Fortnightly 40 Index

Our annual survey of power and gas company performance relies on a modified DuPont model, based on its 89 year-old namesake approach for calculating shareholder value in asset-intensive industries. In 2008 we tweaked the model—which originally was developed in 1919 by a finance executive at E.I. du Pont de Nemours & Co.—to measure growth on a long-term, sustainable basis (See sidebar “F40 Model Characteristics”).

The Fortnightly 40 model combines several common measures of financial performance—profitability, dividend yield, cash flow, return on equity (ROE) and return on assets (ROA)—together with a sustainable growth-rate calculation, to produce an overall picture of a company’s value and long-term prospects. To avoid the pitfalls of short-term fluctuations, the model evaluates four years of results for each company. (This represents a change from 2008 and previous F40 rankings, which considered three years of financial results.)

The universe for the ranking—which this year numbers 82 companies—includes publicly traded, U.S.-based companies with major assets in energy production, transportation and retail delivery, and positive shareholder equity value for the past four years. Pure-play mining and exploration & production companies are excluded, but a few pure-play merchant power generation companies are included in the sample.–MTB

F40 Model Characteristics

Time Frame: 4-year average

Sample: 80 largest U.S.-based investor-owned power and gas companies, with assets in power generation or electricity and gas transmission and distribution.

Components:

1. Profitability= Margin = Income from Continuing Operations/Total Revenues.

2. Dividend Yield= Annual Declared Dividends/Year-End Stock Price.

3. Free Cash Flow= Operating Cash Flow from Continuing Operations – Capital Expenditures.

4. DuPont ROE Five-Ratio Model:

a. Earnings after taxes (EAT) = Income from Continuing Operations after Taxes;

b. Earnings before taxes (EBT) = Income from Continuing Operations + Income Taxes;

c. Earnings before interest and taxes = Income from Continuing Operations before Income Taxes and Interest;

d. Revenues = Total Revenues;

e. Assets = Total Assets; and

f. Equity = Total Common Shareholders Equity.

5. DuPont ROE= (EAT/EBT)×(EBT/EBIT)×(EBIT/Revenues)×(Revenues/Assets)×(Assets/Equity).

6. DuPont ROA= (EAT/Revenue)×(Revenue/Assets)

7. Sustainable Growth= DuPont ROE×(1–Dividend Payout Ratio).

8. Fortnightly Index9. Companies excluded from the FY2011 survey due to M&A activity: Allegheny Energy, DPL, and Nicor.
