Trai chairman RS Sharma said on Thursday that the task of identifying reserve price for spectrum is an \u201conerous responsibility\u201d and that there is no \u201cdefinite formula\u201d to determine it. However, some industry representatives for the first time suggested Trai that it should come out with a formula to calculate reserve price instead of the present practice of benchmarking it with the prices of the previous auctions. Such a step will lead to a scientific methodology of fixing reserve price. There are a number of factors that are relevant while looking at the reserve price for any spectrum band, Trai chief said, adding that there is no definite formula to determine it. \u201cOften these factors are difficult to quantify, but they are still relevant and are required to be considered,\u201d he added. Sharma was speaking at the open house discussion (OHD) conducted by Trai on auction of spectrum in 700 MHz, 800 MHz, 900 MHz, 1800 MHz, 2100 MHz, 2300 MHz, 2500 MHz, 3300-3400 MHz and 3400-3600 MHz bands. In April last year, the department of telecom (DoT) had requested Trai to give its recommendations on the reserve price, quantum of spectrum that is to be auctioned and other associated conditions. \u201cThe Authority has been vested with the onerous responsibility of determining the reserve price in such a manner that it does not compromise on the principles of transparency and ensure adequate participation from the industry,\u201d Sharma said. When asked by reporters on the time frame by which Trai will come out with the recommendations, he said, \u201cI cannot comment on what will be the end date. As always we will try to do it as soon as possible. It entails a lot of exercises in order to arrive at the reserve price\u201d. During the discussion, telecom operators were almost unanimous in their views and urged that the regulator should give due regard to the industry\u2019s distressed financial situation and the ongoing consolidations and exits while deciding on the timing for next round of auction. On industry\u2019s opinion that the timing is not conducive for auction, Sharma told reporters that all the aspects will be considered before a view is formed.\u00a0 When asked whether the prices during the 2016 spectrum auction were high leading to a muted response from the industry, he said, \u201cIt is difficult to come to the conclusion on what is the right price\u201d. The discussion saw participation from representatives from Bharti Airtel, Vodafone India, Idea Cellular and Reliance Jio as well as industry bodies COAI and Broadband India Forum, among others.
