1. Plan administrator doesn't make required actuarial adjustments for benefit payments in a defined benefit pension plan that commence after the plan's normal retirement date as required by Internal Revenue Code (IRC) Section 411(b)(1)(H) In a defined benefit pension plan, the required actuarial adjustments or interest adjusted back payments are not being paid to participants whose retirement benefits start after the pension plan's normal retirement date. This issue tends to occur more often when plans have normal retirement ages below age 65. Many participants aren't aware that they can receive these benefits at an earlier age or opt to delay receiving their benefits until they can also receive Social Security benefits. Thus, they don't apply for their benefits. Plan administrators for defined benefit pension plans should ensure that all missed payments due to the delayed commencement of benefits are restored and that these payments are increased by the appropriate interest factor. 2. IRC Section 401(a)(9) violation (required minimum distributions) Because plan administrators for multiemployer plans typically rely on participants to apply for benefits, the IRC Section 401(a)(9) required minimum distributions aren't being met for vested participants who have terminated employment, but who haven’t yet applied for benefits. Specifically, plans fail to make required minimum distributions (defined contribution plans) or to have commenced annuities (defined benefit plans) to participants by April 1 of the calendar year following the later of the calendar year the participant turns 72 (age 70 ½ if born before July 1, 1949) or the calendar year in which the participant retires. In addition, when participants die, the rules governing the timing of these distributions to their beneficiaries aren’t being followed. Plan administrators should be more proactive in monitoring the IRC Section 401(a)(9) requirements. 3. Missing participant treatment Plan administrators don't properly search for terminated vested participants when the participant doesn't timely file for benefits. Instead these participants are classified as missing. The plan administrator should: Search plan and related plan, sponsor and publicly available records or directories for alternative contact information; Use a commercial locator service, a credit reporting agency or a proprietary internet search tool for locating individuals; and Attempt contact with participants by certified mail to the last known mailing address and through email addresses and telephone numbers. Plan administrators should be more proactive in searching for terminated vested employees prior to classifying them as missing. 4. Errors made in benefit calculations, crediting service, reduction factors and general administration Errors are made when participant benefits are calculated due to: Benefit provisions in the plan being misapplied Law being misunderstood Incorrect participant data being used or provided by the employer or the union Plan administrators should take greater care when considering the plan provisions, law changes and the accuracy of participant data when determining benefits. 5. Plan language doesn't meet legal requirements or there is conflict between plan document and other collectively bargained, joinder or participation agreements. This includes multiemployer plans incorrectly relying on a pre-approved document. This issue includes two separate, but related, errors: (a) the language in the plan document doesn't meet IRC Section 401(a) and IRS regulations and guidance, or (b) the plan document doesn't agree with the language in other legally-binding written agreements between the union and the participating employers. For example, the benefit formula in the plan isn’t the same as the one in the collectively bargained agreement, or the eligibility provisions in the plan don’t agree with those in a participation agreement. Plan administrators should first ensure that the plan document meets the requirements of IRC Section 401(a) and that the document is specific as to its terms. Plan administrators should also make sure that the terms in the plan document agree with all other legally binding written agreements between the union and the participating employers, especially when changes are made to these other written agreements. In addition, according to Revenue Procedure 2017-41, section 6.03(1), multiemployer plans can't rely on a pre-approved document and instead are always considered individually designed plans. This means the union as plan sponsor must adopt all interim amendments, and should be aware of how the interim amendments affect the other legally-binding agreements. More importantly, a pre-approved plan document is likely not set up to operate properly in a multiemployer plan environment. 6. IRC Section 401(k) plan administrator doesn't perform required nondiscrimination tests If a multiemployer plan contains a cash or deferred arrangement (a 401(k) option), many plan administrators don't perform required nondiscrimination tests, because they think the test isn't required. For this reason, many plans fail to test all eligible bargaining unit employees for nondiscrimination using the Actual Deferral Percentage (ADP) test. However, if there’s at least one bargaining unit highly compensated employee who deferred into the multiemployer 401(k) plan, the plan is required to perform nondiscrimination testing of all eligible bargaining unit employees participating in the plan. Many multiemployer plans also fail to separately test non-bargaining unit groups that are eligible to participate in the multiemployer IRC Section 401(k) plan, as a mandatorily disaggregated group. Plan administrators for multiemployer IRC Section 401(k) plans need to ensure that proper nondiscrimination testing is performed for both the bargaining and non-bargaining units participating in the plan. 7. Plan doesn't follow or doesn't have a participation agreement for each participating employer This error normally involves non-collectively bargained employees working for a union or trust fund who are participating in the plan yet don’t have a participation agreement signed or the agreement in place is not followed. These participation agreements can be in the form of a side agreement, contained within the collective bargaining agreements or provided for within the plan document. The failure to properly define the plan's eligibility and participation requirements may result in the plan not being a definite written program under the law. Before admitting a non-collectively bargained employee to the plan (which includes direct union employees), plan administrators should ensure that adequate language is formally adopted. This language should include the eligibility requirements and benefit structure for the union and the non-bargaining unit employees of participating employers. 8. Accruals/service credit is dependent on employer contributions being made Plans don't meet the definitely determinable benefit rules of Treasury Regulations Section 1.401-1(b)(1)(i) if credited service and contributions are dependent on employer contributions being made. This normally occurs when the plan requires payment from the participating employer before crediting a participant for covered service associated with that employer contribution. Plan administrators should ensure that the crediting of participant accruals and service isn't tied to the receipt of related employer contributions. 9. IRC Section 411 violations including cash out/forfeitures from lost participants, wrong vesting schedule used and errors in vesting percentages Every plan must state how participants are vested in their benefits. Normally, a participant’s vesting percentage depends on their credited service. If employers or unions don't track a participant's service correctly, the vesting percentage could be incorrect. Other vesting errors include: Erroneous cash outs and forfeitures Wrong vesting schedules being used Errors when calculating a participant's vesting percentage Suspension of benefit issues including the types of violations found in Central Laborers' Pension Fund v. Heinz, 541 U.S. 739 (2004) 10. Misuse/diversion of pension funds within the meaning of IRC Section 4975 The plan assets are used for purposes other than the benefit of plan participants or the trust. Examples include: Plan trustee uses trust assets for personal use Plan loans to a plan trustee using an interest rate that is less than the fair market rate Trust sells an asset to a "disqualified person" within the meaning of IRC Section 4975(e)(2) for less than fair market value Failure to properly allocate expenses between different trusts
