Off-balance sheet (OBS) financing is an accounting practice whereby a company does not include a liability on its balance sheet. It is used to impact a company’s level of debt and liability.
Lastly, OBS financing can often create liquidity for a company. For example, if a company uses an operating lease, capital is not tied up in buying the equipment
In addition to debt ratios, other OBS financing situations include operating leases and sale-leaseback impact liquidity ratios.
OBS financing arrangements are discretionary, and although they are allowable under accounting standards, some rules govern how they can be used.
