The Company has made certain assumptions and judgments when applying ASC 842, the Company elected not to recognize right-of-use assets and lease liabilities for short-term leases (lease terms of twelve months or less).

Operating lease arrangements primarily consist of office, warehouse and test house leases expiring during different years through 2025. The facility leases have original lease terms of approximately one to five years and may contain options to extend up to 5 years and/or terminate early. Options to extend are included in leased right-of-use assets and lease liabilities in the consolidated balance sheet when we are reasonably certain to renew a lease. Since the implicit rate of such leases is unknown and we may not be reasonably certain to renew leases, the Company has elected to apply a collateralized incremental borrowing rate to facility leases on the original lease term in calculating the present value of future lease payments. As of September 30, 2023 and December 31, 2022, the weighted average discount rate for operating leases was 3.8% and 3.9%, respectively and the weighted average remaining lease term for operating leases was 2.0 years and 2.7 years, respectively.

The Company has entered into various short-term operating leases, primarily for test houses and office equipment with initial terms of 12 months or less. These short-term leases are not recorded on the Company's consolidated balance sheet and the related short-term lease expense was $23,000 and $21,000, for the three months ended September 30, 2023 and 2022, respectively. Total operating lease cost was $0.3 million and $0.2 million for the three months ended September 30, 2023 and 2022, respectively, and $0.8 million for each of the nine months ended September 30, 2023 and 2022, respectively.
