Accelerated Share Repurchase

Also known as: ASR, Accelerated Buyback
A structured share-repurchase transaction in which a company contracts with an investment bank to retire a large block of stock immediately, with final share-count and price settled later based on a volume-weighted average price.

Full definition

An Accelerated Share Repurchase (ASR) is a privately negotiated, large-block buyback executed through an investment bank under a contractual forward agreement. Unlike an open-market Rule 10b-18 program — which trickles purchases over months or quarters — an ASR retires shares from the issuer's balance sheet immediately, with the final share count and per-share price determined later based on the volume-weighted average price (VWAP) of the issuer's stock over a defined averaging window.

Typical ASR mechanics:

  1. The issuer pays an upfront cash amount (e.g., $5 billion) to the executing investment bank.
  2. The bank delivers an initial tranche of shares immediately — usually 80% of the expected total — borrowed from the market.
  3. Over a 1-6 month averaging period, the bank covers its short position by buying shares in the open market.
  4. At settlement, the total share count is reconciled to the upfront cash divided by the VWAP (less a discount). The bank delivers additional shares if VWAP fell during the period, or the issuer pays/delivers shares to the bank if VWAP rose.

ASRs are most commonly used when an issuer has excess balance-sheet cash and wants to send a clear signal to the market that capital is being returned at scale, or when reducing share count immediately improves earnings-per-share before an upcoming earnings disclosure.

Frequently asked questions

What is an Accelerated Share Repurchase?
An Accelerated Share Repurchase (ASR) is a structured buyback where a company pays cash to an investment bank to retire shares immediately. The final share count is determined later based on the volume-weighted average price over an averaging period.
How is an ASR different from a regular buyback?
A Rule 10b-18 open-market program purchases shares gradually over months under daily volume and price limits. An ASR retires the full share count immediately — the issuer transfers cash to a bank in exchange for an initial share delivery, with final reconciliation later. ASRs are larger, faster, and more visible than open-market programs.
Which companies use ASRs?
Large-cap issuers with substantial balance-sheet cash and a clear desire to signal capital return at scale. Apple, Microsoft, Berkshire Hathaway, IBM, and Cisco have all executed multi-billion-dollar ASRs in recent years.
Are ASRs disclosed publicly?
Yes. ASR initiation is typically announced via Form 8-K filing. Final share settlement is reconciled in the next Form 10-Q issuer-purchase table.
