          I typically loop over the array and do the calculations. I am doing this for over 10 thousand records and have not noticed any performane issues.

          I call a function after my collection has be recieved. I also call the same function after any filters etc.

          Something like this.
          public var totalCount:String='';
          public var sumPrice:String='';

          private function calcDealAmount():void
          var sum : Number = 0;
          var count : Number = 0;

          var length : int = arCollection.length;
          for( var i : int = 0; i < length; i++ )
          var item : Object = arCollection.getItemAt( i );
          var value : Number = item["Price"];
          if( ! isNaN( value ))
          sum += value;
          count += 1;
          totalCount = count.toString()'
          sumPrice = sumUnfunded.toString();

          You can easily add additional columns to today as needed.
