If the first calculations are done correctly, interest on money and returns on investments should yield a sufficient return, increasing the total value of the scanning account. “repo sweeps” are for companies that are concerned about the security of the bank. In this contract, funds deposited with the Bank are secured by a portion of the Bank`s outstanding loans. If the bank were to fail, the depositor would receive only the bond holdings and then sell the bonds to get their money back (unless something happens in the interim with bond prices). Eurodollar sweeps are transfers of legal funds to the bank`s offshore units, whereas they are essentially an accounting technique that allows banks to lend the funds in full without having to pay the required reserves normally required and without having to pay FDIC insurance (since the sweep is not insured). Essentially, the funds are only unsecured liabilities of the bank and, therefore, the highest interest rates are offered by the bank on day-to-day loans. A scanning account combines two or more accounts in a bank or financial institution and moves funds between them in a predetermined manner. Sweep accounts are useful for managing a constant cash flow between a cash account used for scheduled payments and an investment account that allows cash to get a higher return. Businesses and individuals should keep in mind the cost of scanning accounts, as the benefits from increased returns from non-current account investment vehicles can be offset by the fees charged for the account. Many brokers or banks charge a flat fee, while others charge a percentage of the return. Some companies choose to transfer all their funds to a sweep account if they think the higher profits will offset more than the fees they would have been given if they had left the money in their account. Other companies calculate the approximate amount needed to clean up royalties, and then scan only funds above that amount.
