Assume that trust C, for the benefit of members of participating locals of National Union X, was established in 1950 and adopted by 29 locals before June 25, 1959. The subsequent adoption of trust C by additional locals of National Union X in 1962 will not constitute a fundamental change in the character of trust C, since such subsequent adoption is by employees in a related industry.
Assume the facts as stated in example 1, except that in 1965 National Union X merged with National Union Y, whose members are engaged in trades related to those engaged in by X's members. Assume further that trust D, the employee funded pension plan and fund for employees of Y, was subsequently merged into trust C. The merger of trust D into trust C would not in itself constitute a fundamental change in the character of trust C, since both C and D are for the benefit of employees of related industries.
