Equipment Lease with Security Agreement and Purchase Option is a type of finance agreement that allows a business to acquire a piece of equipment for their use. It is a three-way agreement between the equipment lessor, the equipment lessee, and a third-party lender. The lessor provides the equipment to the lessee, who pays the lender a fee for the privilege of leasing the equipment. The lease also contains a security agreement, which grants the lender a lien on the equipment, and a purchase option, which gives the lessee the right to purchase the equipment at the end of the lease term. There are two main types of Equipment Lease with Security Agreement and Purchase Option: Capital Lease and Operating Lease. A capital lease is a lease that is treated as a purchase by the lessee for tax and accounting purposes. An operating lease, on the other hand, is a lease that is treated as a rental for tax and accounting purposes.
