Always? No ar. Last few years is on tbe higher side.
Even if it does cut bonus, u already save on the premium, u can use the difference and grow too.
Now in history all insurers cut bonus before already, even TM that nv cur bonus before, cut bonus this year.
For par plans, I believe insurers have to have a mix of local bonds, overseas bonds, local equities, overseas equities and other assets. In order to have the "guaranteed" components, they typically hold 70% in fixed income assets and as we all know, we have been living in a low interest environment for very long. So quite naturally, the par fund returns will not be that great and is declining if we look at a longer time horizon...so if they cut bonus, it is understandable, as much as we don't like it.
Having said that, I think the ethics of the insurer is very important. My personal experience as follows:
AIA: Cut and cut and cut (3 times over the years). Never restore a single cent back during better times.
GE: So far so good. There was 1 year ( I think 3 years back?) they declared an additional 1% to reward the policyholder. As of now, it is better than the initial projection.
Income: They did a major re-structure after Tan Kin Lian left...so the structure of the plan was also "revamped". As of now, it is better than the initial projection.
TM: No change.
I am not saying GE/Income/TM is better than AIA.
The lesson learnt here is diversify - don't trust a specific insurer too much.
