Might be a good time to go and have a browse at what happened to Slater and Gordon when they had a goodwill impairment a few years ago, in the case of CI1, it's an impairment to the tune of half their MCAP, and I appreciate that MCAP is only a value gauge of the market, but the write down that SGH did, technically shouldn't have rocked them so hard, but market reactions can and do crater otherwise solid businesses.
Also, you have to consider what an impairment indicates of management, that their DD process was flawed, and did not pick up on such an issue. Especially given goodwill, where valuations are nebulous at the very best of times.
