contractual duty to collect foreign payments, despite its failure to obtain payment for the illicit RX sales or for the maintenance charges billed to certain RX customers by SCH. Instead, the applicable finding of fact merely recites that certain customers were billed but that no one was paid for the charges.
A review of the record also fails to disclose any evidence that the parties intended SCH to guarantee collection of the foreign invoices. In fact, the practice of the parties, in which payment of commissions to either side was not made until payment was received from the customer, indicates that no such guarantee was intended. This conclusion is in accordance with the language of the contract, which makes payment by SCH conditional “[u]pon receipt of payments from the customer or SCH’s Agents Although the record contains evidence that SCH was not paid on certain amounts, it contains no evidence demonstrating that SCH’s collection efforts were insufficient. We therefore find, with respect to the award of foreign maintenance payments challenged in SCH’s second assignment of error, that the trial court erred as a matter of law in concluding that SCH owed Intrak maintenance fees “because of its direct billing of these customers.” See State, ex rel. Squire, v. Cleveland (1948), 150 Ohio St. 303, 345, 38 O.O. 161, 177, 82 N.E.2d 709, 729.
An alternative ground is asserted by Intrak as justifying the award of damages challenged in SCH’s first assignment of error, namely, that SCH made an additional promise in its letter of September 14, 1984, to pay Intrak its percentage for RX’s illicit sales. SCH claims that the promise is unsupported by either consideration or part performance. We agree with SCH’s contention.
Although the complete absence of consideration from a contract is sufficient to permit its cancellation, once the presence of such consideration is shown, a court will not inquire into the adequacy of the consideration except in cases of fraud or unfair treatment. Valuable consideration may consist of either a detriment to the promisee or a benefit to the promisor. Mooney v. Green (1982), 4 Ohio App.3d 175, 4 OBR 276, 446 N.E.2d 1135.
At trial, Intrak argued that SCH received consideration for its promise to pay Intrak’s share on illicit sales made by RX, even after RX’s agency with SCH was terminated, by its receipt from Intrak of reports of additional illicit sales made by RX. Although this information might have benefitted SCH by offsetting claims asserted by RX against it in litigation before a federal district court, the settlement contemplated by the litigation was never consummated, and RX has not performed under the agreement. Intrak also claims that it undertook at least a slight detriment by forwarding
