Wrong. TRW is not the one distributing its shares to SIAF shareholders.
It's SIAF that is distributing its TRW shares to its shareholders.
That would be like saying that if Apple held shares in GE, and GE decides to simply bypass Apple and send its shares directly to Apple shareholders, instead.
Doesn't work that way. Apple is GE's shareholder and w/b the one to receive GE shares. Then, if Apple decided to distribute them onward to its own shareholders, would do so, accordingly.
