The process of settlement of relations with the lessor AerCap (Ireland) for 18 aircraft and 5 aircraft engines operated by Aeroflot Group companies has been completed.

Ireland-based AerCap in a stock market filing said it had received $645 million from insurance company NSK in full settlement of insurance claims in relation to 17 aircraft and 5 spare engines leased to state-controlled airline Aeroflot and its subsidiary Rossiya.

The planes would now become the property of Russian state-owned NSK.

"We have released our claims against NSK, Aeroflot, Rossiya and their international reinsurers with respect to these aircraft and engines," said AerCap, whose shares rose around 5% in premarket trading.

Aeroflot Group continues negotiations on the settlement of existing claims with other lessors of foreign-made aircraft.
