From Due Diligence Findings to Contract Protection in a Bulgarian Business Acquisition

A due diligence report is useful when the buyer can see what must happen next. Each material finding should lead to a decision: resolve it before completion, allocate the financial risk, change the price or structure, or reconsider the transaction.

This guide follows the overview of legal due diligence in Bulgarian M&A. It explains how the findings can inform negotiations. The appropriate response depends on the structure, governing law, evidence and bargaining position; there is no clause that makes every risk acceptable.

1. Turn the report into a decision list

For each significant issue, record the underlying fact, the missing evidence, the consequence for the business and the proposed response. Assign someone to resolve it and a date by which it must be resolved. Distinguish a confirmed liability from an uncertainty that still needs investigation.

A missing document may be a filing gap or evidence of a fundamental ownership problem. The response should follow the actual consequence. A business that depends on a particular operating permission cannot be assessed in the same way as one with a minor administrative omission.

Illustrative findings and possible responses
FindingPossible transaction response
A key contract requires consent to a change of controlObtain the required written consent before completion and check its conditions.
An identified historical claim may produce a future paymentInvestigate exposure; negotiate a specific reimbursement obligation and realistic payment protection.
Working capital differs from the price assumptionsAgree a defined adjustment mechanism with the financial advisers.
A pledged asset is essential to the businessAgree repayment and effective release steps, with completion evidence.
Necessary operating rights cannot be securedRevisit the structure, timing or commercial case before committing.

2. Use conditions for matters that must be resolved first

A condition to completion identifies something that must happen before the buyer is obliged to complete. Examples include a third-party consent, a release of security or receipt of a required regulatory approval. Describe the evidence of satisfaction, who must obtain it and what happens if it is not available by the agreed final date.

Check merger control, foreign investment screening and sector-specific approvals at the structuring stage. Applicable approval requirements cannot be removed by agreement between buyer and seller. The Competition Protection Commission and InvestBulgaria Agency provide official starting points for the relevant screening.

If a requirement can lawfully be waived, identify who may waive it and the consequences. A buyer should understand the residual exposure before accepting a promise to fix a material issue after the seller has received the price.

3. Reflect the findings in the price and payment arrangements

Some issues are best reflected directly in the economics. Unpaid debts, owner balances, uncertain receivables and unusual working capital need coordinated legal, financial and tax review. Define the price assumptions, accounting policies, calculation date and dispute procedure.

A price reduction compensates for the agreed valuation effect; it does not itself release a mortgage, preserve a licence or secure a supplier’s cooperation. Keep those requirements separate. Specify how shareholder loans, intra-group balances and transaction costs will be treated, so the same item is not counted twice or left outside the calculation.

Where money is retained or held in escrow, agree who holds it, when it can be released, what a claim must contain and how a dispute affects release. Confirm that the proposed bank or escrow provider will operate the arrangement before making it central to the deal.

4. Distinguish factual assurances from specific risk allocation

Warranties record agreed assurances about the company or assets. Their value depends on their wording, the disclosure process, the remedy and the seller’s ability to meet a claim. A statement that the business complies with all laws may be heavily qualified by disclosed information and other contractual limits.

For an identified risk, consider a specific payment or reimbursement obligation. State which event triggers it, which losses are covered, who receives payment, what evidence is needed and who controls any third-party dispute. Explain the relationship with insurance, tax benefits, other recoveries and any prohibition on double recovery.

English expressions such as “warranty” and “indemnity” do not determine the result under Bulgarian law. The operative obligations and remedies need to be drafted for the chosen governing law and mandatory rules. Article 94 of the Obligations and Contracts Act, for example, prevents advance exclusion or limitation of liability for intentional conduct or gross negligence.

5. Make disclosure usable and preserve the evidence

Agree how the seller discloses exceptions to the assurances. Identify the documents, relevant facts and version of the disclosure materials. A large data room may contain information without making its significance clear. The contract should explain what counts as effective disclosure and how the buyer’s knowledge affects claims.

Preserve an agreed copy of the transaction documents and disclosure materials at completion. Keep the final due diligence questions and written answers. If a dispute arises later, the parties need to establish what was disclosed and what was agreed, rather than reconstruct a changing online folder.

6. Check whether a claim could actually be recovered

A promise from a seller with no remaining assets may have little practical value. Assess the counterparty, any guarantor, proposed security, enforcement forum and location of assets. Where a guarantee or security is used, confirm the provider’s authority and the steps required for validity and effectiveness.

Review claim notices, monetary thresholds, caps and exclusions together. Distinguish contractual notice machinery from statutory limitation periods. Article 113 of the Obligations and Contracts Act prohibits agreements shortening or extending statutory prescription periods; an imported “survival period” needs careful analysis of what it is intended to do.

7. Carry the protection through completion and beyond

Prepare a completion checklist connecting each condition and payment to the required document, filing or confirmation. For an OOD share acquisition, local transfer formalities and registration steps remain relevant even when the commercial terms appear in a separate acquisition agreement.

After completion, assign responsibility for outstanding undertakings, price calculations, retained amounts and claim notices. A risk allocation provision is only useful if someone monitors the facts and deadlines needed to invoke it. The first 100 days guide turns these commitments into an operating plan.

Frequently asked

Does a warranty remove an existing liability?

No. It may provide a contractual remedy if its requirements are met. An underlying liability, third-party right or regulatory requirement needs its own treatment.

Should every finding become a condition to completion?

No. Prioritise matters that must be resolved before the buyer takes the risk. Other issues may justify a price adjustment, a specific payment obligation, further investigation or a documented action after completion.
