California Code, Financial Code - FIN § 7703

(a) A “net lease” is a lease under which the association will not, directly or indirectly, provide or be obligated to provide for:

(b) A “full-payout” lease is one from which the lessor can reasonably expect to realize a return of its full investment in the leased property, plus the estimated cost of financing the property over the term of the lease, from rentals, estimated tax benefits, and the estimated residual value of the property at the expiration of the initial term of the lease; provided that no more than 20 percent of the return may be realized from the residual value of the property at the expiration of the initial term of the lease. Both the estimated residual value of the property and that portion of the estimated residual value relied upon by the lessor to satisfy the requirements of a full-payout lease must be reasonable in light of the nature of the leased property and all relevant circumstances so that realization of the lessor's full investment plus the cost of financing the property depends primarily on the creditworthiness of the lessee, and not on the residual market value of the leased property. The maximum term of a full-payout lease shall be 40 years.
