2. Basis of preparation (continued) Information about significant management estimates and assumptions that have a risk of resulting in a significant adjustment is included in Note 3 as well as the following notes: Estimated unbilled revenue (Note 5) Net realizable value of natural gas in storage held for resale (Note 6) Fair value of financial and derivative instruments (Note 9) Useful lives and amortization rates for intangible assets (Note 11) Useful lives and depreciation rates for property, plant and equipment (Note 12)
Estimated unearned customer capital contributions (Note 16) Estimated future cost of decommissioning liabilities (Note 18)
During the period ended March 31, 2016, the Corporation modified its estimate of deferred revenue. As the Corporation’s customer capital contributions are often subject to refunds over a specified period, an estimate of these refunds remains in deferred revenue until the eligible refund period expires. Under the new methodology, the Corporation calculated the estimated refunds based on a customer’s requested delivery capacity rather than management’s estimate of future customer usage. This change is a more accurate reflection of the amount that is likely to be refunded, and as such, is an improvement over the previous estimation process. As a change in estimate, the impact was applied prospectively effective January 1, 2015 and resulted in approximately $25 million of additional customer contribution revenue for the 15-month period. As the estimate is dependent on future customer capital contributions received, the impact of the change to future periods is uncertain at the end of the reporting period. 3.
