Off-balance-sheet financing refers to any arrangement that lets a company raise capital or use an asset without recording the associated debt on its own balance sheet. The two most common structures are special purpose vehicles (SPVs) and synthetic leases — and both were central to some of the most infamous accounting failures in corporate history, most notably Enron.
Why Companies Use Off-Balance-Sheet Financing
Every dollar of reported debt pushes up a company's leverage ratios (like Debt/EBITDA), which can hurt its credit rating, raise its cost of borrowing, or trip covenants on existing loans. Off-balance-sheet financing lets a company access the economic benefit of debt — cash today, use of an asset — while keeping the liability off its reported balance sheet, making it look less leveraged than it actually is.
Special Purpose Vehicles (SPVs)
An SPV (also called a Special Purpose Entity, or a Variable Interest Entity/VIE under US GAAP) is a separate legal entity a company creates to isolate specific assets and liabilities — commonly to securitize receivables, hold real estate, or finance a specific project. Because the SPV is technically a separate legal entity, its debt historically didn't have to appear on the sponsoring company's balance sheet, as long as the sponsor didn't hold a majority equity stake.
That loophole is exactly what changed after Enron, which used hundreds of SPVs (like its "Raptor" entities) to move debt and underperforming assets off its books while retaining the economic risk. The accounting rules were rewritten (FIN 46/46(R), now codified as ASC 810) to introduce the Variable Interest Entity (VIE) model: an SPV must now be consolidated if the sponsor has the power to direct its most significant activities and absorbs the majority of its losses or benefits — the "primary beneficiary" test — regardless of how much equity it actually owns.
Synthetic Leases
A synthetic lease is a lease deliberately structured to be treated as an operating lease for accounting purposes (keeping the asset and its financing off the balance sheet) while being treated as a purchase for tax purposes (letting the lessee claim depreciation deductions). It's "synthetic" because the accounting treatment and the tax treatment intentionally diverge.
The giveaway that a synthetic lease is really a financing arrangement in economic substance is usually a bargain purchase option — the right to buy the asset at lease-end for a price well below its expected fair market value. That feature transfers substantially all the risks and rewards of ownership to the lessee, which is the same economic position as if the company had simply borrowed money to buy the asset outright.
Why This Matters for Analysis
A reported Debt/EBITDA ratio that ignores SPV debt and synthetic lease obligations can materially understate a company's true leverage. Analysts, lenders, and credit rating agencies routinely reclassify these arrangements back onto the balance sheet to get an accurate picture of financial risk. For a full worked example — including exactly how much a company's leverage ratio changes once these arrangements are reclassified — see our case study on Off-Balance-Sheet Financing: SPVs and Synthetic Leases.

Off-balance-sheet financing is closely related to lease accounting more broadly — see our case on IFRS 16: Lease Accounting for how the rules changed to bring most operating leases onto the balance sheet, and why synthetic leases were specifically designed to sidestep similar treatment.
