This Amendment No. 22 amends Items 3, 4, 5 and 7 as set forth below.

Item 3.	SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

	Funds for the purchase of the Common Shares were derived from the subscription proceeds from investors and the capital appreciation thereon and margin account borrowings made in the ordinary course of business. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the account, which may exist from time to time. Since other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Common Shares reported herein. A total of approximately $424,448,249 was paid to acquire the Common Shares reported herein.

Item 4.	PURPOSE OF TRANSACTION Item 4 is hereby amended and supplemented as follows: The Reporting Persons issued the investor presentation (the "Investor Presentation") attached hereto as Exhibit 8 to shareholders (such exhibit to be deemed incorporated by reference in its entirety into this Item 4) providing their views on the Issuer and its Board, including value-unlocking steps it believes the Issuer should take.

(b)	See rows (7) through (10) of the cover pages to this Schedule 13D/A for the number of Common Shares as to which each Reporting Person has the sole or shared power to vote or direct the vote and sole or shared power to dispose or to direct the disposition.
