Individual retirement accounts and employer-sponsored retirement plans account for nearly two-thirds of advisors’ income in retirement, according to Cogent Research.

The Cambridge, Mass.-based research firm discloses this finding in a new report, “Advisor In-Retirement Income,” which explores how financial services professionals are modifying their retirement planning and income strategies in the current low interest rate environment. The study describes solutions, providers and techniques that advisors are using to address longevity, health care expenses, inflation and the spending needs of future retirees.

The report shows that employer-sponsored retirement plans account for 27 percent of advisors’ income in retirement. Personal retirement products, including individual retirement accounts and Roth IRAs provide an additional 36 percent of income.

Other sources of advisors’ retirement income, the report shows, include government-sponsored defined benefit and defined contribution plans (20 percent), business investment income (10 percent) and “other” income (7 percent).

Separately, Cogent Research reports in a new “Investor Branscape” survey that the proportion of investors who say they are “highly confident” in their primary advisor increased to 40 percent in 2012 from 36 percent in 2011. The 2012 result also surpasses that of 2010, when 37 percent of respondents indicated they were highly confident in their advisor.

The survey also pegs at 45 percent the proportion of investors who are “promoters,” and thus likely to recommend their primary advisor to someone else. This compares with 26 percent of investors whom the study identifies as “passives” (not likely to recommend) and 29 percent who are detractors (individuals who would recommend against using their primary advisor).
