Amendments to Presentation of Retirement Benefits - In March 2017, the FASB issued an accounting standards update that requires certain changes in classification of components of net periodic pension and postretirement benefit costs within the income statement and allows only the service cost component to be eligible for capitalization. This standards update will be applied using the retrospective approach for presentation of the components of net periodic pension and postretirement benefit costs and the prospective approach for capitalization of service cost. NEE and FPL will apply this standards update on January 1, 2018, and are currently evaluating the impact the adoption will have on their consolidated financial statements.
