Appendix to Part 4211 - Examples

The examples in this appendix illustrate simplified methods for disregarding certain contribution increases in the allocation fraction provided in § 4211.14 of this part.

Example 1. Determining the Numerator of the Allocation Fraction Using the Employer's Plan Year 2014 Contribution Rate (§ 4211.14(b)).

Assume Plan X is a calendar year multiemployer plan in critical status which did not have a benefit increase after plan year 2014. In accordance with section 305(g)(3)(B) of ERISA, the annual 5 percent contribution rate increases applicable to Employer A and other employers in Plan X after the 2014 plan year were deemed to be required to enable the plan to meet the requirement of its rehabilitation plan and must be disregarded. Employer A, a contributing employer, withdraws from Plan X in 2021. Using the rolling-5 method, Plan X has unfunded vested benefits of $200 million as of the end of the 2020 plan year. To determine Employer A's allocable share of these unfunded vested benefits, Employer A's hourly required contribution rate and contribution base units for the 2014 plan year and each of the 5 plan years between 2016 and 2020 are identified as shown in the following table:

	2014 PY	2016 PY	2017 PY	2018 PY	2019 PY	2020 PY	5-year total
Employer A's Contribution Rate	$5.51	n/a	n/a	n/a	n/a	n/a
Contribution Base Units	800,000	800,000	800,000	900,000	900,000	900,000	4,300,000
Contributions	$4.41M	$4.86M	$5.10M	$6.03M	$6.33M	$6.64M	$28.96M

The plan sponsor makes a determination pursuant to section 305(g)(3) of ERISA that the annual 5 percent contribution rate increases applicable to Employer A and other employers in Plan X after the 2014 plan year were required to enable the plan to meet the requirement of its rehabilitation plan and should be disregarded; benefits were not increased after plan year 2014.

Applying the simplified method, contribution rate increases that went into effect during plan years beginning after December 31, 2014 would be disregarded: The $5.51 contribution rate in effect at the end of plan year 2014 would be held steady in computing Employer A's required contributions for the plan years included in the numerator of the allocation fraction. Based on 4.3 million contribution base units, this results in total required contributions of $23.7 million over 5 years. Absent section 305(g)(3) of ERISA, the sum of the contributions required to be made by Employer A would have been determined by multiplying Employer A's contribution rate in effect for each plan year by the contribution base units in that plan year, producing total required contributions of $28.96 million over 5 years.

Example 2. Determining the Denominator of the Allocation Fraction Using the Proxy Group Method (§ 4211.14(d)).

Assume a plan covers ten employers. For 2017, three small employers were in rate history group X, representing less than 5 percent of active plan participants; employers A and B and two other employers were in rate history group Y; and employer C and two other employers were in rate history group Z. For 2018, there were changes in contribution rates for some of B's employees, and as a result, employer B is being treated as two employers, B1 and B2. B1 remained in rate history group Y because, while B1 has a significantly lower contribution rate than A, the contributions of both are subject to the same percentage increase each year. B2 was added to rate history group X. X continues to represent less than 5 percent of active plan participants, and the plan continues to ignore it in forming the proxy group. The plan forms a 2018 proxy group of three employers - A and B1 from rate history group Y and C from rate history group Z - that together represent more than 10 percent of active plan participants.

Contributions for 2018 are $1,000,000: $20,000 for rate history group X, $740,000 for rate history group Y, and $240,000 for rate history group Z, with A and B1 accounting for $150,000 and C accounting for $45,000 of the total contribution amounts.

Contribution rates for 2018 for A, B1, and C (excluding rate increases required to be disregarded for withdrawal liability purposes) and contribution base units for the three employers are: For A, 87 cents and 100,000 CBUs; for B1, 43 cents and 50,000 CBUs; and for C, 70 cents and 60,000 CBUs, as shown in rows (1) and (2) of the table below. Thus, the three employers' adjusted contributions are $87,000, $21,500, and $42,000 respectively, as shown in row (3).

Moving from the employer level to the rate history group level, the adjusted contributions for employers in the proxy group that are in the same rate history group are added together (row (4)). Those totals are then divided by total actual contributions for the proxy group employers in each rate history group (row (6)) to derive an adjustment factor for each rate history group (row (7)) that is applied to the actual contributions of all employers in the rate history group (row (8)) to get the adjusted contributions for each rate history group represented in the proxy group (row (9)).

Moving from the rate history group level to the plan level, the same process is repeated. Adjusted employer contributions for the rate history group are summed (row (10)) and divided by the total contributions for all rate history groups represented in the proxy group (row (11)) to get an adjustment factor for the plan (row (12)). Contributions for rate history group X are excluded from row (11) because no employer in rate history group X is in the proxy group. The adjustment factor for the plan is then applied to total plan contributions (row (13)) to get adjusted plan contributions (row (14)). Contributions for rate history group X are included in row (13) because - although X was ignored in determining the adjustment factor for the plan - the adjustment factor applies to all plan contributions (other than those by employers excluded from the plan's allocation fraction denominator). The plan will use the adjusted plan contributions in row (14) as the total contributions for 2018 in determining the denominator of any allocation fraction that includes contributions for 2018.
