	(2)            Recent Accounting Standards
	In July 2012, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2012-02, "Intangibles—Goodwill and Other (Topic 350)—Testing Indefinite-Lived Intangible Assets for Impairment."  ASU No. 2012-02 permits an entity to perform a qualitative assessment to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value.  If the entity concludes that this is the case, it must perform the currently prescribed quantitative impairment test by comparing the fair value of the indefinite-lived intangible asset with its carrying value.  Otherwise, the quantitative impairment test is not required. ASU No. 2012-02 is effective for fiscal years beginning after September 15, 2012, with earlier adoption permitted.  We adopted this standard for the fiscal year beginning January 1, 2013.  The adoption of this standard did not have a material impact on our consolidated results of operations, financial position, cash flows, or notes to the consolidated financial statements.
	In February 2013, the FASB issued ASU No. 2013-02, "Comprehensive Income (Topic 220)—Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income," which requires companies to provide information about the amounts reclassified out of accumulated other comprehensive income ("AOCI") by component. In addition, entities are required to present, either on the face of the statement where net income is presented or in the accompanying notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, entities are required to cross-reference to other disclosures that provide additional detail on those amounts. ASU No. 2013-02 is effective prospectively for reporting periods beginning after December 15, 2012.  We adopted this standard for the interim period beginning January 1, 2013.  The adoption of this standard did not have a material impact on our consolidated results of operations, financial position, cash flows, or notes to the consolidated financial statements.

	(3)          Share-Based Compensation
	We have several stockholder-approved stock incentive plans for our employees and directors.  We currently have three types of share-based awards outstanding under these plans: stock options, restricted stock units, and restricted stock.  We believe that such awards align the interests of our employees and directors with those of our stockholders.
	For the three and nine months ended September 30, 2013, we recognized share-based compensation costs of $1.7 million and $5.2 million, respectively.  For the three and nine months ended September 30, 2012, we recognized share-based compensation costs of $1.9 million and $4.7 million, respectively.
	A summary of our stock options as of September 30, 2013 and changes during the nine months then ended is presented below:

	(4)          Income Taxes
	Despite having pre-tax income for the three months ended September 30, 2013, we had an income tax benefit of $0.7 million primarily as a result of a $1.1 million reduction to an unrecognized tax benefit due to the expiration of the applicable statutes of limitations for the 2009 tax year. This $1.1 million benefit more than offset the income tax expense for the quarter calculated using our annualized effective tax rate. For the three months ended September 30, 2012, the effective tax rate was 41.1%.
	For the nine months ended September 30, 2013, the effective tax rate was a benefit of 50.6%, which was also favorably impacted by the reduction to an unrecognized tax benefit as discussed above.  For the nine months ended September 30, 2012, the effective tax rate was 43.6%.
	We file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions.  Tax years remaining subject to examination in these major jurisdictions include 2010 to present.

	(5)          Long-Term Debt
	1.50% Cash Convertible Senior Notes Due 2018
	On July 16, 2013, we completed a private placement of $150.0 million aggregate principal amount of cash convertible senior notes due 2018 (the "Cash Convertible Notes"), which bear interest at a rate of 1.50 % per year, payable semiannually in arrears on January 1 and July 1 of each year, beginning on January 1, 2014. The Cash Convertible Notes will mature on July 1, 2018, unless earlier repurchased or converted into cash in accordance with their terms prior to such date. The Cash Convertible Notes are convertible into cash based on the conversion rate set forth below and are not convertible into our common stock or any other securities under any circumstances. The initial cash conversion rate is 51.38 shares of our common stock per $1,000 principal amount of Cash Convertible Notes (equivalent to an initial conversion price of approximately $19.46 per share of common stock). The Cash Convertible Notes are our senior unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Cash Convertible Notes. As a result of this transaction, we recognized deferred loan costs of approximately $3.9 million, which are being amortized over the term of the Cash Convertible Notes using the effective interest method.
	The cash conversion feature of the Cash Convertible Notes (the "Cash Conversion Derivative") requires bifurcation from the Cash Convertible Notes in accordance with FASB ASC Topic 815, Derivatives and Hedging, and is recorded in other long-term liabilities as a derivative liability and carried at fair value. The fair value of the Cash Conversion Derivative at the time of issuance of the Cash Convertible Notes was approximately $36.8 million, which was recorded as a debt discount for purposes of accounting for the debt component of the Cash Convertible Notes. The debt discount willl be amortized over the term of the Cash Convertible Notes using the effective interest method. For the three and nine months ended September 30, 2013, we recorded $1.5 million of interest expense related to the amortization of the debt discount based upon an effective interest rate of 5.7%.
	In connection with the issuance of the Cash Convertible Notes, we entered into privately negotiated convertible note hedge transactions (the "Cash Convertible Notes Hedges"), which are cash-settled and are intended to reduce our exposure to potential cash payments that we  would be required to make if holders elect to convert the Cash Convertible Notes at a time when our stock price exceeds the conversion price. The initial cost of the Cash Convertible Notes Hedges was approximately $36.8 million. The Cash Convertible Notes Hedges are recorded in other assets as a derivative asset under FASB ASC Topic 815 and are carried at fair value.  See Note 6 for additional information regarding the Cash Convertible Notes Hedges and the Cash Conversion Derivative and their fair values as of September 30, 2013.
	11
	In July 2013, we also sold separate privately negotiated warrants (the "Warrants") initially relating, in the aggregate, to a notional number of shares of our common stock underlying the Cash Convertible Notes Hedges. The Warrants have an initial strike price of $25.95 per share, which effectively increases the conversion price of the Cash Convertible Notes to a 60% premium to our stock price on July 1, 2013. The Warrants will be net share settled by issuing a number of shares of our common stock per Warrant corresponding to the excess of the market price per share of our common stock (as measured on each warrant exercise date under the terms of the Warrants) over the applicable strike price of the Warrants. The Warrants meet the definition of derivatives under the guidance in ASC Topic 815; however, because these instruments have been determined to be indexed to our own stock and meet the criteria for equity classification under ASC Topic 815-40, the Warrants have been accounted for as an adjustment to our additional paid-in-capital.
	If the market value per share of our common stock exceeds the strike price of the warrants, the warrants will have a dilutive effect on net income per share, and the "treasury stock" method will be used in calculating the dilutive effect on earnings per share.
	Credit Facility
	On June 8, 2012, we entered into the Fifth Amended and Restated Revolving Credit and Term Loan Agreement (the "Fifth Amended Credit Agreement"). The Fifth Amended Credit Agreement provides us with a $200.0 million revolving credit facility that expires on June 8, 2017 and includes a swingline sub facility of $20.0 million and a $75.0 million sub facility for letters of credit.  The Fifth Amended Credit Agreement also provides a $200.0 million term loan facility that matures on June 8, 2017, $140.0 million of which remained outstanding on September 30, 2013, and an uncommitted incremental accordion facility of $200.0 million.
	Borrowings under the Fifth Amended Credit Agreement generally bear interest at variable rates based on a margin or spread in excess of either (1) the one-month, two-month, three-month or six-month rate (or with the approval of affected lenders, nine-month or twelve-month rate) for Eurodollar deposits ("LIBOR") or (2) the greatest of (a) the SunTrust Bank prime lending rate, (b) the federal funds rate plus 0.50%, and (c) one-month LIBOR plus 1.00% (the "Base Rate"), as selected by the Company.  The LIBOR margin varies between 1.75% and 3.00%, and the Base Rate margin varies between 0.75% and 2.00%, depending on our leverage ratio.  The Fifth Amended Credit Agreement also provides for an annual fee ranging between 0.30% and 0.50% of the unused commitments under the revolving credit facility.  Extensions of credit under the Fifth Amended Credit Agreement are secured by guarantees from all of the Company's active domestic subsidiaries and by security interests in substantially all of the Company's and such subsidiaries' assets.
	On February 5, 2013, we entered into an amendment to the Fifth Amended Credit Agreement, which included, among other things, a temporary increase in the LIBOR and Base Rate margins of 0.25%.  The increased margins are effective through December 31, 2013 and apply only in the event that our total funded debt to EBITDA ratio is greater than or equal to 3.50 to 1.00.  On July 1, 2013, we entered into an additional amendment to the Fifth Amended Credit Agreement, which provided for, among other things, the amendment of certain negative covenants to permit the issuance of and payments related to the Cash Convertible Notes described above as well as increases in the maximum required levels of total funded debt to EBITDA beginning with the quarter ended June 30, 2013.  As of September 30, 2013, availability under the revolving credit facility totaled $57.5 million as calculated under the most restrictive covenant.
	We are required to repay outstanding revolving loans under the revolving credit facility in full on June 8, 2017. We are required to repay term loans in quarterly principal installments aggregating (1) 1.250% of the original aggregate principal amount of the term loans during each of the eight quarters beginning with the quarter ended September 30, 2012, (2) 1.875% of the original aggregate principal amount of the term loans during each of the next four quarters beginning with the quarter ending September 30, 2014, and (3) 2.500% of the original aggregate principal amount of the term loans during each of the remaining quarters prior to maturity on June 8, 2017, at which time the entire unpaid principal balance of the term loans is due and payable.
	The Fifth Amended Credit Agreement contains financial covenants that require us to maintain specified ratios or levels of (1) total funded debt to EBITDA and (2) fixed charge coverage.  As of September 30, 2013, we were in compliance with all of the financial covenant requirements of the Fifth Amended Credit Agreement.
	The Fifth Amended Credit Agreement contains various other affirmative and negative covenants that are typical for financings of this type.  Among other things, the Fifth Amended Credit Agreement limits repurchases of our common stock and the amount of dividends that we can pay to holders of our common stock.

Derivative Investments and Hedging Activities [Abstract]	'
Derivative Investments and Hedging Activities	'
	(6)          Derivative Investments and Hedging Activities
	We use derivative instruments to manage risks related to interest rate swap agreements, foreign currencies, and the Cash Convertible Notes. We account for derivatives in accordance with FASB ASC Topic 815, Derivative and Hedging, which establishes accounting and reporting standards requiring that derivative instruments be recorded on the balance sheet as either an asset or liability measured at fair value. Additionally, changes in the derivative's fair value shall be recognized currently in earnings unless specific hedge accounting criteria are met. As permitted under our master netting arrangements, the fair value amounts of our interest rate swaps and foreign currency options and/ or forward contracts are presented on a net basis by counterparty in the consolidated balance sheets.
	Derivative Instruments Designated as Hedging Instruments
	Cash Flow Hedges
	Derivative instruments that are designated and qualify as cash flow hedges are recorded at estimated fair value in the consolidated balance sheets, with the effective portion of the gains and losses being reported in accumulated other comprehensive income or loss ("accumulated OCI").  Cash flow hedges for all periods presented consist solely of interest rate swap agreements, which effectively modify our exposure to interest rate risk by converting a portion of our floating rate debt to fixed obligations, thus reducing the impact of interest rate changes on future interest expense. Under these agreements, we receive a variable rate of interest based on LIBOR (as defined in Note 5), and we pay a fixed rate of interest with interest rates ranging from 0.465% to 3.385% plus a spread (see Note 7).  We maintain interest rate swap agreements with current notional amounts of $235.0 million and termination dates ranging from November 2013 to December 2016.  Of this amount, $125.0 million was effective at September 30, 2013, $60.0 million will become effective in November 2013, and $50.0 million will become effective in 2015, as older interest rate swap agreements expire. Gains and losses on these interest rate swap agreements are reclassified to interest expense in the same period during which the hedged transaction affects earnings or the period in which all or a portion of the hedge becomes ineffective.  As of September 30, 2013, we expect to reclassify $0.6 million of net losses on interest rate swap agreements from accumulated OCI to interest expense within the next 12 months due to the scheduled payment of interest associated with our debt.
	The following table shows the effect of our cash flow hedges on the consolidated balance sheets during the three and nine months ended September 30, 2013 and 2012:
	(In $000s)	For the Three Months Ended							For the Nine Months Ended
	Derivatives in Cash Flow Hedging Relationships	30-Sep-13				30-Sep-12			30-Sep-13			30-Sep-12
	(Gain) loss related to effective portion of derivatives recognized in accumulated OCI, gross of tax effect	$	72			$	1,223		$	(624	)	$	2,001
	Loss related to effective portion of derivatives reclassified from accumulated OCI to interest expense, gross of tax effect	$	452			$	790		$	1,632		$	2,579
	Gains and losses representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings.  During the three and nine months ended September 30, 2013 and 2012, there were no gains or losses on cash flow hedges recognized in our consolidated statements of comprehensive income (loss) resulting from hedge ineffectiveness.
	Derivative Instruments Not Designated as Hedging Instruments
	Our Cash Conversion Derivative, Cash Convertible Notes Hedges, and foreign currency options and/ or forward contracts do not qualify for hedge accounting treatment under U.S. GAAP and are measured at fair value with gains and losses recognized immediately in the consolidated statements of comprehensive income (loss). These derivative instruments not designated as hedging instruments did not have a material impact on our consolidated statements of comprehensive income (loss) during the three and nine months ended September 30, 2013 and 2012.
	The Cash Conversion Derivative is accounted for as a derivative liability and carried at fair value. In order to offset the risk associated with the Cash Conversion Derivative, we entered into Cash Convertible Notes Hedges which are cash-settled and are intended to reduce our exposure to potential cash payments that we would be required to make if holders elect to convert the Cash Convertible Notes at a time when our stock price exceeds the conversion price. The Cash Convertible Notes Hedges are accounted for as a derivative asset and carried at fair value.
	The gains and losses resulting from a change in fair values of the Cash Conversion Derivative and the Cash Convertible Notes Hedges are reported in the consolidated statements of comprehensive income (loss) as follows:
		Three Months Ended			Nine Months Ended			Statements of Comprehensive Income
		30-Sep-13			30-Sep-13			(Loss) Classification
	Cash Convertible Notes Hedges:
	Net unrealized gain	$	7,341			7,341		Selling, general and administrative expenses
					$
	Cash Conversion Derivative:
	Net unrealized loss	$	(7,341	)		(7,341	)	Selling, general and administrative expenses
					$
	We also enter into foreign currency options and/or forward contracts in order to minimize our earnings exposure to fluctuations in foreign currency exchange rates.  Our foreign currency exchange contracts require current period mark-to-market accounting, with any change in fair value being recorded each period in the consolidated statements of comprehensive income in selling, general and administrative expenses. At September 30, 2013, we had forward contracts with notional amounts of $16.7 million to exchange foreign currencies, primarily the Australian dollar and Euro, that were entered into in order to hedge forecasted foreign net income (loss) and intercompany debt. We routinely monitor our foreign currency exposures to maximize the overall effectiveness of our foreign currency hedge positions.  We do not execute transactions or hold derivative financial instruments for trading or other purposes.
	The estimated gross fair values of derivative instruments at September 30, 2013 and December 31, 2012, excluding the impact of netting derivative assets and liabilities when a legally enforceable master netting agreement exists, were as follows:

Fair Value Measurements [Abstract]	'
Fair Value Measurements	'
	(7)          Fair Value Measurements
	We account for certain assets and liabilities at fair value.  Fair value is defined as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date, assuming the transaction occurs in the principal or most advantageous market for that asset or liability.
	Fair Value Hierarchy
	The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are:
	Level 1:  Quoted prices in active markets for identical assets or liabilities;
	Level 2:  Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-based valuation techniques in which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and
	Level 3:  Unobservable inputs that are supported by little or no market activity and typically reflect management's estimates of assumptions that market participants would use in pricing the asset or liability.
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	The following tables present our assets and liabilities measured at fair value on a recurring basis at September 30, 2013 and December 31, 2012:
	30-Sep-13		Level 2		Level 3		Gross Fair Value			Netting (1)			Net Fair Value
	Assets:
	Foreign currency exchange contracts		$	158	$	—	$	158		$	(78	)	$	80
	Cash Convertible Notes Hedges			—		44,091		44,091			—			44,091
	Liabilities:
	Foreign currency exchange contracts		$	115	$	—	$	115		$	(78	)	$	37
	Interest rate swap agreements			707		—		707			—			707
	Cash Conversion Derivative			—		44,091		44,091			—			44,091

	Interest rate swap agreements			2,963		2,963		—			2,963
	(1) This column reflects the impact of netting derivative assets and liabilities by counterparty when a legally enforceable master netting agreement exists.
	16
	The fair values of forward foreign currency exchange contracts are valued using broker quotations of similar assets or liabilities in active markets.  The fair values of interest rate swap agreements are primarily determined based on the present value of future cash flows using internal models and third-party pricing services with observable inputs, including interest rates, yield curves and applicable credit spreads. The fair values of the Cash Convertible Notes Hedges and the Cash Conversion Derivative are measured using Level 3 inputs. These instruments are not actively traded and are valued using an option pricing model that uses observable and unobservable market data for inputs, such as expected time to maturity of the derivative instruments, the risk-free interest rate, the expected volatility of our common stock and other factors. The Cash Convertible Notes Hedges and the Cash Conversion Derivative were designed such that changes in their fair values would offset, with minimal impact to the consolidated statements of comprehensive income (loss). Therefore, the sensitivity of changes in the unobservable inputs to the option pricing model for such instruments is largely mitigated.
	The following table presents our financial instruments measured at fair value on a recurring basis using unobservable inputs (Level 3):
			Balance at December 31, 2012		Purchases of Level 3		Issuances of Level 3 Instruments			Gains/ (Losses) included in Earnings			Balance at September 30, 2013
					Instruments
	Cash Convertible Notes Hedges		$	—	$	36,750	$	—		$	7,341		$	44,091
	Cash Conversion Derivative			—		—		(36,750	)		(7,341	)		(44,091	)
	The gains and losses included in earnings noted above represent the change in the fair value of these financial instruments and are recorded each period in the consolidated statements of comprehensive income (loss) in selling, general and administrative expenses.
	Fair Value of Other Financial Instruments
	In addition to foreign currency exchange contracts, interest rate swap agreements, the Cash Convertible Notes Hedges, and the Cash Conversion Derivative, the estimated fair values of which are disclosed above, the estimated fair value of each class of financial instruments at September 30, 2013 was as follows:
	•	Cash and cash equivalents – The carrying amount of $2.8 million approximates fair value because of the short maturity of those instruments (less than three months).
	•	Long-term debt – The estimated fair value of outstanding borrowings under the Fifth Amended Credit Agreement, which includes a revolving credit facility and a term loan facility (see Note 5), and the Cash Convertible Notes are determined based on the fair value hierarchy as discussed above.  The revolving credit facility and the term loan facility are not actively traded and therefore are classified as Level 2 valuations based on the market for similar instruments.  The estimated fair value is based on the average of the prices set by the issuing bank given current market conditions and is not necessarily indicative of the amount we could realize in a current market exchange. The estimated fair value and carrying amount of outstanding borrowings under the Fifth Amended Credit Agreement at September 30, 2013 are $142.9 million and $143.3 million, respectively.
		The Cash Convertible Notes are actively traded and therefore are classified as Level 1 valuations. The estimated fair value at September 30, 2013 was $167.6 million, which is based on the last quoted price of the Cash Convertible Notes on September 30, 2013, and the par value was $150.0 million. The carrying amount of the Cash Convertible Notes at September 30, 2013 was $114.7 million, which is net of the debt discount discussed in Note 5.

	Contract Dispute
	We currently are involved in a contractual dispute with Blue Cross Blue Shield of Minnesota regarding fees paid to us as part of a former contractual relationship.  On January 25, 2010, Blue Cross Blue Shield of Minnesota issued notice of arbitration with the American Arbitration Association in Minneapolis in accordance with the terms of the contract alleging violations of certain contract provisions and seeking recoupment of an unspecified amount of payments made to us under the contract. We believe we performed our services in compliance with the terms of our agreement and that the assertions made in the arbitration notice are without merit.  On August 3, 2011, we asserted numerous counterclaims against Blue Cross Blue Shield of Minnesota. The arbitration hearing concluded on October 23, 2013, and the parties are waiting on the arbitrator's award. We are not able to reasonably estimate a range of potential losses, if any, related to this dispute.
	Performance Award Lawsuit
	On September 4, 2012, Milton Pfeiffer ("Plaintiff"), claiming to be a stockholder of the Company, filed a putative derivative action against the Company and the Board of Directors (the "Board") in Delaware Chancery Court alleging that the Compensation Committee of the Board and the Board breached their fiduciary duties and violated the Company's 2007 Stock Incentive Plan (the "Plan") by granting Ben R. Leedle, Jr., Chief Executive Officer and President of the Company, discretionary performance awards under the Plan in the form of options to purchase an aggregate of 500,000 shares of the Company's common stock, which consisted of a performance award in November 2011 granting Mr. Leedle the right to purchase 365,000 shares and a performance award in February 2012 granting Mr. Leedle the right to purchase 135,000 shares (the "Performance Awards").  Plaintiff alleges that the Performance Awards exceeded what is authorized by the Plan and that the Company's 2012 proxy statement, in which the Performance Awards are disclosed, is false and misleading.  Plaintiff also alleges that Mr. Leedle breached his fiduciary duties and was unjustly enriched by receiving the Performance Awards.  Plaintiff is seeking, among other things, the rescission or disgorgement of all alleged "excess" awards granted to Mr. Leedle under the Performance Awards, to recover any incidental damages to the Company, and an award of attorneys' fees and expenses.  On November 2, 2012, the Company and the Board filed a Motion to Dismiss because Plaintiff failed to make a demand upon the Board as required by Delaware law.
	Outlook
	We are also subject to other contractual disputes, claims and legal proceedings that arise from time to time in the ordinary course of our business.  While we are unable to estimate a range of potential losses, we do not believe that any of the legal proceedings pending against us as of the date of this report will have a material adverse effect on our liquidity or financial condition.  As these matters are subject to inherent uncertainties, our view of these matters may change in the future.
	18
	Contractual Commitments
	We entered into a 25-year strategic relationship agreement with Gallup in January 2008 and a global joint venture agreement with Gallup in October 2012 that requires us to make payments over a 5-year period beginning January 2013.  We have minimum remaining contractual cash obligations of $43.9 million related to these agreements.
	In May 2011, we entered into a ten-year applications and technology services outsourcing agreement with HP Enterprise Services, LLC that contains minimum fee requirements.  Total payments over the remaining term, including an estimate for future contractual cost of living adjustments, must equal or exceed a minimum level of approximately $148.3 million; however, based on initial required service and equipment level assumptions, we estimate that the remaining payments will be approximately $309.2 million.  The agreement allows us to terminate all or a portion of the services after the first two years provided we pay certain termination fees, which could be material to the Company.

	On October 1, 2013, we entered into an Investment Agreement (the "Investment Agreement") with CareFirst Holdings, LLC ("CareFirst"), which is in addition to certain existing commercial agreements between us and CareFirst relating to, among other things, disease management and care coordination services (the "Commercial Agreements"). Pursuant to the Investment Agreement, we issued to CareFirst a convertible subordinated promissory note in the aggregate original principal amount of $20 million (the "CareFirst Convertible Note") for a purchase price of $20 million. The CareFirst Convertible Note bears interest at a rate of 4.75% per year, payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each calendar year, beginning on December 31, 2013.  If the CareFirst Convertible Note has not been fully converted or redeemed in accordance with its terms, it will mature on October 1, 2019.
	20
	The CareFirst Convertible Note is convertible into shares of our common stock at the conversion rate determined by dividing (a) the sum of the portion of the principal to be converted and accrued and unpaid interest with respect to such principal by (b) the conversion price equal to $22.41 per share of our common stock.  The conversion price is subject to adjustment for stock splits, stock dividends, recapitalizations, reorganizations, reclassifications and similar events.
	CareFirst has an opportunity to earn warrants to purchase shares of our common stock ("CareFirst Warrants") based on achievement of certain quarterly thresholds (the "Revenue Thresholds") for revenue derived from both the Commercial Agreements and from new business to us from third parties as a result of an introduction or referral to us by CareFirst (collectively, the "Quarterly Revenue").  If the Quarterly Revenue is greater than or equal to the applicable Revenue Threshold for any quarter ending on or prior to September 30, 2017, then we will issue to CareFirst a certain number of warrants exercisable for the number of shares of our common stock ("CareFirst Warrant Shares") determined in accordance with the terms of the Investment Agreement. The aggregate number of CareFirst Warrant Shares in any single 12-month period beginning on October 1, 2013 cannot exceed 400,000, and the aggregate number of CareFirst Warrant Shares issuable pursuant to the Investment Agreement cannot exceed 1,600,000.
	Also on October 1, 2013, in connection with the execution of the Investment Agreement, we entered into a Registration Rights Agreement with CareFirst (the "Registration Rights Agreement"), pursuant to which we agreed to use commercially reasonable efforts to cause any registration statement covering an underwritten offering of our common stock for our own account or for the account of any holder of our common stock (other than a registration statement on Form S-4 or Form S-8 or any successor thereto) to include those registrable common shares that any holder of such registrable common shares has requested to be registered.
	The term of the Investment Agreement expires on the earlier of (a) December 31, 2017 and (b) the first date on which no Commercial Agreement is in effect.

Interest rate description	'Borrowings under the Fifth Amended Credit Agreement generally bear interest at variable rates based on a margin or spread in excess of either (1) the one-month, two-month, three-month or six-month rate (or with the approval of affected lenders, nine-month or twelve-month rate) for Eurodollar deposits ("LIBOR") or (2) the greatest of (a) the SunTrust Bank prime lending rate, (b) the federal funds rate plus 0.50%, and (c) one-month LIBOR plus 1.00% (the "Base Rate"), as selected by the Company. The LIBOR margin varies between 1.75% and 3.00%, and the Base Rate margin varies between 0.75% and 2.00%, depending on our leverage ratio. On February 5, 2013, we entered into a First Amendment to the Fifth Amended Credit Agreement, which included, among other things, a temporary increase in the LIBOR and Base Rate margins of 0.25%. The increased margins are effective through December 31, 2013 and apply only in the event that our total funded debt to EBITDA ratio is greater than or equal to 3.50 to 1.00.
