Deferred product revenue relates to arrangements where not all revenue recognition criteria have been met. Deferred support and professional services revenue primarily represents customer payments made in advance for support and professional services contracts. Support contracts are typically billed on an annual basis in advance and revenue is recognized ratably over the support period, typically one to five years. Non-current product deferred revenue relates to software products sold as part of a multiple-element arrangement for which Vendor Specific Objective Evidence ("VSOE") had not been established. Revenue for these software products is recognized ratably over the related support period. The primary changes in the deferred revenue balances are due to quarter-end inventory stocking orders of our value-added distributors, growth of annual maintenance contracts from customers, and transactions which have certain acceptance or deployment provisions that will be recognized as revenue when revenue recognition criteria are met.
