Note 3. Leases

We evaluate contracts for leasing arrangements at inception. We lease office space, equipment, and vehicles that have non-cancelable lease terms. Leases with a term of 12 months or less are not recorded on our balance sheet. The table below reflects our operating lease assets and liabilities, which primarily consists of our office leases, and finance lease assets and liabilities:

Operating leases
Operating lease right-of-use assets	$	37,913

Operating lease liabilities - current	$	7,070
Operating lease liabilities - long-term	47,056
Total operating lease liabilities	$	54,126

Finance leases

Other property and equipment, net	$	1,861

Current maturities of long-term debt	$	1,671
Long-term debt, net of current portion	348
Total finance lease liabilities	$	2,019

The majority of our leases contain renewal options, typically exercisable at our sole discretion. We record right-of-use assets and liabilities based on the present value of lease payments over the initial lease term, unless the option to extend the lease is reasonably certain, and utilize our incremental borrowing rate based on information available at the lease commencement date. The following weighted average remaining lease terms and discount rates related to our outstanding leases:



	March 31,
	2019
Weighted Average Remaining Lease Term
Operating leases	6.3 years
Finance leases	1.2 years

Weighted Average Discount Rate
Operating leases	6.8	%
Finance leases	2.5	%

Lease costs for operating leases or leases with a term of 12 months or less are recognized on a straight-line basis over the lease term. For finance leases, interest on the lease liability and the amortization of the right-of-use asset are recognized separately, with the depreciable life reflective of the expected lease term. We have subleased part of the office space included in our operating leases for which we receive rental payments. The following table summarizes the components of lease costs and sublease income:
