Deferred Revenue-entry of right-to-use contracts and Deferred Commission Expense

Upfront payments received upon the entry of right-to-use contracts are recognized in accordance with FASB ASC 605. We recognize the up-front non-refundable payments over the estimated customer life, which, based on historical attrition rates, we have estimated to be between one to 31 years. The commissions paid on the entry of right-to-use contracts are deferred and amortized over the same period as the related revenue.
