SPS Commerce is a leading provider of cloud-based supply chain management solutions that make it easier for retailers, suppliers, grocers, distributors, and logistics firms to orchestrate the management of item data, order fulfillment, inventory control and sales analytics across all channels. For many businesses, implementing and maintaining a suite of supply chain management capabilities is resource-intensive and not a core competency. The solutions offered by SPS Commerce eliminate the need for on-premise software and support staff by taking on that capability on the customer’s behalf. These solutions also enable our customers to increase their supply cycle agility, optimize their inventory levels and sell-through, reduce operational costs and gain increased visibility into customer orders, helping ensure that suppliers, grocers, distributors, and logistics firms can satisfy retailer requirements.

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of SPS Commerce, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements.

This interim financial information has been prepared under the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by GAAP. We have included all normal recurring adjustments considered necessary to provide a fair presentation of our financial position, results of operations, stockholders’ equity, and cash flows for the interim periods shown. Operating results for these interim periods are not necessarily indicative of the results to be expected for the full year. For further information, refer to the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the Securities and Exchange Commission (“SEC”).

In December 2020, we acquired all of the outstanding equity ownership interests of D Masons Software, LLC (“Data Masons”). As of December 31, 2020 and ~~March 31,~~June 30, 2021, the purchase accounting for the acquisition is not finalized. Provisional amounts are primarily related to intangible assets ~~net working capital,~~ and tax positions. We expect to finalize the allocation of the purchase price within the one-year measurement period following the acquisition. During the three months ended March 31, 2021, the only change in the purchase accounting was a $0.3 million reduction of amounts due from the seller as part of the initial net working capital adjustment and a corresponding increase to goodwill. ~~Subsequent to March 31,~~During the three months ended June 30, 2021, there was no change in the purchase accounting and the net working capital amount was finalized and collected without change from the ~~amounts~~amount recorded at March 31, 2021.

Preparing financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

For the ~~three~~six months ended ~~March 31,~~June 30, 2021, there were no newly adopted accounting pronouncements. As of ~~March 31,~~June 30, 2021, there are no recently issued but not yet adopted accounting pronouncements that are expected to materially impact our consolidated financial statements.

There were no material changes in our significant accounting policies during the ~~three~~six months ended ~~March 31,~~June 30, 2021. See Note A to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the SEC, for additional information regarding our significant accounting policies.

Revenues are recognized when our services are made available to our customers, in an amount that reflects the consideration we are contractually and legally entitled to in exchange for those services.

Recurring revenues consist of recurring subscriptions from customers that utilize our Fulfillment, Analytics, and Other cloud-based supply chain management solutions. Revenue for these solutions is generally recognized on a ratable basis over the contract term beginning on the date that our service is made available to the customer. Our contracts with our recurring revenue customers are recurring in nature, ranging from monthly to annual, and generally allow the customer to cancel the contract for any reason with 30 to 90 days’ notice. Timing of billings varies by customer and by contract type and are either in advance or within 30 days of the service being performed.

The deferred revenue liability for recurring revenue contracts are for one year or less and recognized on a ratable basis over the contract term. We have applied the optional exemption to not disclose information about the remaining performance obligations for contracts which have original durations of one year or less.

One-time revenues consist of set-up fees from customers and miscellaneous one-time fees.

Set-up fees are specific for each connection a customer has with a trading partner and many of our customers have connections with numerous trading partners. Set-up fees related to our cloud-based supply chain management solutions are nonrefundable upfront fees that are necessary for our customers to utilize our cloud-based services. These set-up fees do not provide any standalone value to our customers.

Certain contracts contain set-up fees that constitute a material renewal option right. This material right provides customers a significant future incentive that would not otherwise be available to them unless they entered into the contract, as the set-up fees will not be incurred again upon contract renewal.

For our Fulfillment solution, we have determined that the set-up fees and related costs represent a material renewal option right to our customers as they will not be incurred again upon renewal. These set-up fees and related costs are deferred and recognized ratably over two years, which is the estimated period for which a material right is present for our customers.

For our Analytics solution, we have determined that the set-up fees do not represent a material customer renewal right and, as such, are deferred and recognized ratably over the estimated initial contract term, which is generally one year.

The table below presents the activity of the portion of the deferred revenue liability relating to set-up fees:

The entire balance of set-up fees will be recognized within two years and, as such, current amounts will be recognized in the next 1-12 months and long-term amounts will be recognized in the next 13-24 months.

Miscellaneous one-time fees consist of professional services and testing and certification. The deferred revenue liability for these one-time fees are for one year or less and recognized at the time service is provided. We have applied the optional exemption to not disclose information about the remaining performance obligations for contracts which have original durations of one year or less.

We invest primarily in money market funds, certificates of deposit, highly liquid debt instruments of the United States (“U.S.”) government and U.S. corporate debt securities. All investments with remaining maturities of less than one year from the balance sheet date are classified as short-term investments. Investments with remaining maturities of more than one year from the balance sheet date are classified as long-term investments. Our short-term marketable securities are classified as available-for-sale. We intend to hold marketable securities until maturity; however, we may sell these securities at any time for use in current operations or for other purposes.

Our marketable securities are carried at fair value and unrealized gains and losses on these investments, net of taxes, are included in accumulated other comprehensive loss in the condensed consolidated balance sheets. Realized gains or losses are included in other ~~expense,~~income (expense), net in the condensed consolidated statements of comprehensive income. Certain securities accrue interest that is included in other ~~expense,~~income (expense), net. The unrealized gains (losses) noted below are exclusive of previously recognized interest income. When a determination has been made that the fair value of a marketable security is below its amortized cost basis, the portion of the unrealized loss that corresponds to a credit-related factor is realized through a credit allowance on the marketable security and the equivalent expense is realized in other ~~expense,~~income (expense), net in the condensed consolidated statements of comprehensive income.

We measure certain financial assets at fair value on a recurring basis based on a fair value hierarchy that requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring 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 three levels of inputs that may be used to measure fair value are:

~~We obtain the fair values of our Level 2 available-for-sale securities from a professional pricing service.~~

For the contingent consideration liability, related to the Data Masons acquisition, we are required to pay the former owners of Data Masons $1.9 million in the event the Paycheck Protection Program (“PPP”) Loan (“PPP Loan”) acquired in the acquisition is forgiven in full. In November 2020, Data Masons applied for full forgiveness of the PPP Loan. At March 31, 2021, although unknown, we determined that it is probable that Data Masons’ use of the PPP Loan proceeds will meet the conditions for full forgiveness under the PPP. Subsequent to March 31, 2021, the Small Business Administration approved the full forgiveness of the PPP Loan and as such, the payment of the $1.9 million contingent liability is anticipated to be made in the three months ending June 30, 2021.

The following table presents information about our financial assets and liabilities that are measured at fair value on a recurring basis and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value:

~~There~~For the contingent consideration liability, related to the Data Masons acquisition, we were ~~0 transfers~~required to pay the former owners of Data Masons $1.9 million in ~~or out of our Level 1, 2, or 3 assets or liabilities during~~the event the Paycheck Protection Program (“PPP”) Loan (“PPP Loan”) acquired in the acquisition was forgiven in full. In the three months ended ~~March 31, 2021.~~ June 30, 2021, the Small Business Administration approved the full forgiveness of the PPP Loan and, accordingly, the payment of the $1.9 million contingent liability was made.

We measure certain assets and liabilities at fair value on a nonrecurring basis. Assets that are measured at fair value on a nonrecurring basis include long-lived assets, goodwill, and indefinite-lived intangible assets, which would generally be recorded at fair value as a result of an impairment charge. Assets acquired and liabilities assumed as part of business combinations are measured at fair value.

The carrying amounts of our short-term financial instruments, including cash and cash equivalents, accounts receivable, and accounts payable, when applicable, approximate their respective fair values due to their short-term nature.

The allowance for credit losses activity, included in accounts receivable, net, was as follows:

On November 2, 2019, our board of directors authorized a program to repurchase up to $50 million of common stock. Under the program, purchases may be made from time to time in the open market over two years. For the three months ended ~~March 31,~~June 30, 2021, we ~~did 0t repurchase any shares.~~repurchased 63,515 shares at a cost of $6.4 million. As of ~~March 31,~~June 30, 2021, ~~$31.1~~$24.6 million of the share repurchase program was available for future share repurchases.

Our equity compensation plans provide for the grant of incentive and nonqualified stock options, as well as other stock-based awards including performance share units (“PSUs”), restricted stock awards (“RSAs”), restricted stock units (“RSUs”), and deferred stock units (“DSUs”). We also have an employee stock purchase plan (“ESPP”). We recognize stock-based compensation expense based on grant date award fair value. This cost is recognized over the period for which the employee is required to provide service in exchange for the award or the award performance period, except for expense relating to retirement-eligible employees that have not given their required notice, which is recognized on a pro-rata basis over the notice period prior to retirement. At ~~March 31,~~June 30, 2021, there were 13.6 million shares available for grant under approved equity compensation plans.

Stock-based compensation expense was allocated in the condensed consolidated statements of comprehensive income as follows:

As of ~~March 31,~~June 30, 2021, there was ~~$40.6~~$37.6 million of unrecognized stock-based compensation expense under our equity compensation plans, which is expected to be recognized on a straight-line basis over a weighted average period of ~~2.8~~2.6 years.

Of the total outstanding options at ~~March 31,~~June 30, 2021, 0.7 million were exercisable. The outstanding and exercisable options had a weighted average exercise price of ~~$33.82~~$34.39 per share and a weighted average remaining contractual life of ~~3.4~~3.2 years.

The weighted average grant date fair value of options granted during the ~~first three~~six months ofended June 30, 2021 was ~~$31.16~~$30.96 per share. This was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:

Performance Share Units, Restricted Stock Units and Awards, and Deferred Stock Units

In each of the quarters ended March 31, 2021, 2020, 2019, and 2018 we granted PSU awards with a target performance level. These awards are earned based upon the Company’s total shareholder return as compared to an indexed total shareholder return over the course of a fiscal based three-year performance period, starting in the year of grant. Awards vest in the quarter following the conclusion of the performance period. In the three months ended March 31, 2021, PSU awards granted in 2018 vested at the maximum performance level and 0.1 million shares of common stock were issued.

A total of ~~1.9~~1.8 million shares of common stock are reserved for issuance under the ESPP as of ~~March 31,~~June 30, 2021.

The fair value was estimated based on the market price of our common stock at the beginning of the offering period using the Black-Scholes option pricing model with the following assumptions:

We record our interim provision for income taxes by applying our estimated annual effective tax rate to our year-to-date pretax income and adjust the provision for discrete tax items recorded in the period. Differences between our effective tax rate and statutory tax rates are primarily due to the impact of permanently non-deductible expenses partially offset by the federal research and development credits and tax benefits associated with foreign-derived intangible income. Additionally, excess tax benefits generated upon settlement or exercise of stock awards are recognized as a reduction to income tax expense as a discrete tax item in the quarter that the event occurs creating potentially significant fluctuation in tax expense by quarter and by year. Our provisions for income taxes includes current federal, state, and foreign income tax expense, as well as deferred tax expense.

As of ~~March 31,~~June 30, 2021, we did 0t have any unrecognized tax benefits, accrued interest, or tax penalties.

Effective January 1, 2021, all realized gains or losses and interest income on our investments are included in investment income. Previously, realized gains and losses were included in other income (expense), net and interest income was included in interest income, net. Additionally, realized gains or losses from foreign currency on cash and investments held were previously included in other income (expense), net. Amounts for the three and six months ended ~~March 31,~~June 30, 2020 have been reclassified to be consistent with the classifications for the three and six months ended ~~March 31,~~June 30, 2021.

Basic net income per share has been computed using the weighted average number of shares of common stock outstanding during each period. Diluted net income per share also includes the impact of our outstanding potential common shares, including options, PSUs, RSUs, RSAs, and DSUs. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net income per share.

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements regarding us, our business prospects and our results of operations are subject to certain risks and uncertainties posed by many factors and events, many of which may be amplified by the coronavirus (COVID-19) pandemic, that could cause our actual business, prospects, and results of operations to differ materially from those that may be anticipated by such forward-looking statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this report. In some cases, you can identify forward-looking statements by the following words: “anticipate,” “assumes,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “ongoing,” “plan,” “potential,” “predict,” “project,” “should,” “will,” “would,” or the negative of these terms or other comparable terminology, although not all forward-looking statements contain these words. Similarly, statements that describe our future plans, objectives or goals are also forward-looking. Forward-looking statements may also be made from time to time in oral presentations, including telephone conferences and/or webcasts open to the public. Shareholders, potential investors and others are cautioned that all forward-looking statements involve risks and uncertainties that could cause results in future periods to differ materially from those anticipated by some of the statements made in this report, including the risks and uncertainties described under the heading “Risk Factors” appearing in our Annual Report on Form 10-K for the year ended December 31, 2020, as may be updated in our subsequent Quarterly Reports on Form 10-Q from time to time, including the updates in this Quarterly Report on Form 10-Q. We expressly disclaim any intent or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. Readers are urged to carefully review and consider the various disclosures made by us in this report and in our other reports filed with the SEC that advise interested parties of the risks and factors that may affect our business.

SPS Commerce is a leading provider of cloud-based solutions that make it easier for retailers, suppliers, grocers, distributors, and logistics firms to orchestrate the management of item data, order fulfillment, inventory control and sales analytics across all channels. The solutions offered by SPS Commerce eliminate the need for on-premise software and support staff by taking on that capability on the customer’s behalf. We derive the majority of our revenues from numerous monthly recurring subscriptions from businesses that utilize our solutions.

We plan to continue to grow our business by further penetrating the supply chain management market, increasing revenues from our customers as their businesses grow, expanding our distribution channels, expanding our international presence and, from time to time, developing new solutions and applications. We also intend to selectively pursue acquisitions that will add customers, allow us to expand into new regions, or allow us to offer new functionalities.

For the three months ended ~~March 31,~~June 30, 2021, our revenues were ~~$90.1~~$94.5 million, an increase of ~~21%~~25% from the comparable period in 2020, and represented our ~~81st~~82nd consecutive quarter of increased revenues. Total operating expenses increased ~~21%~~23% for the same period in 2021 from 2020.

We have several key financial terms and metrics, including annualized average recurring revenues per recurring revenue customer. ~~During the three months ended March 31,~~Beginning in 2021, we added Adjusted EBITDA Margin as a financial metric. There were no additional changes in the definitions of our key financial terms and metrics, which are discussed in more detail under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the SEC.

To supplement our financial statements, we ~~also~~ provide investors with Adjusted EBITDA, Adjusted EBITDA Margin, and non-GAAP income per share, all of which are non-GAAP financial measures. We believe that these non-GAAP measures provide useful information to our management, board of directors, and investors regarding certain financial and business trends relating to our financial condition and results of operations. Our management uses these non-GAAP measures to compare the Company’s performance to that of prior periods for trend analyses and planning purposes. Adjusted EBITDA is also used for purposes of determining executive and senior management incentive compensation. ~~These measures are presented to our board of directors.~~

These non-GAAP measures should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP. These non-GAAP financial measures exclude significant expenses and income that are required by GAAP to be recorded in our financial statements and are subject to inherent limitations. Investors should review the reconciliations of non-GAAP financial measures to the comparable GAAP financial measures that are included in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

This discussion of our financial condition and results of operations is based upon our condensed consolidated financial statements, which are prepared in accordance with GAAP and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The preparation of these financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and related disclosures. On an ongoing basis, we evaluate our estimates and assumptions. We base our estimates of the carrying value of certain assets and liabilities on historical experience and on various other assumptions that we believe to be reasonable. Our actual results may differ from these estimates under different assumptions or conditions.

A critical accounting policy is one that is both material to the presentation of our financial statements and requires us to make difficult, subjective, or complex judgments relating to uncertain matters that could have a material effect on our financial condition and results of operations. Accordingly, we believe that our policies for revenue recognition, internal-use software, and business combinations are the most critical to fully understand and evaluate our financial condition and results of operations.

During the ~~three~~six months ended ~~March 31, 2021,~~June 30, 2020, there were no changes in our critical accounting policies or estimates. See Note A to our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the SEC, for additional information regarding our accounting policies.

Revenues - The increase in revenues resulted from two primary factors: the increase in recurring revenue customers and an increase in annualized average recurring revenues per recurring revenue customer, which we also refer to as wallet share.

Recurring revenues from recurring revenue customers accounted for 92% and 94% of our total revenues for the three months ended ~~March 31,~~June 30, 2021 and 2020, respectively. We anticipate that the number of recurring revenue customers and wallet share will increase as we increase the number of solutions we offer and increase the penetration of those solutions across our customer base.

Cost of Revenues - The increase in cost of revenues for the three months ended ~~March 31,~~June 30, 2021 was primarily due to increased headcount which resulted in an increase of ~~$5.3~~$6.1 million in personnel-related costs and an increase of ~~$0.7~~$0.8 million in stock-based compensation. Additionally, as we continued to invest in the infrastructure supporting our platform, depreciation expense increased by $0.4 million.

Sales and Marketing Expenses - The increase in sales and marketing expense for the three months ended ~~March 31,~~June 30, 2021 was primarily due to ~~increased headcount which resulted in~~ an increase of ~~$1.1 million in personnel-related costs and an increase of $0.6 million in stock-based compensation. Additionally, the increase was due to an increase of $0.9~~$1.4 million in variable compensation earned by sales personnel and referral partners. Additionally, an increase of $1.2 million in personnel-related costs and an increase of $0.7 million in stock-based compensation contributed to the overall increase.

Research and Development Expenses - The increase in research and development expense for the three months ended ~~March 31,~~June 30, 2021 was primarily due to increased headcount which resulted in an increase in personnel costs of $0.9 million and an increase in software subscription expense of ~~$0.2~~$0.3 million.

General and Administrative Expenses - The increase in general and administrative expense for the three months ended ~~March 31,~~June 30, 2021 was driven by ~~an increase~~increases in personnel-related costs of $1.5 million and stock-based compensation of ~~$1.3~~$0.7 million. Additionally, ~~increases~~an increase of ~~$0.6~~$0.4 million in ~~charitable donations and $0.5 million in personal costs~~software subscriptions contributed to the overall increase.

Amortization of Intangible Assets - The increase in amortization of intangible assets was driven by the amortization of the acquired intangible assets related to Data ~~Masons.~~Masons, which we acquired in December 2020.

Other ~~Expense,~~Income (Expense), Net - ~~Total~~The change in other ~~expenses decreased~~expense, net of $0.4 million, compared to the other income, net of $1.5 million in the prior year period, was primarily due to ~~better investment performance as well as smaller~~larger foreign currency exchange losses.

Income Tax Expense - The increase in income tax expense was primarily due to an increase in nondeductible executive compensation as well as a decrease in both the discrete tax benefits from stock activity ~~in addition to an increase in pre-tax income.~~and research and development credits. Excess tax benefits generated upon the settlement or exercise of stock awards are recognized as a reduction to income tax expense and, as a result, we expect that our annual effective income tax rate will fluctuate.

Adjusted EBITDA Margin.Adjusted EBITDA Margin, which is a non-GAAP measure of financial performance, consists of Adjusted EBITDA divided by revenue. Margin, the comparable GAAP measure of financial performance, consists of net income divided by revenue. The following table provides a comparison of Margin to Adjusted EBITDA Margin:

Non-GAAP Income per Share.Non-GAAP income per share, which is a non-GAAP measure of financial performance, consists of net income adjusted for stock-based compensation expense, amortization expense related to intangible assets, realized gain or loss from foreign currency on cash and investments held, and other adjustments as necessary for a fair presentation, divided by the weighted average number of shares of common stock outstanding during each period. Other adjustments include the expense impact of the disposal of certain capitalized internally developed software and cloud hosting arrangement implementation costs. To quantify the tax effects, we recalculated income tax expense excluding the direct book and tax effects of the specific items constituting the non-GAAP adjustments. The difference between this recalculated income tax expense and GAAP income tax expense is presented as the income tax effect of the non-GAAP adjustments.

The following table provides a reconciliation of net income to non-GAAP income per share:

The following table presents our results of operations for the periods indicated:

Recurring revenues from recurring revenue customers accounted for 92% and 94% of our total revenues for the six months ended June 30, 2021 and 2020, respectively. We anticipate that the number of recurring revenue customers and wallet share will increase as we increase the number of solutions we offer and increase the penetration of those solutions across our customer base.

Cost of Revenues -The increase in cost of revenues for the six months ended June 30, 2021 was primarily due to increased headcount which resulted in an increase of $11.4 million in personnel-related costs and an increase of $1.5 million in stock-based compensation. Additionally, as we continued to invest in the infrastructure supporting our platform, depreciation expense increased by $0.8 million.

Sales and Marketing Expenses -The increase in sales and marketing expense for the six months ended June 30, 2021 was primarily due to an increase of $2.4 million in variable compensation earned by sales personnel and referral partners. Additionally, an increase of $2.4 million in personnel-related costs and an increase of $1.4 million in stock-based compensation contributed to the overall increase.

Research and Development Expenses - The increase in research and development expense for the six months ended June 30, 2021 was primarily due to increased headcount which resulted in an increase in personnel costs of $1.8 million and an increase in software subscription expense of $0.6 million.

General and Administrative Expenses - The increase in general and administrative expense for the six months ended June 30, 2021 was driven by increases in personnel-related costs of $2.0 million and stock-based compensation of $2.0 million. Additionally, an increase of $0.7 million in charitable contributions led to the overall increase.

Amortization of Intangible Assets -The increase in amortization of intangible assets was driven by the amortization of the acquired intangible assets related to Data Masons, which we acquired in December 2020.

Other Income (Expense), Net -The change in other expense, net of $0.7 million, compared to the other income, net of $0.8 million in the prior year period, was primarily due to larger foreign currency exchange losses and decreased investment income.

Income Tax Expense -The increase in income tax expense was primarily due to an increase in nondeductible executive compensation as well as a decrease in both the discrete tax benefits from stock activity and research and development credits. Excess tax benefits generated upon the settlement or exercise of stock awards are recognized as a reduction to income tax expense and, as a result, we expect that our annual effective income tax rate will fluctuate.

Adjusted EBITDA -Adjusted EBITDA, which is a non-GAAP measure of financial performance, consists of net income adjusted for depreciation and amortization expense, investment income or loss, realized gain or loss from foreign currency on cash and investments held, income tax expense, stock-based compensation expense, and other adjustments as necessary for a fair presentation. Other adjustments include the expense impact from the disposals of certain capitalized internally developed software and cloud hosting arrangement implementation costs and an earn-out liability fair value ~~adjustment for the EDIAdmin earn-out liability. As~~adjustment. Additionally, as part of executing a lease amendment, we incurred accelerated depreciation, included within Depreciation and amortization of property and equipment, and offsetting accelerated tenant improvement benefit, which is included within Other.

At ~~March 31,~~June 30, 2021, our principal sources of liquidity were cash and cash equivalents, certificates of deposit and short-term investments totaling ~~$208.4~~$233.4 million and accounts receivable, net of provision for credit losses, of ~~$35.3~~$37.9 million. Certificates of deposit and investments are invested in accordance with our investment policy, with a goal of maintaining liquidity and capital preservation. Our cash equivalents and short-term investments are held in highly liquid money market funds, commercial paper, federal agency securities and corporate debt securities.

The ~~below table summarizes the~~summary of activity within the condensed consolidated statements of cash ~~flows:~~flows was as follows:

	Three Months Ended						Six Months Ended
	March 31,						June 30,
(In thousands)	2021			2020			2021			2020
Net cash provided by operating activities	$	21,605		$	14,667		$	54,658		$	36,795
Net cash used in investing activities		(4,802	)		(550	)		(17,772	)		(32,490	)
Net cash provided by (used in) financing activities		2,743			(8,918	)
Net cash used in financing activities								(2,276	)		(8,662	)

The increase in cash provided by operating activities was primarily driven by the changes in assets and liabilities, principally the increases in deferred revenue and accrued compensation balances. Additionally, business expansion ~~which~~ resulted in increased depreciation and amortization of property and equipment, amortization of intangibles assets, and stock-based compensation ~~expense. Also, the increase was driven by continued business growth resulting in increased net income. Additionally, the changes in assets and liabilities~~expense that contributed to the ~~overall~~ increase.

The ~~increase~~decrease in net cash used in investing activities was primarily due to ~~an increase~~a decrease of net purchases of ~~investments as well as increased capital expenditures, due to our business growth and continued investment in our technology.~~investments.

The change in net cash ~~provided by (used in)~~used in financing activities was primarily due to the decreases in cash used for share repurchases and net proceeds from stock option exercises.

For information regarding the effect of foreign currency exchange rate changes, refer to the section entitled “Foreign Currency Exchange Risk,” included in Part I, Item 3, “Quantitative and Qualitative Disclosures About Market Risk” of this Quarterly Report on Form 10-Q.

Our future capital requirements may vary significantly from those now planned and will depend on many factors, including:

Historically, we have experienced increases in our expenditures consistent with the growth in our operations, and we anticipate that our expenditures will continue to increase as we expand our business.

We believe our cash, cash equivalents, investments and our cash flows from operations will be sufficient to meet our working capital and capital expenditure requirements for at least the next twelve months.

Inflation and changing prices did not have a material effect on our business during the ~~three~~six months ended ~~March 31,~~June 30, 2021 and we do not expect that inflation or changing prices will materially affect our business in the foreseeable future.

We do not have any off-balance sheet arrangements, investments in special purpose entities or undisclosed borrowings or debt. Additionally, we are not a party to any derivative contracts or synthetic leases.

Our contractual obligations and commercial commitments as of ~~March 31,~~June 30, 2021 are ~~summarized below:~~as follows:

	Payments Due by Period (in thousands)										Payments Due by Period (in thousands)
	Less Than						More Than				Less Than						More Than

The principal objectives of our investment activities are to preserve principal, provide liquidity and maximize income consistent with minimizing risk of material loss. We are exposed to market risk related to changes in interest rates. However, based on the nature and current level of our cash, cash equivalents, and investments, we believe there is no material risk of exposure. We do not enter into investments for trading or speculative purposes.

We did not have any variable interest rate outstanding debt as of ~~March 31,~~June 30, 2021. Therefore, we do not have any material risk to interest rate fluctuations.

We have revenue, expenses, assets, and liabilities that are denominated in currencies other than the U.S. dollar, primarily the Australian dollar and Canadian dollar. As of ~~March 31,~~June 30, 2021, we maintained approximately 7%6% of our total cash and cash equivalents outside of the U.S. in foreign currencies. We believe that a hypothetical 10% change in foreign currency exchange rates or an inability to access foreign funds would not affect our ability to meet our operational needs or result in a material foreign currency loss. As we expand internationally, our results of operations and cash flows may be impacted by changes in foreign currency exchange rates and would be adversely impacted when the U.S. dollar appreciates relative to other foreign currencies. We have not used any forward contracts or currency borrowings to hedge our exposure to foreign currency exchange risk, although we may do so in the future.

As of the end of the period covered by this Quarterly Report on Form 10-Q, our management has evaluated, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Disclosure controls and procedures are designed to ensure that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of ~~March 31,~~June 30, 2021.

In December 2020, we acquired the Data Masons business. Pursuant to the SEC’s general guidance that an assessment of a recently acquired business may be omitted from our scope for a period not to exceed one year from the date of acquisition, the scope of our most recent assessment did not include Data Masons. We are currently in the process of incorporating internal controls specific to Data Masons that we believe are appropriate and necessary to consolidate and report upon our financial results. Our assessment of the effectiveness of internal control over financial reporting as of December 31, 2021 will include Data Masons. As of and for the three and six months ended ~~March 31,~~June 30, 2021, excluding net intangible assets and goodwill, Data Masons represented approximately 3% of our consolidated assets and 6% of our consolidated revenues.

With the exception of the internal control related to integration activities associated with our acquisition of Data Masons, there were no changes in our internal control over financial reporting during the quarter ended ~~March 31,~~June 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We are not currently subject to any material legal proceedings. From time to time, we may be named as a defendant in legal actions or otherwise be subject to claims arising from our normal business activities. Any such actions, even those that lack merit, could result in the expenditure of significant financial and managerial resources. We believe that we have obtained adequate insurance coverage or rights to indemnification in connection with potential legal proceedings that may arise.

There have been no material changes in our risk factors from those disclosed under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the SEC.

Under a share repurchase program announced by our board of directors on November 2, 2019, ~~from time to time~~ we can repurchase up to a total of $50 million of our common stock in the open market through November 2, 2021. ~~We did not make any purchases in~~Our stock repurchase activity during the ~~first quarter of 2021. At March 31,~~three months ended June 30, 2021 ~~we had approximately $31.1 million remaining for shares that can be repurchased under the plan.~~ was as follows:

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
