The stockholder of record is a person or entity owning shares as of a particular Record Date. In this case the record date is the latest date by which you must be a shareholder, in order to vote in the annual meeting.
A registered stockholder (“record owner”) is a stockholder whose share ownership in a company is recorded directly on the books of the company’s transfer agent. If you own company shares through a bank, broker or other intermediary, then you are a beneficial stockowner. Your holdings are considered to be held in "street name" through your bank, broker or other intermediary, who would send the proxy material and voting instructions to you directly.
Street name owners with questions regarding their proxy material should contact their bank, broker or other intermediary directly for assistance.
