8X8, Inc.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED
FINANCIAL STATEMENTS

8x8, Inc. (8x8 or the Company) is a leading provider of VoIP (Voice over Internet Protocol) technology and SaaS (Software as a Service) communication solutions in the cloud for SMBs (Small and Midsize Business) and mid-market and distributed enterprises. The Company delivers a broad suite of SaaS services to in-office and mobile devices spanning cloud telephony, virtual contact center and virtual meeting through its proprietary unified SaaS platform.

The Company was incorporated in California in February 1987 and was reincorporated in Delaware in December 1996.

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 2016 refers to the fiscal year ended March 31, 2016).

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, 2015. 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 and liabilities and 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, 2015 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, 2015 and notes thereto included in the Company's fiscal 2015 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.

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

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, 2015 filed with the SEC on May 29, 2015, and there have been no changes to the Company's significant accounting policies during the three months ended June 30, 2015, except as described in the "Recent Accounting Pronouncements" section below.

RECENT ACCOUNTING PRONOUNCEMENTS

In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This ASU changes the requirements for reporting discontinued operations in FASB ASU 205-20, such that a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. This ASU requires an entity to present, for each comparative period, the assets and liabilities of a disposal group that includes a discontinued operation separately in the asset and liability sections, respectively, of the statement of financial position, as well as additional disclosures about discontinued operations. Additionally, the ASU requires disclosures about a disposal of an individually significant component of an entity that does not qualify for discontinued operations presentation in the financial statements and expands the disclosures about an entity's significant continuing involvement with a discontinued operation. The accounting update is effective for annual periods beginning on or after December 15, 2014. We adopted this pronouncement for our fiscal year beginning April 1, 2015, and there was no effect on our consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) and the International Accounting Standards Board (IASB) has issued International Financial Reporting Standards (IFRS) 15, Revenue from Contracts with Customers. The issuance of these documents completes the joint effort by the FASB and the IASB to improve financial reporting by creating common revenue recognition guidance for U.S. GAAP and IFRS. The new guidance affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards. This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. In July 2015, the FASB voted to delay the effective date of this standard until the first quarter of 2018. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements.

4. INTANGIBLE ASSETS

The carrying value of intangible assets consisted of the following (in thousands):

At June 30, 2015, annual amortization of intangible assets, based upon our existing intangible assets and current useful lives, is estimated to be the following (in thousands):

In the first three months of fiscal 2016, the Company expensed all research and development costs in accordance with ASC 985-20, Costs of Software to be Sold, Leased or Marketed (ASC 985-20). At June 30, 2015 and March 31, 2015, total capitalized software development costs included in other long-term assets was approximately $0 and $1.0 million, respectively, and accumulated amortization costs related to capitalized software was approximately $0 and $0.5 million, respectively.

The Company accounts for computer software developed or obtained for internal use in accordance with ASC 350-40, Internal Use Software (ASC 350-40). In the first three months of fiscal 2016, the Company capitalized $0.5 million in accordance with ASC 350-40, which is classified as other assets. No such costs were capitalized in the first three months of fiscal 2015. As of June 30, 2015, the Company capitalized $2.0 million in accordance with ASC 350-40, of which $1.2 million is classified as other assets, and $0.8 million is classified as property and equipment. As of March 31, 2015, the Company capitalized $1.5 million in accordance with ASC 350-40, of which $0.8 million is classified as property and equipment and $0.7 million is classified as long-term assets. At June 30, 2015, the projects had not yet been placed into service, and accordingly no amortization has been recognized.

6. COMMITMENTS AND CONTINGENCIES

In the normal course of business, the Company may agree to indemnify other parties, including customers, lessors and parties to other transactions with the Company, with respect to certain matters such as breaches of representations or covenants or intellectual property infringement or other claims made by third parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, the Company has entered into indemnification agreements with its officers and directors.

It is not possible to determine the maximum potential amount of the Company's exposure under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material impact on the Company's operating results, financial position or cash flows. Under some of these agreements, however, the Company's potential indemnification liability might not have a contractual limit.

The Company accrues for the estimated costs that may be incurred under its product warranties upon revenue recognition. Changes in the Company's product warranty liability, which is included in cost of product revenues in the consolidated statements of income (loss), were as follows (in thousands):

In the third quarter of 2010, the Company amended its contract with one of its third party customer support vendors containing a minimum monthly commitment of approximately $0.4 million effective April 1, 2010. The agreement requires a 150-day notice to terminate. At June 30, 2015, the total remaining obligation under the contract was $2.2 million.

The Company entered into contracts with multiple vendors for third party network service which expire on various dates in fiscal 2016 through 2018. At June 30, 2015, future minimum annual payments under these third party network service contracts were as follows (in thousands):

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 February 22, 2011, the Company was named a defendant in, Bear Creek Technologies, Inc. v. 8x8, Inc. et al., filed in the U.S. District Court for the District of Delaware, along with 20 other defendants. On August 17, 2011, the suit was dismissed without prejudice as to the Company under Rule 21 of the Federal Rules of Civil Procedure. On August 17, 2011, Bear Creek Technologies, Inc. refiled its suit against the Company in the United States District Court for the District of Delaware. Further, on November 28, 2012, the U.S. Patent & Trademark Office initiated a Reexamination proceeding with a Reexamination Declaration explaining that there is a substantial new question of patentability, based on four separate grounds and affecting each claim of the patent which is the basis for the complaint filed against us.  On March 26, 2013, the USPTO issued a first Office Action in the Reexamination, with all claims of the '722 patent being rejected on each of the four separate grounds raised in the Request for Reexamination.  On July 10, 2013, the Company filed an informational pleading in support of and joining a motion to stay the proceeding in the District Court; the District Court granted the motion on July 17, 2013, based on the possibility that at least one of the USPTO rejections will be upheld and considering the USPTO's conclusion that Bear Creek's patent suffers from a defective claim for priority.  On March 24, 2014, the USPTO issued another Office Action in which the rejections of the claims were maintained.  On August 15, 2014, the USPTO issued a Right of Appeal Notice, as the USPTO maintained all rejections of the patent claims.  On September 15, 2014, Bear Creek Technologies, Inc. filed a Notice of Appeal of this decision with the Patent Trial and Appeal Board, and the USPTO's rejections are currently on appeal. By an order issued on May 5, 2015, the Court administratively closed this case with leave to reopen if further attention by the Court is required. 

On March 31, 2014, the Company was named as a defendant in a lawsuit, CallWave Communications LLC (CallWave) v. 8x8, Inc. CallWave also sued Fonality Inc. on March 31, 2014, and previously had sued other companies including Verizon, Google, T-Mobile, and AT&T. The Company answered the complaint and filed counterclaims in response thereto. On April 21, 2015, the Company filed its answer and alleged a number of counterclaims including patent misuse. On or about May 26, 2015, the parties agreed to settle all claims in the suit, including, (but not necessarily limited to) a release and/or covenant not to sue by the plaintiff on future claims that 8x8 products infringe the CallWave patents alleged to have been infringed. The case was dismissed with prejudice on June 5, 2015.

On December 31, 2014, the Company was named as a defendant in a lawsuit, Adaptive Data, LLC v. 8x8, Inc., filed in the U.S. District Court for the District of Delaware. Adaptive Data, LLC also sued another 36 other defendants on December 31, 2014 and another 16 defendants on January 5, 2015 regarding the same patents asserted in our case. Service of process was never effected on the Company.  The Court issued a Notice of Voluntary Dismissal on January 23, 2015.

On April 15, 2015, the Company was named as a defendant in a lawsuit, UrgenSync, LLC v. 8x8, Inc., filed in the U.S. District Court for the E.D. of Texas. UrgenSync, LLC also sued another 14 other defendants on the same day regarding the same patent asserted in the complaint filed against 8x8.  The Court issued an Order of Voluntary Dismissal with Prejudice on June 18, 2015.

On April 16, 2015, the Company was named as a defendant in a lawsuit, Slocumb Law Firm v. 8x8, Inc., filed in the United States District Court for the Middle District of Alabama. The Slocumb Law Firm alleges that it purchased certain business services from the Company that did not perform as advertised or expected, and asserts various causes of actions including fraud, breach of contract, violations of the Alabama Deceptive Trade Practices Act and negligence. On June 30, 2015, the Court granted the Company's motion to stay the case and compel the Slocumb Law Firm to arbitrate its claims against the Company in Santa Clara County, California pursuant to a clause mandating arbitration of disputes set forth in the terms and conditions to which Slocumb Law Firm agreed in connection with its purchase of business services from the Company. The Company has not yet received a formal arbitration demand from the Slocumb Law Firm, nor has discovery commenced. The Company intends to vigorously defend against the Slocumb Law Firm's claims.

State and Municipal Taxes

From time to time, the Company has received inquiries from a number of state and municipal taxing agencies with respect to the remittance of sales, use, telecommunications, excise, and income taxes. Several jurisdictions currently are conducting tax audits of the Company's records. The Company collects or has accrued for taxes that it believes are required to be remitted. The amounts that have been remitted have historically been within the accruals established by the Company.

As of June 30, 2015, there was $26.3 million of unamortized stock-based compensation expense related to unvested stock options and awards which is expected to be recognized over a weighted average period of 2.71 years.

The fair value of each of the Company's option grants has been estimated on the date of grant using the Black-Scholes pricing model with the following assumptions:

In February 2015, the Company's board of directors authorized the Company to purchase up to $20.0 million of its common stock from time to time until February 29, 2016 (the Repurchase Plan). Share repurchases, if any, will be funded with available cash. Repurchases under the Repurchase Plan may be made through open market purchases at prevailing market prices or in privately negotiated transactions. The timing, volume and nature of share repurchases are subject to market prices and conditions, applicable securities laws and other factors, and are at the discretion of the Company's management. Share repurchases under the Repurchase Plan may be commenced, suspended or discontinued at any time. The remaining authorized repurchase amount at June 30, 2015 was approximately $15.7 million. There were no stock repurchases made under the Repurchase Plan in the three months ended June 30, 2015.

The stock repurchase activity as of June 30, 2015 is summarized as follows:

For the three months ended June 30, 2015, the Company recorded a provision for income taxes of $0.8 million, which was primarily attributable to income from operations. For the three months ended June 30, 2014, the Company recorded a provision for income taxes of $0.7 million which was primarily attributable to income from operations.

The effective tax rate is calculated by dividing the income tax provision by net income before income tax expense.

At March 31, 2015, there were $2.4 million of unrecognized tax benefits that, if recognized, would have affected the effective tax rate.  The Company does not believe that there has been any significant change in the unrecognized tax benefits in the three-month period ended June 30, 2015, and does not expect the remaining unrecognized tax benefit to change materially in the next 12 months. To the extent that the remaining unrecognized tax benefits are ultimately recognized, they will have an impact on the effective tax rate in future periods.

15

The Company is subject to taxation in the U.S., California and various other states and foreign jurisdictions in which it has or had a subsidiary or branch operations or it is collecting sales tax. All tax returns from fiscal 1996 to fiscal 2015 may be subject to examination by the Internal Revenue Service, California and various other states. As of July 22, 2015, there were no active federal or state income tax audits. Returns filed in foreign jurisdictions may be subject to examination for the fiscal years 2011 to 2015.

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

The following shares attributable to outstanding stock options and restricted stock purchase rights were excluded from the calculation of diluted earnings per share because their inclusion would have been antidilutive (in thousands):

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.

As of June 30, 2015, the Company has reclassified the presentation of the information regarding its reportable segments to reflect a change from one reportable segment in prior periods to two reportable segments, due to changes in reporting structure as a result of a business acquisition that occurred in the first fiscal quarter of 2016. The Company manages its operations primarily on a geographic basis. The Company's chief operating decision makers (CODMs) are the Chief Executive Officer, the Chief Financial Officer, and the Chief Technology Officer, who evaluate performance of the Company and make decisions regarding allocation of resources based on geographic results.   The Company's reportable operating 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. Revenues are attributed to each segment based on the ordering location of the customer or ship to location. The Company allocates corporate overhead costs such as research and development, sales and marketing, general and administrative, amortization expense, stock-based compensation expense, and commitment and contingencies to the US segment. The Company did not allocate goodwill for each segment as the Company had not completed its analysis of assigning goodwill to its reporting units as of July 31, 2015.

The Company's revenue distribution by geographic region (based upon the destination of shipments and the customer's service address) was as follows:

Geographic area data is based upon the location of the property and equipment and is as follows (in thousands):

The following table provides financial information by operating segment for the three month period ending June 30, 2015 and 2014 (in thousands):

On May 26, 2015, the Company entered into a share purchase agreement with the shareholders of DXI Limited, API Telecom Limited, Easycallnow Limited and RAS Telecom Limited (collectively, DXI) for the purchase of the entire share capital of DXI. The transaction closed effective May 29, 2015 and was not subject to regulatory approvals. The total aggregate purchase price was approximately $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. Approximately 352,000 shares of common stock valued at approximately $3.0 million were issued only to former management shareholders of DXI as part of the share purchase agreement and are subject to certain restrictions, including a four-year annual vesting requirement based on the continued employment of such shareholders. Under ASC 805-10-55-25, Business Combinations, the shares are considered post acquisition compensation vs. consideration transferred. The value of the shares will be amortized over the vesting period of forty-eight months. The shares are further subject to indemnity claims asserted by the Company prior to vesting. Vesting of the shares is subject to acceleration in the event of the shareholder's death or disability, or upon an employment termination without adequate cause, as provided in the share purchase agreement. The cash escrow also applies only to the management shareholders of DXI and is to be released in annual installments over two years. The share purchase agreement contains representations and warranties by the management shareholders that are

17

customary in the UK for transactions of this size and nature. The Company also awarded restricted stock units representing the right to receive approximately 53,000 shares of common stock that were valued at approximately $482,000 to certain continuing employees of DXI, which will be amortized as stock-based compensation over the requisite service period.

The Company recorded the acquired tangible and identifiable intangible assets and liabilities assumed based on their estimated fair values. The excess of the consideration transferred over the aggregate fair values of the assets acquired and liabilities assumed is recorded as goodwill. The amount of goodwill recognized is primarily attributable to the expected contributions of the entity to the overall corporate strategy in addition to synergies and acquired workforce of the acquired business. The finite−lived intangible assets consist of the following: customer relationships, with an estimated weighted-average useful life of two and five years; and developed technology, with an estimated weighted-average useful life of seven years. The indefinite lived intangible asset consisted of a tradename. The fair value assigned to identifiable intangible assets acquired was based on estimates and assumptions made by management using various income approach methods. Intangible assets are amortized on a straight-line basis.

The preliminary fair values of the assets acquired and liabilities assumed are as follows (in thousands):

None of the goodwill recognized is expected to be deductible for income tax purposes.

DXI contributed revenue of approximately $1.1 million and net income was not material for the period from the date of acquisition to June 30, 2015. Total acquisition related costs were approximately $0.8 million. The Company determined it is impractical to include pro forma information given the difficulty in obtaining the historical financial information of DXI. Inclusion of such information would require the Company to make estimates and assumptions regarding DXI's historical financial results that we believe may ultimately prove inaccurate.

On June 18, 2015, the Company entered into an asset purchase agreement with the shareholder of Quality Software Corporation (QSC) and other parties affiliated with the shareholder and QSC for the purchase of certain assets as per the purchase agreement. The total aggregate fair value of the consideration was approximately $2.9 million, which was paid in cash to the QSC shareholder at closing. As part of the aggregate purchases price, there is also $0.5 million in contingent consideration payable subject to attainment of certain revenue and product release milestones for the acquired business, and $0.3 million in cash held by the Company in escrow to be retained for two years as security against indemnity claims made by the Company after the closing date. The preliminary fair value of the contingent consideration and escrow amounts was $0.7 million at the acquisition date.

The Company recorded the acquired identifiable intangible assets and liabilities assumed based on their estimated fair values. The excess of the consideration transferred over the aggregate fair values of the assets acquired and liabilities assumed is recorded as goodwill. The amount of goodwill recognized is primarily attributable to the expected contributions of the entity to the overall corporate strategy in addition to synergies and acquired workforce of the acquired business. The finite−lived intangible assets consist of the following: customer relationships, with an estimated weighted-average useful life of five years; and developed technology, with an estimated weighted-average useful life of seven years. The indefinite lived intangible asset consisted of a tradename. The fair value assigned to identifiable intangible assets acquired was based on estimates and assumptions made by management using various income approach methods. Intangible assets are amortized on a straight-line basis.

18

The preliminary fair values of the assets acquired and liabilities assumed are as follows (in thousands):

The goodwill recognized is expected to be deductible for income tax purposes.

QSC's contributions to revenue and income for the period from the date of acquisition to June 30, 2015 was not material. Total acquisition related costs were approximately $0.1 million.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Management Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. For example, words such as "may," "will," "should," "estimates," "predicts," "potential," "continue," "strategy," "believes," "anticipates," "plans," "expects," "intends," and similar expressions are intended to identify forward-looking statements. You should not place undue reliance on these forward-looking statements. Actual results and trends may differ materially from historical results or those projected in any such forward-looking statements depending on a variety of factors. These factors include, but are not limited to, customer acceptance and demand for our cloud communications and collaboration services, the quality and reliability of our services, the prices for our services, customer renewal rates, customer acquisition costs, our ability to compete effectively in the hosted telecommunications and cloud-based computing services business, actions by our competitors, including price reductions for their competitive services, our ability to provide cost-effective and timely service and support to larger distributed enterprises, potential federal and state regulatory actions, compliance costs, potential warranty claims and product defects, our need for and the availability of adequate working capital, our ability to innovate technologically, the timely supply of products by our contract manufacturers, our management's ability to execute its plans, strategies and objectives for future operations, including the execution of integration plans, and to realize the expected benefits of our acquisitions, and potential future intellectual property infringement claims and other litigation that could adversely affect our business and operating results. All forward-looking statements included in this report are based on information available to us on the date hereof, and we assume no obligation to update any such forward-looking statements. In addition to the factors discussed elsewhere in this Form 10-Q, see the Risk Factors discussion in Item 1A of our 2015 Form 10-K. The forward-looking statements included in this Form 10-Q are made only as of the date of this report, and we undertake no obligation to update the forward-looking statements to reflect subsequent events or circumstances.

We are a leading provider of VoIP and SaaS communication solutions in the cloud for SMBs and mid-market and distributed enterprises. We deliver a broad suite of SaaS services including hosted cloud telephony, virtual contact center, and virtual meeting to in-office and mobile devices through our proprietary unified SaaS platform. Our integrated, "pure-cloud" services platform is based on internally owned and managed technologies and is uniquely positioned to serve mid-market and enterprise businesses making the shift to cloud based Unified Communications. We make a full set of unified communications capabilities including cloud telephony, contact center, video and web conferencing available from anywhere in the world. With 8x8 analytics and reporting, our customers have a robust suite of web based tools that provide enterprise-level analytics that can be used to make highly informed business decisions, whether employees are mobile via the mobile client or in-office using a softphone, or a desk phone. Since fiscal 2004, substantially all of our revenue has been generated from the sale, license and provision of communications services. Prior to fiscal 2003, our focus was on our Voice over Internet Protocol semiconductor business.

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 2016 refers to the fiscal year ending March 31, 2016).

In the first quarter of fiscal 2016, our new monthly recurring revenue sold to mid-market customers and by channel sales teams increased 38% year-over-year reflecting strong demand for our services in our target market segment. Revenue from midmarket customers increased 40% year-over year and now represents 45% of our total service revenue. Average monthly service revenue per business customer increased 20% to a record $353, compared with $293 in the same period last year. Of the $353, DXI contributed $27 to our average monthly service revenue per customer. DXI revenues are primarily usage based. As such, revenues and average monthly service revenue per customer can fluctuate from quarter to quarter. The Company added more than 1,000 net new customers in our first fiscal quarter excluding customers from DXI.

In addition, we closed the acquisitions of DXI and QSC, which broaden our geographic footprint in the UK and Europe, expand our cloud communications portfolio, and add technical development talent in both London, England and Cluj, Romania. We also enhanced our contact center capabilities with focused R&D to deliver one of the most complete platform of cloud-based communications services available to midmarket and enterprise customers. Our ability to offer a broad range of cloud-based mission critical communications services is bringing us larger deals where we continue to displace incumbent, premises-based systems.

As we continue our focus on building a more profitable and sustaining midmarket customer base, one that contributes significantly greater lifetime value than the average small business customer, we are adding fewer one - five line business customers. We expect this trend to continue based on our continued focus on selling to larger businesses. As our average business customer size continues to grow, 8x8 management believes the net additional customer metric no longer correlates to our monthly recurring and top line revenue growth.

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.

See Item 1 of Part I, "Financial Statements - Note 1 - Basis of Presentation - Recent Accounting Pronouncements."

We periodically review certain key business metrics, within the context of our articulated performance goals, in order to evaluate the effectiveness of our operational strategies, allocate resources and maximize the financial performance of our business. The selected operating statistics include the following:

RESULTS OF OPERATIONS

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

Service revenue consists primarily of revenue attributable to the provision of our 8x8 cloud communication and collaboration services, and royalties earned from cloud technology licenses. We expect that 8x8 service revenues will continue to comprise nearly all of our service revenues for the foreseeable future. 8x8 service revenues increased in the first quarter of fiscal 2016 primarily due to a one-time $1.2 million accelerated technology license payment, an increase in our business customer subscriber base (net of customer churn) which includes customers acquired as part of the DXI and QSC acquisitions in the latter part of the quarter, and an increase in the average monthly service revenue per customer. Average monthly service revenue per customer increased from $293 at June 30, 2014 to $353 for at June 30, 2015. We expect growth in the number of business customers and average monthly service revenue per customer to continue to grow in fiscal 2016.

Product revenue consists primarily of revenue from sales of IP telephones in conjunction with our 8x8 cloud telephony service. Product revenue increased for the three months ended June 30, 2015 primarily due to an increase in equipment sales to business customers.

No customer represented greater than 10% of the Company's total revenues for the three months ended June 30, 2015 or 2014.
