Apple has agreed to submit the financials of its India business to the country's antitrust body as part of an investigation that found the U.S. firm ‌abused its market position, taking the long-delayed case a step closer to a potential penalty decision, an ‌agency order shows. The case is Apple's most high-profile regulatory headache in India, a key growth market where it has rapidly expanded iPhone production as ​it diversifies beyond China. A confidential Competition Commission of India (CCI) order, reviewed by Reuters, showed Apple last month agreed to supply its India financials - typically needed by the watchdog for penalty calculations.
