and amortized over the period of economic benefit. With the exception of training which is typically billed upfront and deferred, the remainder of revenue is invoiced on a monthly or quarterly basis as services are performed and do not create a contract asset or liability.

In addition to revenue from BPO services, revenue also consists of fees from services for program launch, professional consulting, fully-hosted or managed technology and learning innovation services. The contracts containing these service offerings may contain multiple performance obligations. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using the best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which the Company forecasts its expected costs of satisfying a performance obligation and then adds an appropriate margin for that distinct good or service. The Company forecasts its expected cost based on historical data, current prevailing wages, direct and indirect other costs incurred in recently completed contracts, market conditions, and client specific other cost considerations. For these services, the point at which the transfer of control occurs determines when revenue is recognized in a specific reporting period. Where there are product sales, the attribution of revenue is made when FOB-destination delivery occurs (control transfers), which is the standard shipment terms, and therefore at a point in time. Where services are rendered to a customer, the attribution is aligned with the progress of work and is recognized over time (i.e. based on measuring the progress toward complete satisfaction of a performance obligation using an output method or an input method). Where output method is used, revenue is recognized on the basis of direct measurements of the value to the customer of the goods or services transferred relative to the remaining goods or services promised under the contract. The majority of the Company’s services is recognized over time using the input method in which revenue is recognized on the basis of efforts or inputs toward satisfying a performance obligation (for example, resources consumed, labor hours expended, costs incurred, or time elapsed) relative to the total expected inputs to satisfy the performance obligation. The measures used provide faithful depiction of the transfer of goods or services to the customers. For example, revenue is recognized on certain consulting contracts based on labor hours expended as a measurement of progress where the consulting work involves input of consultants’ time. The progress is measured based on the hours expended over total number of estimated hours included in the contract multiplied by the total contract consideration. The contract consideration can be a fixed price or an hourly rate, and in either case, the use of labor hours expended as an input measure provides a faithful depiction of the transfer of services to the customers. Deferred revenues for these services represent amounts collected from, or invoiced to, customers in excess of revenues recognized. This results primarily from i) receipt of license fees that are deferred due to one or more of the revenue recognition criteria not being met, and ii) the billing of annual customer support agreements, annual managed service agreements, and billings for other professional services that have not yet been performed by the Company. The Company records amounts billed and received, but not earned, as deferred revenue. These amounts are recorded in Deferred revenue as a component of Other long-term liabilities in the accompanying Consolidated Balance Sheets based on the period over which the Company expects to render services. Costs directly associated with revenue deferred, consisting primarily of labor and related expenses, are also deferred and recognized in proportion to the expected future revenue from the contract.

Variable consideration exists in contracts for certain client programs that provide for adjustments to monthly billings based upon whether the Company achieves, exceeds or fails certain performance criteria. Adjustments to monthly billings consist of contractual bonuses/penalties, holdbacks and other performance based conditions. Variable consideration is estimated at contract inception at its most likely value and updated at the end of each reporting period as additional performance data becomes available. Revenue related to such variable consideration is recognized only to the extent that a significant reversal of any incremental revenue is not considered probable.

Contract modifications are routine in the performance of the customer contracts. Contracts are often modified to account for customer mandated changes in the contract specifications or requirements, including service level changes. In most instances, contract modifications relate to goods or services that are incremental and distinctly identifiable, and, therefore, are accounted for prospectively.

Incremental Costs to Obtain a Contract

Direct and incremental costs to obtain or fulfill a contract are capitalized, and the capitalized costs are amortized over the corresponding period of benefit, determined on a contract by contract basis. The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects to recover those costs. The incremental costs of obtaining a contract are those costs that the Company incurs to obtain a customer contract that it would not have incurred if the contract had not been obtained. Contract acquisition costs consist primarily of payment of commissions to sales personnel and are incurred when customer contracts are signed. The deferred sales commission amounts are amortized based on the expected period of economic benefit and are classified as current or non-current based on the timing of when they are expected to be recognized as an expense. Costs to obtain a contract that would have been incurred regardless of whether the contract was obtained are recognized as an expense when incurred, unless those costs are explicitly chargeable to the customer regardless of whether the contract is obtained. Sales commissions are paid for obtaining new clients only and are not paid for contract renewals or contract modifications. Capitalized costs of obtaining contracts are periodically reviewed for impairment.

In certain cases, the Company negotiates an upfront payment to a customer in conjunction with the execution of a contract. Such upfront payments are critical to acquisition of new business and are often used as an incentive to negotiate favorable rates from the clients and are accounted for as upfront discounts for future services. Such payments are either made in cash at the time of execution of a contract or are netted against the Company’s service invoices. Payments to customers are capitalized as contract acquisition costs and are amortized in proportion to the expected future revenue from the contract, which in most cases results in straight-line amortization over the life of the contract. Such payments are considered a reduction of the selling prices of the Company’s products or services, and therefore, are accounted for as a reduction of revenue when amortized. Such capitalized contract acquisition costs are periodically reviewed for impairment taking into consideration ongoing future cash flows expected from the contract and estimated remaining useful life of the contract.

Practical Expedients and Exemptions

The Company does not disclose the value of unsatisfied performance obligations for contracts for which it recognizes revenue at the amount to which it has the right to invoice for services performed. Additionally, the Company’s standard payment terms are less than one year. Given the foregoing, the Company has elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. Some of the Company’s service contracts are short-term in nature with a contract term of one year or less. For those contracts, the Company has utilized the practical expedient in ASC 606-10-50-14 exempting the Company from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less. Pursuant to the Company’s election of the practical expedient under ASC 606-10-32-2A, sales, value add, and other taxes that are collected from customers concurrent with revenue-producing activities, which the Company has an obligation to remit to the governmental authorities, are excluded from revenue.

Other Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, “Leases”, which amends the existing accounting standards for lease accounting, including requiring lessees, to recognize most leases on their balance sheets related to the rights and obligations created by those leases and making targeted changes to lessor accounting. The ASU also requires new disclosures regarding the amounts, timing, and uncertainty of cash flows arising from leases. The ASU is effective for interim and annual periods beginning on or after December 15, 2018 and early adoption is permitted. The new leases standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The Company has assigned a project manager, is currently selecting an external consultant to assist through the project, is evaluating software solutions and other tracking methods, is assessing the impact on the consolidated financial statements and related disclosures, and determining the implementation approach.

In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows”. ASU 2016-15 is intended to reduce diversity in practice regarding how certain cash transactions are presented and classified in the Consolidated Statement of Cash Flows by providing guidance on eight specific cash flow issues. The ASU is effective for interim and annual periods beginning on or after December 15, 2017. The Company has adopted the new guidance effective January 1, 2018 and this adoption did not have a material impact on its cash flow or related disclosures.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities”. ASU 2017-12 amends and simplifies existing guidance for derivatives and hedges including aligning accounting with companies’ risk management strategies and increasing disclosure transparency regarding both the scope and results of hedging programs. The changes include designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The ASU is effective for interim and annual periods beginning after December 15, 2018 and early adoption is permitted. The Company is currently assessing the impact on the consolidated financial statements and related disclosures.

In February 2018, the FASB issued ASU 2018-02, “Income Statement - Reporting Comprehensive Income (Topic 220), Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”. ASU 2018-02 allows companies the option to reclassify stranded tax effects from Accumulated other comprehensive income (loss) (“AOCI”) to retained earnings resulting from the newly enacted corporate tax rate in the Tax Cuts and Jobs Act. If adopted, the ASU is effective in years beginning after December 15, 2018, and early adoption is permitted. The Company early adopted the new standard effective January 1, 2018 and the adoption did not have a material impact on its financial position.

ACQUISITIONS

(2)ACQUISITIONS AND DIVESTITURES

Berkshire Hathaway Specialty Concierge

On March 31, 2018, the Company, through its subsidiary Percepta, acquired certain assets from Berkshire Hathaway Specialty Concierge, LLC (“BH”) related to a customer engagement center and the related customer contracts. This acquisition is being accounted for as a business combination. These assets will be integrated into the Customer Management Services (“CMS”) segment.

The total cash paid was $1. In connection with the purchase, Percepta assumed the lease for the customer engagement center and entered into a transitional services agreement with BH to facilitate the transfer of the employees and business. Fair values were assigned to each purchased asset including $257 thousand for customer relationships, $330 thousand as a lease subsidy and $98 thousand for fixed assets. Based on the $1 purchase price, a gain on purchase of $685 thousand was recorded in the quarter ended March 31, 2018 and was included in Other income (expense) in the Consolidated Statements of Comprehensive Income (Loss).

Motif

On November 8, 2017, the Company agreed to acquire all of the outstanding shares in Motif, Inc., a California corporation (“Motif”). Motif is a digital trust and safety services company serving eCommerce marketplaces, online retailers, travel agencies and financial services companies. Motif provides omni-channel community moderation services via voice, email and chat from delivery centers in India and the Philippines via approximately 2,700 employees. Motif will be integrated into the Customer Management Services (“CMS”) segment.

The acquisition will be implemented through two separate transactions. In November 2017, the Company completed the acquisition of 70% of all outstanding shares in Motif from private equity and certain individual investors for $46.8 million, subject to customary representations and warranties, and working capital adjustments. The Company also agreed to purchase the remaining 30% interest in Motif from Motif’s founders (“founders’ shares”) no later than May 2020 (“30% buyout period”). The Company agreed to pay for the founders’ shares at a purchase price based on Motif’s fiscal year 2020’s adjusted normalized EBITDA, $5.0 million in cash, and 30% of the excess cash present in the business at the time of the buyout; or if the buyout occurs prior to May 2020, based on the trailing twelve months EBITDA, calculated from the most recently completed full monthly period ending prior to the date of the buyout triggering event, $5.0 million in cash, and 30% of the excess cash in the business at that point. In connection with this mandatory buyout, the Company has recorded a $29.8 million liability as of March 31, 2018 which is included in Other long-term liabilities in the Consolidated Balance Sheet. As a part of the transition, the Motif founders agreed to continue to stay as executives in the acquired business, at least through the 30% buyout period, as part of the Company’s CMS segment, and not to compete with the Company with respect to the acquired business.

The following summarizes the preliminary estimated fair values of the identifiable assets acquired and liabilities assumed as of the acquisition date (in thousands):

The estimates of fair value of identifiable assets acquired and liabilities assumed are preliminary, pending finalization of a valuation and tax returns, thus are subject to revisions that may result in adjustments to the values presented above.

The Motif customer relationships have been estimated based on the initial valuation and are amortized over an estimated useful life of 11 years. The goodwill recognized from the Motif acquisition is estimated to be attributable, but not limited to, the acquired workforce and expected synergies with CMS. None of the tax basis of the acquired intangibles and goodwill will be deductible for income tax purposes. The acquired goodwill and intangibles, and operating results of Motif are reported within the CMS segment from the date of acquisition.

Connextions

On April 3, 2017, the Company acquired all of the outstanding shares of Connextions, Inc., a health care customer service provider company, from OptumHealth Holdings, LLC. Connextions is being integrated into the health care vertical of the CMS segment of the Company. Connextions employed approximately 2,000 at several centers in the U.S.

The total cash paid at acquisition was $80 million. The purchase price was subject to customary representations and warranties, indemnities, and net working capital adjustment. In connection with the acquisition, the Company and OptumHealth (directly and through affiliates) also entered into long-term technology and customer services agreements, and into transition services agreements to facilitate the transfer of the business. The Company was required to pay an additional $1.8 million for the working capital adjustment, which was paid during the third quarter of 2017. Additionally, fair value adjustments related to the transition services agreements reduced the purchase price by $4.1 million resulting in a net purchase price of $77.7 million.

The following summarizes the fair values of the identifiable assets acquired and liabilities assumed as of the acquisition date (in thousands):


	Acquisition Date

In the fourth quarter of 2017, the Company finalized its valuation of Connextions for the acquisition date assets acquired and liabilities assumed and determined that no material adjustments to any of the balances were required.

The Connextions customer relationships will be amortized over a useful life of 12 years. The goodwill recognized from the Connextions acquisition is attributable, but not limited to, the acquired work force and expected synergies with CMS. None of the tax basis of the acquired intangibles and goodwill will be deductible for income tax purposes. The acquired goodwill and the operating results of Connextions are reported within the CMS segment from the date of acquisition.

Financial Impact of Acquired Businesses

2018 Acquisition

The acquired business purchased in the first three months of 2018 was not material to the Company's consolidated financial position or results of operations. The pro forma impact of the 2018 acquisition on the consolidated results of operations of the Company for the first three months of 2018 and 2017 as though the acquisitions occurred on January 1 was also not material.

2017 Acquisitions

The acquired businesses purchased in 2017 did not contribute any revenue and net income to the Company for the three months ended March 31, 2017.

The unaudited proforma financial results for the three months ended March 31, 2017 combines the consolidated results of the Company and its 2017 acquisitions assuming they had been completed on January 1, 2017. The reported revenue and net income of $338.3 million and $19.2 million would have been $384.0 million and $19.0 million for the three months ended March 31, 2017 on an unaudited proforma basis.

The unaudited pro forma consolidated results are not to be considered indicative of the results if these acquisitions occurred in the periods mentioned above, or indicative of future operations or results. Additionally, the pro forma consolidated results do not reflect any anticipated synergies expected as a result of the acquisition.

Assets and Liabilities Held for Sale

During the third quarter of 2016, the Company determined that one business unit from the Customer Growth Services (“CGS”) segment and one business unit from the Customer Strategy Services (“CSS”) segment would be divested from the Company’s operations. These business units met the criteria to be classified as held for sale. The Company had engaged a broker for both business units and was working with potential buyers for both business units. The Company took into consideration the discounted cash flow models, management input based on early discussions with brokers and potential buyers, and third-party evidence from similar transactions to complete the fair value analysis as there had not been a selling price determined at this point for either unit. For the two business units in CGS and CSS losses of $2.6 million and $2.7 million, respectively, were recorded as of December 31, 2016 in Loss on assets held for sale in the Consolidated Statements of Comprehensive Income (Loss). No adjustments have been made for the CSS business unit as this continues to be reflective of the fair value at March 31, 2018.

For the business unit in CGS, based on further discussion and initial offers, management determined that the estimated selling price assumed should be revised and an additional $3.2 million loss was recorded in June 30, 2017 and included in Loss on assets held for sale in the Consolidated Statements of Comprehensive Income (Loss). Effective December 22, 2017, the business unit was sold to The Search Agency (“TSA”) for an up-front payment of $245 thousand and future contingent earnout on the one year anniversary of the closing date. During the fourth quarter of 2017, a net $0.6 million gain was recorded in Loss on assets held for sale in the Consolidated Statements of Comprehensive Income (Loss).

The following table presents information related to the major components of assets and liabilities that were classified as held for sale in the Consolidated Balance Sheet as of March 31, 2018.

Investments

CaféX

In the first quarter of 2015, the Company invested $9.0 million in CafeX Communications, Inc. (“CaféX”) through the purchase of a portion of the Series B Preferred Stock of CaféX. CaféX is a provider of omni-channel web-based real time communication (WebRTC) solutions that enhance mobile applications and websites with in-app video communication and screen share technology to increase customer satisfaction and enterprise efficiency. TTEC anticipated deploying the CaféX technology as part of the TTEC customer experience offerings within the CMS business segment and as part of its Humanify platform. At December 31, 2015, the Company owned 17.2% of the total equity of CaféX. During the fourth quarter of 2016, the Company invested an additional $4.3 million to purchase a portion of the Series C Preferred Stock; $3.2 million was paid in the fourth quarter of 2016 and $1.1 million was paid in the first quarter of 2017. At March 31, 2018, the Company owns 17.2% of the total equity of CaféX. The investment is accounted for under the cost method of accounting. The Company evaluates its investments for possible other-than-temporary impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.

During the first quarter of 2018, the Company provided to CaféX $2.1 million in the form of a bridge loan which accrues interest at a rate of 12% until maturity or conversion, which will be no later than June 30, 2020. Based on certain events, the loan could convert into Series D preferred stock.

As of March 31, 2018, the Company evaluated the investment in CaféX for impairment due to a large anticipated sale of IP not being completed as planned during the first quarter, a shift in the strategy of the company, the loan balance with the external bank is now in default, and the lack of potential additional funding options as of March 31, 2018. It was determined that the fair value of the investment was zero and thus the investment should be impaired as of March 31, 2018. The Company recorded a $15.6 million write-off of the equity investment and the bridge loan which was included in Other income (expense) in the Consolidated Statements of Comprehensive Income (Loss).

Divestitures

Technology Solutions Group (“TSG”)

Effective June 30, 2017, the Company sold the Technology Solutions Group to SKC Communication Products, LLC (“SKC”) for an upfront payment of $250 thousand and future contingent royalty payments over the next 3 years. TSG had been included in the CTS segment. During the second quarter of 2017, a $30 thousand gain, which included the write-off of $0.7 million of goodwill, was recorded and included in the Consolidated Statements of Comprehensive Income (Loss). During the third quarter of 2017, a $141 thousand gain was recorded as a result of TSG delivering to SKC working capital in excess of the target set forth in the stock purchase agreement, and the gain was included in the Consolidated Statements of Comprehensive Income (Loss). During the fourth quarter of 2017 and first quarter of 2018, TTEC received $259 thousand and $794 thousand, respectively, related to royalty payments which were included in Other Income (expense) in the Consolidated Statements of Comprehensive Income (Loss) in the respective periods.

TTEC Spain Holdings SL

In the third quarter of 2017, the Company dissolved TTEC Spain Holdings SL, a fully owned foreign subsidiary domiciled in Spain. Upon complete liquidation, $3.2 million attributable to the accumulated translation adjustment component of equity has been removed from Accumulated other comprehensive income (loss) and recognized as part of the gain on liquidation. The $3.2 million gain is included in Other income (expense), net in the Consolidated Statements of Comprehensive Income (Loss) for the three and nine months ended September 30, 2017.

Subsequent Event

On April 30, 2018, the Company agreed to acquire all of the outstanding shares in Strategic Communications Services, Ltd (“SCS”).

Cash Flow Hedges

The Company enters into foreign exchange related derivatives. Foreign exchange derivatives entered into consist of forward and option contracts to reduce the Company’s exposure to foreign currency exchange rate fluctuations that are associated with forecasted revenue earned in foreign locations. Upon proper qualification, these contracts are designated as cash flow hedges. It is the Company’s policy to only enter into derivative contracts with investment grade counterparty financial institutions, and correspondingly, the fair value of derivative assets consider, among other factors, the creditworthiness of these counterparties. Conversely, the fair value of derivative liabilities reflects the Company’s creditworthiness. As of March 31, 2018, the Company has not experienced, nor does it anticipate, any issues related to derivative counterparty defaults. The following table summarizes the aggregate unrealized net gain or loss in Accumulated other comprehensive income (loss) for the three months ended March 31, 2018 and 2017 (in thousands and net of tax):

FAIR VALUE [Abstract]

FAIR VALUE

(7)FAIR VALUE

The authoritative guidance for fair value measurements establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires that the Company maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, similar assets and liabilities in markets that are not active or can be corroborated by observable market data.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

The following presents information as of March 31, 2018 and December 31, 2017 for the Company’s assets and liabilities required to be measured at fair value on a recurring basis, as well as the fair value hierarchy used to determine their fair value.

Accounts Receivable and Payable - The amounts recorded in the accompanying balance sheets approximate fair value because of their short-term nature.

Investments – The Company measures investments, including cost and equity method investments, at fair value on a nonrecurring basis when they are deemed to be other-than-temporarily impaired. The fair values of these investments are determined based on valuation techniques using the best information available, and may include market observable inputs, and discounted cash flow projections. An impairment charge is recorded when the cost of the investment exceeds its fair value and this condition is determined to be other-than-temporary. As of March 31, 2018, the investment in CaféX Communication, Inc., which consisted of the Company’s total $15.6 million investment was fully impaired to zero (See Note 2).

Debt - The Company’s debt consists primarily of the Company’s Credit Agreement, which permits floating-rate borrowings based upon the current Prime Rate or LIBOR plus a credit spread as determined by the Company’s leverage ratio calculation (as defined in the Credit Agreement). As of March 31, 2018 and December 31, 2017, the Company had $302.5 million and $344.0 million, respectively, of borrowings outstanding under the Credit Agreement. During the first quarter of 2018 outstanding borrowings accrued interest at an average rate of 2.8% per annum, excluding unused commitment fees. The amounts recorded in the accompanying Balance Sheets approximate fair value due to the variable nature of the debt based on Level 2 inputs.

Derivatives - Net derivative assets (liabilities) are measured at fair value on a recurring basis. The portfolio is valued using models based on market observable inputs, including both forward and spot foreign exchange rates, interest rates, implied volatility, and counterparty credit risk, including the ability of each party to execute its obligations under the contract. As of March 31, 2018, credit risk did not materially change the fair value of the Company’s derivative contracts.

The following is a summary of the Company’s fair value measurements for its net derivative assets (liabilities) as of March 31, 2018 and December 31, 2017 (in thousands):

Deferred Compensation Plan — The Company maintains a non-qualified deferred compensation plan structured as a Rabbi trust for certain eligible employees. Participants in the deferred compensation plan select from a menu of phantom investment options for their deferral dollars offered by the Company each year, which are based upon changes in value of complementary, defined market investments. The deferred compensation liability represents the combined values of market investments against which participant accounts are tracked.

Contingent Consideration — The Company recorded contingent consideration related to a revenue servicing agreement with Welltok in the fourth quarter of 2016, in which a maximum of $1.25 million would be paid over eight quarters based on the dollar value of revenue earned by the Company. The contingent payable was recognized at fair value of $1.25 million as of December 31, 2016. As required, payments totaling $851 thousand were completed during 2017. The final payment of $399 thousand was completed during the first quarter of 2018 and the liability has been reduced to zero.

INCOME TAXES	3 Months Ended
INCOME TAXES	Mar. 31, 2018
INCOME TAXES [ABSTRACT]
INCOME TAXES	(8)INCOME TAXES The United States recently enacted comprehensive tax reform legislation known as the Tax Cuts and Jobs Act (the "2017 Tax Act") that, among other things, reduces the U.S. federal corporate income tax rate from 35% to 21% and implements a territorial tax system, but imposes an alternative “base erosion and anti-abuse tax” (“BEAT”), and an incremental tax on global intangible low taxed foreign income (“GILTI”) effective January 1, 2018. The Company’s selection of an accounting policy with respect to both the new GILTI and BEAT rules is to compute the related taxes in the period the entity becomes subject to GILTI. A reasonable estimate of the effects of these provisions has been included in the first quarter financial statements. The ultimate impact of the 2017 Tax Act may materially differ from the provisional amounts recorded, due to, among other things, additional analysis, changes in interpretations and assumptions we have made, additional regulatory guidance that may be issued, and actions we may take as a result of the Tax Act. In addition, foreign and state governments may enact tax laws in response to the Tax Act that could result in further changes to global taxation and materially affect our financial position and results of operations. We expect to complete our analysis of the impacts of the 2017 Tax Act within the measurement period in accordance with SAB 118. The Company accounts for income taxes in accordance with the accounting literature for income taxes, which requires recognition of deferred tax assets and liabilities for the expected future income tax consequences of transactions that have been included in the Consolidated Financial Statements. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using tax rates in effect for the year in which the differences are expected to reverse. Quarterly, the Company assesses the likelihood that its net deferred tax assets will be recovered. Based on the weight of all available evidence, both positive and negative, the Company records a valuation allowance against deferred tax assets when it is more-likely-than-not that a future tax benefit will not be realized. As of March 31, 2018, the Company had $16.5 million of gross deferred tax assets (after a $ 9.5 million valuation allowance) and net deferred tax assets (after deferred tax liabilities) of $5.0 million related to the U.S. and international tax jurisdictions whose recoverability is dependent upon future profitability. The effective tax rate for the three months ended March 31, 2018 and 2017 was 26.2% and 21.1%, respectively. The Company’s U.S. income tax returns filed for the tax years ending December 31, 2014 to present, remain open tax years. The Company has been notified of the intent to audit, or is currently under audit of, income taxes for Canada for tax years 2009 and 2010, the Philippines for tax year 2015, Ireland for tax year 2016 and the state of Minnesota in the United States for tax years 2014 through 2016. Although the outcome of examinations by taxing authorities are always uncertain, it is the opinion of management that the resolution of these audits will not have a material effect on the Company’s Consolidated Financial Statements. The Company successfully closed their audit in the second quarter of 2017 in Hong Kong for the tax year 2014 with no material changes. The Company also recorded a benefit in the amount of $0.8 million in the financial statements during the fourth quarter of 2017 related to the favorable resolution of tax audits. The Company has been granted “Tax Holidays” as an incentive to attract foreign investment by the government of the Philippines. Generally, a Tax Holiday is an agreement between the Company and a foreign government under which the Company receives certain tax benefits in that country, such as exemption from taxation on profits derived from export-related activities. In the Philippines, the Company has been granted multiple agreements with an initial period of four years and additional periods for varying years, expiring at various times between 2011 and 2020. The aggregate effect on income tax expense for the three months ended March 31, 2018 and 2017 was approximately $1.8 million and $3.1 million, respectively, which had a favorable impact on diluted net income per share of $0.04 and $0.07, respectively.

(9)RESTRUCTURING CHARGES, INTEGRATION CHARGES AND IMPAIRMENT LOSSES

Restructuring Charges

During the three months ended March 31, 2018 and 2017, the Company continued restructuring activities primarily associated with reductions in the Company’s capacity, workforce and related management in several of the segments to better align the capacity and workforce with current business needs.

During 2017, several restructuring activities were completed related to the purchase of Connextions (see Note 2) including the closure of two delivery centers that came with the acquisition. During 2017, a net $0.4 million severance accrual was recorded in relation to these closures. In conjunction with closing these two delivery centers, a $0.6 million termination fee and a $1.4 million net lease liability and applicable expenses were recorded as of December 31, 2017. These net charges were included in the Consolidated Statements of Comprehensive Income (Loss) during the year ended December 31, 2017.

A summary of the expenses recorded in Restructuring and integration charges, net in the accompanying Consolidated Statements of Comprehensive Income (Loss) for the three months ended March 31, 2018 and 2017, respectively, is as follows (in thousands):

The remaining restructuring and other accruals are expected to be paid or extinguished during the next twelve months and are all classified as current liabilities within Other accrued expenses in the Consolidated Balance Sheets.

Integration Charges

During the third and fourth quarters of 2017, as a result of the Connextions acquisition, certain integration activities were completed and $5.6 million and $3.9 million of additional expenses were incurred and paid, respectively. These integration activities included the hiring, training and licensing of a group of employees at new delivery centers as one of the acquired centers was closed during the third quarter of 2017 and one of the acquired centers was closed during the fourth quarter of 2017. In connection with these center closures, leasehold improvements of $3.5 million were written off as a related integration expense. The Company has also incurred significant expenses related to the integration of the IT systems and has paid duplicative software costs and facilities expenses for several areas during the transition period.

Impairment Losses

During each of the periods presented, the Company evaluated the annual recoverability of its leasehold improvement assets at certain customer engagement centers. An asset is considered to be impaired when the anticipated undiscounted future cash flows of its asset group are estimated to be less than the asset group’s carrying value. The amount of impairment recognized is the difference between the carrying value of the asset group and its fair value. To determine fair value, the Company used Level 3 inputs in its discounted cash flows analysis. Assumptions included the amount and timing of estimated future cash flows and assumed discount rates. During the three months ended March 31, 2018 and 2017, the Company recognized impairment losses related to leasehold improvement assets of $1.1 million and zero, respectively, in its CMS segment.

COMMITMENTS AND CONTINGENCIES	3 Months Ended
COMMITMENTS AND CONTINGENCIES	Mar. 31, 2018
COMMITMENTS AND CONTINGENCIES [Abstract]
COMMITMENTS AND CONTINGENCIES	(10)COMMITMENTS AND CONTINGENCIES Credit Facility On February 11, 2016, the Company entered into a First Amendment to its June 3, 2013 Amended and Restated Credit Agreement and Amended and Restated Security Agreement (collectively the “Credit Agreement”) for a senior secured revolving credit facility (the “Credit Facility”) with a syndicate of lenders led by Wells Fargo Bank, National Association. The Credit Agreement provides for a secured revolving credit facility that matures on February 11, 2021 with an initial maximum aggregate commitment of $900.0 million, and an accordion feature of up to $1.2 billion in the aggregate, if certain conditions are satisfied. On October 30, 2017, the Company entered into a Third Amendment to the Credit Agreement and exercised the Credit Facility’s accordion feature to increase the total commitment under the Credit Facility to $1.2 billion. All other material terms of the Credit Agreement remained unchanged. Base rate loans bear interest at a rate equal to the greatest of (i) Wells Fargo’s prime rate, (ii) one half of 1% in excess of the federal funds effective rate, and (iii) 1.25% in excess of the one month London Interbank Offered Rate (“LIBOR”); plus in each case a margin of 0% to 0.75% based on the Company’s net leverage ratio. Eurodollar loans bear interest at LIBOR plus a margin of 1.0% to 1.75% based on the Company’s net leverage ratio. Alternate currency loans bear interest at rates applicable to their respective currencies. Letter of credit fees are one eighth of 1% of the stated amount of the letter of credit on the date of issuance, renewal or amendment, plus an annual fee equal to the borrowing margin for Eurodollar loans. The Credit Facility commitment fees are payable to the lenders in an amount equal to the unused portion of the Credit Facility at a rate of 0.125% to 0.250% based on the Company’s net leverage ratio. The Company is obligated to maintain a maximum net leverage ratio no greater than 3.25 to 1.00, and a minimum interest coverage ratio no less than 2.50 to 1.00. The Company primarily utilizes its Credit Agreement to fund working capital, general operations, stock repurchases, dividends and other strategic activities, such as the acquisitions described in Note 2. As of March 31, 2018 and December 31, 2017, the Company had borrowings of $302.5 million and $344.0 million, respectively, under its Credit Agreement, and its average daily utilization was $576.7 million and $410.4 million for the three months ended March 31, 2018 and 2017, respectively. Based on the current level of availability based on the covenant calculations, the Company’s remaining borrowing capacity was approximately $425 million as of March 31, 2018. As of March 31, 2018, the Company was in compliance with all covenants and conditions under its Credit Agreement. Letters of Credit As of March 31, 2018, outstanding letters of credit under the Credit Agreement totaled $3.8 million and primarily guaranteed workers’ compensation and other insurance related obligations. As of March 31, 2018, letters of credit and contract performance guarantees issued outside of the Credit Agreement totaled $1.8 million. Legal Proceedings From time to time, the Company has been involved in legal actions, both as plaintiff and defendant, which arise in the ordinary course of business. The Company accrues for exposures associated with such legal actions to the extent that losses are deemed both probable and reasonably estimable. To the extent specific reserves have not been made for certain legal proceedings, their ultimate outcome, and consequently, an estimate of possible loss, if any, cannot reasonably be determined at this time. Based on currently available information and advice received from counsel, the Company believes that the disposition or ultimate resolution of any current legal proceedings, except as otherwise specifically reserved for in its financial statements, will not have a material adverse effect on the Company’s financial position, cash flows or results of operations.
