In the M&A and business succession of medical institutions, the “Representations and Warranties” clauses included in the final agreement (SPA) hold extremely significant meaning for both the seller and the buyer. The healthcare industry, in particular, has unique regulations and customs different from general corporations, such as the medical fee reimbursement system, various licenses, and complex accounting standards for medical corporations. Therefore, careful examination of the scope and content of representations and warranties is essential. This article provides a detailed explanation from the basic concepts of representations and warranties in medical M&A to tax risks, and specific points that accountants and tax accountants should confirm.
Basic Concepts of Representations and Warranties and Their Importance in Medical M&A
Representations and Warranties are clauses in M&A transactions where the seller promises the buyer that the current status of the target medical corporation or clinic (financial condition, legal compliance status, presence of licenses, contractual relationships, etc.) is true and accurate at a specific point in time. The main purpose of these clauses is to correct information asymmetry and to clarify the location of potential future risks, assigning responsibility for them.
In medical M&A, their importance is further heightened. For example, medical corporations are highly public-interest entities contributing to regional healthcare, and strict legal compliance is required in their operations. If issues such as fraudulent claims for medical fees, failure to meet facility standards, problems related to the equity interests of medical corporations, or the existence of off-balance-sheet liabilities are discovered after M&A, the buyer may face not only significant financial losses but also serious consequences such as administrative sanctions and loss of social credibility. Therefore, it is essential for the buyer to secure a legal basis to pursue the seller’s responsibility through representations and warranties for potential risks that could not be fully investigated during due diligence (DD).
Furthermore, in the case of medical corporations with equity interests, the appropriateness of procedures related to changes in members or the transfer of equity interests, and the existence and appropriateness of repayment obligations for funds in fund-contribution-type medical corporations, are also important subjects of representations and warranties. It is no exaggeration to say that how these issues specific to medical corporation types are incorporated into representations and warranties can determine the success or failure of the M&A.
Key Items of Representations and Warranties Particularly Emphasized in Medical M&A
Representations and warranties in medical M&A need to cover a wider range of items than in general corporate M&A. Below are the key items that are particularly emphasized and their specific issues in the healthcare industry.
- Financial Matters: Basic items include the accuracy of financial statements, the absence of off-balance-sheet liabilities, the presence or absence of unpaid overtime, and the appropriateness of provisions for retirement benefits. For medical corporations, special liabilities such as loan relationships with the director, appropriateness of related-party transactions, lease liabilities for medical equipment, and medical waste disposal costs also need to be confirmed. For medical corporations with equity interests, the accuracy of net assets is particularly important as it forms the basis for evaluating the equity interests.
- Tax Matters: The accuracy of past tax returns, the status of tax audits, and the absence of future additional tax liabilities are questioned. Specific issues for medical corporations include the appropriateness of the tax classification between insured medical care and private medical care for consumption tax, compliance with the requirements for non-taxable provisions and preferential measures for business tax, and the maintainability of tax preferential measures for specific medical corporations and social medical corporations. For the succession of individual clinics, the taxation of capital gains and the tax implications of transferring membership interests in medical corporations also need to be confirmed.
- Medical Fee Reimbursement Matters: The accuracy of medical fee claims is one of the most critical items in medical M&A. This can include the history of individual guidance and audits by the regional bureau, the presence or absence of fraudulent claims, the status of notification and compliance with facility standards, the accuracy of claims for the past five years, and even the response to future medical fee revisions and their impact on revenue.
- Labor Matters: While the status of employment contracts and work rules, compliance with labor laws, and the absence of unpaid overtime are similar to general M&A, the risk of unpaid overtime tends to be particularly high due to the specialized nature of managing working hours for professionals such as doctors and nurses. Social insurance enrollment is also important as it is mandatory for medical corporations.
- Licenses and Legal Compliance: Confirmation includes the validity of clinic establishment permits and insurance medical institution designations, and the status of notification for various facility standards, as well as strict compliance with medical-related laws such as the Medical Care Act, the Medical Practitioners Act, and the Pharmaceuticals and Medical Devices Act, including permits for handling narcotics, radiation, and management systems for specific medical devices. The system for protecting patient personal information is also a confirmation item.
- Litigation and Medical Accidents: Pending litigation, the occurrence of past medical accidents, the history of patient complaints, and the coverage of medical malpractice insurance are confirmed.
- Equity Interests, Member Changes, and Fund Repayments: For medical corporations with equity interests, representations and warranties regarding the lawful procedures for transferring equity interests, approval status at general meetings of members, and the valuation of equity interests are required. For medical corporations without equity interests, representations and warranties also cover the existence of fund repayment obligations, the appropriateness of repayment conditions, and the transparency of member change procedures.
Designing Compensation Clauses for Representations and Warranties Breaches and Specific Considerations in Medical M&A
Compensation clauses stipulate what compensation the seller will provide to the buyer in the event of a breach of representations and warranties. The design of these clauses is extremely important for risk management, and the following points need to be considered in medical M&A.
- Scope of Compensation: In addition to breaches of representations and warranties, “special compensation matters” may be established for specific events occurring after the M&A agreement is concluded, or for potential risks that could not be identified during due diligence. For example, this could include repayment orders for past fraudulent claims for medical fees discovered after M&A, or the risk of cancellation of insurance medical institution designation due to administrative sanctions.
- Compensation Cap: The cap is often set at a certain percentage of the transaction price (generally around 50-100%), but it can vary significantly depending on the magnitude of the risk and bargaining power.
- Compensation Floor (Basket, Deductible): To prevent frequent claims for small amounts, a “deductible” (under which damages below a certain amount are not compensated) or a “basket clause” (under which compensation is provided only when cumulative damages exceed a certain amount) is established. For example, settings such as less than 500,000 yen for individual cases and less than 5,000,000 yen cumulatively are seen, but this also varies by case.
- Compensation Period: The period varies depending on the content of the representations and warranties. General matters are typically around 1-2 years, but tax-related matters are generally set for 5-7 years, aligned with the statute of limitations for tax audits (generally 5 years, 7 years in cases of fraud). Matters related to medical fee reimbursement are also generally set for about 5 years, aligned with the look-back period (generally 5 years). Labor-related matters are often around 2-3 years.
- Utilization of Representations and Warranties Insurance (W&I Insurance): In recent years, W&I (Warranty & Indemnity) insurance, which covers compensation risks due to breaches of representations and warranties, has become widespread. By having the buyer take out this insurance, it is expected to limit the seller’s compensation liability and promote smooth M&A.
- Escrow Account: A mechanism where a portion of the transaction price is deposited with a third-party institution (escrow account) for a certain period, and compensation is made from it in case of a breach of representations and warranties, is also effective.
Relationship Between Tax Risks and Representations and Warranties in Medical M&A
Tax risks in medical M&A are very significant as potential liabilities, and are items that require particularly detailed examination within the representations and warranties clauses. Accountants and tax accountants need to deeply investigate and confirm the following points.
- Accuracy of Past Tax Returns: Scrutinize whether all tax filings, including corporate tax, consumption tax, business tax, and withholding tax, comply with laws and regulations. Errors in the classification of consumption tax (private medical care vs. insured medical care, taxable purchases of medicines and medical devices, non-taxable purchases) particularly carry the risk of leading to substantial additional tax assessments.
- Treatment of Business Tax: Business tax for medical corporations is generally non-taxable for insured medical care revenue, but taxable for private medical care revenue. Confirm whether this classification is appropriately made, and whether preferential measures under the Local Tax Act and non-taxable provisions for specific medical corporations and social medical corporations are correctly applied.
- Corporate Tax Issues: Confirm whether expenses such as entertainment expenses, executive compensation (excessive executive compensation), depreciation expenses, and bad debt provisions are appropriately accounted for. Particularly, excessive executive compensation to the director or the booking of entertainment expenses without substance are items that are easily denied in tax audits.
- Capital Gains Taxation: In the case of succession of an individual clinic (business transfer), confirm the valuation of transferred assets (medical equipment, interior, goodwill, etc.) and the appropriateness of capital gains tax on them. In the case of transferring equity interests in a medical corporation, confirm the legal basis for capital gains taxation (or non-taxation) on the difference between the valuation of the equity interests and the transfer price.
- Tax Risks as Off-Balance-Sheet Liabilities: Identify tax risks that have been pointed out in past tax audits or may be pointed out in the future, and these should be recognized as off-balance-sheet liabilities and be subject to representations and warranties. In some cases, the establishment of provisions for such risks may be considered.
- Regional Medical Care Planning and Tax Incentives: If subsidies or tax incentives related to regional medical care planning have been received, guarantee compliance with the requirements and confirm that there is no risk of failing to meet the requirements after M&A.
These tax risks can significantly impact the business plan after M&A, making it essential to clearly define the scope, period, and specific details of compensation in the wording of the representations and warranties.
Role of Accountants and Tax Accountants in Medical M&A
Due to the expertise and complexity involved, the role of accountants and tax accountants in representations and warranties for medical M&A is extremely important. Professionals support both sellers and buyers through a wide range of services, including the following:
- Conducting Financial and Tax Due Diligence: Thoroughly examine financial statements, tax returns, various contracts, and accounting books to identify potential risks (off-balance-sheet liabilities, unpaid overtime, tax issues, etc.). In particular, delve deeply into the accuracy of medical fee claims, compliance with facility standards, and accounting treatments unique to medical corporations (director loans, funds, etc.).
- Reviewing Wording of Representations and Warranties Clauses and Supporting Negotiations: Based on the risks identified through DD, scrutinize whether the wording of the representations and warranties clauses accurately reflects the reality and provides adequate risk hedging for the buyer. Support negotiations on clarifying the scope of warranties related to compliance with laws unique to the healthcare industry, such as the Medical Care Act, the Pharmaceuticals and Medical Devices Act, and medical fee-related regulations, as well as compensation periods and compensation caps/floors.
- Evaluating Tax Risks and Considering Provisions: Quantify past tax risks (e.g., incorrect consumption tax classification, erroneous application of business tax) and consider the establishment of compensation provisions or reflection in price negotiations for potential additional tax liabilities that may arise after M&A. Also, analyze the tax implications for the seller’s capital gains tax and the buyer’s acquisition costs.
- Providing Advice Based on Medical Corporation Type: Understand the tax and legal characteristics of each type of medical corporation (medical corporations with equity interests, medical corporations without equity interests (fund-contribution type, specific medical corporations, social medical corporations, etc.)) and provide expert advice on the necessity of representations and warranties related to procedures such as member changes, valuation of equity interests, and fund repayments, and their impact on the M&A scheme.
- Supporting Post-M&A Tax and Accounting Treatment: Continue to support the buyer in smoothly operating the business after M&A, including tax filings under the new organizational structure, accounting treatment, and the establishment of a tax compliance system.
Through these specialized knowledge and experiences, accountants and tax accountants play a crucial role in ensuring that representations and warranties in medical M&A function as effective risk management tools, rather than mere formal clauses.
