Sandfire, page-5

How would ADT be out of Sandfires scope?
they already own 7.5 % of the company and it only has a market cap of 115 million.
Sandfire have approached the board of ADT and asked to increase its stake by way of a capital injection. 
the main stumbling block is the founding  owners stake in ADT stopping Sandfire from making an aggressive takeover.
MOD is a totally different proposition someone is building a position quite cheaply.
