Plan A is a defined benefit plan that covered both HCEs and NHCEs for most of its existence. The employer decides to wind up its business. In the process of ceasing operations, but at a time when the plan covers only HCEs, Plan A is amended to increase benefits and thereafter is terminated. The timing of this plan amendment has the effect of discriminating significantly in favor of HCEs.
Plan B is a defined benefit plan that provides a social security supplement that is not a QSUPP. After substantially all of the HCEs of the employer have benefited from the supplement, but before a substantial number of NHCEs have become eligible for the supplement, Plan B is amended to reduce significantly the amount of the supplement. The timing of this plan amendment has the effect of discriminating significantly in favor of HCEs.
Plan C is a defined benefit plan that contains an ancillary life insurance benefit available to all employees. The plan is amended to eliminate this benefit at a time when life insurance payments have been made only to beneficiaries of HCEs. Because all employees received the benefit of life insurance coverage before Plan C was amended, the timing of this plan amendment does not have the effect of discriminating significantly in favor of HCEs or former HCEs.
Plan D provides for a benefit of one percent of average annual compensation per year of service. Ten years after Plan D is adopted, it is amended to provide a benefit of two percent of average annual compensation per year of service, including years of service prior to the amendment. The amendment is effective only for employees currently employed at the time of the amendment. The ratio of HCEs to former HCEs is significantly higher than the ratio of NHCEs to former NHCEs. In the absence of any additional factors, the timing of this plan amendment has the effect of discriminating significantly in favor of HCEs.
The facts are the same as in Example 4, except that, in addition, the years of prior service are equivalent between HCEs and NHCEs who are current employees, and the group of current employees with prior service would satisfy the nondiscriminatory classification test of § 1.410(b)-4 in the current and all prior plan years for which past service credit is granted. The timing of this plan amendment does not have the effect of discriminating significantly in favor of HCEs or former HCEs.
Employer V maintains Plan E, an accumulation plan. In 1994, Employer V amends Plan E to provide that the compensation used to determine an employee's benefit for all preceding plan years shall not be less than the employee's average annual compensation as of the close of the 1994 plan year. The years of service and percentage increases in compensation for HCEs are reasonably comparable to those of NHCEs. In addition, the ratio of HCEs to former HCEs is reasonably comparable to the ratio of NHCEs to former NHCEs. The timing of this plan amendment does not have the effect of discriminating significantly in favor of HCEs or former HCEs.
Employer W currently has six nonexcludable employees, two of whom, H1 and H2, are HCEs, and the remaining four of whom, N1 through N4, are NHCEs. The ratio of HCEs to former HCEs is significantly higher than the ratio of NHCEs to former NHCEs. Employer W establishes Plan F, a defined benefit plan providing a benefit of one percent of average annual compensation per year of service, including years of service prior to the establishment of the plan. H1 and H2 each have 15 years of prior service, N1 has nine years of past service, N2 has five years, N3 has three years, and N4 has one year. The timing of this plan establishment has the effect of discriminating significantly in favor of HCEs.
Assume the same facts as in Example 7, except that N1 through N4 were hired in the current year, and Employer W never employed any NHCEs prior to the current year. Thus, no NHCEs would have received additional benefits had Plan F been in existence during the preceding 15 years. The timing of this plan establishment does not have the effect of discriminating significantly in favor of HCEs or former HCEs.
The facts are the same as in Example 7, except that Plan F limits the grant of past service credit to five years, and the grant of past service otherwise satisfies the safe harbor in paragraph (a)(3) of this section. The timing of this plan establishment is deemed not to have the effect of discriminating significantly in favor of HCEs or former HCEs.
The facts are the same as in Example 9, except that, five years after the establishment of Plan F, Employer W amends the plan to provide a benefit equal to two percent of average annual compensation per year of service, taking into account all years of service since the establishment of the plan. The ratio of HCEs to former HCEs who terminated employment during the five-year period since the establishment of the plan is significantly higher than the ratio of NHCEs to former NHCEs who terminated employment during the five-year period since the establishment of the plan. Although the amendment described in this example might separately satisfy the safe harbor in paragraph (a)(3) of this section, the safe harbor is not available with respect to the amendment because, under these facts, the amendment is part of a pattern of amendments that has the effect of discriminating significantly in favor of HCEs.
Employer Y maintains Plan G, a defined benefit plan, covering all its employees. In 1995, Employer Y acquires Division S from Employer Z. Some of the employees of Division S had been covered under a defined benefit plan maintained by Employer Z. Soon after the acquisition, Employer Y amends Plan G to cover all employees of Division S and to credit those who were in Division S's defined benefit plan with years of service for years of employment with Employer Z. Because the timing of the plan amendment was determined by the timing of the transaction, the timing of this plan amendment does not have the effect of discriminating significantly in favor of HCEs or former HCEs. See also § 1.401(a)(4)-11(d)(3) for other rules regarding the crediting of pre-participation service.
Plan H is an insurance contract plan within the meaning of section 412(i). For all plan years before 1999, Plan H purchases insurance contracts from Insurance Company J. In 1999, Plan H shifts future purchases of insurance contracts to Insurance Company K. The shift in insurance companies is a plan amendment subject to this paragraph (a).
