Index, the Base Monthly Rental for calendar year 2025 and for each subsequent calendar year shall increase by no less than two percent (2%) nor more than four percent (4%) per year. If the Bureau of Labor Statistics discontinues publication of the C.P.I. Index, publishes the C.P.I. Index less frequently, or alters the C.P.I. Index in a material manner, then Lessor, in its sole discretion, may adopt a substitute index or procedure which reasonably reflects and monitors consumer prices.
