    $123.71                    $ 116.62
    $121.32                    $ 114.88
    $121.72                    $ 115.38
    $122.34                    $ 115.11
    $122.42                    $ 114.40
    $120.14                    $ 117.02
    $123.63                    $ 113.91
    $122.19                    $ 116.89
    $122.44                    $ 121.87
