The following table summarizes the number of individuals served by our UnitedHealthcare businesses, by major market segment and funding arrangement:
## Table 0 ##
In the commercial group market, broad-based growth was across group sizes and regions, led by gains in services to small groups and resulted in the overall increase in people served through risk-based benefit plans.
Fee-based commercial group business declined due to the non-renewal of one public sector customer.
Membership in individual business decreased due to our reduced participation in ACA-compliant products in 2017.
Medicare Advantage increased year-over-year due to growth in people served through individual and employer-sponsored group Medicare Advantage plans.
Medicaid growth was driven by the combination of new state-based awards and growth in established programs.
Medicare Supplement growth reflected strong customer retention and new sales.
UnitedHealthcare’s revenue increase was due to growth in the number of individuals served across its businesses and price increases for underlying medical cost trends, which were partially offset by the reduction of people served in ACA-compliant individual products and the impact of the Health Insurance Industry Tax moratorium.
The increase in UnitedHealthcare’s earnings from operations was led by diversified growth and increased operating margin.
The 2016 results included losses in ACA-complaint individual products and guaranty fund assessments.

general corporate use), $28.4 billion of debt securities and $2.0 billion of investments in equity securities consisting of investments in non-U.
S.  dollar fixed-income funds; employee savings plan related investments; and dividend paying stocks.
Given the significant portion of our portfolio held in cash equivalents, we do not anticipate fluctuations in the aggregate fair value of our financial assets to have a material impact on our liquidity or capital position.
Other sources of liquidity, primarily from operating cash flows and our commercial paper program, which is supported by our bank credit facilities, reduce the need to sell investments during adverse market conditions.
See Note 4 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements” for further detail concerning our fair value measurements.
Our available-for-sale debt portfolio had a weighted-average duration of 3.2 years and a weighted-average credit rating of “Double A” as of December 31, 2017.
When multiple credit ratings are available for an individual security, the average of the available ratings is used to determine the weighted-average credit rating.
Capital Resources and Uses of Liquidity In addition to cash flows from operations and cash and cash equivalent balances available for general corporate use, our capital resources and uses of liquidity are as follows: Commercial Paper and Bank Credit Facilities.
Our revolving bank credit facilities provide liquidity support for our commercial paper borrowing program, which facilitates the private placement of senior unsecured debt through third-party broker-dealers, and are available for general corporate purposes.
For more information on our commercial paper and bank credit facilities, see Note 8 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements.
” Our revolving bank credit facilities contain various covenants, including covenants requiring us to maintain a defined debt to debt-plus-shareholders’ equity ratio of not more than 55%.
As of December 31, 2017, our debt to debt-plus-shareholders’ equity ratio, as defined and calculated under the credit facilities, was approximately 37%.
Long-Term Debt.
Periodically, we access capital markets to issue long-term debt for general corporate purposes, such as, to meet our working capital requirements, to refinance debt, to finance acquisitions or for share repurchases.
For more information on our debt, see Note 8 of Notes to the Consolidated Financial Statements included in Part II, Item 8 “Financial Statements.
” Credit Ratings.
Our credit ratings as of December 31, 2017 were as follows:
## Table 1 ##
(a) In January 2018, S&P Global affirmed our ratings and changed our outlook to Stable.
The availability of financing in the form of debt or equity is influenced by many factors, including our profitability, operating cash flows, debt levels, credit ratings, debt covenants and other contractual restrictions, regulatory requirements and economic and market conditions.
For example, a significant downgrade in our credit ratings or adverse conditions in the capital markets may increase the cost of borrowing for us or limit our access to capital.
Share Repurchase Program.
As of December 31, 2017, we had Board authorization to purchase up to 42 million shares of our common stock.
For more information on our share repurchase program, see Note 10 of Notes to the Consolidated Financial Statements included in Part II, Item 8, “Financial Statements.
” Dividends.
In June 2017, our Board increased our quarterly cash dividend to shareholders by 20% to an annual dividend rate of $3.00 per share.

The following table provides details of the Company’s redeemable noncontrolling interests’ activity for the years ended December 31, 2017 and 2016:
## Table 2 ##
Share-Based Compensation The Company recognizes compensation expense for share-based awards, including stock options, stock-settled stock appreciation rights (SARs) and restricted stock and restricted stock units (collectively, restricted shares), on a straight-line basis over the related service period (generally the vesting period) of the award, or to an employee’s eligible retirement date under the award agreement, if earlier.
Restricted shares vest ratably, primarily over two to five years and compensation expense related to restricted shares is based on the share price on date of grant.
Stock options and SARs vest ratably primarily over four years and may be exercised up to 10 years from the date of grant.
Compensation expense related to stock options and SARs is based on the fair value at date of grant, which is estimated on the date of grant using a binomial option-pricing model.
Under the Company’s Employee Stock Purchase Plan (ESPP), eligible employees are allowed to purchase the Company’s stock at a discounted price, which is 85% of the lower market price of the Company’s common stock at the beginning or at the end of the six-month purchase period.
Share-based compensation expense for all programs is recognized in operating costs in the Consolidated Statements of Operations.
Net Earnings Per Common Share The Company computes basic earnings per common share attributable to UnitedHealth Group common shareholders by dividing net earnings attributable to UnitedHealth Group common shareholders by the weightedaverage number of common shares outstanding during the period.
The Company determines diluted net earnings per common share attributable to UnitedHealth Group common shareholders using the weighted-average number of common shares outstanding during the period, adjusted for potentially dilutive shares associated with stock options, SARs, restricted shares and the ESPP (collectively, common stock equivalents), using the treasury stock method.
The treasury stock method assumes a hypothetical issuance of shares to settle the share-based awards, with the assumed proceeds used to purchase common stock at the average market price for the period.
Assumed proceeds include the amount the employee must pay upon exercise and any unrecognized compensation cost.
The difference between the number of shares assumed issued and number of shares assumed purchased represents the dilutive shares.
