LEASE OBLIGATIONS

12 Months Ended

NOTE 12 - LEASE OBLIGATIONS

Our operating leases consist primarily of leases for land, office space, rail cars and storage tanks. Our finance leases consist primarily of mining equipment, an on-site coke battery and rail cars. We use our incremental borrowing rate as the discount rate to determine the present value of the lease payments, as our leases do not have readily determinable implicit discount rates. Our incremental borrowing rate is the rate of interest that we would have to borrow on a collateralized basis over a similar term and amount in a similar economic environment to pay our lease obligations. We determine the incremental borrowing rates for our leases by adjusting the local risk-free interest rate with a credit risk premium corresponding to our credit rating. From time to time, we may enter into arrangements for the construction or purchase of an asset and then enter into a financing arrangement to lease the asset. We recognize leased assets and liabilities under these arrangements when we obtain control of the asset.
