Restricted Cash

Restricted cash includes cash held by us that is unavailable for general use and is comprised of amounts advanced to us by certain equity method investees related to the construction of fixed assets where we serve as construction manager. The following table presents a reconciliation of cash and cash equivalents and restricted cash reported on our Condensed Consolidated Balance Sheets that sum to the total of the amounts shown on our Condensed Consolidated Statements of Cash Flows (in millions):

Property and Equipment

During the first quarter of 2021, we modified the useful lives of certain of our Pipeline and related facilities and Storage, terminal and rail facilities to useful lives of 10 to 50 years from useful lives of 10 to 70 years to reflect current expectations given our future operating and commercial outlook. These depreciable life adjustments will prospectively increase depreciation expense. For the three months ended March 31, 2021, these reductions increased depreciation expense by approximately $18 million, which resulted in a decrease to both basic and diluted net income per common unit of approximately $0.03 from what it would have been absent the change in useful lives.
