How often can Big Blue Swim School implement an Annual Increase to fixed fees?

We have the right to increase any fixed fee, fixed payment, or fixed amount (i.e., not stated as a percentage) under the Franchise Agreement based on changes in the Index (defined below) ("Annual Increase"). An Annual Increase may occur only once per calendar year and may not exceed the corresponding cumulative increase in the Index since the Franchise Agreement's effective date or, as the case may be, since the date on which the last Annual Increase became effective for the particular fixed fee, payment, or amount being increased. All Annual Increases will be made at the same time during the calendar year. "Index" refers to the Consumer Price Index for All Urban Consumers (CPI-U) for the U.S. City Average, All Items (1982 – 1984 = 100), not seasonally adjusted, as published by the United States Department of Labor, Bureau of Labor Statistics, or in a successor index. We also have the right—if any fixed fee, payment, or amount due from you under the Franchise Agreement encompasses any third-party charges we collect from you on a pass-through basis (i.e., for ultimate payment to the third party)—to increase the fixed fee, payment, or amount beyond the Annual Increase to reflect increases in the third party's charges to us.
