TheStreet.com Ratings' stock model projects a stock's total return potential over a 12-month period including

both price appreciation and dividends. Our Buy, Hold or Sell ratings designate how we expect these stocks to

perform against a general benchmark of the equities market and interest rates. While our model is

quantitative, it utilizes both subjective and objective elements. For instance, subjective elements include

expected equities market returns, future interest rates, implied industry outlook and forecasted company

earnings. Objective elements include volatility of past operating revenues, financial strength, and company

cash flows.

Our model gauges the relationship between risk and reward in several ways, including: the pricing drawdown

as compared to potential profit volatility, i.e.how much one is willing to risk in order to earn profits; the level of

acceptable volatility for highly performing stocks; the current valuation as compared to projected earnings

growth; and the financial strength of the underlying company as compared to its stock's valuation as

compared to projected earnings growth; and the financial strength of the underlying company as compared

to its stock's performance. These and many more derived observations are then combined, ranked, weighted,

and scenario-tested to create a more complete analysis. The result is a systematic and disciplined method of

selecting stocks.
