The Globe and Mail reports in its Tuesday edition that turning retirement savings into sustainable, tax-efficient income requires you to set a mix of investment products, and then decide how much you can withdraw annually without running out of money. The Globe's Rob Carrick writes that some retirees might want help with that. Sun Life, for instance, has something called MyRetirement Income. If you judge by asset levels, incumbent products in this niche are not getting their due attention. The same applies to annuities, which were covered last week. MyRetirement Income is designed for people who are part of workplace defined contribution pension plans administered by Sun Life, which has a 36-per-cent market share in DC plan assets. If the product gains popularity, Sun Life will look at making it widely available. DC plans are more savings vehicles than pensions because it is up to you to turn what you have accumulated into retirement income. MyRetirement Income handles this pivot for you by turning your savings into income paid monthly until you reach a preselected target age -- say, 90 or 95. At that point, you are left with a zero balance. You can add money to MyRetirement Income or make a withdrawal at any time.
