Abstract: | Electric utilities differ in their accounting procedures. By regulatory commission directive some use normalization and some use flow through to arrive at their earnings figures. Because regulation is on an allowed return on investment standard these reported earnings are relevant for stock valuation. Any variation in price/earnings ratios between flow through and normalizing companies therefore must be explained by differences in risk to equity investors, differences in investment opportunities, or market inefficiency involving erroneous restatement of earnings. Empirical work demonstrates that there is a difference in price/earnings ratios. Firms that normalize enjoy a premium. The evidence also indicates that the premium is not explained by risk difference. Because the perverse form of market inefficiency required as an explanation seems unlikely, the most reasonable conclusion is that the premium relates to investment opportunities associated with regulatory climate. If so it promises no excess return to stock buyers because it is already impounded in stock price. |
