Certain of our operating leases include one or more options to extend the lease term for periods from two to five years. In determining the present value of our operating lease liabilities, we have assumed we will not extend any lease terms.

The table above excludes lease liabilities for leases that have been executed but not yet commenced. As of November 26, 2021, we had such lease commitments relating to operating lease payment obligations of $51.8 million for a building lease with a term of 16 years. We will recognize a right-of-use asset and an associated lease liability at the time such asset becomes available for our use. Such lease is currently expected to commence in the second half of calendar 2022.
