[1] As a result of adoption of ASC Topic 606, the Company determined that the deferred revenue associated with the ESA and Common Unit Adjustment agreement should be amortized on a straight-line basis versus the units of revenue method followed prior to adoption. The Company recorded a reduction in the deferred revenue balance and a cumulative effect of a change in accounting principle in retained earnings (see also Note 6). See Note 3 for further discussion of the impact of the adoption of ASC Topic 606.
