The Company primarily has operating leases for corporate office space and certain equipment. Operating lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. When readily available, the Company uses the implicit rate in determining the present value of the lease payments. When leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on information available at the commencement of the lease, including the lease term. Because the implicit rate in each lease is not available, the Company used its incremental borrowing rate to determine the present value of lease payments. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Variable components of the lease payments, such as utilities and maintenance, are expensed as incurred and are not included in determining the present value.

The recorded value is adjusted based on the Company's proportionate share of the businesses net income and is recorded three months in arrears. See note 8 for additional disclosures.
