Inventory Valuation

The Company’s inventory balances as of March 31, 2016 and June 30, 2015 were $$52.8 million and $58.0 million, respectively. The Company values its inventory at lower of cost or market. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. The Company has established inventory allowances primarily determined by the age of inventory or when conditions exist that suggest that inventory may be in excess of anticipated demand or is obsolete based upon assumptions about future demand. 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 margin for any of the periods disclosed.

Guarantees and Product Warranties

Networking products may contain undetected hardware or software errors when new products or new versions or updates of existing products are released to the marketplace. In the past, we had experienced such errors in connection with products and product updates. 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.

Upon issuance of a standard product warranty, the Company discloses and recognizes a liability for the obligations it assumes under the product warranty. The following table summarizes the activity related to the Company’s product warranty liability during the three and nine months ended March 31, 2016 and 2015 (in thousands):

	Three Months Ended						Nine Months Ended
	March 31, 2016			March 31, 2015			March 31, 2016			March 31, 2015

To facilitate sales of its products in the normal course of business, 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.

Advertising

Cooperative advertising expenses are recorded as marketing expenses to the extent that an advertising benefit separate from the revenue transaction can be identified and the cash paid does not exceed the fair value of that advertising benefit received. Cooperative advertising obligations with customers are accrued and the costs expensed at the time the related revenue is recognized. If the Company does not meet the criteria for recognizing such cooperative advertising obligations as marketing expense, the costs are recorded as a reduction of revenue. All other advertising costs are expensed as incurred. Advertising expenses for three and nine months ended March 31, 2016 and 2015, were immaterial.

Concentrations

The Company may be subject to concentration of credit risk as a result of certain financial instruments consisting of accounts receivable and short-term investments. The Company does not invest an amount exceeding 10% of its combined cash or cash equivalents in the securities of any one obligor or maker, except for obligations of the United States government, obligations of United States government agencies and money market accounts.

The Company performs ongoing credit evaluations of its customers and generally does not require collateral in exchange for credit.
