How The Plan Works

Credits and Vesting

The amount of time you work in a job covered by the Plan counts in several important ways. It determines whether you are eligible for a pension and how much your pension will be. For these purposes, the time you work as a Participant of the Plan is measured in two ways--in years of Credited Service and in Pension Credits. After you become a Participant in the Plan, you receive both Credited Service and Pension Credit during the time your employer contributes to the Plan with respect to your work. This period of time is referred to as "after your contribution date" and the credit earned is called Credited Future Service or Contributory Credit. You may also receive Credited Service and Pension Credit for work performed before your contribution date. This Credited Service earned is called Credited Past Service. Please refer to your Summary Plan Description for more detailed information on Credited Service Before or After Your Contribution Date.

Becoming Vested

A Participant achieves Vested Status under the circumstances described below:

Beginning January 1, 1998
A Participant achieves Vested Status if he has at least one Hour of Service after December 31, 1997, and has accumulated 5 Years of Credited Service, without a Permanent Break in Service. However, a Participant who does not have at least one Hour of Service after December 31, 1997, attains Vested Status in accordance with the following.

Exception: An Employee achieves vested status and will not be required to reestablish Participation as described in the plan document nor meet the one Hour of Service requirement as described above if all of the following circumstances exist:

  • The Employee has accumulated at least 5 Years of Credited Service without a Permanent Break in Service.
  • The Employee has been unable to work in Covered Employment because of a permanent disabling condition for which the date of onset, as established by the Social Security Administration, was on or before January 1, 1998 and Social Security Disability Benefits were received on or after January 1, 1998.

Special Vesting, Minimum Benefit, and Compensation Rules 
The following rules will apply only to Employees not included in a unit of Employees covered by a Collective Bargaining Agreement requiring Contributions to this Plan and only if the Plan as a whole becomes Top-Heavy. These Employees are referred to as Top-Heavy Employees.

Vesting

  • If the Plan becomes Top-Heavy the vesting schedule set forth below applies to the accrued benefit of every Top-Heavy Employee who has at least one Contributory Hour while the Plan is Top-Heavy. Participants who do not have a Contributory Hour while the Plan is Top-Heavy will have their vesting determined under the regular vesting schedule. Any accrued benefits which were forfeited before the Plan became Top-Heavy will remain forfeited.
  • Special Vesting Schedule.If the Plan becomes Top-Heavy, the following vesting schedule applies instead of the Plan’s regular vesting schedule to the Participants defined below:
Years of Vesting Service Percentage
2 20
3 40
4 60
5 80
6 or more 100
  • End of Top-Heavy Status.If, after being determined to be Top- Heavy, the Plan ceases to be Top-Heavy, then
    • The nonforfeitable percentage of a Participant’s accrued benefit before the Plan ceased to be Top-Heavy will not be reduced;
    • Any Top-Heavy Employee with 5 or more Years of Credited Service at the time the Plan ceased to be Top-Heavy will have the vesting schedule above applied to his accrued benefits whenever earned; and
    • Any Top-Heavy Employee with less than 5 Years of Credited Service at the time the Plan ceased to be Top-Heavy will have the Plan’s regular vesting provisions apply to all benefits accrued after the Plan ceased to be Top-Heavy.

Special Minimum Benefit Rules.

  • If the Plan becomes Top-Heavy, then for the first year that the Plan is Top-Heavy, and for all subsequent years during which it is Top-Heavy, the minimum benefit set forth in Subsection b.(2) below applies to all Top-Heavy Employees (other than Key Employees) who have a Year of Credited Service during that Plan Year. 
  • Special Minimum Benefit.If the Plan becomes Top-Heavy, the minimum Regular Pension benefit for Top-Heavy Employees (other than Key Employees) is the greater of (a) the Plan’s basic Regular Pension Benefit determined by the plan, or (b) 2% of the Participant’s Average Top-Heavy Compensation for each Year of Credited Service beginning after December 31, 1983 during which the Plan was Top-Heavy, up to a maximum of 10 years. 
  • Average Top-Heavy Compensation. The average Compensation for work performed while a Participant in this Plan for the period of consecutive Top-Heavy Years, not exceeding 5, during which the Participant had the greatest aggregate Compensation. Top-Heavy Years are those Plan Years beginning on or after January 1, 1984 for which the Plan is determined to be Top-Heavy.

Compensation Limitation. If the Plan is Top-Heavy for any Plan Year beginning on or after January 1, 1984, the amount of any Top-Heavy Employee’s Compensation for all purposes of the Plan other than determining Key Employee status can not exceed $200,000.

The $200,000 limit on annual compensation above shall be adjusted for cost-of-living increases in accordance with IRC §401(a)(17)(B). The cost-of-living adjustment in effect for a calendar year applies to annual compensation for the determination period that begins with or within such calendar year.

In determining benefit accruals in Plan Years beginning after December 31, 2001, the annual compensation limit above, for determination periods beginning before January 1, 2002, shall be $200,000.

Non-Working Periods

If a person has a Break in Service before he has become a Vested Participant, it has the effect of canceling his participation, his previous Years of Credited Service and his Pension Credit. However, a Break in Service may be temporary, subject to repair by sufficient amount of subsequent Credited Service. A longer Break in Service may be permanent. The Break in Service rule does not apply to a Pensioner or a Vested Participant.

Permanent Breaks in Service Before January 1, 1976
Between the Contribution Date and January 1, 1976, a person will have incurred a Permanent Break in Service and his Credited Service and accrued benefits were cancelled if after the January 1 coinciding with or next following his Contribution Date failed to earn at least one quarter of Credited Future Service as a result of Contributory Hours in any period of three consecutive calendar years, unless (1) such person was permanently and totally disabled on or before January 1 of the year in which Contributions began for the Bargaining Group in which he was employed at the time he became disabled, or (2) for periods prior to May 1, 1963 that person earned one quarter of Credited Future Service within the three consecutive twelve-month periods immediately following May 1, 1960.

If a person incurred a Permanent Break in Service before January 1, 1976, which would not have occurred if moratorium years under the Job Placement Regulations of a Collective Bargaining Agreement were excluded from the period, and if during each of the excluded years the person was continuously registered under the Job Placement Regulations and available for work in Covered Employment, all of his cancelled years of Credited Service and Pension Credit will be reinstated and his Separation from Covered Employment cancelled on the first day of the month coincident with or next following his subsequent accumulation of five years of Credited Service, without an intervening Separation from Covered Employment, but only if he returned to Covered Employment and earned some Credited Future Service within two Calendar Years following the date his Break in Service occurred.

One-Year Break in Service After December 31, 1975
A person will have a One-Year Break in Service on December 31, 1976 if (i) he was younger than age 60 and did not work at least 350 Hours of Service after January 1, 1976, or (ii) he was 60 or more years of age during the Calendar Year and did not work at least 300 Hours of Service in Covered Employment after January 1, 1976.

A person will have a One-Year Break in Service on December 31, 1977 if (i) he was younger than age 60 and did not work at least 350 Hours of Service after January 1, 1977 or (ii) he was 60 or more years of age during the Calendar Year and did not work at least 300 Hours of Service in Covered Employment after January 1, 1977.

A person will have a One-Year Break in Service in any Calendar Year after December 31, 1977 in which he fails to work at least 500 Hours of Service in Covered Employment.

A person will have a One-Year Break in Service in any Calendar Year after December 31, 1980 in which he fails to work at least 350 Hours of Service in Covered Employment.

Hours of Service in Continuous Non-Covered Employment after December 1, 1976 shall be counted in determining whether a Break in Service has been incurred.

A One-Year Break in Service is repairable, in the sense that its effects are eliminated if, before incurring a Permanent Break in Service, the Employee subsequently earns a fraction of a year of Credited Service in accordance with the plan document. More specifically,

  • Previously earned Years of Credited Service and accrued benefits are restored;
  • Nothing in this paragraph changes the effect of a Permanent Break in Service.

Permanent Break in Service After December 31, 1975 and Before January 1, 1986
A person will have a Permanent Break in Service if he had consecutive One-Year Breaks in Service, including at least one after December 31, 1975, that equal or exceed the number of full Years of Credited Service which he had preciously accumulated.

If a person incurred a Permanent Break in Service before January 1, 1986, which would not have occurred if moratorium years under the Job Placement Regulations of a Collective Bargaining Agreement were excluded from the period of the Break, and if during each of the excluded years the person was continuously registered under the Job Placement Regulations and available for work in Covered Employment, all of his cancelled years of Credited Service and Pension Credit will be reinstated and his Separation from Covered Employment cancelled on the first day of the month coincident with or next following his subsequent accumulation of five years of Credited Service, without an intervening Separation from Covered Employment, but only if he returned to Covered Employment and earned some Credited Future Service within two Calendar Years following the date his Break in Service occurred.

Permanent Break in Service After December 31, 1985
A person will have a Permanent Break in Service if he has consecutive One-Year Breaks in Service, including at least one after December 31, 1985, that equal the greater of five or the aggregate number of full Years of Credited Service which were preciously accumulated.

If a person incurred a Permanent Break in Service after December 31, 1990 and before January 1, 1993, which would not have occurred if moratorium years under the Job Placement Regulations of a Collective Bargaining Agreement were excluded from the period of the Break, and if during each of the excluded years the person was continuously registered under the Job Placement Regulations and available for work in Covered Employment, all of his cancelled years of Credited Service and Pension Credit will be reinstated and his Separation from Covered Employment cancelled on the first day of the month coincident with or next following his subsequent accumulation of five Years of Credited Service, without an intervening Separation from Covered Employment, but only if he returned to Covered Employment and earned some Credited Future Service within two Calendar Years following the date his Break in Service occurred.

However, the foregoing rule will only apply to a Non-Bargained Employee who has at least one Hour of Service after December 31, 1988, if the Break in Service occurs before he has earned five Years of Credited Service.

Grace Periods After the Contribution Date
A Participant who is absent from Covered Employment will be allowed grace periods under the following circumstances, if he is unable to earn at least one quarter of Credited Future Service as a result of Contributory Hours of work in any period of three consecutive calendar years.

  • A Participant will be allowed a grace period of up to two consecutive years when he was totally disabled from work as an Employee.

Grace periods allowed under this section will be granted for each period of disability and can not be combined with grace periods permitted after December 31, 1976 to exceed two years, or after December 31, 1989 to exceed five years.

  • A Participant will be allowed an indefinite grace period for periods of employment after the Contribution Date in one of the following classifications: 

    • Full-time paid employment with the International Union of Operating Engineers;
    • Employment with a public agency in the type or kind of craft work covered by a Collective Bargaining Agreement performed in the geographical jurisdiction of the Union;
    • Employment in a supervisory capacity above the rank of foreman with a Contributing Employer;
    • Employment under contract initially with a Contributing Employer, or with a Joint Venture in which a Contributing Employer participated, on a project located outside of the United States and continued employment under contract on the project by a Contributing Employer or by a Joint Venture in which a Contributing Employer participated whether or not with the initial Contributing Employer or Joint Venture; and
    • Employment with an employer (i) not obligated to contribute to this Pension Fund, but (ii) who was signatory to a Collective Bargaining Agreement with the Union and (iii) who had a Recognized Company Pension Plan in which the Participant participated; and
    • Employment covered by a Collective Bargaining Agreement with the International Union of Operating Engineers, or any of its affiliates on a project outside of the United States.

Grace Periods After December 31, 1976

  • A Participant who was absent from Covered Employment because of an occupational disability will be allowed a grace period not to exceed 24 months for the period for which Workers' Compensation temporary disability benefits were paid, or which constituted a valid waiting period for these benefits.

Grace periods allowed under this section will be granted for each period of disability and can not be combined with grace periods permitted after the Contribution Date to exceed two years, or after December 31, 1989 to exceed five years.

  • A Participant who is absent from Covered Employment after December 31, 1985, because of Maternity or Paternity Leave will be credited with a maximum of 501 Hours of Service for the period of leave.

Maternity/Paternity Leave Defined: A Participant is on Maternity or Paternity Leave if the Participant is absent from work by reason of the pregnancy of the Participant, by reason of the birth of a child of the Participant, by reason of the placement of a child with the Participant in connection with the adoption of the child by the Participant, or for the purpose of caring for the child during the period immediately following the birth or placement.

Grace Periods after December 31, 1989
A Participant who was absent from Covered Employment because he was totally disabled from work as an Employee or because of an occupational disability for which Workers' Compensation temporary disability benefits were paid (or which constituted a valid waiting period for such benefits), will be allowed a grace period of up to five consecutive years.

Grace periods allowed under this section shall be granted for each period of disability and shall not be combined with grace periods after the Contribution Date and grace periods after December 31, 1976 to exceed five years.

A grace period does not add to a Participant's Credited Service; it is a period which is to be disregarded in determining whether the Participant has worked sufficient hours in Covered Employment to prevent a Permanent Break in Service. In order to secure the benefits of a grace period, a Participant must give written notice to the Board of the circumstances entitling the Participant to such grace period, and must submit such written evidence as the Board may require.

Effect of Permanent Break in Service
If a person is not a Vested Participant has a Permanent Break in Service:

  • His previous Years of Credited Service and Pension Credit are cancelled, and
  • His participation is cancelled; new participation is subject to the provisions of a Reinstatement of Participation.

Military Service After the Contribution Date
A Participant who is absent from Covered Employment due to Qualified Military Service will be credited hours towards the accumulation and accrual of Credited Service and benefit accruals for such period of Qualified Military Service if he or she returns to Covered Employment within the period during which he or she retains reemployment rights under the Uniformed Services Employment and Reemployment Rights Act of 1994 ("USERRA").

Credited Service and benefit accruals shall be credited for such Qualified Military Service based on the average number of hours worked in a week by the Participant during the twelve-month period immediately preceding such military service, but not less than 30 hours per week for such military service. Contributions for Qualified Military Service shall be required to be an expense of the Plan and no additional Employer Contributions shall be required.

Military Service Before the Contribution Date
A Participant will be granted one Year of Credited Past Service for (i) each year of military service prior to his Contribution Date in the Armed Forces of the United States for the period during which he retained reemployment rights under federal law, or (ii) for each year of imprisonment by a declared enemy nation, provided the Participant was employed in work of the type for which Credited Past Service is granted immediately prior to such military service or to the employment in the war zone which resulted in his imprisonment.

A Participant will also be granted Credited Past Service for partial years of military service or imprisonment, of one quarter of Credited Past Service for each three months of military service or imprisonment. However, a Participant may not receive more than two Years of Credited Past Service for all periods of imprisonment prior to the Contribution Date.
