The order by the Airports Economic Regulatory Authority (AERA) will have a negative impact on the company's financials, said Siddharth Kapur, chief financial officer of GMR Infrastructure's airport business.
"We are looking at all options, including high court. There is an option of going to the appellate authority. We are also looking at going to high court. Within 30 days of the order, we will have to appeal," Kapur told reporters on the sidelines of India Aviation 2014.
The order was issued after wide consultations with all stakeholders to determine tariffs in respect of the airport for the five-year period ending March 31, 2016.
Currently, each departing domestic passenger at Hyderabad airport pays Rs 430 as user development fee, while the levy for departing international passengers is Rs 1,700 each.
"It (AERA order) will definitely have a negative impact. We will work out the numbers. It is very difficult to say the numbers at this time. In fact it (the airport) has been making profits for the last three years," Kapur said.
