TBA ("To Be Announced", "To Be Ascertained", "To Be Arranged" or "To Be Advised"), TBC ("To Be Confirmed"), TBD ("To Be Determined/Decided") and TBR ("To Be Released", "To Be Reviewed") -- almost always used in their abbreviated forms -- denote that a datum for which the abbreviation is a stand-in is yet to be announced/confirmed/determined/released as of the time of writing.

Application

These acronyms are often used in early-to-mid-stage engineering project documentation and preliminary contracts in industry. Although used for all kinds of interim/preliminary or unknown-at-the-time-of-writing data, the most common uses in engineering documents and contracts are related to:

• dates of commencement, completion, etc; estimated total or remaining time to do a specific work task
• money amounts, i.e. costs, prices
• physical or derived quantities as-yet-to-be-obtained from tests/measurements
• engineering values depending on one or more of the above, with safety margins included

The abbreviations are also widely used in entertainment writings and listings for cast and crew information, broadcast and film release dates, and production titles for which information has yet to be confirmed, decided upon, or announced.
