株式交換 / 株式移転 (kabushiki koukan / iten) — share-exchange and share-transfer regime for wholly-owned subsidiary and holding-company formation

Wiki route
This entry sits under corporate-strategy INDEX and routes into finance INDEX for the transaction-finance overlay. Read it with Kabushiki Koufu Stock Distribution Regime for the partial-control sibling (the third share-side regime), Japan Kaisha Bunkatsu Tax Regime for the asset-level contrast, spinoff decision tree for option-set placement, and Japan tender offer process for the cash-bid alternative that 株式交換 frequently follows.
TL;DR
株式交換 (kabushiki koukan, share exchange) and 株式移転 (kabushiki iten, share transfer) are the two pre-existing Japanese Companies Act mechanisms for moving an entire company under a single parent using shares, not cash, as consideration. They are the share-side organizational-reorganization tools that bracket the newer Kabushiki Koufu Stock Distribution Regime regime:
- 株式交換 makes an existing company the 100% (wholly-owned) parent of a target. The acquirer (完全親会社) issues its own shares to the target’s shareholders, who hand over all target shares; the target becomes a 完全子会社 (wholly-owned subsidiary).
- 株式移転 creates a brand-new holding company above one or more existing companies. The new 完全親会社 is incorporated at the moment of the transfer and receives all shares of each transferred company; original shareholders become shareholders of the new HoldCo.
Both differ from Kabushiki Koufu Stock Distribution Regime in one decisive way: 株式交換 and 株式移転 produce a 100% parent-subsidiary relationship, whereas 株式交付 stops at a controlling-but-partial stake (>50%, <100%). Like every Japanese reorganization, each runs on a 適格 (qualified, tax-deferred) vs 非適格 (non-qualified, taxable) axis.
The statutory layer:
- Companies Act articles 767-771 govern 株式交換; articles 772-774 govern 株式移転 (株式交付 sits just after, at 774-2 et seq.).
- Corporation Tax Act article 2(12-16) / 2(12-17) and the surrounding 組織再編成 provisions govern the 適格 / 非適格 distinction.
- Both require an acquirer / forming-company shareholders’ special resolution (2/3 threshold) and Companies Act creditor- and dissenting-shareholder-protection procedures.
1. The Two Mechanisms Side by Side
| 株式交換 (share exchange) | 株式移転 (share transfer) | |
|---|---|---|
| Parent company | An existing company | A newly incorporated company |
| Outcome | Target becomes 完全子会社 of the existing acquirer | Existing company(ies) become 完全子会社 of a new HoldCo |
| Minimum acquisition | 100% of target | 100% of each transferred company |
| Consideration | Acquirer’s own shares (cash / other property mixable) | New HoldCo’s own shares |
| Typical use | Full takeover with stock consideration; converting a listed affiliate into a wholly-owned subsidiary | Pure holding-company formation; merger-of-equals under a joint HoldCo |
| Companies Act articles | 767-771 | 772-774 |
| Decision | Both companies’ shareholders’ special resolution (2/3) | Each transferring company’s shareholders’ special resolution (2/3) |
The intuition: 株式交換 points an existing company upward over a target; 株式移転 builds a new roof over one or more companies. A single-company 株式移転 is the canonical route to a pure holding company — see holding-company conversion for the dedicated treatment of HoldCo formation, where 株式移転 is one of three competing methods.
2. 株式交換 — Share Exchange in Detail
The acquiring company (株式交換完全親会社) becomes the sole shareholder of the target (株式交換完全子会社). All target shares move to the acquirer by operation of law on the effective date; the acquirer issues consideration directly to former target shareholders.
- Listed-affiliate cleanup: the most common use is squeezing out the minority of a partly-owned listed subsidiary to take it 100%. A parent at, say, 53% can move to 100% via 株式交換, paying its own shares — converting a consolidated-but-listed subsidiary into a wholly-owned one.
- Cash-out variant: since the 2005 Companies Act, consideration can be cash or other property (対価の柔軟化), enabling a “cash-out 株式交換” that functions as a squeeze-out without a preceding TOB. This overlaps the take-private toolkit in Japan MBO / squeeze-out process.
- Dissenting-shareholder appraisal: shareholders who oppose may demand the company buy their shares at fair value (株式買取請求権) — the same minority-protection mechanic that recurs across tender-offer and squeeze-out structures.
3. 株式移転 — Share Transfer in Detail
株式移転 incorporates a new parent (株式移転設立完全親会社) whose only initial asset is 100% of the transferred company(ies). It is the standard legal route for two patterns:
- Single-company HoldCo conversion: one operating company does a 株式移転 to put itself under a freshly created pure holding company. Shareholders swap their operating-company shares for HoldCo shares one-for-one; the operating company becomes a wholly-owned subsidiary.
- Joint HoldCo / merger-of-equals: two (or more) companies each do a simultaneous 株式移転 into one new HoldCo, parking both under a common parent without merging their operating entities. Many Japanese financial groups were assembled this way — the structures populate the listed-financial-groups universe and the entities catalogued in corporate-strategy INDEX.
Because the new HoldCo is created from scratch, 株式移転 avoids any need for the parent to have pre-existing share capital to issue — contrast 株式交換, which needs an existing acquirer with issuable shares.
4. Tax Axis — 適格 vs 非適格
The 適格 (qualified) test mirrors the logic used across all Japanese 組織再編成 (corporate reorganizations) and tracks closely with the 会社分割 tests documented in Japan Kaisha Bunkatsu Tax Regime. The question is whether the share-side reorganization is treated as tax-deferred (carryover basis) or taxable (mark-to-market + deemed-dividend).
Qualified-test scenarios
- 100%-group (完全支配関係) — 株式交換 / 株式移転 within a wholly-owned group: minimal tests beyond continuation of the complete-control relationship.
- >50%-group (支配関係) — within a majority-controlled group: adds business-continuation and employee-retention (≈80%) tests.
- Joint-business (共同事業要件) — between unrelated parties: adds the full battery — 事業関連性 (business relatedness), 事業規模 OR 経営参画 (comparable scale or specified-officer participation), 従業者引継ぎ (employee retention), 事業継続 (business continuation), and 継続保有 (continued holding of the issued parent shares by specified shareholders).
Consequences
| 適格 (qualified) | 非適格 (non-qualified) | |
|---|---|---|
| Subsidiary’s assets | Stay at book value; no gain recognized | Marked to fair value in defined cases; embedded gains can crystallize |
| Selling shareholders | No immediate capital-gains tax on the share-for-share swap | Capital gain / deemed dividend can arise, especially on cash consideration |
| Cash consideration | Breaks 適格 in the joint-business case | Common trigger for non-qualified treatment |
The practical rule of thumb is identical to the other regimes: share consideration preserves 適格; cash consideration generally breaks it. This is the same fault line that separates a share-funded combination from the cash-funded take-private routes in Japan leveraged-buyout economics.
5. Where It Sits Among the Share-Side Regimes
Japan now has three share-consideration reorganization regimes. Choosing among them is purely about the target ownership percentage you want:
| Regime | Resulting stake in target | Parent | Canonical use |
|---|---|---|---|
| 株式交付 (kabushiki koufu) | >50% to <100% (partial control) | Existing | Friendly partial-control acquisition with stock — see [[corporate-strategy/kabushiki-koufu-stock-distribution-regime |
| 株式交換 (kabushiki koukan) | 100% (wholly-owned) | Existing | Full takeover / listed-affiliate cleanup with stock |
| 株式移転 (kabushiki iten) | 100% (wholly-owned) | New HoldCo | Holding-company formation / joint HoldCo |
For asset-level (rather than share-level) reorganizations — moving a business rather than shares — use Japan Kaisha Bunkatsu Tax Regime instead. The full option set, including the divestiture side, is mapped in the spinoff decision tree.
6. Procedural Timeline
Both regimes share the Companies Act reorganization timeline, which sets the realistic floor on execution speed:
| Step | Statutory minimum | Notes |
|---|---|---|
| Board approval of 株式交換契約 / 株式移転計画 | — | Same-day possible |
| Pre-meeting disclosure of plan documents at head office | ≥ 2 weeks before shareholders’ meeting | For shareholder / creditor inspection |
| Shareholders’ meeting special resolution | — | 2/3 special-resolution threshold |
| 債権者保護手続 (creditor objection) where required | ≥ 1 month objection period | Required where new debt-like consideration or specified conditions apply |
| 反対株主の株式買取請求 (appraisal demand window) | Statutory window around the effective date | Dissenting-shareholder buy-out at fair value |
| Effective date + registration | Filing within 2 weeks of effect | 株式移転 also registers the new HoldCo |
A non-contentious 株式交換 or 株式移転 typically runs 2-3 months from board approval; listed-company deals add FSA / TSE disclosure overhead under large-shareholding disclosure and the listing rules referenced in the IPO listing / disclosure route.
7. Counterpoints and Caveats
- 適格 is fact-specific: the qualified tests are technical and the NTA publishes individual-inquiry response examples (照会事例) precisely because edge cases are common. Always confirm 適格 status per transaction.
- Cash-out 株式交換 invites scrutiny: using cash consideration to force out a minority can trigger appraisal litigation and fairness-opinion expectations comparable to a squeeze-out.
- Cross-border limits: like 株式交付, 株式交換 / 株式移転 are designed for Japanese stock companies; cross-border share-swaps generally route through the structures in cross-border M&A Japan rather than these domestic regimes.
- HoldCo formation is a multi-tool decision: 株式移転 is only one of three HoldCo-formation methods; the trade-offs against the 会社分割 “抜け殻” route are in holding-company conversion.
