On aligning investor view to management view...

While it may seem common sense to align management view to investor view, it holds more true for public companies than private.  Probably a function of the fact that GAAP requires segment reporting to align - how you manage the business is how you report it externally.  But Jim gave a practical perspective as well...

While you could lean on GAAP requirements to drive the alignment, it is also good practice to align the views.  This enables leaders to answer investor questions with more authority and not have to create a map between the internal management view, and external investor view.  And even if there is some misalignment, because there might have to be, it is sound practice to have very limited disparity.  

In a company where a common friend worked, there was misalignment between internal management view and external investor view, and it resulted in only the accountants (and some leaders) caring for the investor view.  During earnings calls or investor day meetings when business leaders met investors, answering specific questions became extremely hard - a situation you want to avoid as a CFO.
