Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

indirectly financial

"These shares are owned by the Terry D. McCallister Trust dated 6/14/2013 and indirectly by Terry D. McCallister..."

trust financial

"These shares are owned by the Terry D. McCallister Trust dated 6/14/2013..."

A trust is a legal setup in which one party (the trustee) holds and manages assets—like cash, stocks or property—on behalf of other people (beneficiaries) according to instructions from the person who created it (the grantor). Think of it as a locked box with a keyholder who must follow written rules; for investors it matters because trusts influence who controls and benefits from assets, affect taxes and succession, and can change how quickly or transparently shares are bought, sold or voted.
