thanks for the reply..
i really do understand that it is actually the assets that define liability.. my question is really this way:
consider for a moment a policyholder fund whose investment policy is very "open", and leaves almost everything to be decided by the insurer.. lets ignore regulations for a moment..
would it be beneficial, in these circumstances, for the insurer to select assets which match nature, term, currency etc of liabilities? i really do think the answer is yes, because it would help policyholders avoid unnecessary risk (e.g. why risk mismatching by duration? it may give rise to liquidity or reinvestment risk) and achieve a "disciplined" rate of return..
am i thinking correctly here?
