Description of the Business and Basis of Presentation	'

	1. Description of the Business and Basis of Presentation

	Throughout these condensed consolidated financial statements, Mavenir Systems, Inc. is referred to as “Mavenir,” the “Company,” “we,” “us” and “our.”

	Description of Business

	Mavenir was originally formed as a limited liability company on April 26, 2005. We were incorporated under the laws of Texas in August 2005, and subsequently incorporated under the laws of Delaware in March 2006.

	We are a leading provider of software-based telecommunications networking solutions that enable mobile service providers to deliver internet protocol (IP)-based voice, video, rich communication and enhanced messaging services to their subscribers globally. Our solutions deliver Rich Communication Suite (“RCS”)-based services, which enable enhanced mobile communications such as group text messaging, multi-party voice or video calling and live video streaming as well as the exchange of files or images, over existing 2G and 3G networks as well as next generation 4G Long Term Evolution (“LTE”) networks. Our solutions also deliver voice services over LTE technology and wireless (“Wi-Fi”) networks known respectively as Voice over LTE (“VoLTE”) and Voice over Wi-Fi (“VoWi-Fi”).

	We are headquartered in Richardson, Texas, and have research and development personnel located at our wholly-owned subsidiaries in China and India. Additionally, we have a sales and operations presence in the Asia Pacific (“APAC”) and the Europe, Middle East and Africa (“EMEA”) regions.

	Basis of Presentation and Consolidation

	The unaudited interim financial statements have been prepared on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly our consolidated financial position as of June 30, 2014, and our results of operations and cash flows for the three and six months ended June 30, 2014 and 2013. We have omitted certain information and disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) pursuant to those rules and regulations, although we believe that the disclosures we have made are adequate to make the information presented not misleading. The results of operations for the three and six months ended June 30, 2014 are not necessarily indicative of the results to be expected for the year ending December 31, 2014, or for any other future annual or interim periods. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013, filed with the Securities and Exchange Commission on February 21, 2014.

	Reclassifications

	Certain prior year amounts have been reclassified to conform to current year presentation. Specifically, the beginning balance of our uncertain tax positions presented in Note 10 is now presented gross, per Financial Accounting Standard Board (“FASB”) Accounting Standards Codification (“ASC”) 740, Income Taxes. There was no change to the presentation on the condensed consolidated balance sheet.

	Use of Estimates

	The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from management’s estimates.



	Revision of Prior Period Financial Statements and Out-of-Period Adjustment

	During our review of the three months ended March 31, 2014, we identified a non-cash error that originated in prior periods. The error related to performance-based warrants issued to a channel partner in 2008, earned in 2011 and exercised in April of 2014. The achievement of the performance milestone occurred in 2011 and would have resulted in a reduction to revenue of $1.3 million in 2011. We assessed the materiality of this error in accordance with the SEC guidance on considering the effects of prior period misstatements based on an analysis of quantitative and qualitative factors. Based on this analysis, we determined that the error was immaterial to the prior reporting periods affected and, therefore, amendments of reports previously filed with the SEC were not required. However, we have concluded that correcting the error in our 2014 financial statements would materially impact our results for the quarter ended March 31, 2014 and the year ending December 31, 2014. Accordingly, we have reflected the correction of this prior period error in the period in which it originated and revised our consolidated balance sheet as of December 31, 2013, as presented in this Quarterly Report on Form 10-Q. In addition, a reduction to accumulated deficit will be reflected as an adjustment to the beginning balance for the earliest year presented in the financial statements included in our Annual Report on Form 10-K for the year ending December 31, 2014.

	The effect of the immaterial correction on the consolidated balance sheet as of December 31, 2013 is as follows (in thousands):



		As Reported			Correction			As Revised
	Other shareholders’ equity	$	1,020		$	—		$	1,020
	Additional paid-in capital		153,878			1,320			155,198
	Accumulated deficit		(110,867	)		(1,320	)	$	(112,187	)

	2. Summary of Significant Accounting Policies and New Accounting Pronouncements

	Significant Accounting Policies

	Our significant accounting policies and others are presented in our Annual Report on Form 10-K for the year ended December 31, 2013, filed with the SEC on February 21, 2014. The policies include significant estimates made by management using information available at the time the estimates are made. However, these estimates could change materially if different information or assumptions were used.

	New Accounting Pronouncements

	In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers: Topic 606” (“ASU 2014-09”). ASU 2014-09 will enhance comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets, reduce the number of requirements which must be considered in recognizing revenue, improve disclosure to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized, and provide guidance for transactions that are not currently addressed comprehensively. The standard is effective for fiscal years beginning after December 15, 2016, and interim periods therein, and does not allow for early adoption. Entities have the option of using either a full retrospective or modified retrospective approach for the adoption of the standard. The Company has not yet begun the evaluation of the impact that the standard will have on its consolidated financial statements and has not yet selected a transition method.

Fair Value Measurements	Jun. 30, 2014
Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'

	3. Fair Value Measurements

	The accounting guidance for fair value measurements establishes a three-tier fair value hierarchy, categorizing the inputs used to measure fair value.



	The hierarchy can be described as follows:

	Level 1—Observable inputs, such as quoted prices in active markets,

	Level 2—Inputs other than the quoted prices in active markets that are observable either directly or indirectly, or

	Level 3—Unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions.

	This hierarchy requires us to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. We evaluate transfers between levels at the end of each reporting period. There were no transfers of assets or liabilities between Level 1 and Level 2 during the three and six months ended June 30, 2014 and 2013 or for the year ended December 31, 2013.

	Our financial instruments consist primarily of cash and cash equivalents, billed accounts receivable, accounts payable and debt. The carrying amounts of financial instruments, other than the debt instruments, are representative of their fair values due to their short maturities. Our debt agreements are considered level 2 instruments and bear interest at market rates and thus management believes their carrying amounts approximate fair value.

	We do not have any other financial or non-financial assets or liabilities that would be characterized as Level 2 or Level 3 instruments.

	Silicon Valley Bank Subordinated and Senior Loans

	On October 18, 2012, we entered into loan agreements with Silicon Valley Bank (“SVB”). Under the agreements, we obtained two loans totaling $32.5 million (the “Old SVB Loans”). In February 2013, we amended the Old SVB Loans to join certain of our subsidiaries, including our non-U.S. subsidiaries, as co-borrowers. We also amended our minimum tangible net worth covenant. The Old SVB Loans included a $22.5 million Senior Loan (“Senior Loan”) secured by substantially all of our assets, including intellectual property. The Senior Loan had a three-year term at a floating rate of 1% above the U.S. prime rate, subject to a minimum interest rate of 4.25%. Under the terms of the agreement, we could draw up to 80% of eligible trade receivables up to $15.0 million, with the remaining $7.5 million generally available for working capital and cash management purposes. We also obtained a $10.0 million Subordinated Loan, also secured by substantially all of our assets including intellectual property that had a three-year term at a fixed rate of 11%. The Old SVB Loans were replaced by an amended and restated loan and security agreement (“Amended and Restated Agreement”) that we entered into with SVB on March 6, 2014, as discussed below.

	On March 6, 2014 we entered into an Amended and Restated Agreement with SVB to replace our $22.5 million Senior Loan facility with SVB. The Amended and Restated Agreement includes a five-year term loan of $25.0 million (“Term Loan”), a $15.0 million secured revolving line of credit (“Revolver”) and a $5 million secured line for letters of credit, foreign exchange and cash management services. The Term Loan has an initial floating interest rate of 2.75% above the U.S. prime rate, subject to a minimum interest rate of 4.25% and is secured by substantially all of our assets, including intellectual property. At June 30, 2014, the interest rate was 6.0%. After the achievement of the one of the two performance triggers described in the following sentence, the interest rate will be reduced to 2.25% above the U.S. prime rate; after the achievement of the second performance trigger the interest rate will be further reduced to 1.75% above the U.S. prime rate. The performance triggers are the following: (i) our achievement, on a consolidated basis, of positive EBITDA (as defined in the loan agreement) for two consecutive fiscal quarters, and (ii) the completion of an equity offering resulting in net proceeds to the Company of at least $50 million. The Term Loan provides for monthly payments of interest only until April 1, 2015; thereafter we are required to repay the outstanding principal amount in 48 monthly installments. The Term Loan has a maturity of March 1, 2019. If we prepay the Term Loan within one year of the Amended and Restated Loan Agreement, we will have to pay a prepayment premium of $250,000; thereafter, the Term Loan may be prepaid without penalty.

	Under the Revolver, we may draw up to 80% of eligible domestic trade receivables, 70% of eligible foreign trade receivables and 35% of eligible accrued but unbilled accounts up to a maximum of $15.0 million. The Revolver has a three-year term and bears interest at a floating interest rate of 1% above the U.S. prime rate, subject to a minimum interest rate of 4.25% and is secured by substantially all of our assets, including intellectual property. We are also required to pay an unused facility fee, monthly in arrears, of 0.25% per annum of the unused amount of the Revolver. The Revolver may be prepaid at any time without penalty. As of June 30, 2014, we had no borrowings outstanding on the Revolver and had $15.0 million available.

	As of March 5, 2014, we had approximately $0.3 million in deferred costs and $0.2 million in debt discount related to the Old SVB Loans on our condensed consolidated balance sheet. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 470, Debt (“ASC 470”), we recorded a $0.3 million loss on early extinguishment of debt related to the Amended and Restated Agreement.



	The Amended and Restated Agreement contains certain restrictive covenants, and requires us to maintain a minimum liquidity ratio and other earnings related amounts as defined in the Amended and Restated Agreement. At June 30, 2014, we were in compliance with all covenants applicable under the Amended and Restated Agreement. The Amended and Restated Agreement also contains usual and customary events of default, the occurrence of which may result in all outstanding amounts under the loan agreements becoming due and payable immediately, and they also impose an interest penalty of an additional 5% above the otherwise applicable interest rate at any time when an event of default is continuing. As of June 30, 2014, we were in compliance with all covenants under the Amended and Restated Agreement.

	Silver Lake Waterman Growth Capital Loan

	On March 5, 2014, we repaid the balance of our $15.0 million subordinated term loan (“Silver Lake Loan”) with Silver Lake Waterman Fund (“Silver Lake”) using funds from our initial public offering.

	As of March 5, 2014, we had approximately $0.2 million in deferred costs and $1.3 million in debt discount related to the Silver Lake Loan on our condensed consolidated balance sheet. The entire $1.5 million was recognized during the six months ended June 30, 2014, as a loss on early extinguishment of debt related to the payoff of the Silver Lake Loan on March 5, 2014.

	Equity Compensation Plans

	We have two stock option plans: the Amended and Restated 2005 Stock Plan (the “2005 Plan”), and the Amended and Restated 2013 Equity Incentive Plan (the “2013 Plan”). In January 2013, we terminated the 2005 Plan and provided that no further stock awards were to be granted under the 2005 Plan and adopted the 2013 Plan as a continuation of and successor to the 2005 Plan. Upon our initial public offering (“IPO”), all shares that were reserved under the 2005 Plan but not issued were assumed by the 2013 Plan. All outstanding stock awards under the 2005 Plan continue to be governed by the existing terms. Under the 2013 Plan, we have the ability to issue incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units, performance units and/or performance shares. Additionally, the 2013 Plan provides for the grant of performance cash awards to employees, directors and consultants. Stock options are granted at a price per share not less than the fair value at date of grant. Stock options granted to date generally vest over a four-year period with 25% vesting at the end of one year and the remaining vesting monthly thereafter. Stock options granted generally are exercisable up to 10 years from the date of grant.

	At June 30, 2014, there were 1,023,550 common shares available for future grants under the 2013 Plan.



	To determine the weighted average fair value of stock options granted, we used the Black-Scholes option-pricing model with the following weighted average assumptions during the periods presented:



		Three months ended						Six months ended
		June 30,						June 30,
		2014			2013			2014			2013
	Expected dividend yield		0	%		0	%		0	%		0	%
	Risk-free interest rate (U.S. Treasury)		2	%		2	%		2	%		2	%
	Expected term		6.3 years			6.3 years			6.3 years			6.3 years

	We calculate basic net (loss) per share by dividing net (loss) attributable for the period by the weighted average number of shares of common stock outstanding during the period. Diluted, net (loss) per share is computed by giving effect to all potential weighted average diluted common stock, including options and warrants, using the treasury stock method.

	10. Income Taxes

	We base our provision for income taxes in our interim condensed consolidated financial statements on estimated annual effective tax rates in the tax jurisdictions where we operate. We monitor the assumptions used in estimating the annual effective tax rate and make adjustments, if required, throughout the year. If actual results differ from the assumptions used in estimating our annual effective income tax rate, future income tax expense could be materially affected. For the three and six months ended June 30, 2014, total income tax expense is approximately $0.4 million and $0.5 million on a worldwide basis compared with total income tax expense of approximately $1.2 million and $1.6 million for the three and six months ended June 30, 2013. The difference is due primarily to discrete items recognized in the current quarter related to foreign taxes and the benefit realized from changes in our uncertain tax positions as described below.



	We apply a two-step process for the evaluation of uncertain income tax positions based on a “more likely than not” threshold to determine if a tax position will be sustained upon examination by the taxing authorities. The recognition threshold in step one permits the benefit from an uncertain position to be recognized only if it is more likely than not, or 50% assured that the tax position will be sustained upon examination by the taxing authorities. The measurement methodology in step two is based on “cumulative probability,” resulting in the recognition of the largest amount that is greater than 50% likely of being realized upon settlement with the taxing authority.

	During the current quarter, the company completed a review of certain of its internal accounts and pricing and determined that it has reduced tax exposures, on an overall basis, primarily related to the way we account for certain intercompany transactions relating to management fees, sales support services, research and development services, license fees, or other development costs. These services are offered to and received from various related companies resulting in payables and receivables which are disregarded for our US GAAP financial reporting but are recognized for tax purposes in several jurisdictions. Therefore, the tax treatment of the intercompany transactions has been analyzed in each entity’s jurisdiction and exposures were identified and quantified by jurisdiction. The net effect of the adjustment is approximately $0.3 million and is recorded as a decrease to income tax expense in the current period. The resulting balance of our uncertain tax positions is depicted in the table below, on a gross basis, as of June 30, 2014 (in thousands):



	Beginning Balance at January 1, 2014	$	4,207
	Additions to unrecognized tax benefits taken during the period		—
	Additions to unrecognized tax benefits as a result of positions taken in prior periods		2,129
	Decrease in unrecognized tax benefits relating to settlements with taxing authorities		—
	Reductions to unrecognized tax benefits as a result of a lapse of the applicable statute of limitations		—
	Reduction to unrecognized tax benefits as a result of positions taken during the period		(2,235	)

	Ending Balance at June 30, 2014	$	4,101


	Total deferred tax assets of approximately $2.9 million were available for offset on identified uncertain tax positions; additional interest and penalties of approximately $1.6 million not reflected on the above roll forward are booked as a component of the total liability for uncertain tax positions. The net impact of the deferred tax asset offsets and interest and penalties result in a net uncertain tax position liability of approximately $2.8 million on our balance sheet.

	Our net deferred tax asset is offset by a valuation allowance since such amounts are not considered realizable on a more-likely-than-not basis. We have not accrued a provision for income taxes on undistributed earnings of approximately $12.0 million of certain non-U.S. subsidiaries, as of June 30, 2014 since such earnings are considered to be reinvested indefinitely. If the earnings were distributed, we would be subject to U.S. federal income and foreign withholding taxes. Determination of an unrecognized deferred income tax liability with respect to such earnings is not practicable.

	11. Segment and Geographic Information

	Operating segments are defined as components of an enterprise in which separate financial information is available that is evaluated regularly by the chief operating decision makers, in deciding how to allocate resources and in assessing performance. Our chief operating decision-makers (i.e., our chief executive officer and his direct reports) review financial information presented on a condensed consolidated basis, accompanied by disaggregated information about revenues by geographic region for purposes of allocating resources and evaluating financial performance. We have concluded that we operate in one segment and have provided the required enterprise-wide disclosures.

Accounting Policies [Abstract]

Basis of Presentation and Consolidation

The unaudited interim financial statements have been prepared on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly our consolidated financial position as of June 30, 2014, and our results of operations and cash flows for the three and six months ended June 30, 2014 and 2013. We have omitted certain information and disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) pursuant to those rules and regulations, although we believe that the disclosures we have made are adequate to make the information presented not misleading. The results of operations for the three and six months ended June 30, 2014 are not necessarily indicative of the results to be expected for the year ending December 31, 2014, or for any other future annual or interim periods. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013, filed with the Securities and Exchange Commission on February 21, 2014.

Use of Estimates

The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from management’s estimates.

Revision of Prior Period Financial Statements and Out-Of-Period Adjustment

Reclassifications

Certain prior year amounts have been reclassified to conform to current year presentation. Specifically, the beginning balance of our uncertain tax positions presented in Note 10 is now presented gross, per Financial Accounting Standard Board (“FASB”) Accounting Standards Codification (“ASC”) 740, Income Taxes. There was no change to the presentation on the condensed consolidated balance sheet.

Revision of Prior Period Financial Statements and Out-of-Period Adjustment

During our review of the three months ended March 31, 2014, we identified a non-cash error that originated in prior periods. The error related to performance-based warrants issued to a channel partner in 2008, earned in 2011 and exercised in April of 2014. The achievement of the performance milestone occurred in 2011 and would have resulted in a reduction to revenue of $1.3 million in 2011. We assessed the materiality of this error in accordance with the SEC guidance on considering the effects of prior period misstatements based on an analysis of quantitative and qualitative factors. Based on this analysis, we determined that the error was immaterial to the prior reporting periods affected and, therefore, amendments of reports previously filed with the SEC were not required. However, we have concluded that correcting the error in our 2014 financial statements would materially impact our results for the quarter ended March 31, 2014 and the year ending December 31, 2014. Accordingly, we have reflected the correction of this prior period error in the period in which it originated and revised our consolidated balance sheet as of December 31, 2013, as presented in this Quarterly Report on Form 10-Q. In addition, a reduction to accumulated deficit will be reflected as an adjustment to the beginning balance for the earliest year presented in the financial statements included in our Annual Report on Form 10-K for the year ending December 31, 2014.

The effect of the immaterial correction on the consolidated balance sheet as of December 31, 2013 is as follows (in thousands):

Significant Accounting Policies

Our significant accounting policies and others are presented in our Annual Report on Form 10-K for the year ended December 31, 2013, filed with the SEC on February 21, 2014. The policies include significant estimates made by management using information available at the time the estimates are made. However, these estimates could change materially if different information or assumptions were used.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers: Topic 606” (“ASU 2014-09”). ASU 2014-09 will enhance comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets, reduce the number of requirements which must be considered in recognizing revenue, improve disclosure to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized, and provide guidance for transactions that are not currently addressed comprehensively. The standard is effective for fiscal years beginning after December 15, 2016, and interim periods therein, and does not allow for early adoption. Entities have the option of using either a full retrospective or modified retrospective approach for the adoption of the standard. The Company has not yet begun the evaluation of the impact that the standard will have on its consolidated financial statements and has not yet selected a transition method.
