The idea behind Marmon, PCP, and Alleghany - is that all three could do a lot of bolt on deals ... in different industries ... which are immaterial to Berkshire HQ - but overtime could be sizable to the organization. The results are still out on this - but frankly, as mini-serial acquires these have been so-so. Marmon was a solid double, PCP is mixed so far ... and Alleghany is really interesting.
