	1. Description of Business and Basis of Presentation
	Description of Business
	Nimble Storage, Inc. (the Company) was incorporated in the state of Delaware in November 2007. The Company’s mission is to provide its customers with the industry’s most efficient data storage platform. The Company has designed and sells a flash-optimized hybrid storage platform that it believes is disrupting the market by enabling significant improvements in application performance and storage capacity with superior data protection, while simplifying business operations and lowering costs. With the combination of the Company’s file system, CASL, and its cloud-based storage management and support service, InfoSight, the Company’s platform serves a broad array of enterprises and cloud-based service providers, and the Company’s software and storage systems effectively handle mainstream applications, including virtual desktops, databases, email, collaboration and analytics. The Company is headquartered in San Jose, California, with employees in several international locations, including the United Kingdom, Australia, Canada, and Germany.
	Basis of Presentation and Consolidation
	The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and include the consolidated accounts of the Company and its subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.

	2. Summary of Significant Accounting Policies
	There have been no material changes in the Company’s significant accounting policies for the three months ended April 30, 2014, as compared to the significant accounting policies described in its Annual Report on Form 10-K for the fiscal year ended January 31, 2014.
	Use of Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Such estimates include, but are not limited to, the determination of the best estimated selling prices of deliverables included in multiple-deliverable revenue arrangements; the allowance for doubtful accounts; provision for excess or obsolete inventory; the useful lives of property and equipment; the warranty reserve; and the fair value of the Company’s common stock and stock options issued. Actual results could differ from these estimates.
	Concentrations
	The Company’s financial instruments that are exposed to concentrations of credit risk are primarily cash and cash equivalents and trade accounts receivable. Cash and cash equivalents are maintained primarily at one financial institution, and deposits may exceed the amount of insurance provided on such deposits. Risks associated with cash and cash equivalents are mitigated by banking with a creditworthy institution. The Company has not experienced any losses on its deposits of cash and cash equivalents.
	The Company performs ongoing credit evaluations of its customers’ financial condition whenever deemed necessary and generally does not require collateral. The Company maintains an allowance for doubtful accounts based upon the expected collectability of its accounts receivable, which takes into consideration specific customer creditworthiness and current economic trends. During the third and fourth quarters of the year ended January 31, 2014, the Company consolidated the majority of its North American sales to two distributors, and as a result, accounts receivable and revenue increased in concentration. The majority of previous value added resellers (VARs) are now purchasing from these two distributors. Of all the Company’s customers, which include direct end-customers, VARs and distributors, the following customers individually accounted for more than 10% of the Company’s accounts receivable and revenue at the end of and for each period presented:
			% of Accounts Receivable									% of Revenue
			As of									Three Months Ended April 30,
			April 30, 2014					January 31, 2014				2014			2013
	Customer A				52	%				47	%		55	%		*
	Customer B				20	%				21	%		22	%		*
	Customer C				*					*			*			12	%
	Customer D				*					10	%		*			*
	*	Represents less than 10%.
	There are no concentrations of business transacted with a particular market that would severely impact the Company’s business in the near term. However, the Company currently relies on a few key contract manufacturer and suppliers to produce most of its products; any disruption or termination of these arrangements could materially adversely affect the Company’s operating results.
	Warranties
	The Company provides a standard one-year warranty for hardware components covering material defects in materials and workmanship. In addition, the Company provides a 90-day warranty on the embedded software in its products for non-conformance with documented specifications. The Company accrues for estimated warranty costs based upon historical experience, and periodically assesses the adequacy of its recorded warranty liability at the end of each period. These costs are expensed as incurred and included in cost of product revenue in the Company’s consolidated statements of operations. The Company records warranty liability in other current liabilities in its consolidated balance sheet.
	The table below summarizes the activity in the warranty accrual (in thousands):
			Three Months Ended April 30,
			2014				2013
	Beginning balance		$	537			$	275
	Warranty expense for new warranties issued			181				305
	Utilization of warranty obligation			(216	)			(194	)
	Ending balance		$	502			$	386
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (FASB) released Accounting Standards Update (ASU) No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The new standard requires that an unrecognized tax benefit should be presented as a reduction of a deferred tax asset for a net operating loss carryforward or other tax credit carryforward when settlement in this manner is available under the tax law. The Company adopted this accounting standard update on February 1, 2014 and the adoption did not have a significant impact on its consolidated financial position, results of operations, comprehensive loss or cash flows.

	4. Fair Value Measurements
	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, to measure the fair value:
		•	Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
		•	Level 2—Inputs are quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments.
		•	Level 3—Inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation.
	As of April 30, 2014 and 2013, the Company has no financial instruments other than cash and cash equivalents.

Certain costs incurred in the application development stage of a new product or projects are capitalized if certain criteria are met. Such costs are depreciated on a straight-line basis over the estimated useful lives of the related assets, which was estimated to be three years. Maintenance and training costs are typically expensed as incurred.
	Depreciation expense related to property and equipment for the three months ended April 30, 2014 and 2013 was $1.8 million and $0.6 million, respectively.

	Leases
	The Company leases its facilities under various noncancelable operating leases with fixed rental payments. Rent expense totaled $1.2 million and $0.3 million for the three months ended April 30, 2014 and 2013, respectively.
	Future minimum commitments under these operating leases as of April 30, 2014 were as follows (in thousands):
	Years ending January 31:
	2015 (remaining nine months)	$	4,087
	2016		4,743

	2018		4,743
	2019		4,861
	Thereafter		13,989
		$	37,152
	In April 2013, the Company entered into a new facility lease agreement for its corporate headquarters. The 96-month lease commenced on November 1, 2013 and provides 164,608 square feet space in San Jose, California. Total rent, including operating expenses, payable over the lease period is $35.5 million. As part of the lease agreement, the Company received $4.9 million in tenant improvement allowance during the year ended January 31, 2014. This tenant improvement allowance was included in the calculation of rent expense and related deferred rent balances. As a condition of the lease agreement, the Company is required to maintain a letter of credit of $3.9 million, with the landlord named as the beneficiary. The Company has the option to extend the term of the lease for an additional period of 60 months.
	Contingencies
	From time to time, the Company is party to litigation and subject to claims that arise in the ordinary course of business, including actions with respect to employment claims and other matters. Although the results of litigation and claims are inherently unpredictable, the Company believes that the final outcome of such matters will not have a material adverse effect on the business, consolidated financial position, results of operations or cash flows.
	On October 29, 2013, NetApp, Inc. (NetApp) filed a lawsuit in United States District Court, Northern District of California, alleging violations of the federal Computer Fraud and Abuse Act, trade secret misappropriation, unfair competition and related state law claims. The Company and three individuals, a sales engineer employee of an Australian affiliate, along with a sales representative and program manager of the Company, have been named as defendants. On January 10, 2014, NetApp filed a First Amended Complaint that added similar state law claims against three additional individuals as defendants. The First Amended Complaint alleges that the Australian defendant, a former employee of a NetApp reseller, accessed NetApp’s password-protected website allegedly restricted to NetApp partners, resellers, employees and customers, and downloaded confidential and proprietary information in violation of the Computer Fraud and Abuse Act. It further alleges that the other five individual defendants, who were formerly employed at NetApp, downloaded NetApp company documents and materials, including allegedly confidential and trade secret information and/or deleted NetApp documents and materials, prior to leaving NetApp. The complaint seeks unspecified damages and injunctive relief. Because the Company is in the early stages of litigation, it is unable to estimate a range of possible losses, if any. The Company filed a response to the complaint on February 18, 2014. On May 12, 2014, the Court dismissed Nimble and all of the individual defendants except for the Australian defendant from the lawsuit. The court allowed NetApp to file an amended complaint concerning some of its claims, and NetApp filed a Second Amended Complaint on June 2, 2014. The Second Amended Complaint contains claims of alleged violations of the Computer Fraud and Abuse Act, unfair competition and related state law claims against the Company and the employee of an Australian affiliate of the Company. Litigation is inherently uncertain and can involve significant management time and attention. In addition, the cost of any litigation, regardless of outcome, can be significant and there can be no assurance that resolution of this matter will not have a material adverse effect on the Company’s operating results. The Company intends to vigorously defend itself in this litigation.
	On May 16, 2014, NetApp filed a lawsuit in the Superior Court of California, County of Santa Clara against the Company and the five individuals who were dismissed from the federal lawsuit, alleging claims that were similar to those dismissed from the federal lawsuit (i.e., that the individual defendants downloaded NetApp company documents and materials, including allegedly confidential and trade secret information and/or deleted NetApp documents and materials, prior to leaving NetApp). The state court complaint seeks unspecified damages and injunctive relief. Because the Company is in the early stages of litigation, it is unable to estimate a range of possible losses, if any. Litigation is inherently uncertain and can involve significant management time and attention. In addition, the cost of any litigation, regardless of outcome, can be significant and there can be no assurance that resolution of this matter will not have a material adverse effect on the Company’s operating results. As with the federal lawsuit, the Company intends to vigorously defend itself in this litigation.
	On March 11, 2011, Nimbus Data Systems, Inc. filed a lawsuit in the United States District Court for the Northern District of California against the Company, alleging that the Company’s use of Nimble Storage as its trade name and trademark constitutes trademark infringement, unfair competition and false and misleading advertising. On April 23, 2012, the Company entered into a confidential settlement agreement related to this matter, resolving all claims brought against the Company without admission of fault or liability by either party. As of January 31, 2012, the Company accrued the settlement amount in other current liabilities within its consolidated balance sheet and recognized the related expense in general and administrative expense in the Company’s consolidated statement of operations. The settlement amount was paid on April 23, 2012.
	Indemnification
	Some of the Company’s sales contracts require the Company to indemnify its customers against third-party claims asserting infringement of certain intellectual property rights, which may include patents, copyrights, trademarks, or trade secrets, and to pay judgments entered on such claims. The Company’s exposure under these indemnification provisions is generally limited to the total amount paid by the customer under the contract. However, certain contracts include indemnification provisions that could potentially expose the Company to losses in excess of the amount received under the contract. In addition, the Company indemnifies its officers, directors, and certain key employees while they are serving in good faith in their respective capacities. To date, there have been no claims under any indemnification provisions.

Line of Credit	'
	10. Line of Credit
	In October 2013, the Company entered into an agreement with Wells Fargo Bank, National Association (Wells Fargo) to provide a secured revolving credit facility (the Credit Facility) that allows the Company to borrow up to $15.0 million for general corporate purposes. Amounts outstanding under the Credit Facility will bear interest at Wells Fargo’s prime rate with accrued interest payable on a monthly basis. In addition, the Company is obligated to pay a commitment fee of 0.20% per annum on the unused portion of the Credit Facility, with such fee payable on a quarterly basis. As of April 30, 2014, the commitment fee was capitalized and being amortized on the Company’s consolidated balance sheet. The Credit Facility expires in October 2014. As part of the credit facility, the Company granted to Wells Fargo a first priority lien in its accounts receivable and other corporate assets, agreed to not pledge its intellectual property to other parties and became subject to certain reporting and financial covenants, as follows: (1) maintain specified quarterly levels of EBITDA, which is defined as net income before tax plus interest expense (net of capitalized interest expense), depreciation expense and non-cash stock compensation expense; and (2) maintain a monthly ratio of not less than 1.25 to 1.00, based on the aggregate of its cash and net accounts receivable divided by total current liabilities minus current deferred revenue. As of April 30, 2014, no amounts had been drawn against the Credit Facility.

Accounting Policies [Abstract]

'

Basis of Presentation and Consolidation

'

Basis of Presentation and Consolidation

The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and include the consolidated accounts of the Company and its subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

'

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Such estimates include, but are not limited to, the determination of the best estimated selling prices of deliverables included in multiple-deliverable revenue arrangements; the allowance for doubtful accounts; provision for excess or obsolete inventory; the useful lives of property and equipment; the warranty reserve; and the fair value of the Company’s common stock and stock options issued. Actual results could differ from these estimates.

Concentrations

'

Concentrations

The Company’s financial instruments that are exposed to concentrations of credit risk are primarily cash and cash equivalents and trade accounts receivable. Cash and cash equivalents are maintained primarily at one financial institution, and deposits may exceed the amount of insurance provided on such deposits. Risks associated with cash and cash equivalents are mitigated by banking with a creditworthy institution. The Company has not experienced any losses on its deposits of cash and cash equivalents.

The Company performs ongoing credit evaluations of its customers’ financial condition whenever deemed necessary and generally does not require collateral. The Company maintains an allowance for doubtful accounts based upon the expected collectability of its accounts receivable, which takes into consideration specific customer creditworthiness and current economic trends. During the third and fourth quarters of the year ended January 31, 2014, the Company consolidated the majority of its North American sales to two distributors, and as a result, accounts receivable and revenue increased in concentration. The majority of previous value added resellers (VARs) are now purchasing from these two distributors. Of all the Company’s customers, which include direct end-customers, VARs and distributors, the following customers individually accounted for more than 10% of the Company’s accounts receivable and revenue at the end of and for each period presented:

There are no concentrations of business transacted with a particular market that would severely impact the Company’s business in the near term. However, the Company currently relies on a few key contract manufacturer and suppliers to produce most of its products; any disruption or termination of these arrangements could materially adversely affect the Company’s operating results.

Warranties

'

Warranties

The Company provides a standard one-year warranty for hardware components covering material defects in materials and workmanship. In addition, the Company provides a 90-day warranty on the embedded software in its products for non-conformance with documented specifications. The Company accrues for estimated warranty costs based upon historical experience, and periodically assesses the adequacy of its recorded warranty liability at the end of each period. These costs are expensed as incurred and included in cost of product revenue in the Company’s consolidated statements of operations. The Company records warranty liability in other current liabilities in its consolidated balance sheet.

Recent Accounting Pronouncements

'

Recent Accounting Pronouncements

In July 2013, the Financial Accounting Standards Board (FASB) released Accounting Standards Update (ASU) No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The new standard requires that an unrecognized tax benefit should be presented as a reduction of a deferred tax asset for a net operating loss carryforward or other tax credit carryforward when settlement in this manner is available under the tax law. The Company adopted this accounting standard update on February 1, 2014 and the adoption did not have a significant impact on its consolidated financial position, results of operations, comprehensive loss or cash flows.

Fair Value Measurements

'

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, to measure the fair value:

•

Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

•

Level 2—Inputs are quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments.

•

Level 3—Inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation.

Inventory

'

Inventory

Inventories consist primarily of raw materials related to component parts, finished goods, which include both inventory held for sale and service inventory held at service depots in support of customer service agreements, and customer evaluation inventory.

Research, Development, and Computer Software

'

Costs incurred in connection with the development of the Company’s software are accounted for as follows: all costs incurred in the preliminary project and post-implementation stages are expensed as incurred. Certain costs incurred in the application development stage of a new product or projects are capitalized if certain criteria are met. Such costs are depreciated on a straight-line basis over the estimated useful lives of the related assets, which was estimated to be three years. Maintenance and training costs are typically expensed as incurred.

Commitments and Contingencies

'

From time to time, the Company is party to litigation and subject to claims that arise in the ordinary course of business, including actions with respect to employment claims and other matters. Although the results of litigation and claims are inherently unpredictable, the Company believes that the final outcome of such matters will not have a material adverse effect on the business, consolidated financial position, results of operations or cash flows.

Segment Reporting

'

The Company’s chief operating decision maker is its chief executive officer. The chief executive officer reviews consolidated financial information accompanied by information about revenue by product line for purposes of allocating resources and evaluating financial performance. The Company has one business activity and there are no segment managers who are held accountable for operations, or operating results for levels or components. In addition, the majority of the Company’s operations and customers are located in the United States. As such, the Company has a single reporting segment and operating unit structure.
