Context
An "A" code indicates receipt of shares as an award or grant (often from compensation or equity plans); such awards do not necessarily involve cash paid by the insider and are different from open-market purchases or sales. The filing does not specify vesting, restrictions, or whether the award replaces prior equity — for that, check the company's proxy statement or equity plan disclosures.
