The Sharpe ratio can be manipulated by portfolio managers seeking to boost their apparent risk-adjusted returns history. The risk-free rate is subtracted from the portfolio return to calculate the Sharpe ratio. Alternatively, an investor could use a fund's return objective to estimate its projected Sharpe ratio ex-ante. But yes, if you want to annualize you multiply by sqrt(12), and for three years you should multiply by sqrt(36). The investors use the Sharpe ratio formula to calculate the excess return over the risk-free return per unit of the portfolios volatility.
