Turkey has started work to determine the costs of last year’s botched coup as part of a process to seek compensation, according to an official with direct knowledge of the matter, Bloomberg reported.

Muhiddin Gulal, head of the Savings Deposit Insurance Fund, known as TMSF in Turkish, sent a letter last month to all government institutions, including the army and police, to gauge the damage inflicted on buildings, equipment and vehicles during the coup attempt on July 15, 2016, which claimed more than 250 lives, an official from the TMSF said, asking not to be named in line with policy. The news of the assessment was reported earlier on Monday by Haberturk newspaper.

The fund expects to receive reports from the institutions by the end of this month, the official said. The TMSF will use legal channels to compensate for the material damage, the official said, without saying how such compensation might be made.

The TMSF has seized the assets of 1,001 companies for alleged connections to the group that the government blames for the coup, which is led by an elderly cleric who lives in the U.S., Fethullah Gulen. The TMSF assigned trustees to manage the companies, and has dropped an earlier plan to sell them.
