(1) ROIC - Return on invested capital is calculated using the following GAAP financial measures: Income before interest expense and income taxes plus common stock dividends paid, divided by the average of the year’s beginning and ending long-term debt plus common equity. This measure is used to more precisely evaluate operational performance and management effectiveness.
(2) The times interest earned ratio measures the ability to satisfy annual interest costs.

Atmos Energy continues to anticipate earnings to be in the range of $1.95 - $2.05 per fully diluted share for the 2008 fiscal year
Assumptions include:• Contribution from natural gas marketing segment reflecting less
volatility in gas prices o Total expected gross margin contribution from the marketing segment in
the range of $90 million to $100 million, excluding any material mark-to-market impact
• Continued successful execution of rate strategy and collection efforts• Bad debt expense of no more than $15 million• Average annual short-term interest rate @ 6.5%• No material acquisitions
Consolidated Earnings Guidance – Fiscal 2008E
Note: Changes in these events or other circumstances that the company cannot currently anticipate could materially impact earnings, and could result in earnings for fiscal 2008 significantly above or below this outlook.

Nonregulated OperationsAtmos Energy Marketing
We commercially manage our storage assets by capturing arbitrage value through optimization strategies that create embedded (forward) value in the portfolio. We financially report the transactions for external reporting purposes in accordance with generally accepted accounting principles (“GAAP”).
GAAP Reported Value is the period to period net change in fair value of the portfolio reported in the income statement that results from the process of marking to market the physical storage volumes and corresponding financial instruments in an interim period.
Economic Value is the period to period forward margin of our storage portfolio that results from the process of calculating our weighted average cost of inventory (WACOG), and our weighted average sales price of our forward financials (WASP), then multiplying the difference times inventory volumes. This margin will be realized in cash when the hedged transaction is executed or when financials are settled and then reset to stay hedged against physical volumes.
• Economic Value represents the “forward” economic margin of the transactions, while GAAP reported results reflect that portion of our “forward” margin that has been recorded in the income statement.
• Volatility in earnings includes the impact of the accounting treatment of our storage portfolio in accordance with GAAP and is reflective of relatively high price volatility of the prompt month, and the relatively low volatility of the offsetting forward months.
