TMK (Specified-Purpose Company) special-purpose-company mechanics

TL;DR

TMK — Tokutei Mokuteki Kaisha (特定目的会社, Specified-Purpose Company) is the statutory securitization vehicle under Japan’s Act on Securitization of Assets (資産流動化法, 1998) — the regulated SPV form designed specifically for asset-backed securities issuance. Unlike the TK-GK private-placement workhorse, TMK is governed by a dedicated statute rather than the general Companies Act, requires an asset liquidation plan (資産流動化計画) filed with regulators, and can issue specified bonds (特定社債), specified short-term bonds, and preferred contributions (優先出資) publicly to investors. The distinctive tax treatment is the structural feature that makes TMK the preferred vehicle for many listed CMBS, certain large-scale real-estate securitization deals, and complex multi-tranche structures: profit distributions to investors are deductible at the TMK level, achieving effective single-layer taxation if statutory distribution requirements are met (typically 90%+ of distributable profit).

For FinWiki, TMK is the regulated-statutory-SPV node in the Japan securitization landscape. The choice between TMK and GK-TK is the foundational securitization-vehicle-choice decision for arrangers — TMK for public-bond issuance, regulatory-disclosure deals, listed CMBS, complex structures; GK-TK for private-placement, flexible-bilateral deals, faster-formation private real-estate securitization. TMK is also a distinct vehicle from the J-REIT market overview — both are tax-pass-through real-estate vehicles but operate under different statutes (Asset Securitization Act vs Investment Trust Act).

1. Legal basis — Act on Securitization of Assets

Item	TMK statutory basis
Statute	Act on Securitization of Assets (資産流動化法, 1998; amended multiple times)
Successor to	The 1998 SPC Act, expanded over time to cover wider asset classes
Regulatory authority	FSA (formation registration, asset liquidation plan filing, ongoing supervision)
Vehicle name	Tokutei Mokuteki Kaisha (TMK, 特定目的会社, Specified-Purpose Company)
Statutory purpose	Asset securitization (statutorily restricted purpose — TMK cannot engage in general business activities outside securitization)
Asset liquidation plan	Required filing — describes assets to be securitized, expected cash flows, securities to be issued, redistribution mechanism

The statutory restriction on activities is a key feature: TMK’s bankruptcy-remote character comes partly from the statutory limitation that prevents the TMK from incurring liabilities outside its asset-securitization purpose.

2. Issuance instruments

TMK can issue several types of securities to investors:

Instrument	Description
Specified bonds (特定社債)	Senior debt; can be publicly placed; covered by the asset liquidation plan
Specified short-term bonds (特定短期社債)	Short-tenor debt under the same regime
Preferred contributions (優先出資)	Equity-like; investors receive preferred distribution rights; tax-pass-through (if statutory conditions met)
Common contributions (普通出資)	Subordinated equity; typically held by originator or B-piece investor
Specified loans	TMK can also borrow under the asset liquidation plan

The combination of specified bonds (senior debt) and preferred contributions (mezzanine/equity tranches) enables multi-tranche capital-structure that mirrors international securitization conventions.

3. Tax treatment — the distinctive feature

Element	TMK tax treatment
Corporate income tax	TMK is a corporation; subject to corporate tax in principle
Distribution deductibility	Distributions to preferred contributors and specified-bond holders (interest) are deductible at TMK level
Effective pass-through	If distribution exceeds 90%+ of distributable profit (statutory condition), residual taxable income at TMK is minimal — effective single-layer taxation
Statutory conditions for pass-through	Public-offering / qualified-institutional-investor offering conditions, distribution-ratio condition, asset-management restriction conditions
Comparison to GK-TK	GK-TK achieves pass-through via TK overlay; TMK achieves pass-through via direct distribution deductibility
Comparison to J-REIT	J-REIT (investment corporation) achieves pass-through via similar 90% distribution rule under Investment Trust Act
Withholding tax	Distributions to investors may be subject to withholding depending on investor classification

The distribution deductibility mechanism makes TMK behave economically like a pass-through vehicle while remaining a corporation legally. This is the cleanest pass-through mechanism for public-bond issuance.

4. Comparison with GK-TK

| Dimension | TMK | GK-TK | |---|---|---| | Statutory basis | Act on Securitization of Assets | Companies Act (GK) + Commercial Code (TK) | | Formation | Asset liquidation plan filing; FSA-registered | Simpler — incorporate GK, sign TK contracts | | Public bond issuance | Yes — specified bonds publicly placeable | Limited — typically private placement | | Equity tranching | Yes — preferred + common contributions | TK-overlay provides pass-through to multiple TK investors | | Tax pass-through | Distribution deductibility at TMK level | TK-distribution deductibility at GK level | | Activity restriction | Statutorily restricted to securitization purpose | GK statutorily flexible; TK purpose set by contract | | Bankruptcy remoteness | Strong — statutory and contractual layers | Contractual only | | Typical use | Public-bond CMBS, large/complex deals, listed-securities deals | Private real-estate securitization, bilateral deals, faster-formation private placements | | Speed of formation | Slower (asset liquidation plan filing) | Faster | | Disclosure burden | Higher (FSA registration + ongoing disclosure) | Lower (private-placement disclosure regime) |

5. TMK in current J-REIT structure

A common confusion is the relationship between TMK and J-REIT. Both are tax-pass-through real-estate vehicles but operate under different statutes:

Vehicle	Statute	Form
TMK	Asset Securitization Act	Specified-Purpose Company (corporation)
**[[real-estate-finance/j-reit-market-overview	J-REIT investment corporation]]**	Investment Trust Act (投資信託法)

In current J-REIT practice, TMK is sometimes used at the sub-vehicle level:

Use case	Description
J-REIT acquires TMK preferred contributions	Some J-REIT hold TMK preferred contributions rather than direct real-estate ownership, particularly for tax-efficient structuring of certain asset classes
Sponsor-side TMK as warehouse	Sponsors may use TMK to warehouse stabilized assets before J-REIT acquisition
TMK for non-J-REIT-eligible assets	Asset classes that don’t fit J-REIT criteria may be held in TMK structures by institutional investors
TMK for foreign-investor real-estate	Some foreign-LP real-estate investments use TMK structures for tax / withholding treatment

The TMK-J-REIT interaction is important for understanding the broader Japanese real-estate-vehicle ecosystem; TMK is a building block that can sit inside or alongside J-REIT investment corporations.

6. TMK in listed CMBS

TMK CMBS feature	Reading
Issuer entity	TMK (specified-purpose company under Asset Securitization Act)
Issuance	Specified bonds publicly placed; tranched by seniority
Collateral	Commercial real-estate-backed mortgage loan(s) or trust beneficial interests in commercial real estate
Asset liquidation plan	Filed with FSA; sets out asset-cash-flow distribution mechanics
Rating	Domestic agency ([[financial-regulators/jcr
Investor base	Life insurers, asset managers, megabank ALM books, foreign institutional investors
Servicer / trustee	Trust bank or specialty servicer roles

TMK is the dominant structure for single-borrower listed CMBS in Japan (the post-2008 CMBS form per Japan CMBS issuance structure). The combination of public-bond issuance capability and tax-pass-through makes TMK the natural choice for listed-tranched CMBS deals.

7. TMK governance and ongoing obligations

Obligation	Description
Asset liquidation plan compliance	Activities restricted to those described in the asset liquidation plan
Director composition	TMK has directors with statutory role; typically independent professional directors
Auditor	Statutory auditor or audit corporation
Ongoing disclosure	Periodic reporting on asset performance and bond status to investors and FSA
Distribution mechanics	Distributions per the asset liquidation plan; statutory tax-pass-through conditions
Wind-down	TMK winds down when assets are fully amortized or sold
