Two concerns are central. First, one partner's goods may remain separately identifiable, so a true common pool may not form. Second, when the partnership ends, the original goods may already have been sold or their value may have changed.
These concerns explain why different schools set different conditions for non-cash capital.
This distinction will be used repeatedly in later applications. Before calculating profit or designing an exit, first identify who owns what, who works in the business and which rule governs genuine loss.
