I am interested in this sector, but the contingency of substantial payouts from legacy issues is an ever present issue (at least presently). Maybe this issue abates over time.
I know SEQ got caught with a $2m payout a number of years ago - to which they claimed insurance compensation. To my knowledge this has not happenend and they have gone silent on this matter. I think (code for 'I don't know for sure') SEQ may be facing a similar scenario again (Venture Egg). And that's the problem, we don't know where the land mines are...but the Royal Commission would suggest they are there...somewhere...and our court system is hell bent on making the 'bar stewards' pay.
Your issue about illiquidity of CAF is very valid.
As to takeover potential, CAF is an ideal fit, but look at the significant shareholders - Thorney Investments (look at the SXE thread to read about Alex Waistlitz) owns 26% as does COG with 20% - no dice without getting them onside. I'm not sure how these shareholders see their exit strategy.
