Leases [Abstract] |
Leases | Leases We have finance and operating leases through which we obtain the right to use equipment and facilities in our manufacturing operations and R&D activities as well as office space and other facilities used in our SG&A functions. Our finance leases consist primarily of gas or other supply agreements that are deemed to contain embedded leases in which we effectively control the underlying gas plants or other assets used to fulfill the supply agreements. Our operating leases consist primarily of offices, other facilities, and land used in SG&A, R&D, and certain of our manufacturing operations. Certain of our operating leases include one or more options to extend the lease term for periods from one year to 10 years for real estate and one year to 30 years for land. Certain supply or service agreements require us to exercise significant judgment to determine whether the agreement contains a lease of a right-of-use asset. Our assessment includes determining whether we or the supplier control the assets used to fulfill the supply or service agreement by identifying whether we or the supplier have the right to change the type, quantity, timing, or location of the output of the assets. Our gas supply arrangements generally are deemed to contain a lease because we have the right to substantially all of the output of the assets used to produce the supply and we have the right to change the quantity and timing of the output of those assets. In determining the lease term, we assess whether we are reasonably certain to exercise options to renew or terminate a lease, and when or whether we would exercise an option to purchase the right-of-use asset. Measuring the present value of the initial lease liability requires judgment to determine the discount rate, which we base on interest rates for borrowings with similar terms and collateral issued by entities with credit ratings similar to ours. Operating lease costs include short-term and variable lease expenses. Short-term, variable leases, and sublease income are not material for the periods presented. The components of lease expense are presented below:

Finance lease cost |  |
Amortization of right-of-use asset | $ | 69 |  | $ | 140 |

2027 and thereafter | 454 |  | 372 |
Less imputed interest | (130) |  | (108) |
| $ | 803 |  | $ | 559 |
The table above excludes any lease liabilities for leases that have been executed but have not yet commenced. As of September 2, 2021, we had such lease liabilities relating to (1) operating lease payment obligations of $147 million for the initial 10-year lease term for a building, which may, at our election, be terminated after 3 years or extended for an additional 10 years, and (2) finance lease obligations of $553 million over a weighted-average period of 15 years for gas supply arrangements deemed to contain embedded leases. We will recognize right-of-use assets and associated lease liabilities at the time such assets become available for our use.
