An equipment trust certificate allows a company to obtain possession and use of an asset by paying for it over time through debt financing. If payments are made, title is transferred to the borrower, but if payments are defaulted on, the lender can repossess the asset. Originally used to finance railway equipment, equipment trust certificates now mainly finance aircraft and shipping containers. They provide tax benefits to borrowers by avoiding property taxes on used assets, and protect lenders by allowing repossession of the asset if payments are defaulted on.
