Basis of Presentation	'
	Basis of Presentation
	Basis of presentation:
	The unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), pursuant to the Securities and Exchange Commission’s (“SEC”) rules and regulations for reporting on Form 10-Q, and following accounting policies consistent with the Company’s audited annual consolidated financial statements for the year ended December 31, 2013. The unaudited consolidated financial statements of the Company include its wholly-owned subsidiaries and all significant intercompany transactions and balances have been eliminated in consolidation. Amounts in the unaudited consolidated financial statements and notes thereto are expressed in U.S. dollars, except where indicated. The financial information included herein reflects all adjustments (consisting only of normal recurring adjustments), which, in the opinion of management, are necessary for a fair presentation of the results for the periods presented. Certain reclassifications have been made to conform the prior year's consolidated financial statements to the current year's presentation. The results of operations for the three and six months ended June 30, 2014 are not necessarily indicative of the results to be expected for the full year ending December 31, 2014. As of the issuance date of the Company’s financial statements, the Company has assessed whether subsequent events have occurred that require adjustment to or disclosure in these unaudited consolidated financial statements in accordance with Financial Accounting Standards Board’s (“FASB”) guidance.
	Pursuant to the SEC rules and regulations for reporting on Form 10-Q, certain information and note disclosures normally included in the annual consolidated financial statements prepared in accordance with GAAP have been condensed or excluded. As a result, these unaudited consolidated financial statements do not contain all the disclosures required to be included in the annual consolidated financial statements and should be read in conjunction with the most recent audited annual consolidated financial statements and notes thereto described in our Annual Report on Form 10-K for the year ended December 31, 2013.
	Use of estimates:
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Significant items subject to such estimates and assumptions include revenue recognition, rebates, purchase price allocation and contingent consideration in connection with acquisitions, valuation of property and equipment, valuation of intangible assets acquired and related amortization periods, impairment of goodwill, income tax uncertainties, contingencies and valuation allowances for receivables and income taxes. Actual results could differ from those estimates.

	Recent Accounting Pronouncements
	a) Recent accounting standards implemented
	In July 2013, the FASB issued authoritative guidance containing changes to the presentation of an unrecognized tax benefit when a loss or credit carryforward exists. The new standard requires the netting of unrecognized tax benefits against a deferred tax asset for a loss or other carryforward that would apply in the settlement of the uncertain tax positions. The Company adopted this standard on January 1, 2014; however, the implementation of the standard did not have a significant impact on its financial results or in the presentation and disclosure of its financial statements.
	No other new accounting standards have been adopted during the three and six months ended June 30, 2014.
	b) Recent accounting standards issued
	In June 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-12, Accounting for Share-Based Payments when the terms of an award provide that a performance target could be achieved after the requisite service period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target shall not be reflected in estimating the fair value of the award at the grant date. The amendments in this update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015 for all entities, however earlier adoption is permitted. Adoption of the standard is not expected to have a significant impact on the Company's financial results or in the presentation and disclosure of its financial statements.
	On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
	On April 10, 2014, the FASB issued (ASU) No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. The guidance applies prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The standard is required to be adopted by the Company in annual periods beginning on or after December 15, 2014, and interim periods within those annual periods. However, all entities may early adopt the guidance for new disposals (or new classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. Adoption of the standard is not expected to have a significant impact on the Company's financial results or in the presentation and disclosure of its financial statements.
	No other new standards have been issued during the three and six months ended June 30, 2014 that the Company assessed to have a significant impact on its financial results or in the presentation and disclosure of its financial statements.

	Restat Acquisition
	On October 1, 2013, the Company completed the acquisition of all of the outstanding equity interests of Restat, LLC ("Restat"), a privately-held PBM based in Milwaukee, Wisconsin, for a purchase price of $409.5 million in cash subject to certain customary post-closing adjustments. The purchase price was funded from Catamaran’s existing cash balance and $350.0 million in borrowings under a five-year senior secured revolving credit facility (the “Revolving Facility”). The acquisition provides the Company the opportunity to bring Catamaran's full-suite of technology and clinical services to Restat's clients, including mail and specialty pharmacy services. The results of Restat have been included in the Company's results since October 1, 2013.
	The acquisition was accounted for under the acquisition method of accounting with the Company treated as the acquiring entity. Accordingly, the consideration paid by the Company to complete the acquisition has been recorded to the assets acquired and liabilities assumed based upon their estimated fair values as of the date of acquisition. The carrying values for current assets and liabilities were deemed to approximate their fair values due to the short-term nature of their maturities. Fair values for acquired amortizable intangible assets were determined as follows: customer relationships were valued using an excess earnings model based on expected future revenues derived from the customers acquired, non-compete agreements were valued using discounted cash flow models based on expected future results of Restat and trademarks/tradenames were valued using a royalty savings model based on future projected revenues of Restat. The excess of the purchase price over the estimated fair values of the net assets acquired was recorded as goodwill.
	All of the assets and liabilities recorded for the acquisition are included within the Company's PBM segment. The residual amount of the purchase price after allocation to identifiable net assets represents goodwill. Goodwill is non-amortizing for financial statement purposes. Goodwill of $227.8 million related to the Restat acquisition is tax deductible. The goodwill recognized by the Company represents many of the synergies and business growth opportunities that the Company anticipates may be realized from the acquisition of Restat. The synergies include improved pricing from the Company's suppliers due to the increased volume of prescription drug purchases, pull through opportunities of the Company's mail and specialty service offerings, and a more efficient leveraging of resources to achieve operating profits.
	The following summarizes the fair values assigned to the assets acquired and liabilities assumed at the acquisition date (in thousands):
		Initial Amounts Recognized at Acquisition Date (a)			Measurement Period Adjustments (b)			Current Measurement Period Adjustments (c)		Current Amounts Recognized at Acquisition Date
	Accounts receivable	$	13,842		$	—		$	—	$	13,842

	Net assets acquired	$	382,610		$	2,026		$	—	$	384,636
	(a) As previously reported in the Company's Form 10-K for the period ended December 31, 2013.
	(b) These measurement period adjustments were recorded during Q1 2014 to reflect an additional $2.0 million paid to former Restat owners for working capital reconciliation as well as changes in the estimated fair values of the associated assets acquired and liabilities assumed.
	(c) These represent measurement period adjustments during the three months ended June 30, 2014 and were recorded to reflect changes in the estimated fair values of the associated Restat assets acquired and liabilities assumed based on factors existing as of the acquisition date.
	During the three and six months ended June 30, 2014, the Company recognized $8.7 million and $17.4 million, respectively, of amortization expense from intangible assets acquired in the Restat acquisition. Amortization associated with the Restat acquisition for the remainder of 2014 is expected to be $16.4 million.
	The estimated fair values and useful lives of intangible assets acquired are as follows (dollars in thousands):
		Fair Value			Useful Life
	Customer relationships - PBM	$	143,200		10 years
	Customer relationships - cash card	35,500			3 years
	Trademarks/Trade names	1,000			1 year
	Non-compete agreements	3,020			5 years
	Total	$	182,720
	None of the acquired intangible assets will have any residual value at the end of the amortization periods. There were no in-process research and development assets acquired.
	Unaudited Pro Forma Financial Information
	The following unaudited pro forma financial information presents the combined historical results of operations of the Company and its acquisition of Restat as if the acquisition had occurred on the first day of the fiscal year prior to the fiscal year when the acquisition was completed. The unaudited pro forma financial information includes certain adjustments related to the acquisition, such as increased amortization from the fair value of intangible assets acquired recorded as part of the purchase accounting, the elimination of transactions between the Company and the acquired entities, and related income tax effects.
	Unaudited pro forma results of operations are as follows (in thousands, except share and per share amounts):

	4.75% Senior Notes
	In March 2014, the Company issued $500.0 million aggregate principal amount of 4.75% Senior Notes due 2021 (the “Senior Notes”). The Senior Notes mature on March 15, 2021 and bear interest at 4.75% per year. The Company will pay interest on the Senior Notes on March 15 and September 15 of each year, or the first business day thereafter if such date is not a business day, commencing on September 15, 2014. The Company received approximately $492.5 million in net proceeds from the Senior Note offering, after deducting $7.5 million in underwriting discounts. Additionally the Company incurred approximately $2.0 million in offering expenses. The Company used part of the net proceeds from this offering to repay $300.0 million of the Company's outstanding borrowings under the secured revolving credit facility (the "Revolving Facility"). The Company plans to use the remainder of the net proceeds from this offering for general corporate purposes.
	As discussed, in connection with the Senior Notes, the Company incurred approximately $7.5 million in underwriting debt discount and approximately $2.0 million in debt issuance costs. The $7.5 million debt discount incurred in connection with the Senior Notes is presented on the consolidated balance sheet as a reduction to long-term debt. The debt discount amounts are being amortized to interest expense over the life of the Senior Notes. The Company uses the straight-line method to amortize the debt discount amounts as it does not result in a materially different amount of interest expense than the effective interest rate method. The $2.0 million in offering expenses incurred in connection with the issuance of the Senior Notes are presented on the consolidated balance sheet as other assets. The offering expenses are being amortized to interest expense over the life of the Senior Notes using the straight-line method. The amortization related to financing costs and debt discounts totaled $0.3 million and $0.4 million for the three and six months ended June 30, 2014, respectively.
	Guarantees
	The Senior Notes are jointly and severally and fully and unconditionally guaranteed by each of the Company’s existing and future wholly-owned subsidiaries that guarantees obligations under (i) the credit agreement or (ii) certain other future indebtedness with an aggregate principal amount in excess of $175.0 million.
	A subsidiary guarantor will be released from its obligations under its respective guarantee of the Senior Notes upon the release or discharge of such subsidiary guarantor from its guarantee of obligations under the credit agreement or certain other future indebtedness in an aggregate principal amount in excess of $175.0 million, or upon the earlier occurrence of certain other customary circumstances as set forth in the indenture. The Senior Notes and the guarantees by the subsidiary guarantors are the general senior unsecured obligations of the Company and the subsidiary guarantors. They rank equally in right of payment with the existing and future senior unsecured indebtedness of the Company and the subsidiary guarantors.
	Prepayments and Repayments
	Prior to the scheduled maturity of the Senior Notes, the Company may at any time redeem all or a part of the Senior Notes, upon not less than 30 nor more than 60 days’ prior written notice at a redemption price equal to the greater of: (i) 100% of the principal amount of the Senior Notes to be redeemed, and (ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the Senior Notes to be redeemed (exclusive of interest accrued to the applicable redemption date) discounted to such redemption date on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at the then current treasury rate plus 50 basis points, plus, in each case, accrued and unpaid interest thereon to, but not including, the applicable redemption date.
	If the Company experiences a change of control triggering event (as defined in the supplemental indenture), holders of the Senior Notes may require the Company to purchase the Senior Notes at a purchase price equal to 101% of the aggregate principal amount, plus accrued and unpaid interest, if any, to the date of purchase.
	The Company is not required to make mandatory redemption payments or sinking fund payments with respect to the Senior Notes.
	Certain Covenants and Events of Default
	The indenture governing the Senior Notes includes certain restrictive covenants, including covenants that limit the Company's ability and the ability of our subsidiaries to, among other things, incur secured debt; enter into sale and leaseback transactions; and amalgamate, consolidate, merge or transfer substantially all of the Company's assets to another entity. The covenants are subject to a number of important exceptions and qualifications set forth in the indenture.
	The indenture governing the Senior Notes provides for customary events of default (subject in certain cases to customary grace and cure periods), which include nonpayment, breach of covenants in the indenture and certain events of bankruptcy and insolvency. Generally, if an event of default occurs, the trustee or holders of at least 25% in aggregate principal amount of and accrued but unpaid interest on the then outstanding Senior Notes may declare the principal amount of all the Senior Notes to be due and payable immediately. As of June 30, 2014, the Company was in compliance with the covenants under the Senior Notes.
	Senior Secured Credit Facility
	Concurrent with the consummation of the Catalyst Health Solutions Inc. merger ("Catalyst Merger"), on July 2, 2012, the Company entered into a credit agreement (as amended and supplemented from time to time, the “Credit Agreement”) with JPMorgan Chase Bank, N.A. (“JPMCB”), as administrative agent, and a syndicate of lenders in an aggregate principal amount of $1.8 billion. The Credit Agreement provides for (i) a five-year senior secured term loan facility in the amount of $1.0 billion (the “Term Loan Facility”) and (ii) a five-year Revolving Facility in the amount of $800.0 million.
	The Company made a principal repayment of $6.3 million in April 2014 on the Term Loan facility leaving the Company with $975.0 million outstanding as of June 30, 2014. In March 2014 the Company used the proceeds from the offering of the Senior Notes (refer above for a detailed discussion) to repay $300.0 million of the outstanding borrowings under the Revolving Facility. As of June 30, 2014 the Company had approximately $800.0 million of available borrowing capacity under the Revolving Facility. The amortization related to financing costs and debt discounts associated with the Credit Agreement totaled $2.1 million and $2.4 million for the three months ended June 30, 2014 and June 30, 2013, respectively. The amortization related to financing costs and debt discounts associated with the Credit Agreement totaled $4.3 million and $4.9 million for the six months ended June 30, 2014 and June 30, 2013, respectively.
	Interest and Fees
	The interest rates applicable to the Term Loan Facility and the Revolving Facility are based on a fluctuating rate of interest measured by reference to either, at the Company’s option, (a) an adjusted London Interbank Offered Rate (adjusted for maximum reserves) (“LIBOR”), plus an applicable margin or (b) an alternative base rate (which is the greatest of (i) the prime rate, (ii) the Federal Funds rate plus 0.5% and (iii) one-month LIBOR plus 1.0%), plus an applicable margin. The applicable margin, in each case, is adjusted from time to time based on the Company’s consolidated leverage ratio as of the last day of each fiscal quarter. The applicable margin for all borrowings is 0.875% per annum with respect to base rate borrowings and 1.875% per annum with respect to LIBOR borrowings. The Company intends to continue to elect the LIBOR rate as it has previously done during the term of the Credit Agreement. This resulted in an applicable interest rate of 2.06% at June 30, 2014 for both the Term Loan Facility and the Revolving Facility. See Note 11 — Financial Instruments for information on the Company's interest rate swap agreements. In addition to paying interest on outstanding principal under the Credit Agreement, the Company is required to pay a commitment fee to the lenders in respect of the unutilized commitments under the Credit Agreement at a fluctuating rate based on the Company’s leverage ratio.
	Certain Covenants and Events of Default
	The Credit Agreement contains a number of covenants that require the Company to maintain certain financial ratios, meet customary reporting requirements and restrict, with certain exceptions, transactions the Company or its subsidiaries may enter into, in each case as described further in the Company's 2013 Annual Report on Form 10-K. As of June 30, 2014, the Company was in compliance with the covenants of the Credit Agreement.
	Maturity
	Principal amounts outstanding under the Revolving Facility are due and payable in full on June 1, 2018. Principal repayments on the Term Loan Facility will be due as follows (in thousands):
	Year	Amount due
	2014	$	37,500
	2015	68,750
	2016	93,750
	2017	118,750
	2018	656,250
	Total	$	975,000
	Guarantees and Collateral
	The Company’s obligations under the Credit Agreement are guaranteed by all existing and future, direct and indirect, material subsidiaries of the Company (collectively, the “Subsidiary Guarantors”).  In addition, the Company and each Subsidiary Guarantor have pledged substantially all of their assets, subject to certain exceptions, to secure the Company’s obligations under the Credit Agreement.
	The carrying value of the Company's debt at June 30, 2014 approximates its fair value.

	In July 2014, the Company received a subpoena from the United States Attorney's Office for the District of Rhode Island, requesting documents and information concerning bona fide service fees and rebates received from certain pharmaceutical manufacturers in connection with certain drugs utilized under Part D of the Medicare program. The Company has been cooperating with the government and collecting documents in response to the subpoena.
	From time to time in connection with its operations, the Company is named as a defendant in actions for damages and costs allegedly sustained by third party plaintiffs. The Company has considered these proceedings and disputes in determining the necessity of any accruals for losses that are probable and reasonably estimable. In addition, various aspects of the Company’s business may subject it to litigation and liability for damages arising from errors in processing the pricing of prescription drug claims, failure to meet performance measures within certain contracts relating to its services performed, its ability to obtain certain levels of discounts or rebates on prescription purchases from retail pharmacies and drug manufacturers or other actions or omissions. The Company’s recorded accruals are based on estimates developed with consideration given to the potential merits of claims or quantification of any performance obligations. The Company takes into account its history of claims, the limitations of any insurance coverage, advice from outside counsel, and management’s strategy with regard to the settlement or defense of such claims and obligations. While the ultimate outcome of those claims, lawsuits or performance obligations cannot be predicted with certainty, the Company believes, based on its understanding of the facts of these claims and performance obligations, that adequate provisions have been recorded in the accounts where required.

Financial Instruments	'
	Financial Instruments
	The Company is subject to interest rate risk related to the variable rate debt under the Credit Agreement. When interest rates increase, interest expense would also increase. Conversely, when interest rates decrease, interest expense would also decrease.
	In order to manage fluctuations in cash flows resulting from interest rate risk attributable to changes in the benchmark interest rates used in the Credit Agreement, the Company entered into a 3-year interest rate swap agreement with a total notional amount of $500 million. The swap agreement fixed the variable LIBOR rate on the Company's Term Loan Facility to 0.52%, resulting in a current effective rate as of June 30, 2014 of 2.39% after taking into account the 1.88% margin per the Credit Agreement, as amended. Under the interest rate swap, the Company receives LIBOR-based variable interest rate payments and makes fixed interest rate payments, thereby creating the equivalent to fixed-rate debt with respect to the notional amount of such swap agreements. This interest rate contract derivative instrument was designated as a cash flow hedge upon inception in August, 2012 and it expires in August 2015.
	The Company assesses interest rate cash flow risk by continually identifying and monitoring changes in interest rate exposures that may adversely impact expected future cash flows and by evaluating hedging opportunities. The Company does not enter into derivative instruments for any purpose other than hedging identified exposures. That is, the Company does not speculate using derivative instruments and has not designated any instruments as fair value hedges or hedges of the foreign currency exposure of a net investment in foreign operations.
	The fair value of the interest rate swap liability as of June 30, 2014 was $1.8 million. Interest expense for the three and six months ended June 30, 2014 includes $0.4 million and $0.8 million of expense reclassified from other comprehensive income into current earnings. Interest expense for the three and six months ended June 30, 2013 includes $0.3 million and $0.7 million of expense reclassified from other comprehensive income into current earnings. As of June 30, 2014, approximately $1.7 million of deferred expenses related to the derivative instruments accumulated in other comprehensive income is expected to be reclassified as interest expense during the next twelve months. This expectation is based on the expected timing of the occurrence of the hedged forecasted transactions and assumes the current LIBOR rate will remain consistent. Fluctuations in the market LIBOR rate will have an impact on the amount of expense reclassified from accumulated other comprehensive income to interest expense, as well as the overall fair value of the derivative instrument.

Fair Value	'
	Fair Value
	Fair value measurement guidance defines a three-level hierarchy to prioritize the inputs to valuation techniques used to measure fair value into three broad levels, with Level 1 considered the most reliable. During the three and six months ended June 30, 2014, there were no movements of fair value measurements between Levels 1, 2 and 3. For assets and liabilities measured at fair value on a recurring basis in the consolidated balance sheets, the table below categorizes fair value measurements across the three levels as of June 30, 2014 and December 31, 2013 (in thousands):
		June 30, 2014
		Quoted Prices in Active Markets (Level 1)		Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
	Liabilities:
	Contingent purchase price consideration	$	—	$	—	$	20,000	$	20,000

	Contingent purchase price consideration	$	—	$	—	$	19,954	$	19,954
	Derivative	$	—	$	1,719	$	—	$	1,719
	When available and appropriate, the Company uses quoted market prices in active markets to determine fair value, and classifies such items within Level 1. Level 1 values only include instruments traded on a public exchange. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability or can be derived principally from or corroborated by observable market data. If the Company were to use one or more significant unobservable inputs for a model-derived valuation, the resulting valuation would be classified in Level 3.
	Contingent purchase price consideration
	The contingent purchase price consideration liability reflects the fair values of potential future payments related to certain legacy acquisitions. The potential future payments are contingent upon the acquired entities meeting certain revenue, gross margin and client retention milestones. As of June 30, 2014, the fair value of the contingent purchase price consideration was $20.0 million and was recorded as accrued expenses and other current liabilities in the consolidated balance sheet.
	As the fair value measurement for the contingent consideration is based on inputs not observed in the market, this measurement is classified as Level 3 measurements as defined by fair value measurements guidance.
	Derivatives
	Derivative liabilities relate to the interest rate swap agreement (refer to Note 11 — Financial Instruments for further information), which had a fair value of $1.8 million as of June 30, 2014. As the fair value measurement for the derivative instrument is based on quoted prices from a financial institution, this measurement is classified as Level 2 measurement as defined by fair value measurements guidance.

The financial information included herein reflects all adjustments (consisting only of normal recurring adjustments), which, in the opinion of management, are necessary for a fair presentation of the results for the periods presented. Certain reclassifications have been made to conform the prior year's consolidated financial statements to the current year's presentation. The results of operations for the three and six months ended June 30, 2014 are not necessarily indicative of the results to be expected for the full year ending December 31, 2014. As of the issuance date of the Company’s financial statements, the Company has assessed whether subsequent events have occurred that require adjustment to or disclosure in these unaudited consolidated financial statements in accordance with Financial Accounting Standards Board’s (“FASB”) guidance.
	Pursuant to the SEC rules and regulations for reporting on Form 10-Q, certain information and note disclosures normally included in the annual consolidated financial statements prepared in accordance with GAAP have been condensed or excluded. As a result, these unaudited consolidated financial statements do not contain all the disclosures required to be included in the annual consolidated financial statements and should be read in conjunction with the most recent audited annual consolidated financial statements and notes thereto described in our Annual Report on Form 10-K for the year ended December 31, 2013.
Use of estimates	'
	Use of estimates:
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Significant items subject to such estimates and assumptions include revenue recognition, rebates, purchase price allocation and contingent consideration in connection with acquisitions, valuation of property and equipment, valuation of intangible assets acquired and related amortization periods, impairment of goodwill, income tax uncertainties, contingencies and valuation allowances for receivables and income taxes. Actual results could differ from those estimates.
