Humana Reports Third Quarter Financial Results

Humana Reports Third Quarter Financial Results

November 1, 2010 at 6:02 AM EDT
  • EPS for 3Q10 of $2.32 included $0.31 of favorable prior-period medical claims development
  • 2010 EPS guidance raised to $6.40 to $6.50
  • Strong operating performance in both business segments
  • YTD cash flows from operations exceeded $2.2 billion
  • TRICARE contract expected to be extended through March 2012

LOUISVILLE, Ky., Nov 01, 2010 (BUSINESS WIRE) --

Humana Inc. (NYSE: HUM) today reported diluted earnings per common share (EPS) for the quarter ended September 30, 2010 (3Q10) of $2.32, ahead of management's guidance of $1.65 to $1.75. The company earned $1.78 per share for the quarter ended September 30, 2009 (3Q09). Results for 3Q10 reflect improved performance in the company's operations, the beneficial effect of $0.21 per share in higher-than-expected favorable medical claims development related to prior years(a) and $0.10 per share in higher-than-expected favorable medical claims development related to the first half of 2010(a).

For the nine months ended September 30, 2010 (YTD10) the company reported $5.84 in EPS compared to $4.67 in EPS for the nine months ended September 30, 2009 (YTD09). Results for YTD10 reflect improved performance in the company's operations and the beneficial effect of $0.72 per share in higher-than-expected favorable medical claims development related to prior years(a), partially offset by $0.55 per share in expenses from the write-down of certain deferred acquisition costs in the second quarter 2010.

"Our third-quarter results showed strong operating performance in both our Government and Commercial segments," said Michael B. McCallister, Humana's chairman of the board and chief executive officer. "With the success of our one-to-one retail approach to membership growth solidly aligned with the continued expansion of Medicare and potential retail opportunities in the individual market, Humana faces the post-reform future with confidence."

The company now anticipates EPS of approximately $6.40 to $6.50 for the year ending December 31, 2010 (FY10) reflecting the improved operating performance and the expectation of a TRICARE contract extension, as discussed below.

Humana plans to issue its 2011 earnings guidance in conjunction with its biennial investor meeting scheduled for November 18, 2010. That meeting will be available to the media and general public via a live web cast.

TRICARE Update

As previously disclosed by the company, on October 5, 2010, Humana Military Healthcare Services, Inc. (HMHS), a wholly-owned subsidiary of the company, was notified by the United States Department of Defense TRICARE Management Activity (TMA) that the TMA intends to negotiate with HMHS for an extension of HMHS's administration of the TRICARE program South Region contract for an additional option period from April 1, 2011 through March 31, 2012.

Discussions are still at a preliminary stage, but Humana no longer anticipates incurring the previously expected expenses of between $0.19 and $0.28 per diluted common share during FY10 related to the previously anticipated loss of the TRICARE contract on March 31, 2011. Such expenses may, however, be incurred in future periods, depending on the ultimate disposition of future contract awards, as discussed in the company's Securities and Exchange Commission filings.

Consolidated Highlights

Revenues - 3Q10 consolidated revenues rose 9 percent to $8.42 billion from $7.72 billion in 3Q09, with total premium and administrative services fees also up 9 percent compared to the prior year's quarter. The year-over-year increase in premiums and administrative services fees primarily reflects a 17 percent increase in average membership for the company's Medicare Advantage plans and continued pricing discipline across all of the company's lines of business, partially offset by lower average stand-alone Prescription Drug Plan (PDP) and commercial fully-insured group medical membership.

Consolidated revenues for YTD10 rose 9 percent to $25.52 billion from $23.33 billion for YTD09 with total premiums and administrative services fees up 9 percent compared to the prior year's period, also driven primarily by the same factors as the third quarter year-over-year increase.

Benefit expenses - The 3Q10 consolidated benefit ratio (benefit expenses as a percent of premium revenues) of 81.6 percent decreased 50 basis points from 82.1 percent for the prior year's quarter and included a 100 basis point beneficial effect of higher-than-expected favorable prior-period medical claims development in 3Q10 (a). The Commercial Segment benefit ratio for 3Q10 improved 350 basis points while that for the Government Segment increased 30 basis points year over year. The primary drivers of these changes are detailed in the segment discussions below.

The consolidated benefit ratio for YTD10 of 82.3 percent was 80 basis points lower than the YTD09 consolidated benefit ratio of 83.1 percent due primarily to an 80 basis point beneficial effect of higher-than-expected favorable prior-year medical claims development YTD10 (a). The lower consolidated benefit ratio versus the prior year's period included a 390 basis point improvement in the benefit ratio for the Commercial Segment and a 20 basis point improvement for the Government Segment. These changes were primarily driven by the same factors impacting the third quarter year-over-year comparisons.

Selling, general, & administrative (SG&A) expenses - The 3Q10 consolidated SG&A expense ratio (SG&A expenses as a percent of premiums, administrative services fees and other revenue) of 12.9 percent decreased 80 basis points from the 3Q09 ratio of 13.7 percent reflecting both scale efficiencies associated with higher average Medicare Advantage membership and the company's continued focus on administrative cost reductions.

The YTD10 consolidated SG&A expense ratio of 13.3 percent decreased 20 basis points from the YTD09 ratio of 13.5 percent primarily reflecting the same factors impacting the third quarter year-over-year comparison, partially offset by the impact of the write-down of certain deferred acquisition costs in the second quarter of 2010.

Government Segment Results

Pretax results:

  • Government Segment pretax income increased to $554.1 million in 3Q10 from $474.5 million in 3Q09 primarily due to higher average Medicare Advantage membership year-over-year and a lower SG&A expense ratio. The lower SG&A expense ratio resulted from economies of scale associated with higher average membership and a continued focus on administrative cost reductions.
  • For YTD10, pretax earnings for the Government Segment of $1.36 billion increased by $316.4 million versus YTD09 pretax earnings for the segment of $1.05 billion, primarily reflecting the same factors as those affecting the quarterly year-over-year comparisons.

Enrollment:

  • Medicare Advantage membership grew to 1,764,800 at September 30, 2010, an increase of 250,000 members, or 17 percent, from 1,514,800 at September 30, 2009, and up 256,300, or 17 percent, versus 1,508,500 at December 31, 2009. As of September 30, 2010, approximately 74 percent of the company's fully-insured Medicare Advantage members were in network-based products versus 62 percent at September 30, 2009 and 63 percent at December 31, 2009.
  • Membership in the company's stand-alone PDPs totaled 1,785,600 at September 30, 2010 compared to 1,960,400 at September 30, 2009 and 1,927,900 at December 31, 2009. Both the year-over-year and year-to-date membership declines resulted primarily from attrition due to the company's competitive positioning as it realigned stand-alone PDP premium and benefit designs to correspond with its pharmacy claims experience.
  • Military services membership at September 30, 2010 of 3,031,100 was essentially unchanged from 3,015,100 at September 30, 2009 and 3,034,400 at December 31, 2009.

Premiums and administrative services fees:

  • Medicare Advantage premiums of $4.80 billion in 3Q10 increased 16 percent compared to $4.14 billion in 3Q09, primarily the result of a 17 percent increase in average Medicare Advantage membership.
  • Medicare stand-alone PDP premiums of $579.6 million in 3Q10 were up slightly compared to $578.1 million in 3Q09, reflecting the generally offsetting impacts of a 10 percent increase in premiums per member per month and a 9 percent decline in average membership year over year.
  • Military services premiums and administrative services fees during 3Q10 increased $77.0 million, or 9 percent, to $895.8 million compared to $818.8 million in 3Q09.

Benefit Expenses:

  • The Government Segment benefit ratio of 82.2 percent increased 30 basis points versus the 3Q09 ratio of 81.9 percent primarily due to an increase in Medicare Advantage group business (which generally carries a higher benefit ratio than the company's individual Medicare Advantage business). The segment's benefit ratio for 3Q10 also included the beneficial effect of 100 basis points from higher-than-expected favorable prior-period medical claims development(a), 70 basis points related to the prior year and 30 basis points related to the first half of 2010.

SG&A Expenses:

  • The Government Segment's SG&A expense ratio of 9.5 percent decreased from 10.2 percent in 3Q09 reflecting continued scale efficiencies associated with higher average Medicare Advantage membership and a continued focus on administrative cost reductions.

Commercial Segment Results

Pretax results:

  • Commercial Segment pretax income increased to $68.1 million in 3Q10 compared to a pretax loss of $5.2 million in 3Q09 due to lower levels of health care services utilization as well as the company's continued focus on pricing discipline and administrative cost reductions.
  • For YTD10, pretax income for the Commercial Segment of $213.4 million compared to earnings of $157.8 million for YTD09 primarily reflecting the same factors as those affecting the quarterly year-over-year comparisons partially offset by $147.5 million in expenses during the second quarter of 2010 associated with the write-off of certain deferred acquisition costs.

Enrollment:

  • Commercial Segment medical membership declined to 3,130,900 at September 30, 2010, a decrease of 296,000, or 9 percent, from 3,426,900 at September 30, 2009 and a decline of 279,900, or 8 percent, from 3,410,800 at December 31, 2009. The year-over-year declines during both 3Q10 and YTD10 primarily reflected continued pricing discipline across the company's fully-insured medical lines of business.
  • Membership in Commercial Segment specialty products(b) of 7,038,800 at September 30, 2010 decreased less than 1 percent from 7,073,700 at September 30, 2009 and 1 percent from 7,109,900 at December 31, 2009.

Premiums and administrative services fees:

  • Premiums and administrative services fees for the Commercial Segment decreased 3 percent to $1.81 billion in 3Q09 compared to $1.87 billion in the prior year's quarter, reflecting an 8 percent decline in average medical membership year over year, partially offset by continued pricing discipline.
  • Commercial Segment medical premiums for fully-insured group accounts increased approximately 8 percent on a per-member basis during 3Q10 compared to 3Q09.

Benefit Expenses:

  • The Commercial Segment benefit ratio for 3Q10 of 79.2 percent was 350 basis points lower than the 3Q09 benefit ratio of 82.7 percent, primarily due to lower levels of health care services utilization year over year and continued pricing discipline. The segment's benefit ratio for 3Q10 also included the beneficial effect of 120 basis points from higher-than-expected favorable prior-period medical claims development(a), 90 basis points related to the prior year and 30 basis points related to the first half of 2010.

SG&A Expenses:

  • The Commercial SegmentSG&A expense ratio of 24.4 percent for 3Q10 compares to 24.0 percent in 3Q09, as increases in the company's specialty, ancillary and individual medical businesses that carry a higher administrative expense load as a percent of revenues were partially offset by the company's continued focus on administrative cost reductions.

Balance Sheet

  • At September 30, 2010, the company had cash, cash equivalents, and investment securities of $11.54 billion, up 12 percent from $10.29 billion in such assets at June 30, 2010. Parent company cash and investments at September 30, 2010 were $1.27 billion, up $270.4 million from $1.00 billion at June 30, 2010.
  • Debt-to-total capitalization at September 30, 2010 was 19.4 percent, down 110 basis points from 20.5 percent at June 30, 2010 due primarily to increased net income during 3Q10.

Cash Flows from Operations

Cash flows provided by operations for 3Q10 of $1.21 billion compared to cash flows provided by operations of $940.1 million in 3Q09 with the increase primarily due to higher net income and changes in working capital balances year over year.

Share Repurchase Program

In December 2009, the company's Board of Directors renewed its authorization for the use of up to $250 million for the repurchase of Humana common shares. During 3Q10, the company repurchased 968,000 of its outstanding shares at an average price per share of $51.66. As of November 1, 2010, the company had approximately $150 million remaining on the December 2009 authorization, which is effective until December 31, 2011.

Footnotes

(a)

Actuarial standards require the use of assumptions based on moderately adverse experience, which generally results in favorable reserve development, or reserves that are considered redundant. When the Company recognizes a release of the redundancy, it discloses the amount that is not in the ordinary course of business.

(b)

The Commercial Segment provides a full range of insured specialty products including dental, vision and other supplemental products. Members included in these products may not be unique to each product since members have the ability to enroll in multiple products. Other supplemental benefits include life, disability, and fixed benefit products including cancer and critical illness policies.

Cautionary Statement

This news release includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. When used in investor presentations, press releases, Securities and Exchange Commission (SEC) filings, and in oral statements made by or with the approval of one of Humana's executive officers, the words or phrases like "expects," "anticipates," "intends," "likely will result," "estimates," "projects" or variations of such words and similar expressions are intended to identify such forward-looking statements. These forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties, and assumptions, including, among other things, information set forth in the "Risk Factors" section of the company's SEC filings, a summary of which includes but is not limited to the following:

  • Recently enacted health insurance reform, including The Patient Protection and Affordable Care Act and The Health Care and Education Reconciliation Act of 2010, could have a material adverse effect on Humana's results of operations, including restricting revenue, enrollment and premium growth in certain products and market segments, increasing the company's medical and administrative costs by, among other things, requiring a minimum benefit ratio, lowering the company's Medicare payment rates and increasing the company's expenses associated with a non-deductible federal premium tax; financial position, including the company's ability to maintain the value of its goodwill; and cash flows. In addition, if the new non-deductible federal premium tax is imposed as enacted, and if Humana is unable to adjust its business model to address this new tax, there can be no assurance that the non-deductible federal premium tax would not have a material adverse effect on the company's results of operations, financial position, and cash flows.
  • If Humana does not design and price its products properly and competitively, if the premiums Humana charges are insufficient to cover the cost of health care services delivered to its members, or if its estimates of benefit expenses are inadequate, Humana's profitability could be materially adversely affected. Humana estimates the costs of its benefit expense payments, and designs and prices its products accordingly, using actuarial methods and assumptions based upon, among other relevant factors, claim payment patterns, medical cost inflation, and historical developments such as claim inventory levels and claim receipt patterns. These estimates, however, involve extensive judgment, and have considerable inherent variability that is extremely sensitive to payment patterns and medical cost trends.
  • If Humana fails to effectively implement its operational and strategic initiatives, including its Medicare initiatives, the company's business may be materially adversely affected, which is of particular importance given the concentration of the company's revenues in the Medicare business.
  • If Humana fails to properly maintain the integrity of its data, to strategically implement new information systems, or to protect Humana's proprietary rights to its systems, the company's business may be materially adversely affected.
  • Humana is involved in various legal actions, which, if resolved unfavorably to Humana, could result in substantial monetary damages. Increased litigation and negative publicity could increase the company's cost of doing business.
  • Humana's business activities are subject to substantial government regulation. New laws or regulations, or changes in existing laws or regulations or their manner of application, could increase the company's cost of doing business and may adversely affect the company's business, profitability and financial condition. In addition, as a government contractor, Humana is exposed to additional risks that may adversely affect the company's business or the company's willingness to participate in government health care programs.
  • On October 5, 2010, Humana was notified that the Department of Defense TRICARE Management Activity intends to negotiate with Humana for an extension of Humana's administration of the TRICARE South Region contract, comprised of a one-year option period from April 1, 2011 through March 31, 2012. As a result, Humana no longer expects that an impairment of certain assets associated with its military services business, primarily consisting of goodwill, will occur during 2010. There can be no assurance, however, that the contract will be extended.
  • Any failure to manage administrative costs could hamper Humana's profitability.
  • Any failure by Humana to manage acquisitions and other significant transactions successfully may have a material adverse effect on its results of operations, financial position, and cash flows.
  • If Humana fails to develop and maintain satisfactory relationships with the providers of care to its members, the company's business may be adversely affected.
  • Humana's mail order pharmacy business is highly competitive and subjects it to regulations in addition to those the company faces with its core health benefits businesses.
  • Changes in the prescription drug industry pricing benchmarks may adversely affect Humana's financial performance.
  • If Humana does not continue to earn and retain purchase discounts and volume rebates from pharmaceutical manufacturers at current levels, Humana's gross margins may decline.
  • Humana's ability to obtain funds from its subsidiaries is restricted by state insurance regulations.
  • Downgrades in Humana's debt ratings, should they occur, may adversely affect its business, results of operations, and financial condition.
  • Changes in economic conditions could adversely affect Humana's business and results of operations.
  • The securities and credit markets may experience volatility and disruption, which may adversely affect Humana's business.
  • Given the current economic climate, Humana's stock and the stock of other companies in the insurance industry may be increasingly subject to stock price and trading volume volatility.

In making forward-looking statements, Humana is not undertaking to address or update them in future filings or communications regarding its business or results. In light of these risks, uncertainties, and assumptions, the forward-looking events discussed herein may or may not occur. There also may be other risks that the company is unable to predict at this time. Any of these risks and uncertainties may cause actual results to differ materially from the results discussed in the forward-looking statements.

Humana advises investors to read the following documents as filed by the company with the SEC for further discussion both of the risks it faces and its historical performance:

  • Form 10-K for the year ended December 31, 2009;
  • Form 10-Q for the quarters ended March 31, 2010 and June 30, 2010;
  • Form 8-Ks filed during 2010.

Footnotes to Statistical Schedules and Supplementary Information

3Q10 Earnings Release

(A)

The selling, general and administrative (SG&A) expense ratio is defined as SG&A expenses as a percent of premiums, administrative services fees and other revenue.

(B)

Other supplemental benefits include life, disability, and fixed benefit products including cancer and critical illness policies.

(C)

Computed based on average membership for the period (i.e., monthly ending membership during the period divided by the number of months in the period).

(D)

Military services revenues are generally not contracted on a per-member basis.

(E)

Includes administrative services fees associated with Medicare and Medicaid, operations in the United Kingdom, and, for 2009, fees associated with Green Ribbon Health.

(F)

In a limited number of circumstances, the company contracts with hospitals and physicians to accept financial risk for a defined set of HMO membership. In transferring this risk, the company prepays these providers a monthly fixed-fee per member to coordinate substantially all of the medical care for their capitated HMO membership, including some health benefit administrative functions and claims processing. For these capitated HMO arrangements, the company generally agrees to reimbursement rates that target a benefit expense ratio. Providers participating in hospital-based capitated HMO arrangements generally receive a monthly payment for all of the services within their system for their HMO membership. Providers participating in physician-based capitated HMO arrangements generally have subcontracted specialist physicians and are responsible for reimbursing such physicians and hospitals for services rendered to their HMO membership.

(G)

In some circumstances, the company contracts with physicians under risk-sharing arrangements whereby physicians have assumed some level of risk for all or a portion of the benefit expenses of their HMO membership. Although these arrangements do include capitation payments for services rendered, the company processes substantially all of the claims under these arrangements.

(H)

Duration is the time-weighted average of the present value of the bond portfolio cash flows.

(I)

IBNR represents an estimate of benefit expenses payable for claims incurred but not reported (IBNR) at the balance sheet date. The level of IBNR is primarily impacted by membership levels, benefit claim trends and the receipt cycle time, which represents the length of time between when a claim is initially incurred and when the claim form is received (i.e. a shorter time span results in lower reserves for claims IBNR). Other benefits payable includes amounts payable to providers under capitation arrangements.

(J)

Unprocessed claim inventories represent the estimated valuation of claims received but not yet fully processed.

(K)

Processed claim inventories represent the estimated valuation of processed claims that are in the post-claim-adjudication process, which consists of administrative functions such as audit and check batching and handling.

(L)

The balance due to the company's pharmacy benefit administrator fluctuates as a result of the number of business days in the last payment cycle of the month. Payment cycles are every 10 days (10th & 20th of month) and the last day of the month.

(M)

Military services benefits payable primarily consist of IBNR and to a lesser extent risk share payables to the Department of Defense and liabilities to subcontractors.

(N)

The table excludes activity associated with military services benefits payable, because the federal government bears a substantial portion of the risk associated with financing the cost of health benefits. More specifically, the risk-sharing provisions of the military services contracts with the federal government and with subcontractors effectively limit profits and losses when actual claim experience varies from the targeted claim amount negotiated annually. As a result of these contract provisions, the impact of changes in estimates for prior year military services benefits payable are substantially offset by the associated changes in estimates of revenue from health care services reimbursements. As such, any impact on the company's results of operations is reduced substantially, whether positive or negative.

(O)

Amounts incurred related to prior years vary from previously estimated liabilities as the claims ultimately are settled. Negative amounts reported for incurred related to prior years result from claims being ultimately settled for amounts less than originally estimated (favorable development). There were no changes in the approach used to determine the company's estimate of claim reserves during the quarter.

(P)

Future policy benefit expense has a related liability classified as a long-term liability on the balance sheet.

(Q)

Benefits reserves statistics represents fully-insured medical claims data and excludes military services claims data and specialty benefits.

(R)

The receipt cycle time measures the average length of time between when a claim was initially incurred and when the claim form was received. Receipt cycle time data for the company's largest claim processing platforms represent approximately 96% of the company's fully-insured claims volume. Pharmacy and specialty claims, including dental, vision and other supplemental benefits, are excluded from this measurement.

(S)

A common metric for monitoring benefits payable levels relative to the benefit expense is days in claims payable, or DCP, which represents the benefits payable at the end of the period divided by average benefit expenses per day in the quarterly period. Since the company has some providers under capitation payment arrangements (which do not require a benefits payable IBNR reserve), the company has also summarized this metric excluding capitation expense. In addition, this calculation excludes the impact of the company's military services and stand-alone PDP business.

(T)

DCP fluctuates due to a number of issues, the more significant of which are detailed in this rollforward. Growth in certain product lines can also impact DCP for the quarter since a provision for claims would not have been recorded for members that had not yet enrolled earlier in the quarter, yet those members would have a provision and corresponding reserve recorded upon enrollment later in the quarter. This analysis excludes the impact of military services and Medicare stand-alone PDPs upon DCP.
