Required Minimum Distribution (RMD) The IRS requires that you withdraw at least a minimum amount - known as a Required Minimum Distribution - from some types of retirement accounts annually, starting the year you turn age 70-1/2. Determining how much you are required to withdraw is an important issue in retirement planning.
There are two types of seals: the earless, or true, seals (family Phocidae); and the eared seals (family Otariidae), which comprise the sea lions and fur seals. In addition to the presence of external ears, eared seals have longer flippers than do earless seals.
Other types of topical sealers for driveways are polyurethanes, epoxies and penetrating resins. Generally, epoxy or polyurethane sealers cost considerably more than acrylics and they tend to be higher build, and thus more slippery. They also don't allow for moisture vapor to move out of the concrete.
