# Dieter Berninghaus: consultancy and the disputed EUR 16.7m

**Question.** Why is the EUR 16.7 million payment to Berninghaus’s circle disputed?

**Answer.** The payment was structured as a loan; Berninghaus says it paid for selling part of his investment, while Benko and investigators describe a loan.

## Adviser and indirect investor

- Analysis: The retained account says Dieter Berninghaus joined Signa after leaving Migros in 2016 and acted through a consultancy contract without an operational office. From 2017 an Obwalden company attributed to his wife had an investment agreement with Familie Benko Privatstiftung. He left Signa in May 2023 for health reasons. This indirect contractual exposure is distinct from a personally registered stake in the foundation. [s-d263]
- Attributed: Retained reporting says Berninghaus joined Signa after leaving Migros in 2016, acted through a consultancy rather than an operational office, and left in May 2023 for health reasons. From 2017 a company of his wife in Obwalden had an investment agreement with Familie Benko Privatstiftung. The EUR 16.7 million payment accompanied his 2022 consultancy renewal and exercise of some put options. [s-d263]
  - Qualification: The contractual indirect investment is not a direct shareholding by Berninghaus personally in the foundation.
  - Response: Berninghaus said the payment was a share-sale price and denied the suggestion that a house purchase caused it; Benko described it as a loan.

## Payment chain and competing accounts

- Analysis: The retained Swiss-letter account traces EUR 16.7 million in May 2022 from Signa to Vienna’s Sarpis Holding, then on the same day to an Obwalden company, and eventually to a property company buying a house in Küsnacht. It attributes the companies in the chain to Berninghaus’s wife. The shorthand Signa does not by itself identify the exact group company that made the first payment. [s-d263]
- Attributed: The retained account traces a EUR 16.7 million May 2022 payment from Signa to Vienna’s Sarpis Holding, then the same day to a company in Obwalden and subsequently to a property company purchasing a house in Küsnacht. The reported Swiss letter attributes the companies to Dieter Berninghaus’s wife. [s-d263]
  - Qualification: The competing contractual explanations remain unresolved here. SIGNA Holding must not be assumed to be the precise paying entity from the shorthand Signa without separate evidence.
  - Response: Berninghaus repeatedly rejected wrongdoing and said this was payment for selling part of his Signa interest, with loan structuring decided by Benko. Benko maintained that it was a loan; WKStA suspected an economically unjustifiable loan.
- Analysis: WKStA suspected an economically unjustifiable loan. Berninghaus repeatedly denied wrongdoing and said he had sold part of his Signa investment through put options linked to his consultancy renewal. He said Benko alone decided to structure the payment as a loan and rejected the suggestion that a house purchase was its reason. Benko maintained that it was a loan. The retained account acknowledges a loan contract but does not resolve these competing explanations. [s-d263]

## Swiss information, Austrian investigation

- Analysis: Swiss federal prosecutors reportedly alerted WKStA in July 2025 after three banks notified MROS in spring of three accounts with seven-figure balances potentially connected with Austrian offenses. The Swiss authority was not conducting its own case and offered assistance if Austria requested it. Bank reporting and cross-border notification establish the investigative information flow, rather than a conviction or proof that every account balance came from crime. [s-d263]
