Prosecutors portrayed Rosenberg as an un-willing participant in the political contribution scheme.

This is in stark contrast to other "riskier" contribution schemes, whose members do not enjoy similar guarantees.

Defined contribution schemes are based on the level of payments made into the fund and investment returns.

Defined contribution schemes have existed in Japan since October 2001, and as of March 2012 cover more than 4 million workers at about 16,400 companies.

Companies are instead opting for less generous defined contribution schemes.

Almost every employer has their own 'defined contribution scheme' & refuses to make contributions to a portable personal plan.

Private sector workers have already seen final salary schemes close, while returns from defined contribution schemes fall.

Those in defined contribution schemes have no idea.

More generous, in fact, than even the few remaining private sector final salary schemes, let alone defined contribution schemes.

However, there is clear evidence that this shift has not been solely towards purely individual defined contribution schemes.
