KYIV, Nov 20 - Ukraine’s GDP-linked warrants issued during the debt restructuring in 2015 may potentially lead to large fiscal costs and exceed the initial debt write-off, a report from the International Monetary Fund said.

The warning adds concerns about Ukraine’s ability to be able to repay its debts next year as the IMF has withdrawn $1.4 billion in loans since June, citing slowdown of economic reforms.

GDP-linked warrants contain an element of indexation to GDP that provides holders with a higher coupon if GDP exceeds some threshold level.
