Summary of Significant Accounting Policies (Policies)

3 Months Ended

Sep. 30, 2012

The Company's revenue is primarily derived from sales of networking products, which are tangible products containing software and non-software components that function together to deliver the tangible product's essential functionality. In addition to tangible products, the Company's sales arrangements may include other deliverables such as standalone software licenses, or service offerings. For multiple deliverable arrangements, the Company recognizes revenue in accordance with the accounting standard for multiple deliverable revenue arrangements, which provides guidance on whether multiple deliverables exist, how deliverables in an arrangement should be separated, and how consideration should be allocated. Software revenue recognition guidance is applied to the sales of the Company's standalone software products, including software upgrades and software that is not essential to the functionality of the hardware with which it is sold.

Pursuant to the guidance of the accounting standard for multiple deliverable revenue arrangements, when the Company's sales arrangements contain multiple elements, such as products, software licenses, maintenance agreements, or professional services, the Company determines the standalone selling price for each element based on a selling price hierarchy. The application of the multiple deliverable revenue accounting standard does not change the units of accounting for the Company's multiple element arrangements. Under the selling price hierarchy, the selling price for each deliverable is based on the Company's vendor-specific objective evidence (“VSOE”), which is determined by a substantial majority of the Company's historical standalone sales transactions for a product or service falling within a narrow range. If VSOE is not available due to a lack of standalone sales transactions or lack of pricing within a narrow range, then third party evidence (“TPE”), as determined by the standalone pricing of competitive vendor products in similar markets, is used, if available. TPE typically is difficult to establish due to the proprietary differences of competitive products and difficulty in obtaining reliable competitive standalone pricing information. When neither VSOE nor TPE is available, the Company determines its best estimate of standalone selling price (“ESP”) for a product or service and does so by considering several factors including, but not limited to, the 12-month historical median sales price, sales channel, geography, gross margin objective, competitive product pricing, and product life cycle. In consideration of all relevant pricing factors, the Company applies management judgment to determine the Company's best estimate of selling price through consultation with and formal approval by the Company's management for all products and services for which neither VSOE nor TPE is available. Generally the standalone selling price of services is determined using VSOE and the standalone selling price of other deliverables is determined by using ESP. The Company regularly reviews VSOE, TPE and ESP for all of its products and services and maintains internal controls over the establishment and updates of these estimates.

In accordance with the software revenue recognition accounting standard, the Company continues to recognize revenue for software using the residual method for its sale of standalone software products, including optional software upgrades and other software that is not essential to the functionality of the hardware with which it is sold. After allocation of the relative selling price to each element of the arrangement, the Company recognizes revenue in accordance with the Company's policies for product, software, and service revenue recognition.

Available-for-Sale Securities

The Company considers highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents. Investments with maturities of greater than three months, but less than one year at the balance sheet date are classified as Short Term Investments. Investments with maturities of greater than one year at balance sheet date are classified as Marketable Securities. Except for direct obligations of the United States government, securities issued by agencies of the United States government, and money market funds, the Company diversifies its investments by limiting its holdings with any individual issuer.

Investments include available-for-sale investment-grade debt securities that the Company carries at fair value. The Company accumulates unrealized gains and losses on the Company's available-for-sale debt securities, net of tax, in accumulated other comprehensive income in the stockholders' equity section of its balance sheets. Such an unrealized gain or loss does not reduce net income for the applicable accounting period. If the fair value of an available-for-sale debt instrument is less than its amortized cost basis, an other-than-temporary impairment is triggered in circumstances where (1) the Company intends to sell the instrument, (2) it is more likely than not that the Company will be required to sell the instrument before recovery of its amortized cost basis, or (3) the Company does not expect to recover the entire amortized cost basis of the instrument (that is, a credit loss exists). If the Company intends to sell or it is more likely than not that the Company will be required to sell the available-for-sale debt instrument before recovery of its amortized cost basis, the Company recognizes an other-than-temporary impairment in earnings equal to the entire difference between the debt instruments' amortized cost basis and its fair value. For available-for-sale debt instruments that are considered other-than-temporarily impaired due to the existence of a credit loss, if the Company does not intend to sell and it is not more likely than not that the Company will be required to sell the instrument before recovery of its remaining amortized cost basis (amortized cost basis less any current-period credit loss), the Company separates the amount of the impairment into the amount that is credit related and the amount due to all other factors. The credit loss component is recognized in earnings and is the difference between the debt instrument's amortized cost basis and the present value of its expected future cash flows. The remaining difference between the debt instrument's fair value and the present value of future expected cash flows is due to factors that are not credit related and is recognized in other comprehensive income.

The following table presents the Company’s investments’ gross unrealized losses and fair values, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position.



	Less than 12 months					12 months or more				Total
	Fair Value		Unrealized Losses			Fair Value		Unrealized Losses		Fair Value		Unrealized Losses

The Company determines the basis of the cost of a security sold or the amount reclassified out of accumulated other comprehensive income into earnings using the specific identification method. During the three months ended September 30, 2012 and October 2, 2011, realized gains or losses recognized on the sale of investments were not significant. As of September 30, 2012, three out of sixty-three investment securities had unrealized losses. The unrealized gains / (losses) on the Company’s investments were caused by interest rate fluctuations. Substantially all of the Company’s available-for-sale investments are investment grade government and corporate debt securities that have maturities of less than three years. The Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of its amortized costs.

Inventories

Inventory is stated at the lower of cost or market. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. The Company reduces the carrying value of inventory to net realizable value based on excess and obsolete inventories which are primarily determined by age of inventory and future demand forecasts. At the point of the loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Any written down or obsolete inventory subsequently sold has not had a material impact on gross profit for any of the periods disclosed.

Long-Lived Assets

Long-lived assets include property and equipment, intangible assets, and service inventory. Property and equipment, and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets or asset groups may not be recoverable. If such facts and circumstances exist, the Company assesses the recoverability of these assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets. The Company reduces the carrying value of service inventory to net realizable value based on excess and obsolete inventories which are primarily determined by age of inventory and future demand forecasts.

Deferred Revenue, Net

Deferred revenue, net represents amounts for (i) deferred services revenue (support arrangements, professional services and training), and (ii) deferred product revenue net of the related cost of revenue when the revenue recognition criteria have not been met. The following table summarizes deferred revenue, net at September 30, 2012 and June 30, 2012, respectively (in thousands):



	September 30, 2012			June 30, 2012
Deferred services	$	35,863		$	37,708
Deferred product:
Deferred revenue	1,798			2,236

Guarantees and Product Warranties

Upon issuance of a standard product warranty, the Company discloses and recognizes a liability for the obligation it assumes under the warranty. The following table summarizes the activity related to the Company’s product warranty liability during the three months ended September 30, 2012 and October 2, 2011:



	Three Months Ended
	September 30, 2012			October 2, 2011
Balance beginning of period	$	2,871		$	2,640
New warranties issued	1,561			1,648
Warranty expenditures	(1,461		)	(1,586		)
Balance end of period	$	2,971		$	2,702

The Company’s standard hardware warranty period is typically 12 months from the date of shipment to end-users and 90 days for software. For certain access products, the Company offers a limited lifetime hardware warranty commencing on the date of shipment from the Company and ending five (5) years following the Company’s announcement of the end of sale of such product. Upon shipment of products to its customers, the Company estimates expenses for the cost to repair or replace products that may be returned under warranty and accrue a liability in cost of product revenue for this amount. The determination of the Company’s warranty requirements is based on actual historical experience with the product or product family, estimates of repair and replacement costs and any product warranty problems that are identified after shipment. The Company estimates and adjusts these accruals at each balance sheet date in accordance with changes in these factors.

In the normal course of business to facilitate sales of its products, the Company indemnifies its resellers and end-user customers with respect to certain matters. The Company has agreed to hold the customer harmless against losses arising from a breach of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. It is not possible to estimate the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material impact on its operating results or financial position.

Fair Value

The Company measures certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, available-for-sale securities, trading securities and foreign currency derivatives. Fair value is measured based on a fair value hierarchy following three levels of inputs, of which the first two are considered observable and the last unobservable:



• Level 1			Quoted prices in active markets for identical assets or liabilities;

• Level 2			Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and

• Level 3			Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Legal Proceedings

In accordance with applicable accounting guidance, the Company records accruals for certain of its outstanding legal proceedings, investigations or claims when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. The Company evaluates, at least on a quarterly basis, developments in legal proceedings, investigations or claims that could affect the amount of any accrual, as well as any developments that would result in a loss contingency to become both probable and reasonably estimable. When a loss contingency is not both probable and reasonably estimable, the Company does not record a loss accrual. However, if the loss (or an additional loss in excess of any prior accrual) is at least a reasonable possibility and material, then the Company would disclose an estimate of the possible loss or range of loss, if such estimate can be made, or disclose that an estimate cannot be made. The assessment whether a loss is probable or a reasonable possibility, and whether the loss or a range of loss is estimable, involves a series of complex judgments about future events. Even if a loss is reasonably possible, the Company may not be able to estimate a range of possible loss, particularly where (i) the damages sought are substantial or indeterminate, (ii) the proceedings are in the early stages, or (iii) the matters involve novel or unsettled legal theories or a large number of parties. In such cases, there is considerable uncertainty regarding the ultimate resolution of such matters, including the amount of any possible loss, fine or penalty. Accordingly, for current proceedings, the Company is currently unable to estimate any reasonably possible loss or range of possible loss. However, an adverse resolution of one or more of such matters could have a material adverse effect on the Company's results of operations in a particular quarter or fiscal year.

Earnings Per Share

Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period, less shares subject to repurchase, and excludes any dilutive effects of options, warrants and unvested restricted stock. Dilutive earnings per share is calculated by dividing net income by the weighted average number of common shares used in the basic earnings per share calculation plus the dilutive effect of shares subject to repurchase, options, warrants and unvested restricted stock.

Potentially dilutive common shares from employee incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options, the assumed vesting of outstanding restricted stock units, and the assumed issuance of common stock under the stock purchase plan. Weighted stock options outstanding with an exercise price higher than the Company's average stock price for the periods presented are excluded from the calculation of diluted net income per share since the effect of including them would have been anti-dilutive due to the net income position of the Company during the periods presented.
