In addition, we provide extensive worldwide aftermarket service and support, including spare parts, equipment upgrades and maintenance services to the semiconductor industry. Our product development and manufacturing activities currently occur primarily inthe United States although we are adding additional manufacturing capacity inSouth Korea that should come online by year end 2021. Our equipment and service products are highly technical and are sold through a direct sales force inthe United States ,Europe andAsia . Consolidation and partnering within the semiconductor manufacturing industry has resulted in a small number of customers representing a substantial portion of our business. Our ten largest customers accounted for 71.1% of total revenue for the six months endedJune 30, 2021 . In the first half of 2021, we delivered strong financial performance driven by strong semiconductor industry fundamentals and an increasing demand for our Purion products, especially in the high growth power device market. The rapid acceleration of the electrification of the automotive industry is creating substantial demand for power devices and image sensors, which is driving sustainable growth for the Purion product extensions specifically developed
for these markets. Despite the many difficult logistical challenges brought on by trade tensions betweenthe United States andChina and COVID-19, we are continuing to work closely with our customers across market segments to provide them with the best ion implant solutions for their specific manufacturing challenges. InDecember 2020 , theUnited States Commerce Department placed one of our major Chinese customers, Semiconductor Manufacturing International Corporation ("SMIC"), on theU.S. export controls Entity List. As a result of the Entity List classification, we are required to obtain export controls licenses for allU.S. shipments to this customer. Although we have begun receiving these licenses, this situation did delay some shipments to this customer in the first half of 2021. Critical Accounting Estimates
Management's discussion and analysis of our financial condition and results of operations included herein and in our Annual Report on Form 10-K for the year endedDecember 31, 2020 are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted inthe United States . The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and assumptions. Management's estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. 19 Table of Contents
Management has not identified any need to make any material change in, and has not changed, any of our critical accounting estimates and judgments as described in Management's Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year endedDecember 31, 2020 .

Product Product revenue, which includes systems sales, sales of spare parts, product upgrades and used systems was$140.2 million , or 95.2% of revenue during the three months endedJune 30, 2021 , compared with$117.2 million , or 95.3% of revenue for the three months endedJune 30, 2020 . The$23.0 million increase in product revenue for the three-month period endingJune 30, 2021 , in comparison to the same period in 2020, was primarily driven by an increase in the number of systems sold.
A portion of our revenue from systems sales is deferred until installation and other services related to future performance obligations are performed. The total amount of deferred revenue atJune 30, 2021 andDecember 31, 2020 was$35.5 million and$23.1 million , respectively. The increase in deferred revenue was primarily due to customer prepayments for systems. Services Services revenue, which includes the labor component of maintenance and service contracts and fees for service hours provided by on-site service personnel, was$7.1 million , or 4.8% of revenue for the three months endedJune 30, 2021 , compared with$5.8 million , or 4.7% of revenue for the three months endedJune 30, 2020 . Although services revenue typically increases with the expansion of the installed base of systems, it can fluctuate from period to period based on capacity utilization at customers' manufacturing facilities, which affects
the need for equipment service.
Six months endedJune 30, 2021 Compared with Six months endedJune 30, 2020
Product Product revenue was$266.8 million , or 95.3% of revenue during the six months endedJune 30, 2021 , compared with$229.3 million , or 94.8% of revenue for the six months endedJune 30, 2020 . The$37.4 million increase in product revenue for the six-month period endingJune 30, 2021 , in comparison to the same period in 2020, was primarily driven by an increase in the number of systems sold and to a lesser extent revenue increases in spare parts, product upgrades and used systems.

Revenue Categories used by Management
In addition to the line item revenue categories discussed above, management also regularly disaggregates revenue in the following categories, which it finds relevant and useful:
Ion implant revenue separate from revenue from legacy non-ion implant product
? lines, given that ion implantation systems are the primary driver of our growth
and strategic objectives;
? Systems and Aftermarket revenues, in which "Aftermarket" is:
A. The portion of Product revenue relating to spare parts, product upgrades and
used equipment, combined with
B. Services revenue, which is the labor component of Aftermarket revenues
(Aftermarket purchases reflect current fab utilization as opposed to Systems purchases which reflect capital investment decisions by our customers, which have differing economic drivers); 21 Table of Contents
Revenue by geographic regions, since economic factors impacting customer
? purchasing decisions may vary by geographic region; and
Revenue by our customer market segments, since they can be subject to different
economic drivers at different periods of time, impacting a customer's
? likelihood of purchasing capital equipment during any particular period.
Currently, management references three customer market segments: memory, mature
technology processes and leading edge foundry and logic.
The ion implant and Aftermarket revenue categories for recent periods are discussed below.

Ion Implant Included in total revenue of$147.3 million during the three months endedJune 30, 2021 is revenue from sales of ion implant products and services of$142.9 million , or 97.0% of total revenue, compared with$118.7 million , or 96.6%, of total revenue for the three months endedJune 30, 2020 . The remaining$4.4 million of revenue for the three months endedJune 30, 2021 was non-ion implant parts and services. Aftermarket Included in total revenue of$147.3 million during the three months endedJune 30, 2021 is revenue from our Aftermarket business of$47.1 million , compared to$46.2 million for the three months endedJune 30, 2020 . The remaining$100.2 million of revenue for the three months endedJune 30, 2021 was from system sales. Aftermarket revenue fluctuates from period to period based on capacity utilization at customers' manufacturing facilities, which affects the sale of spare parts and demand for equipment service. Aftermarket revenue can also fluctuate from period to period based on the demand for system upgrades or
used equipment.

Other expense was$1.2 million for the three months endedJune 30, 2021 , compared with$0.8 million for the three months endedJune 30, 2020 . The increase in other expense was primarily due to an increase in foreign currency exchange losses. Other expense was$3.4 million for the six months endedJune 30, 2021 , compared with$2.2 million for the six months endedJune 30, 2020 . The increase in other expense was primarily due to an increase in foreign currency exchange losses of$0.6 million as well as a reduction of$0.5 million in interest income when compared to the six-month period endedJune 30, 2020 . During the six-month periods endedJune 30, 2021 and 2020, we had no significant off-balance-sheet risk such as exchange contracts, option contracts or other hedging arrangements.

The$1.5 million increase was primarily due to a$7.2 million increase in pretax income. Income tax expense was$5.6 million during the six months endedJune 30, 2021 , compared to$3.3 million for the six months endedJune 30, 2020 . The$2.3 million increase was primarily due to a$13.1 million increase in pretax income. The effective tax rate for the three and six months endedJune 30, 2021 and 2020, respectively, was less than theU.S. statutory rate of 21% due to favorable discrete items related to equity compensation in those periods as well as Federal research and development tax credits that reduce the annual tax rate. We had$51.4 million and$57.9 million of net deferred tax assets worldwide relating to net operating loss carryforwards, tax credit carryforwards and other temporary differences, as ofJune 30, 2021 andDecember 31, 2020 , respectively. These deferred tax assets are available to reduce income taxes in future years. We have a$9.1 million valuation allowance in theU.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 tax assets. If future operating results of the Company within theU.S. or these foreign jurisdictions are significantly less than our expectations, it is reasonably possible that we would be required to record an additional valuation allowance on our deferred tax assets in the future. .
Liquidity and Capital Resources
We had$219.7 million in unrestricted cash and cash equivalents atJune 30, 2021 , in addition to$0.8 million in restricted cash. Management believes that maintaining a strong cash balance is necessary to provide funding for potential ramps in our business which can require significant cash investment to meet sudden demand. Additionally, we are using cash in our 2021 stock repurchase program and are considering both organic and inorganic opportunities to drive future growth, for which cash resources will be necessary. Our liquidity is affected by many factors. Some of these relate specifically to the operations of our business, for example, the rate of sale of our products, and others relate to the uncertainties of global economic conditions, including the availability of credit and the condition of the overall semiconductor equipment industry. Our established cost structure, other than cost of goods sold, does not vary significantly with changes in volume. We experience fluctuations in operating results and cash flows depending on these factors. Stock repurchases, as discussed below, also reduce our cash balances. 26 Table of Contents During the six months endedJune 30, 2021 , we generated$45.9 million of cash related to operating activities. During the six months endedJune 30, 2020 , we generated$56.6 million of cash related to operating activities. Investing activities for the six months endedJune 30, 2021 and 2020 resulted in cash outflows of$2.4 million and$3.0 million , respectively, used for capital expenditures. Financing activities for the six months endedJune 30, 2021 resulted in a cash usage of$28.3 million . During the first six months of 2021,$25.0 million in cash was used to repurchase our common stock and$6.5 million was used for payments to government tax authorities for income tax withholding on employee compensation arising from the vesting of RSUs, where shares are withheld by the Company, as well as$0.4 million relating to the reduction of the liability under the finance lease of our corporate headquarters. These amounts were partially offset by$3.6 million of proceeds from the exercise of stock options and purchase of shares under our 2020 ESPP during the first six months of 2021. In comparison, financing activities for the six months endedJune 30, 2020 resulted in cash usage of$3.7 million ,$7.5 million of which related to the repurchase of our common stock and$3.9 million related to payments made to government tax authorities for income tax withholding on employee compensation arising from the vesting of RSUs, as well as$0.1 million relating to the reduction of our financing lease liability. These amounts were partially offset by$7.8 million of proceeds related to the exercise of stock options and purchase of shares under our prior employee stock purchase plan during the
first six months of 2020.
Under the rules of theU.S. Securities and Exchange Commission (the "SEC"), we qualify as a "well-known seasoned issuer," which allows us to file shelf registration statements to register an unspecified amount of securities that are effective upon filing. OnMay 29, 2020 , we filed such a shelf registration statement with theSEC for the issuance of an unspecified amount of common stock, preferred stock, various series of debt securities and/or warrants to purchase any of such securities, either individually or in units, from time to time at prices and on terms to be determined at the time of any such offering. This registration statement was effective upon filing and will remain in effect for up to three years from filing, prior to which time we may file another shelf registration statement to maintain the availability of this financing option. OnJuly 31, 2020 , we entered into a Senior Secured Credit Facilities Credit Agreement (the "Credit Agreement") withSilicon Valley Bank . 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 onJuly 31, 2023 . As ofJune 30, 2021 , 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 reduces the funds available for borrowing under the credit line. We have no immediate plans to borrow under the Credit Agreement, but we will use the facility for letters of credit, for ongoing working capital needs and to fund general corporate purposes, as desired. We entered into a First Amendment to the Credit Agreement withSilicon Valley Bank inMarch 2021 to (i) align the covenants with our 2021 stock repurchase program, and (ii) establish terms to transition from a Eurodollar based interest rate option to an interest rate benchmark using a secured overnight financing rate (known as "SOFR") published by theFederal Reserve Bank of New York . We believe that based on our current market, revenue, expense and cash flow forecasts, our existing cash, cash equivalents and equity and debt financing capacity will be sufficient to satisfy our anticipated cash requirements for the short and long-term.
Commitments and Contingencies
Significant commitments and contingencies atJune 30, 2021 are consistent with those discussed in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations," and Note 16 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year endedDecember 31, 2020 . 27 Table of Contents
