Summary of Significant Accounting Policies

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):


	September 30, 2021		December 31, 2020
Cash and cash equivalents	$	191	$	22
Restricted cash	3		38
Total cash and cash equivalents and restricted cash	$	194	$	60

Property and Equipment

During the first quarter of 2021, we modified the useful lives of certain of our Pipelines 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 and nine months ended September 30, 2021, these reductions in useful lives increased depreciation expense by approximately $18 million and $54 million, respectively, which resulted in a decrease to both basic and diluted net income per common unit of approximately $0.02 for the three months ended September 30, 2021 and approximately $0.07 for the nine months ended September 30, 2021 from what these amounts would have been absent the change in useful lives.

Recent Accounting Pronouncements

Except as discussed below and in our 2020 Annual Report on Form 10-K, there have been no new accounting pronouncements that have become effective or have been issued during the nine months ended September 30, 2021 that are of significance or potential significance to us.

Accounting Standards Updates Adopted During the Period

We adopted the following ASUs during the period:

•ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. See Note 2 to our Consolidated Financial Statements included in Part IV of our 2020 Annual Report on Form 10-K for additional information regarding this ASU. We adopted this ASU effective January 1, 2021 and our adoption did not have a material impact on our financial position, results of operations or cash flows.

•ASU 2021-05, Leases (Topic 842): Lessors - Certain Leases with Variable Lease Payments. Issued by the FASB in July 2021, ASU 2021-05 modifies the lease classification requirements for lessors in Topic 842, which we adopted on the effective date of January 1, 2019. The amendments require lessors to classify and account for a lease with variable lease payments that do not depend on a reference index or a rate as an operating lease at lease commencement if another classification (i.e., sales-type or direct financing) would result in the recognition of a day-one loss. For entities that have adopted Topic 842, the guidance is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2021, with early adoption permitted. We have elected to early adopt the guidance on a prospective basis as of July 1, 2021. Our adoption did not have a material impact on our financial position, results of operations or cash flows.
