If you are 40 or older and your employer just announced a layoff that touches more than one person, your severance packet contains a document that is easy to overlook. The Older Workers Benefit Protection Act calls it the group disclosure. The packet may label it "Exhibit A" or "Schedule 1" or simply "OWBPA disclosure." It is a list of job titles and ages. It is also the single most useful piece of information in the entire packet for an older worker deciding whether to sign.

This post walks through what the disclosure is, what it must contain, what to compute when you read it, and what to do when the math points at age-based selection.

What the disclosure is and where it comes from

OWBPA was passed in 1990 as an amendment to the Age Discrimination in Employment Act. The statute sits at 29 U.S.C. § 626(f). The implementing regulations sit at 29 CFR § 1625.22. Together they set the floor for any employer seeking a valid waiver of ADEA claims from a worker aged 40 or over.

A "group termination program" is OWBPA shorthand for a layoff in which two or more employees are offered the same severance deal in exchange for the same release. When that happens, the statute layers an extra requirement on top of the individual rules. The employer must give each affected employee a written disclosure of two things. The first is any class, unit, or group covered by the program, the eligibility factors, and any time limits. The second is the job titles and ages of all individuals eligible or selected for the program, plus the ages of all individuals in the same job classification or organizational unit who were not eligible or selected (29 U.S.C. § 626(f)(1)(H), Cornell LII, verified May 2026).

The disclosure exists for one reason: it converts an opaque selection process into a list with names, titles, and ages. Without the data on who was cut and who was kept, the question of whether older workers were selected at higher rates than younger workers in the same unit cannot be answered. The list converts a question into a number.

The decisional unit is the whole game

The disclosure data is meaningful only against the right denominator. OWBPA calls that denominator the "decisional unit." 29 CFR § 1625.22(f)(3) defines it as "that portion of the employer's organizational structure from which the employer chose the persons who would be offered consideration for the signing of a waiver" (Cornell LII, verified May 2026).

The decisional unit is rarely the entire company. It can be a department, a job family, a single geographic site, a project team, or a reporting chain. The employer chooses the unit based on how the layoff was actually scoped. The choice matters because it sets the comparison group.

A decisional unit drawn too narrowly hides age skew. If your manager picked three people from a five-person team and the disclosure unit is "the team," the sample is too small to compute anything reliable. Ask whether the layoff decision was actually made at the team level or at a higher level (the department, the function, the office). The answer often does not match the disclosure.

A decisional unit drawn too broadly also hides age skew. If a single 40-person engineering team was cut and the disclosure lists the entire 4,000-person company as the unit, the older-worker selection rate gets diluted by 3,960 people who were never at risk. The unit must reflect the actual decision boundary, not a convenient larger pool.

When the unit on your disclosure does not match the layoff as you understood it, ask the company in writing to confirm the decisional unit definition and to explain which manager or executive made the selection. The answer is the foundation of any later disparate-impact analysis.

What the disclosure must contain

OWBPA and its regulations specify the format. A compliant disclosure includes every element below, written in plain language the affected employee can understand.

#	Element	Source
1	Class, unit, or group covered by the program	29 U.S.C. § 626(f)(1)(H)(i)
2	Eligibility factors for the program	29 U.S.C. § 626(f)(1)(H)(i)
3	Any time limits applicable to the program	29 U.S.C. § 626(f)(1)(H)(i)
4	Job titles and ages of all individuals eligible or selected	29 U.S.C. § 626(f)(1)(H)(ii)
5	Ages of all individuals in the same classification or unit not selected	29 U.S.C. § 626(f)(1)(H)(ii)
6	Actual ages, not bands (no "ages 20 to 30")	29 CFR § 1625.22(f)(4)(iii)
7	Written in calculations the average eligible employee can understand	29 CFR § 1625.22(f)(4)(i)

The actual-ages rule deserves attention. 29 CFR § 1625.22(f)(4)(iii) states that age information must be broken down by the age of each person and that "the use of age bands broader than one year (such as 'age 20 to 30') does not satisfy this requirement" (Cornell LII, verified May 2026). Banded ages are a common defect. If your exhibit shows ranges instead of integers, the disclosure does not comply.

A disclosure listing only the terminated employees, with no data on who was retained in the decisional unit, is typically non-compliant. The statute requires both halves so the affected employee can compute the comparison.

Computing the older-worker selection rate

Once the decisional unit is correct and the data is in integers, the math is short. Count two numbers in the unit:

The number of employees aged 40 or over who were selected for termination.
The total number of employees aged 40 or over in the unit (selected plus not selected).

Divide the first by the second. That is the selection rate for the protected group. Do the same for employees under 40. Compare the two rates.

The Uniform Guidelines on Employee Selection Procedures encode a screening heuristic called the four-fifths rule. In its original hiring framing, a protected group whose selection rate for the opportunity is less than four-fifths (80 percent) of the highest group's selection rate is generally regarded as evidence of adverse impact (29 CFR § 1607.4(D), verified May 2026). For a layoff, the same logic runs in reverse on retention: if the older-worker retention rate is less than 80 percent of the younger-worker retention rate — equivalently, if the older-worker termination rate is more than 1.25 times the younger-worker rate — the disparity is large enough to warrant a closer look at the underlying selection criteria. The Uniform Guidelines were written for race and sex cases, and the EEOC has not formally extended the four-fifths rule to ADEA enforcement, so this ratio is a starting filter rather than a litigation threshold; even so, it remains a clean first-cut tool for deciding whether the disclosure data is worth taking to a lawyer.

The Supreme Court confirmed in Smith v. City of Jackson, 544 U.S. 228 (2005) that ADEA disparate-impact claims are cognizable, with the caveat that an employer can defeat the claim by showing the selection process was based on a "reasonable factor other than age" (the RFOA defense). The EEOC implements the RFOA defense at 29 CFR § 1625.7 (verified May 2026). The disclosure list is the data that lets you decide whether a disparate-impact theory is even viable for your situation.

Multi-round programs and the rolling decisional unit

A common pattern in 2025 and 2026 has been the phased layoff, where one announcement covers a partial cut, a second announcement weeks later adds another tranche, and a third announcement closes underperforming sites. When the rounds share a decisional unit and a common selection process, OWBPA treats them as one program. The disclosure for round-three employees should include round-one and round-two data as well.

If your packet only covers the round you were notified in, ask whether the prior rounds were part of the same program. The answer affects both the math (a larger denominator gives a more stable selection rate) and the legal posture (a multi-round program with consistent age skew is harder for an employer to defend than a single isolated round).

What a defective disclosure means for the waiver

29 U.S.C. § 626(f)(2) sets the consequence. A waiver of ADEA claims is not "knowing and voluntary" unless every OWBPA requirement is met, and the burden of proving compliance sits on the party asserting the waiver, meaning the employer (Cornell LII, verified May 2026). When the disclosure is missing, incomplete, banded, or built on the wrong decisional unit, the ADEA portion of the release is unenforceable. The rest of the agreement (general release of state claims, confidentiality, non-disparagement) typically remains intact, but the door to an age-discrimination claim stays open.

The Supreme Court added a second protection in Oubre v. Entergy Operations, Inc., 522 U.S. 422 (1998). An employee who signed a defective OWBPA waiver does not have to give back the severance before bringing an ADEA claim. The EEOC codified the Oubre rule at 29 CFR § 1625.23, which prohibits "tender-back" provisions and similar conditions that would punish an employee for challenging a defective waiver (verified May 2026).

You can keep the money and still file the charge. That combination is the practical reason the disclosure list matters: a defective disclosure converts a release you already signed into a release that does not bar your claim.

Common defects to flag on a first read

A first pass through the exhibit should catch the most common compliance failures. The defects below are the ones the EEOC and federal courts have repeatedly addressed.

Defect	Why it matters
Ages reported in bands (20 to 30, 31 to 40)	Violates 29 CFR § 1625.22(f)(4)(iii); ages must be integer years
Missing decisional-unit definition	Disclosure cannot be analyzed without the comparison denominator
Decisional unit excludes survivors	Statute requires both selected and not-selected halves of the unit
Inconsistent counts between cover letter and exhibit	Indicates the unit was redefined after selection; ask which is operative
Job titles missing or generic ("Employee A, Employee B")	OWBPA requires job titles and ages; anonymized labels obscure the unit analysis the statute is designed to enable
Disclosure delivered after the consideration period started	A valid consideration period never starts until a compliant disclosure is in your hands; the days that ran beforehand do not count
Round-1 data omitted from a multi-round program that shares a decisional unit	When prior rounds share the unit and selection criteria, the cumulative population is the comparison group

Any one of these defects is enough to challenge the waiver. Several together suggest the employer rushed the program and did not have legal counsel scrub the exhibit before distribution.

What to do when the numbers raise a flag

A high older-worker selection rate is the start of an inquiry, not the end. The next steps are mechanical.

First, do not sign on day one. The 45-day consideration window in 29 U.S.C. § 626(f)(1)(F)(ii) gives you time to consult an employment lawyer (verified May 2026). Most employment lawyers will do an initial OWBPA-disclosure review on a flat-fee or contingency basis. Bring the exhibit, the cover letter, and any organizational chart you have for the decisional unit.

Second, file an EEOC charge before the deadline if the lawyer agrees the numbers warrant it. The ADEA charge-filing window is 180 days from the alleged unlawful practice in most states and 300 days in deferral states with their own age-discrimination agencies (29 U.S.C. § 626(d), verified May 2026). Filing the charge does not require giving up the severance. Per Oubre and 29 CFR § 1625.23, the release does not bar the charge if the disclosure was defective.

Third, document your timeline. Keep the dated packet, the cover letter, the email confirming receipt, any verbal explanations a manager gave for the selection, and any subsequent layoff announcements. The chronology matters in any later proceeding.

The layoff calculator grades severance offers against industry benchmarks and surfaces clauses to negotiate during the consideration period. For the procedural rules that govern the 45-day clock, the 7-day revocation window, and the seven OWBPA waiver requirements in detail, see the OWBPA 21-day rule guide. For the prior-stage federal protection that may apply if your layoff is large enough, see the WARN Act 60-day notice rule. If your layoff arrives in waves rather than a single round, WARN's 90-day rolling window explains how earlier rounds can be pulled into a covered mass layoff retroactively, and the multi-round layoff hub walks through how each round changes the legal posture of the next. If your employer is offering a voluntary exit instead of an involuntary cut, voluntary separation package vs. involuntary RIF walks through which path dominates on which facts. Site context lives at /about and the data sources behind every benchmark sit at /methodology.

FAQ

What if my disclosure list shows banded ages instead of actual ages?

Banded ages violate 29 CFR § 1625.22(f)(4)(iii), which requires the age of each person eligible or selected and each person not selected to be reported individually (verified May 2026). The regulation specifies that bands "broader than one year" do not satisfy the rule. A disclosure built on bands is non-compliant on its face. The practical consequence is that the original waiver is unlikely to bar a later ADEA claim, regardless of whether you signed it. You can ask the employer in writing for a corrected disclosure with integer ages; the EEOC's published guidance treats statutory disclosure defects as going to the validity of the waiver itself, and a fresh integer-age packet paired with a new consideration period is the cleanest way an employer can attempt to cure a defective initial disclosure. Whether a redone packet is fully enforceable as to claims tied to the original layoff decision is contested; that question is one to raise with an employment lawyer before signing the second version.

How do I know if my decisional unit is drawn correctly?

The decisional unit must mirror the actual scope of the layoff decision. Ask which manager or executive selected the affected employees and which group the selector was choosing from. If the answer is "the VP picked from the entire engineering org," the engineering org is the unit. If the answer is "each director picked from their own team," each team is its own unit and the disclosures should reflect that structure. The EEOC's interpretive guidance at 29 CFR § 1625.22(f)(3) defines the unit by reference to the selection process, not the org chart (verified May 2026).

Can I keep the severance if I challenge the waiver?

Yes. The Supreme Court held in Oubre v. Entergy Operations, Inc., 522 U.S. 422 (1998) that an employee challenging a defective OWBPA waiver does not have to tender back the consideration. The EEOC codified the rule at 29 CFR § 1625.23, which prohibits tender-back conditions, prepayments of attorney fees, and other penalties for challenging the waiver (verified May 2026). The release language in the agreement may try to require return of consideration; a contract clause to that effect is unenforceable if the OWBPA disclosure was defective.

How long do I have to file an EEOC charge after a layoff?

The federal deadline under 29 U.S.C. § 626(d) is 180 days from the alleged unlawful practice (verified May 2026). The deadline extends to 300 days in deferral states, which are states with their own age-discrimination agency that has a worksharing agreement with the EEOC. The clock starts on the date you were notified of the adverse action, not your last day worked. The EEOC publishes a list of deferral states on its filing portal. Filing late forfeits the federal claim, so calendar the deadline the day you receive the packet.

Does the disclosure rule apply to a layoff of just one person?

No. OWBPA's group disclosure requirements at 29 U.S.C. § 626(f)(1)(H) trigger only when the waiver is offered as part of an "exit incentive or other employment termination program" affecting two or more employees (verified May 2026). 29 CFR § 1625.22(f)(1)(iii) defines "exit incentive program" as a voluntary program offered to a group, and "other employment termination program" as a group of employees who were involuntarily terminated and offered additional consideration for a waiver. A single-employee separation falls under the individual OWBPA rules (21 days to consider, 7 days to revoke) but does not trigger the disclosure requirement.

What does the EEOC do with an OWBPA charge?

The EEOC investigates whether the employer met every OWBPA requirement, including the disclosure obligations, and whether the underlying selection process disparately affected older workers. The agency can attempt conciliation, issue a determination letter, or sue the employer directly when systemic discrimination is indicated. More commonly, the EEOC issues a right-to-sue letter that lets the employee file in federal court. The EEOC publishes its Q&A on understanding waivers of discrimination claims in employee severance agreements, which lays out the agency's view of OWBPA compliance and the consequences of a defective disclosure (verified May 2026).
