Therefore, we estimate our incremental borrowing rate, which is defined as the interest rate we would pay to borrow on a collateralized basis, considering such factors as length of lease term and the risks of the economic environment in which the leased asset operates. As of December 31, 2021, 2020 and 2019, our lease agreements had the following remaining lease term and discount rates:


	2021	2020	2019
