The Plaintiffs and the Defendants contributed each of the amount of KRW 450 million to each of the same partnership business investments, but the amount of KRW 450 million to be contributed by the Plaintiffs was KRW 20 million and KRW 300 million to be paid by the Defendants, respectively.

Since then, it recognized the plaintiffs' ownership of 1/2 of the aggregate extraction equipment, such as dredging and sorting machines purchased with a partner deposit, and the defendant D agreed to pay half of the amount calculated by deducting necessary expenses for the operation of the business from the business income to be earned by running an aggregate extraction business in the name of the defendant company and E, as dividends to the plaintiffs.
