[1] | Under the percentage-of-completion method, we recognized revenues of $111.0 and $78.8 in the three months ended October 1, 2016 and September 26, 2015, respectively. For the nine months ended October 1, 2016 and September 26, 2015, revenues under the percentage-of-completion method were $347.6 and $325.1, respectively. Costs and estimated earnings in excess of billings on uncompleted contracts accounted for under the percentage-of-completion method were $91.3 and $106.3 as of October 1, 2016 and December 31, 2015, respectively, and are reported as a component of ‘‘Accounts receivable, net’’ in the condensed consolidated balance sheets. Billings in excess of costs and estimated earnings on uncompleted contracts accounted for under the percentage-of-completion method were $75.8 and $116.3 as of October 1, 2016 and December 31, 2015, respectively, and are reported as a component of ‘‘Accrued expenses’’ in the condensed consolidated balance sheets.
[2] | As further discussed in Note 13, during the three months ended September 26, 2015, we made revisions to our estimates of expected revenues and profits on our large power projects in South Africa. As a result of these revisions, we reduced revenue and segment income by $57.2 and $95.0, respectively, during the three and nine months ended September 26, 2015.
