3D SYSTEMS CORPORATION
NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
(1) Basis of Presentation
The accompanying unaudited condensed consolidated financial statements include the accounts of 3D Systems Corporation and
all majority-owned subsidiaries and entities in which a controlling interest is maintained (the “Company”). A non-controlling interest in a subsidiary is considered an ownership interest in a majority-owned subsidiary that is not attributable to the parent. The Company includes noncontrolling interests as a component of total equity in the condensed consolidated balance sheets and the net income (loss) attributable to noncontrolling interests are presented as an adjustment from net loss used to arrive at net loss attributable to 3D Systems Corporation in the condensed consolidated statements of operations and comprehensive loss. All significant intercompany transactions and balances have been eliminated in consolidation.
The unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) applicable to interim reports. Accordingly, they do not include all the information and notes required by GAAP for complete financial statements and should be read in conjunction with the audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 (“Form 10-K”).
In the opinion of management, the unaudited condensed consolidated financial statements contain all adjustments, consisting of adjustments of a normal recurring nature, necessary to present fairly the financial position, results of operations and cash flows for the periods presented. The results of operations for the quarter ended March 31, 2018 are not necessarily indicative of the results to be expected for the full year. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results may differ from those estimates and assumptions. Certain prior period amounts presented in the condensed consolidated financial statements and accompanying footnotes have been reclassified to conform to current year presentation. Beginning in 2018, the Company classifies standard product warranty revenue and related expenses within the "Products" line items of the Consolidated Statements of Operations.
All dollar amounts presented in the accompanying footnotes are presented in thousands, except for per share information.
Recently Adopted Accounting Standards
In May 2017, the FASB issued ASU No. 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting” (“ASU 2017-09”), in an effort to reduce diversity and clarify what constitutes a modification, as it relates to the change in terms or conditions of a share-based payment award. According to ASU 2017-09, the Company should account for the effects of a modification unless all of the following are met: (1) the fair value of the modified award is the same as the fair value the original award immediately before the original award is modified, (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified, and (3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments in ASU 2017-09 are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017, with early adoption permitted. The Company adopted ASU 2017-09 beginning January 1, 2018 and the implementation of this guidance did not have a material effect on its consolidated financial statements.
In March 2017, the FASB issued ASU No. 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (“ASU 2017-07”), which standardizes the presentation of net benefit cost in the income statement and on the components eligible for capitalization in assets. ASU 2017-07 is effective for fiscal years beginning after December 15, 2017, including interim periods within those annual periods. The amendments in ASU 2017-07 should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. The Company adopted ASU 2017-07 in the first quarter of 2018 and the implementation of this guidance did not have a material effect on its consolidated financial statements.
On January 1, 2018, the Company adopted ASC Topic 606, “Revenue from Contracts with Customers.” The standard outlines a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied. The standard also requires new, expanded disclosures regarding revenue recognition. The Company adopted the standard using the modified
8

retrospective transition method and applied its guidance to contracts not completed at the adoption date. The cumulative effect of initial adoption was recorded as a $576 decrease to the January 1, 2018 opening Accumulated Deficit balance and driven primarily by the timing of recognition related to marketing incentives. The effect of this adoption was immaterial to the Consolidated Financial Statements, and the Company does not expect a material effect to its Consolidated Financial Statements on an ongoing basis. Information for comparative periods has not been restated and continues to be reported under the previously applicable revenue accounting guidance ("ASC 605"). Had ASC 605 been applied to the first quarter of 2018, the Consolidated Statements of Operations and Comprehensive Loss would have shown increased Revenue and a decrease in Net Loss Attributable to 3D Systems Corporation of $46. On Consolidated Balance Sheets, Other Assets would have been $457 lower, Deferred Revenues would have been $73 higher and the Accumulated deficit would have increased by $530.
Accounting Standards Issued But Not Yet Adopted
In February 2018, the FASB issued ASU No. 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" (ASU 2018-02), which provides companies with an option to reclassify stranded tax effects resulting from the U.S. Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. ASU 2018-02 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. The Company is currently in the process of evaluating when it will adopt ASU 2018-02 and its impact on its consolidated financial statements.
In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”), in order to create more transparency around how economic results are presented within both the financial statements and in the footnotes and to better align the results of cash flow and fair value hedge accounting with risk management activities. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company is currently in the process of evaluating when it will adopt ASU 2017-12 and its impact on its consolidated financial statements.
In January 2017, the FASB issued ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”), which eliminates the performance of Step 2 from the goodwill impairment test. In performing its annual or interim impairment testing, an entity will instead compare the fair value of the reporting unit with its carrying amount and recognize any impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss. The standard is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual impairment tests performed on testing dates after January 1, 2017. The Company is currently in the process of evaluating when it will adopt ASU 2017-04 and its impact on its consolidated financial statements.
In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). ASU 2016-02 requires lessees to recognize assets and liabilities on the balance sheet for all leases with terms longer than twelve months. The ASU also requires disclosure of key information about leasing arrangements. ASU 2016-02 is effective on January 1, 2019, using a modified retrospective method of adoption as of January 1, 2017. In January 2018, the FASB issued an exposure draft of the proposed ASU, Leases (Topic 842): Targeted Improvements. The proposed ASU provides an alternative transition method of adoption, permitting the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption. The Company will adopt the standard on the effective date, but has not yet selected a transition method. The Company is reviewing its population of leased assets to determine potential impacts on its consolidated financial statements. Though its evaluation is ongoing, the Company expects changes to its balance sheet due to the recognition of right-of-use assets and lease liabilities related to its real estate leases, but it does not anticipate material impacts to its results of operations or liquidity.
No other new accounting pronouncements, issued or effective during 2018, have had or are expected to have a significant impact on the Company’s consolidated financial statements.
(2) Revenue
The Company accounts for revenue in accordance with ASC Topic 606, “Revenue from Contracts with Customers,” which it adopted on January 1, 2018, using the modified-retrospective method. See Note 1 for further discussion of the adoption.

Performance Obligations
A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC Topic 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied.
At March 31, 2018, the Company had $157,531 of outstanding performance obligations. The Company expects to recognize approximately 95 percent of its remaining performance obligations as revenue within the next twelve months, an additional 3 percent by the end of 2019 and the balance thereafter.
Revenue Recognition
Revenue is recognized when control of the promised products or services is transferred to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. The Company enters into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. Many of its contracts with customers include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price (“SSP”). Revenue is recognized net of allowances for returns and any taxes collected from customers, which are subsequently remitted to governmental authorities. The amount of consideration we receive and revenue we recognize varies with changes in marketing incentives we offer to our customers. Our marketing incentives take many forms, including volume discounts, trade-in allowances, rebates and other discounts.
A majority of the Company’s revenue is recognized at the point in time when products are shipped or or services are delivered to customers. Please see below for further discussion.
Systems and Materials
Revenue from systems and material sales is recognized when control has transferred to the customer which typically occurs when the goods have been shipped to the customer, risk of loss has transferred to the customer and the company has a present right to payment for the hardware. In limited circumstances when a systems sale includes substantive customer acceptance provisions, revenue is recognized either when customer acceptance has been obtained, customer acceptance provisions have lapsed, or the company has objective evidence that the criteria specified in the customer acceptance provisions have been satisfied.
Software
The Company also markets and sells software tools that enable our customers to capture and customize content using our printers, as well as reverse engineering and inspection software. These software licenses do not require significant modification or customization and provide the customer with a right to use the software as it exists when made available. Revenue from these software licenses is recognized either upon delivery of the product or of a key code which allows the customer to download the software. Customers may purchase post sale support. Generally, the first year is included but subsequent years are optional. This optional support is considered a separate obligation from the software and is deferred at the time of sale and subsequently recognized ratably over future periods.
Services
The Company offers training, installation and non-contract maintenance services for its products. Additionally, the Company offers extended warranties and maintenance contracts customers can purchase at their option. For optional warranty or maintenance contracts, revenue is deferred at the time of sale based on the stand-alone selling prices of these services and costs are expensed as incurred. Deferred revenue is recognized ratably over the term of the warranty or maintenance period on a straight-line basis. Revenue from training, installation and non-contract maintenance services is recognized at the time of performance of the service.
On demand manufacturing and healthcare service sales are included within services revenue and revenue is recognized upon shipment or delivery of the parts or performance of the service, based on the terms of the arrangement.
Terms of sale
Shipping and handling activities are treated as fulfillment costs rather than as an additional promised service. The Company accrues the costs of shipping and handling when the related revenue is recognized. Costs incurred by the Company associated with shipping and handling are included in product cost of sales.
10

Credit is extended, and creditworthiness is determined, based on an evaluation of each customer’s financial condition. New customers are generally required to complete a credit application and provide references and bank information to facilitate an analysis of creditworthiness. Customers with a favorable profile may receive credit terms that differ from the Company’s general credit terms. Creditworthiness is considered, among other things, in evaluating the Company’s relationship with customers with past due balances.
The Company’s terms of sale generally require payment within 30 to 60 days after shipment of a product, although the Company also recognizes that longer payment periods are customary in some countries where it transacts business. To reduce credit risk in connection with printer sales, the Company may, depending upon the circumstances, require significant deposits prior to shipment and may retain a security interest in a system sold until fully paid. In some circumstances, the Company may require payment in full for its products prior to shipment and may require international customers to furnish letters of credit. For maintenance services, the Company either bills customers on a time-and-materials basis or sells maintenance contracts that provide for payment in advance on either an annual or other periodic basis.
See Note 12 for additional information related to revenue by reportable segment and major lines of business.
Significant Judgments
The Company’s contracts with customers often include promises to transfer multiple products and services to a customer. For such arrangements, the Company allocates revenues to each performance obligation based on its relative SSP.
Judgment is required to determine the SSP for each distinct performance obligation in a contract. For the majority of items, the Company estimates SSP using historical transaction data. The Company uses a range of amounts to estimate SSP when we sell each of the products and services separately and need to determine whether there is a discount to be allocated based on the relative SSP of the various products and services. In instances where SSP is not directly observable, such as when the product or service are not sold separately, the Company determines the SSP using information that may include market conditions and other observable inputs.
In some circumstances, the Company has more than one SSP for individual products and services due to the stratification of those products and services by customers, geographic region or other factors. In these instances, it may use information such as the size of the customer and geographic region in determining the SSP.
The determination of SSP is in ongoing process and information is reviewed regularly in order to ensure SSPs reflect the most current information or trends.
Often, the nature of the Company’s marketing incentives lead to consideration that is variable. Judgment is exercised at contract inception to determine the most likely outcome of the contract and resulting transaction price. Ongoing assessments are performed to determine if updates are needed to the original estimates
Contract Balances
The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer deposits and deferred revenues (contract liabilities) on the Consolidated Balance Sheets. Timing of revenue recognition may differ from the timing of invoicing to customers. The Company records a receivable when revenue is recognized at the time of invoicing, or unbilled receivables when revenue is recognized prior to invoicing. For most of the Company’s contracts, customers are invoiced when products are shipped or when services are performed resulting in billed accounts receivables where payment is generally required within 30 to 60 days. Unbilled receivables generally result from items being shipped where the customer has not been charged but for which revenue had been recognized. In the Company’s on-demand manufacturing business, customers may be required to pay in full before work begins on their orders, resulting in customer deposits. The Company typically bills in advance for installation, training and maintenance contracts as well as extended warranties, resulting in deferred revenue. Changes in contract asset and liability balances were not materially impacted by any other factors for the period ended March 31, 2018.
In the first quarter of 2018, we recognized revenue of $15,318 related to our contract liabilities at January 1, 2018.

Practical Expedients and Exemptions
The Company generally expenses sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling, general and administrative expenses.

Total | $ | 46,665 |  |  | $ | 48,754 |

(6) Hedging Activities and Financial Instruments
The Company conducts business in various countries using both the functional currencies of those countries and other currencies to effect cross border transactions. As a result, the Company is subject to the risk that fluctuations in foreign exchange rates between the dates that those transactions are entered into and their respective settlement dates will result in a foreign exchange gain or loss. When practicable, the Company endeavors to match assets and liabilities in the same currency on its balance sheet and those of its subsidiaries in order to reduce these risks. When appropriate, the Company enters into foreign currency contracts to hedge exposures arising from those transactions. The Company has elected not to prepare and maintain the documentation to qualify for hedge accounting treatment under Accounting Standards Codification (“ASC”) 815, “Derivatives and Hedging,” and therefore, all gains and losses (realized or unrealized) are recognized in “Interest and other expense, net” in the condensed consolidated statements of operations and comprehensive loss. Depending on their fair value at the end of the reporting period, derivatives are recorded either in prepaid expenses and other current assets or in accrued liabilities on the condensed consolidated balance sheet.
The Company had $40,752 and $39,600 in notional foreign exchange contracts outstanding as of March 31, 2018 and December 31, 2017, respectively. The fair values of these contracts were not material.
The Company translates foreign currency balance sheets from each international businesses' functional currency (generally the respective local currency) to U.S. dollars at end-of-period exchange rates, and statements of earnings at average exchange rates for each period. The resulting foreign currency translation adjustments are a component of other comprehensive income (loss).
The Company does not hedge the fluctuation in reported revenue and earnings resulting from the translation of these international operations' results into U.S. dollars. The impact of translating the Company’s non-U.S. operations’ revenue and earnings into U.S. dollars was not material to the Company’s results of operations for the quarters ended March 31, 2018 and 2017.
13

(7) Borrowings
Credit Facility
As of March 31, 2018, the Company had a $150,000 revolving, unsecured credit facility (the “Credit Agreement”) with a syndicate of banks, to be used for general corporate purposes and working capital needs. The Credit Agreement is scheduled to expire in October 2019. The Credit Agreement includes provisions for the issuance of letters of credit and swingline loans and contains certain restrictive covenants, which include the maintenance of a maximum consolidated total leverage ratio. The Company was in compliance with those covenants at March 31, 2018 and December 31, 2017. There were no outstanding borrowings as of March 31, 2018.
Capitalized Lease Obligations
The Company’s capitalized lease obligations primarily include a lease agreement that was entered into during 2006 with respect to the Company’s corporate headquarters located in Rock Hill, SC. The change in capitalized lease obligations, as presented in the Condensed Consolidated Balance Sheets, was due to the normal scheduled timing of payments.
(8) Pension Benefits
The components of the Company’s pension cost recognized in the condensed consolidated statements of operations and comprehensive loss for the quarters ended March 31, 2018 and 2017 were as follows:

﻿ | Quarter Ended March 31,
(in thousands) | 2018 |  | 2017
Service cost | $ | 52 |  |  | $ | 67 |
Interest cost | 73 |  |  | 65 |
Amortization of actuarial loss | 46 |  |  | 58 |
Total periodic cost | $ | 171 |  |  | $ | 190 |

(9) Net Loss Per Share
The Company computes basic loss per share using net loss attributable to 3D Systems Corporation and the weighted average number of common shares outstanding during the applicable period. Diluted loss per share incorporates the additional shares issuable upon assumed exercise of stock options and the release of restricted stock and restricted stock units, except in such case when their inclusion would be anti-dilutive.

﻿ | Quarter Ended March 31,
(in thousands, except per share amounts) | 2018 |  | 2017
Numerator for basic and diluted net loss per share: |  |  |
Net loss attributable to 3D Systems Corporation | $ | (20,961 | ) |  | $ | (9,971 | )
Denominator for basic and diluted net loss per share: |  |  |
Weighted average shares | 111,819 |  |  | 111,289 |
Net loss per share - basic and diluted | $ | (0.19 | ) |  | $ | (0.09 | )

For the quarters ended March 31, 2018 and 2017, the effect of dilutive securities, including non-vested stock options and restricted stock awards/units, was excluded from the denominator for the calculation of diluted net loss per share because the Company recognized a net loss for the period and their inclusion would be anti-dilutive. Dilutive securities excluded were 4,345 and 3,396 for the quarters ended March 31, 2018 and 2017, respectively.

(10) Fair Value Measurements
ASC 820, “Fair Value Measurements and Disclosures,” defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs that may be used to measure fair value:
Level 1 - Quoted prices in active markets for identical assets or liabilities;
Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; or
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.
For the Company, the above standard applies to cash equivalents and earnout consideration. The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.
Assets and liabilities measured at fair value on a recurring basis are summarized below:

| Fair Value Measurements as of March 31, 2018
(in thousands) | Level 1 |  | Level 2 |  | Level 3 |  | Total
Description |  |  |  |  |  |  |
Cash equivalents (a) | $ | 40,891 |  |  | $ | — |  |  | $ | — |  |  | $ | 40,891 |
Earnout consideration (b) | $ | — |  |  | $ | — |  |  | $ | 2,556 |  |  | $ | 2,556 |
﻿ |  |  |  |  |  |  |
| Fair Value Measurements as of December 31, 2017
(in thousands) | Level 1 |  | Level 2 |  | Level 3 |  | Total
Description |  |  |  |  |  |  |
Cash equivalents (a) | $ | 20,244 |  |  | $ | — |  |  | $ | — |  |  | $ | 20,244 |
Earnout consideration (b) | $ | — |  |  | $ | — |  |  | $ | 5,115 |  |  | $ | 5,115 |

(a) | Cash equivalents include funds held in money market instruments and are reported at their current carrying value, which approximates fair value due to the short-term nature of these instruments and are included in cash and cash equivalents in the consolidated balance sheet.

(b) | The fair value of the earnout consideration, which is based on the present value of the expected future payments to be made to the sellers of the acquired businesses, was derived by analyzing the future performance of the acquired businesses using the earnout formula and performance targets specified in each purchase agreement and adjusting those amounts to reflect the ability of the acquired entities to achieve the stated targets. Given the significance of the unobservable inputs, the valuations are classified in Level 3 of the fair value hierarchy. The change in earnout consideration reflects a $2,675 payment, partially offset by $115 of accretion.

The Company did not have any transfers of assets and liabilities between Level 1, Level 2 and Level 3 of the fair value measurement hierarchy during the quarter ended March 31, 2018.
In addition to the assets and liabilities included in the above table, certain of our assets and liabilities are to be initially measured at fair value on a non-recurring basis. This includes goodwill and other intangible assets measured at fair value for impairment assessment, in addition to redeemable noncontrolling interests. For additional discussion, refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Significant Estimates” in the Company’s Form 10-K.

(11) Income Taxes
For the quarters ended March 31, 2018 and 2017, the Company recorded expense of $1,954 and $1,041, respectively, resulting in effective tax rates of 10.3% and 11.7%, respectively. The difference between the statutory rate and the effective tax rate is driven from the impact of the change in valuation allowances that the Company has recorded in the US and other foreign jurisdictions for both quarters ended March 31, 2018 and 2017.
In December 2017, the Tax Cuts and Jobs Act of 2017 (the “Act”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings, as of December 31, 2017.
On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. As of December 31, 2017, the Company recorded provisional amounts, and additional work is still necessary for a more detailed analysis of the Company’s deferred tax assets and liabilities and its historical foreign earnings as well as potential correlative adjustments. Any subsequent adjustment to these amounts will be recorded in the quarter of 2018 when the analysis is complete.
As the Company’s previously unremitted earnings have now been subjected to U.S. federal income tax, any repatriation of these earnings to the U.S. would not be expected to incur significant additional taxes related to such amounts.
Tax years 2003 through 2017 remain subject to examination by the U.S. Internal Revenue Service, with most of the years open to examination due to the generation and utilization of various tax credits. The Company files income tax returns (which are open to examination beginning in the year shown in parentheses) in Australia (2013), Belgium (2014), Brazil (2012), China (2014), France (2014), Germany (2013), India (2013), Israel (2013), Italy (2012), Japan (2012), Korea (2012), Mexico (2012), Netherlands (2012), Switzerland (2012), the United Kingdom (2016) and Uruguay (2012).
(12) Segment Information
The Company operates as one segment and conducts its business through various offices and facilities located throughout the Americas region (United States, Canada, Brazil, Mexico and Uruguay), EMEA region (Belgium, France, Germany, Israel, Italy, the Netherlands, Switzerland and the United Kingdom), and Asia Pacific region (Australia, China, India, Japan and Korea). The Company has historically disclosed summarized financial information for the geographic areas of operations as if they were segments in accordance with ASC 280, “Segment Reporting.” Financial information concerning the Company’s geographical locations is based on the location of the selling entity. Such summarized financial information concerning the Company’s geographical operations is shown in the following tables:

(13) Commitments and Contingencies
The Company leases certain of its facilities and equipment under non-cancelable operating leases. For the quarters ended March 31, 2018 and 2017, rent expense under operating leases was $4,267 and $3,682, respectively.
Certain of the Company’s acquisition agreements contain earnout provisions under which the sellers of the acquired businesses can earn additional amounts. The total liability recorded for these earnouts at March 31, 2018 and December 31, 2017 was $2,556 and $5,115, respectively. See Note 5.
Put Options
Owners of interests in a certain subsidiary have the right in certain circumstances to require the Company to acquire either a portion of or all of the remaining ownership interests held by them. The owners’ ability to exercise any such “put option” right is subject to the satisfaction of certain conditions, including conditions requiring notice in advance of exercise. In addition, these rights cannot be exercised prior to a specified exercise date. The exercise of these rights at their earliest contractual date would result in obligations of the Company to fund the related amounts in 2019.
Management estimates, assuming that the subsidiary owned by the Company at March 31, 2018, performs over the relevant future periods at its forecasted earnings levels, that these rights, if exercised, could require the Company, in future periods, to pay approximately $8,872 to the owners of such rights to acquire such ownership interests in the relevant subsidiary. This amount has been recorded as redeemable noncontrolling interests on the Consolidated Balance Sheet at March 31, 2018 and December 31, 2017. The ultimate amount payable relating to this transaction will vary because it is dependent on the future results of operations of the subject business.

Litigation
Securities and Derivative Litigation
The Company and certain of its former executive officers have been named as defendants in a consolidated putative stockholder class action lawsuit pending in the United States District Court for the District of South Carolina. The consolidated action is styled KBC Asset Management NV v. 3D Systems Corporation, et al., Case No. 0:15-cv-02393-MGL. The Amended Consolidated Complaint (the “Complaint”), which was filed on December 9, 2015, alleges that defendants violated the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 10b-5 promulgated thereunder by making false and misleading statements and omissions and that the former officers are control persons under Section 20(a) of the Exchange Act. The Complaint was filed on behalf of stockholders who purchased shares of the Company’s common stock between October 29, 2013, and May 5, 2015 and seeks monetary damages on behalf of the purported class. Defendants filed a motion to dismiss the Complaint in its entirety on January 14, 2016, which was denied by Memorandum Opinion and Order dated July 25, 2016 (the “Order”). Defendants filed a motion for reconsideration of the Order on August 4, 2016, which was denied by Order dated February 24, 2017. On September 28, 2017, the Court granted Lead Plaintiff’s Motion for Class Certification. On February 14, 2018, following mediation, the parties entered into a Stipulation of Settlement that provides for, among other things, payment of $50 million by the Company’s insurance carriers and a mutual exchange of releases. The Stipulation of Settlement calls for a dismissal of all claims against the Company and the individual defendants with prejudice following Court approval, a denial by defendants of any wrongdoing, and no admission of liability. On February 15, 2018, Lead Plaintiff filed an Unopposed Motion for Preliminary Approval of Class Action Settlement. On February 21, 2018, the Court entered an Order Preliminarily Approving Settlement and Providing for Notice. The final approval hearing has been scheduled for June 25, 2018. A current liability of $50,000 was recorded for the agreed upon settlement amount and an offsetting receivable of $50,000 was recorded for related insurance proceeds.
Nine related derivative complaints have been filed by purported Company stockholders against certain of the Company’s former executive officers and members of its Board of Directors. The Company is named as a nominal defendant in all nine actions. The derivative complaints are styled as follows: (1) Steyn v. Reichental, et al., Case No. 2015-CP-46-2225, filed on July 27, 2015 in the Court of Common Pleas for the 16th Judicial Circuit, County of York, South Carolina (“Steyn”); (2) Piguing v. Reichental, et al., Case No. 2015-CP-46-2396, filed on August 7, 2015 in the Court of Common Pleas for the 16th Judicial Circuit, County of York, South Carolina (“Piguing”); (3) Booth v. Reichental, et al., Case No. 15-692-RGA, filed on August 6, 2015 in the United States District Court for the District of Delaware; (4) Nally v.

Reichental, et al., Case No. 0:16-cv-02995-MGL, filed on September 1, 2016 in the United States District Court for the District of South Carolina (“Ameduri”). Steyn and Piguing were consolidated into one action styled as In re 3D Systems Corp. Shareholder Derivative Litig., Lead Case No. 2015-CP-46-2225 in the Court of Common Pleas for the 16th Judicial Circuit, County of York, South Carolina. Gee and Lu were consolidated into one action styled as Gee v. Hull, et al., Case No. BC610319 in the Superior Court for the State of California, County of Los Angeles. Nally, Foster, Howes, and Ameduri were consolidated into one action in the United States District Court for the District of South Carolina with Nally as the lead consolidated case.
The derivative complaints allege claims for breach of fiduciary duty, abuse of control, gross mismanagement, waste of corporate assets and unjust enrichment and seek, among other things, monetary damages and certain corporate governance actions.
All of the derivative complaints listed above have been stayed until the earlier of the close of discovery or the deadline for appealing a dismissal in the KBC Asset Management NV securities class action.
The Company believes the claims alleged in the derivative lawsuits are without merit and intends to defend the Company and its officers and directors vigorously.
Ronald Barranco and Print3D Corporation v. 3D Systems Corporation, et. al.
On August 23, 2013, Ronald Barranco, a former Company employee, filed two lawsuits against the Company and certain officers in the United States District Court for the District of Hawaii. The first lawsuit (“Barranco I”) is captioned Ronald Barranco and Print3D Corporation v. 3D Systems Corporation, 3D Systems, Inc., and Damon Gregoire, Case No. CV 13-411 LEK RLP, and alleges seven causes of action relating to the Company’s acquisition of Print3D Corporation (of which Mr. Barranco was a 50% shareholder) and the subsequent employment of Mr. Barranco by the Company. The second lawsuit (“Barranco II”) is captioned
18

Ronald Barranco v. 3D Systems Corporation, 3D Systems, Inc., Abraham Reichental, and Damon Gregoire, Case No. CV 13-412 LEK RLP, and alleges the same seven causes of action relating to the Company’s acquisition of certain website domains from Mr. Barranco and the subsequent employment of Mr. Barranco by the Company. Both Barranco I and Barranco II allege the Company breached certain purchase agreements in order to avoid paying Mr. Barranco additional monies pursuant to royalty and earn out provisions in the agreements. The Company and its officers timely filed responsive pleadings on October 22, 2013 seeking, inter alia, to dismiss Barranco I due to a mandatory arbitration agreement and for lack of personal jurisdiction and to dismiss Barranco II for lack of personal jurisdiction.
With regard to Barranco I, the Hawaii district court, on February 28, 2014, denied the Company’s motion to dismiss and its motion to transfer venue to South Carolina for the convenience of the parties. However, the Hawaii court recognized that the plaintiff’s claims are all subject to mandatory and binding arbitration in Charlotte, North Carolina. Because the Hawaii court was without authority to compel arbitration outside of Hawaii, the court ordered that the case be transferred to the district court encompassing Charlotte (the United States District Court for the Western District of North Carolina) so that court could compel arbitration in Charlotte. On April 17, 2014, Barranco I was transferred to the United States District Court for the Western District of North Carolina. Plaintiff filed a demand for arbitration on October 29, 2014. On December 9, 2014, the Company filed its answer to plaintiff’s demand for arbitration. On February 2, 2015, plaintiff filed an amended demand that removed Mr. Gregoire as a defendant from the matter, and on February 4, 2015 the Company filed its amended answer. The parties selected an arbitrator and arbitration took place in September 2015 in Charlotte, North Carolina.
On September 28, 2015, the arbitrator issued a final award in favor of Mr. Barranco with respect to two alleged breaches of contract and implied covenants arising out of the contract. The arbitrator found that the Company did not commit fraud or make any negligent misrepresentations to Mr. Barranco. Pursuant to the award, the Company is to pay approximately $11,282, which includes alleged actual damages of $7,254, fees and expenses of $2,318 and prejudgment interest of $1,710. The Company disagrees with the single arbitrator’s findings and conclusions and believes the arbitrator’s decision exceeds his authority and disregards the applicable law. As an initial response, the Company filed a motion for modification on September 30, 2015, based on mathematical errors in the computation of damages and fees. On October 16, 2015, the arbitrator issued an order denying the Company’s motion and sua sponte issuing a modified final award in favor of Mr. Barranco in the same above-referenced amounts, but making certain substantive changes to the award, which changes the Company believes were improper and outside the scope of his authority and the American Arbitration Association rules. On November 20, 2015, the Company filed a motion to vacate the arbitration award in the federal court in the United States District Court for the Western District of North Carolina. Claimants also filed a motion to confirm the arbitration award. A hearing was held on the motions on September 29, 2016 in federal court in the Western District of North Carolina. The court requested supplemental briefing by the parties, which briefs were filed on July 11, 2016.
On August 31, 2016, the court issued an order granting in part and denying in part Plaintiff’s motion to confirm the arbitration award and for judgment, entering judgment in the principal amount of the arbitration award and denying Plaintiff’s motion for fees and costs. The court denied the Company’s motion to vacate. On September 7, 2016, Plaintiff filed a motion to amend the judgment to include prejudgment interest. The Company opposed that motion and the parties submitted briefing. On September 28, 2016 the Company filed a motion to alter or amend the judgment. Plaintiff opposed the motion and the parties submitted briefing. On May 18, 2017, the court issued an opinion and order denying the Company’s motion to alter or amend and denying Plaintiff’s motion for prejudgment interest. On September 16, 2017, the Company filed a notice of appeal with the United States Court of Appeals for the Fourth Circuit. The appeal is pending. The Company filed its Opening Brief and the Joint Appendix on August 28, 2017. Plaintiff filed its Opening Brief on September 11, 2017. The Company filed its Reply Brief on September 25, 2017.
Notwithstanding the Company’s right to appeal, given the arbitrator’s decision, the Company recorded an $11,282 expense provision for this matter in the quarter ended September 30, 2015. The provision is subject to adjustment based on the ultimate outcome of the Company’s appeal. If it is ultimately determined that money is owed following the full appellate process in federal court, the Company intends to fund any amounts to be paid from cash on hand. This amount has been classified as a current liability given the timeline of the appeals process.
With regard to Barranco II, the Hawaii district court, on March 17, 2014, denied the Company’s motion to dismiss and its motion to transfer venue to South Carolina. However, the Hawaii court dismissed Count II in plaintiff’s complaint alleging breach of the employment agreement. The Company filed an answer to the complaint in the Hawaii district court on March 31, 2014. On November 19, 2014, the Company filed a motion for summary judgment on all claims which was heard on January 20, 2015. On January 30, 2015, the court entered an order granting in part and denying in part the Company’s motion for summary judgment. The Order narrowed the plaintiff’s claim for breach of contract and dismissed the plaintiff’s claims for fraud and negligent misrepresentation. As a result, Messrs. Reichental and Gregoire were dismissed from the lawsuit. The case was tried to a jury in May 2016, and on May 27, 2016 the jury found that the Company was not liable for either breach of contract or breach of the implied covenant of good faith and fair dealing. Additionally, the jury found in favor of the Company on its counterclaim against
19

Mr. Barranco and determined that Mr. Barranco violated his non-competition covenant with the Company. On July 5, 2017, the court ordered a bench trial regarding causation and damages with respect to the equitable accounting on the Company’s prevailing counterclaim against Mr. Barranco. The bench trial took place on November 20, 2017. The court ordered the submission of proposed findings of fact and conclusions of law. The Company submitted its proposed Findings of Fact and Conclusions of Law on January 12, 2018. Barranco submitted his on February 2, 2018. The Company submitted its Reply on February 16, 2018. On March 30, 2018, the court entered Findings of Fact and Conclusions of Law and Order requiring Barranco to disgorge, and the Company to recover, $522.9, representing all but four months of the full amount paid to Barranco as salary during his employment with the Company as well as a portion of the up front and buyout payments made to Barranco in connection with the purchase of certain web domains. In addition, the Court ordered Barranco to pay pre-judgment interest to the Company to be calculated beginning as of his first breach of the non-competition covenant in August 2011. Judgment entered thereafter on April 2, 2018. As the prevailing party, the Company has moved for recovery of its fees and costs. The motion is pending before the court. On April 19, 2018, Barranco filed a post-trial motion seeking to amend the findings and judgment. The Company will oppose that motion.
Export Compliance Matter
In October 2017 the Company received an administrative subpoena from the Bureau of Industry and Security of the Department of Commerce (“BIS”) requesting the production of records in connection with possible violations of U.S. export control laws, including with regard to its Quickparts.com, Inc. subsidiary. In addition, while collecting information responsive to the above-referenced subpoena, the Company identified potential violations of the International Traffic in Arms Regulations (“ITAR”) administered by the Directorate of Defense Trade Controls of the Department of State (“DDTC”) and potential violations of the Export Administration Regulations administered by the Bureau of Industry and Security of the Department of Commerce. On February 12, 2018, the Company submitted an initial notice of voluntary disclosure to DDTC in which the Company identified certain potentially unauthorized exports of technical data. The Company is continuing to conduct an internal review and cooperating fully with the investigation, but cannot predict the ultimate resolution of this matter. The Company expects to incur significant legal costs and other expenses in connection with responding to these inquiries.
If the U.S. government finds that the Company has violated one or more export control laws or trade sanctions, the Company could be subject to various penalties. By statute, these penalties can include but are not limited to fines, which by statute may be significant, denial of export privileges, and debarment from participation in U.S. government contracts; and any assessment of penalties could also harm the Company’s reputation, create negative investor sentiment, and affect the Company’s share value. In connection with any resolution, the Company may also be required to undertake additional remedial compliance measures and program monitoring. The Company cannot at this time predict when BIS and/or DDTC will conclude their investigations or determine an estimated cost, if any, or range of costs, for any penalties or fines that may be incurred upon resolution of this matter.
Indemnification
In the normal course of business, the Company periodically enters into agreements to indemnify customers or suppliers against claims of intellectual property infringement made by third parties arising from the use of the Company’s products. Historically, costs related to these indemnification provisions have not been significant, and the Company is unable to estimate the maximum potential impact of these indemnification provisions on its future results of operations.
To the extent permitted under Delaware law, the Company indemnifies its directors and officers for certain events or occurrences while the director or officer is, or was, serving at the Company’s request in such capacity, subject to limited exceptions. The maximum potential amount of future payments the Company could be required to make under these indemnification obligations is unlimited; however, the Company has directors and officers insurance coverage that may enable the Company to recover future amounts paid, subject to a deductible and the policy limits. There is no assurance that the policy limits will be sufficient to cover all damages, if any.

Results of Operations
Comparison of revenue by geographic region
The following table sets forth the change in revenue by geographic region for the quarters ended March 31, 2018 and 2017.
Table 1

(Dollars in thousands) | Americas |  | EMEA |  | Asia Pacific |  | Total
Revenue — first quarter 2017 | $ | 80,291 |  |  | 51.3 | % |  | $ | 52,958 |  |  | 33.9 | % |  | $ | 23,182 |  |  | 14.8 | % |  | $ | 156,431 |  |  | 100.0 | %
Change in revenue: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Volume | 6,631 |  |  | 8.3 | % |  | (511 | ) |  | (1.0 | )% |  | 873 |  |  | 3.8 | % |  | 6,993 |  |  | 4.5 | %
Price/Mix | (2,386 | ) |  | (3.0 | )% |  | (1,949 | ) |  | (3.7 | )% |  | (1,402 | ) |  | (6.0 | )% |  | (5,737 | ) |  | (3.7 | )%

Net change | 4,256 |  |  | 5.3 | % |  | 4,458 |  |  | 8.4 | % |  | 743 |  |  | 3.3 | % |  | 9,457 |  |  | 6.0 | %
Revenue — first quarter 2018 | $ | 84,547 |  |  | 51.0 | % |  | $ | 57,416 |  |  | 34.6 | % |  | $ | 23,925 |  |  | 14.4 | % |  | $ | 165,888 |  |  | 100.0 | %

Consolidated revenue increased 6.0%, predominantly driven by higher sales volumes in the Americas and APAC regions and the favorable impact of foreign currency in the EMEA and APAC regions, offset by a shift in product mix and average selling price across all geographic regions. The increase in sales volume is due to demand from healthcare and industrial customers. The shift in product mix and average selling price across all geographic regions relates to sales of printer models which carry lower price points.
For the quarters ended March 31, 2018 and 2017, revenue from operations outside the U.S., including Latin America, EMEA and APAC, was 50.1% and 50.2% of total revenue, respectively.
Comparison of revenue by class
We earn revenue from the sale of products, materials and services. The products category includes 3D printers, healthcare simulators and digitizers, software licenses, 3D scanners and haptic devices. The materials category includes a wide range of materials to be used with our 3D printers, the majority of which are proprietary, as well as acquired conventional dental materials. The services category includes maintenance contracts and services on 3D printers and simulators, software maintenance, on demand manufacturing solutions and healthcare services. Beginning in 2018, we have classified product warranty revenue and related expenses within products and we have reclassified prior period amounts from services to products to conform to current year presentation.
Due to the relatively high price of certain 3D printers and a corresponding lengthy selling cycle and relatively low unit volume of the higher priced printers in any particular period, a shift in the timing and concentration of orders and shipments from one period to another can affect reported revenue in any given period. Revenue reported in any particular period is also affected by timing of revenue recognition under rules prescribed by U.S. generally accepted accounting principles (“GAAP”).
In addition to changes in sales volumes and the impact of revenue from acquisitions, there are two other primary drivers of changes in revenue from one period to another: (1) the combined effect of changes in product mix and average selling prices, sometimes referred to as price and mix effects, and (2) the impact of fluctuations in foreign currencies. As used in this Management’s Discussion and Analysis, the price and mix effects relate to changes in revenue that are not able to be specifically related to changes in unit volume.

Net change | 8,413 |  |  | 15.6 | % |  | (327 | ) |  | (0.7 | )% |  | 1,371 |  |  | 2.3 | % |  | 9,457 |  |  | 6.0 | %
Revenue — first quarter 2018 | $ | 62,629 |  |  | 37.8 | % |  | $ | 42,496 |  |  | 25.6 | % |  | $ | 60,763 |  |  | 36.6 | % |  | $ | 165,888 |  |  | 100.0 | %

Consolidated revenue increased 6.0%, predominantly driven by products revenue and the favorable impact of foreign currency translation, partially offset by a shift in product mix which impacted average selling price for both products and materials.
Products revenue increased due to higher demand from healthcare and industrial customers as well as the favorable impact of foreign currency, offset by changes in product mix which impacted average selling prices from the shift to higher sales of lower priced printers. For the quarters ended March 31, 2018 and 2017, revenue from printers contributed $39.1 million and $31.4 million, respectively. Software revenue included in the products category, including scanners and haptic devices, contributed $12.3 million and $9.8 million for the quarters ended March 31, 2018 and 2017, respectively.
Materials revenue remained relatively flat as the favorable impact of foreign currency was offset by changes in product mix and average selling prices.
Services revenue increased due to the favorable impact of foreign currency translation, partially offset by lower sales volume. For the quarters ended March 31, 2018 and 2017, revenue from on demand manufacturing services contributed $25.7 million and $25.1 million, respectively. For the quarters ended March 31, 2018 and 2017, software services revenue contributed $10.8 million and $10.6 million, respectively.

The decrease in total consolidated gross profit is due to mix of sales, particularly in printers, and higher costs in on demand manufacturing.
On demand manufacturing services gross profit margin decreased to 38.8% for the quarter ended March 31, 2018 compared to 43.3% for the quarter ended March 31, 2017.

Total operating expenses increased for the quarter ended March 31, 2018 as compared to the quarter ended March 31, 2017 due to both increased selling, general and administrative expenses and research and development expenses. The increase in selling, general and administrative expenses is primarily due to increased marketing and advertising, the implementation of a market-based job architecture and higher bad debt expense and legal expenses. Research and development expenses increased primarily in support of the new products we plan to bring to market throughout 2018 and focused innovation to drive customers’ shift to 3D production, including investment in plastics, metals, materials and software as well as the addition of talent and resources.
Loss from operations
The following table sets forth loss from operations by geographic region for the quarters ended March 31, 2018 and 2017.

The increase in operating loss for the quarter ended March 31, 2018 compared to the quarter ended March 31, 2017 was primarily driven by a decrease in gross profit and an increase in operating expenses. See “Comparison of revenue by geographic region,” “Gross profit and gross profit margins” and “Operating expenses” above.

Operating working capital | $ | 243,952 |  |  | $ | 247,976 |  |  | $ | (4,024 | ) |  | (1.6 | )%

We assess our liquidity in terms of our ability to generate cash to fund our operating, investing and financing activities. In doing so, we review and analyze our current cash on hand, the number of days our sales are outstanding, inventory turns, capital expenditure commitments and accounts payable turns. Our cash requirements primarily consist of funding of working capital and funding of capital expenditures.
We believe our existing cash and cash equivalents will be sufficient to satisfy our working capital needs, capital expenditures, outstanding commitments and other liquidity requirements associated with our existing operations in the foreseeable future, or to consummate significant acquisitions of other businesses, assets, products or technologies. However, it is possible that, in the future, we may need to raise additional funds to finance our activities. If needed, we may be able to raise such funds by issuing equity or debt securities to the public or selected investors, by borrowing from financial institutions, drawing down on our credit facility, or selling assets.
Cash held outside the U.S. at March 31, 2018 was $89.4 million, or 73.6% of total cash and equivalents, compared to $88.9 million, or 65.2% of total cash and equivalents at December 31, 2017. As our previously unremitted earnings have been subjected to U.S. federal income tax, we expect any repatriation of these earnings to the U.S. would not incur significant additional taxes related to such amounts. However, our estimates are provisional and subject to further analysis. Cash equivalents are comprised of funds held in money market instruments and are reported at their current carrying value, which approximates fair value due to the short term nature of these instruments. We strive to minimize our credit risk by investing primarily in investment grade, liquid instruments and limit exposure to any one issuer depending upon credit quality. See “Cash flow”, “Credit facilities” and “Capitalized lease obligations” below.
Days’ sales outstanding was 72 at March 31, 2018 compared to 73 days at December 31, 2017 while accounts receivable more than 90 days past due increased to 9.4% of gross receivables at March 31, 2018, from 9.1% at December 31, 2017. We review specific receivables periodically to determine the appropriate reserve for accounts receivable.
The majority of our inventory consists of finished goods, including products, materials and service parts. Inventory also consists of raw materials and spare parts for the in-house assembly and support service products. We outsource the assembly of certain 3D printers; therefore, we generally do not hold most parts for the assembly of these printers in inventory.
The changes that make up the other components of working capital not discussed above resulted from the ordinary course of business. Differences between the amounts of working capital item changes in the cash flow statement and the balance sheet changes for the corresponding items are primarily the result of foreign currency translation adjustments.

Cash used in operating activities for the quarter ended March 31, 2018 was $1.5 million and cash generated by operating activities for the quarter ended March 31, 2017 was $19.4 million. Excluding non-cash charges, net income provided cash of $2.9 million for the three months ended March 31, 2018 and $11.3 million for the three months ended March 31, 2017. Non-cash charges generally consist of depreciation, amortization, and stock-based compensation.
Working capital requirements used cash of $4.4 million for the quarter ended March 31, 2018 and provided $8.1 million for the quarter ended March 31, 2017. In the quarter ended March 31, 2018, cash outflows resulting from increases in accounts receivable, inventory and other current assets were partially offset by an increase in deferred revenues. In the quarter ended March 31, 2017, cash inflows were driven by lower accounts receivable balances combined with an increase in deferred revenues and were partially offset by other working capital items.

The primary outflow of cash relates to investments in property, plant and equipment as we invest in infrastructure, add to our on-demand manufacturing service and equip facilities for new product development efforts. In 2017 we acquired Vertex for an aggregate purchase price of $34.3 million, net of cash acquired.

Cash used in financing activities was $3.6 million and $4.4 million for the quarters ended March 31, 2018 and 2017, respectively. The primary outflows of cash relate to payments on earnout provisions related to one of our acquisitions and the settlement of stock-based compensation.
We may issue additional securities from time to time as necessary to provide flexibility to execute our growth strategy. No securities were issued during the quarter ended March 31, 2018 and 2017.
Contractual commitments and off-balance sheet arrangements
Credit facilities
In October 2014, we entered into a $150.0 million five-year revolving, unsecured credit facility. The agreement provides for advances in the initial aggregate principal amount of up to $150.0 million. Subject to certain terms and conditions contained in the agreement, we may, at our option, request an increase in the aggregate principal amount available under the credit facility by an additional $75.0 million. As of March 31, 2018 and December 31, 2017, there was no outstanding balance on the credit facility. The credit facility contains customary covenants, some of which require us to maintain certain financial ratios that determine the amounts available and terms of borrowings and events of default. We were in compliance with all covenants at both March 31, 2018 and December 31, 2017. See Note 7 to the condensed consolidated financial statements.
Capitalized lease obligations
Our capitalized lease obligations include a lease agreement that we entered into during 2006 with respect to our Rock Hill, SC facility, in addition to other lease agreements assumed through acquisitions. In accordance with ASC 840, “Leases,” we are considered an owner of the properties, therefore, we have recorded these amounts in our consolidated balance sheet with a corresponding capitalized lease obligation in the liabilities section of the consolidated balance sheet. Our outstanding capitalized lease obligations carrying value at March 31, 2018 and December 31, 2017 was $7.6 million and $7.7 million, respectively.
Redeemable noncontrolling interests
The minority interest shareholders of a certain subsidiary have the right to require us to acquire either a portion of or all ownership interest under certain circumstances pursuant to a contractual arrangement, and we have a similar call option under the same contractual terms. The amount of consideration under the put and call rights is not a fixed amount, but rather is dependent upon various valuation formulas and on future events, such as revenue and gross margin performance of the subsidiary through the date of exercise, as described in Note 15 to the condensed consolidated financial statements. Management estimates, assuming that the subsidiary owned by us at March 31, 2018 performs over the relevant future periods at its forecasted earnings levels, that these rights, if exercised, could require us in a future period to pay a maximum amount of approximately $8.9 million to the owners of such put rights. This amount has been recorded as redeemable noncontrolling interests on the balance sheet at March 31, 2018.
Other contractual arrangements
We lease certain of our facilities and equipment under non-cancelable operating leases. For the quarters ended March 31, 2018 and 2017, rent expense under operating leases was $4.3 million and $3.7 million, respectively.
Certain of our acquisition purchase agreements contain earnout payment provisions under which the sellers of the acquired businesses can earn additional amounts. The total amount of liabilities recorded for these earnouts is $2.6 million and $5.1 million at March 31, 2018 and December 31, 2017, respectively.
29

Off-balance sheet arrangements
We have no off-balance sheet arrangements and do not utilize any “structured debt,” “special purpose,” or similar unconsolidated entities for liquidity or financing purposes.

Item 4. Controls and Procedures.
Evaluation of disclosure controls and procedures
As of March 31, 2018, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) pursuant to Rules 13a-15 and 15d-15 under the Exchange Act. These controls and procedures were designed to provide reasonable assurance that the information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, in a manner to allow timely decisions regarding required disclosures. Based on this evaluation, including an evaluation of the rules referred to above in this Item 4, management has concluded that our disclosure controls and procedures were effective as of March 31, 2018 to provide reasonable assurance that the information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, in a manner to allow timely decisions regarding required disclosures.
