| 5. | We note your response to comment 13 in our letter dated May 13, 2011. Please revise to quantify the Enterprise Values, 2010 and 2011 Adjusted EBITDA, transaction values, and unlevered after-tax cash flow forecasts. |
In response to the Staff’s comment with respect to quantifying enterprise values, transaction values and unlevered after-tax cash flow forecasts, the disclosure on pages 41, 46 and 47 of the Amendment No. 2 has been revised. With respect to 2010 and 2011 adjusted EBITDA amounts, however, additional disclosure has not been included, as per our recent discussions with the Staff. We do not believe the inclusion of such adjusted EBITDA amounts is material to shareholders. The important data for investors relates to the multiples, enterprise values and transaction values, all of which are included in the proxy statement. With the inclusion of the enterprise values and the transaction values an investor can perform simple arithmetic to calculate the approximate amount of adjusted EBITDA (where available).
