In Q1 of 2020, it had to make an additional provision of INR 107,444 million (USD 1.45 billion) related to the matter of the Supreme Court ruling with regards to the Adjusted Gross Revenue (AGR) on license fees and spectrum usage charges. Singtel has an effective stake of 31.7 per cent in Airtel which is partly contributed by its 49.4 per cent shareholding of Bharti Telecom. It recorded a negative SGD 911 million one-off exceptional item in the quarter that ended June 2020 due to the AGR matter. Besides regional associates and Airtel, Singtel said its bottom line was buoyed by improved operating and business environment overall including better profitability at wholly owned Australian subsidiary Optus and a stronger Australian dollar. Operating revenue improved 7.7 per cent to SGD 1.7 billion from SGD 1.6 billion a year ago. On constant currency terms, revenue would have fallen 2.6 per cent.
