Mocha is not wholly owned by Melco..
Mocha is owned by Melco Crown (MPEL). MPEL is owned 50% by 0200hk and 50% by Crown. Thus Melco (0200hk) owns 50% of Mocha Clubs.
0200hk owns 65% EGT (and with Chung/directors ~ 75%).
I think Melco (0200hk) owns a larger percentage ownership of EGT than any of its other gaming jv's/subsidiaries.
