If any such risks or uncertainties materialize or if any of the assumptions prove incorrect, the Company’s results could differ materially from the results expressed or implied by the forward-looking statements the Company makes.
The risks and uncertainties referred to above include - but are not limited to - risks associated with: adjustments to our preliminary estimates for the financial results of the first quarter; issues encountered in the completion of the quarterly review; and general economic conditions.
Further information on these and other factors that could affect the Company’s financial results is included in filings it makes with the Securities and Exchange Commission from time to time, including the section entitled “Risk Factors” in the Company’s most recent Form 10-K filed with the SEC.
