new software licenses. In addition, substantially all of our customers renew their software license updates and product support contracts annually.

 

Many of our software arrangements include consulting implementation services sold separately under consulting engagement contracts. Consulting revenues from these arrangements are generally accounted for separately from new software license revenues because the arrangements qualify as service transactions as defined in SOP 97-2. The more significant factors considered in determining whether the revenue should be accounted for separately include the nature of services (i.e., consideration of whether the services are essential to the functionality of the licensed product), degree of risk, availability of services from other vendors, timing of payments and impact of milestones or acceptance criteria on the realizability of the software license fee. Revenues for consulting services are generally recognized as the services are performed. If there is a significant uncertainty about the project completion or receipt of payment for the consulting services, revenues are deferred until the uncertainty is sufficiently resolved. We estimate the proportional performance on contracts with fixed or “not to exceed” fees on a monthly basis utilizing hours incurred to date as a percentage of total estimated hours to complete the project. If we do not have a sufficient basis to measure progress towards completion, revenue is recognized when we receive final acceptance from the customer. When total cost estimates exceed revenues, we accrue for the estimated losses immediately using cost estimates that are based upon an average fully burdened daily rate applicable to the consulting organization delivering the services. The complexity of the estimation process and factors relating to the assumptions, risks and uncertainties inherent with the application of the proportional performance method of accounting affects the amounts of revenues and related expenses reported in our consolidated financial statements. A number of internal and external factors can affect our estimates, including labor rates, utilization and efficiency variances and specification and testing requirement changes.

 

If an arrangement does not qualify for separate accounting of the software license and consulting transactions, then new software license revenues are generally recognized together with the consulting services based on contract accounting using either the percentage-of-completion or completed-contract method. Contract accounting is applied to any arrangements: (1) that include milestones or customer specific acceptance criteria that may affect collection of the software license fees; (2) where services include significant modification or customization of the software; (3) where significant consulting services are provided for in the software license contract without additional charge or are substantially discounted; or (4) where the software license payment is tied to the performance of consulting services.
