Unimpaired Class
An Unimpaired Class is a Chapter 11 class whose legal, equitable and contractual rights are left unaltered by the plan or otherwise receive treatment that satisfies Bankruptcy Code Section 1124.
Unimpaired status removes the need for a class vote
Section 1126(f) conclusively presumes acceptance by a class that is not impaired.
That reduces solicitation burden and reflects that the plan is not altering the class's rights in a way that requires a restructuring vote.
Ordinary-course treatment can preserve rights
Current 2026 plans provide for allowed general unsecured claims to be paid when due under applicable law or the governing agreement and describe that treatment as rendering the class unimpaired.
Timing must therefore be evaluated against the actual contractual right, not an assumption that all claims are due immediately.
Cure and reinstatement can restore unimpaired treatment
Section 1124 provides a path under which a plan can cure specified defaults, reinstate maturity and compensate certain damages so that the holder is not treated as impaired by the default consequences.
The statutory conditions matter.
Unimpaired does not guarantee zero dispute
A class can be unimpaired while individual claims remain disputed.
Claim allowance and class impairment are different questions: one asks what is owed; the other asks what the plan does to the allowed right.
Unimpaired treatment can preserve contract economics instead of accelerating payment
Assume a supplier is owed $2 million under invoices payable over the next 60 days.
A plan says the supplier’s allowed claim will be paid according to the existing contract when due. The supplier does not necessarily receive $2 million on the effective date.
Yet its legal payment rights can remain unaltered.
Contrast that with a plan that pays the same $2 million in twelve monthly installments when the original contract required payment in 60 days. Even if expected nominal recovery is still 100%, the altered timing can create impairment.
The distinction is therefore rights preserved versus rights modified, not simply cash now versus cash later.
That is why Section 1124 analysis must begin with the original legal and contractual entitlement.
Common mistakes
Assuming unimpaired creditors always receive immediate cash Contract timing can remain in place.
Assuming unimpaired means uncontested Claim objections can still exist.
Assuming the class votes yes The class is generally presumed to accept rather than actually voting.
Example
A plan leaves general unsecured trade claims legally unaltered and provides that allowed claims will be paid in the ordinary course under their existing agreements. The class can be unimpaired even though individual payment dates occur after plan confirmation.

Professional note
Do not use 'unimpaired' as a synonym for 'paid in cash on day one.' The statutory issue is whether plan treatment preserves or properly reinstates the holder's rights.
