Plan Amendment Impact Modeler
Before / after on overhang, runway, dilution, and investor concerns.
Model how a proposed plan-amendment package (additional shares, evergreen, share recycling, repricing posture) affects share reserve, overhang, runway, dilution, and the investor narrative across a forecast horizon. Pair with the Stock Plan Health Check and ASC 718 Expense Forecaster for a complete pre-read.
Deterministic engine. ISS-aware framing, not a proxy-advisor model. No AI in the calculation path. Client-side only. The plan document, listing-rule restrictions, shareholder-approval requirements, and the comp committee charter control any actual amendment.
How to use this in an amendment cycle
Step 1
Snapshot the current plan
Pull shares outstanding, awards outstanding, available reserve, and recent annual burn from the stock administration platform + cap table.
Step 2
Define the proposal
Additional shares, evergreen yes/no, repricing posture, share recycling rules. Each dial is a deliberate plan-design choice with investor-facing implications.
Step 3
Walk before / after
Compare overhang, runway, and dilution. Read the forecast walk to see how reserve runs over the company's hiring growth scenario.
Step 4
Triage flags
Investor concern flags surface high evergreen, large overhang increment, repricing without shareholder approval, asymmetric recycling, very short or very long runway.
Step 5
Hand off
Comp committee → legal (listing rules) → finance (dilution + budget) → accounting (ASC 718 expense) → IR for the proxy narrative.
What this tool is, and what it isn’t
ISS-aware, not a proxy-advisor model
The engine surfaces investor concern flags using practitioner-common reference points (high evergreen, large overhang increment, repricing posture). It does not reproduce the ISS Equity Plan Scorecard or Glass Lewis pay-for-performance models. Pull the latest proxy advisor guidance for the company's stage.
Deterministic math
Overhang = (awards outstanding + reserve) / shares outstanding. Runway = reserve / annual burn (net of evergreen replenishment). Dilution = cumulative burn / shares outstanding. Editable hiring growth multiplier.
Not legal advice
Listing-rule analysis (NYSE / Nasdaq), shareholder-approval requirements, country-specific sub-plan implications, and plan-document drafting are out of scope. Confirm with qualified counsel.

Investor concern flags - **High overhang increment**: Amendment increases overhang by 6.67 percentage points (from 10.83% to 17.50%). A jump of 5pp+ typically triggers detailed investor review. ## 5. Legal and finance question list - **Listing rule check.** Does the proposed amendment require shareholder approval under NYSE Listed Company Manual Rule 303A.08 or Nasdaq Listing Rule 5635(c)? Confirm with outside counsel. - **ISS posture.** Does the proposed amendment fall inside the ISS Equity Plan Scorecard 'pass' range for the company's stage? Pull the latest ISS U.S. policy guidance. - **Glass Lewis posture.** Does the amendment trigger any Glass Lewis red flags (high cost, repricing without approval, evergreen)? - **ASC 718 expense impact.** What is the incremental fair-value expense from the amendment under the company's accounting policy? Pair with the ASC 718 Expense Forecaster in the workbench. - **Plan doc consistency.** Does the proposed amendment require updating the plan-document share reserve language, individual-grant limits, or country-specific sub-plans? - **Disclosure timeline.** Confirm the proxy-disclosure timeline and the comp committee charter language that supports the amendment. ## 6. Recommended next steps 1. **Comp committee.** Walk the before / after snapshot and the investor concern flags with the comp committee. Confirm the size of the request against the company's 3–5 year hiring plan. 2. **Legal.** Confirm listing-rule + plan-doc + sub-plan implications. Document the rationale for any deviation from prior amendment language. 3. **Finance.** Reconcile the dilution forecast to the FY budget and the burn-rate model. Confirm investor-relations talking points. 4. **Accounting.** Pair this memo with the ASC 718 expense forecast for the post-amendment award population. 5. **TR.** Stress-test runway under the hiring growth multiplier; consider scenario sensitivity on +/- 25% headcount growth. ## Disclaimer Outputs reflect the inputs and thresholds typed above. Investor concern flags use practitioner-common reference points and are not a substitute for ISS / Glass Lewis modeling. Repricing, listing-rule, and shareholder-approval analysis is jurisdiction-specific; confirm with qualified counsel.
