This communication may contain forward-looking statements. Forward-looking statements include, without limitation, statements regarding the estimated future financial performance and financial position of the Company. Future results are not possible to predict. Opinions and estimates offered in this communication constitute the Company’s judgment and are subject to change without notice, as are statements about market trends, which are based on current market conditions. This communication contains forward-looking statements, including without limitation, forward-looking statements that represent opinions, expectations, beliefs, intentions, estimates or strategies regarding the future of the Company and its affiliates, which may not be realized.

All forward-looking statements are based on estimates and assumptions that are inherently uncertain and that could cause actual results to differ materially from expected results.
