[1] | During 2018, we adopted ASU 2014-09, which clarifies the principles used to recognize revenue. We elected to apply the modified retrospective method of adoption; therefore, results for reporting periods after December 28, 2017 are presented under the new guidance and prior period amounts have not been adjusted. The increase in operating revenue was primarily the result of recognizing advertising revenue on a gross basis versus recording it on a net basis as previously reported. See Note 3 to our Consolidated Financial Statements for details.
[2] | As disclosed in Note 2, prior period amounts have not been adjusted under the modified retrospective method of adoption of Topic 606.
[3] | Per share amounts do not necessarily sum to the total year amounts due to changes in shares outstanding and rounding
[4] | Per share amounts do not necessarily sum to the total year amounts due to changes in shares outstanding and rounding.
