recognition guidance , including industry-specific guidance . the guidance also changes the accounting for certain contract costs and revises the criteria for determining if an entity is acting as a principal or agent in certain arrangements . the key changes in the standard that impact the company 2019s revenue recognition relate to the presentation of certain revenue contracts and associated contract costs . the most significant of these changes relates to the presentation of certain distribution costs , which are currently presented net against revenues ( contra-revenue ) and will be presented as an expense on a gross basis . the company adopted asu 2014-09 effective january 1 , 2018 on a full retrospective basis , which will require 2016 and 2017 to be restated in future filings . the cumulative effect adjustment to the 2016 opening retained earnings was not material . the company currently expects the net gross up to revenue to be approximately $ 1 billion with a corresponding gross up to expense for both 2016 and 2017 . consequently , the company expects its gaap operating margin to decline upon adoption due to the gross up of revenue . however , no material impact is expected on the company 2019s as adjusted operating margin . for accounting pronouncements that the company adopted during the year ended december 31 , 2017 and for additional recent
