LBO Purchase Price Assumptions

Hi all,

Quick question about purchase price assumptions in an LBO- many of the practice cases I've seen simply give you an assumption for entry multiple or premium paid. I'm looking at a different (more realistic one) in which they give you a list of comps and their respective multiples. If my company is right at the median of these comps, what would be the right approach for an appropriate purchase price (if the company's multiple were say, below that of the median, one approach would be to find the implied price/share from applying that median multiple, which should be higher than the current price). Maybe looking at the 52wk high for the business? I've also thought about whittling down the comps list based to be more narrow based on size and other characteristics. 

Thanks!
