Sending variables between classes

Hi guys

I have two classes. A main class called core.as and a bg.as class which loads a background.

I want to send the loaded percent from bg.as to core.as

private function progressHandler(event:ProgressEvent):void { 
         
                        var percent:Number = Math.round((event.bytesLoaded / event.bytesTotal )*100 ); 
                         
                }

This is my progressHandler where i get the percent loaded and stores it in the variable called “percent” - How do i get this out to my core.as file?
