Norwegian seismic survey ship operator EMGS has revealed it has $2.1m deposited with a Mexican bank that has been closed down by the country's government.
Banco Accendo, known as the country's "fintech" lender, had its licence revoked earlier this month due to falling capitalisation levels.
The bank has now gone into liquidation.
EMGS said its funds are no longer "immediately available".
The company added that it hopes to recover at least part of the $2.1m
