Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, the following: interest rate risk, including the effects of changes in interest rates;

our ability to implement our growth strategy and manage costs effectively; the composition of our senior leadership team and our ability to attract and retain key personnel; talent and labor shortages and employee turnover;
