What is the difference between operating lease and financial lease?

A finance lease is a form of financing that transfers substantially all the risks and rewards incidental to ownership over a leased asset from the lessor to the lessee. By signing the contract and delivering the leased asset, the lessor transfers economic ownership over the leased asset, while legal ownership is transferred only upon the expiration of lease, on payment of the final instalment. In a finance lease, the lessee uses the leased asset for most of its lifecycle, as with loans.

An operating lease is a lease whereby all the risks and rewards incidental to ownership over the leased asset remain with the lessor. In this case, the lessor retains the economic and legal ownership over the leased asset, while the lessee has only right of use. Upon the expiration of contract, the leased asset is returned to the lessor. Under an operating lease, the lessee uses the leased asset for less than its useful life.
