When converting registered share capital and participation interests from BGN to EUR, rounding is where otherwise straightforward math can turn into a filing problem. A few euro cents of mismatch between the converted capital and the sum of the converted participation interests may be enough to trigger instructions from the Bulgarian Commercial Register or delay unrelated corporate changes.

Bulgarian law addresses this practical issue by allowing a limited technical adjustment of the converted share capital—within a margin of up to 5%—so that the figures reconcile while shareholders’ rights and proportions remain unchanged.

Why the problem arises: a classic rounding example

Consider a limited liability company (OOD) with share capital of BGN 100. After conversion, the capital becomes EUR 51.13. If the company has 10 participation interests of BGN 10 each, each interest converts to EUR 5.11. However, 10 × 5.11 = EUR 51.10—leaving a discrepancy of EUR 0.03 between the converted capital and the sum of the converted interests.

What a “5% adjustment” is—and what it is not

The 5% adjustment is not a loophole. It is a statutory mechanism designed to “smooth out” rounding differences that occur during euro conversion. The purpose is to change the currency, not the ownership structure. Any adjustment must preserve shareholders’ rights and the proportional participation of each shareholder.

When you may need the adjustment

Typical indicators include:

• After conversion and rounding, the total of the participation interests does not equal the converted share capital.
• Nominal values become impractical (e.g., EUR 5.11) and create friction for future transfers or internal accounting.
• The company has many shareholders or uneven percentages, where small rounding differences accumulate.
• You want to keep a practical structure (e.g., 10, 100, or 1,000 participation interests) rather than moving to very large counts.
• You anticipate near-term changes (transfer of interests, admission of a new shareholder, changes in management) and want to avoid delays caused by discrepancies.

What can be adjusted within the 5% margin

In practice, companies typically use one or a combination of the following tools, provided that the shareholders’ proportional rights remain unchanged:

• Adjust the converted share capital up or down (within up to 5% of the registered capital).
• Change the nominal value of one participation interest to avoid awkward decimals.
• Change the number of participation interests (e.g., moving to a EUR 0.01 nominal value).
• Restructure the figures so that: number of interests × nominal value = share capital.

Three practical approaches

A) Many interests, perfect arithmetic

If the nominal value is set at EUR 0.01, the number of interests can match the share capital in euro cents. For EUR 51.13, that would be 5,113 interests. This removes residual amounts, but increases the administrative burden and transaction documentation.

B) Keep the number of interests, adjust the capital (most common)

If the company wants to keep a “human” number of interests (e.g., 10, 100, 1,000), it may adjust the converted capital within the 5% margin so the figures close. In the example above, keeping 10 interests of EUR 5.11 implies capital of EUR 51.10. If the difference remains within the allowed range, this approach keeps the structure simple and practical.

C) Move to a simpler capital figure and redistribute cleanly

Sometimes the cleanest solution is to round the converted capital to a nearby amount (still within the 5% limit) and set a convenient nominal value and number of interests, while preserving the same ownership proportions. The best approach depends on the number of shareholders and how often changes are made.

“Without a standard capital procedure” — what this really means

This phrase is often misunderstood. It means that, where the adjustment is solely a technical consequence of euro conversion and remains within the permitted margin, the company does not have to follow the full set of steps typically required for a capital increase or decrease under the Bulgarian Commercial Act.

However, it does not mean “without documents.” The company still needs the proper corporate resolution and a correctly amended constitutive act for publication.

Implementation steps (practical checklist)

1. Check the converted share capital as shown on the company’s register file and compare it to the current constitutive act (still in BGN).
2. Convert participation interests and confirm whether their sum reconciles with the converted capital after rounding.
3. Select an approach (A/B/C) that preserves proportional rights and produces workable figures.
4. Confirm the proposed capital adjustment (if any) is within the permitted 5% margin.
5. Prepare amendments to the Articles/Memorandum: capital in EUR, number and nominal value of interests, and allocation among shareholders.
6. Adopt the relevant corporate resolution (General Meeting / sole owner). In practice, a 3/4 majority is commonly required for such amendments.
7. Prepare a certified copy signed by the legal representative and file it for publication with the Commercial Register.
8. Monitor for instructions and ensure no unnecessary personal data is included in documents intended for publication.

Common pitfalls that lead to instructions

• Unintentional change of ownership percentages when restructuring interests.
• Mismatch between the corporate resolution and the amended constitutive act.
• Adjustment beyond the permitted 5% margin.
• Improper certification/signature of the copy submitted for publication.
• Including unnecessary personal data in documents filed for publication (the register file is public).

Why legal counsel is often advisable

These matters combine corporate law formalities with numerical precision. The goal is a structure that is lawful, internally consistent, and resilient for future transactions—without delaying other planned filings. Legal counsel typically helps by verifying that proportional rights are preserved, selecting the most risk‑free approach, and preparing a filing package that is less likely to receive instructions.
