The moving averages need consecutive days and are drawn from the daily part. P/E is the close over the trailing four quarters' EPS as filed at each filing date, on the current share count; the dashed line is the median over the range shown.

* The fourth quarter is the full year less the first three quarters, because the company files the year and not the quarter on its own. Money is in $ million as the company files it, or in $ billion by the switch above the tables; per share figures and the share count are as they are. Free cash flow is operating cash flow less capital expenditure; the effective tax rate is income tax over pre-tax income; margins are the line over revenue. Gross profit is revenue less cost of revenue, and operating income is revenue less the company's own total costs, where the statement does not print those lines. Cash flow lines filed year to date are the difference between two filings. Shares outstanding are at the period end where the balance sheet tags them, otherwise the count on the filing's cover page. A derived fourth-quarter EPS is left blank when a split in the year makes the arithmetic meaningless.Income statement (profit and loss), 12 fiscal years and the trailing twelve months
Play it forward: change any box and its column follows; every box opens at the company's own record, shown under the row's name, and says when you set it outside every year in the table.

Each column runs from the last twelve months as filed to the year chosen in its heading, at a yearly rate. Sales growth starts at the company's own five-year rate and eases a third of the way each year toward the median of the 65 peers in Utilities (6.9% a year), because a rate far from the rest rarely lasts. Before you open a year, the strip reads today's price backwards: the yearly sales growth that brings EPS, at the company's own margins, tax and share count, to today's price at the median P/E of the 66 peers in Utilities (20.2). Low, middle, high opens three columns for one year: the low and high cases take the company's own weaker and stronger years in the table (the lower and upper quarter of its yearly sales growth and operating margin) and the lower and higher of today's P/E and its peers'; the middle is the boxes as they open. Net income keeps the share that went to minority holders; EPS is net income over the diluted shares, on the same basis as the EPS in the table. The price is that year's EPS at the P/E you set, and the yearly return runs from today's price to the year's end. These are your assumptions and your arithmetic, not an estimate of ours.

Free cash flow is operating cash flow less capital expenditure; the effective tax rate is income tax over pre-tax income; margins are the line over revenue. Gross profit is revenue less cost of revenue, and operating income is revenue less the company's own total costs, where the statement does not print those lines.

The figure a share at the top is what a discounted cash flow calls intrinsic value, worked out on your assumptions. Everything after year five is one sum: the sixth year's cash, growing at the long-run rate every year after, added up and brought back to today's money. Each year runs from the last twelve months as filed. Sales growth opens where Play it forward does: the company's own five-year rate, easing a third of the way each year toward the median of the 65 peers in Utilities (6.9% a year); change a year and the years after it follow. Operating cash flow, capital expenditure and share-based pay open at the company's own median share of sales over its last five years, shown under each row. Share-based pay is taken off because operating cash flow adds back the shares paid to staff as if they cost nothing; set it to 0 to leave it in. Capital spending counts every capital line the company files in its cash flow, such as equipment it leases to customers, software, wells or property it develops, named under the row, while the Capital expenditure row in the table below stays the one line as filed; buying a business, securities or a finished property is not counted. The discount rate opens at 10%, about what US stocks have returned a year over the long run, so it is the return you give up by holding this company instead of the market; the growth after year five opens at 3%, a little under the US economy's long-run growth in dollars, because no company outgrows it for ever. Net debt is the debt and short-term borrowings less the cash on the latest balance sheet that shows the debt; the figure per share divides what is left by the diluted share count. These are your assumptions and your arithmetic, not an estimate of ours.
