Our leases consist of office facilities under noncancelable operating lease arrangements that expire at various dates through 2033. Our leases do not contain any material (i) non-lease components, (ii) variable lease costs, (iii) short-term lease expenses, (iv) residual value guarantees or (v) material restrictive covenants.

For the years ended December 31, 2022, 2021 and 2020, lease expense of $6.2 million, $5.6 million and $7.0 million, respectively, was included in costs and operating expenses in the consolidated statements of operations.

For the years ended December 31, 2022, 2021 and 2020, cash paid for amounts affecting the measurement of our operating lease liabilities included in cash flows from operating activities was $6.4 million, $6.2 million (excluding $1.6 million of cash collected from lease incentive receivable), and $3.0 million (excluding $5.7 million of cash collected from lease incentive receivable), respectively.

As of December 31, 2022 and 2021, the weighted average remaining lease term was 8.7 years and 8.5 years, respectively, and the weighted average discount rate was 6.9% and 5.8%, respectively.

In May 2021, we entered into a noncancelable lease agreement with a third-party to lease additional office space that is adjacent to and expands our existing corporate headquarters in Santa Monica, California. The lease commenced on October 1, 2022 upon our access to the leased premises, and we recognized an operating lease right-of-use asset and lease liability of $20.2 million as of that date. Given changes in our property needs since the date we executed the lease, we no longer plan to occupy this premise and are seeking to sublease the property. As a result, we recognized a loss of $1.3 million during 2022 within general and administrative expenses for the disposal of capitalized costs related to architectural design and other professional services incurred. We also recognized an impairment loss of $11.3 million during 2022 within general and administrative expenses to reduce the carrying value of the operating lease right-of-use asset to its estimated fair value as rental rates have declined since the date the lease was executed. The estimated fair value was determined by using a discounted cash flow method which is a non-recurring fair value measurement based on Level 3 inputs. Key inputs used in this estimate include projected sublease income and a discount rate which incorporate the risk of achievement associated with the forecast. Significant changes in the projected sublease income or discount rate would result in a significantly higher or lower fair value measurement. The estimated operating lease payments included in the table above for 2023 and 2024

have been reduced by lease incentives for leasehold improvements of $3.1 million each year related to this additional office space.
