Description of the Business and Summary of Significant Accounting Policies | ' |
DESCRIPTION OF THE BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | |
Business | |
Infoblox Inc. (together with its subsidiaries, “we” or “our”) was originally incorporated in the State of Illinois in February 1999 and was reincorporated in the State of Delaware in May 2003. We are headquartered in Santa Clara, California and have subsidiaries and representative offices located throughout the world. We provide a broad family of enterprise and service provider-class solutions to automate management of the critical network infrastructure services needed for secure, scalable and fault-tolerant connections between applications, devices and users. | |
Initial Public Offering | |
On April 25, 2012, we completed our initial public offering of our common stock (“IPO”). Our common stock commenced trading on the New York Stock Exchange under the symbol “BLOX” on April 20, 2012. On the IPO, we sold 6.9 million shares of common stock (inclusive of 1.1 million shares of common stock from the full exercise of the overallotment option of shares granted to the underwriters) and 1.8 million shares of common stock were sold by the selling stockholders. The public offering price of the shares sold in the offering was $16.00 per share. The aggregate offering price for shares sold by us in the offering was approximately $109.9 million. We did not receive any proceeds from the sales of shares by the selling stockholders. The net proceeds from the offering were $98.2 million after deducting underwriting discounts and commissions of approximately $7.7 million and offering expenses of approximately $4.0 million. Concurrent with the closing of the IPO, all shares of our convertible preferred stock automatically converted into 26.8 million shares of common stock and all shares of convertible preferred stock warrants converted to common stock warrants, of which an insignificant amount remained unexercised as of July 31, 2014. | |
Secondary Offering | |
On October 11, 2012, we closed a secondary offering, in which certain of our stockholders offered 5.0 million shares of common stock at a price to the public of $20.00 per share. The aggregate offering price for shares sold in the offering was $96.0 million, net of underwriting discounts and commissions. The underwriters did not exercise their option to purchase 0.8 million additional shares of common stock from our selling stockholders. We did not receive any proceeds from the sale of shares in this offering. In connection with this offering, we incurred approximately $0.8 million expenses, which were included in general and administrative expenses in the consolidated statement of operations for the year ended July 31, 2013. | |
Basis of Presentation | |
The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include all adjustments necessary for the fair presentation of our consolidated financial position, results of operations and cash flows for the periods presented. The accompanying consolidated financial statements include the accounts of Infoblox Inc. and our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. | |
Use of Estimates | |
The preparation of the accompanying consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Those management estimates and assumptions affect revenue recognition, determination of fair value of stock-based awards, valuation of goodwill and intangible assets acquired, impairment of goodwill and other intangible assets, amortization of intangible assets, contingencies and litigation, accounting for income taxes, including the valuation reserve on deferred tax assets and uncertain tax positions, allowances for doubtful accounts, warranty reserve and sales returns and valuation of inventory. We evaluate our estimates and assumptions on an ongoing basis using historical experience and other factors and adjust those estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ from these estimates and assumptions, and those differences could be material to the consolidated financial statements. | |
Concentration of Supply Risk with Contract Manufacturer | |
We outsource the substantial majority of our manufacturing, repair and supply chain management operations to one independent contract manufacturer. The inability of the manufacturer to fulfill our supply requirements could have a material and adverse effect on our business and consolidated financial statements. | |
In addition, our independent contract manufacturer procures components and manufactures our products based on our demand forecasts. These forecasts are based on our estimates of future demand for our products, which are in turn based on historical trends and an analysis from our sales and marketing organizations, adjusted for overall market conditions. We may be subject to the requirement to purchase inventory or to pay additional fees to the contract manufacturer if there is a significant difference in scheduled shipments or if the contract manufacturer holds inventory longer than a specified period. In 2012, we recorded a charge of $0.4 million for non-cancelable purchase commitments to our contract manufacturer for inventory which we deemed as excess and obsolete. This amount was recognized in products and licenses cost of revenue in the consolidated statement of operations for the year ended July 31, 2012. No significant charge was recorded in 2014 or 2013. | |
Concentrations of Credit Risk | |
Financial instruments that potentially subject us to concentrations of credit risk consist of cash, cash equivalents, restricted cash and accounts receivable. Our cash, cash equivalents and restricted cash are invested in high-credit quality financial instruments held mainly in two US banks. Such deposits may be in excess of insured limits provided on such deposits. | |
We mitigate credit risk in respect to accounts receivable by performing ongoing credit evaluations of our customers and maintaining a reserve for potential credit losses. In addition, we generally require our customers to prepay for maintenance and support services to mitigate the risk of uncollectible accounts receivable. | |
Reverse Stock Split | |
On April 3, 2012, our board of directors approved a 1-for-3 reverse split of our common stock, which became effective on April 10, 2012. Upon the effectiveness of the reverse stock split, (i) every three shares of outstanding common stock were decreased to one share of common stock, (ii) the number of shares of common stock into which each outstanding option to purchase common stock is exercisable have been proportionally decreased on a 1-for-3 basis, (iii) the exercise price of each outstanding option to purchase common stock have been proportionately increased, and (iv) the conversion ratio for each share of preferred stock outstanding have been proportionately reduced. All of the share numbers, share prices, and exercise prices have been adjusted within these financial statements, on a retroactive basis, to reflect this 1-for-3 reverse stock split. | |
Cash and Cash Equivalents | |
All highly liquid investments purchased with an original maturity of three months or less are classified as cash and cash equivalents. Cash and cash equivalents consist of cash on hand, demand deposits with banks, highly liquid investments in money market funds, U.S. Treasury securities and certificates of deposit which are readily convertible into cash. | |
Restricted Cash | |
Under our facility lease arrangements, we are required to maintain letters of credit from a U.S. bank as security for performance under these agreements. The letters of credit are generally invested in U.S. Treasury securities or money market funds or interest-bearing accounts in amounts equal to the letters of credit, which are classified as restricted cash on the consolidated balance sheets. Restricted cash, which is shown under non-current assets in the consolidated balance sheets, amounted to $3.5 million as of July 31, 2014 and 2013. | |
Short-term Investments | |
Investments with original maturities at purchase of greater than three months are classified as short-term or long-term investments. Management determines the appropriate classification of securities at the time of purchase and re-evaluates such classification as of each balance sheet date. | |
Our investments in publicly-traded debt securities are classified as available-for-sale. Available-for-sale investments are initially recorded at cost and periodically adjusted to fair value in the consolidated balance sheets. Unrealized gains and losses on these investments are reported as a separate component of accumulated other comprehensive income (loss). Realized gains and losses are determined based on the specific identification method and are reported in the consolidated statements of operations. The investments are adjusted for amortization of premiums and discounts to maturity and such amortization is included in other expense, net. | |
We recognize an impairment charge for available-for-sale investments when a decline in the fair value of our investments below the cost basis is determined to be other than temporary. We consider various factors in determining whether to recognize an impairment charge, including the length of time the investment has been in a loss position, the extent to which the fair value has been less than the cost basis, the investment's financial condition and near-term prospects, and our intent to sell, or whether it is more likely than not we will be required to sell, the investment before recovery of the investment's amortized cost basis. If we determine that the decline in an investment's fair value is other than temporary, the difference is recognized as an impairment loss in our consolidated statements of operations. During the year ended July 31, 2014, we did not consider any of our investments to be other-than-temporarily impaired. | |
Fair Value | |
Fair value is defined as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value, we consider the principal or most advantageous market in which we transact, and consider assumptions that market participants would use when pricing the asset or liability. We apply the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: | |
Level I - Quoted prices in active markets for identical assets or liabilities. | |
Level II - Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. These inputs are valued using market based approaches. | |
Level III - Inputs are unobservable inputs based on management assumptions. These inputs, if any, are valued using internal financial models. | |
Inventory | |
Inventories are stated at the lower of standard cost, which approximates actual cost (first-in, first-out), or market value (estimated net realizable value). The valuation of inventories at the lower of cost or market value requires the use of estimates regarding the amount of inventory that will be sold and the prices at which current inventory will be sold. These estimates are dependent on our assessment of current and expected orders from our customers. If actual market conditions are less favorable than those projected by management, inventory write-downs may be required. Our finished goods mainly consist of appliances that are used for the replacement of failed units under maintenance and support agreements and finished goods needed for our expanded depot requirements. We write down refurbished inventory based on the age of the units and number of hardware failures. During the years ended July 31, 2014, 2013 and 2012, inventory write-downs were $1.3 million, $1.1 million and $0.6 million. | |
Property and Equipment, Net | |
Property and equipment, including leasehold improvements, are stated at cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets, which are two to three years. Leasehold improvements are amortized on a straight-line basis over the shorter of the estimated useful lives of the assets or the remaining lease term. Upon the retirement or disposition of property and equipment, the related costs and accumulated depreciation are removed from, and the resulting gain or loss is included in, the consolidated statements of operations. Repair and maintenance costs that do not extend the life or improve an asset are charged to expense as incurred. | |
Goodwill, Intangible Assets and Other Long-Lived Assets | |
Goodwill represents the future economic benefits arising from other assets acquired in a business combination or an acquisition that are not individually identified and separately recorded. The excess of the purchase price over the estimated fair value of net assets of businesses acquired in a business combination is recognized as goodwill. | |
Intangible assets consist of identifiable intangible assets, including developed technology, customer relationships, non-compete agreements, trademarks and patents, resulting from our acquisitions. Intangible assets are recorded at fair value, net of accumulated amortization. Intangible assets are amortized on a straight-line basis over their estimated useful lives. Amortization expense is included as a component of cost of products and licenses revenue and sales and marketing expense in the accompanying consolidated statements of operations. Amounts included in sales and marketing expense relate to amortization of intangible asset attributed to customer relationships. | |
Goodwill and other intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually during the fourth quarter. Such goodwill and other intangible assets may also be tested for impairment between annual tests in the presence of impairment indicators such as, but not limited to: (a) a significant adverse change in legal factors or in the business climate; (b) a substantial decline in our market capitalization, (c) an adverse action or assessment by a regulator; (d) unanticipated competition; (e) loss of key personnel; (f) a more likely-than-not expectation of sale or disposal of a reporting unit or a significant portion thereof; (g) a realignment of our resources or restructuring of our existing businesses in response to changes to industry and market conditions; (h) testing for recoverability of a significant asset group within a reporting unit; or (i) higher discount rate used in the impairment analysis as impacted by an increase in interest rates. | |
We evaluate goodwill on an annual basis as of May 1st or more frequently if we believe impairment indicators exist. Goodwill is tested for impairment by comparing the reporting unit's carrying value, including goodwill, to the fair value of the reporting unit. We operate under one reporting unit and for our annual goodwill impairment analysis, we determine the fair value of our reporting unit based on the Company's enterprise value. | |
Long-lived assets, such as property and equipment and intangible assets subject to depreciation and amortization, are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Among the factors and circumstances we considered in determining recoverability are: (i) a significant decrease in the market price of a long-lived asset; (ii) a significant adverse change in the extent or manner in which a long-lived asset is being used or in its physical condition; (iii) a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset, including an adverse action or assessment by a regulator; (iv) an accumulation of costs significantly in excess of the amount originally expected for the acquisition and (v) current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. | |
There have been no indicators of impairment of goodwill, intangible assets and other long-lived assets, and we did not record any impairment losses during the years ended July 31, 2014, 2013 and 2012. | |
Revenue Recognition | |
We generate revenue from the sales or licensing of hardware and software products, support and maintenance, and other services through a direct sales force and indirect relationships with our partners. Revenue is recognized when all of the following criteria are met: | |
Persuasive evidence of an arrangement exists. Evidence of an arrangement generally consists of a purchase order issued pursuant to the terms and conditions of a distributor or value-added reseller agreement or, in limited cases, an end-user agreement. | |
Delivery or performance has occurred. We use shipping and related documents, distributor sell-through reports, or written evidence of customer acceptance, when applicable, to verify delivery or performance. We do not recognize product revenue until transfer of title and risk of loss, which generally is upon shipment to value-added resellers or end-users. | |
The sales price is fixed or determinable. We assess whether the sales price is fixed or determinable based on payment terms and whether the sales price is subject to refund or adjustment. | |
Collection is probable. We assess probability of collection on a customer-by-customer basis. We subject our customers to a credit review process that evaluates their financial condition and ability to pay for our products and services. If we conclude that collection is not probable, we do not recognize revenue until cash is received. | |
We recognize product revenue at the time of shipment provided that all other revenue recognition criteria have been met. Services revenue includes maintenance and support, training and consulting, and subscription services revenue. Maintenance and support revenue includes arrangements for software maintenance and technical support for our products and licenses. Maintenance is offered under renewable, fee-based contracts, which include 24-hour technical support, hardware repair and replacement parts, bug fixes, patches and unspecified upgrades on a when-and-if-available basis. Revenue from customer maintenance and support contracts and subscription services is deferred and recognized ratably over the contractual period, generally one to three years. Revenue from consulting and training is recognized as the services are completed. | |
We operate a multiple tier channel distribution model that includes distributors, value-added resellers and direct sales to end-users. For sales to value-added resellers and end-users, we recognize product revenue upon transfer of title and risk of loss, which is generally upon shipment. It is our practice to identify an end-user prior to shipment to a value-added reseller. For the end-users and value-added resellers, we generally have no significant contractual obligations for future performance, such as rights of return or pricing credits. However, we may on occasion enter into arrangements with end-users or value-added resellers that include some form of rights of return, rebates or price protection. Also, we may occasionally accept returns by end-users or value-added resellers to address customer satisfaction issues or solution fit issues even though there is no contractual provision for such returns. We record reductions to revenue for estimated product returns and pricing adjustments in the same period that the related revenue is recorded. The amount of these reductions is based on historical sales returns and price adjustments, specific provisions for returns, price protection or rebates in agreements, and other factors known at the time. Should actual product returns or pricing adjustments differ from estimates, additional reductions to revenue may be required. Distributor revenue is subject to agreements that may allow pricing credits, price protection, rebates and rights of return or involve international jurisdictions where the risk of returns or credits is considered to be high even though distributors do not have these contractual rights. As a consequence, the Company has determined that the sales price is not fixed or determinable at the time of shipment to a distributor and thus revenue and related costs of sales for these shipments are deferred until information is received from the distributor indicating that the product has been sold through to an end customer or value added reseller. | |
Multiple Element Arrangements | |
We enter into multiple element revenue arrangements in which a customer may purchase a combination of hardware, software, software upgrades, hardware and software maintenance and support, training and consulting, and subscription services. We account for multiple agreements with a single customer as one arrangement if the contractual terms and/or substance of those agreements indicate that they may be so closely related that they are, in effect, parts of a single arrangement. | |
Most of our products are hardware appliances containing software components that operate together to provide the essential functionality of the product. Therefore, the software sold with our hardware appliances are considered non-software deliverables and are not accounted for under the industry-specific software revenue recognition guidance. | |
Our products and licenses revenue also includes stand-alone software products. Stand-alone software may operate on our hardware appliances, but is not considered essential to the functionality of the hardware and continues to be subject to the industry-specific software revenue recognition guidance. The industry-specific software revenue recognition guidance includes the use of the residual method under which the amount of revenue allocated to delivered elements equals the total arrangement consideration less the aggregate fair value of any undelivered elements. If VSOE of fair value of one or more undelivered items does not exist, revenue from the entire arrangement is deferred and recognized at the earlier of: (i) delivery of those elements or (ii) when fair value can be established unless support and maintenance is the only undelivered element, in which case, the entire arrangement fee is recognized ratably over the contractual service period. | |
We provide unspecified software upgrades for most of our products, on a when-and-if available basis, through maintenance and support contracts. To the extent that the software being supported does not function together with the hardware to deliver the hardware’s essential functionality, these support arrangements would continue to be subject to the industry-specific software revenue recognition guidance. | |
We allocate the arrangement fee to each element based upon the relative selling price of that element and, if software and software-related (e.g., maintenance for the software element) elements are also included in the arrangement, we allocate the arrangement fee to each of those software and software-related elements as a group based on the relative selling price for those elements. After such allocations are made, the amount of the arrangement fee allocated to the software and software-related elements is accounted for using the residual method. When applying the relative selling price method, we determine the selling price for each element using vendor-specific objective evidence, or VSOE, of selling price, if it exists, or if not, third-party evidence, or TPE, of selling price, if it exists. If neither VSOE nor TPE of selling price exist for an element, we use our best estimate of selling price, or BESP, for that element. The revenue allocated to each element is then recognized when the basic revenue recognition criteria are met for that element. We limit the amount of revenue recognized for delivered elements to an amount that is not contingent upon future delivery of additional products or services or meeting of any specified performance conditions. | |
Whenever possible, we determine VSOE for each element based on historical stand-alone sales to third parties. For maintenance and support, training and consulting, and subscription services, we determine the VSOE of fair value based on our history of stand-alone sales demonstrating that a substantial majority of transactions fall within a narrow range for each service offering. | |
We historically have not been able to determine TPE for our products, maintenance and support, training or consulting services. TPE is determined based on competitor prices for similar elements when sold separately. Generally, our offerings contain a significant level of differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, our go-to-market strategy differs from that of our peers and we are unable to reliably determine what similar competitor products' selling prices are on a stand-alone basis. | |
When we are unable to establish the selling price of an element using VSOE or TPE, we use BESP in our allocation of consideration to various elements under the arrangement. The objective of BESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. The BESP is established based on internal and external factors, including pricing practices such as discounting, cost of products, the geographies in which we offer our products and services, and customer classes and distribution channels (e.g. distributor, value-added reseller and direct end-user). The determination of BESP is made through consultation with and approval by our management, taking into consideration our pricing model and go-to-market strategy. | |
For our non-software deliverables, we generally determine relative selling price based on BESP. However, for our maintenance and support, training and consulting, and subscription services, we generally use VSOE to determine relative selling price. When we are unable to establish selling price using VSOE for our maintenance and support, training and consulting, and subscription services, we use BESP in our allocation of arrangement consideration. | |
We regularly review VSOE and BESP data provided by actual transactions to update these estimates and the relative selling prices allocated to each element. | |
Deferred Revenue, Net | |
Deferred revenue, net represents amounts invoiced to customers, less related cost of revenue, for which the related revenue has not been recognized because one or more of the revenue recognition criteria have not been met. The current portion of deferred revenue represents the amounts that are expected to be recognized as revenue within one year of the consolidated balance sheet date. | |
Accounts Receivable and Allowance for Doubtful Accounts | |
Accounts receivable are recorded at invoiced amounts, net of allowances for doubtful accounts if applicable, and do not bear interest. | |
We evaluate the collectability of our accounts receivable based on known collection risks and historical experience. In circumstances where we are aware of a specific customer's inability to meet its financial obligations to us (e.g., bankruptcy filings or substantial downgrading of credit ratings), we record a specific reserve for bad debts against amounts due to reduce the net recognized receivable to the amount we reasonably believe will be collected. For all other customers, we record reserves for bad debts based on the length of time the receivables are past due and our historical experience of collections and write-offs. If circumstances change, such as higher-than-expected defaults or an unexpected material adverse change in a major customer's ability to meet its financial obligations, our estimate of the recoverability of the amounts due could be reduced by a material amount. | |
Concentration of Revenue and Accounts Receivable | |
Significant customers are those which represent more than 10% of our total net revenue or gross accounts receivable balance at each respective balance sheet date. Exclusive Networks, a distributor, accounted for 10.5% and 11.5% of our total net revenue for the years ended July 31, 2014 and 2013. No single end customer, distributor or channel partner accounted for more than 10% of our net revenue in 2012. As of July 31, 2014 and 2013, Exclusive Networks accounted 12.8% and11.2% of our total gross accounts receivable. | |
Shipping and Handling | |
Shipping charges billed to customers are included in revenue and the related shipping costs are included in cost of revenue. | |
Research and Development Costs | |
Software development costs incurred in the research and development of new products and enhancements to existing products are charged to expense as incurred. Software development costs are capitalized after technological feasibility has been established. The period between achievement of technological feasibility, which we define as the establishment of a working model, and the general availability of such software to customers has been short, resulting in software development costs qualifying for capitalization being insignificant. Accordingly, we did not capitalize any software development costs during the years ended July 31, 2014, 2013 and 2012. | |
Stock-Based Compensation | |
We recognize share-based compensation expense for all share-based payment awards including employee stock options, RSUs, and purchases under our ESPP based on each award's fair value on the grant date. We utilize the BSM option pricing model in order to determine the fair value of stock options and ESPP. The BSM option pricing model requires various highly subjective assumptions including volatility, expected award life, and risk-free interest rate. Since we only have a short trading history of our common stock (approximately 30 months since our IPO), we use a blended volatility to estimate expected volatility. The blended volatility includes a weighting of our historical volatility from the date of our IPO to the respective grant date and the average historical stock volatilities of several unrelated public companies within our industry that we consider to be comparable to our business over a period equivalent to the estimated life of our stock options. The expected life of an award is based on historical experience, the terms and conditions of the stock awards granted to employees, and the potential effect from options that have not been exercised. The fair value of the RSUs is determined using the closing price of our common stock on the date of the grant. Compensation is recognized on a straight-line basis over the requisite service period of each grant adjusted for estimated forfeitures. In addition, we are required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. We estimate the forfeiture rate based on historical experience and our expectations regarding future pre-vesting termination behavior of employees. | |
Warranty Costs | |
Our appliance hardware generally includes a one-year warranty, and our software generally carries a warranty of ninety days. Costs related to hardware replacement provided to customers under maintenance support agreements are included as services cost of revenue and recognized as these services are provided. | |
Advertising Costs | |
Advertising costs are charged to sales and marketing expenses as incurred in the consolidated statements of operations. Advertising expense during the years ended July 31, 2014, 2013 and 2012 was $1.3 million, $1.0 million and $1.1 million. | |
Foreign Currency | |
The functional currency of our foreign subsidiaries is the U.S. dollar. Transactions denominated in currencies other than the functional currency are remeasured at the average exchange rate in effect during the period. At the end of each reporting period, our subsidiaries' monetary assets and liabilities are remeasured to the functional currency using exchange rates in effect at the end of the reporting period. Non-monetary assets and liabilities are remeasured at historical exchange rates. Gains and losses related to remeasurement are recorded in other expense, net in the consolidated statements of operations. Foreign currency exchange losses included in other expense, net during the years ended July 31, 2014, 2013 and 2012 were $0.5 million, $0.8 million and $0.6 million. | |
Income Taxes | |
We account for income taxes under an asset and liability approach for deferred income taxes, which requires recognition of deferred income tax assets and liabilities for the expected future tax consequences of events that have been recognized in our consolidated financial statements, but have not been reflected in our taxable income. Estimates and judgments occur in the calculation of certain tax liabilities and in the determination of the recoverability of certain deferred income tax assets, which arise from temporary differences and carryforwards. Deferred income tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. We regularly assess the likelihood that our deferred income tax assets will be realized based on the realization guidance available. To the extent that we believe any amounts are not more-likely-than-not to be realized, we record a valuation allowance to reduce the deferred income tax assets. We regularly assess the need for the valuation allowance on our deferred tax assets, and to the extent that we determine that an adjustment is needed, such adjustment will be recorded in the period that the determination is made. | |
We regularly review our tax positions and benefits to be realized. We recognize tax liabilities based upon our estimate of whether, and the extent to which, additional taxes will be due when such estimates are more-likely-than-not to be sustained. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. We recognize interest and penalties related to income tax matters as income tax expense. For the years ended July 31, 2014, 2013 and 2012, we did not incur any interest or penalties associated with unrecognized tax benefits. | |
Segment Information | |
Operating segments are components of an enterprise for which separate financial information is available and is evaluated regularly by our chief operating decision maker in deciding how to allocate resources and assessing performance. Our chief operating decision maker is our Chief Executive Officer. | |
Our Chief Executive Officer reviews financial information presented on a consolidated basis, for purposes of allocating resources and evaluating financial performance. We have one business activity and there are no segment managers who are held accountable for operations, operating results beyond revenue goals or gross margins, or plans for levels or components below the consolidated unit level. Accordingly, we have a single reporting segment. | |
Recently Issued Accounting Pronouncements | |
In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11, Income Taxes (Topic 740), Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). ASU 2013-11 provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, similar tax loss, or tax credit carryforward exists. This new standard requires the netting of unrecognized tax benefits (“UTBs”) against a deferred tax asset for a loss or other carryforward that would apply in settlement of the uncertain tax positions. UTBs will be netted against all available same-jurisdiction loss or other tax carryforwards that would be utilized, rather than only against carryforwards that are created by the UTBs. We adopted ASU 2013-11 during the first quarter of fiscal 2014 and the adoption did not have any impact on our consolidated financial position or results of operations. | |
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. The standard is effective for us beginning the first quarter of fiscal 2018, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements and have not yet determined the method by which we will adopt the standard in fiscal 2018. |

NET INCOME (LOSS) PER SHARE | |||||||||
We compute basic net income (loss) per share using the weighted average number of common shares outstanding during the period. We compute diluted net income per share using the weighted average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares include shares issuable upon the exercise of stock options or warrants, upon the conversion of convertible preferred stock and upon the vesting of restricted stock units, or RSUs, under the treasury stock method. | |||||||||
In loss periods, basic net loss per share and diluted net loss per share are the same since the effect of potential common shares is anti-dilutive and therefore excluded. | |||||||||
The following weighted-average shares of common stock equivalents were excluded from the computation of diluted net loss per share for the years presented because including them would have been antidilutive: | |||||||||

Prior to our IPO, holders of convertible preferred stock were entitled to receive noncumulative dividends at the annual rates per annum payable prior and in preference to any dividends on shares of our common stock. Preferred stockholders did not have a contractual obligation to share in the losses of our Company. Due to the net loss we reported in 2012, the convertible preferred stock did not have any impact in our net loss per share calculation in that year. |

Financial assets whose fair values we measure on a recurring basis using Level II inputs consist of U.S. government agency securities and Federal Deposit Insurance Corporation, or FDIC-backed certificates of deposit. We measure the fair values of these assets with the help of a pricing service that either provides quoted market prices in active markets for identical or similar securities or uses observable inputs for their pricing without applying significant adjustments because the inputs used in the valuation model, such as interest rates and volatility, can be corroborated by readily observable market data for substantially the full term of the financial assets. | |||||||||||||||||

ACQUISITIONS | |||||
On December 20, 2013, we closed the acquisition of substantially all of the assets of Internet Associates LLC, or IA, a small privately held software company that specialized in the automation of IP address management and IPv6. We did not acquire any tangible assets nor did we assume any material liabilities as part of this acquisition. We expect this acquisition will help us build on our core business. | |||||
We accounted for the IA acquisition using the acquisition method of accounting for business combinations. In addition to cash consideration of $1.0 million, we made employment offers to IA’s four former key employees in which they were granted an aggregate of 70,000 of our RSUs. Twenty-five percent of these RSUs, or 17,499, became fully vested upon closing of the transaction, and the remaining 52,501 RSUs will vest thereafter in four equal installments every six months over two years subject to their continued service to us. Aside from the RSU vesting conditions, there were no other incentives or contingent arrangements in connection with this acquisition. We accounted for the 17,499 RSUs as part of the purchase consideration as the vesting of such RSUs did not require any post-combination services. We have accounted for the other 52,501 RSUs as stock-based compensation since the vesting of such RSUs requires post-combination services. Based on the foregoing, the total purchase price of this acquisition consists of the following: | |||||
Amount in Thousands | |||||
Cash consideration | $ | 1,000 | |||
Fair value of fully vested RSUs (1) | 573 | ||||
Total consideration | $ | 1,573 | |||
-1 | This represents the fair value of the 17,499 RSUs that were granted to IA’s former key employees which became fully vested upon closing. We determined the fair value for purchase price consideration purposes based on our closing stock price of $32.73 on December 20, 2014, the effective closing of the transaction. | ||||
Of the total purchase price of $1.6 million, $1.0 million was allocated to the core/developed technology and $0.6 million was allocated to goodwill. The goodwill recognized in this transaction is deductible for tax purposes and is derived from expected benefits from cost synergies and former IA personnel who joined us after the acquisition. | |||||
We are amortizing the developed technology on a straight-line basis over an estimated useful life of 7 years. Amortization expense for this intangible asset was insignificant for the year ended July 31, 2014. | |||||
The acquisition-related transaction costs which were included in general and administrative expenses during the year ended July 31, 2014 in the consolidated statement of operations were insignificant. | |||||
The historical financial results of IA were insignificant in relation to our consolidated results of operations. As such, we did not provide additional historical pro forma acquisition information. |

We have entered into non-cancelable operating leases for facilities that expire at various dates through January 31, 2021. Rent under the agreements is expensed to operations on a straight-line basis over the terms of the leases. The aggregate future non-cancelable minimum lease payments for our operating leases as of July 31, 2014 consist of the following: | |||||

Rent expense for all operating leases amounted to $4.7 million, $4.6 million and $2.0 million during the years ended July 31, 2014, 2013 and 2012. | |||||
In May 2012, we entered into an agreement for the lease of an office building located in Santa Clara, California consisting of 127,000 square feet for an initial term of eight years which commenced in February 2013. This office building houses our corporate headquarters that we started occupying in March 2013. The annual base rent for this office lease ranges from approximately $3.2 million to $3.9 million over the term of the lease and we are also responsible for the payment of certain operating expenses, including utilities and real estate taxes. Pursuant to the terms of the lease agreement, we were obligated to provide a standby letter of credit in the amount of approximately $3.2 million as collateral for our full performance. In connection with this office lease, we received from the landlord leasehold incentives of approximately $6.0 million to make leasehold improvements to the leased office space. The leasehold incentive was recorded as leasehold improvements within property and equipment, net and as deferred rent within other liabilities in the consolidated balance sheets. The deferred rent liability is being amortized against rent expense over the term of the lease on a straight-line basis. The leasehold improvements are being amortized to expense over the shorter of the period from when the improvements were placed into service until the end of their respective useful lives or the lease term. As of July 31, 2014, $4.6 million lease incentives remained unamortized, of which $3.9 million was included in other liabilities and $0.7 million was included in accounts payable and accrued liabilities in the consolidated balance sheet. | |||||
Contract Manufacturer Commitments | |||||
The independent contract manufacturer that provides the substantial majority of our manufacturing, repair and supply chain operations procures components and builds our products based on our forecasts. These forecasts are based on estimates of future demand for our products, which are in turn based on historical trends and an analysis from our sales and marketing organizations, adjusted for overall market conditions. In order to reduce manufacturing lead times and plan for adequate component supply, we may issue purchase orders to this independent contract manufacturer which may not be cancelable. As of July 31, 2014, we had $6.9 million of open purchase orders with this independent contract manufacturer that may not be cancelable. | |||||
Guarantees | |||||
We have entered into agreements with some of our customers that contain indemnification provisions relating to potential situations where claims could be alleged that our products infringe the intellectual property rights of a third party. We have at our option and expense the ability to repair any infringement, replace product with a non-infringing equivalent-in-function product, or refund our customers the unamortized value of the product based on its estimated useful life, typically five years. Other guarantees or indemnification arrangements include guarantees of product and service performance and standby letters of credit for lease facilities and corporate credit cards. We have not recorded a liability related to these indemnification and guarantee provisions, and our guarantees and indemnification arrangements have not had any significant impact on our consolidated financial statements to date. | |||||
Loss Contingencies and Legal Proceedings | |||||
We are subject to the possibility of various loss contingencies arising in the ordinary course of business. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the range of loss can be reasonably estimated. However, the actual loss in any such contingency may be materially different from our estimates, which could result in the need to record additional expenses. If the amount of liability is not probable or the amount cannot be reasonably estimated, no accruals have been made. We regularly evaluate current information available to management to determine whether such accruals should be adjusted and whether new accruals are required in the periods presented. | |||||
From time to time, we are subject to various legal proceedings, claims and litigation arising in the ordinary course of business. We do not believe we are party to any currently pending legal proceedings the outcome of which would have a material adverse effect on our financial position, results of operations or cash flows. There can be no assurance that existing or future legal proceedings arising in the ordinary course of business or otherwise will not have a material adverse effect on our financial position, results of operations or cash flows. | |||||
Ansfield v. Infoblox Inc., et al., Case No. 3:14-cv-02500-VC (N.D. Cal.); Beqaj v. Infoblox Inc., et al., Case No. 3:14-cv-02564-VC (N.D. Cal.); and Achey, et al. v. Infoblox Inc., et al., Case No. 3:14-cv-02644-VC (N.D. Cal.). Beginning on May 30, 2014, the first of three putative securities class action suits was filed in the United States District Court for the Northern District of California against the Company and two of its officers. These suits, which have been deemed to be related cases, allege that defendants made materially false and misleading statements, or failed to disclose material facts, regarding the Company’s financial results, business, operations and prospects. The various suits assert claims covering the period from September 5, 2013 through May 29, 2014, are purportedly brought on behalf of purchasers of the Company's securities during that period, and seek compensatory damages, interest, costs and expenses, as well as equitable or other relief. On July 29, 2014, various members of the putative class filed motions for appointment as lead plaintiff(s) and approval of lead counsel, and also moved for consolidation of the various actions. On September 25, 2014, the lead plaintiffs were appointed and the suits consolidated. The defendants do not need to respond to any of the existing complaints. Instead, the lead plaintiffs will be permitted to file an amended consolidated complaint and defendants will thereafter respond to that amended pleading. No discovery has yet occurred; pursuant to the provisions of the Private Securities Litigation Reform Act of 1995, all discovery and other proceedings are stayed until and unless a motion to dismiss is denied (or until defendants choose to answer rather than filing a motion to dismiss). Due to the inherent uncertainties of litigation, we cannot accurately predict the ultimate outcome of this matter. We are unable at this time to determine whether the outcome of the litigation would have a material impact on our results of operations, financial condition or cash flows. | |||||
On April 16, 2013, Versata Software, Inc., or Versata, filed suit against us in the United States District Court for the District of Delaware in an action captioned Versata Software, Inc. F/K/A Trilogy Software, Inc.; and Versata Development Group, Inc. F/K/A Trilogy Development Group, Inc. v. Infoblox, Inc., Case No 1:13-cv-00678-UNA (D.Del.) (the “Action”). In the Action, Versata alleges that we directly and/or indirectly infringed U.S. Patent Nos. 6,834,282; 6,907,414; 7,363,593 and 7,426,481 by making, using, licensing, selling and offering for sale software products and related services including but not limited to Infoblox IP Address Management. In December 2013, we filed a motion to dismiss the Action. A hearing was held on the motion in August 2014 and the parties are awaiting the ruling on the motion. We continue to believe we have meritorious defenses to the claims asserted in these actions and intend to defend vigorously against them. We believe at this time that liabilities associated with these cases, while possible, are not probable, and therefore we have not recorded any accrual for them as of July 31, 2014 and 2013. Further, any possible range of loss cannot be reasonably estimated at this time. |

Our stock-based compensation plans include the 2012 Equity Incentive Plan (the “2012 Plan”), the 2005 Stock Plan (the “2005 Plan”), the 2003 Stock Plan (the “2003 Plan”), (collectively the “Plans”) and the 2012 Employee Stock Purchase Plan (the "ESPP"). Under the Plans, we have granted (or in the case of acquired plans, assumed) stock options and RSUs. We have issued common stock under the ESPP. | |||||||||||||||||
2012 Equity Incentive Plan | |||||||||||||||||
In April 2012, our board of directors approved and we adopted the 2012 Plan. It was subsequently amended in December 2012. Under the 2012 Plan, we have the ability to issue incentive stock options (“ISOs”), nonstatutory stock options (“NSOs”), restricted stock units, restricted stock awards (“RSAs”), stock appreciation rights (“SARs”), stock bonus awards or performance awards. ISOs may be granted to employees with exercise prices not less than the fair value of the common stock on the grant date as determined by the board of directors, and NSOs may be granted to employees, directors or consultants at exercise prices not less than 85% of the fair value of the common stock on the grant date as determined by the board of directors. If, at the time we grant an option, the optionee directly or by attribution owns stock possessing more than 10% of the total combined voting power of all classes of our stock, the exercise price must be at least 110% of the fair value of the common stock on the grant date as determined by the board of directors. Options, RSUs, RSAs, SARs, stock bonus awards and performance awards may be granted with vesting terms as determined by the board of directors and expire no more than ten years after the date of grant or earlier if employment or service is terminated. As of July 31, 2014, 4.1 million shares were available for grant under the 2012 Plan. | |||||||||||||||||
2003 Stock Plan | |||||||||||||||||
In March 2003, our board of directors approved and we adopted the 2003 Plan. As of April 20, 2012, no shares were available for grant under the 2003 Plan and all outstanding options would continue to be governed and remain outstanding in accordance with their existing terms. In addition, any shares subject to outstanding awards under the 2003 Plan that are issuable upon the exercise of options that expire or become unexercisable for any reason without having been exercised in full will be available for future grant and issuance under the 2012 Plan. | |||||||||||||||||
Employee Stock Purchase Plan | |||||||||||||||||
Concurrent with the effectiveness of our registration statement on Form S-1 on April 19, 2012, the ESPP became effective. It was subsequently amended in December 2012 and February 2014. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to plan limitations. The ESPP provides for a 24-month offering period comprised of four purchase periods of approximately six months. Employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock (i) at the date of commencement of the offering period or (ii) at the last day of the purchase period. Employees purchased approximately 0.6 million shares at an average price per share of $12.7 and 0.6 million shares at an average price per share of $13.80 under our ESPP during the years ended July 31, 2014 and 2013. There were no shares purchased by employees under the ESPP in fiscal year 2012. As of July 31, 2014, 1.3 million shares were available for future issuance under the ESPP. | |||||||||||||||||

Determination of Fair Value | |||||||||||||||||
The exercise price per share of our options to purchase common stock is the closing sale price per share of our common stock as quoted on the New York Stock Exchange on the date of grant. | |||||||||||||||||
The fair value of each grant of stock options was determined using the BSM option pricing model and assumptions discussed below. Each of the fair value inputs is subjective and generally requires significant judgment to determine. | |||||||||||||||||
Expected Term-The expected term represents the period that our stock-based awards are expected to be outstanding. For option grants that are considered to be “plain vanilla,” we determine the expected term using the simplified method as provided by the SEC. The simplified method deems the term to be the average of the time-to-vesting and the contractual life of the options. For other option grants, we estimate expected term using historical data on employee exercises and post-vesting employment termination behavior taking into account the contractual life of the award. The expected term for the ESPP is based on the term of the purchase period. | |||||||||||||||||
Risk-Free Interest Rate-The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the option's expected term. | |||||||||||||||||
Expected Volatility-Since we only have a short trading history of our common stock, we use a blended volatility to estimate expected volatility. The blended volatility includes a weighting of our historical volatility from the date of our IPO to the respective grant date and the average historical stock volatilities of several unrelated public companies within our industry that we consider to be comparable to our business over a period equivalent to the expected term of the stock option grants. | |||||||||||||||||
Dividend Rate-The expected dividend is based on our history and expected dividend payouts. The expected dividend yield is zero as the Company has historically paid no dividends and does not anticipate dividends to be paid in the future. | |||||||||||||||||
Forfeiture Rate-We estimate our forfeiture rate based on an analysis of our actual forfeitures and will continue to evaluate the adequacy of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover behavior and other factors. The impact from any forfeiture rate adjustment would be recognized in full in the period of adjustment, and if the actual number of future forfeitures differs from our estimates, we might be required to record adjustments to stock-based compensation in future periods. | |||||||||||||||||
Pre-IPO Common Stock Valuations | |||||||||||||||||
For all option grants prior to our IPO, the fair value of the common stock underlying the option grants was determined by our board of directors, with the assistance of management, which intended all options granted to be exercisable at a price per share not less than the per share fair value of our common stock underlying those options on the date of grant. Because there was no public market for our common stock before our IPO, our board of directors determined the fair value of the common stock at the time of grant of the option by considering a number of objective and subjective factors, including valuations of comparable companies, sales of our convertible preferred stock to unrelated third parties, operating and financial performance, the lack of liquidity of our capital stock and general and industry specific economic outlook. We did not grant stock options with an exercise price that was less than the fair value of the underlying common stock as determined at the time of grant by our board of directors. The fair value of the underlying common stock was determined by our board of directors until our IPO. | |||||||||||||||||

Restricted Stock Unit Activity | |||||||||||||||||
RSUs generally vest ratably over a period of four years from the date of grant subject to the employee’s continuing service to the Company over that period. Until vested, RSUs do not have the voting and dividend participation rights of common stock and the shares underlying the awards are not considered issued and outstanding. RSUs are converted into shares of the Company’s common stock upon vesting on a one-for-one basis. The cost of the RSUs is determined using the fair value of the Company’s common stock on the date of the grant. Compensation is recognized on a straight-line basis over the requisite service period of each grant adjusted for estimated forfeitures. | |||||||||||||||||

Recognition of deferred tax assets is appropriate when realization of these assets is more-likely-than-not. Based upon the weight of available evidence, which includes our historical operating performance and our ability to generate sufficient taxable income in the future, we recorded a full valuation allowance of $47.8 million and $41.4 million against the net U.S. deferred tax assets as of July 31, 2014 and 2013.We also recorded a $0.3 million valuation allowance against all Canadian deferred tax assets as of July 31, 2014 based upon the same above-mentioned criteria. The net valuation allowance increased by $6.7 million during the year ended July 31, 2014. The need for valuation allowance is subject to adjustment in future periods if sufficient positive evidence exists to support reversal. | ||||||||||||
As of July 31, 2014, we had U.S. federal net operating loss carryforwards of $147.2 million and California net operating loss carryforwards of $43.3 million. The federal net operating loss carryforwards will expire at various dates beginning in the year ending July 31, 2021 if not utilized. The California net operating loss carryforwards will expire at various dates beginning in the year ending July 31, 2018 if not utilized. Additionally, as of July 31, 2014, we had U.S. federal and California research and development credit carryforwards of $5.5 million and $4.9 million. Based on current tax laws, the federal R&D credit expired on December 31, 2013. The federal credit carryforwards will begin to expire at various dates beginning in 2023 while the California credit carryforwards are not subject to expiration. As of July 31, 2014, we also had Canadian scientific research and development credit carryforwards of $0.6 million which will expire beginning in 2034. | ||||||||||||
Net operating losses of approximately $113.9 million have not been included in the deferred tax asset table above as these net operating losses are attributable to excess tax benefits associated with equity related settlements. These benefits will not be recognized in the financial statements until they result in a reduction in taxes payable. When recognized in the financial statements, the tax benefit will be recorded to stockholders' equity. During the year ended July 31, 2014, we recognized approximately $0.2 million of excess tax benefits which resulted in a credit to stockholders' equity. | ||||||||||||
Utilization of our net operating loss and credit carryforwards may be subject to a substantial annual limitation provided for in the Internal Revenue Code and similar state codes. Such annual limitation could result in the expiration of net operating loss and credit carryforwards before utilization. We do not believe that such limitation rules will have a material impact on the financial statements. | ||||||||||||
Our policy with respect to our undistributed foreign subsidiaries' earnings is to consider those earnings to be indefinitely reinvested and, accordingly, no related provision for U.S. federal and state income taxes has been provided. Upon distribution of those earnings in the form of dividends or otherwise, we may be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes in the various countries. At July 31, 2014, the undistributed earnings approximated $2.4 million and the unrecorded deferred tax liability is estimated to be approximately $0.8 million. | ||||||||||||
Uncertain Tax Positions | ||||||||||||
As of July 31, 2014, 2013 and 2012, we had gross unrecognized tax benefits of $2.9 million, $2.3 million and $1.3 million. The balance of gross unrecognized tax benefits at July 31, 2014 includes approximately $0.2 million related to certain foreign and U.S. deferred tax assets with a corresponding valuation allowance. If recognized, the impact on our effective tax rate would not be material due to the full valuation allowance. We have not accrued interest and penalties related to unrecognized tax benefits reflected in the consolidated financial statements during the years ended July 31, 2014, 2013 and 2012. Our policy for classifying interest and penalties associated with unrecognized income tax benefits is to include such items in income tax expense. | ||||||||||||

Description of the Business and Summary of Significant Accounting Policies (Policies) | 12 Months Ended |
Jul. 31, 2014 | |
Accounting Policies [Abstract] | ' |
Basis of Presentation | ' |
Basis of Presentation | |
The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include all adjustments necessary for the fair presentation of our consolidated financial position, results of operations and cash flows for the periods presented. The accompanying consolidated financial statements include the accounts of Infoblox Inc. and our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. | |
Use of Estimates | ' |
Use of Estimates | |
The preparation of the accompanying consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Those management estimates and assumptions affect revenue recognition, determination of fair value of stock-based awards, valuation of goodwill and intangible assets acquired, impairment of goodwill and other intangible assets, amortization of intangible assets, contingencies and litigation, accounting for income taxes, including the valuation reserve on deferred tax assets and uncertain tax positions, allowances for doubtful accounts, warranty reserve and sales returns and valuation of inventory. We evaluate our estimates and assumptions on an ongoing basis using historical experience and other factors and adjust those estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ from these estimates and assumptions, and those differences could be material to the consolidated financial statements. | |
Concentration of Supply Risk with Contract Manufacturer | ' |
Concentration of Supply Risk with Contract Manufacturer | |
We outsource the substantial majority of our manufacturing, repair and supply chain management operations to one independent contract manufacturer. The inability of the manufacturer to fulfill our supply requirements could have a material and adverse effect on our business and consolidated financial statements. | |
In addition, our independent contract manufacturer procures components and manufactures our products based on our demand forecasts. These forecasts are based on our estimates of future demand for our products, which are in turn based on historical trends and an analysis from our sales and marketing organizations, adjusted for overall market conditions. We may be subject to the requirement to purchase inventory or to pay additional fees to the contract manufacturer if there is a significant difference in scheduled shipments or if the contract manufacturer holds inventory longer than a specified period. In 2012, we recorded a charge of $0.4 million for non-cancelable purchase commitments to our contract manufacturer for inventory which we deemed as excess and obsolete. This amount was recognized in products and licenses cost of revenue in the consolidated statement of operations for the year ended July 31, 2012. No significant charge was recorded in 2014 or 2013. | |
Concentrations of Credit Risk | ' |
Concentrations of Credit Risk | |
Financial instruments that potentially subject us to concentrations of credit risk consist of cash, cash equivalents, restricted cash and accounts receivable. Our cash, cash equivalents and restricted cash are invested in high-credit quality financial instruments held mainly in two US banks. Such deposits may be in excess of insured limits provided on such deposits. | |
We mitigate credit risk in respect to accounts receivable by performing ongoing credit evaluations of our customers and maintaining a reserve for potential credit losses. In addition, we generally require our customers to prepay for maintenance and support services to mitigate the risk of uncollectible accounts receivable. | |
Reverse Stock Split | ' |
Reverse Stock Split | |
On April 3, 2012, our board of directors approved a 1-for-3 reverse split of our common stock, which became effective on April 10, 2012. Upon the effectiveness of the reverse stock split, (i) every three shares of outstanding common stock were decreased to one share of common stock, (ii) the number of shares of common stock into which each outstanding option to purchase common stock is exercisable have been proportionally decreased on a 1-for-3 basis, (iii) the exercise price of each outstanding option to purchase common stock have been proportionately increased, and (iv) the conversion ratio for each share of preferred stock outstanding have been proportionately reduced. All of the share numbers, share prices, and exercise prices have been adjusted within these financial statements, on a retroactive basis, to reflect this 1-for-3 reverse stock split. | |
Cash and Cash Equivalents, Restricted Cash | ' |
Cash and Cash Equivalents | |
All highly liquid investments purchased with an original maturity of three months or less are classified as cash and cash equivalents. Cash and cash equivalents consist of cash on hand, demand deposits with banks, highly liquid investments in money market funds, U.S. Treasury securities and certificates of deposit which are readily convertible into cash. | |
Restricted Cash | |
Under our facility lease arrangements, we are required to maintain letters of credit from a U.S. bank as security for performance under these agreements. The letters of credit are generally invested in U.S. Treasury securities or money market funds or interest-bearing accounts in amounts equal to the letters of credit, which are classified as restricted cash on the consolidated balance sheets. Restricted cash, which is shown under non-current assets in the consolidated balance sheets, amounted to $3.5 million as of July 31, 2014 and 2013. | |
Short-term Investments | ' |
Short-term Investments | |
Investments with original maturities at purchase of greater than three months are classified as short-term or long-term investments. Management determines the appropriate classification of securities at the time of purchase and re-evaluates such classification as of each balance sheet date. | |
Our investments in publicly-traded debt securities are classified as available-for-sale. Available-for-sale investments are initially recorded at cost and periodically adjusted to fair value in the consolidated balance sheets. Unrealized gains and losses on these investments are reported as a separate component of accumulated other comprehensive income (loss). Realized gains and losses are determined based on the specific identification method and are reported in the consolidated statements of operations. The investments are adjusted for amortization of premiums and discounts to maturity and such amortization is included in other expense, net. | |
We recognize an impairment charge for available-for-sale investments when a decline in the fair value of our investments below the cost basis is determined to be other than temporary. We consider various factors in determining whether to recognize an impairment charge, including the length of time the investment has been in a loss position, the extent to which the fair value has been less than the cost basis, the investment's financial condition and near-term prospects, and our intent to sell, or whether it is more likely than not we will be required to sell, the investment before recovery of the investment's amortized cost basis. If we determine that the decline in an investment's fair value is other than temporary, the difference is recognized as an impairment loss in our consolidated statements of operations. During the year ended July 31, 2014, we did not consider any of our investments to be other-than-temporarily impaired. | |
Fair Value | ' |
Fair Value | |
Fair value is defined as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value, we consider the principal or most advantageous market in which we transact, and consider assumptions that market participants would use when pricing the asset or liability. We apply the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: | |
Level I - Quoted prices in active markets for identical assets or liabilities. | |
Level II - Quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. These inputs are valued using market based approaches. | |
Level III - Inputs are unobservable inputs based on management assumptions. These inputs, if any, are valued using internal financial models. | |
Inventory | ' |
Inventory | |
Inventories are stated at the lower of standard cost, which approximates actual cost (first-in, first-out), or market value (estimated net realizable value). The valuation of inventories at the lower of cost or market value requires the use of estimates regarding the amount of inventory that will be sold and the prices at which current inventory will be sold. These estimates are dependent on our assessment of current and expected orders from our customers. If actual market conditions are less favorable than those projected by management, inventory write-downs may be required. Our finished goods mainly consist of appliances that are used for the replacement of failed units under maintenance and support agreements and finished goods needed for our expanded depot requirements. We write down refurbished inventory based on the age of the units and number of hardware failures. During the years ended July 31, 2014, 2013 and 2012, inventory write-downs were $1.3 million, $1.1 million and $0.6 million. | |
Property and Equipment, Net | ' |
Property and Equipment, Net | |
Property and equipment, including leasehold improvements, are stated at cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets, which are two to three years. Leasehold improvements are amortized on a straight-line basis over the shorter of the estimated useful lives of the assets or the remaining lease term. Upon the retirement or disposition of property and equipment, the related costs and accumulated depreciation are removed from, and the resulting gain or loss is included in, the consolidated statements of operations. Repair and maintenance costs that do not extend the life or improve an asset are charged to expense as incurred. | |
Goodwill | ' |
Goodwill, Intangible Assets and Other Long-Lived Assets | |
Goodwill represents the future economic benefits arising from other assets acquired in a business combination or an acquisition that are not individually identified and separately recorded. The excess of the purchase price over the estimated fair value of net assets of businesses acquired in a business combination is recognized as goodwill. | |
Intangible assets consist of identifiable intangible assets, including developed technology, customer relationships, non-compete agreements, trademarks and patents, resulting from our acquisitions. Intangible assets are recorded at fair value, net of accumulated amortization. Intangible assets are amortized on a straight-line basis over their estimated useful lives. Amortization expense is included as a component of cost of products and licenses revenue and sales and marketing expense in the accompanying consolidated statements of operations. Amounts included in sales and marketing expense relate to amortization of intangible asset attributed to customer relationships. | |
Goodwill and other intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually during the fourth quarter. Such goodwill and other intangible assets may also be tested for impairment between annual tests in the presence of impairment indicators such as, but not limited to: (a) a significant adverse change in legal factors or in the business climate; (b) a substantial decline in our market capitalization, (c) an adverse action or assessment by a regulator; (d) unanticipated competition; (e) loss of key personnel; (f) a more likely-than-not expectation of sale or disposal of a reporting unit or a significant portion thereof; (g) a realignment of our resources or restructuring of our existing businesses in response to changes to industry and market conditions; (h) testing for recoverability of a significant asset group within a reporting unit; or (i) higher discount rate used in the impairment analysis as impacted by an increase in interest rates. | |
Impairment of Long-Lived Assets | ' |
Long-lived assets, such as property and equipment and intangible assets subject to depreciation and amortization, are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Among the factors and circumstances we considered in determining recoverability are: (i) a significant decrease in the market price of a long-lived asset; (ii) a significant adverse change in the extent or manner in which a long-lived asset is being used or in its physical condition; (iii) a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset, including an adverse action or assessment by a regulator; (iv) an accumulation of costs significantly in excess of the amount originally expected for the acquisition and (v) current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. | |
There have been no indicators of impairment of goodwill, intangible assets and other long-lived assets, and we did not record any impairment losses during the years ended July 31, 2014, 2013 and 2012. | |
Revenue Recognition | ' |
Revenue Recognition | |
We generate revenue from the sales or licensing of hardware and software products, support and maintenance, and other services through a direct sales force and indirect relationships with our partners. Revenue is recognized when all of the following criteria are met: | |
Persuasive evidence of an arrangement exists. Evidence of an arrangement generally consists of a purchase order issued pursuant to the terms and conditions of a distributor or value-added reseller agreement or, in limited cases, an end-user agreement. | |
Delivery or performance has occurred. We use shipping and related documents, distributor sell-through reports, or written evidence of customer acceptance, when applicable, to verify delivery or performance. We do not recognize product revenue until transfer of title and risk of loss, which generally is upon shipment to value-added resellers or end-users. | |
The sales price is fixed or determinable. We assess whether the sales price is fixed or determinable based on payment terms and whether the sales price is subject to refund or adjustment. | |
Collection is probable. We assess probability of collection on a customer-by-customer basis. We subject our customers to a credit review process that evaluates their financial condition and ability to pay for our products and services. If we conclude that collection is not probable, we do not recognize revenue until cash is received. | |
We recognize product revenue at the time of shipment provided that all other revenue recognition criteria have been met. Services revenue includes maintenance and support, training and consulting, and subscription services revenue. Maintenance and support revenue includes arrangements for software maintenance and technical support for our products and licenses. Maintenance is offered under renewable, fee-based contracts, which include 24-hour technical support, hardware repair and replacement parts, bug fixes, patches and unspecified upgrades on a when-and-if-available basis. Revenue from customer maintenance and support contracts and subscription services is deferred and recognized ratably over the contractual period, generally one to three years. Revenue from consulting and training is recognized as the services are completed. | |
We operate a multiple tier channel distribution model that includes distributors, value-added resellers and direct sales to end-users. For sales to value-added resellers and end-users, we recognize product revenue upon transfer of title and risk of loss, which is generally upon shipment. It is our practice to identify an end-user prior to shipment to a value-added reseller. For the end-users and value-added resellers, we generally have no significant contractual obligations for future performance, such as rights of return or pricing credits. However, we may on occasion enter into arrangements with end-users or value-added resellers that include some form of rights of return, rebates or price protection. Also, we may occasionally accept returns by end-users or value-added resellers to address customer satisfaction issues or solution fit issues even though there is no contractual provision for such returns. We record reductions to revenue for estimated product returns and pricing adjustments in the same period that the related revenue is recorded. The amount of these reductions is based on historical sales returns and price adjustments, specific provisions for returns, price protection or rebates in agreements, and other factors known at the time. Should actual product returns or pricing adjustments differ from estimates, additional reductions to revenue may be required. Distributor revenue is subject to agreements that may allow pricing credits, price protection, rebates and rights of return or involve international jurisdictions where the risk of returns or credits is considered to be high even though distributors do not have these contractual rights. As a consequence, the Company has determined that the sales price is not fixed or determinable at the time of shipment to a distributor and thus revenue and related costs of sales for these shipments are deferred until information is received from the distributor indicating that the product has been sold through to an end customer or value added reseller. | |
Multiple Element Arrangments | ' |
Multiple Element Arrangements | |
We enter into multiple element revenue arrangements in which a customer may purchase a combination of hardware, software, software upgrades, hardware and software maintenance and support, training and consulting, and subscription services. We account for multiple agreements with a single customer as one arrangement if the contractual terms and/or substance of those agreements indicate that they may be so closely related that they are, in effect, parts of a single arrangement. | |
Most of our products are hardware appliances containing software components that operate together to provide the essential functionality of the product. Therefore, the software sold with our hardware appliances are considered non-software deliverables and are not accounted for under the industry-specific software revenue recognition guidance. | |
Our products and licenses revenue also includes stand-alone software products. Stand-alone software may operate on our hardware appliances, but is not considered essential to the functionality of the hardware and continues to be subject to the industry-specific software revenue recognition guidance. The industry-specific software revenue recognition guidance includes the use of the residual method under which the amount of revenue allocated to delivered elements equals the total arrangement consideration less the aggregate fair value of any undelivered elements. If VSOE of fair value of one or more undelivered items does not exist, revenue from the entire arrangement is deferred and recognized at the earlier of: (i) delivery of those elements or (ii) when fair value can be established unless support and maintenance is the only undelivered element, in which case, the entire arrangement fee is recognized ratably over the contractual service period. | |
We provide unspecified software upgrades for most of our products, on a when-and-if available basis, through maintenance and support contracts. To the extent that the software being supported does not function together with the hardware to deliver the hardware’s essential functionality, these support arrangements would continue to be subject to the industry-specific software revenue recognition guidance. | |
We allocate the arrangement fee to each element based upon the relative selling price of that element and, if software and software-related (e.g., maintenance for the software element) elements are also included in the arrangement, we allocate the arrangement fee to each of those software and software-related elements as a group based on the relative selling price for those elements. After such allocations are made, the amount of the arrangement fee allocated to the software and software-related elements is accounted for using the residual method. When applying the relative selling price method, we determine the selling price for each element using vendor-specific objective evidence, or VSOE, of selling price, if it exists, or if not, third-party evidence, or TPE, of selling price, if it exists. If neither VSOE nor TPE of selling price exist for an element, we use our best estimate of selling price, or BESP, for that element. The revenue allocated to each element is then recognized when the basic revenue recognition criteria are met for that element. We limit the amount of revenue recognized for delivered elements to an amount that is not contingent upon future delivery of additional products or services or meeting of any specified performance conditions. | |
Whenever possible, we determine VSOE for each element based on historical stand-alone sales to third parties. For maintenance and support, training and consulting, and subscription services, we determine the VSOE of fair value based on our history of stand-alone sales demonstrating that a substantial majority of transactions fall within a narrow range for each service offering. | |
We historically have not been able to determine TPE for our products, maintenance and support, training or consulting services. TPE is determined based on competitor prices for similar elements when sold separately. Generally, our offerings contain a significant level of differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, our go-to-market strategy differs from that of our peers and we are unable to reliably determine what similar competitor products' selling prices are on a stand-alone basis. | |
When we are unable to establish the selling price of an element using VSOE or TPE, we use BESP in our allocation of consideration to various elements under the arrangement. The objective of BESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. The BESP is established based on internal and external factors, including pricing practices such as discounting, cost of products, the geographies in which we offer our products and services, and customer classes and distribution channels (e.g. distributor, value-added reseller and direct end-user). The determination of BESP is made through consultation with and approval by our management, taking into consideration our pricing model and go-to-market strategy. | |
For our non-software deliverables, we generally determine relative selling price based on BESP. However, for our maintenance and support, training and consulting, and subscription services, we generally use VSOE to determine relative selling price. When we are unable to establish selling price using VSOE for our maintenance and support, training and consulting, and subscription services, we use BESP in our allocation of arrangement consideration. | |
We regularly review VSOE and BESP data provided by actual transactions to update these estimates and the relative selling prices allocated to each element. | |
Deferred Revenue, Net | ' |
Deferred Revenue, Net | |
Deferred revenue, net represents amounts invoiced to customers, less related cost of revenue, for which the related revenue has not been recognized because one or more of the revenue recognition criteria have not been met. The current portion of deferred revenue represents the amounts that are expected to be recognized as revenue within one year of the consolidated balance sheet date. | |
Accounts Receivable and Allowance for Doubtful Accounts | ' |
Accounts Receivable and Allowance for Doubtful Accounts | |
Accounts receivable are recorded at invoiced amounts, net of allowances for doubtful accounts if applicable, and do not bear interest. | |
We evaluate the collectability of our accounts receivable based on known collection risks and historical experience. In circumstances where we are aware of a specific customer's inability to meet its financial obligations to us (e.g., bankruptcy filings or substantial downgrading of credit ratings), we record a specific reserve for bad debts against amounts due to reduce the net recognized receivable to the amount we reasonably believe will be collected. For all other customers, we record reserves for bad debts based on the length of time the receivables are past due and our historical experience of collections and write-offs. If circumstances change, such as higher-than-expected defaults or an unexpected material adverse change in a major customer's ability to meet its financial obligations, our estimate of the recoverability of the amounts due could be reduced by a material amount. | |
Concentration of Revenue and Accounts Receivable | ' |
Concentration of Revenue and Accounts Receivable | |
Significant customers are those which represent more than 10% of our total net revenue or gross accounts receivable balance at each respective balance sheet date. Exclusive Networks, a distributor, accounted for 10.5% and 11.5% of our total net revenue for the years ended July 31, 2014 and 2013. No single end customer, distributor or channel partner accounted for more than 10% of our net revenue in 2012. As of July 31, 2014 and 2013, Exclusive Networks accounted 12.8% and11.2% of our total gross accounts receivable. | |
Shipping and Handling | ' |
Shipping and Handling | |
Shipping charges billed to customers are included in revenue and the related shipping costs are included in cost of revenue. | |
Research and Development Costs | ' |
Research and Development Costs | |
Software development costs incurred in the research and development of new products and enhancements to existing products are charged to expense as incurred. Software development costs are capitalized after technological feasibility has been established. The period between achievement of technological feasibility, which we define as the establishment of a working model, and the general availability of such software to customers has been short, resulting in software development costs qualifying for capitalization being insignificant. Accordingly, we did not capitalize any software development costs during the years ended July 31, 2014, 2013 and 2012. | |
Stock-Based Compensation | ' |
Stock-Based Compensation | |
We recognize share-based compensation expense for all share-based payment awards including employee stock options, RSUs, and purchases under our ESPP based on each award's fair value on the grant date. We utilize the BSM option pricing model in order to determine the fair value of stock options and ESPP. The BSM option pricing model requires various highly subjective assumptions including volatility, expected award life, and risk-free interest rate. Since we only have a short trading history of our common stock (approximately 30 months since our IPO), we use a blended volatility to estimate expected volatility. The blended volatility includes a weighting of our historical volatility from the date of our IPO to the respective grant date and the average historical stock volatilities of several unrelated public companies within our industry that we consider to be comparable to our business over a period equivalent to the estimated life of our stock options. The expected life of an award is based on historical experience, the terms and conditions of the stock awards granted to employees, and the potential effect from options that have not been exercised. The fair value of the RSUs is determined using the closing price of our common stock on the date of the grant. Compensation is recognized on a straight-line basis over the requisite service period of each grant adjusted for estimated forfeitures. In addition, we are required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. We estimate the forfeiture rate based on historical experience and our expectations regarding future pre-vesting termination behavior of employees. | |
Warranty Costs | ' |
Warranty Costs | |
Our appliance hardware generally includes a one-year warranty, and our software generally carries a warranty of ninety days. Costs related to hardware replacement provided to customers under maintenance support agreements are included as services cost of revenue and recognized as these services are provided. | |
Advertising Costs | ' |
Advertising Costs | |
Advertising costs are charged to sales and marketing expenses as incurred in the consolidated statements of operations. Advertising expense during the years ended July 31, 2014, 2013 and 2012 was $1.3 million, $1.0 million and $1.1 million. | |
Foreign Currency | ' |
Foreign Currency | |
The functional currency of our foreign subsidiaries is the U.S. dollar. Transactions denominated in currencies other than the functional currency are remeasured at the average exchange rate in effect during the period. At the end of each reporting period, our subsidiaries' monetary assets and liabilities are remeasured to the functional currency using exchange rates in effect at the end of the reporting period. Non-monetary assets and liabilities are remeasured at historical exchange rates. Gains and losses related to remeasurement are recorded in other expense, net in the consolidated statements of operations. Foreign currency exchange losses included in other expense, net during the years ended July 31, 2014, 2013 and 2012 were $0.5 million, $0.8 million and $0.6 million | |
Income Taxes | ' |
Income Taxes | |
We account for income taxes under an asset and liability approach for deferred income taxes, which requires recognition of deferred income tax assets and liabilities for the expected future tax consequences of events that have been recognized in our consolidated financial statements, but have not been reflected in our taxable income. Estimates and judgments occur in the calculation of certain tax liabilities and in the determination of the recoverability of certain deferred income tax assets, which arise from temporary differences and carryforwards. Deferred income tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. We regularly assess the likelihood that our deferred income tax assets will be realized based on the realization guidance available. To the extent that we believe any amounts are not more-likely-than-not to be realized, we record a valuation allowance to reduce the deferred income tax assets. We regularly assess the need for the valuation allowance on our deferred tax assets, and to the extent that we determine that an adjustment is needed, such adjustment will be recorded in the period that the determination is made. | |
We regularly review our tax positions and benefits to be realized. We recognize tax liabilities based upon our estimate of whether, and the extent to which, additional taxes will be due when such estimates are more-likely-than-not to be sustained. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. We recognize interest and penalties related to income tax matters as income tax expense. For the years ended July 31, 2014, 2013 and 2012, we did not incur any interest or penalties associated with unrecognized tax benefits. | |
Segment Information | ' |
Segment Information | |
Operating segments are components of an enterprise for which separate financial information is available and is evaluated regularly by our chief operating decision maker in deciding how to allocate resources and assessing performance. Our chief operating decision maker is our Chief Executive Officer. | |
Our Chief Executive Officer reviews financial information presented on a consolidated basis, for purposes of allocating resources and evaluating financial performance. We have one business activity and there are no segment managers who are held accountable for operations, operating results beyond revenue goals or gross margins, or plans for levels or components below the consolidated unit level. Accordingly, we have a single reporting segment. | |
Recently Issued Accounting Pronouncements | ' |
Recently Issued Accounting Pronouncements | |
In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-11, Income Taxes (Topic 740), Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). ASU 2013-11 provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, similar tax loss, or tax credit carryforward exists. This new standard requires the netting of unrecognized tax benefits (“UTBs”) against a deferred tax asset for a loss or other carryforward that would apply in settlement of the uncertain tax positions. UTBs will be netted against all available same-jurisdiction loss or other tax carryforwards that would be utilized, rather than only against carryforwards that are created by the UTBs. We adopted ASU 2013-11 during the first quarter of fiscal 2014 and the adoption did not have any impact on our consolidated financial position or results of operations. | |
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. The standard is effective for us beginning the first quarter of fiscal 2018, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements and have not yet determined the method by which we will adopt the standard in fiscal 2018. |
