In clinic M&A (mergers and acquisitions) and business succession, addressing the needs of the staff working on the front lines is as important as, or even more important than, the change in management. Healthcare institutions are composed of diverse human resources, including not only doctors but also nurses, administrative staff, technicians, and more. It is no exaggeration to say that issues surrounding staff treatment after M&A hold the key to smooth business continuity. For both the selling (transferor) and buying (transferee) parties, how staff employment, salary structures, benefits, and working conditions are succeeded is one of the most keenly watched matters. This article explains the basic principles of staff treatment in medical M&A, specific succession practices, and the process leading to agreement between both parties, from an expert’s perspective.
In particular, when issues specific to medical corporations, such as changes in members (shareholders) or the return of funds, are involved, the impact can extend to staff treatment. Furthermore, the perspective of how external factors like medical fee revisions and changes in facility standards affect post-M&A organizational management and staff compensation is also important. M&A Medical (operated by CentralMedience Inc.), as an M&A support institution certified by the Small and Medium Enterprise Agency, has supported numerous M&A and business succession cases for medical institutions. Through this article, we aim to resolve your doubts and concerns regarding post-M&A staff treatment and contribute to the realization of smooth succession.
Basic Principles of Staff Treatment in M&A
In clinic M&A, especially in cases of stock transfer or equity transfer, the corporate status is generally inherited as is. Therefore, existing employment contracts typically continue between the corporation and the staff. This means that M&A does not immediately terminate staff employment contracts. However, depending on the buyer’s management policy or reorganization plans, there is a possibility that salary structures, bonuses, allowances, and even working hours and holidays may be reviewed. For the seller, it is important to negotiate so that these conditions are not significantly altered to maintain staff motivation and ensure a smooth handover.
On the other hand, in the case of business transfer, the buyer selects the staff necessary for the business to be transferred and concludes new employment contracts. In this scenario, existing employment contracts are terminated with the seller, and new contracts are concluded with the buyer, making changes in terms and conditions more likely. The impact on staff treatment differs depending on which scheme is chosen. M&A Medical supports optimal scheme proposals tailored to your situation and intentions, as well as negotiations regarding staff treatment associated with them.
1. Succession of Employment Contracts: Differences by Scheme
The method of succeeding staff employment contracts varies significantly depending on the M&A scheme. Understanding this is crucial from the early stages of M&A negotiations.
Stock Transfer / Equity Transfer
Maintenance of Corporate Identity
- ✅ Employment contracts continue as is between the corporation and staff.
- ✅ Staff maintain their legal status and rights.
- ✅ Salaries, bonuses, benefits, and working conditions are generally succeeded.
- ✅ However, changes may occur depending on the buyer’s intentions (explained later).
Business Transfer
Conclusion of Individual Contracts
- ✅ Employment contracts with the seller are generally terminated.
- ✅ The buyer concludes new contracts with individually hired staff.
- ✅ The buyer can select the staff to be hired based on their judgment.
- ✅ As new contracts are concluded, changes in salary and conditions are likely.
In stock transfers and equity transfers, from a legal perspective, existing employment contracts are succeeded as they are, making it the most reassuring scheme for staff. However, it is entirely possible that the buyer may consider revising salary structures or reorganizing personnel after a certain period for management efficiency or organizational integration. Therefore, including clauses in the SPA (Stock Purchase Agreement / Business Transfer Agreement) such as “maintain current salary levels for a certain period (e.g., 6 months to 1 year)” or “maintain current benefits” becomes an important negotiation point for the seller.
On the other hand, in a business transfer, the buyer voluntarily hires staff, so the seller’s concern is whether the staff’s employment can be secured. The buyer will likely want to secure the personnel necessary for business continuity while applying their own employment rules. In this case, the seller needs to negotiate to secure the continued employment of key staff. Furthermore, if the seller has a retirement benefit system, its settlement or succession must be clarified in the business transfer negotiations.
2. Succession and Adjustment of Salaries, Bonuses, and Allowances
The most direct impact on staff treatment after M&A is financial compensation such as salaries, bonuses, and various allowances. While the buyer generally integrates staff into their own salary system, staff compensation from the seller may change during this process.
Succession of Salary Structure
Generally, the buyer’s salary structure will apply. If the seller’s salary level is higher than the buyer’s, there is a possibility of reduction. Conversely, the same applies if the buyer’s salary level is lower. Regarding this point, the seller can prevent a sudden deterioration in treatment by establishing a clause in the SPA such as “maintain current salary levels for X months.” As a guideline, maintaining the current level for at least 3 to 6 months after the M&A completion is considered desirable to prevent confusion among staff.
Handling of Bonuses and Lump-Sum Payments
The handling of bonuses varies depending on the timing of the M&A execution. For example, bonuses that accrued before the M&A completion (where the calculation period is complete but payment has not yet occurred) are generally the responsibility of the seller. Bonuses paid after completion are at the discretion of the buyer, but it is important to pre-determine this in the SPA.
Various Allowances and Incentives
Various allowances such as position allowances, qualification allowances, commuting allowances, housing allowances, as well as incentive systems, are generally reviewed according to the buyer’s regulations. In particular, when incentives based on the volume of medical fees exist, careful consideration is required for their succession or transition to a new system. If the buyer is a medical corporation that is less affected by medical fee revisions or has a stable revenue base, the abolition or modification of incentive systems can significantly impact staff motivation.
【Important】Points to Note Regarding Salary and Bonus Succession
Guideline: It is common to include a clause to maintain salary levels for at least 3-6 months after M&A completion. Regarding bonuses, the party responsible changes depending on the M&A execution timing, making clear agreements in the SPA essential.
3. Succession of Benefits and Working Conditions
Along with salaries and bonuses, benefits and working conditions significantly impact staff satisfaction and retention rates. These are also important considerations for post-M&A treatment.
Succession of Benefits
Statutory benefits such as health insurance, employees’ pension insurance, employment insurance, and workers’ accident compensation insurance generally continue as long as the corporate status is inherited. However, non-statutory benefits, such as housing subsidies, family allowances, company trips, condolence and congratulatory money, retirement benefit systems, training programs, and health check-up subsidies, may be changed according to the buyer’s regulations.
In particular, the retirement benefit system requires detailed provisions in the SPA regarding its succession method (continuation of the current system, transition to a new contribution system, lump-sum payment, etc.) and the treatment of associated liabilities (retirement benefit obligations). If the seller has retirement benefit obligations, whether to transfer these to the buyer or to settle/liquidate them before the M&A execution is a critical issue that affects the feasibility and sale price of the M&A.
Succession of Working Conditions
Working hours, break times, holidays, leave (paid leave, special leave, etc.), and rules of conduct are generally succeeded as they are. However, if the buyer has stricter working hour management or introduces its own leave system, changes may occur. In particular, with the advancement of reforms for physician working hours, the management of working hours tends to become even more stringent. Whether the buyer has already established a system to cope with these reforms also affects the working conditions of the staff.
Revision of Work Rules
The buyer generally intends to apply their own work rules after the M&A. In such cases, if the staff’s working conditions are unfavorably changed, agreement with the labor representative (or labor union) and explanation to employees are required based on the Labor Standards Act. The seller needs to pay attention to this process to ensure that staff rights are not unjustly infringed.
4. Treatment of Retirement Benefits and Retirement Benefit Obligations
The existence of a retirement benefit system and its succession is one of the key issues in M&A. In particular, if retirement benefit obligations are recorded on the seller’s balance sheet, failure to clarify how they will be handled can make M&A execution difficult.
Succession of Retirement Benefit System
If the seller has established its own retirement benefit system, the question arises whether the buyer will continue that system after the M&A. If the buyer transitions to its own retirement benefit system (or defined contribution pension, iDeCo, etc.), detailed arrangements are necessary regarding how to guarantee the years of service and contribution amounts accumulated by the seller’s staff. Generally, the amount equivalent to retirement benefits based on years of service up to the M&A execution date will be paid as a lump sum, or it will be succeeded into the buyer’s new system.
Treatment of Retirement Benefit Obligations
Retirement benefit obligations are estimates of the total amount of retirement benefits and pensions to be paid to employees in the future. If these are recorded as liabilities on the seller’s balance sheet, it is important to clarify how these obligations will be handled before the M&A execution. The options include, but are not limited to, the following:
- Settlement/Liquidation by the Seller: Before M&A execution, the seller repays the retirement benefit obligations with its assets, making the liabilities zero.
- Succession to the Buyer: The buyer assumes the retirement benefit obligations and prepares for future payments. In this case, the amount of the obligation is considered in the calculation of the purchase price.
- Partial Succession / Partial Settlement: Flexible arrangements are also possible, such as the buyer assuming obligations for staff with X or more years of service, while the seller settles the rest.
The treatment of retirement benefit obligations affects the M&A execution price and the tax treatment for both the seller and the buyer, so it must be handled carefully in cooperation with experts (tax accountants, certified public accountants). M&A Medical’s experienced team of experts provides support for such complex liability treatments.
5. Reaching Agreement with Labor Unions / Employee Representatives
Some medical institutions may have established labor unions or elected employee representatives. Changes in staff treatment due to M&A require appropriate procedures to be followed with these organizations or representatives.
Negotiations with Labor Unions
If a labor union exists, collective bargaining with the labor union may be required by labor agreements or labor laws regarding the transfer of management rights due to M&A and subsequent changes in employment conditions. The buyer must reach an agreement with the union regarding employment continuation, maintenance/improvement of working conditions, and other treatment. The seller is also expected to maintain good relations with the union and cooperate in smooth information sharing.
Consultation with Employee Representatives / Information Sessions
Even if there is no labor union, employee representatives may be elected. In such cases, it is advisable to consult with employee representatives regarding changes to work rules or working conditions. Furthermore, holding employee information sessions to explain the M&A overview, future outlook, and impact on staff is highly effective in alleviating staff anxiety and maintaining organizational unity.
Importance of Information Disclosure
In the M&A process, careful judgment is required regarding the extent of information to be disclosed to staff. However, for important changes related to employment and treatment, providing explanations as early and as thoroughly as possible is crucial to prevent confusion due to speculation and maintain trust. M&A Medical provides professional advice and support for these negotiations and the operation of information sessions.
