Leases

Our leases consist primarily of office and manufacturing space, construction equipment and office equipment. All of our future lease obligations are related to non-cancelable operating leases. The most significant portion of our lease portfolio relates to leases of office and manufacturing facilities in Canada which we no longer occupy. We currently sublease the majority of these Canadian facilities. The following table provides a summary of lease cost components for the three months ended December 31, 2019 (in thousands):



Lease Cost	Three months ended December 31, 2019

Operating lease cost	$	628
Less: sublease income	(79		)
Variable lease cost⁽¹⁾	94
Short-term lease cost⁽²⁾	190
Total lease cost	$	833

⁽¹⁾ Variable lease cost represents common area maintenance charges related to our Canadian office space leases.

⁽²⁾ Short-term lease cost includes leases and rentals with initial terms of one year or less.

We recognize operating lease assets and operating lease liabilities representing the present value of the remaining lease payments for leases with initial terms greater than twelve months. Leases with initial terms of twelve months or less are not recorded in our Condensed Consolidated Balance Sheets. Our operating lease assets have been reduced by a lease accrual of $0.8 million related to certain unused facility leases in Canada. The following table provides a summary of the operating lease assets and operating lease liabilities included in our Condensed Consolidated Balance Sheets as of December 31, 2019 (in thousands):
