Question: what was the five year average uncompounded annual return for the s&p 500?
Evidence:
text_4: the company first announced its stock repurchase program on august 3 , 2010 .
text_8: the graph assumes $ 100 originally invested on december 31 , 2008 in each of our series a common stock , series b common stock and series c common stock , the s&p 500 index , and the stock of our peer group companies , including reinvestment of dividends , for the years ended december 31 , 2009 , 2010 , 2011 , 2012 and 2013 .
table_4: the s&p 500 of december 312008 is $ 100.00 ; the s&p 500 of december 312009 is $ 123.45 ; the s&p 500 of december 312010 is $ 139.23 ; the s&p 500 of december 312011 is $ 139.23 ; the s&p 500 of december 312012 is $ 157.90 ; the s&p 500 of december 312013 is $ 204.63 ;
Program: subtract(2013, 2008), subtract(204.63, const_100), divide(#1, #0)
