In an advertisement in a business daily on May 8, 2015, the company had claimed itself to be the number one in India.
The advertisement read: "Star Health Insurance ranks No. 1 among all private general and health insurance companies in India in health segment (2014-15)."
The Insurance Regulatory and Development Authority of India (IRDAI) said it reviewed the ad and found it in violation of an IRDAI circular.
The IRDAI circular of 2007 says: "No claim of ranking by an insurance company as regards its position in the insurance market based on any criteria (like premium income or number of policies or branches or claims settlements etc) is permissible in any of the advertisements."
"In light of the above, your company is hereby warned for the above violations. You are directed to comply with the provisions of advertisement regulations, guidelines and circulars issued by the Authority while releasing insurance advertisements," IRDAI said.
