Superior Court of Pennsylvania July 21, 1987, No. 1578 (Mitchum v. Atlantic Richfield Co.)

MONTEMURO, Judge:

This appeal lies from an Order granting appellees’ motion for summary judgment.

The underlying cause of action finds its basis in the combination of the pension plans of the three companies whose (successive) corporate mergers produced what is now the Atlantic Richfield Co. (ARCO).

In January, 1966, Atlantic Refining Co. merged with Richfield Oil Corp.
