Acquiring or constructing property, plant and equipment by incurring a liability does not result in a cash outflow for us until the liability is paid. In the period the liability is incurred, the change in operating accounts payable on the Consolidated Statements of Cash Flows is adjusted by such amount. In the period the liability is paid, the amount is reflected as a cash outflow from investing activities. The applicable net change in operating accounts payable that was classified to investing activities on the Consolidated Statements of Cash Flows was $(29.8) million, $63.2 million and $(96.8) million for 2020, 2019 and 2018 respectively.

We accrued $20.4 million related to the dividends declared in 2020 that will be paid in 2021. At December 31, 2019 and 2018, we had accrued dividends of $20.0 million and $11.8 million which were paid in 2020 and 2019, respectively.

We had non-cash investing and financing transactions related to right-of-use assets obtained in exchange for lease obligations assets under finance leases in 2020 of $36.4 million.
