What the numbers say

On the four Ms, Marsh & McLennan Companies, Inc. earns 91 for management and 96 for moat. The management score rests on a return on invested capital of 12.1% and a gross margin of 42.3% — figures that describe a business turning capital into profit efficiently. Debt sits at 1.42x equity.

Three independent anchors set the price worth paying. Growth is modelled at 9.4% a year, the rate measured from the filings. The exit multiple assumed is 18.8x. That produces an intrinsic value of $93.20, a 10-CAP price of $100.42 and a payback time price of $122.88, with the value zone set at the highest of the three, $122.88. Today's price of $171.85 is 40% above it.

The operating figures describe a business performing at a high level; the price asks for that performance to continue and then some. A margin of safety score of 27 is the measure of how little room that leaves for being wrong.
