Lack of Segregation of Duties -
Please give examples of fraud or other unethical activities or scams that could arise given the lack of segregation of duties (poor internal control) in the following situation -
A treasurer of a Temple (not-for-profit Corporation) receives donations, posts them and prepares receipt tickets off of Quick Books and distributes them to donors(every donor does get a receipt). Then prepares deposit summary and goes to the bank to deposit money. He also prepares check requests or expense reports (vouchers) and receives other invoices and gets another member to approve them for payment. He then "writes" checks off of Quick Books to pay them. Two other members sign checks before he mails them out.
Thanks in advance for your help.
