From the Paper:

"The best proxy for the risk free rate in the market is treasury securities. We will examine the rate of return on 1-year treasuries at the time of the purchase. In November 2006, the yield curve was inverted, and 2 year treasury notes were yielding 4.718%. This is the risk free rate used in the CAPM calculation. The beta was calculated to be 1.068. The market return in the period was calculated to 7.29%. Thus, the expected rate of return on this investment is 4.718 + 1.068 (7.29 - 4.178) = 8.04%."
