You are the managing partner of a medium-size CPA firm with several publicly traded clients. One of your partners, John DeFries, has served as lead partner for the audit engagement of Rousch Industries, a publicly traded client, for the last five years. He has just gotten the word that he will be replaced in that capacity by another partner beginning with next year's audit and is quite upset over the situation. He is emailed you arguing that he is invested years getting to know Rousch's business operations and is therefore the best qualified partner to lead the audit. He feels he is being penalized for some reason he does not understand. Write an email to Mr. DeFries explaining the requirements of the Sarbanes-Oxley act and the SEC regarding audit partner rotation and assuring him that he is not being penalized for anything
