Once more... Invert if statement to reduce nesting

ok...I know this is probably a well beaten dead horse, but..

public function(stringorobject param)
{
    if(somethingthatisrequiredforfunctionality == null)
    {
         somethingthatisrequiredforfunctionality = new somethingthatisrequiredforfunctionality () { member1="initialvalue", member2="anotherinitialvalue" };
         //or
        somethingthatisrequiredforfunctionality.Initialize("startupobject_or_string");
    }

    // go ahead an use somethingthatisrequiredforfunctionality
   somethingthatisrequiredforfunctionality.prepareobject(param);
   return callotherfunction(somethingthatisrequiredforfunctionality);
}

Why is resharper saying anything about reducing nesting - how the heck else do you write this? lol

Help...
