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 $(96.8) million, $11.1 million and $43.7 million for 2018, 2017, and 2016 respectively.

We accrued $11.8 million related to the dividends declared in 2018 that will be paid in 2019. At December 31, 2017 and 2016, we had accrued dividends of $12.1 million and $96.3 million which were paid in 2018 and 2017, respectively.

On October 24, 2017, a lease financing transaction was completed with respect to an articulated tug and barge unit that is being used to transport ammonia for our operations. As described in more detail in Note 23, we had provided bridge loans to a consolidated affiliate for construction of the unit, and that entity also received construction loans from a joint venture in which we hold a 50% interest. Following the application of proceeds from the transaction, all outstanding construction loans to the joint venture entity, together with accrued interest, were repaid.
