State insurance departments and foreign jurisdictions that regulate certain of the Company's subsidiaries prescribe accounting practices (differing in some respects from GAAP) to determine statutory net income and surplus. The Company's life insurance and HMO company subsidiaries are regulated by such statutory requirements. The statutory net income of the Company's life insurance and HMO subsidiaries for the years ended, and their statutory surplus as of December 31, were as follows:

(In billions)	2015		2014		2013
Net income	$	2.1	$	2.0	$	1.6
Surplus	$	8.0	$	7.5	$	6.3

The Company's HMO and life subsidiaries are subject to minimum statutory surplus requirements and may be required to maintain investments on deposit with state departments of insurance or other regulatory bodies. Additionally, these subsidiaries may be subject to regulatory restrictions on the amount of annual dividends or other distributions (such as loans or cash advances) that insurance companies may extend to the parent company without prior approval. As of December 31, 2015, these amounts, including restricted net assets of the Company, were as follows:

(In billions)	2015
Minimum statutory surplus required by regulators	$	2.6
Investments on deposit with regulatory bodies	$	0.4
Maximum dividend distributions permitted in 2016 without state approval	$	1.5
Maximum loans to the parent company permitted without state approval	$	1.3
Restricted net assets of Cigna Corporation	$	8.6

Statutory surplus for each of the Company's life insurance and HMO subsidiaries is sufficient to meet the minimum required by regulators. For one of the Company's foreign insurance subsidiaries, the regulatory authority has permitted deferral of certain policy acquisition costs that increased statutory capital and surplus by approximately $0.2 billion as of December 31, 2015. There were no other permitted practices for the Company's insurance subsidiaries that significantly differed from prescribed regulatory accounting practices.
