9. Maintenance Contracts

The Company offers maintenance contracts to its customers at the time they enter into a product license agreement and renew those contracts at the customers' option, generally annually thereafter. These maintenance contracts are priced as a percentage of the value of the related license agreement. The specific terms and conditions of these initial maintenance contracts and subsequent renewals vary depending upon the product licensed and the country in which the Company does business. Generally, maintenance contracts provide the customer with unspecified product maintenance updates and customer support services. Revenue from maintenance contracts is initially deferred and then recognized ratably over the term of the agreements.
