Title 29 › Chapter CHAPTER 18— - EMPLOYEE RETIREMENT INCOME SECURITY PROGRAM › Subchapter SUBCHAPTER I— - PROTECTION OF EMPLOYEE BENEFIT RIGHTS › Subtitle Subtitle B— - Regulatory Provisions › Part part 2— - participation and vesting › § 1060
Plans run by more than one employer must often be treated as if all the workers and employers were one company for key pension rules. That means rules about vesting, benefit limits, and minimum funding are applied as if everyone worked for a single employer, with special rules for breaks in service set by the Secretary. Service with a predecessor employer can count as service for the current employer. Employers that are part of a controlled group or are under common control are also treated as one employer for these rules, and minimum funding is figured for the whole group and then divided among employers under Treasury rules. A small employer can run an "eligible combined plan" that has both a defined benefit plan and a 401(a) individual account plan in one trust. To qualify, the plan must meet rules about benefits, contributions, vesting, and fairness. Key numbers: the defined benefit must give an accrued employer-funded retirement at least 1% per year of service up to 20% of final average pay (final pay is the best up to 5 consecutive years). If it meets certain interest-credit rules, pay credits by age must be at least: age 30 or less = 2%; over 30 but under 40 = 4%; 40–49 = 6%; 50 or over = 8%. The account plan must be an automatic contribution plan that treats each eligible worker as having elected 4% deferrals unless they opt out, and the employer must match 50% of employee deferrals up to 4% of pay. Vesting rules: employer-funded benefits become 100% nonforfeitable after 3 years of service; matching contributions are immediately nonforfeitable and certain nonelective contributions become 100% after 3 years. Auto-enroll plans must give a notice and a reasonable time to opt out before the first contribution and yearly notices. An eligible combined plan must be treated as a single plan for some rules, and if the combined plan is terminated the defined benefit and defined contribution parts must be ended separately. Definitions (one line each): eligible combined plan = a small-employer plan with a defined benefit and a 401(a) account plan held in one trust; applicable individual account plan = an account plan that includes a qualified cash-or-deferred (401(k)) arrangement; qualified cash or deferred arrangement = the 401(k) type of plan; CSEC plan = certain multi-employer defined benefit plans that meet the listed employer and date criteria. Plans that meet the CSEC definition are treated as CSEC unless the sponsor opts out by the end of the first plan year beginning after December 31, 2013; if treated as CSEC, certain Pension Protection Act rules stop applying from the date the plan becomes a CSEC plan.
