Effective January 1, 2019, we adopted Topic 842. We recognized $91.9 million and $112.9 million of existing operating leases as right of use assets and lease liabilities effective January 1, 2019.

The right of use assets and lease liabilities included in our balance sheet are as follows:

Long-term operating lease liabilities included in other non-current liabilities	68.4		71.2
Total operating lease liabilities	$	91.7	$	93.6

We recognized $12.9 million for both right of use assets and lease liabilities related to new operating leases for the year ended December 31, 2020.

The operating lease cost, supplemental cash flow and other information, and maturity analysis for leases is as follows:

We recorded impairment charge of $14.8 million for the year ended December 31, 2020, primarily as a result of our decision to shift our workforce model to working remotely in the United States and certain international markets.

Cash paid for operating leases is included in operating cash flows and was $28.1 million, $23.7 million and $5.9 million for the year ended December 31, 2020 (Successor), the period from January 1, 2019 to December 31, 2019 (Successor) and for the period from January 1, 2019 to February 7, 2019 (Predecessor), respectively.

Rent expense under operating leases (cancelable and non-cancelable) was $32.9 million for the year ended 2018 (Predecessor).
