[2] (2)There has been a change in presentation relating to 2014 due to the adoption of guidance issued by the FASB that requires the presentation of debt issuance costs in financial statements as a direct reduction of related debt liabilities with amortization of debt issuance costs reported as interest expense. Previously debt issuance costs were reported as part of deferred charges. Genesis adopted this guidance in Q4 2015 and retrospectively adjusted the presentation of related costs as needed. For more information please refer to the discussion of recently issued accounting pronouncements in the Summary of Accounting Policies (Note 2).
