	2. Basis of Presentation and Significant Accounting Policies
	The accompanying condensed consolidated financial statements as of March 31, 2014, and for the three and nine months ended March 31, 2014 and 2013 have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto, included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2013. In the opinion of management, all adjustments (primarily consisting of normal recurring adjustments) considered necessary for a fair statement have been included.
	The condensed consolidated balance sheet at June 30, 2013 has been derived from the audited consolidated financial statements as of that date but does not include all of the information and footnotes included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2013. The results of operations for the three and nine months ended March 31, 2014 are not necessarily indicative of the operating results to be expected for the full fiscal year or any future periods.
	Correction of Prior Period Error
	Subsequent to the issuance of the condensed consolidated financial statements as of and for the three and nine months ended March 31, 2013, the Company determined that the $9.1 million payment of contingent purchase consideration associated with the M5 Networks, Inc. (“M5”) acquisition classified as investing activities in the condensed consolidated statements of cash flows for the nine months ended March 31, 2013 should have been classified as financing activities in the condensed consolidated statements of cash flows for the nine months ended March 31, 2013. Accordingly, the Company corrected the error for the nine months ended March 31, 2013 in the accompanying condensed consolidated financial statements. Net cash used in investing activities for the nine months ended March 31, 2013 originally reported of $14.2 million was corrected to $5.0 million. Net cash provided by financing activities for the nine months ended March 31, 2013 originally reported of $9.4 million was corrected to $0.3 million. The corrections did not affect the net cash provided by operating activities nor the net increase (decrease) in cash and cash equivalents. The Company will also correct the error for the year ended June 30, 2013 in the Company’s Annual Report on Form 10-K for the year ending June 30, 2014. The foregoing corrections are not considered material by the Company.
	Computation of Net Loss per Share
	Basic net loss per share is determined by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is determined by dividing net loss by the weighted average number of common shares used in the basic loss per share calculation plus the number of common shares that would be issued assuming conversion of all potentially dilutive securities outstanding under the treasury stock method. Dilutive securities of 8.3 million and 11.2 million shares were not included in the computation of diluted net loss per share for the three and nine months ended March 31, 2014 and 2013, respectively, because such securities were anti-dilutive.
	Concentration of Credit Risk
	Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, short-term investments and accounts receivable. As of March 31, 2014, all of the Company’s cash, cash equivalents and short-term investments were managed by several financial institutions. Accounts receivable are typically unsecured and are derived from revenue earned from customers. The Company performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses. Accounts receivable from one value-added distributor accounted for 32% of total accounts receivable at March 31, 2014. At June 30, 2013 one value-added distributor accounted for 27% of the total accounts receivable.
	Revenue Recognition
	The Company’s revenue recognition policy from products and services of its premise and hosted segments is included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2013.
	Recent Accounting Pronouncements
		(a)	New Accounting Updates Recently Adopted
	In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (ASU) No. 2011-11, Balance Sheet (Topic 210) - Disclosures about Offsetting Assets and Liabilities (ASU 2011-11), that requires an entity to disclose additional information about offsetting and related arrangements to enable users of the financial statements to understand the effect of those arrangements on the financial position. ASU 2011-11 was adopted by the Company beginning July 1, 2013. The adoption of ASU 2011-11 did not impact disclosures or the Company’s consolidated financial statements.
	In June 2011, the FASB issued ASU No. 2011-5, Comprehensive Income (Topic 220) - Presentation of Comprehensive Income, which requires companies to present the total of comprehensive income (loss), the components of net income (loss), and the components of other comprehensive income (loss) either as a single continuous statement of comprehensive income (loss) or in two separate but consecutive statements. This update eliminates the option to present the components of other comprehensive income (loss) as part of the statement of changes in stockholders’ equity. In December 2011, the FASB deferred the effective date of the specific requirement to present items that are reclassified out of accumulated other comprehensive income (loss) to net income (loss) alongside their respective components of net income (loss) and other comprehensive income (loss). The deferred provision was adopted by the Company beginning July 1, 2013 and did not have an impact on the Company’s consolidated financial statements.
	In July 2012, the FASB issued ASU No. 2012-2, Intangibles - Goodwill and Other (Topic 350) - Testing Goodwill for Impairment (ASU 2012-2), an accounting standard update intended to simplify how an entity tests indefinite-lived intangible assets other than goodwill for impairment by providing entities with an option to perform a qualitative assessment to determine whether further impairment testing is necessary. This accounting standard update was adopted by the Company beginning July 1, 2013 and did not have an impact on the Company's consolidated financial statements.
		(b)	Recent Accounting Standards or Updates Not Yet Effective
	In March 2013, the FASB issued ASU No. 2013-5, Foreign Currency Matters (Topic 830) - an accounting standard update requiring an entity to release into net income the entire amount of a cumulative translation adjustment related to its investment in a foreign entity when as a parent it either sells a part or all of its investment in the foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets within the foreign entity. This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2015. The Company does not expect the adoption of this accounting standard will have a material impact on its consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740) - an accounting standard update that provides explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. Under the new standard update, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, is to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward. This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2015 and applied prospectively with early adoption permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

	The intangible assets that are amortizable have estimated useful lives of two to eight years.
	Research and development costs are expensed as incurred. In accordance with ASC 985-20, Costs of Computer Software to be Sold, Leased, or Marketed, development costs of computer software to be sold, leased, or otherwise marketed are subject to capitalization beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. Such costs are amortized using the straight-line method over the estimated economic life of the product. The Company evaluates the realizability of the assets and the related periods of amortization on a regular basis. Judgment is required in determining when technological feasibility of a product is established as well as its economic life. In most instances, the Company’s products are released soon after technological feasibility has been established; therefore, costs incurred subsequent to achievement of technological feasibility are usually not significant.
	During the nine months ended March 31, 2014, the Company transferred $1.7 million of software development costs related to internal use software acquired from M5 from intangible assets in process to technology. Certain internally developed software also became available for general release to customers during the nine months ended March 31, 2014; at which time, an aggregate of  $2.0 million in software development costs were transferred from intangible assets in process and other to technology in the table above, and the amortization expense is being recognized related to these capitalized software costs. Additionally, during the three and nine months ended March 31, 2013, the Company capitalized $0.4 million and $1.6 million of software development costs related to new products, respectively.
	Amortization of intangible assets for the three months ended March 31, 2014 and 2013 was $2.5 million and $2.4 million, respectively. Amortization of intangible assets for the nine months ended March 31, 2014 and 2013 was $7.5 million and $7.2 million, respectively.

Fair Value Disclosure [Abstract]	'
Fair Value Disclosure	'
	4. Fair Value Disclosure
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. Further, entities are required to maximize the use of observable inputs and minimize the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows:
		•	Level 1 — Quoted prices in active markets for identical assets or liabilities.
		•	Level 2 — Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means.
		•	Level 3 — Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities, and reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances.
	The tables below set forth the Company’s financial instruments and liabilities measured at fair value on a recurring basis (in thousands):
			31-Mar-14

	Liabilities:
	Acquisition-related consideration		$	3,577		$	-	$	3,577	$	-
	The above table excludes $37.5 million of cash balances on deposit at banks.
	The foreign exchange forward contracts outstanding as of March 31, 2014 are entered into by the Company on the last business day of the period. Given the relatively short duration such contracts are outstanding in relation to changes in potential market rates, the change in the fair value is not material and is not reflected either as an asset or a liability.
	Money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets. Short-term investments are classified within Level 2 of the fair value hierarchy because they are valued based on other observable inputs, including broker or dealer quotations, or alternative pricing sources. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from independent pricing services. Non-binding quotes are based on proprietary valuation models prepared by independent pricing services. These models use algorithms based on inputs such as observable market data, quoted market prices for similar instruments, historical pricing trends of a security as relative to its peers, internal assumptions of the independent pricing service and statistically supported models. The Company corroborates the reasonableness of non-binding quotes received from the independent pricing service by comparing them to the (a) actual experience gained from the purchases and redemption of investment securities, (b) quotes received on similar securities obtained when purchasing securities and (c) monitoring changes in ratings of similar securities and the related impact on the fair value. The types of instruments valued based on other observable inputs include corporate notes and commercial paper and U.S. Government agency securities. The Company reviewed financial and non-financial assets and liabilities and concluded that there were no other-than-temporary impairment charges during the three and nine months ended March 31, 2014 and 2013, respectively. The Company reviews the fair value hierarchy on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels of certain securities within the fair value hierarchy. The Company recognizes transfers into and out of levels within the fair value hierarchy as of the date in which the actual event or change in circumstances that caused the transfer occurs. There were no transfers between Level 1 and Level 2 of the fair value hierarchy for any of the periods presented.
	The Company measures the fair value of outstanding debts for disclosure purposes on a recurring basis. As of March 31, 2014 and June 30, 2013, long-term debt of $4.1 million and $29.0 million, respectively, is reported at amortized cost. This outstanding debt is classified at Level 2 as it is not actively traded and is valued using a discounted cash flow model that uses observable market inputs. Based on the discounted cash flow model, the fair value of the outstanding debt approximates amortized cost.
	The purchase consideration for the Company’s acquisition of M5 included a contingent portion ranging from zero to $13.7 million and was subject to the achievement of certain revenue targets. These revenue targets were met in full on December 31, 2012, and as such, $10.0 million was paid in March 2013 and the remaining $3.7 million was paid in January 2014.
	The change in the fair value of the Company’s purchase consideration liability is as follows (in thousands):
			Fair Value
	As of June 30, 2013		$	3,577
	Add: Change in fair value of purchase consideration			111
	Less: Payment of purchase consideration			(3,688	)
	As of March 31, 2014		$	-
	Assets and Liabilities That Are Measured at Fair Value on a Nonrecurring Basis
	Non-financial assets such as goodwill, intangible assets, and property, plant, and equipment are evaluated for impairment and adjusted to fair value using Level 3 inputs, only when impairment is recognized. Fair values are considered Level 3 when management makes significant assumptions in developing a discounted cash flow model based upon a number of considerations including projections of revenues, earnings and a discount rate. In addition, in evaluating the fair value of goodwill impairment, further corroboration is obtained using the Company’s market capitalization. There were no indicators of impairment in the three and nine months ended March 31, 2014 that required a nonrecurring fair value analysis to be performed on non-financial assets.

	5. Line of credit
	On March 15, 2012, the Company entered into a secured credit agreement (the “Credit Facility”).  The Credit Facility was amended on December 4, 2012. The Credit Facility includes a revolving loan facility for an aggregate principal amount not exceeding $50.0 million. The Credit Facility matures on the fifth anniversary of its closing (March 15, 2017) and is payable in full upon maturity. The amounts borrowed and repaid under the Credit Facility are available for future borrowings.  The borrowings under the Credit Facility accrue interest either (at the election of the Company) at (i) the London interbank offered rate then in effect, plus a margin of between 2.00% and 2.50%, which is based on the Company’s consolidated EBITDA (as defined in the Credit Facility), or (ii) the higher of (a) the bank’s publicly-announced prime rate then in effect and (b) the federal funds rate plus 0.50%, in each case of (a) or (b), plus a margin of between 0.00% and 0.50%, which will be based upon the Company’s consolidated EBITDA.  The Company also pays annual commitment fees during the term of the Credit Facility which varies depending on the Company’s consolidated EBITDA. The Credit Facility is secured by substantially all of the Company’s assets. The amounts borrowed are recorded as long-term debt, net of the financing costs, in the Company’s consolidated financial statements. As of March 31, 2014, the Company had an additional $45.7 million available for borrowing under the Credit Facility.
	The Credit Facility contains customary affirmative and negative covenants, including compliance with financial ratios and metrics. The Credit Facility and the related amendment requires the Company to maintain a minimum ratio of liquidity to its indebtedness (each as defined in the Credit Facility) and varying amounts of Liquidity and Consolidated EBITDA specified in the Credit Facility throughout the term of the agreement. The Company was in compliance with all such covenants as of March 31, 2014.
	For the three and nine months ended March 31, 2014, the Company paid interest at an approximate rate of 2.4% per annum. As of March 31, 2014, the Company had $4.3 million outstanding under the Credit Facility. The Company amortizes deferred financing costs to interest expense on a straight-line basis over the term of the debt.

	6. Income Taxes
	The Company recorded an income tax provision of $0.3 million and $0.7 million for the three and nine months ended March 31, 2014, respectively and $0.1 million and $0.3 million for the three and nine months ended March 31, 2013, respectively.
	The tax provision of $0.3 million and $0.7 million determined for the three and nine months ended March 31, 2014 is primarily the result of income tax provisions for federal alternative minimum tax, tax provisions for profitable foreign jurisdictions based upon income earned during the period and state tax provisions including certain states that are determined on a basis other than income earned. No income tax benefit was accrued for jurisdictions where the Company anticipates incurring a loss during the full fiscal year as the related deferred tax assets were fully offset by a valuation allowance.
	The tax provision determined for the three and nine months ended March 31, 2013 is primarily the result of income tax provisions for profitable foreign jurisdictions based upon income earned during this period and tax provisions for certain states that are determined on a basis other than income earned. The tax provision for the nine months ended March 31, 2013 is also as a result of an increase in the valuation allowance recorded against deferred tax assets established upon the acquisition of M5 Networks.
	The Company maintains liabilities for uncertain tax positions. As of March 31, 2014 and June 30, 2013, the Company’s total amount of unrecognized tax benefits was $4.0 million and $4.1 million, respectively. Of the total of $4.0 million of unrecognized tax benefit as of March 31, 2014, none, if recognized, would impact the effective tax rate. The Company does not expect its unrecognized tax benefits to change materially over the next 12 months.
	The “American Taxpayer Relief Act of 2012” (the “2012 Tax Act”) was enacted in January 2013. The 2012 Tax Act extended certain tax provisions that had previously expired under the “Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010”. The 2012 Tax Act extended the Research and Development credit for qualifying activities through December 31, 2013 and also extended the 50% bonus depreciation provisions on property acquired through December 31, 2013.
	While management believes that the Company has adequately provided for all tax positions, amounts asserted by tax authorities could be greater or less than the Company’s current position. Accordingly, the Company’s provisions for federal, state and foreign tax related matters to be recorded in the future may change as revised estimates are made or as the underlying matters are settled or otherwise resolved.
	The Company’s primary tax jurisdiction is in the United States. For federal and state tax purposes, the tax years 2001 through 2013 remain open and subject to tax examination by the appropriate federal or state taxing authorities.

	During the three and nine months ended March 31, 2014, the Company recorded non-cash stock-based compensation expense of $1.7 million and $5.9 million, respectively. During the three and nine months ended March 31, 2013, the Company recorded non-cash stock-based compensation expense of $2.0 million and $8.9 million, respectively.
	Compensation expense is recognized only for the portion of stock options that are expected to vest, assuming an expected forfeiture rate in determining stock-based compensation expense, which could affect the stock-based compensation expense recorded if there is a significant difference between actual and estimated forfeiture rates. As of March 31, 2014, total unrecognized compensation cost related to stock-based options and awards granted to employees and non-employee directors was $8.8 million. This cost will be amortized on a ratable basis over a weighted-average vesting period of approximately 2.6 years.

	In January 1997, the Board of Directors and stockholders adopted the 1997 stock option plan (the “1997 Plan”) which, as amended, provided for granting incentive stock options (“ISOs”) and nonqualified stock options (“NSOs”) for shares of common stock to employees, directors, and consultants of the Company. This plan was terminated in January 2007 for new issuances.
	In February 2007, the Company adopted the 2007 Equity Incentive Plan (the “2007 Plan”) which, as amended, provides for grants of ISOs, NSOs, restricted stock units (“RSUs”) and restricted stock awards (“RSAs”) to employees, directors and consultants of the Company. Options granted generally vest ratably over four years from the date of grant. The 2007 Plan provides that the options shall be exercisable over a period not to exceed ten years. Five million shares of common stock were initially reserved for future issuance in the form of stock options, restricted stock awards or units, stock appreciation rights and stock bonuses. Pursuant to the provisions under the 2007 Plan, each year, the number of shares in the reserve shall be increased by the provisions set forth in the 2007 Plan, subject to approval by the Company’s Board of Directors. The Company’s Board of Directors increased the number of shares authorized and reserved for issuance under the 2007 Plan during the three months ended March 31, 2014 and 2013, by 3.1 million shares and 2.9 million shares, respectively.

	12. Litigation, Commitments, Contingencies and Leases
	Litigation — At March 31, 2014, the Company is involved in litigation relating to claims arising out of the ordinary course of business or otherwise. Any litigation, regardless of outcome, is costly and time-consuming, can divert the attention of management and key personnel from business operations, deter distributors from selling the Company’s products and dissuade potential customers from purchasing the Company’s products. The Company defends itself vigorously against any such claims. Due to the uncertainty surrounding the litigation process, the Company is unable to estimate a range of loss, if any, at this time, however the Company does not believe a material loss is probable.
	In addition, on March 21, 2013, the Company provided Fortis Advisors LLC, as representative of the former shareholders of M5 Networks, with a Claim Certificate disclosing certain claims for indemnification under the January 31, 2012 Agreement and Plan of Reorganization between M5 and the Company (the “Purchase Agreement”).  Thereafter, the Company and Fortis engaged in negotiations in an attempt to resolve the indemnification claims asserted by the Company.  In September 2013, the Company received notice of commencement of an arbitration proceeding by Fortis on behalf of the former shareholders of M5.  Through the arbitration, Fortis seeks a declaration that the Company’s claims for indemnification are precluded.  On October 11, 2013, the Company served its response, denying all of Fortis’ allegations and asserting counterclaims for breach of the Purchase Agreement and declaratory relief.
	Indemnification asset — At March 31, 2014, the Company had a $5.5 million indemnification asset. The indemnification asset represents reimbursement the Company reasonably expects to receive from the escrow funds, currently held by a financial institution, pursuant to the M5 purchase agreement.
	Leases — The Company leases its facilities under noncancelable operating leases which expire at various times through 2023. The leases provide for the lessee to pay all costs of utilities, insurance, and taxes. Future minimum lease payments under the noncancelable capital and operating leases as of March 31, 2014, are as follows (in thousands):
	Years Ending June 30,	Operating		Capital

	Capital lease obligation, net of current portion			$	78
	The operating lease obligations noted in the table above have not been reduced by non-cancellable sublease rentals of $0.5 million.
	The current portion of the capital leases is included in accrued liabilities and other on the condensed consolidated balance sheet. The non-current portion of the capital leases is included in the other long-term liabilities on the consolidated balance sheet. Lease obligations for the Company’s foreign offices are denominated in foreign currencies, which were converted in the above table to U.S. dollars at the interbank exchange rate on March 31, 2014.
	Rent expense for the three months ended March 31, 2014 and 2013 was $1.1 million and $1.0 million, respectively and was $3.1 million and $2.8 million, for the nine months ended March 31, 2014 and 2013, respectively.
	Purchase commitments — The Company had purchase commitments with contract manufacturers for inventory totaling approximately $29.5 million as of March 31, 2014 and $24.0 million as of June 30, 2013.
	Letters of credit — Outstanding letters of credit maintained by the Company totaled $635,000 as of March 31, 2014.
	Indemnification — Under the indemnification provisions of the Company’s customer agreements, the Company agrees to indemnify and defend its customers against infringement of any patent, trademark, or copyright of any country or the misappropriation of any trade secret, arising from the customers’ legal use of the Company’s services. The exposure to the Company under these indemnification provisions is generally limited to the total amount paid by the customers under pertinent agreements. However, certain indemnification provisions potentially expose the Company to losses in excess of the aggregate amount received from the customer.
	The Company also has entered into customary indemnification agreements with each of its officers and directors. The Company also has indemnification obligations to the underwriters of its initial public offering pursuant to the underwriting agreement executed in connection with that offering.

	14. Derivative Instruments and Hedging Activities
	In the normal course of business, the Company is exposed to fluctuations in interest rates and the exchange rates associated with foreign currencies. During the three months ended March 31, 2014, the Company used derivative instruments to reduce the volatility of earnings associated with changes in foreign currency exchange rates. The Company used foreign exchange forward contracts to mitigate the gains and losses generated from the re-measurement of certain foreign monetary assets and liabilities, primarily including cash balances, third party accounts receivable and intercompany transactions recorded on the balance sheet. These derivatives are not designated and do not qualify as hedge instruments. Accordingly, changes in the fair value of these instruments are recognized in other income and expenses during the period of change. The fair values recorded during the three and nine months ended March 31, 2014 and 2013 were not material since these contracts were entered into on the last day of the period. These derivatives have maturities of approximately one month.
	The following table presents the gross notional value of all of the Company’s foreign exchange forward contracts outstanding as of March 31, 2014 (in thousands):
		31-Mar-14
		Local Currency		Notional Contract
		Amount		Amount (USD)

	British pound	£	2,670		4,399
	Euro	€	380		518
	Total			$	6,497
	No such contracts were outstanding as of June 30, 2013.

Correction of Prior Period Error	'
	Correction of Prior Period Error
	Subsequent to the issuance of the condensed consolidated financial statements as of and for the three and nine months ended March 31, 2013, the Company determined that the $9.1 million payment of contingent purchase consideration associated with the M5 Networks, Inc. (“M5”) acquisition classified as investing activities in the condensed consolidated statements of cash flows for the nine months ended March 31, 2013 should have been classified as financing activities in the condensed consolidated statements of cash flows for the nine months ended March 31, 2013. Accordingly, the Company corrected the error for the nine months ended March 31, 2013 in the accompanying condensed consolidated financial statements. Net cash used in investing activities for the nine months ended March 31, 2013 originally reported of $14.2 million was corrected to $5.0 million. Net cash provided by financing activities for the nine months ended March 31, 2013 originally reported of $9.4 million was corrected to $0.3 million. The corrections did not affect the net cash provided by operating activities nor the net increase (decrease) in cash and cash equivalents. The Company will also correct the error for the year ended June 30, 2013 in the Company’s Annual Report on Form 10-K for the year ending June 30, 2014. The foregoing corrections are not considered material by the Company.
Computation of Net Loss per Share	'
	Computation of Net Loss per Share
	Basic net loss per share is determined by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is determined by dividing net loss by the weighted average number of common shares used in the basic loss per share calculation plus the number of common shares that would be issued assuming conversion of all potentially dilutive securities outstanding under the treasury stock method. Dilutive securities of 8.3 million and 11.2 million shares were not included in the computation of diluted net loss per share for the three and nine months ended March 31, 2014 and 2013, respectively, because such securities were anti-dilutive.
Concentration of Credit Risk	'
	Concentration of Credit Risk
	Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash, cash equivalents, short-term investments and accounts receivable. As of March 31, 2014, all of the Company’s cash, cash equivalents and short-term investments were managed by several financial institutions. Accounts receivable are typically unsecured and are derived from revenue earned from customers. The Company performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses. Accounts receivable from one value-added distributor accounted for 32% of total accounts receivable at March 31, 2014. At June 30, 2013 one value-added distributor accounted for 27% of the total accounts receivable.
Revenue Recognition	'
	Revenue Recognition
	The Company’s revenue recognition policy from products and services of its premise and hosted segments is included in the Company’s Annual Report on Form 10-K and 10-K/A for the fiscal year ended June 30, 2013.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
		(a)	New Accounting Updates Recently Adopted
	In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (ASU) No. 2011-11, Balance Sheet (Topic 210) - Disclosures about Offsetting Assets and Liabilities (ASU 2011-11), that requires an entity to disclose additional information about offsetting and related arrangements to enable users of the financial statements to understand the effect of those arrangements on the financial position. ASU 2011-11 was adopted by the Company beginning July 1, 2013. The adoption of ASU 2011-11 did not impact disclosures or the Company’s consolidated financial statements.
	In June 2011, the FASB issued ASU No. 2011-5, Comprehensive Income (Topic 220) - Presentation of Comprehensive Income, which requires companies to present the total of comprehensive income (loss), the components of net income (loss), and the components of other comprehensive income (loss) either as a single continuous statement of comprehensive income (loss) or in two separate but consecutive statements. This update eliminates the option to present the components of other comprehensive income (loss) as part of the statement of changes in stockholders’ equity. In December 2011, the FASB deferred the effective date of the specific requirement to present items that are reclassified out of accumulated other comprehensive income (loss) to net income (loss) alongside their respective components of net income (loss) and other comprehensive income (loss). The deferred provision was adopted by the Company beginning July 1, 2013 and did not have an impact on the Company’s consolidated financial statements.
	In July 2012, the FASB issued ASU No. 2012-2, Intangibles - Goodwill and Other (Topic 350) - Testing Goodwill for Impairment (ASU 2012-2), an accounting standard update intended to simplify how an entity tests indefinite-lived intangible assets other than goodwill for impairment by providing entities with an option to perform a qualitative assessment to determine whether further impairment testing is necessary. This accounting standard update was adopted by the Company beginning July 1, 2013 and did not have an impact on the Company's consolidated financial statements.
		(b)	Recent Accounting Standards or Updates Not Yet Effective
	In March 2013, the FASB issued ASU No. 2013-5, Foreign Currency Matters (Topic 830) - an accounting standard update requiring an entity to release into net income the entire amount of a cumulative translation adjustment related to its investment in a foreign entity when as a parent it either sells a part or all of its investment in the foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets within the foreign entity. This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2015. The Company does not expect the adoption of this accounting standard will have a material impact on its consolidated financial statements.
	In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740) - an accounting standard update that provides explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. Under the new standard update, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, is to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward. This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2015 and applied prospectively with early adoption permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.
