This pro forma information utilizes certain estimates, is presented for illustrative purposes only and may not be indicative of the results of operation that would have actually occurred. In addition, future results may vary significantly from the results reflected in the pro forma information. The unaudited pro forma financial information does not reflect the impact of future events that may occur after the acquisition, such as anticipated cost savings from operating synergies.
