18. Commitments and Contingencies

Operating Leases

We lease various equipment, vehicles and office space in the U.S. and internationally.

Future annual minimum lease payments under all non-cancelable operating leases with an initial term in excess of one year as of April 24, 2015 are as follows (in millions):

			2016				2017				2018				2019				2020			Thereafter				Total
Operating lease commitments		$	61.9			$	44.0			$	29.6			$	21.0			$	17.3			$	31.7			$	205.5

Rent expense under all cancellable and non-cancelable operating leases was $67.0 million, $65.5 million and $64.9 million in fiscal 2015, 2014 and 2013, respectively.

Purchase Orders and Other Commitments

In the ordinary course of business, we make commitments to third-party contract manufacturers, to manage manufacturer lead times and meet product forecasts, and to other parties, to purchase various key components used in the manufacture of our products. We establish accruals for estimated losses on non-cancellable purchase commitments for components to the extent we believe it is probable that such components will not be utilized in future operations. To the extent that such forecasts are not achieved, our commitments and associated accruals may change. As of April 24, 2015, we had $295.0 million in non-cancelable purchase commitments with our contract manufacturers. In addition, we recorded a liability for firm, non-cancelable and unconditional purchase commitments with contract manufacturers for quantities in excess of our future demand forecasts through a charge to cost of product revenues. As of April 24, 2015 and April 25, 2014, such liability amounted to $16.9 million and $11.5 million, respectively, and is included in accrued expenses in our consolidated balance sheets.

In addition to commitments with contract manufacturers and component suppliers, we have open purchase orders and construction related obligations associated with our ordinary course of business for which we have not received goods or services. As of April 24, 2015, we had $60.0 million in construction related obligations and $211.0 million in other purchase obligations.

During the ordinary course of business, we provide standby letters of credit or other guarantee instruments to third parties as required for certain transactions initiated either by us or our subsidiaries. As of April 24, 2015, our financial guarantees of $9.3 million that were not recorded on our consolidated balance sheets consisted primarily of standby letters of credit and surety bonds.

Financing Guarantees

Some of our customers have entered into recourse and non-recourse financing leasing arrangements using third-party financing companies, and in some situations, we enter into customer financing arrangements for our products and services that are contemporaneously sold on a recourse or non-recourse basis to third-party financing companies. Under the terms of recourse leases, which are generally three years or less, we remain liable for the aggregate unpaid remaining lease payments to the third-party leasing companies in the event of end-user customer default. These arrangements are generally collateralized by a security interest in the underlying assets. Under the terms of the non-recourse leases, we do not have any continuing obligations or liabilities to the third-party financing companies. Where we provide a guarantee for recourse leases, we defer revenues subject to the industry-specific software revenue recognition guidance, and recognize revenues for non-software deliverables in accordance with our multiple deliverable revenue arrangement policy. In connection with certain recourse financing arrangements, we receive advance payments associated with undelivered elements that are subject to customer refund rights. We defer revenue associated with these advance payments until the related refund rights expire and we perform the services. As of April 24, 2015 and April 25, 2014, the aggregate amount by which such contingencies exceeded the associated deferred revenue was not significant. To date, we have not experienced material losses under our lease financing programs or other financing arrangements.

Indemnification Agreements

We enter into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, we agree to defend and indemnify other parties, primarily our customers or business partners or subcontractors, for damages and reasonable costs incurred in any suit or claim brought against them alleging that our products sold to them infringe any U.S. patent, copyright, trade secret, or similar right. If a product becomes the subject of an infringement claim, we may, at our option: (i) replace the product with another non-infringing product that provides substantially similar performance; (ii) modify the infringing product so that it no longer infringes but remains functionally equivalent; (iii) obtain the right for the customer to continue using the product at our expense and for the reseller to continue selling the product; (iv) take back the infringing product and refund to the customer the purchase price paid less depreciation amortized on a straight-line basis. We have not been required to make material payments pursuant to these provisions historically. We have not recorded any liability at April 24, 2015 related to these guarantees since the maximum amount of potential future payments under such guarantees, indemnities and warranties is not determinable, other than as described above.

Legal Contingencies

When a loss is considered probable and reasonably estimable, we record a liability in the amount of our best estimate for the ultimate loss. However, the likelihood of a loss with respect to a particular contingency is often difficult to predict and determining a meaningful estimate of the loss or a range of loss may not be practicable based on the information available and the potential effect of future events and decisions by third parties that will determine the ultimate resolution of the contingency.

We are subject to various legal proceedings and claims that arise in the normal course of business. No accrual has been recorded as of April 24, 2015 related to such matters as they are not probable and/or reasonably estimable.
