William Books, a small book publishing company, wrote off the debt of Sun Learning Center, and the Academy of English Education, both small private schools, after it determined that the schools were facing serious financial difficulty. No notice of the action was sent to the schools; William Books simply stopped sending bills. Nearly a year later, Sun Learning Center was given a large endowment and a government grant. The resulting publicity brought the school to the attention of William Books, which immediately reinstated the account, and sent a new bill to the school, including interest for the entire time the debt was outstanding. No further action was taken regarding the Academy of English Education, which was still operational. Required: Did William Books act ethically in reinstating the debt of one client, and not the other? Explain. (10 marks)
