⁽¹⁾ During the fourth quarter of 2017, we changed our presentation for certain cost reimbursements that were previously netted as an offset to affiliate expense. We now present these reimbursements gross in affiliate income. As a result, we have reclassified prior year amounts in order to conform to the current year presentation. See Note 21, "Related Party Transactions," in the accompanying consolidated financial statements for additional information. The following table reflects the impact of this reclassification for the periods below:

	2017			2016
	Third	Second	First	Fourth	Third	Second	First
	(in millions)
Increase in other revenues	25	29	32	25	18	14	15
