FINANCIAL STATEMENTS

1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

8x8, Inc. (8x8 or the Company) is a leading provider of truly unified cloud communications. The Company's suite of products weaves together unified cloud communications, messaging, meeting and contact center solutions so today's organization can communicate at the speed of employee and customer expectations. 8x8 technology provides one unified management platform with one communication experience for employees and customers, as well as a real-time data analytics platform for constant learning and improvement. The Company is a provider of cloud-based, enterprise-class software solutions that transform the way businesses communicate and collaborate globally. The Company's integrated, "pure-cloud" offering combines global voice, conferencing, messaging and video with integrated workflows and big data analytics on a single platform to enable increased team productivity, better customer engagement and real-time insights into business performance.

BASIS OF PRESENTATION

The Company's fiscal year ends on March 31 of each calendar year. Each reference to a fiscal year in these notes to the consolidated financial statements refers to the fiscal year ended March 31 of the calendar year indicated (for example, fiscal 2018 refers to the fiscal year ended March 31, 2018).

The accompanying interim condensed consolidated financial statements are unaudited and have been prepared on substantially the same basis as our annual consolidated financial statements for the fiscal year ended March 31, 2017. In the opinion of the Company's management, these interim condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of our financial position, results of operations, and cash flows for the periods presented. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates.

The March 31, 2017 year-end condensed consolidated balance sheet data in this document were derived from audited consolidated financial statements and does not include all of the disclosures required by U.S. generally accepted accounting principles. These condensed consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements as of and for the fiscal year ended March 31, 2017 and notes thereto included in the Company's fiscal 2017 Annual Report on Form 10-K.

The results of operations and cash flows for the interim periods included in these condensed consolidated financial statements are not necessarily indicative of the results to be expected for any future period or the entire fiscal year.

RECLASSIFICATION

Certain software development costs capitalized in accordance with ASC 350-40, Internal Use Software (ASC 350-40), that were presented in other long-term assets in the Company's consolidated balance sheets as of March 31, 2017 are presented as property and equipment for the condensed consolidated balance sheet as of September 30, 2017. Assets in the amount of $7.7 million, net of accumulated amortization, have been reclassified in the balance sheet as of March 31, 2017 to conform to the current period presentation. The reclassification had no impact on the Company's previously reported consolidated net income (loss), cash flows, or basic or diluted net income per share amounts.

Certain amounts previously reported within the Company's condensed consolidated balance sheets and condensed consolidated statements of cash flows have been reclassified within each financial statement section to conform to the current period presentation. The reclassification had no impact on the Company's previously reported net loss, cash flows, or basic or diluted net loss per share amounts.

ACQUISITIONS

In May 2015, the Company entered into a share purchase agreement with the shareholders of DXI Limited for a purchase price of $22.5 million, consisting of $18.7 million in cash paid to the DXI shareholders at closing and $3.8 million in cash deposited into escrow to be held for two years as security against indemnity claims made by the Company after the closing date. During the fiscal quarter ended June 30, 2017, $1.4 million of the cash held in escrow was returned to the Company and the escrow fund was closed. Since the purchase accounting for the acquisition was finalized by March 31, 2016, the proceeds are realized as a gain and reported as other income in the consolidated statements of operations.

PRINCIPLES OF CONSOLIDATION

The condensed consolidated financial statements include the accounts of 8x8 and its subsidiaries. All material intercompany accounts and transactions have been eliminated.

SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies used in preparation of these condensed consolidated financial statements are disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2017 filed with the SEC on May 30, 2017, and there have been no changes to the Company's significant accounting policies during the six months ended September 30, 2017, except as described in the "Recently Adopted Accounting Pronouncements" section below.

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Stock-based Payment Accounting, which simplified certain aspects of accounting for stock-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The following is the impact of the adoption on the Company's consolidated financial statements:

• In recording stock-based compensation expense, the ASU allows companies to make a policy election as to whether they will include an estimate of awards expected to be forfeited or whether they will account for forfeitures as they occur. The Company has elected to continue to include an estimate of forfeitures in its stock-based compensation expense. Therefore, there was no impact to the Company's consolidated financial statements.

• The ASU requires that employee taxes paid when an employer withholds shares for tax-withholding purposes be reported as financing activities in the consolidated statements of cash flows. Previously, the Company already included these cash flows in financing activities. Therefore, the adoption of this provision had no impact.

• The ASU requires previously unrecognized excess tax benefits from stock-based compensation to be recognized on a modified retrospective basis. Unrecognized tax benefits result when a deduction for stock-based compensation does not reduce taxes payable. The impact to deferred tax assets is disclosed in Note 7.

• The ASU also requires excess tax benefits to be presented as an operating activity on the statement of cash flows rather than as a financing activity on either a retrospective or prospective basis. The Company has elected to apply this provision of the standard on a prospective basis.

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. Under this guidance, entities utilizing the first-in-first-out or average cost method should measure inventory at the lower of cost or net realizable value, where net realizable value is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The adoption of this standard did not have a material impact to the Company's consolidated financial statements.

RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, along with amendments issued in 2015 and 2016, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard will become effective for the Company on April 1, 2018 and permits the use of either the full retrospective or modified retrospective transition method. The Company has preliminarily selected the modified retrospective method as the transition method.

The Company is in the initial stages of the assessment of the impact of the new standard on the Company's accounting policies, processes and system requirements. The Company has assigned internal resources and engaged third-party service providers to assist with the assessment and implementation. The Company currently believes the most significant impact relates to:

7

• The allocation of consideration in a contract between product and service performance obligations; and
• The determination of performance obligations for professional services.

In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718) - Scope of Modification Accounting. The amendments in the update provide guidance on types of changes to the terms or conditions of share-based payment awards that would be required to apply modification accounting under ASC 718, Compensation-Stock Compensation. The amendments are effective for annual reporting periods beginning after December 15, 2017 with early adoption permitted. Upon adoption, the amendment is not expected to have a material impact to the consolidated financial statements.

Other Commitments, Indemnifications and Contingencies

There were no material changes in our other commitments under contractual obligations, indemnification and other contingencies since March 31, 2017.

Legal Proceedings

The Company, from time to time, is involved in various legal claims or litigation, including patent infringement claims that can arise in the normal course of the Company's operations. Pending or future litigation could be costly, could cause the diversion of management's attention and could upon resolution, have a material adverse effect on the Company's business, results of operations, financial condition and cash flows.

On August 22, 2017, the Company was named as a defendant in Venadium LLC v. 8x8 Inc., filed in the District of Delaware (Civil Action No. 1:17-cv-1176-LPS-CJB) along with five other defendants. Plaintiff Venadium LLC sued the Company for alleged patent infringement concerning alleged activities involving the Company's alleged methods for protecting computer programs. Based on the Company's subscription to certain patent risk management services, the Company settled the suit without needing to respond to the Complaint. The settlement amount was immaterial. On October 5, 2017, Plaintiff Venadium LLC filed a Notice of Voluntary Dismissal of Defendant (with prejudice) pursuant to Federal Rule of Civil Procedure 41(a)(1), thereby effecting formal dismissal of the suit without a Court Order.

On August 25, 2017, the Company was named as a defendant in Hublink, LLC v. 8x8 Inc., based on a Complaint filed in the District of Delaware (Civil Action No. 1:17-cv-1214-GMS) along with four other defendants. Plaintiff Hublink, LLC sued the Company for alleged patent infringement concerning alleged activities involving alleged implementations of the Company's videophone communications uses and/or offerings.

Performance Stock Units

During the three and six months ended September 30, 2017, the Company issued restricted performance stock units (PSUs) to a group of executives with vesting that is contingent on both market performance and continued service. These PSUs vest (1) 50% on September 19, 2019 and (2) 50% on September 19, 2020, in each case subject to the performance of the Company's common stock relative to the Russell 2000 Index (the benchmark) during the period from grant date through such vesting date. A 2x multiplier will be applied to the total shareholder returns (TSR) for each 1% of positive or negative relative TSR, and the number of shares earned will increase or decrease at the end of each respective performance measurement period by 2% of the target numbers. In the event 8x8's common stock performance is below negative 30% relative to the benchmark, no shares will be issued. These PSU grants are included in the restricted stock unit activity disclosure for the six months ended September 30, 2017.

To value these market-based PSUs under the Equity Compensation Plans, the Company used a Monte Carlo simulation model on the date of grant. Fair value determined using the Monte Carlo simulation model varies based on the assumptions used for the expected stock price volatility, the correlation coefficient between the Company and the NASDAQ Composite Index, risk free interest rates, and future dividend payments.

Stock Repurchases

In May 2017, the Company's board of directors authorized the Company to purchase $25.0 million of its common stock from time to time under the 2017 Repurchase Plan (the "2017 Plan"). The 2017 Plan expires when the maximum purchase amount is reached, or upon the earlier revocation or termination by the board of directors. The remaining amount available under the 2017 Plan at September 30, 2017 was approximately $10.9 million.

The stock repurchase activity as of September 30, 2017 is summarized as follows (in thousands):

			Weighted Average
	Shares		Price		Amount
	Repurchased		Per Share		Repurchased (1)
Repurchase of common stock under 2017 Repurchase Plan	1,064	$	13.23	$	14,081
Total	1,064			$	14,081
(1) Amount excludes commission fees.

The total purchase price of the common stock repurchased and retired was reflected as a reduction to consolidated stockholders' equity during the period of repurchase.

7. INCOME TAXES

The Company's effective tax rate was 86% and negative 125% for the three months ended September 30, 2017 and 2016, respectively. The effective tax rate is calculated by dividing the income tax provision by net income before income tax expense. The difference in the effective tax rate and the U.S. federal statutory rate of 34% in both periods was due primarily to the change in pretax profitability, geographic mix of profits and losses, and adoption of ASU 2016-09 effective April 1, 2017.

As described in Note 1, the Company adopted the updated accounting standard for share-based payment accounting in the first quarter of fiscal year 2018. As a result, the Company recorded deferred tax assets of approximately $17.6 million with a corresponding increase to retained earnings related to previously unrecognized excess tax benefits. For the six months ended September 30, 2017, the Company recognized approximately $2.7 million of excess tax benefits within the provision for income taxes. Additionally, the Company elected to prospectively apply the change in presentation of excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity. Accordingly, prior period classification of cash flows related to excess tax benefits were not adjusted.

8. NET INCOME (LOSS) PER SHARE

The following is a reconciliation of the weighted average number of common shares outstanding used in calculating basic and diluted net income (loss) per share (in thousands, except share and per share data):

9. SEGMENT REPORTING

ASC 280, Segment Reporting, establishes annual and interim reporting standards for an enterprise's business segments and related disclosures about its products, services, geographic areas and major customers. Under ASC 280, the method for determining what information to report is based upon the way management organizes the operating segments within the Company for making operating decisions and assessing financial performance. The Company manages its operations primarily on a geographic basis. The Chief Executive Officer, the Chief Financial Officer, and the Chief Technology Officer or the Company's Chief Operating Decision Makers (CODMs), evaluate performance of the Company and make decisions regarding allocation of resources based on geographic results. The Company's reportable segments are the Americas and Europe. The Americas segment is primarily North America. The Europe segment is primarily the United Kingdom. Each operating segment provides similar products and services.

The Company's CODMs evaluate the performance of its operating segments based on revenues and net income. The Company does not allocate research and development, sales and marketing, general and administrative, amortization expense, stock-based compensation expense, and commitment and contingencies for each segment as management does not consider this information in its evaluation of the performance of each operating segment. Revenues are attributed to each segment based on the ordering location of the customer or ship to location.

The following tables set forth the segment and geographic information for each period (in thousands):

		Revenue for the
		Three Months Ended				Six Months Ended
		September 30,				September 30,
		2017		2016		2017		2016

	$	72,483	$	63,183	$	141,581	$	123,224

Revenue is based upon the destination of shipments and the customers' service address. For the three and six months ended September 30, 2017 and 2016, intersegment revenues of approximately $4.4 million and $6.9 million, and $1.5 million and $2.6 million, respectively, were eliminated in consolidation, and have been excluded from the table above.

BUSINESS OVERVIEW

We are a leading provider of truly unified cloud communications. Our suite of products weaves together unified cloud communications, messaging, meeting and contact center solutions so today's organization can communicate at the speed of employee and customer expectations. Our technology provides one unified management platform with one communication experience for employees and customers, as well as a one real-time data analytics platform for constant learning and improvement.

Our fiscal year ends on March 31 of each calendar year. Each reference to a fiscal year in this report refers to the fiscal year ending March 31 of the calendar year indicated (for example, fiscal 2018 refers to the fiscal year ending March 31, 2018).

SUMMARY AND OUTLOOK

In the second quarter of fiscal year 2018, our service revenue from mid-market and enterprise customers grew 28% year-over year and represented 58% of total service revenue. New monthly recurring revenue (MRR) bookings from mid-market and enterprise customers and by our channel sales teams was 61% of total bookings for the quarter, reflecting strong demand for our services in our target market segments. Also, average monthly service revenue per mid-market and enterprise business customer (ARPU) increased 8% to a record $4,697, compared with $4,351 in the same period last year. The increase resulted from our success in selling a greater number of subscriptions to larger, more established customers.

In October 2017, we launched the new 8x8 Virtual Office Editions, in three product bundles: X2, X5 and X8. X8, our most unified offering, weaves together communications, collaboration with our contact center all into one solution. It includes an unlimited calling zone to 45 countries and a full suite of 8x8 Virtual Office features, such as HD voice, Virtual Office Meetings, HD Video, integrations with Salesforce, Zendesk and NetSuite CRM, Salesforce analytics for better and faster data insights, call recording, call quality reporting, and barge monitor whisper capabilities.

In order to position ourselves most effectively for our next phase of growth, we have identified the following strategic initiatives.

First, we are aligning global business units around our core market segments to optimize for growth. We bifurcated our internal sales operations into two separate sales operations - Small Business & eCommerce and Mid-market & Enterprise. These operations will align sales and delivery, connecting demand generation, services and support to drive revenue growth and profitability globally. Small Business & eCommerce will focus on our high-volume, transactional business, with the objective of accelerating growth and productivity through eCommerce and self-service. Midmarket & Enterprise will focus on creating and leveraging channel relationships to drive a consultative approach to our land and expand strategy for larger accounts in the US, Europe, Middle East and Asia, and Asia-Pacific regions.

Second, we have made several executive appointments in our marketing and sales organizations to align with our new sales operations and accelerate adoption of our solutions across all market segments.

Third, we have expanded our global field sales organization with both Mid-market and Enterprise Sales Executives and Channel Development Managers. Our field sales executives work directly with customer prospects to understand, customize, and optimize communications solution for customer's business while Channel Development Managers are responsible for recruiting and enabling partners in their respective territories, evangelizing the 8x8 brand and growing the sales pipeline with partners.

In the first fiscal quarter of 2018, we announced increased investments for sales and marketing expenses to accelerate the growth of our business in the mid-market and enterprise segments. We commenced these investments in the second quarter of fiscal 2018 and intend to incur them over several quarters. The precise timing of these additional expenditures, and the reporting periods in which they occur, will depend in part on when our management can implement the steps, particularly hiring additional personnel, necessary for achieving anticipated growth in our bookings and revenues. In addition, though we believe our new marketing and sales expenditures, and, to a lesser extent, our product development expenditures will help us achieve the bookings and revenue growth we are seeking, such growth in not assured, and will be impacted not only by the timing of those expenditures but also by our ability to effectively implement such plans and limit disruptions to our current operations while we do so. If we do not timely and effectively implement our new marketing, sales and product development plans, and productively

CRITICAL ACCOUNTING POLICIES & ESTIMATES

The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of assets and liabilities. On an on-going basis, we evaluate our critical accounting policies and estimates. We base our estimates on historical experience and on various other assumptions that we believe 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.

RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our condensed consolidated financial statements and the notes thereto.

		September 30,				Dollar	Percent
Service revenue		2017		2016		Change	Change
		(dollar amounts in thousands)
Three months ended	$	68,123	$	57,717	$	10,406	18.0%

Six months ended	$	133,214	$	113,013	$	20,201	17.9%
Percentage of total revenue		94.1%		91.7%

Service revenue consists primarily of our 8x8 cloud communication and collaboration services.

8x8 service revenues increased in the three and six months of fiscal year 2018 compared to the same period of the previous fiscal year primarily due to an increase in our business customer subscriber base (net of customer churn), and an increase in the average monthly service revenue per customer. Average monthly service revenue per customer increased from $409 at September 30, 2016 to $442 at September 30, 2017.

We expect growth in the number of business customers and average monthly service revenue per customer to continue in fiscal year 2018.

		September 30,				Dollar	Percent

Six months ended	$	8,367	$	10,211	$	(1,844)	-18.1%
Percentage of total revenue		5.9%		8.3%

Product revenue consists primarily of revenue from sales of IP telephones in conjunction with our 8x8 cloud communication service. Product revenue decreased for the three and six months ended September 30, 2017 primarily due to a decrease in equipment sales to business customers.

No customer represented greater than 10% of the Company's total revenues for the three and six months ended September 30, 2017 or 2016.

		September 30,				Dollar	Percent
Cost of service revenue		2017		2016		Change	Change
		(dollar amounts in thousands)
Three months ended	$	12,757	$	10,837	$	1,920	17.7%

Six months ended	$	24,419	$	21,072	$	3,347	15.9%
Percentage of service revenue		18.3%		18.6%

The cost of service revenue primarily consists of costs associated with network operations and related personnel, communication origination and termination services provided by third-party carriers, and technology licenses.

Cost of service revenue for the three months ended September 30, 2017 increased over the comparable period in the prior fiscal year primarily due to a $0.4 million increase in third-party network services expenses, a $0.4 million increase in amortization of intangibles expense, a $0.3 million increase in payroll and related costs, a $0.3 million increase in computer supply expenses, as well as other smaller cost increases.

17

Cost of service revenue for the six months ended September 30, 2017 increased over the comparable period in the prior fiscal year primarily due to a $0.6 million increase in third-party network services expenses, a $0.6 million increase in computer supply expenses, a $0.6 million increase in amortization of intangibles expense, a $0.4 million increase in payroll and related expenses, a $0.4 million increase in license and fee expenses, and a $0.3 million increase in depreciation expense.

We expect cost of service revenue to increase moderately as a percentage of service revenue during the remainder of fiscal year 2018.

		September 30,				Dollar	Percent
Cost of product revenue		2017		2016		Change	Change

Percentage of product revenue		116.9%		105.8%
Six months ended	$	9,982	$	11,287	$	(1,305)	-11.6%
Percentage of product revenue		119.3%		110.5%

The cost of product revenue consists primarily of IP Telephones, estimated warranty obligations and direct and indirect costs associated with product purchasing, scheduling, shipping and handling.

The cost of product revenue for the three and six months ended September 30, 2017 decreased over the comparable period in the prior fiscal year primarily due to a decrease in equipment shipped to customers. The increase in negative margin was due to additional discounting of equipment in the current period and an increase in rebates offered to customers for the purchase of IP telephones.

		September 30,				Dollar	Percent
Research and development		2017		2016		Change	Change
		(dollar amounts in thousands)
Three months ended	$	8,311	$	6,505	$	1,806	27.8%

Six months ended	$	16,254	$	13,215	$	3,039	23.0%
Percentage of total revenue		11.5%		10.7%

Research and development expenses consist primarily of personnel, system prototype design, and equipment costs necessary for us to conduct our development and engineering efforts.

The research and development expenses for the three months ended September 30, 2017 increased over the comparable period in the prior fiscal year primarily due to a $0.9 million increase in payroll and related costs, net of costs capitalized in accordance with ASC 350-40, a $0.5 million increase in stock-based compensation expense, and a $0.2 million increase in travel expenses.

The research and development expenses for the six months ended September 30, 2017 increased over the comparable period in the prior fiscal year primarily due to a $1.3 million increase in payroll and related costs, net of costs capitalized in accordance with ASC 350-40, a $0.8 million increase in stock-based compensation expenses, a $0.3 million increase in travel expenses, and a $0.2 million increase in recruiting expenses.

We expect research and development expenses to remain consistent as a percentage of total revenue during the remainder of fiscal year 2018 as we continue to invest in our product offerings.

Sales and marketing expenses consist primarily of personnel and related overhead costs for sales, marketing, and customer service which includes deployment engineering. Such costs also include outsourced customer service call center operations, sales commissions, as well as trade show, advertising and other marketing and promotional expenses.

Sales and marketing expenses for three months ended September 30, 2017 increased over the comparable period in the prior fiscal year primarily due to a $4.1 million increase in payroll and related costs, a $0.7 million increase in stock-based compensation costs, a $0.6 million increase in channel commission expenses, a $0.6 million increase in consulting, temporary personnel, and outside services, and a $0.4 million increase in travel expenses.

Sales and marketing expenses for the six months ended September 30, 2017 increased over the same period in the prior fiscal year primarily due to an $8.2 million increase in payroll and related costs, a $1.8 million increase in indirect channel commissions, a $1.7 million increase in facility allocation costs, a $1.5 million increase in stock-based compensation expenses, a $1.1 million increase in lead generation expenses, a $0.8 million increase in travel expenses, and a $0.7 million increase in consulting, temporary personnel, and outside services.

We expect sales and marketing expenses to increase as percentage of total revenue during the remainder of fiscal year 2018 as we continue to invest in the acquisition of mid-market and enterprise customers.

General and administrative expenses for three months ended September 30, 2017 increased over the comparable period in the prior fiscal year primarily due to a $0.9 million increase in payroll and related costs, a $0.8 million increase in stock-based compensation costs, a $0.5 million increase in temporary personnel, consulting and outside services, a $0.3 million increase in computer supply expenses, as well as other smaller cost increases.

General and administrative expenses for the six months ended September 30, 2017 increased over the same period in the prior fiscal year primarily because of a $1.9 million increase in payroll and related expenses, a $0.9 million increase in stock-based compensation expenses, a $0.9 million increase in consulting, temporary personnel, and outside services, a $0.4 million increase in computer supply expenses, as well as other smaller cost increases.

We expect general and administrative expenses to increase moderately as percentage of total revenue during the remainder of fiscal year 2018.

Other income, net, primarily consisted of interest income earned on our cash, cash equivalents and investments and amortization or accretion of investments in fiscal years 2018 and 2017. During the first quarter of fiscal year 2018, $1.4 million of the cash held in an escrow fund from our 2015 acquisition of DXI was returned to us and recorded as other income.

The change in our effective tax rate for the periods presented was due primarily to the change in pretax profitability, geographic mix of profits and losses, and adoption of ASU 2016-09 effective April 1, 2017 (see Note 1 and Note 7 in the notes to the consolidated financial statements for additional information on the effects of the adoption).

As described in Note 1 in the consolidated financial statements, we adopted the updated accounting standard for share-based payment accounting in the first quarter of fiscal year 2018. As a result, we recorded deferred tax assets of approximately $17.6 million with a corresponding increase to retained earnings. For the six months ended September 30, 2017, we recognized approximately $2.7 million of excess tax benefits within the provision for income taxes. Additionally, starting in the first quarter of fiscal year 2018, we presented the cash flows related to the stock-based compensation net excess tax benefits in operating activities rather than in financing activities in our statement of cash flows. Prior period classification of cash flows related to excess tax benefits were not adjusted.

We estimate our annual effective tax rate at the end of each quarter. In estimating the annual effective tax rate, we consider, among other things, annual pre-tax income, permanent tax differences, the geographic mix of pre-tax income and the application and interpretations of existing tax laws. We record the tax effect of certain discrete items, which are unusual or occur infrequently, in the interim period in which they occur, including changes in judgment about deferred tax valuation allowances. The determination of the effective tax rate reflects tax expense and benefit generated in certain domestic and foreign jurisdictions. However, jurisdictions with a year-to-date loss where no tax benefit can be recognized are excluded from the annual effective tax rate.

Liquidity and Capital Resources

As of September 30, 2017, we had $167.1 million in cash, cash equivalents and short-term investments.

Net cash provided by operating activities for the six months ended September 30, 2017 was approximately $11.2 million, compared with $13.4 million for the six months ended September 30, 2016. Cash provided by operating activities has historically been affected by the amount of net income (loss), changes in working capital accounts particularly in the timing and collection of payments, add-backs of non-cash expense items such as deferred taxes, depreciation and amortization, and with stock-based compensation.

The net cash used in investing activities for the six months ended September 30, 2017 was $6.3 million, during which we had proceeds from maturity and sale of short term investments of approximately $1.5 million, net of purchases of short term investments. We also had proceeds of $1.4 million from the settlement of an escrow claim in relation to our acquisition of DXI. We spent approximately $4.0 million on the purchase of property and equipment and capitalized $5.2 million of software costs in accordance with ASC 350-40. The net cash used in investing activities for the six months ended September 30, 2016 was $16.1 million, during which we purchased approximately $8.4 million of short term investments, net of sales and maturities of short term investments. We spent approximately $5.2 million on the purchase of property and equipment, and we capitalized $2.4 million of internal use software.

Net cash used in financing activities for the six months ended September 30, 2017 was approximately $11.8 million, which primarily resulted from $13.8 million of repurchases of our common stock related to shares withheld for payroll taxes and common stock repurchased under the 2017 Repurchase Plan, and $0.6 million in capital leases payments, offset by $2.8 million of cash received from the issuance of common stock under our employee stock plans. Net cash provided by financing activities for the six months ended September 30, 2016 was approximately $1.2 million, which primarily resulted from $2.6 million of cash received from the issuance of common stock under our employee stock purchase plan, reduced by $0.8 million of repurchases of our common stock related to shares withheld for payroll taxes, $0.3 million of payments on capital leases, and $0.2 million of payments of contingent consideration and escrow.

Contractual Obligations

There were no significant changes in our commitments under contractual obligations during the six months ended September 30, 2017, as disclosed in the Company's Annual Report on Form 10-K, for the year ended March 31, 2017.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Fluctuation Risk

The primary objective of our investment activities is to preserve principal while maximizing income without significantly increasing risk. Some of the securities in which we invest may be subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, we may maintain our portfolio of cash equivalents and investments in a variety of shorter term securities, including commercial paper, money market funds, debt securities and certificates of deposit. The risk associated with fluctuating interest rates is limited to our investment portfolio and we do not believe that a hypothetical change in interest rates of 100 basis points would have a significant impact on our interest income.

We do not have any outstanding debt instruments other than equipment under capital leases and, therefore, we were not exposed to market risk relating to interest rates.

Foreign Currency Exchange Risk

We have foreign currency risks related to our revenue and operating expenses denominated in currencies other than the U.S. dollar, primarily the British Pound, causing both our revenue and our operating results to be impacted by fluctuations in the exchange rates.

Gains or losses from the translation of certain cash balances, accounts receivable balances and intercompany balances that are denominated in these currencies impact our net income (loss). A hypothetical decrease in all foreign currencies against the US dollar of 10 percent, would not result in a material foreign currency loss on foreign-denominated balances. As our foreign operations expand, our results may be more impacted by fluctuations in the exchange rates of the currencies in which we do business.

At this time, we do not, but we may in the future, enter into financial instruments to hedge our foreign currency exchange risk.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Effectiveness of Disclosure Controls and Procedures

We maintain disclosure controls and procedures as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (Disclosure Controls) that are designed to ensure that information we are required to disclose in reports filed or submitted under the Securities and Exchange Act of 1934 is accumulated and communicated to management, including our principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure, and that such information is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

As of the end of the period covered by this Quarterly Report on Form 10-Q, under the supervision of our Chief Executive Officer and our Chief Financial Officer, we evaluated the effectiveness of our Disclosure Controls. Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our Disclosure Controls were effective as of September 30, 2017.

Limitations on the Effectiveness of Controls

Our management, including the Chief Executive Officer and Chief Financial Officer, do not expect that our Disclosure Controls or internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.

Changes in Internal Control over Financial Reporting

During the second quarter of fiscal year 2018, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
