Citigroup Inc. said it has discovered another alleged fraud by a second company in Mexico, identified in news reports as Representaciones y Distribuciones EVYA.
EVYA, an engineering and construction firm, is a supplier to Mexican state-owned oil company Petróleos Mexicanos, or Pemex.
It specializes in helipads for offshore oil and gas facilities.
Citibank CFO John Gerspach said on a media call Monday the alleged fraud was under $30 million and the bank expects full restitution.
In February, the government of Mexico took control of another Pemex supplier, Oceanografia.
The action followed allegations by Citibank of an alleged $400 million fraud.
New York-based Citigroup said in March a review of loans to Oceanografia showed that the company had actually posted only $185 million in collateral and not the $585 million the bank had relied on.
Citibank said Oceanografia had allegedly submitted nearly $400 million of fraudulent invoices for short-term credit that were processed by a bank employee.
The chief executive of Oceanografía, Amado Yáñez Osuna, is under house arrest in Mexico.
Mexico’s police are also questioning an employee of Citibank’s Mexico unit, Banco Nacional de Mexico, or Banamex, Mexico’s second-biggest bank.
The U.S. Securities and Exchange Commission is also reported to be investigating accounting fraud at Citibank Mexico.
Citigroup was forced to reduce 2013 profit by $235 million because of Oceanografia’s alleged fraud.
