M&A of medical corporations is attracting attention as an important means to contribute to the continuation and development of regional healthcare. However, the process differs from M&A of general corporations and involves many complex issues unique to the healthcare industry. In particular, financial due diligence (DD) is an indispensable process for understanding the true financial status of the target medical corporation or clinic and assessing potential risks and profitability. For both the seller and the buyer, expert insight from an accountant familiar with medical M&A is required for appropriate valuation and risk hedging.
Purpose of Financial DD in Medical M&A and Healthcare Corporation-Specific Perspectives
Financial due diligence is conducted for the purpose of allowing the buyer to thoroughly investigate the financial condition of the medical corporation or clinic, verify the reasonableness of the transfer price, and provide basic information for formulating future business plans. As with general corporations, it involves understanding assets, liabilities, revenues, expenses, and cash flows through analysis of the balance sheet, income statement, and cash flow statement. However, in medical M&A, it is essential to incorporate perspectives that account for the significant impact of healthcare corporation-specific systems and regulations on financial conditions.
For example, there are two types of medical corporations: those with “capital contributions” and those without “capital contributions” (fund contribution type). Each type has different accounting treatments for changes in members and repayment of funds, as well as differences in the handling of capital gains tax. In medical corporations with capital contributions, the valuation of these contributions directly affects the M&A price, and its calculation may take into account not only net assets but also future profitability and the corporation’s position in regional healthcare plans. On the other hand, for medical corporations without capital contributions, the existence of an obligation to repay funds and the possibility of securing financial resources for such repayment can be important issues in financial DD. Furthermore, confirmation of the appropriateness of executive compensation and the tax treatment of business tax deductibility are also conducted as part of tax risk assessment.
Financial DD is typically conducted over a period of about two to three months during the main phase of the M&A process, although the duration may vary depending on the size and complexity of the target corporation. Risks and issues discovered at this stage will be reflected in the representations and warranties clauses, adjustments to the transfer price, and the PMI (Post Merger Integration) plan in the final M&A agreement.
Appropriateness of Medical Fee Claims and Profitability Assessment
Medical fee claims, which constitute the majority of revenue for medical corporations, are one of the most critical issues in financial DD due to their appropriateness. Fraudulent or erroneous claims not only pose a risk of past repayment but can also significantly impact future profitability. Specifically, the following points are examined:
- Rate of Errors, Returns, and Assessments: Analyze the occurrence and causes of medical claim errors, returns, and assessments over the past few years to evaluate the soundness of the billing system. Pay particular attention to whether there are any biases towards specific medical procedures or physicians.
- Medical Claim Review Process: Confirm the internal review system before billing, whether external outsourcing is used, and its effectiveness.
- History of Regional Bureau of Health and Welfare Individual Guidance and Audits: Understand the history of past guidance and audits, their content, and the status of improvement reports. If there is a history of guidance, it is important to confirm that subsequent corrective actions have been properly implemented.
- Risk of Fraudulent Claims: Carefully investigate signs of intentional fraudulent claims, such as excessive testing, fictitious billing, and improper insurance application. This is a serious risk that could lead to the revocation of the medical institution’s license.
- Sufficiency of Facility Standards: Confirm that the facility standards (staffing, equipment, etc.) required to claim specific medical fees are continuously met. The possibility of standards changing due to revisions in medical fee schedules must also be considered.
- Collectibility of Accounts Receivable: Confirm the collection cycle of medical fees from the Social Insurance Medical Fee Payment Fund and the National Health Insurance Federation, the status of collection for self-pay medical services, and the provision for doubtful accounts for long-outstanding receivables.
Through these evaluations, the stable revenue structure and the soundness of future medical fee claims of the target medical institution are confirmed, and the accuracy of revenue forecasts in the post-M&A business plan is improved.
Risks of Potential Off-Balance Sheet Liabilities, Contingent Liabilities, and Related Party Transactions
In medical M&A, off-balance sheet liabilities, contingent liabilities not apparent on the surface financial statements, and related party transactions can pose unexpected risks to the buyer. Thoroughly identifying these potential risks is a crucial role of financial DD.
- Off-Balance Sheet Liabilities: Thoroughly check for omissions in the recording of unpaid bonuses and retirement benefit liabilities, off-balance sheet lease liabilities (especially medical equipment leases), and contingent liabilities (medical malpractice lawsuits, employee lawsuit risks, etc.). Regarding medical accidents in particular, assess the possibility of future litigation by examining not only ongoing lawsuits but also past troubles and patient complaint histories. It is also necessary to confirm the conditions for the release of joint and several guarantee obligations of the chairman and related parties.
- Unpaid Overtime: Investigate the actual status of working hour management for doctors, nurses, medical administrative staff, etc. Examine the operational status of time cards, attendance management systems, and self-reporting, and assess the effectiveness of fixed overtime pay and the risk of unpaid overtime in the past (e.g., cases of corrective recommendations from the Labor Standards Inspection Office). This requires particular attention as long working hours are often commonplace in the healthcare industry.
- Social Insurance Enrollment Status: Confirm whether the enrollment requirements for social insurance (health insurance, employees’ pension insurance) are met not only for full-time doctors, nurses, and medical administrative staff but also for part-time workers. The risk of retroactive premiums for periods of non-enrollment may be borne by the buyer after M&A, so estimate the impact amount.
- Related Party Transactions: Thoroughly examine the existence and details of transactions between related parties, such as loan transactions between the chairman and the corporation, transactions with companies managed by the chairman’s family or relatives, and lease agreements for real estate owned by the chairman to the corporation. Evaluate whether these transactions are based on market prices, whether appropriate accounting treatment has been applied, and whether they can continue after M&A. If there are any opaque transactions, consider methods for their resolution and their impact. Real estate leases, in particular, are directly linked to business continuity after M&A, so the reasonableness of rent, contract period, and renewal conditions must be carefully confirmed.
These risks can significantly impact post-M&A business operations, so they must be accurately identified through DD and reflected in adjustments to the transfer price and contract terms.
Tax Risks and Understanding the Reality of Assets and Cash Flow
Assessing tax risks is essential to avoid unexpected tax burdens after M&A. Furthermore, the valuation of fixed assets such as medical equipment and inventory such as pharmaceuticals, as well as understanding the reality of cash flow, are important factors in measuring the financial health and future investment capacity of the target medical institution.
- Tax Risks: Check for any tax audits in the past three years, the findings, and the status of improvements. Evaluate the necessity of consumption tax payment obligations (impacted by the ratio of self-pay medical services), the appropriateness of executive compensation, and the accuracy of tax treatment for related party transactions. In particular, for M&A of medical corporations, it is necessary to consider specific tax issues such as the handling of capital gains tax on the transfer of capital contributions in medical corporations with capital contributions, and whether the medical corporation can be a target for the business succession tax system.
- Inventory (Pharmaceuticals and Consumables): Confirm the physical inventory status of pharmaceuticals and medical consumables (syringes, gauze, etc.) and verify consistency with book balances. Check for any long-term stagnant stock or expired items and evaluate whether appropriate valuation has been performed. If overvalued, it poses a risk of expense recognition after M&A.
- Fixed Assets (Medical Equipment): Confirm the operating status of major medical equipment, the appropriateness of depreciation, and the treatment of assets whose useful lives have expired. In particular, for high-value medical equipment, evaluate the status of maintenance contracts, repair history, future replacement plans, and whether these affect facility standards. For leased assets, clarify ownership and confirm the continuity and potential for changes in terms of lease agreements after M&A.
- Cash Flow: Analyze in detail the reality of operating cash flow over the past few years to identify any window dressing or abnormal values. Evaluate whether the working capital level is appropriate, whether sufficient funds can be secured for future capital investment plans and responses to regional healthcare plans (e.g., changes in bed functions or introduction of new equipment). Stable cash flow is an important indicator of stability in post-M&A business operations.
Understanding these financial realities provides indispensable information for the buyer to assess the feasibility of the post-M&A business plan.
Utilizing the Financial Due Diligence Report and Achieving Smooth M&A
The results of financial due diligence are compiled into a detailed report and have a significant impact on the final decision-making for M&A. This report includes an overview of the target medical corporation’s financial condition, key findings (risk items), and any adjustments that may affect the transfer price.
Risks identified in the report can become negotiation points for the transfer price or be reflected in the formulation of representations and warranties or indemnification clauses in the M&A agreement. For example, if the risk of unpaid overtime is identified, measures such as deducting the potential debt amount from the transfer price or explicitly stating in the contract that the seller will bear the debt after M&A may be considered. If there are doubts about the appropriateness of medical fee claims, a monitoring clause for a certain period may be established.
Medical M&A is not merely a sale and purchase of a company but also has social significance in terms of continuing and developing regional healthcare. Therefore, while confirming financial soundness through financial DD, the perspective of whether the system is in place to fulfill the social responsibilities as a medical institution may also be indirectly evaluated. Detailed financial DD by experienced accountants not only brings potential risks to light and prevents post-M&A troubles but is also an indispensable process for building a solid foundation for the buyer to safely inherit and further develop the business.
