FBDC entered into a Trade Contract with MS Maxco Company, Inc. (MS Maxco) for the execution of the structural and partial architectural works of one of its condominium projects. The Trade Contract likewise provided that MS Maxco is prohibited from assigning or transferring's any of its rights, obligations, or liabilities under the said Contract without the written consent of FBDC. FBDC received a letter from the counsel of Fong informing it that MS Maxco had already assigned its receivables from FBDC to him. Despite Fong's repeated requests, FBDC refused to deliver to Fong the amount assigned by MS Maxco. Is FBDC bound by the assignment between MS Maxco and Fong?
