Basic Subscription Right

A Basic Subscription Right is the primary entitlement granted in a rights offering that allows an eligible holder to purchase a stated amount of new securities at the Subscription Price before the offering expires.

Updated 2026-09-02 · Foundation

How it works

The offering documents define how many securities each right permits the holder to buy and how rights are allocated. The entitlement is often proportional to ownership on the Record Date or, in a restructuring, to eligible claims or holdings. Exercising the Basic Subscription Right can also be a prerequisite for access to an Oversubscription Privilege.

The basic right defines the holder’s initial allocation

The offering specifies the ratio between existing ownership or eligible claims and the securities available for purchase.

The holder can often exercise all, some or none

Offering terms determine whether partial exercise is permitted and whether partial exercise affects other privileges.

Full exercise can unlock oversubscription

Many offerings require the holder to exercise the basic entitlement fully before requesting additional unsubscribed securities.

The right expires if not exercised

Unused rights generally cease to have value after the applicable Exercise Deadline unless they were transferable and sold before expiration.

Worked example: fractional entitlement

If each right buys 0.071193 of a unit, a holder with 10,000 rights can subscribe for approximately 711 whole units after applying the offering’s rounding rules.

Why the allocation ratio matters

Two offerings with the same Subscription Price can require very different capital commitments depending on how many securities each right permits the holder to buy.

Common mistakes

Treating receipt of a right as receipt of the underlying security; overlooking the subscription ratio; assuming partial exercise preserves oversubscription eligibility; and ignoring rounding rules.

Example

Each eligible holder receives one right for every share owned on the Record Date, and each right permits purchase of 1.145 new shares at $1.00 per share. A holder with 1,000 rights can exercise the basic entitlement according to that formula.

Professional note

Keep entitlement and exercise separate. Receiving Basic Subscription Rights does not mean the investor owns the underlying new securities until the rights are validly exercised and required consideration is funded.
