Leases

Our leases consist primarily of office and manufacturing and construction equipment. All of our future lease obligations are related to non-cancelable operating leases. The decrease of our lease portfolio relates to the wind down of our Canadian facility leases. The following table provides a summary of lease cost components for the three and nine months ended June 30, 2023 and 2022, respectively (in thousands):

	Three months ended June 30,				Nine months ended June 30,

Leases with initial terms of twelve months or less are not recorded in our Condensed Consolidated Balance Sheets.
