7. Commitments and Contingencies

Leases

We maintain office facilities in various locations under operating leases with expiration dates from fiscal 2014 to fiscal 2022, some of which have renewal options of one to five years. Our leased office facilities are located in China, Finland, Hong Kong, Japan, Korea, Switzerland, Taiwan, and the United States. We recognized rent expense on a straight-line basis of $4.6 million, $4.3 million, and $4.0 million for fiscal 2013, 2012, and 2011, respectively.

The aggregate future minimum rental commitments in future fiscal years for noncancelable operating leases with initial or remaining terms in excess of one year were as follows (in thousands):

2014	$	3,133
2015		1,966
2016		997
2017		620
2018		443
Thereafter		1,408

Contingencies

We have in the past and may in the future receive notices from third parties that claim our products infringe their intellectual property rights. We cannot be certain that our technologies and products do not and will not infringe issued patents or other proprietary rights of third parties.

Any infringement claims, with or without merit, could result in significant litigation costs and diversion of management and financial resources, including the payment of damages, which could have a material adverse effect on our business, financial condition, and results of operations.

Indemnifications

In connection with certain third-party agreements we have executed in the past, we are obligated to indemnify the third party in connection with any technology infringement by us. We have also entered into indemnification agreements with our officers and directors. Maximum potential future payments cannot be estimated because these agreements do not have a maximum stated liability. However, historical costs related to these indemnification provisions have not been significant. We have not recorded any liability in our consolidated financial statements for such indemnification obligations.

Line of Credit

We have an unsecured $50.0 million working capital line of credit with Wells Fargo Bank. The Wells Fargo Bank revolving line of credit, which expires on September 1, 2013, has an interest rate equal to the prime lending rate or 250 basis points above LIBOR, depending on whether we choose a variable or fixed rate, respectively. We did not borrow any amounts under the line of credit during fiscal 2013. We are currently negotiating the renewal of this line of credit for another year.
