How we calculate the numbers
The Globe 100 ranks the best-performing, publicly traded corporations based in Massachusetts by how well they increased sales, profits, and returns for shareholders during 2009.
Capital IQ, a Standard & Poor’s business, gathered information on some 212 Bay State companies from sources that included Securities and Exchange Commission filings, commercial news services, and corporate and government reports.
To be considered for the Globe 100 a company must:
- Maintain its corporate headquarters in Massachusetts;
- Trade its shares on the New York Stock Exchange, the Nasdaq Stock Market, or the American Stock Exchange;
- Have been a public company for all of 2009; and
- Report revenue and profit for both 2008 and 2009.
Rankings are derived from financial data for the four quarters ending closest to December 31, 2009, and for corresponding quarters a year earlier.
The companies are then ranked on four criteria:
- Return on average equity, a measure of how effectively shareholder money is employed;
- One-year percentage change in revenue;
- One-year percentage change in profit margin;
- 2009 revenue.
For example, this year’s top performer, TJX Cos. of Framingham, ranked 3d in return on equity; 26th in change in revenue; 19th in change in profit margin; and 3d in revenue, giving the company a total score of 51.
Return on shareholder equity is determined by dividing 2009 net income by the average of 2008 and 2009 shareholder equity.
For the purposes of calculating return on shareholder equity, net income is defined as available for common, or net income from continuing operations before extraordinary or nonrecurring items, as filed on the company’s income statement.
If a company includes special charges — such as merger costs — in its pretax figures, the numbers will not be considered extraordinary and will be included in available for common.
Revenue for banks is calculated by adding net interest income after loan-loss provisions to total noninterest income.
Profit is calculated as net income from operations after extraordinary or nonrecurring items, as filed on the company’s income statement.
Profit margin is determined by dividing profit by revenue. The one-year change in profit margin is calculated by computing the percentage change in profit margin between 2008 and 2009.
Stock prices in all tables and stories have been adjusted for splits.
To be considered for the Growth 50 chart, a company must be based in Massachusetts and have been public in both 2008 and 2009. Companies are ranked by a composite score of two-year average annual sales and profit growth rates.
The Globe also used the same criteria to rank the top performers among publicly traded companies that are based outside Massachusetts, but are among the state’s 200 largest employers.
