The good business is worth twice (20 percent ÷ 10 percent = 2 times) its assets, for example, 2 × $5 million = $10 million. This is because we get the same return from the long bond by investing twice as much. The bad business earning 5 percent on invested capital is worth half its capital (5 percent ÷ 10 percent = 0.5 times).

(And both have the same price-to-earnings (PE) multiple: 10 times.) Graham might
