If the lessee rents the asset for say $10,000 over 5 years and then there is an option to continue the rent for an additional 3 years (secondary period) for $100 (lower than the market rental), then we have a finance lease as in substance we have ownership.
If the lease is stopped/terminated (called) during the lease period and the losses from the termination are paid for (born by) the lessee then there is a finance lease.
