Court cases are not initiated overnight. It takes time for it to go through the system. People knew about these cases going through the US system. Did anyone in Temasek even bother to find out about all the risks? Unlike in Spore, companies that operate in the 1st world face all these risks.
Why should the people in Temasek bother? They are not using their money & despite the losses they still get to keep their jobs & bonuses. Any loses are just passed on to Sporeans & their CPF. This attitude exists because Ho Ching & the people working at Temasek are not being held accountable. Compare this to the successful Warren Buffet. He is investing HIS own money & HIS share holders money.
Temasek was being greedy & simply saw the Bayer investment as a pharmaceutical play & the profits They ignored the risky aspects of the investment e.g. failure in research, court suites, ..... etc. In other words they didn't do due diligence on all the risks. Losses at Temasek are nothing new. They have made huge losses & will continue to do so as long as Ho Ching & company are in charge.
To pin such accusations, one must have watertight evidence...even with that, they still can wiggle themselves out of that; for those who are holding the keys , are cushioned by many layers, they have a cloak of invincibility.
They are also able to get away with it, for the 70% of the voters endorses this, give them the rights to do whatever they want. Of course, they, whoever, can argue till the cows come home, they have, 'checks & balances', they have 'compliances' & so forth..
Even A 'good year' dare not take on the 'juggernaut of evil' the 'years' just went bad.
In short...the 70% of the voters endorse this....they should enjoy, what they ask for, deserve to find themselves in situations, they must never complain..& perpetuate this till the end of their life time & make this immortal, for it will last forever.
