Two changes will be made to the way officers in the elite Administrative Service as well as those with judicial and key statutory appointments are rewarded, Deputy Prime Minister Teo Chee Hean announced on Monday.

Firstly, their pensions will be replaced with a long-term retention package for Administrative Service officers, and a gratuity plan for judges, the Attorney-General, the Auditor-General and the chairman of Public Service Commission.

Secondly, their bonus will no longer be based on only economic growth - the country's Gross Domestic Product - but expanded to include criteria such as the socio-economic progress of the middle- and lower-income Singaporeans, similar to those holding political appointments.

These changes follow a comprehensive review of the salary framework, which Mr Teo said concluded that current salaries are at about the right level, with no need to raise or cut them, except for some adjustments to certain salary ranges and start points.
