Share Buyback

I. Formal Definition

A transaction in which an organisation purchases its own outstanding shares in the open market or through a tender offer, reducing the float and returning cash to remaining shareholders. Buybacks are economically distinct from dividends in tax treatment and signalling. The federation requires buyback programs to be authorised by the board, disclosed in advance with their dollar limit and time window, and reported quarterly with executed volume and weighted average price. Buybacks above WACC are flagged for steward review under MEV-Annex:4.1.

II. Etymology

The term entered American corporate practice in the early twentieth century; the modern open market buyback regime stabilised after the 1982 SEC safe harbour.

III. Federation Usage

Federation members publish active buyback authorisations and quarterly executed volume. Repurchases above WACC are flagged in the capital allocation review. Misrepresentation of buyback economics is a Tier-2 conduct issue under TGS-002:2.3.
