Is Compass bait for Deloitte to acquire TPI or does TPI parent have bigger plans?

Following the confirmation about KPMG taking over Equaterra talk of TPI being swallowed by Deloitte has re-emerged. Well that's amongst the people I speak to anyway

Sources have told me that the benchmarking capabilities of Compass, which TPI's parent recently acquired, make TPI a very attractive one stop consultancy. They also say that TPI parent Information Services Group (ISG) is an investment vehicle, which would probably look to sell TPI/Compass on.

For instance the Compass acquisition could have been made to make TPI more attractive to Deloitte. All just speculation.

But an industry source told me this is not the case. "ISG sees itself as a company with a portfolio of businesses that provide advisory services using fact based analysis as the foundation."
