Notes to Financial Statements
Company	*THE COMPANY* 8x8, Inc. ("8x8" or the "Company") was incorporated in California in February 1987 and was reincorporated in Delaware in December 1996. The Company is a leading provider of enterprise cloud communications solutions, including unified communications, team collaboration, contact center, and analytics, integrated over a single Software-as-a-Service (SaaS) platform. The 8x8 Communications Cloud^TM offers businesses a secure, reliable and simplified approach to transitioning their legacy, on-premises communications systems to the cloud. This comprehensive solution, built from owned and managed cloud technologies, enables customers to rely on a single provider for their global communications and contact center capabilities as well as customer support requirements. 8x8 customers are spread across more than 100 countries and range from small businesses to large enterprises. Since fiscal 2004, substantially all revenue has been generated from the sale of communications services and related hardware. Prior to fiscal 2003, the Company's main business was Voice over Internet Protocol semiconductors.
Fiscal Period	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).
Principles of Consolidation	*PRINCIPLES OF CONSOLIDATION* The consolidated financial statements include the accounts of 8x8 and its subsidiaries. All material intercompany accounts and transactions have been eliminated.
Reclassification	*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 consolidated balance sheet as of March 31, 2018. Assets in the amount of $7.7 million, net of accumulated amortization, have been reclassified in the consolidated 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 consolidated balance sheets and 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.
Use of Estimates	*USE OF ESTIMATES* The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to bad debts, returns reserve for expected cancellations, income and sales tax, and litigation and other contingencies. The Company bases its estimates on historical experience and on various other assumptions. Actual results could differ from those estimates under different assumptions or conditions.
Service Revenue	Service Revenue The Company recognizes service revenue, mainly from subscription services to its cloud-based voice, call center, video and collaboration solutions, when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, price is fixed or determinable and collectability is reasonably assured. The Company defers recognition of service revenues in instances when cash receipts are received before services are delivered and recognizes deferred revenues ratably, over the course of the contract, as services are provided. Under the terms of the Company's typical subscription agreements, new customers can terminate their service within 30 days of order placement and receive a full refund of fees previously paid. The Company has determined that it has sufficient history of subscriber conduct to make a reasonable estimate of cancellations within the 30-day trial period. Therefore, the Company recognizes new subscriber revenue that is fixed or determinable and that is not contingent on future performance or future deliverables in the month in which the new order was shipped, net of an allowance for expected cancellations. The Company recognizes revenue from product sales, mainly IP telephones, for which there are no related services to be rendered upon shipment to customers provided that persuasive evidence of an arrangement exists, the price is fixed or determinable, title has transferred, collection of resulting receivables is reasonably assured, there are no customer acceptance requirements, and there are no remaining significant obligations. Gross outbound shipping and handling charges are recorded as revenue, and the related costs are included in cost of goods sold. Reserves for returns and allowances for customer sales are recorded at the time of shipment. In accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 605, Revenue Recognition, the Company records shipments to distributors, retailers, channel partners, and resellers, where the right of return exists, as deferred revenue. The Company defers recognition of revenue on product sales to resellers until the products have been sold to the end-customer. The Company records revenue net of any sales and service related taxes and mandatory government charges that are billed to its customers. The Company believes this approach results in consolidated financial statements that are more easily understood by users.

The Company believes this approach results in consolidated financial statements that are more easily understood by users.
Revenue Recognition for Multiple Element Arrangements	Multiple Element Arrangements ASC 605-25, Revenue Recognition - Multiple Element Arrangements, requires that revenue arrangements with multiple deliverables be divided into separate units of accounting if the deliverables in the arrangement meet specific criteria. The provisioning of the cloud service with the accompanying IP telephone constitutes a revenue arrangement with multiple deliverables. For arrangements with multiple deliverables, the Company allocates the arrangement consideration to all units of accounting based on their relative selling prices. In such circumstances, the accounting principles establish a hierarchy to determine the relative selling price to be used for allocating arrangement consideration to units of accounting as follows: (i) vendor-specific objective evidence of fair value ("VSOE"), (ii) third-party evidence of selling price ("TPE"), and (iii) best estimate of the selling price ("BESP"). VSOE generally exists only when a Company sells the deliverable separately, on more than a limited basis, at prices within a relatively narrow range. When VSOE cannot be established, the Company attempts to establish the selling price of deliverables based on relevant TPE. TPE is determined based on manufacturer's prices for similar deliverables when sold separately, when possible. As the Company has historically been unable to establish a selling price using VSOE or TPE, it uses a BESP for the allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the product or service was sold on a stand-alone basis. BESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings. The Company determines BESP for a product or service by considering multiple factors including, but not limited to: the price list established by its management which is typically based on general pricing practices and targeted gross margin of products and services sold; and analysis of pricing history of new arrangements, including multiple element and stand-alone transactions. In accordance with the guidance of ASC 605-25, when the Company enters into revenue arrangements with multiple deliverables the Company allocates arrangement consideration, among the products and subscriber services based on their relative selling prices. Arrangement consideration allocated to the sold products that is fixed or determinable and that is not contingent on future performance or future deliverables is recognized as product revenues during the period of the sale less the allowance for estimated returns during the 30-day trial period. Arrangement consideration allocated to subscriber services that is fixed or determinable and that is not contingent on future performance or future deliverables is recognized ratably as service revenues as the related services are provided, which is generally over the initial contract term.
Cash, Cash Equivalents and Investments	*CASH, CASH EQUIVALENTS AND INVESTMENTS* The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. At March 31, 2018 and 2017, all investments were classified as available-for-sale and reported at fair value, based either upon quoted prices in active markets, quoted prices in less active markets, or quoted market prices for similar investments, with unrealized gains and losses, net of related tax, if any, included in other comprehensive income (loss) and disclosed as a separate component of stockholders' equity. Realized gains and losses on sales of all such investments are reported within the caption of other income in the consolidated statements of operations and computed using the specific identification method. The Company classifies its investments as current based on the nature of the investments and their availability for use in current operations. The Company's investments in marketable securities are monitored on a periodic basis for impairment. In the event that the carrying value of an investment exceeds its fair value and the decline in value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis for the investment is established. These available-for-sale investments are primarily held in the custody of one major financial institution.
Accounts Receivable Allowance	*ACCOUNTS RECEIVABLE ALLOWANCE* The Company estimates the amount of uncollectible accounts receivable at the end of each reporting period based on the aging of the receivable balance, current and historical customer trends, and communications with its customers. Amounts are written off only after considerable collection efforts have been made and the amounts are determined to be uncollectible.
Property and Equipment	*PROPERTY AND EQUIPMENT* Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method. Estimated useful lives of three years are used for equipment, software and software development costs and five years for furniture and fixtures. Amortization of leasehold improvements is computed using the shorter of the remaining facility lease term or the estimated useful life of the improvements. Maintenance, repairs and ordinary replacements are charged to expense. Expenditures for improvements that extend the physical or economic life of the property are capitalized. Gains or losses on the disposition of property and equipment are recorded in the Consolidated Statements of Operations. Construction in progress primarily relates to costs to acquire or internally develop software for internal use not fully completed as of March 31, 2018.
Accounting for Long-Lived Assets	*ACCOUNTING FOR LONG-LIVED ASSETS* The Company reviews the recoverability of its long-lived assets, such as property and equipment, definite lived intangibles or capitalized software, when events or changes in circumstances occur that indicate that the carrying value of the asset or asset group may not be recoverable. Examples of such events could include a significant disposal of a portion of such assets, an adverse change in the market involving the business employing the related asset or a significant change in the operation or use of an asset. The assessment of possible impairment is based on the Company's ability to recover the carrying value of the asset or asset group from the expected future cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset or asset group, an impairment loss is recognized for the difference between estimated fair value and carrying value. The measurement of impairment requires management to estimate the fair value of long-lived assets and asset groups through future cash flows. See Note 4 for further discussion on impairment charges incurred.
Goodwill and Other Intangible Assets	*GOODWILL AND OTHER INTANGIBLE ASSETS* Goodwill represents the excess fair value of consideration transferred over the fair value of net assets acquired in business combinations. Goodwill and intangible assets with indefinite useful lives are not amortized but are tested annually for impairment and more often if there is an indicator of impairment. The Company has determined that it has three reporting units and allocates goodwill to the reporting units for the purposes of its annual impairment test. The Company's annual goodwill impairment test is performed on January 1 each year. No goodwill impairment charges were recorded in the periods presented. Intangible assets with finite useful lives are amortized on a straight-line basis over the periods benefited. Amortization expense for the customer relationship intangible asset is included in sales and marketing expenses. Amortization expense for technology is included in cost of service revenue.
Warranty Expense	*WARRANTY EXPENSE* The Company accrues for estimated product warranty cost upon revenue recognition. Accruals for product warranties are calculated based on the Company's historical warranty experience adjusted for any specific requirements.
Research, Development and Software Costs	*RESEARCH & DEVELOPMENT AND SOFTWARE COSTS* Software developed or obtained for internal use in accordance with ASC 350-40, Internal-Use Software (ASC 350-40), is capitalized during the application development stage. In accordance with authoritative guidance, the Company begins to capitalize costs to develop software when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed, and the software will be used as intended. Once the project has been completed, these costs are amortized on a straight - line basis over the estimated useful life of the related asset, generally estimated to be three years. Costs incurred prior to meeting these criteria together with costs incurred for training and maintenance are expensed as incurred and recorded in research and development expense on our consolidated statements of operations. The Company classifies software development costs associated with the development of the Company's products and services as property and equipment. See Note 3 for further details.
Advertising Costs	*ADVERTISING COSTS* Advertising costs are expensed as incurred and were $14.5 million, $9.5 million and $8.5 million for the years ended March 31, 2018, 2017 and 2016, respectively.
Foreign Currency Translation	*FOREIGN CURRENCY TRANSLATION* The Company has determined that the functional currency of each of its foreign subsidiaries are the subsidiary's local currency. The Company believes this most appropriately reflects the current economic facts and circumstances of the Company's subsidiaries' operations. The assets and liabilities of the subsidiaries are translated at the applicable exchange rate as of the end of the balance sheet period and revenue and expenses are translated at an average rate over the period presented. Resulting currency translation adjustments are recorded as a component of accumulated other comprehensive income or loss within the stockholder's equity.
Business Segments	*BUSINESS SEGMENTS* The Company has two reportable segments, 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 chief operating decision makers, the Chief Executive Officer, Chief Financial Officer, and Chief Technology Officer, evaluate performance of the Company and makes decisions regarding allocation of resources based on geographical results. 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.
Concentrations	*CONCENTRATIONS* Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents, investments and trade accounts receivable. The Company has cash equivalents and investment policies that limit the amount of credit exposure to any one financial institution and restrict placement of these funds to financial institutions evaluated as highly credit-worthy. The Company has not experienced any material losses relating to its investments. The Company sells its products to business customers and distributors. The Company performs ongoing credit evaluations of its customers' financial condition and generally does not require collateral from its customers. At March 31, 2018 and 2017, no customer accounted for more than 10% of accounts receivable. The Company purchases all of its hardware products from suppliers that manufacturer the hardware directly. The inability of any supplier to fulfill supply requirements of the Company could materially impact future operating results, financial position or cash flows. The Company also relies primarily on third-party network service providers to provide telephone numbers and PSTN call termination and origination services for its customers. If these service providers failed to perform their obligations to the Company, such failure could materially impact future operating results, financial position and cash flows.
Fair Values of Financial Instruments	*FAIR VALUE OF FINANCIAL INSTRUMENTS* The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal market or the most advantageous market in which it would transact. The accounting guidance for fair value measurement requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs are inputs that reflect the assumptions market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the factors that market participants would use in valuing the asset or liability developed based on the best information available in the circumstances. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value by requiring that the most observable inputs be used when available. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows: Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets). Level 3 applies to assets or liabilities for which fair value is derived from valuation techniques in which one or more significant inputs are unobservable, including the Company's own assumptions. The estimated fair value of financial instruments is determined by the Company using available market information and valuation methodologies considered to be appropriate. The carrying amounts of the Company's cash and cash equivalents, accounts receivable and accounts payable approximate their fair values due to their short maturities. The Company's investments are carried at fair value.
Accounting for Stock-Based Compensation	*ACCOUNTING FOR STOCK-BASED COMPENSATION* The Company accounts for its employee stock options and other stock awards under the provisions of ASC 718 - Stock Compensation. Stock-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized as an expense over the employee's requisite service period (generally the vesting period of the equity grant), net of estimated forfeitures. To value option grants the Company uses the Black-Scholes option valuation model. Fair value determined using the Black-Scholes option valuation model varies based on assumptions used for the expected stock prices volatility, expected life, risk-free interest rates and future dividend payments. The Company used the historical volatility of its stock over a period equal to the expected life of the options. The expected life assumptions represent the weighted-average period stock-based awards are expecting to remain outstanding. These expected life assumptions were established through the review of historical exercise behavior of stock-based award grants with similar vesting periods. The risk-free interest rates were based on the closing market bid yields of actively traded U.S. treasury securities in the over-the-counter market for the expected term equal to the expected term of the option. The dividend yield assumption is based on the Company's history of not paying dividends. The Company issued performance stock units (PSUs) to a group of executives with vesting that is contingent on both market performance and continued service during the fiscal year ended March 31, 2018: 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 the Company's common stock performance is below negative 30% relative to the benchmark, no shares will be issued. The Company issued PSUs to a group of executives with vesting that is contingent on both market performance and continued service during the fiscal year ended March 31, 2017: These PSUs vest (1) 50% on September 22, 2018 and (2) 50% on September 27, 2019, 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 by 2% of the target numbers. In the event the Company's common stock performance is below negative 30%, relative to the benchmark, no shares will be issued. 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.
Comprehensive Income (Loss)	*COMPREHENSIVE (LOSS) INCOME* Comprehensive income (loss), as defined, includes all changes in equity (net assets) during a period. The difference between net income (loss) and comprehensive income (loss) is due to foreign currency translation adjustments and unrealized gains or losses on investments classified as available-for-sale.
Net Income (Loss) Per Share	*NET INCOME (LOSS) PER SHARE* Basic net income (loss) per share is computed by dividing net income (loss) available to common stockholders (numerator) by the weighted average number of vested, unrestricted common shares outstanding during the period (denominator). Diluted net income (loss) per share is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method unless their effect is anti-dilutive. Dilutive potential common shares include outstanding stock options and employee restricted purchase rights.
Deferred Rent	*DEFERRED RENT* The Company recognizes rent expense on a straight-line basis for all operating lease arrangements with the difference between required lease payments and rent expense recorded as deferred rent. The difference results from rent holidays, rent escalations and tenant improvement allowances, which are amortized over the lease term.
Recently Adopted Accounting Pronouncements	*RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS* In November 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-17, Income Taxes - Balance Sheet Classification of Deferred Taxes (Topic 740). This ASU requires all deferred tax liabilities and assets to be presented in the balance sheet as noncurrent. As permitted, the Company early adopted this standard prospectively during the quarter ended June 30, 2016. The adoption of this standard resulted in reclassifying current deferred income tax assets to noncurrent deferred income tax assets and current deferred income tax liabilities to noncurrent deferred income tax liabilities. No prior periods were retrospectively adjusted. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which is intended to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. As a result of the adoption in fiscal year 2018, stock-based compensation excess tax benefits or tax deficiencies will be reflected in the consolidated statement of operations within the provision for income taxes. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230), which provides guidance on how restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The Company elected to early adopt this ASU for fiscal year 2018 and disclosed restricted cash in the amount of $8.1 million in the consolidated balance sheets as of March 31, 2018. No prior periods were retrospectively adjusted. In January 2017, the FASB issued ASU No. 2017-04, Intangibles and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates the requirement to calculate the implied fair value of goodwill but rather require an entity to record an impairment charge based on the excess of a reporting unit's carrying value over its fair value. This amendment is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company elected to early adopt this ASU for fiscal year 2018. No prior periods were retrospectively adjusted.
Recent Accounting Pronouncements	*RECENT ACCOUNTING PRONOUNCEMENTS* In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Accounting Standards Codification 606 or ASC 606), which replaces numerous requirements in U.S. GAAP and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. ASC 606 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 in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. It defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates are required within the revenue recognition process than are required under current GAAP (ASC 605). The new standard permits the use of either the full retrospective or modified retrospective transition method. The Company adopted the new standard effective April 1, 2018 using the modified retrospective method. Under the retrospective method prior period financial information is not revised, but instead a cumulative impact is recorded on the day of adoption with a corresponding offset recorded to stockholder's equity. Under the new standard, the Company expects in some cases to recognize revenue earlier than under ASC 605 guidance when the customer receives services or equipment for a reduced consideration at the onset of an arrangement, for example the initial month's services or equipment are discounted, as a result of the elimination of contingent revenue guidance. Under ASC 605 guidance, amounts allocated to delivered items are limited to amounts that are not contingent on the provision of future services. The impact of adopting the new standard on the Company's total revenues and deferred revenue is not expected to be material. With the adoption of ASC 606 the Company also adopted ASC 340-40, Other Assets and Deferred Costs - Contracts with Customers, which requires the deferral of incremental costs of obtaining a customer contract which, under the old guidance, were expensed as incurred. Under the new standard, the Company will defer all incremental sales commission costs and amortize them over the expected period of benefit, which is estimated to be five years. The amortization cost will be charged to sales and marketing costs on the consolidated statements of operations. The Company expects the cumulative impact of these deferred costs to be approximately $35 million to $40 million with a corresponding decrease to accumulated deficit as of April 1, 2018. There will not be any significant tax impact to the Company's consolidated statements of operations and consolidated balance sheet relating to the adoption of the new standard due to the valuation allowance recorded against to the Company's deferred tax assets. The Company has established new accounting policies, is implementing processes, and implementing internal controls necessary to support the requirements of the new standard. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires companies to generally recognize on the balance sheet operating and financing lease liabilities and corresponding right-of-use assets. The update also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. The update requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. This amendment is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which provides guidance for measurement and recognition of expected credit losses for financial assets held based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The amendment is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for fiscal years beginning after December 15, 2018. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which provides guidance on how certain cash receipts and cash payments are to be presented and classified in the statement of cash flows. This amendment is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its Consolidated Statements of Cash Flows. In October 2016, the FASB has issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which provides guidance on how an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This amendment is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements. In January 2017, the FASB has issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This amendment is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements.
Indemnifications	Indemnifications 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.

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 consolidated balance sheet as of March 31, 2018. Assets in the amount of $7.7 million, net of accumulated amortization, have been reclassified in the consolidated 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 consolidated balance sheets and 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.

Use of Estimates

USE OF ESTIMATES

The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to bad debts, returns reserve for expected cancellations, income and sales tax, and litigation and other contingencies. The Company bases its estimates on historical experience and on various other assumptions. Actual results could differ from those estimates under different assumptions or conditions.

Service Revenue

Service Revenue

The Company recognizes service revenue, mainly from subscription services to its cloud-based voice, call center, video and collaboration solutions, when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, price is fixed or determinable and collectability is reasonably assured. The Company defers recognition of service revenues in instances when cash receipts are received before services are delivered and recognizes deferred revenues ratably, over the course of the contract, as services are provided.

Under the terms of the Company's typical subscription agreements, new customers can terminate their service within 30 days of order placement and receive a full refund of fees previously paid. The Company has determined that it has sufficient history of subscriber conduct to make a reasonable estimate of cancellations within the 30-day trial period. Therefore, the Company recognizes new subscriber revenue that is fixed or determinable and that is not contingent on future performance or future deliverables in the month in which the new order was shipped, net of an allowance for expected cancellations. The Company recognizes revenue from product sales, mainly IP telephones, for which there are no related services to be rendered upon shipment to customers provided that persuasive evidence of an arrangement exists, the price is fixed or determinable, title has transferred, collection of resulting receivables is reasonably assured, there are no customer acceptance requirements, and there are no remaining significant obligations. Gross outbound shipping and handling charges are recorded as revenue, and the related costs are included in cost of goods sold. Reserves for returns and allowances for customer sales are recorded at the time of shipment. In accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 605, Revenue Recognition, the Company records shipments to distributors, retailers, channel partners, and resellers, where the right of return exists, as deferred revenue. The Company defers recognition of revenue on product sales to resellers until the products have been sold to the end-customer.

The Company records revenue net of any sales and service related taxes and mandatory government charges that are billed to its customers. The Company believes this approach results in consolidated financial statements that are more easily understood by users.

Product Revenue

Revenue Recognition for Multiple Element Arrangements

Multiple Element Arrangements

ASC 605-25, Revenue Recognition - Multiple Element Arrangements, requires that revenue arrangements with multiple deliverables be divided into separate units of accounting if the deliverables in the arrangement meet specific criteria. The provisioning of the cloud service with the accompanying IP telephone constitutes a revenue arrangement with multiple deliverables. For arrangements with multiple deliverables, the Company allocates the arrangement consideration to all units of accounting based on their relative selling prices. In such circumstances, the accounting principles establish a hierarchy to determine the relative selling price to be used for allocating arrangement consideration to units of accounting as follows: (i) vendor-specific objective evidence of fair value ("VSOE"), (ii) third-party evidence of selling price ("TPE"), and (iii) best estimate of the selling price ("BESP").

VSOE generally exists only when a Company sells the deliverable separately, on more than a limited basis, at prices within a relatively narrow range. When VSOE cannot be established, the Company attempts to establish the selling price of deliverables based on relevant TPE. TPE is determined based on manufacturer's prices for similar deliverables when sold separately, when possible. As the Company has historically been unable to establish a selling price using VSOE or TPE, it uses a BESP for the allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale if the product or service was sold on a stand-alone basis. BESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings. The Company determines BESP for a product or service by considering multiple factors including, but not limited to:

the price list established by its management which is typically based on general pricing practices and targeted gross margin of products and services sold; and
analysis of pricing history of new arrangements, including multiple element and stand-alone transactions.

In accordance with the guidance of ASC 605-25, when the Company enters into revenue arrangements with multiple deliverables the Company allocates arrangement consideration, among the products and subscriber services based on their relative selling prices. Arrangement consideration allocated to the sold products that is fixed or determinable and that is not contingent on future performance or future deliverables is recognized as product revenues during the period of the sale less the allowance for estimated returns during the 30-day trial period. Arrangement consideration allocated to subscriber services that is fixed or determinable and that is not contingent on future performance or future deliverables is recognized ratably as service revenues as the related services are provided, which is generally over the initial contract term.

Cash, Cash Equivalents and Investments

CASH, CASH EQUIVALENTS AND INVESTMENTS

The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.

At March 31, 2018 and 2017, all investments were classified as available-for-sale and reported at fair value, based either upon quoted prices in active markets, quoted prices in less active markets, or quoted market prices for similar investments, with unrealized gains and losses, net of related tax, if any, included in other comprehensive income (loss) and disclosed as a separate component of stockholders' equity. Realized gains and losses on sales of all such investments are reported within the caption of other income in the consolidated statements of operations and computed using the specific identification method. The Company classifies its investments as current based on the nature of the investments and their availability for use in current operations. The Company's investments in marketable securities are monitored on a periodic basis for impairment. In the event that the carrying value of an investment exceeds its fair value and the decline in value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis for the investment is established. These available-for-sale investments are primarily held in the custody of one major financial institution.

Accounts Receivable Allowance

ACCOUNTS RECEIVABLE ALLOWANCE

The Company estimates the amount of uncollectible accounts receivable at the end of each reporting period based on the aging of the receivable balance, current and historical customer trends, and communications with its customers. Amounts are written off only after considerable collection efforts have been made and the amounts are determined to be uncollectible.

Property and Equipment

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method. Estimated useful lives of three years are used for equipment, software and software development costs and five years for furniture and fixtures. Amortization of leasehold improvements is computed using the shorter of the remaining facility lease term or the estimated useful life of the improvements.

Maintenance, repairs and ordinary replacements are charged to expense. Expenditures for improvements that extend the physical or economic life of the property are capitalized. Gains or losses on the disposition of property and equipment are recorded in the Consolidated Statements of Operations.

Construction in progress primarily relates to costs to acquire or internally develop software for internal use not fully completed as of March 31, 2018.

Accounting for Long-Lived Assets

ACCOUNTING FOR LONG-LIVED ASSETS

The Company reviews the recoverability of its long-lived assets, such as property and equipment, definite lived intangibles or capitalized software, when events or changes in circumstances occur that indicate that the carrying value of the asset or asset group may not be recoverable. Examples of such events could include a significant disposal of a portion of such assets, an adverse change in the market involving the business employing the related asset or a significant change in the operation or use of an asset. The assessment of possible impairment is based on the Company's ability to recover the carrying value of the asset or asset group from the expected future cash flows (undiscounted and without interest charges) of the related operations. If these cash flows are less than the carrying value of such asset or asset group, an impairment loss is recognized for the difference between estimated fair value and carrying value. The measurement of impairment requires management to estimate the fair value of long-lived assets and asset groups through future cash flows. See Note 4 for further discussion on impairment charges incurred.

Goodwill and Other Intangible Assets

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill represents the excess fair value of consideration transferred over the fair value of net assets acquired in business combinations. Goodwill and intangible assets with indefinite useful lives are not amortized but are tested annually for impairment and more often if there is an indicator of impairment. The Company has determined that it has three reporting units and allocates goodwill to the reporting units for the purposes of its annual impairment test.

The Company's annual goodwill impairment test is performed on January 1 each year. No goodwill impairment charges were recorded in the periods presented.

Intangible assets with finite useful lives are amortized on a straight-line basis over the periods benefited. Amortization expense for the customer relationship intangible asset is included in sales and marketing expenses. Amortization expense for technology is included in cost of service revenue.

Warranty Expense

WARRANTY EXPENSE

The Company accrues for estimated product warranty cost upon revenue recognition. Accruals for product warranties are calculated based on the Company's historical warranty experience adjusted for any specific requirements.

Research, Development and Software Costs

RESEARCH & DEVELOPMENT AND SOFTWARE COSTS

Software developed or obtained for internal use in accordance with ASC 350-40, Internal-Use Software (ASC 350-40), is capitalized during the application development stage. In accordance with authoritative guidance, the Company begins to capitalize costs to develop software when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed, and the software will be used as intended. Once the project has been completed, these costs are amortized on a straight - line basis over the estimated useful life of the related asset, generally estimated to be three years. Costs incurred prior to meeting these criteria together with costs incurred for training and maintenance are expensed as incurred and recorded in research and development expense on our consolidated statements of operations. The Company classifies software development costs associated with the development of the Company's products and services as property and equipment. See Note 3 for further details.

Advertising Costs

ADVERTISING COSTS

Advertising costs are expensed as incurred and were $14.5 million, $9.5 million and $8.5 million for the years ended March 31, 2018, 2017 and 2016, respectively.

Foreign Currency Translation

FOREIGN CURRENCY TRANSLATION

The Company has determined that the functional currency of each of its foreign subsidiaries are the subsidiary's local currency. The Company believes this most appropriately reflects the current economic facts and circumstances of the Company's subsidiaries' operations. The assets and liabilities of the subsidiaries are translated at the applicable exchange rate as of the end of the balance sheet period and revenue and expenses are translated at an average rate over the period presented. Resulting currency translation adjustments are recorded as a component of accumulated other comprehensive income or loss within the stockholder's equity.

Business Segments

BUSINESS SEGMENTS

The Company has two reportable segments, 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 chief operating decision makers, the Chief Executive Officer, Chief Financial Officer, and Chief Technology Officer, evaluate performance of the Company and makes decisions regarding allocation of resources based on geographical results.

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.

Concentrations

CONCENTRATIONS

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents, investments and trade accounts receivable. The Company has cash equivalents and investment policies that limit the amount of credit exposure to any one financial institution and restrict placement of these funds to financial institutions evaluated as highly credit-worthy. The Company has not experienced any material losses relating to its investments.

The Company sells its products to business customers and distributors. The Company performs ongoing credit evaluations of its customers' financial condition and generally does not require collateral from its customers. At March 31, 2018 and 2017, no customer accounted for more than 10% of accounts receivable.

The Company purchases all of its hardware products from suppliers that manufacturer the hardware directly. The inability of any supplier to fulfill supply requirements of the Company could materially impact future operating results, financial position or cash flows.

The Company also relies primarily on third-party network service providers to provide telephone numbers and PSTN call termination and origination services for its customers. If these service providers failed to perform their obligations to the Company, such failure could materially impact future operating results, financial position and cash flows.

Fair Values of Financial Instruments

FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal market or the most advantageous market in which it would transact.

The accounting guidance for fair value measurement requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs are inputs that reflect the assumptions market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the factors that market participants would use in valuing the asset or liability developed based on the best information available in the circumstances.

The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value by requiring that the most observable inputs be used when available. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets).
Level 3 applies to assets or liabilities for which fair value is derived from valuation techniques in which one or more significant inputs are unobservable, including the Company's own assumptions.

The estimated fair value of financial instruments is determined by the Company using available market information and valuation methodologies considered to be appropriate. The carrying amounts of the Company's cash and cash equivalents, accounts receivable and accounts payable approximate their fair values due to their short maturities. The Company's investments are carried at fair value.

Accounting for Stock-Based Compensation

ACCOUNTING FOR STOCK-BASED COMPENSATION

The Company accounts for its employee stock options and other stock awards under the provisions of ASC 718 - Stock Compensation. Stock-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized as an expense over the employee's requisite service period (generally the vesting period of the equity grant), net of estimated forfeitures.

To value option grants the Company uses the Black-Scholes option valuation model. Fair value determined using the Black-Scholes option valuation model varies based on assumptions used for the expected stock prices volatility, expected life, risk-free interest rates and future dividend payments. The Company used the historical volatility of its stock over a period equal to the expected life of the options. The expected life assumptions represent the weighted-average period stock-based awards are expecting to remain outstanding. These expected life assumptions were established through the review of historical exercise behavior of stock-based award grants with similar vesting periods. The risk-free interest rates were based on the closing market bid yields of actively traded U.S. treasury securities in the over-the-counter market for the expected term equal to the expected term of the option. The dividend yield assumption is based on the Company's history of not paying dividends.

The Company issued performance stock units (PSUs) to a group of executives with vesting that is contingent on both market performance and continued service during the fiscal year ended March 31, 2018:

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 the Company's common stock performance is below negative 30% relative to the benchmark, no shares will be issued.

The Company issued PSUs to a group of executives with vesting that is contingent on both market performance and continued service during the fiscal year ended March 31, 2017:

These PSUs vest (1) 50% on September 22, 2018 and (2) 50% on September 27, 2019, 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 by 2% of the target numbers. In the event the Company's common stock performance is below negative 30%, relative to the benchmark, no shares will be issued.

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.

Comprehensive Income (Loss)

COMPREHENSIVE (LOSS) INCOME

Comprehensive income (loss), as defined, includes all changes in equity (net assets) during a period. The difference between net income (loss) and comprehensive income (loss) is due to foreign currency translation adjustments and unrealized gains or losses on investments classified as available-for-sale.

Net Income (Loss) Per Share

NET INCOME (LOSS) PER SHARE

Basic net income (loss) per share is computed by dividing net income (loss) available to common stockholders (numerator) by the weighted average number of vested, unrestricted common shares outstanding during the period (denominator). Diluted net income (loss) per share is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method unless their effect is anti-dilutive. Dilutive potential common shares include outstanding stock options and employee restricted purchase rights.

Deferred Rent

DEFERRED RENT

The Company recognizes rent expense on a straight-line basis for all operating lease arrangements with the difference between required lease payments and rent expense recorded as deferred rent. The difference results from rent holidays, rent escalations and tenant improvement allowances, which are amortized over the lease term.

Recently Adopted Accounting Pronouncements

RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS

In November 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-17, Income Taxes - Balance Sheet Classification of Deferred Taxes (Topic 740). This ASU requires all deferred tax liabilities and assets to be presented in the balance sheet as noncurrent. As permitted, the Company early adopted this standard prospectively during the quarter ended June 30, 2016. The adoption of this standard resulted in reclassifying current deferred income tax assets to noncurrent deferred income tax assets and current deferred income tax liabilities to noncurrent deferred income tax liabilities. No prior periods were retrospectively adjusted.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which is intended to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. As a result of the adoption in fiscal year 2018, stock-based compensation excess tax benefits or tax deficiencies will be reflected in the consolidated statement of operations within the provision for income taxes.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230), which provides guidance on how restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The Company elected to early adopt this ASU for fiscal year 2018 and disclosed restricted cash in the amount of $8.1 million in the consolidated balance sheets as of March 31, 2018. No prior periods were retrospectively adjusted.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates the requirement to calculate the implied fair value of goodwill but rather require an entity to record an impairment charge based on the excess of a reporting unit's carrying value over its fair value. This amendment is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company elected to early adopt this ASU for fiscal year 2018. No prior periods were retrospectively adjusted.

Recent Accounting Pronouncements

RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Accounting Standards Codification 606 or ASC 606), which replaces numerous requirements in U.S. GAAP and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. ASC 606 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 in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. It defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates are required within the revenue recognition process than are required under current GAAP (ASC 605).

The new standard permits the use of either the full retrospective or modified retrospective transition method. The Company adopted the new standard effective April 1, 2018 using the modified retrospective method. Under the retrospective method prior period financial information is not revised, but instead a cumulative impact is recorded on the day of adoption with a corresponding offset recorded to stockholder's equity.

Under the new standard, the Company expects in some cases to recognize revenue earlier than under ASC 605 guidance when the customer receives services or equipment for a reduced consideration at the onset of an arrangement, for example the initial month's services or equipment are discounted, as a result of the elimination of contingent revenue guidance. Under ASC 605 guidance, amounts allocated to delivered items are limited to amounts that are not contingent on the provision of future services. The impact of adopting the new standard on the Company's total revenues and deferred revenue is not expected to be material.

With the adoption of ASC 606 the Company also adopted ASC 340-40, Other Assets and Deferred Costs - Contracts with Customers, which requires the deferral of incremental costs of obtaining a customer contract which, under the old guidance, were expensed as incurred. Under the new standard, the Company will defer all incremental sales commission costs and amortize them over the expected period of benefit, which is estimated to be five years. The amortization cost will be charged to sales and marketing costs on the consolidated statements of operations. The Company expects the cumulative impact of these deferred costs to be approximately $35 million to $40 million with a corresponding decrease to accumulated deficit as of April 1, 2018.

There will not be any significant tax impact to the Company's consolidated statements of operations and consolidated balance sheet relating to the adoption of the new standard due to the valuation allowance recorded against to the Company's deferred tax assets.

The Company has established new accounting policies, is implementing processes, and implementing internal controls necessary to support the requirements of the new standard.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires companies to generally recognize on the balance sheet operating and financing lease liabilities and corresponding right-of-use assets. The update also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. The update requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. This amendment is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which provides guidance for measurement and recognition of expected credit losses for financial assets held based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The amendment is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for fiscal years beginning after December 15, 2018. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which provides guidance on how certain cash receipts and cash payments are to be presented and classified in the statement of cash flows. This amendment is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its Consolidated Statements of Cash Flows.

In October 2016, the FASB has issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which provides guidance on how an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This amendment is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements.

In January 2017, the FASB has issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This amendment is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements.

Indemnifications

Indemnifications

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.
