In Rev. Rul. 2014-24, the IRS recently announced that certain Puerto Rico retirement plans that are qualified only under the PR Code are eligible to participate in group trusts described in Rev. Rul. 81-100 (“81-100 Group Trusts”). In general, an 81-100 Group Trust is a trust in which qualified retirement plans and individual retirement accounts pool their assets for investment purposes, if certain requirements are met. To be eligible to participate in an 81-100 Group Trust, a Puerto Rico retirement plan must meet the plan qualification requirements of Section 1081.1 of the PR Code.
