UK - Almost half of FTSE100 directors are either still members of open defined benefit schemes or retain benefits under closed schemes, according to research by Incomes Data Services.
And the value of the UK's top company directors' final salary pension pots averages £2.8m ($4.4m), which could buy an annuity worth more than £170,000 a year.
The research by IDS - an employment information and research service - also revealed FTSE100 companies contributed on average £159,762 a year into directors' defined contribution schemes - equivalent to 25% of their annual salary.
IDS's Executive Compensation Review editor Steve Tatton said: "Until recently, executive directors have been cushioned from the worst effects of the deteriorating pension provision faced by most employees, however both the last and new governments promoted tax changes aimed at reducing the benefit from ‘top hat' schemes.
"While pension provision for board directors has remained generous, much of the workforce over the last few years has been going through a process of having the value of the payments into their scheme reduced."
The review further found both DB and DC contributions to FTSE100 directors' schemes were significantly higher than the new £50,000 annual limit on tax relief contributions imposed in April.
According to the research, the median value of cash-in lieu payments - paid instead of a pension contribution when the total retirement pot has reached its tax beneficial limit - to FTSE100 chief executives is £160,810 a year, while the figure for all FTSE100 board directors stands at £141,250 a year, equal to 25% of salary.
Tatton added: "To ensure that senior executive compensation remains competitive, remuneration committees have had to review their boardroom pay plans in light of changing circumstances. Hence the new emphasis on cash payments."
