## Definition

a short way of writing 'Proprietary' in the names of private companies, mostly in Australia and South Africa. It shows that the company is private and has limited owners.

For teachers: an abbreviation for 'Proprietary', used in company law to indicate a private company that does not offer shares to the general public. Common in Australian and South African business nomenclature.

## Examples

- The business is registered as Smith & Sons Pty Ltd.
- When reviewing the contract, the lawyer noted that the vendor was a Pty company registered in New South Wales.
- The transition from a Pty entity to a public company requires significant regulatory filings and a complete restructuring of the board to meet transparency standards.

## Pitfalls

- Not "The Pty of the company" but "The company is a Pty Ltd" — Pty is an abbreviation used within a formal name, not a noun used to describe the concept of ownership itself.

## Usage notes

- Almost exclusively used as a post-nominal abbreviation in company names, typically followed by 'Ltd'.
