Disaggregation of Revenue [Table Text Block]

In the following table, revenue is disaggregated by major lines of goods and services and timing of transfer of goods and services. We have determined that these categories depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. The table below also includes a reconciliation of the disaggregated revenue with our reportable segments.

The opening and closing balances of our receivables from contracts with customers and our current and long-term contract assets and contract liabilities are as follows:

Revenue recognized in the period from:
Amounts included in contract liability at the beginning of the period	$	7.5
Performance obligations satisfied in previous periods	$	5.9

The differences between the opening and closing balances of our contract assets and contract liabilities primarily result from the timing differences between our performance and the customer’s payment, as well as changes in the estimated transaction price related to variable consideration that was constrained for performance obligations satisfied in previous periods. Other significant changes include contract assets of $8.3 million reclassified to receivables.
