Morningstar currently covers both the price return and total return indices for the S&P 100, S&P 400, S&P 500, S&P 600, S&P 1500, and S&P REIT. Previously, Morningstar Office displayed only the total return version of each index. These S&P price return (PR) and total return (TR) indices will be clearly identified with the letters PR and TR. Also, at this time our methodology will change from monthly to daily reinvestment of dividends for these S&P total return (TR) indices.
