Summary of Significant Accounting Policies | |
Summary of Significant Accounting Policies | Note 2. Summary of Significant Accounting Policies The accompanying consolidated financial statements reflect the application of certain significant accounting policies as described in this note and elsewhere in the footnotes. (a) Basis of Presentation The accompanying consolidated financial statements include the consolidated accounts of the Company and its wholly-owned, controlled subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Events occurring subsequent to December 31, 2020 have been evaluated for potential recognition or disclosure in the consolidated financial statements. (b) Use of Estimates The preparation of these consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, the realizable value of accounts receivable and inventories, valuing stock-based compensation instruments and reserves relating to tax assets and liabilities. Actual amounts could differ from these estimates. Changes in estimates are recorded in the period in which they become known. (c) Foreign Currency The functional currency for substantially all operations outside the United States is the local currency. Financial statements for these operations are translated into United States dollars at year-end rates as to assets and liabilities and average exchange rates during the year as to revenue and expenses. The resulting translation adjustments are recorded in stockholders’ equity as an element of accumulated other comprehensive income (loss). Foreign currency transaction gains and losses are included in other income (expense) in the Consolidated Statements of Operations. For the year ended December 31, 2020 we had $1.4 million in foreign exchange gain. For the year ended December 31, 2019 we had $0.6 million in foreign exchange loss. For the year ended December 31, 2018 we had $1.3 million in foreign exchange loss. (d) Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and highly liquid investments with original maturities of ninety days or less. Cash equivalents consist primarily of money market funds, U.S. Government and Agency Securities and deposit accounts. Cash equivalents are carried on the balance sheet at fair market value. (e) Inventories Inventories are carried at the lower of cost or net realizable value, determined using the first-in, first-out (“FIFO”) method. We periodically review our inventories and make provisions as necessary for estimated obsolescence or damaged goods to ensure values approximate lower of cost or net realizable value. The amount of such markdowns is equal to the difference between cost of inventory and the estimated market value based upon assumptions about future demands, selling prices, and market conditions. We record a provision for estimated excess inventory. The provision is determined using management’s assumptions of materials usage, based on estimates of demand, market conditions, and the size and utilization of our installed base. If actual market conditions become less favorable than those projected by management, additional inventory write-downs may be required. (f) Property, Plant and Equipment and Leased Assets Property, plant and equipment are stated at cost, less accumulated depreciation and amortization. On January 30, 2015, we sold our corporate headquarters facility. As part of this sale, we also entered into a 22-year lease agreement. We accounted for the sale leaseback transaction as a financing arrangement for financial reporting purposes. We retained the historical costs of the property and the related accumulated depreciation on our financial books within property, plant and equipment and will continue to depreciate the property for financial reporting purposes over the lesser of its remaining useful life or its initial lease term of 22 years On January 1, 2019, we adopted Accounting Standard Update (“ASU”) No. 2016-02 “Leases.” Depreciation and amortization are recorded using the straight-line method over the estimated useful lives of the related assets as follows: Asset Classification Estimated Useful Life Land, buildings and equipment (under lease) Lesser of the lease term or estimated useful life of the asset Machinery and equipment 3 to 10 years Repairs and maintenance costs are expensed as incurred. Expenditures greater than $2.5 thousand for renewals and betterments are capitalized and depreciated over their useful lives. (g) Impairment of Long-Lived Assets We record impairment losses on long-lived assets when events and circumstances indicate that these assets might not be recoverable. Recoverability is assessed by a comparison of the assets’ carrying amount to their expected future undiscounted net cash flows. If such assets are considered to be impaired, the impairment is measured based on the amount by which the carrying value exceeds its fair value. We did not have any indicators of impairment during the period ending December 31, 2020. We did not record an impairment charge in the years ended December 31, 2020, 2019, or 2018. Actual performance could be materially different from our current forecasts, which could impact estimates of undiscounted cash flows and may result in the impairment of the carrying amount of the long-lived assets in the future. This could be caused by strategic decisions made in response to economic and competitive conditions, the impact of the economic environment on our customer base, or a material adverse change in our relationships with significant customers. (h) Concentration of Risk and Off-Balance Sheet Risk Financial instruments that potentially subject us to concentrations of credit risk are principally cash equivalents and accounts receivable. Our cash equivalents are principally maintained in investment grade money-market funds, U.S. Government and Agency Securities and deposit accounts. We have no significant off-balance-sheet risk such as currency exchange contracts, option contracts or other hedging arrangements. Our exposure to market risk for changes in interest rates relates primarily to cash equivalents. The primary objective of our investment activities is to preserve principal without significantly increasing risk. This is accomplished by investing in marketable investment grade securities. We do not use derivative financial instruments to manage our investment portfolio and do not expect operating results or cash flows to be affected to any significant degree by any change in market interest rates. We perform ongoing credit evaluations of our customers’ financial condition and generally require no collateral to secure accounts receivable. For selected overseas sales, we require customers to obtain letters of credit before product is shipped. We maintain an allowance for doubtful accounts based on our assessment of the collectability of accounts receivable. We review the allowance for doubtful accounts quarterly. We do not have any off-balance sheet credit exposure related to our customers. Our customers consist of semiconductor chip manufacturers located throughout the world and net sales to our ten largest customers accounted for 74.0%, 74.1% and 76.9% of revenue in 2020, 2019 and 2018, respectively. For the year ended December 31, 2020, we had two customers representing 17.9% and 16.4% of total revenue, respectively. For the year ended December 31, 2019, we had three customers representing 18.2%, 14.2% and 12.0% of total revenue, respectively. For the year ended December 31, 2018 we had two customers representing 20.1% and 12.1% of total revenue, respectively. As of December 31, 2020, we had two customers account for 23.8% and 11.9% of consolidated accounts receivable, respectively. As of December 31, 2019, we had three customers account for 24.9%, 15.3% and 11.1% of consolidated accounts receivable, respectively. Some of the components and sub-assemblies included in our products are obtained either from a sole source or a limited group of suppliers. Disruption to our supply source, resulting either from economic conditions or other factors, could affect our ability to deliver products to our customers. (i) Revenue Recognition Effective January 1, 2018, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods or services. We measure revenue based on the consideration specified in the customer arrangement, and revenue is recognized when the performance obligations in the customer arrangement are satisfied. A performance obligation is a promise in a contract to transfer a distinct product or service to the customer. The transaction price of a contract is allocated to each distinct performance obligation based upon the relative standalone selling price for each performance obligation and recognized as revenue when, or as, the customer receives the benefit of the performance obligation. To account for and measure revenue, we apply the following five steps: 1) Identify the contract with the customer A contract with a customer exists when (i) we enter into an enforceable contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the related payment terms, (ii) the contract has commercial substance, and (iii) we determine that collection of substantially all consideration for goods and services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. 2) Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the goods and services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the good or service either on its own or together with other available resources, and are distinct in the context of the contract, whereby the transfer of the good or service is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised goods and services, we must apply judgment to determine whether promised goods and services are capable of being distinct and distinct in the context of the contract. If these criteria are not met, the promised goods and services are accounted for as a combined performance obligation. Systems sales consist of multiple performance obligations, including the system itself and obligations that are not delivered simultaneously with the system. These undelivered obligations might include a combination of installation services, extended warranty and support and spare parts, all of which are generally covered by a single sales price. The aftermarket business includes both products and services type arrangements. Performance obligations in these contracts consist of used tools, spare parts, equipment upgrades, maintenance services and customer training. Customers who purchase new systems are provided an assurance-type warranty for one year after acceptance of the tool. For aftermarket transactions, we provide customers an assurance-type warranty for 90 days. Customers can choose to purchase extended warranty terms with enhanced support similar to a service-type warranty ranging from one . In accordance with ASC 606, assurance-type warranties are not considered a performance obligation, whereas service-type warranties are. 3) Determine the transaction price The transaction price is determined based on the consideration to which we will be entitled in exchange for transferring goods and services to the customer. To the extent the transaction price includes variable consideration, we estimate the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in our judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Any estimates, including the effect of the constraint on variable consideration, are evaluated at each reporting period for any changes. In applying this guidance, Companies must also consider whether any significant financing components exist. The transaction price for all transactions is based on the price reflected in the individual customer’s purchase order. Variable consideration has not been identified as a significant component of the transaction price for any of our transactions. For those transactions where all performance obligations will be satisfied within one year or less, we apply the practical expedient outlined in ASC 606-10-32-18. This practical expedient allows us not to adjust promised consideration for the effects of a significant financing component if we expect at contract inception that the period between when we transfer the promised good or service to a customer and when the customer pays for that good or service will be one year or less. For those transactions that are expected to be completed after one year, we have assessed that there are no significant financing components because any difference between the promised consideration and the cash selling price of the good or service is for reasons other than the provision of financing. 4) Allocate the transaction price to performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation on a relative standalone selling price basis unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a single performance obligation. Where required, we determine standalone selling price (SSP) for each obligation based on consideration of both market and Company specific factors, including the selling price and profit margin for similar products, the cost to produce, and the anticipated margin. For those contracts that contain multiple performance obligations (primarily systems sales, as well as some aftermarket contracts requiring both time and material inputs), we must determine the SSP. We use a cost plus margin approach in determining the SSP for any materials related performance obligations (such as upgrades, spare parts, systems). To determine the SSP for labor related performance obligations (such as the labor component of installation), we use directly observable inputs based on the standalone sale prices for these services. 5) Recognize revenue when or as we have satisfied a performance obligation We satisfy performance obligations either over time or at a point in time. Revenue is recognized over time if either 1) the customer simultaneously receives and consumes the benefits provided by the entity’s performance, 2) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or 3) the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. If the entity does not satisfy a performance obligation over time, the related performance obligation is satisfied at a point in time by transferring the control of a promised good or service to a customer. Examples of control are using the asset to produce goods or services, enhance the value of other assets or settle liabilities, and holding or selling the asset. For over time recognition, ASC 606 requires us to select a single revenue recognition method for the performance obligation that faithfully depicts our performance in transferring control of the goods and services. The guidance allows entities to choose between two methods to measure progress toward complete satisfaction of a performance obligation: Output methods - recognize revenue on the basis of direct measurements of the value to the customer of the goods or services transferred to date relative to the remaining goods or services promised under the contract (e.g. surveys of performance completed to date, appraisals of results achieved, milestones reached, time elapsed, and units produced or units delivered); and Input methods - recognize revenue on the basis of the entity’s efforts or inputs to the satisfaction of a performance obligation (e.g., resources consumed, labor hours expended, costs incurred, or time elapsed) relative to the total expected inputs to the satisfaction of that performance obligation. We have the right to consideration from a customer in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date (i.e., certain aftermarket contracts), as such we have elected a practical expedient to recognize revenue in the amount to which the entity has a right to invoice for such services. Product related revenues (whether for systems or aftermarket business) are recognized at a point in time, when they are shipped or delivered, depending on shipping terms. For installation services, revenue is recognized at a point in time, once the installation of the tool is complete. The nature of the installation services is such that the customer does not simultaneously receive and consume the benefits provided by the entity’s performance, nor does performance of installation services create or enhance an asset that the customer controls. Installation services do not create an asset with an alternative use to the entity, and the entity does not have an enforceable right to payment for performance completed to date. Contract liabilities are reflected as deferred revenue on the consolidated balance sheet. Contract liabilities relate to payments invoiced or received in advance of completion of performance obligations under a contract. Contract liabilities are recognized as revenue upon the fulfillment of performance obligations. Service-type warranties for any product are recognized over time, as these represent a stand ready obligation to service the product during the warranty period. Progress in the satisfaction of these performance obligations is measured using an input method of time elapsed. Maintenance and service contracts are recognized over time. Progress in the satisfaction of these performance obligations is measured using an input method of either time elapsed in the case of fixed period contracts, or labor hours expended, in the case of project-based contracts. (j) Recognizing Assets related to Recoverable Customer Contract Costs We recognize an asset related to incremental costs incurred by us to obtain a contract with a customer if we expect to recover those costs. We will recognize an asset from costs incurred to fulfill a contract only if such costs relate directly to a contract with an entity that we can specifically identify, the costs incurred will generate or enhance resources that will be used in satisfying performance obligations in the future, and the costs are expected to be recovered. Any assets recognized related to costs to obtain or fulfill a contract are amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. In substantially all of our business transactions, we incur incremental costs to obtain contracts with customers, in the form of sales commissions. We maintain a commission program which awards our employees for System sales, aftermarket activity and other individual goals. Under ASC 606, an asset is amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. However, ASC 606 provides a practical expedient to allow for the recognition of commission expense when incurred if the amortization period of the asset that the entity otherwise would have recognized is one year or less. Based on the nature of our commission agreements, all commissions are expensed as incurred based upon the expectation that the amortization period would be one year or less. (k) Shipping and Handling Costs Shipping and handling costs are included in cost of revenue. (l) Stock-Based Compensation We generally recognize compensation expense for all stock-based payments to employees and directors, including grants of stock options and restricted stock units, based on the grant-date fair value of those stock-based payments. For stock option awards, we use the Black-Scholes option pricing model, adjusted for expected forfeitures. Other valuation models may be utilized in the limited circumstances where awards with market-based vesting considerations, such as the price of our common stock, or performance-based awards, are granted. Stock-based compensation expense is recognized ratably over the requisite service period. For each stock option or restricted stock unit grant with vesting based on a combination of time, market or performance conditions, where vesting will occur if either condition is met, the related compensation costs are recognized over the shorter of the explicit service period or the derived service period. See Note 13 for additional information relating to stock-based compensation. (m) Income Taxes We record income taxes using the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax basis, and operating loss and tax credit carryforwards. Our consolidated financial statements contain certain deferred tax assets which have arisen primarily as a result of operating losses, as well as other temporary differences between financial and tax basis accounting. We establish a valuation allowance if the likelihood of realization of the deferred tax assets is reduced based on an evaluation of objective verifiable evidence. Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against those net deferred tax assets. We evaluate the weight of all available evidence to determine whether it is more likely than not that some portion or all of the net deferred income tax assets will not be realized. Income taxes include the largest amount of tax benefit for an uncertain tax position that is more likely than not to be sustained upon audit based on the technical merits of the tax position. Settlements with tax authorities, the expiration of statutes of limitations for particular tax positions, or obtaining new information on particular tax positions may cause a change to the effective tax rate. We recognize accrued interest related to unrecognized tax benefits as interest expense and penalties within operating expense in the consolidated statements of operations. See Note 18 for additional information relating to income taxes. (n) Computation of Net Income per Share Basic earnings per share is computed by dividing income available to common stockholders (the numerator) by the weighted-average number of common shares outstanding (the denominator) for the period. The computation of diluted earnings per share is similar to basic earnings per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common shares had been issued, calculated using the treasury stock method. The components of net income per share are as follows: Year ended December 31, 2020 2019 2018 (in thousands, except per share data) Net income available to common stockholders $ 49,982 $ 17,034 $ 45,885 Weighted average common shares outstanding used in computing basic income per share 33,257 32,559 32,286 Incremental options and RSUs 871 1,269 1,716 Weighted average common shares used in computing diluted net income per share 34,128 33,828 34,002 Net income per share Basic $ 1.50 $ 0.52 $ 1.42 Diluted $ 1.46 $ 0.50 $ 1.35 Diluted weighted average common shares outstanding does not include restricted stock units outstanding to purchase 1,951 common equivalent shares and 232,844 common equivalent shares for the periods ended December 31, 2020 and 2019, respectively, as their effect would have been anti-dilutive.

Revenue | Note 3. Revenue We design, manufacture and service ion implantation and other processing equipment used in the fabrication of semiconductor chips and sell our products to leading semiconductor chip manufacturers worldwide. We offer a complete line of high energy, high current and medium current implanters for all application requirements. In addition, we provide extensive aftermarket lifecycle products and services, including used tools, spare parts, equipment upgrades, maintenance service and customer training. Our revenue recognition policies are set forth in Section (i) of Note 2, Summary of Significant Accounting Policies. (a) Alternative Operational Revenue Categories used by Management To reflect the organization of our business operations, management reviews revenue in two categories: revenue from sales of new systems and revenue arising from the sale of used systems, parts and labor to customers who own systems, which we refer to as “CS&I” or “aftermarket.” Below are the revenues by categories used by management for the periods covered in this report: Year ended December 31, 2020 2019 2018 (in thousands) Systems $ 293,624 $ 202,571 $ 280,388 CS&I/Aftermarket 180,936 140,387 162,187 Total Revenue $ 474,560 $ 342,958 $ 442,575 (b) Economic Factors Affecting our Revenue: Geographic Breakdown of Revenue Global economic conditions have a direct impact on our revenue. We are substantially dependent on sales of our products and services to customers outside the United States. Adverse economic conditions, political instability, potential adverse tax consequences, regulatory changes and volatility in exchange rates pose a risk that our clients may reduce, postpone or cancel spending for our products and services, which would impact our revenue. Revenue by geographic markets is determined based upon the location to which our products are shipped and where our services are performed. Revenue in our principal geographic markets is as follows: Year ended December 31, 2020 2019 2018 (in thousands) North America $ 50,786 $ 36,206 $ 54,790 Asia Pacific 385,233 251,020 326,191 Europe 38,541 55,732 61,594 Total Revenue $ 474,560 $ 342,958 $ 442,575 (c) Recognition of Deferred Revenue from Contract Liabilities Contract liabilities are as follows: Year ended December 31, 2020 2019 2018 (in thousands) Balance, beginning of the period $ 29,251 $ 22,584 $ 18,145 Deferral of revenue 17,862 24,403 17,284 Recognition of deferred revenue (24,055) (17,736) (12,845) Balance, end of the period $ 23,058 $ 29,251 $ 22,584 Contract liabilities are reflected as deferred revenue on the consolidated balance sheet. Contract liabilities relate to payments received or amounts invoiced in advance of completion of performance obligations under a contract. Contract liabilities are recognized as revenue upon the fulfillment of performance obligations. As of December 31, 2020, we had deferred revenue of $23.1 million. This represents the portion of the transaction price for contracts with customers allocated to the performance obligations that remain unsatisfied or partially unsatisfied. Short-term deferred revenue of The majority of our system transactions have payment terms that are 90% due upon shipment of the tool and 10% due upon installation. Aftermarket transaction payment terms are such that payment is due either within 30 or 60 days of service provided or delivery of parts. |

Accounts Receivable and Allowance for Credit Losses | Note 5. Accounts Receivable and Allowance for Credit Losses All trade receivables are reported on the Consolidated Balance Sheets at their amortized cost adjusted for any write-offs and net of allowances for credit losses. Axcelis maintains an allowance for credit losses, which represents an estimate of expected losses over the remaining contractual life of its receivables considering current market conditions and estimates for supportable forecasts when appropriate. The estimate is a result of the Company’s ongoing assessments and evaluations of collectability, historical loss experience, and future expectations in estimating credit losses in its receivable portfolio. Axcelis uses historical loss experience rates and applies them to a related aging analysis while also considering customer and/or economic risk where appropriate. Determination of the proper amount of allowances requires management to exercise judgment about the timing, frequency and severity of credit losses that could materially affect the provision for credit losses and, as a result, net earnings. The allowance takes into consideration numerous quantitative and qualitative factors that include receivable type, historical loss experience, delinquency trends, collection experience, current economic conditions, estimates for supportable forecasts, when appropriate, and credit risk characteristics. Axcelis evaluates the credit risk of the customer when extending credit based on a combination of various financial and qualitative factors that may affect its customers’ ability to pay. These factors may include the customer’s financial condition, past payment experience, and credit ratings from credit bureaus, as well as the value of the underlying collateral. Management performs detailed reviews of its receivables on a quarterly basis to assess the adequacy of the allowances and to determine if any impairment has occurred. Amounts determined to be uncollectable are charged directly against the allowance, while amounts recovered on previously written-off accounts increase the allowance. Changes to the allowance for credit losses are maintained through adjustments to the provision for credit losses, which are charged to current period earnings. The following table shows changes of the allowances for credit losses related to trade receivables for the twelve months ended December 31, 2020 and 2019, respectively: Year ended December 31, 2020 2019 (in thousands) Balance, beginning of period $ 818 $ — Provision for credit losses — 818 Charge-offs (818) Recoveries — — Balance, end of period $ — $ 818 The components of accounts receivable are as follows: December 31, 2020 2019 (in thousands) Trade receivables $ 86,865 $ 84,571 Allowance for doubtful accounts — (818) Trade receivables, net $ 86,865 $ 83,753 |

Leases | |
Leases | Note 9. Leases We have operating leases for office space, warehouse space, computer and office equipment and vehicles used in our business operations. We have a finance lease in relation to the 2015 sale-leaseback of our corporate headquarters in Beverly, Massachusetts. We review all agreements to determine if the agreement contains a lease component. An agreement contains a lease component if it provides the use of a specific physical space or a specific physical item. Upon adoption of Topic 842 on January 1, 2019, we recognized operating lease obligations on a discounted basis using the explicit or implicit discount rate stated within the agreement. We recognize a corresponding right-of-use asset, which is initially determined based upon the net present value of the associated liability and is adjusted for deferred costs and possible impairment, if any. For those lease agreements that do not indicate the applicable discount rate, we use our incremental borrowing rate. The value of the right-of-use asset is initially determined based on the net present value of the associated liability, and is adjusted for deferred costs and possible impairments, if any. We have made the following policy elections: (i) operating leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet; (ii) we recognize lease expense for operating leases on a straight-line basis over the lease term; and (iii) we account for lease components and non-lease components that are fixed payments as one component. Some of our operating leases include one or more options to renew, with renewal terms that can extend the respective lease term 1 to 3 years. The exercise of lease renewal options is at our sole discretion. For lease extensions that are reasonably certain to occur, we have included the renewal periods in our calculation of the net present value of the lease obligation and related right-of-use asset. Certain leases also include options to purchase the leased property. The depreciable life of certain assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The amounts of operating and finance lease right-of-use assets and related lease obligations recorded within our consolidated balance sheets are as follows: December 31, Leases Classification 2020 2019 Assets (in thousands) Operating lease Operating lease assets $ 4,542 $ 5,849 Finance lease Finance lease assets * 20,544 21,880 Total leased assets $ 25,086 $ 27,729 Liabilities Current Operating Other current liabilities $ 2,573 $ 3,144 Finance Current portion of finance lease obligation 756 399 Noncurrent Operating Other long-term liabilities 1,949 2,553 Finance Finance lease obligation 47,393 48,149 Total lease liabilities $ 52,671 $ 54,245 * Finance lease assets are recorded net of accumulated depreciation of $48.4 million and include $0.7 All of our office locations support selling and servicing functions.

Product Warranty | Note 10. Product Warranty We generally offer a one year warranty for all of our systems, the terms and conditions of which vary depending upon the product sold. For all systems sold, we accrue a liability for the estimated cost of standard warranty at the time of system shipment and defer the portion of systems revenue attributable to the fair value of non-standard warranty. Costs for non-standard warranty are expensed as incurred. Factors that affect our warranty liability include the number of installed units, historical and anticipated product failure rates, material usage and service labor costs. We periodically assess the adequacy of our recorded liability and adjust the amount as necessary.

Financing Arrangements | Note 11. Financing Arrangements On January 30, 2015, we sold our corporate headquarters facility for the sale price of $48.9 million. As part of the sale, we also entered into a 22-year lease agreement with the buyer. The sale leaseback is accounted for as a financing arrangement for financial reporting purposes and, as such, we recorded a financing obligation of $48.1 million as of December 31, 2020, $0.8 million of which is classified within current liabilities. The associated lease payments include both an interest component and payment of principal, with the underlying liability being extinguished at the end of the original lease term. We posted a collateralized security deposit of $5.9 million in the form of an irrevocable letter of credit at the time of the closing. This letter of credit is currently issued under the credit facility described in the next paragraph. On July 31, 2020, we entered into a Senior Secured Credit Facilities Credit Agreement (the “Credit Agreement”) with Silicon Valley Bank, in its capacity as administrative agent and collateral agent for itself and as a lender, and such other banks and financial institutions or entities that from time to time join as lenders under the Credit Agreement. The Credit Agreement provides for a revolving credit facility in an aggregate principal amount not to exceed $40.0 million. Our obligations under the Credit Agreement are secured by a security interest, senior to any current and future debts and to any security interest, in all of our rights, title, and interest in, to and under substantially all of our assets, subject to limited exceptions, including permitted liens. The revolving credit facility terminates on July 31, 2023. As of December 31, 2020, we were in compliance with all covenant requirements of the Credit Agreement. As of such date, no borrowings had been made under the Credit Agreement, although a letter of credit for $5.9 million, previously issued by Silicon Valley Bank, had been rolled under the Credit Agreement, reducing the funds available for borrowing under the credit line. |

Employee Benefit Plans | Note 12. Employee Benefit Plans (a) Defined Contribution Plan We maintain the Axcelis Long-Term Investment Plan, a defined contribution plan. Eligible employees may contribute up to 35% of their compensation on a before-tax basis subject to Internal Revenue Service (“IRS”) limitations. Highly compensated employees may contribute up to 16% of their compensation on a before-tax basis subject to IRS limitations. In 2020, 2019 and 2018 we provided an employer match of 50% of employees’ pre-tax contributions on the first 6% of eligible compensation. Total related matching contribution expense was $2.0 million, $1.9 million and $1.6 million, for 2020, 2019 and 2018, respectively. (b) Other Compensation Plans We operate in foreign jurisdictions that require lump sum benefits, payable based on statutory regulations, for voluntary or involuntary termination. Where required, an annual actuarial valuation of the benefit plans is obtained. We have recorded an unfunded liability of $5.1 million and $4.8 million at December 31, 2020 and 2019, respectively, for costs associated with these compensation plans in foreign jurisdictions. The following table presents the classification of these liabilities in the Consolidated Balance Sheets: Year ended December 31, 2020 2019 (in thousands) Current: Accrued compensation $ 1,218 $ 1,040 Total current liabilities $ 1,218 $ 1,040 Long-term: Other long-term liabilities 3,903 3,753 Total liabilities $ 5,121 $ 4,793 The expense recorded in connection with these plans was $1.2 million, $1.2 million and $1.3 million during the years ended December 31, 2020, 2019 and 2018, respectively. |

Our 2000 Stock Plan (the “2000 Stock Plan”) expired on May 1, 2012 and no new grants may be made under that plan after that date. However, awards granted under the 2000 Stock Plan prior to the expiration remain outstanding and subject to the terms of the 2000 Stock Plan. The 2012 Equity Plan, as amended, reserves 9.5 million shares of common stock, $0.001 par value, for grant and permits the issuance of options, stock appreciation rights, restricted stock, restricted stock units, stock equivalents and awards of shares of common stock that are not subject to restrictions or forfeiture to selected employees, directors and consultants of the Company. The 2012 Equity Plan includes shares specifically approved by the stockholders of the Company. Shares that are not issued under an award (because such award expires, is terminated unexercised or is forfeited) revert back to the Plan. The reserve under the Plan is also increased by expirations and forfeitures of awards outstanding under the 2000 Stock Plan as of May 2, 2012. The term of stock options granted under these plans is specified in the award agreements. Unless a lesser term is otherwise specified by the Compensation Committee of the Company’s Board of Directors, awards under the 2012 Equity Plan will expire seven years from the date of grant. In general, all awards issued under the 2000 Stock Plan expire ten years from the date of grant. Under the terms of these stock plans, the exercise price of a stock option may not be less than the fair market value of a share of the Company’s common stock on the date of grant. Under the 2012 Equity Plan, fair market value is defined as the last reported sale price of a share of the Company’s common stock on a national securities exchange as of any applicable date, as long as the Company’s shares are traded on such exchange. Stock options granted to employees generally vest over a period of four years, while stock options granted to non-employee members of the Company’s Board of Directors generally vest over a period of six months and, once vested, are not affected by the director’s termination of service to the Company. In limited circumstances, the Company may grant stock option awards with market-based vesting conditions, such as the Company’s common stock price, or other performance conditions. Termination of service by an employee will cause options to cease vesting as of the date of termination, and in most cases, employees will have 90 days after termination to exercise options that were vested as of the termination of employment. In general, retiring employees will have one year after termination of employment to exercise vested options. The Company settles stock option exercises with newly issued common shares. Restricted stock units granted to employees during 2020 had both service-based vesting provisions and performance-based vesting provisions. Restricted stock units granted to employees generally vest over a service period of four years, while restricted stock units granted to non-employee members of the Company’s Board of Directors generally vest over a service period of six months. We have granted restricted stock units to executive officers and other senior employees with performance vesting conditions, which may be subject to further service-based vesting terms. Unvested restricted stock unit awards expire upon termination of service to the Company. We settle restricted stock units upon vesting with newly issued common shares. No restricted stock was granted under either stock plan during the three year period ended December 31, 2020. As of December 31, 2020, there were 1.9 million shares available for grant under the 2012 Equity Plan. No shares are available for grant under the 2000 Stock Plan. As of December 31, 2020, there were 0.5 million options outstanding under the 2012 Equity Plan and the 2000 Stock Plan, collectively, and 1.1 million unvested restricted stock units outstanding under the 2012 Stock Plan. (b) Employee Stock Purchase Plan The 2020 Employee Stock Purchase Plan (the “2020 ESPP”) provides effectively all of our employees the opportunity to purchase common stock of the Company at less than market prices. Purchases are made through payroll deductions of up to 10% of the employee’s salary as elected by the participant, subject to certain caps set forth in the 2020 ESPP. Employees may purchase the Company’s common stock at 85% of its market price on the day the stock is purchased. The 2020 ESPP is considered compensatory and as such, compensation expense has been recognized based on the benefit of the discounted stock price, amortized to compensation expense over each offering period of six months. Compensation expense relating to the 2020 ESPP and our prior employee stock purchase plan (“Purchase Plan”) was approximately $0.2 million for the years ended December 31, 2020. Compensation expense under the Purchase Plan was approximately $0.2 million for the years ended December 31, 2019 and 2018. As of December 31, 2020, there were approximately 1.0 million shares reserved for issuance and available for purchase under the 2020 ESPP, with 20,216 shares purchased on that date to be issued pending settlement. The Company’s Employee Stock Purchase plan effective in June 2000 (the “2000 ESPP”) expired in June 2020. Less than 0.1 million shares were purchased under the 2000 ESPP in each of the years ended December 31, 2020, 2019 and 2018. (c) Valuation of Stock Options and Restricted Stock Units For the purpose of valuing stock options with service conditions, we use the Black-Scholes option pricing model to calculate the grant-date fair value of an award. There were no stock option awards granted in 2020, 2019 and 2018. The fair value of the Company’s restricted stock units is calculated based upon the fair market value of the Company’s stock at the date of grant. (d) Summary of Stock-based Compensation Expense We use the straight-line attribution method to recognize expense for stock-based awards such that the expense associated with awards is evenly recognized throughout the period. The amount of stock-based compensation recognized is based on the value of the portion of the awards that are ultimately expected to vest. We estimate forfeitures at the time of grant and revise them, if necessary, in subsequent periods, if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered stock-based award. Based on a historical analysis, a forfeiture rate of 5% per year was applied to stock-based awards, including executive officer awards, for the years ended December 31, 2020, 2019 and 2018. For the years ended December 31, 2020, 2019 and 2018, we recognized stock-based compensation expense of $10.5 million, $8.2 million and $7.8 million, respectively. We present the expenses related to stock-based compensation in the same expense line items as cash compensation paid to our employees. For the years ended December 31, 2020, 2019 and 2018, we used restricted stock units in our annual equity compensation program. The benefit of tax deductions in excess of recognized compensation cost is reported in the consolidated statements of cash flows as part of cash flows from operating activities. Axcelis had tax deductions in excess of recognized compensation cost of $14.6 million for the year ended December 31, 2020 which resulted in a tax benefit of $3.1 million. (e) Stock Option Awards The following table summarizes the stock option activity for the year ended December 31, 2020: Weighted Weighted Average Average Remaining Aggregate Exercise Contractual Intrinsic Options Price Term Value (in thousands) (years) (in thousands) Outstanding at December 31, 2019 1,506 $ 8.92 Granted — — Exercised (1,000) 8.41 Canceled (1) 7.2 Expired (1) 7.2 Outstanding at December 31, 2020 504 $ 9.93 1.14 $ 9,678 Exercisable at December 31, 2020 504 $ 9.93 1.14 $ 9,678 Options Vested at December 31, 2020 504 $ 9.93 1.14 $ 9,678 The total intrinsic value, which is defined as the difference between the market price at exercise and the price paid by the employee to exercise the options, for options exercised during the years ended December 31, 2020, 2019 and 2018 was $18.4 million, $10.9 million and $4.1 million, respectively. The total fair value of stock options vested during the years ended December 31, 2020, 2019 and 2018 was $0.1 million, $0.9 million and $1.9 million respectively. As of December 31, 2020, there was no unrecognized compensation cost related to non-vested stock options granted under the 2012 Equity Incentive Plan and the 2000 Stock Plan. (f) Restricted Stock Units and Restricted Stock Restricted stock units represent the Company’s unfunded and unsecured promise to issue shares of the common stock at a future date, subject to the terms of the Award Agreement issued under the 2012 Equity Incentive Plan. Restricted stock unit awards granted in 2020 included time vested share awards and awards with performance vesting conditions. Restricted stock awards are issued shares of common stock that are subject to forfeiture on terms described in the Award Agreement, and may be granted under the 2012 Equity Incentive Plan. No restricted stock awards were granted, or vested, during the years ended December 31, 2020, 2019 and 2018. The fair value of a restricted stock unit and restricted stock award is charged to expense ratably over the applicable service period. The purpose of these awards is to assist in attracting and retaining highly competent employees and directors and to act as an incentive in motivating selected employees and directors to achieve long-term corporate objectives. Changes in the Company’s non-vested restricted stock units for the year ended December 31, 2020 is as follows: Weighted-Average Grant Date Fair Shares/units Value per Share (in thousands) Outstanding at December 31, 2019 1,122 $ 18.15 Granted 517 23.60 Vested (528) 18.08 Forfeited (22) 18.39 Outstanding at December 31, 2020 1,089 $ 20.77 The weighted average grant-date fair value of restricted stock units granted for the years ended December 31, 2020, 2019 and 2018 was $23.60, $17.08 and $22.41, respectively. Most restricted stock units provide for net share settlement to cover the employee’s personal income tax withholding obligations on vesting of the employee’s restricted stock units. Vesting activity above reflects shares vested before net share settlement. As of December 31, 2020, there was $16.8 million of total forfeiture-adjusted unrecognized compensation cost related to non-vested restricted stock units granted under the 2012 Equity Incentive Plan. That cost is expected to be recognized over a weighted-average period of 2.4 years. |

Stockholders' Equity | Note 14. Stockholders’ Equity We may issue up to 75 million shares of common stock without additional shareholder approval. As of December 31, 2020 and 2019, there were 33.6 million and 32.6 million outstanding shares of common stock, respectively. On January 12, 2021, we announced that our Board of Directors authorized a one-year share repurchase program of up to $100 million of our common stock. These shares may be purchased in the open market or through privately negotiated transactions. We have no obligation to repurchase shares under the authorization, and the timing, actual number and value of shares which are repurchased will depend on a number of factors, including the price of our common stock, general business and market conditions, and alternative investment opportunities. We may suspend or discontinue the repurchase program at any time. |

Fair Value Measurements | Note 15. Fair Value Measurements Fair value is defined 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. (a) Fair Value Hierarchy The accounting guidance for fair value measurement requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows: Level 1 Level 2 (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. Level 3 (b) Assets and Liabilities Measured at Fair Value Our money market funds and short-term investments are included in cash and cash equivalents in the consolidated balance sheets. The following table sets forth Company’s assets which are measured at fair value by level within the fair value hierarchy. December 31, 2020 Fair Value Measurements Level 1 Level 2 Level 3 Total (in thousands) Assets Cash equivalents: Money market funds, U.S. Government Securities and Agency Investments $ 172,119 $ — $ — $ 172,119 December 31, 2019 Fair Value Measurements Level 1 Level 2 Level 3 Total (in thousands) Assets Cash equivalents: Money market funds, U.S. Government Securities and Agency Investments $ 92,872 $ 24,000 $ — $ 116,872 (c) Other Financial Instruments The carrying amounts reflected in the consolidated balance sheets for accounts receivable, prepaid expenses and other current and non-current assets, restricted cash, accounts payable and accrued expenses approximate fair value due to their short-term maturities. |

Commitments and Contingencies | Note 16. Commitments and Contingencies (a) Lease Commitments We lease manufacturing and office facilities and certain equipment under operating and capital leases that expire through 2037. Rental expense was $5.2 million, $4.8 million and $4.6 million under operating leases for the years ended December 31, 2020, 2019 and 2018, respectively. Future minimum lease commitments on non-cancelable operating leases for the year ended December 31, 2020 are as follows: Operating Leases (in thousands) 2021 $ 2,808 2022 1,441 2023 430 2024 118 2025 77 Thereafter 151 Total operating lease payments $ 5,025 (b) Sale Leaseback Financing Obligation In addition to the lease commitments as described above, in 2015 we entered into a 22-year lease agreement relating to our corporate headquarters in Beverly, Massachusetts. The following table relates to the cash payment schedule associated with this lease obligation as of December 31, 2020: Lease Obligation (in thousands) 2021 $ 5,848 2022 5,980 2023 6,114 2024 6,252 2025 5,930 Thereafter 73,723 Total finance lease payments $ 103,847 Less interest portion (55,698) Sale leaseback obligation $ 48,149 (c) Purchase Commitments We have contracts and purchase orders for inventory and other expenditures of $92.7 million at December 31, 2020. (d) Litigation We are not presently a party to any litigation that we believe might have a material adverse effect on our business operations. We are, from time to time, a party to litigation that arises in the normal course of our business operations. (e) Indemnifications Our system sales agreements typically include provisions under which we agree to take certain actions, provide certain remedies and defend our customers against third-party claims of intellectual property infringement under specified conditions and to indemnify customers against any damage and costs awarded in connection with such claims. We have not incurred any material costs as a result of such indemnifications and have not accrued any liabilities related to such obligations in the accompanying consolidated financial statements. |

Business Segment and Geographic Region Information | Note 17. Business Segment and Geographic Region Information We operate in one business segment, which is the manufacture of capital equipment for the semiconductor chip manufacturing industry. The principal market for semiconductor capital equipment is semiconductor chip manufacturers. Substantially all sales are made directly by us to our customers located in the United States, Europe and Asia Pacific. Our ion implantation systems product line includes high current, medium current and high energy implanters. Other legacy processing products include curing and thermal processing systems. In addition to new equipment, we provide post-sales equipment service and support, including spare parts, equipment upgrades, used equipment, maintenance services and customer training.

Our deferred tax assets and liabilities are measured at the enacted tax rate expected to apply when these temporary differences are expected to be realized or settled. At December 31, 2020, we had $57.9 million of deferred tax assets worldwide relating to net operating loss carryforwards, tax credit carryforwards and other temporary differences, which are available to reduce income taxes in future years. At December 31, 2020, we maintain a $9.1 million valuation allowance in the U.S. against certain tax credits and state net operating losses due to the uncertainty of their realization based on long-term Company forecasts and the expiration dates on these attributes. This represents an increase of $0.8 million from the prior year. At December 31, 2020, we have federal and state net operating loss carryforwards of $114.1 million and $17.8 million, respectively. Federal and state net operating losses will expire between 2021 and 2034. The federal net operating loss carryforwards are subject to an uncertain tax position reserve of At December 31, 2020, we have research and development and other tax credit carryforwards of $37.5 million. These carry forwards are subject to an uncertain tax position reserve of $8.8 million. These credits can be used to reduce future federal and state income tax liabilities and expire principally between 2021 and 2040. We consider the undistributed earnings of our foreign subsidiaries as of December 31, 2020, to be indefinitely reinvested and, accordingly, no U.S. income taxes have been provided thereon. As of December 31, 2020, the amount of cash associated with indefinitely reinvested foreign earnings was approximately $14.0 million. We have not, nor do we anticipate the need to, repatriate funds to the United States to satisfy domestic liquidity needs arising in the ordinary course of business, including liquidity needs associated with our domestic debt service requirements. We and our subsidiaries file income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. We and most foreign subsidiaries are subject to income tax examinations by tax authorities for all years dating back to 2009. Our policy is to recognize interest related to unrecognized tax benefits as interest expense and penalties as operating expenses. We believe that we have appropriate support for the income tax positions taken and to be taken on our tax returns and that our accruals for tax liabilities are adequate for all open years based on an assessment of many factors including past experience and interpretations of tax law applied to the facts of each matter. At December 31, 2020, we had unrecognized tax benefits related to uncertain tax positions of approximately $10.0 million, of which approximately $9.6 million reduced the Company’s deferred tax assets and the offsetting valuation allowance and $0.5 million was recorded in other long-term liabilities. A reconciliation of the beginning and ending balance of unrecognized tax benefits are as follows: Year ended December 31, 2020 2019 2018 (in thousands) Balance at beginning of year $ 9,799 $ 9,127 $ 9,105 Increase / (decrease) in unrecognized tax benefits as a result of tax positions taken during a prior period (502) 215 (132) Reductions to unrecognized tax benefits as a result of a lapse of the applicable statute of limitation — (334) (543) Increases in unrecognized tax benefits as a result of tax positions taken during the current period 747 791 697 Balance at end of year $ 10,044 $ 9,799 $ 9,127 Recorded as other long-term liability $ 472 $ 409 $ 676 Recorded as a decrease in deferred tax assets 9,572 9,390 8,451 Balance at end of year $ 10,044 $ 9,799 $ 9,127 As of December 31, 2020 we had $10.0 million of unrecognized tax benefits which, if recognized would reduce the effective tax rate. |

Summary of Significant Accounting Policies (Policies) | 12 Months Ended |

Summary of Significant Accounting Policies | |
Basis of Presentation | (a) Basis of Presentation The accompanying consolidated financial statements include the consolidated accounts of the Company and its wholly-owned, controlled subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Events occurring subsequent to December 31, 2020 have been evaluated for potential recognition or disclosure in the consolidated financial statements. |
Use of Estimates | (b) Use of Estimates The preparation of these consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, the realizable value of accounts receivable and inventories, valuing stock-based compensation instruments and reserves relating to tax assets and liabilities. Actual amounts could differ from these estimates. Changes in estimates are recorded in the period in which they become known. |
Foreign Currency | (c) Foreign Currency The functional currency for substantially all operations outside the United States is the local currency. Financial statements for these operations are translated into United States dollars at year-end rates as to assets and liabilities and average exchange rates during the year as to revenue and expenses. The resulting translation adjustments are recorded in stockholders’ equity as an element of accumulated other comprehensive income (loss). Foreign currency transaction gains and losses are included in other income (expense) in the Consolidated Statements of Operations. For the year ended December 31, 2020 we had $1.4 million in foreign exchange gain. For the year ended December 31, 2019 we had $0.6 million in foreign exchange loss. For the year ended December 31, 2018 we had $1.3 million in foreign exchange loss. |
Cash and Cash Equivalents | (d) Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and highly liquid investments with original maturities of ninety days or less. Cash equivalents consist primarily of money market funds, U.S. Government and Agency Securities and deposit accounts. Cash equivalents are carried on the balance sheet at fair market value. |
Inventories | (e) Inventories Inventories are carried at the lower of cost or net realizable value, determined using the first-in, first-out (“FIFO”) method. We periodically review our inventories and make provisions as necessary for estimated obsolescence or damaged goods to ensure values approximate lower of cost or net realizable value. The amount of such markdowns is equal to the difference between cost of inventory and the estimated market value based upon assumptions about future demands, selling prices, and market conditions. We record a provision for estimated excess inventory. The provision is determined using management’s assumptions of materials usage, based on estimates of demand, market conditions, and the size and utilization of our installed base. If actual market conditions become less favorable than those projected by management, additional inventory write-downs may be required. |
Property, Plant and Equipment | (f) Property, Plant and Equipment and Leased Assets Property, plant and equipment are stated at cost, less accumulated depreciation and amortization. On January 30, 2015, we sold our corporate headquarters facility. As part of this sale, we also entered into a 22-year lease agreement. We accounted for the sale leaseback transaction as a financing arrangement for financial reporting purposes. We retained the historical costs of the property and the related accumulated depreciation on our financial books within property, plant and equipment and will continue to depreciate the property for financial reporting purposes over the lesser of its remaining useful life or its initial lease term of 22 years On January 1, 2019, we adopted Accounting Standard Update (“ASU”) No. 2016-02 “Leases.” Depreciation and amortization are recorded using the straight-line method over the estimated useful lives of the related assets as follows: Asset Classification Estimated Useful Life Land, buildings and equipment (under lease) Lesser of the lease term or estimated useful life of the asset Machinery and equipment 3 to 10 years Repairs and maintenance costs are expensed as incurred. Expenditures greater than $2.5 thousand for renewals and betterments are capitalized and depreciated over their useful lives. |
Impairment of Long-Lived Assets | (g) Impairment of Long-Lived Assets We record impairment losses on long-lived assets when events and circumstances indicate that these assets might not be recoverable. Recoverability is assessed by a comparison of the assets’ carrying amount to their expected future undiscounted net cash flows. If such assets are considered to be impaired, the impairment is measured based on the amount by which the carrying value exceeds its fair value. We did not have any indicators of impairment during the period ending December 31, 2020. We did not record an impairment charge in the years ended December 31, 2020, 2019, or 2018. Actual performance could be materially different from our current forecasts, which could impact estimates of undiscounted cash flows and may result in the impairment of the carrying amount of the long-lived assets in the future. This could be caused by strategic decisions made in response to economic and competitive conditions, the impact of the economic environment on our customer base, or a material adverse change in our relationships with significant customers. |
Concentration of Risk and Off-Balance Sheet Risk | (h) Concentration of Risk and Off-Balance Sheet Risk Financial instruments that potentially subject us to concentrations of credit risk are principally cash equivalents and accounts receivable. Our cash equivalents are principally maintained in investment grade money-market funds, U.S. Government and Agency Securities and deposit accounts. We have no significant off-balance-sheet risk such as currency exchange contracts, option contracts or other hedging arrangements. Our exposure to market risk for changes in interest rates relates primarily to cash equivalents. The primary objective of our investment activities is to preserve principal without significantly increasing risk. This is accomplished by investing in marketable investment grade securities. We do not use derivative financial instruments to manage our investment portfolio and do not expect operating results or cash flows to be affected to any significant degree by any change in market interest rates. We perform ongoing credit evaluations of our customers’ financial condition and generally require no collateral to secure accounts receivable. For selected overseas sales, we require customers to obtain letters of credit before product is shipped. We maintain an allowance for doubtful accounts based on our assessment of the collectability of accounts receivable. We review the allowance for doubtful accounts quarterly. We do not have any off-balance sheet credit exposure related to our customers. Our customers consist of semiconductor chip manufacturers located throughout the world and net sales to our ten largest customers accounted for 74.0%, 74.1% and 76.9% of revenue in 2020, 2019 and 2018, respectively. For the year ended December 31, 2020, we had two customers representing 17.9% and 16.4% of total revenue, respectively. For the year ended December 31, 2019, we had three customers representing 18.2%, 14.2% and 12.0% of total revenue, respectively. For the year ended December 31, 2018 we had two customers representing 20.1% and 12.1% of total revenue, respectively. As of December 31, 2020, we had two customers account for 23.8% and 11.9% of consolidated accounts receivable, respectively. As of December 31, 2019, we had three customers account for 24.9%, 15.3% and 11.1% of consolidated accounts receivable, respectively. Some of the components and sub-assemblies included in our products are obtained either from a sole source or a limited group of suppliers. Disruption to our supply source, resulting either from economic conditions or other factors, could affect our ability to deliver products to our customers. |
Revenue Recognition | (i) Revenue Recognition Effective January 1, 2018, we adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods or services. We measure revenue based on the consideration specified in the customer arrangement, and revenue is recognized when the performance obligations in the customer arrangement are satisfied. A performance obligation is a promise in a contract to transfer a distinct product or service to the customer. The transaction price of a contract is allocated to each distinct performance obligation based upon the relative standalone selling price for each performance obligation and recognized as revenue when, or as, the customer receives the benefit of the performance obligation. To account for and measure revenue, we apply the following five steps: 1) Identify the contract with the customer A contract with a customer exists when (i) we enter into an enforceable contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the related payment terms, (ii) the contract has commercial substance, and (iii) we determine that collection of substantially all consideration for goods and services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. 2) Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the goods and services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the good or service either on its own or together with other available resources, and are distinct in the context of the contract, whereby the transfer of the good or service is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised goods and services, we must apply judgment to determine whether promised goods and services are capable of being distinct and distinct in the context of the contract. If these criteria are not met, the promised goods and services are accounted for as a combined performance obligation. Systems sales consist of multiple performance obligations, including the system itself and obligations that are not delivered simultaneously with the system. These undelivered obligations might include a combination of installation services, extended warranty and support and spare parts, all of which are generally covered by a single sales price. The aftermarket business includes both products and services type arrangements. Performance obligations in these contracts consist of used tools, spare parts, equipment upgrades, maintenance services and customer training. Customers who purchase new systems are provided an assurance-type warranty for one year after acceptance of the tool. For aftermarket transactions, we provide customers an assurance-type warranty for 90 days. Customers can choose to purchase extended warranty terms with enhanced support similar to a service-type warranty ranging from one . In accordance with ASC 606, assurance-type warranties are not considered a performance obligation, whereas service-type warranties are. 3) Determine the transaction price The transaction price is determined based on the consideration to which we will be entitled in exchange for transferring goods and services to the customer. To the extent the transaction price includes variable consideration, we estimate the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in our judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Any estimates, including the effect of the constraint on variable consideration, are evaluated at each reporting period for any changes. In applying this guidance, Companies must also consider whether any significant financing components exist. The transaction price for all transactions is based on the price reflected in the individual customer’s purchase order. Variable consideration has not been identified as a significant component of the transaction price for any of our transactions. For those transactions where all performance obligations will be satisfied within one year or less, we apply the practical expedient outlined in ASC 606-10-32-18. This practical expedient allows us not to adjust promised consideration for the effects of a significant financing component if we expect at contract inception that the period between when we transfer the promised good or service to a customer and when the customer pays for that good or service will be one year or less. For those transactions that are expected to be completed after one year, we have assessed that there are no significant financing components because any difference between the promised consideration and the cash selling price of the good or service is for reasons other than the provision of financing. 4) Allocate the transaction price to performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation on a relative standalone selling price basis unless the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct service that forms part of a single performance obligation. Where required, we determine standalone selling price (SSP) for each obligation based on consideration of both market and Company specific factors, including the selling price and profit margin for similar products, the cost to produce, and the anticipated margin. For those contracts that contain multiple performance obligations (primarily systems sales, as well as some aftermarket contracts requiring both time and material inputs), we must determine the SSP. We use a cost plus margin approach in determining the SSP for any materials related performance obligations (such as upgrades, spare parts, systems). To determine the SSP for labor related performance obligations (such as the labor component of installation), we use directly observable inputs based on the standalone sale prices for these services. 5) Recognize revenue when or as we have satisfied a performance obligation We satisfy performance obligations either over time or at a point in time. Revenue is recognized over time if either 1) the customer simultaneously receives and consumes the benefits provided by the entity’s performance, 2) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or 3) the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. If the entity does not satisfy a performance obligation over time, the related performance obligation is satisfied at a point in time by transferring the control of a promised good or service to a customer. Examples of control are using the asset to produce goods or services, enhance the value of other assets or settle liabilities, and holding or selling the asset. For over time recognition, ASC 606 requires us to select a single revenue recognition method for the performance obligation that faithfully depicts our performance in transferring control of the goods and services. The guidance allows entities to choose between two methods to measure progress toward complete satisfaction of a performance obligation: Output methods - recognize revenue on the basis of direct measurements of the value to the customer of the goods or services transferred to date relative to the remaining goods or services promised under the contract (e.g. surveys of performance completed to date, appraisals of results achieved, milestones reached, time elapsed, and units produced or units delivered); and Input methods - recognize revenue on the basis of the entity’s efforts or inputs to the satisfaction of a performance obligation (e.g., resources consumed, labor hours expended, costs incurred, or time elapsed) relative to the total expected inputs to the satisfaction of that performance obligation. We have the right to consideration from a customer in an amount that corresponds directly with the value to the customer of the entity’s performance completed to date (i.e., certain aftermarket contracts), as such we have elected a practical expedient to recognize revenue in the amount to which the entity has a right to invoice for such services. Product related revenues (whether for systems or aftermarket business) are recognized at a point in time, when they are shipped or delivered, depending on shipping terms. For installation services, revenue is recognized at a point in time, once the installation of the tool is complete. The nature of the installation services is such that the customer does not simultaneously receive and consume the benefits provided by the entity’s performance, nor does performance of installation services create or enhance an asset that the customer controls. Installation services do not create an asset with an alternative use to the entity, and the entity does not have an enforceable right to payment for performance completed to date. Contract liabilities are reflected as deferred revenue on the consolidated balance sheet. Contract liabilities relate to payments invoiced or received in advance of completion of performance obligations under a contract. Contract liabilities are recognized as revenue upon the fulfillment of performance obligations. Service-type warranties for any product are recognized over time, as these represent a stand ready obligation to service the product during the warranty period. Progress in the satisfaction of these performance obligations is measured using an input method of time elapsed. Maintenance and service contracts are recognized over time. Progress in the satisfaction of these performance obligations is measured using an input method of either time elapsed in the case of fixed period contracts, or labor hours expended, in the case of project-based contracts. |
Recognizing Assets related to Recoverable Customer Contract Costs | (j) Recognizing Assets related to Recoverable Customer Contract Costs We recognize an asset related to incremental costs incurred by us to obtain a contract with a customer if we expect to recover those costs. We will recognize an asset from costs incurred to fulfill a contract only if such costs relate directly to a contract with an entity that we can specifically identify, the costs incurred will generate or enhance resources that will be used in satisfying performance obligations in the future, and the costs are expected to be recovered. Any assets recognized related to costs to obtain or fulfill a contract are amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. In substantially all of our business transactions, we incur incremental costs to obtain contracts with customers, in the form of sales commissions. We maintain a commission program which awards our employees for System sales, aftermarket activity and other individual goals. Under ASC 606, an asset is amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. However, ASC 606 provides a practical expedient to allow for the recognition of commission expense when incurred if the amortization period of the asset that the entity otherwise would have recognized is one year or less. Based on the nature of our commission agreements, all commissions are expensed as incurred based upon the expectation that the amortization period would be one year or less. |
Shipping and Handling Costs | (k) Shipping and Handling Costs Shipping and handling costs are included in cost of revenue. |
Stock-Based Compensation | (l) Stock-Based Compensation We generally recognize compensation expense for all stock-based payments to employees and directors, including grants of stock options and restricted stock units, based on the grant-date fair value of those stock-based payments. For stock option awards, we use the Black-Scholes option pricing model, adjusted for expected forfeitures. Other valuation models may be utilized in the limited circumstances where awards with market-based vesting considerations, such as the price of our common stock, or performance-based awards, are granted. Stock-based compensation expense is recognized ratably over the requisite service period. For each stock option or restricted stock unit grant with vesting based on a combination of time, market or performance conditions, where vesting will occur if either condition is met, the related compensation costs are recognized over the shorter of the explicit service period or the derived service period. See Note 13 for additional information relating to stock-based compensation. |
Income Taxes | (m) Income Taxes We record income taxes using the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax basis, and operating loss and tax credit carryforwards. Our consolidated financial statements contain certain deferred tax assets which have arisen primarily as a result of operating losses, as well as other temporary differences between financial and tax basis accounting. We establish a valuation allowance if the likelihood of realization of the deferred tax assets is reduced based on an evaluation of objective verifiable evidence. Significant management judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against those net deferred tax assets. We evaluate the weight of all available evidence to determine whether it is more likely than not that some portion or all of the net deferred income tax assets will not be realized. Income taxes include the largest amount of tax benefit for an uncertain tax position that is more likely than not to be sustained upon audit based on the technical merits of the tax position. Settlements with tax authorities, the expiration of statutes of limitations for particular tax positions, or obtaining new information on particular tax positions may cause a change to the effective tax rate. We recognize accrued interest related to unrecognized tax benefits as interest expense and penalties within operating expense in the consolidated statements of operations. See Note 18 for additional information relating to income taxes. |
Computation of Net Income per Share | (n) Computation of Net Income per Share Basic earnings per share is computed by dividing income available to common stockholders (the numerator) by the weighted-average number of common shares outstanding (the denominator) for the period. The computation of diluted earnings per share is similar to basic earnings per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common shares had been issued, calculated using the treasury stock method. The components of net income per share are as follows: Year ended December 31, 2020 2019 2018 (in thousands, except per share data) Net income available to common stockholders $ 49,982 $ 17,034 $ 45,885 Weighted average common shares outstanding used in computing basic income per share 33,257 32,559 32,286 Incremental options and RSUs 871 1,269 1,716 Weighted average common shares used in computing diluted net income per share 34,128 33,828 34,002 Net income per share Basic $ 1.50 $ 0.52 $ 1.42 Diluted $ 1.46 $ 0.50 $ 1.35 Diluted weighted average common shares outstanding does not include restricted stock units outstanding to purchase 1,951 common equivalent shares and 232,844 common equivalent shares for the periods ended December 31, 2020 and 2019, respectively, as their effect would have been anti-dilutive. |
