REVENUES FROM CONTRACTS

Disaggregated Revenues

We disaggregate revenue from contracts with customers by major product line and based on the timing of recognition for each of our reportable segments and other operating segments, as we believe such disaggregation best depicts how the nature, amount, timing, and uncertainty of our revenues and cash flows are effected by economic factors, with such disaggregation presented below for the three months ended March 30, 2019 and March 31, 2018:

Contract Balances

Our customers are invoiced for products and services at the time of delivery or based on contractual milestones, resulting in outstanding receivables with payment terms from these customers (“Contract Accounts Receivable”). In some cases, the timing of revenue recognition, particularly for revenue recognized over time, differs from when such amounts are invoiced to customers, resulting in a contract asset (revenue recognition precedes the invoicing of the related revenue amount) or a contract liability (payment from the customer precedes recognition of the related revenue amount). Contract assets and liabilities are generally classified as current. On a contract-by-contract basis, the contract assets and contract liabilities are reported net within our condensed consolidated balance sheets. Our contract balances consisted of the following as of March 30, 2019 and December 31, 2018:



Contract Balances	March 30, 2019			December 31, 2018			Change
Contract Accounts Receivable ⁽¹⁾	$	242.6		$	263.9		$	(21.3	)
Contract Assets	68.9			91.2			(22.3		)
Contract Liabilities - current	(84.0		)	(79.5		)	(4.5		)
Contract Liabilities - non-current ⁽²⁾	(2.0		)	(2.1		)	0.1
Net contract balance	$	225.5		$	273.5		$	(48.0	)

⁽¹⁾ Included in “Accounts receivable, net” within the accompanying condensed consolidated balance sheets.

⁽²⁾ Included in “Other long-term liabilities” within the accompanying condensed consolidated balance sheets.

The $48.0 decrease in our net contract balance from December 31, 2018 to March 30, 2019 was due primarily to cash payments received from customers during the period, partially offset by revenue recognized during the period.

During the first quarter of 2019, we recognized revenues of $27.4 related to our contract liabilities at December 31, 2018.

Performance Obligations

As of March 30, 2019, the aggregate amount allocated to remaining performance obligations was $81.7. We expect to recognize revenue on approximately 53% and 69% of remaining performance obligations over the next 12 and 24 months, respectively, with the remaining recognized thereafter.

Variable Consideration

Our recorded cumulative revenue associated with the large power projects in South Africa includes amounts of variable consideration related to claims and unapproved change orders. As indicated in Note 15, during February, March, and April of 2019, we received a number of claims from the prime contractors on these projects asserting various amounts of damages. In consideration of these recent claims (including the magnitude of the claims and claims in areas that had not been previously identified by the prime contractors), and in accordance with ASC 606, we analyzed the risk of a significant revenue reversal associated with the amount of variable consideration noted above. Based on such analysis, we reduced the amount of cumulative revenue associated with the variable consideration on the large power projects in South Africa by $17.5 during the three months ended March 30, 2019, as it was no longer probable that such amounts of revenue would not be reversed.

At March 30, 2019, our cumulative recognized revenue related to the variable consideration on the large power projects in South Africa, after the reduction noted above, totaled $19.9. We have recognized revenue associated with these claims, along with certain unapproved change orders, to the extent we have an enforceable right to the claim or change order, the amount can be reliably estimated, and it is probable that a significant reversal of the cumulative revenue recognized will not occur. While we believe these amounts are recoverable under the provisions of the related contracts, actual amounts of consideration ultimately received may differ from our estimates, which could have a material impact on our consolidated results of operations.
