Why this firm matters

This row is a legal-precedent / reference comparator: Liberty TripAdvisor Holdings, Inc. merged into another public company rather than completing a standalone reincorporation. Retained for legal-precedent context (e.g., Maffei v. Palkon) but treated as an excluded-from-completed-counts comparator in empirical panels.

Vote outcome — reincorporation proposal

Approval standard: DGCL §251(c) merger of Liberty TripAdvisor Holdings into Tripadvisor — typically requires majority of outstanding voting power (Series A LTRPA + Series B LTRPB voting together). Meeting type: annual.

Cohort-level robustness battery

Heckman selection-corrected ATE · Romano-Wolf step-down + BH FDR · pooled BHAR. This firm's reading is shown in context of the full cohort.

Heckman two-step selection correction (controlled-vs-widely-held)

Cohort ATE = +0.94% (SE = 7.06%, n = 2395) after correcting for controller-status selection (inverse Mills ratio = -0.062).

Romano-Wolf step-down + Benjamini-Hochberg FDR (n = 47)

This firm: per-firm adjusted p-values pending. Multiple-hypothesis correction is computed across the full cohort to control family-wise error rate at alpha = 0.05.

Pooled cohort BHAR (mover firms only)

BHAR_63d: mean = -5.60% (SE = 22.11%, n = 3, p = 0.499) · BHAR_126d: mean = +17.33% (SE = 41.17%, n = 3, p = 0.774)

Audit notes

LTRPA was Delaware-incorporated from 2014 spin-off through cash-out merger 2025-04-29. Confirmed by FY2024 10-K/A cover (DE), 2014 S-1 (DE + §203), merger 8-K (DE + §262 appraisal rights). EDGAR filer-page State-of-Inc may currently display "CO" — that label is stale SEC metadata, likely propagated from surviving entity TellurideSub LLC or clerical error. HQ has always been Englewood, CO (12300 Liberty Blvd) — possible source of confusion. Do NOT change from_state. Merger consideration $0.2567 cash/common share. Per Wave 5-A primary-source verification.
