Because of this issue, the Dutch are moving to a system with DC in accumulation with a limited risk-sharing buffer fund with CDC in decumulation only, so that only retirees are sharing the risk, she said.
After considering this experience, the U.K. did not introduce "Dutch" buffers to its CDC regulation but it is proposing that CDC is extended to decumulation phase for master trusts.
As the consultation on the proposal closed on March 27, the government will consider industry response and approving potential regulation.
"Multiemployer guidance on CDCs broadens the reach and paves the way for CDCs to be accessed by even smaller sponsors," said Andy O'Regan, employer and strategic partnerships director at defined contribution and defined benefit master trust TPT Retirement Solutions, Leeds, England. TPT has £10.3 billion ($12.7 billion) across its defined benefit and defined contribution assets.
"As a multiemployer master trust which offers both DB and DC to members, a proposition like CDC, which combines attributes of both DB and DC, would fit well with our capability and expertise," he said, noting that TPT is in the process of speaking to employers about a multiemployer CDC plan.
In terms of CDC plan design, Mr. O'Regan said that single-employer CDC options are only feasible for large organizations because they are costly to build. For Royal Mail Group Ltd., which is set to launch the U.K.'s first single-employer CDC plan this year following a lengthy process, the endeavor is proving costly with the company expecting to be spending an additional £30 million over the projected cost of £400 million per year, according to half-year results released Nov. 17.
Royal Mail Collective Pension Plan, London, was approved to operate as the U.K.'s first collective defined contribution plan by U.K. The Pensions Regulator on April 13.
Interest among plan sponsors isn't waning. A poll conducted by Aon among its clients showed that 10% of employers are already looking into introducing a CDC option, with a further 14% of companies considering CDC as part of their next review.
Also, the £25 billion defined contribution multiemployer plan National Employment Savings Trust, London, is watching CDC developments.
"We welcome the DWP's consultation on CDC, as despite a few well-documented issues with traditional CDC-style schemes, we think some of the most important concepts underpinning them are worth exploring, particularly following the introduction of pension freedoms," said Zoe Alexander, director of strategy and corporate affairs at NEST.
Ms. Alexander said that NEST's research suggests plan participants prefer sustainable lifelong income and a setup where they would not need to engage with their retirement funds.
Ms. Alexander added that risk sharing can smooth returns and increase the plans' ability to invest in growth assets for longer.
"We believe new ideas are needed if we're to achieve better results for members and help them avoid many of the new risks they face in retirement," she added.
