The leases cannot generally be extended or terminated at the customer’s discretion. However, upon the mutual agreement of the parties, the leases can be early terminated after three months. Rental charges are computed based on a time rate of machine’s type and rental period. The leases of mining equipment meet the classification of operating leases, and revenues from operating leases are recognized on a straight-line basis over the contract terms. The Company ceased leasing mining equipment in the second quarter of 2021.</p>
