BOSTON/NEW YORK Nov 5 (Reuters) - Billionaire investor Bill Ackman expressed confidence in Valeant Pharmaceuticals International Inc's chief executive on Thursday as shares in the drugmaker fell as much as 20 percent to their lowest level since 2013 on concerns over its business practices.

Valeant has denied the allegations, but has not allayed investor concerns as new reports surface of questionable billing practices at Philidor.
One trigger for Thursday's selling was a Wall Street Journal report that Ackman had told a Valeant board member that Pearson may have to go. Later in the day, Ackman expressed confidence in the CEO's leadership and willingness to take steps in the best interest of investors.
"You are one of the most shareholder-oriented CEOs I know," Ackman wrote to Pearson in an email seen by Reuters. "You have assured me that you and the rest of the board are considering any and all alternatives that would benefit shareholders and other stakeholders."
Ackman's Pershing Square Capital Management and its investors have lost roughly $2.3 billion since taking a 6 percent stake in Valeant early in the year. The size of Ackman's fund has shrunk to roughly $14.5 billion from $20 billion earlier in the year as Valeant, his biggest bet, has soured.
