There is probably a Private Equity Secret Handbook that describes the ways at which you can make things look like something is happening in the company when in reality it is just smoke and mirrors. The claims of efficient organizational changes and increased sales probably needs a second party to confirm the claims to see if they are true.
Time will tell. I am sure Warburg Pincus does not want to hold onto this company that much longer. Two years for an IPO is a long time for a company like WP that does not like to go beyond four years for flipping their companies and they have owned B&L for at least four years.
