Short-term leases (those with terms of 12 months or less) are not capitalized but are expensed on a straight-line basis over the lease term. The majority of our short-term leases relate to equipment used on construction projects. These leases are entered into at periodic rental rates for an unspecified duration and typically have a termination for convenience provision.

As of September 30, 2022, the weighted-average remaining term of the Company’s operating leases was 8.5 years, and the weighted-average discount rate was 3.19%. As of September 30, 2022, the lease liability was equal to the present value of the remaining lease payments, discounted using the incremental borrowing rate on the Company’s secured debt using a single maturity discount rate, as such rate is not materially different from the discount rate applied to each of the leases in the portfolio.
