nhc takeover of dart - increased stake

NHC has increased it's holding in Dart from 12% to over 16%.

At first I was a but lazy and assumed it was through the placement.
Not so.

In the last week NHC has made ON MARkET purchases of more than 30million shares at about 20% higher than the placement.

They he'll 109m shares previously. Add 10m assuming they take up their rights plus another 10m as part of the placement to dte major sharholdes.

NHC should be right on the margin of the 19.9% limit before a takeover offer is required.

Plus they've taken shares off th market.
Great show of confidence if this doesn't lead to a takeover by NHC.

Will they bid?
