The PGA Champions Tour, which in December named The Principal Charity Classic as its 2013 Charity of the Year, will hold a celebration event this week in Des Moines. On Thursday, PGA Champions Tour President Mike Stevens will present the award to Larry Zimpleman, CEO of Principal Financial Group Inc., along with a $30,000 donation to FORE Our Kids. Last year, The Principal Charity Classic, a PGA Champions Tour event hosted by the Community Foundation of Greater Des Moines, raised a record $1.03 million to designated children's charities in Central Iowa.
