Please disclose how you account for (a) step rent provisions and escalation clauses and (b) capital improvement funding and other lease concessions, which may be present in your leases. Paragraph 19.b. of SFAS 13 discusses how rent should be reported as income over the lease term as it becomes receivable. However, if the rentals vary from a straight-line basis, the income shall be recognized on a straight-line basis unless another basis is more representative of the time pattern in which the benefit from the leased property is diminished. In addition, paragraph 5.n. of SFAS 13, as amended by SFAS 29, discusses how lease revenues that depend on an existing index or rate, such as the consumer price index or the prime interest rate, should also be included in your minimum lease revenues. If, as we assume, they are taken into account in computing your minimum lease revenues, the note should so state. If our assumption is incorrect, please tell us how your accounting complies with SFAS 13 and FTB 88-1. Long-Lived Assets, page 13 6.
