Haven't heard any rumblings about competing offers....$13.50 still the best bid.
Interest rates have increased 57% since Murdock was doing his due dilligence (10yr from 1.75% to 2.75%). This significantly lowers his IRR, plus add in the +$1.50 increased offer and his expected return has to look much worse than he originally thought. Seems highly unlikely he would be willing to increase his offer.
I can't see another player stepping in given the debt load, business volatility, and Murdock's ownership stake.
Looks like arb guys are just pricing this thing off 50% probability of $14 offer and 50% probability of $13.50. I see the probabilty of $14 at less than 10% (would equal an expected value of $13.55).
