These estimates include, but are not limited to, assessing the collectability of accounts receivable, estimation of the value of stock-based compensation awards, fair value of assets and liabilities acquired, impairment of goodwill and intangible assets, useful lives of intangible assets, vendor specific objective evidence (“VSOE”) of fair value related to revenue recognition, and income taxes.</span></div>

Deferred maintenance revenue represents customer billings, paid up front, generally annually at the beginning of each maintenance period, with revenue recognized ratably over such period. For certain other licensing arrangements, revenue attributable to undelivered elements, including post-contract customer support which typically includes telephone support and the right to receive unspecified upgrades and enhancements of software on a when-and-if-available basis, is based upon the sales price of those elements when sold separately and is recognized ratably on a straight-line basis over the term of the arrangement.</span></div>
