How much would you pay for a $298 billion perpetual bond with an 8.5% coupon and $66 billion of additional cash? While this seems like an odd question, I would argue it is the one you're trying to answer when choosing to invest, or not invest, in Berkshire Hathaway (BRK.B,BRK.A). No, Berkshire common stock is not a bond; however, as I will try to demonstrate, while Berkshire's stated GAAP earnings are volatile, its underlying return on shareholders' equity is highly consistent, not entirely dissimilar to a bond coupon. This analysis will disaggregate Berkshire's constituent assets and liabilities in its various business segments and the earnings attributable to those segments. Doing so will allow us to uncover what I will term a "steady-state" return on equity. With that return in hand, we can then determine the "yield" and subsequent value to assign our "bond."
