UnitedHealth Group CEO Stephen J. Hemsley had a total compensation of $28.14 million last year, according to documents filed Wednesday with the U.S. Securities and Exchange Commission.

The year before, Hemsley's compensation was $34.72 million.

His 2013 compensation included $1.3 million in salary, $3.1 million in non-equity incentive plan pay, $173,254 in "other compensation," $9.48 million in value realized on exercising options, and $14.09 million in value realized on vesting stock.

Separately, Hemsley was given stock awards valued at $5.63 million when they were distributed last year, which will provide value in the future. The ultimate value depends on the company's performance in the future.

The Courant tallies executive compensation to reflect the amount received within a given year, which includes salary, bonus, non-equity incentive pay, other compensation, options exercised and stock vested. It does not include the value of option awards and stock awards distributed that year, which will provide value in the future. It also does not include contributions to an executive's pension or other deferred compensation.

Chief Financial Officer David S. Wichmann was compensated a total of $12.64 million, not including stock award valued at $3.38 million when they were distributed. The stock awards will provide value in the future.
