In today's difficult macro environment, challenging credit markets, and the low interest rate environment, it is tough to find attractive dividend plays.

To create the list below we began by screening the S&P 500 for dividend stocks paying yields between 1-5%, and with sustainable payout ratios below 50%. We excluded stocks with yields above 5% so that we could avoid the riskier names.

Additionally, we looked for companies that appear undervalued relative to their cash flows, indicated by **high ratios of levered free cash flow/enterprise value.** Levered free cash flow plays an important role in paying for dividends and further expansion of the business.

Levered free cash flow is the free cash flow after deducting interest payments on outstanding debt. Enterprise value is the sum of the firm's value from all ownership sources: market cap, outstanding debt, and preferred shares. When companies have ratios of levered free cash flow/enterprise value in excess of 10%, it may indicate that the company as a whole is being undervalued.

This ratio gives us the money that the business can use to grow and pay dividends to shareholders. Any possibility of a dividend payout nowadays is looked at positively.

Finally, we screened that universe for those that appear **undervalued relative to the Graham Number**. The Graham Number is a measure of maximum fair value created by the "godfather of value investing" Benjamin Graham.

It is based on a stock's EPS and book value per share (BVPS).

Graham Number = SQRT(22.5 x TTM EPS x MRQ BVPS)

The equation assumes that P/E should not be higher than 15 and P/BV should not be higher than 1.5. Stocks trading well below their Graham Number may be undervalued.
