annum. Therefore, any dividends declared after July 15, 2030 may vary from period to period and could be more or less than the fixed rate for the initial five-year period. We have no control over a number of factors that may affect market interest
rates, including, for example, geopolitical conditions and economic, financial, political, regulatory, judicial or other events that affect the markets generally and that are important in determining the existence, magnitude, and longevity of market
rate risk.
