Shimming bath walls for cement board

I just installed this American Standard tub in my bathroom that has these 'ledges' where it meets the studs rather than the more common flanges that join flush with the studs. I did get everything secured, but now my problem is with the cement board for the shower walls. I'm using 1/2" Hardibacker, most of which will 'sit' on the 'ledges' which doesn't look right -- I thought the cement board needs to go over the top edges of the tub so that any moisture captured by the cement board will seep down into the tub.?? Am I going to have to shim all my studs to accomplish that? (or alternatively, build up the walls with say a 1/4" Hardibacker before installing the 1/2" panels?)

Interesting, a couple layers of lathe would bring the studs out enough to run the tile board past the lip, just keep it up off the tub about 1/4".
Most people would just use 1/2 tile board and install the tile past the lip, but I agree with you on having that drain plain out beyond that lip.
