Interglobe aviation (indigo) vs USD

Today when i am studying about interglobe aviation services they are dedicating some losses to appreciation of USD as they took some loans overseas.
1.Where can we track their debts?
As the USDINR fluctuations making them bleed heavily
2. I’m getting to a conclusion that it’s better to avoid companies who has debt outside i wrong in any way?
