Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Omnicare continuously evaluates contingencies based upon the best available information. The Company believes that liabilities have been recorded to the extent necessary in cases where the outcome is considered probable and reasonably estimable. To the extent that resolution of contingencies results in amounts that vary from the Company’s recorded liabilities, future earnings will be charged or credited accordingly. On October 5, 2011, a qui tam complaint, entitled United States ex rel. Donald Gale v. Omnicare, Inc., No. 1:10-cv-0127, was served on the Company. The case had been filed on January 19, 2010 under seal with the U.S. District Court for the Northern District of Ohio, Eastern Division. The complaint was unsealed by the Court on June 9, 2011 after the U.S. Department of Justice notified the court that it has declined to intervene in this action. The complaint was brought by Donald Gale as a private party qui tam relator on behalf of the federal government. The action alleges civil violations of the False Claims Act based on allegations that the Company provided certain customer facilities with discounts and other forms of remuneration in return for referrals of business in violation of the Anti-Kickback Statute, and offered pricing terms in violation of the "most favored customer" pricing laws of various state Medicaid plans. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action if pursued. On August 4, 2011, a qui tam complaint, entitled United States of America ex rel. Fox Rx, Inc. v. Omnicare, Inc. and Neighborcare, Inc., No. 1:11-cv-0962, that was filed under seal with the U.S. District Court for the Northern District of Georgia, was unsealed by the Court. The U.S. Department of Justice has declined to intervene in this action. The Company has not been served with the complaint in this action. The complaint was brought by Fox Rx, Inc. as a qui tam relator on behalf of the federal government. The action alleges civil violations of the False Claims Act based on allegations that the Company billed Medicare Part D for medically unnecessary antipsychotic drugs, increased the dispensing fees by artificially shortening the supply of prescribed medication, submitted claims for antipsychotic drugs without complying with Fox Rx, Inc.’s prior approval requirements, and waived or failed to collect copayments from patients to induce the use of prescription drugs. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action if pursued. On August 24, 2011, a class action complaint entitled Ansfield v. Omnicare, Inc., et al. was filed on behalf of a putative class of all purchasers of the Company's common stock from January 10, 2007 through August 5, 2010 against the Company and certain of its current and former officers in the United States District Court for the Eastern District of Kentucky, alleging violations of federal securities law in connection with alleged false and misleading statements with respect to the Company's compliance with federal and state Medicare and Medicaid laws and regulations. On October 21, 2011, a class action complaint entitled Jacksonville Police & Fire Pension Fund v. Omnicare, Inc. et al. was filed on behalf of the same putative class of purchasers as is referenced in the Ansfield complaint, against the Company and certain of its current and former officers, in the U.S. District Court for the Eastern District of Kentucky. Plaintiffs allege substantially the same violations of federal securities law as are alleged in the Ansfield complaint. Both complaints seek unspecified money damages. Motions for the appointment of lead plaintiff and lead counsel in these cases have been filed, fully briefed and argued and are awaiting decision, following which a consolidated amended complaint is expected to be filed. The Company believes that the claims asserted are without merit and intends to defend against them vigorously. On December 13, 2010, a qui tam complaint entitled United States ex rel. Bartz v. Ortho-McNeil Pharmaceuticals, Inc., Johnson & Johnson, Janssen Pharmaceutica, Inc., Janssen Pharmaceutica Products, LP, McKesson Corporation, McKesson Specialty Pharmaceutical, LLC and Omnicare, Inc., Civil Action No. 05-cv-6010, which had been filed under seal with the U.S. District Court in Philadelphia, Pennsylvania, was ordered unsealed by the court. The complaint was brought by Scott Bartz, a former employee of Johnson & Johnson, as a private party qui tam relator on behalf of the federal government and several state and local governments. The U.S. Department of Justice has notified the court that it has declined to intervene. The action alleges civil violations of the False Claims Act based on allegations that Johnson & Johnson and its affiliates provided the Company and McKesson with rebates, free drugs and other remuneration in order to limit Johnson & Johnson’s rebate liability to Medicaid. The court granted Johnson & Johnson’s motion to transfer the action to U.S. District Court in Boston, Massachusets in February 2011. The Company filed a motion to dismiss the complaint on May 27, 2011. On June 10, 2011, the relator filed a notice of intent to voluntarily dismiss its claims against the Company, which is pending. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action if pursued. On September 15, 2010, Omnicare entered into settlement agreements, without any finding of wrongdoing or admission of liability, with the State of Michigan, the Commonwealth of Massachusetts and David M. Kammerer ("Relator"), relating to sealed qui tam litigation originally filed by Relator in Ohio federal court in August 2003. The Company has paid $11.6 million pursuant to the Michigan settlement agreement and $9.45 million pursuant to the Massachusetts settlement agreement to resolve allegations of inappropriate billing, beginning in August 1997, under the states' usual and customary charge provisions. The Company has paid Relator's expenses and attorneys' fees of $385,000. The Company recorded provisions of $24.2 million for these payments, and a separate unrelated matter with another state which is still under review, in the quarter ended June 30, 2010. On October 29, 2010, a qui tam complaint entitled United States ex rel. Banigan and Templin, et al. v. Organon USA, Inc., Omnicare, Inc. and Pharmerica, Inc., Civil No. 07-12153-RWZ, that had been filed under seal with the U.S. District Court in Boston, Massachusetts, was ordered unsealed by the court. The complaint was brought by James Banigan and Richard Templin, former employees of Organon, as private party qui tam relators on behalf of the federal government and several state and local governments. The action alleges civil violations of the False Claims Act based on allegations that Organon USA, Inc. and its affiliates paid the Company and several other long-term care pharmacies rebates, post-purchase discounts and other forms of remuneration in return for purchasing pharmaceuticals from Organon and taking steps to increase the purchase of Organon's drugs in violation of the Anti-Kickback Statute. The U.S. Department of Justice has notified the court that it has declined to intervene in this action. The Company filed a motion to dismiss the complaint on July 7, 2011. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action if pursued. The Drug Enforcement Administration ("DEA") is investigating alleged errors and deficiencies in paperwork requirements for controlled substance dispensing at several of the Company's pharmacies in Ohio. The United States Attorney's Office, Northern District of Ohio ("AUSA"), is conducting an investigation relating to this matter, and may seek monetary penalties. The AUSA is also conducting a criminal investigation of several current and former employees in connection with the DEA audits. The Company is cooperating with these investigations and intends to vigorously defend itself if these matters are pursued. The Company recorded a provision for this matter in the quarters ended December 31 and June 30, 2011 and December 31, 2010. The Company is no longer the subject of a criminal investigation by the AUSA in connection with the DEA audits. On April 14, 2010, a purported shareholder derivative action, entitled Manville Personal Injury Settlement Trust v. Gemunder, et al., Case No. 10-CI-01212, was filed in Kentucky State Court, against members of the Board and certain current and former officers of the Company, individually, purporting to assert claims for breach of fiduciary duty, unjust enrichment, gross mismanagement, and waste of corporate assets arising out of alleged violations of federal and state laws prohibiting the payment of illegal kickbacks and the submission of false claims in connection with the Medicare and Medicaid healthcare programs. Plaintiff alleges that the Board and senior management caused the company to violate these laws, which has resulted in over $100 million in fines and penalties paid by Omnicare and exposed the Company and certain individual defendants to potential civil and criminal liability. On April 27, 2011 the court entered an order denying defendants’ motion to dismiss the complaint for failure to make a pre-suit demand and failure to state a claim. Defendants filed a notice of appeal from the decision in the Kentucky Court of Appeals, and plaintiff moved to dismiss that appeal on the grounds that the order denying defendants’ motion to dismiss is not subject to an immediate appeal under Kentucky law. On October 6, 2011, the Kentucky Court of Appeals granted plaintiff’s motion on the grounds that the appeal was premature. The case is now in the discovery stage. The individual defendants have denied all allegations of wrongdoing, believe the claims against them to be completely without merit and intend to vigorously defend themselves in this action. On April 2, 2010, a purported class action lawsuit, entitled Spindler, et al. v. Johnson & Johnson Corp., Omnicare, Inc. and Does 1-10, Case No. CV-10-1414, was filed in the United States District Court for the Northern District of California, San Francisco Division, against Johnson & Johnson (“J&J”), the Company and certain unnamed defendants asserting violations of federal antitrust law and California unfair competition law arising out of certain arrangements between J&J and the Company. Plaintiffs allege, among other things, that the Company violated these laws by entering into agreements with J&J to promote J&J products. On January 21, 2011, the court dismissed the amended complaint and granted permission to file a new amended complaint, which was filed in February 2011. On August 1, 2011, the court dismissed the second amended complaint and, on October 25, 2011, after plaintiffs had declined the court's invitation to further amend the complaint, the district court dismissed the matter with prejudice. Plaintiffs have filed a notice of appeal with the Ninth Circuit Court of Appeals. Briefing of the appeal is scheduled to be completed by April 9, 2012. The Company believes the claims to be entirely without merit and intends to vigorously defend the dismissal of those claims on appeal. On January 8, 2010, a qui tam complaint, entitled United States ex rel. Resnick and Nehls v. Omnicare, Inc., Morris Esformes, Phillip Esformes and Lancaster Ltd. d/b/a Lancaster Health Group, No. 1:07cv5777, that was filed under seal with the U.S. District Court in Chicago, Illinois was unsealed by the court. The U.S. Department of Justice and the State of Illinois have notified the court that they have declined to intervene in this action. The complaint was brought by Adam Resnick and Maureen Nehls as private party “qui tam relators” on behalf of the federal government and two state governments. The action alleges civil violations of the False Claims Act and certain state statutes based on allegations that Omnicare acquired certain institutional pharmacies at above-market rates in violation of the Anti-Kickback Statute and applicable state statutes. On December 1, 2010, Resnick filed a motion to withdraw as a relator, which the court granted on December 14, 2010. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action. On or about March 12, 2010, a qui tam complaint entitled State of Illinois, ex rel. Adam B. Resnick and Maureen Nehls v. Omnicare, Inc. Morris Esformes, Phillip Esformes, and Tim Dacy, No. D6 L 1926 that was filed under seal in Illinois state court, was unsealed by the court. The State of Illinois notified the court that it declined to intervene in the action. This complaint was brought by the same two qui tam relators, Adam Resnick and Maureen Nehls, that brought the complaint in the United States District Court in Chicago described above. This complaint is based on allegations nearly identical to a portion of the allegations contained in that federal action. The Company has not been served with the complaint in this action. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action if pursued. On June 11, 2010, a qui tam complaint, entitled United States ex rel. Stone v. Omnicare Inc., No. 1:09cv4319, that was filed under seal with the U.S. District Court in Chicago, Illinois was unsealed by the court. The U.S. Department of Justice and the various states named in the complaint have notified the court that they have declined to intervene in this action. The complaint was brought by John Stone, the Company’s former Vice President of Internal Audit, as a private party qui tam relator on behalf of the federal government and several state governments. The action alleges civil violations of the False Claims Act and certain state statutes based on allegations that the Company submitted claims for reimbursement for certain ancillary services that did not conform with Medicare and Medicaid regulations, submitted claims for reimbursement from newly acquired pharmacies that were in violation of certain Medicaid and Medicare regulations, violated certain FDA regulations regarding the storage and handling of a particular drug, and violated certain Medicaid billing regulations relating to usual and customary charges. Relator also asserts against the Company a retaliatory discharge claim under the False Claims Act. On November 1, 2010, the Company filed a motion to dismiss the lawsuit. Relator responded and conceded to dismissal of one of the counts. On July 7, 2011, the court granted the Company's motion in part and denied it in part. The court granted the motion as to the allegations that the Company submitted claims for reimbursement for certain ancillary services that did not conform with Medicare and Medicaid regulations and submitted claims for reimbursement from newly acquired pharmacies that were in violation of certain Medicaid and Medicare regulations; the court dismissed those counts without prejudice. The court denied the Company's motion as to the allegations that the Company violated certain FDA regulations regarding the storage and handling of a particular drug and retaliated against Relator. On September 15, 2011, Relator filed an Amended Complaint. He repeated his claim that the Company submitted false claims for certain ancillary services that did not conform with Medicare and Medicaid regulations. Relator also asserted a claim in the Amended Complaint that the Company submitted false claims to the Nevada Medicaid program for a particular drug. Relator repeated his retaliatory discharge claim. The Company filed a motion to dismiss the Amended Complaint on November 15, 2011. The Relator has filed a response in opposition to that motion. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action. On November 19, 2010, the Company was served with a second amended qui tam complaint entitled United States ex rel. Rostholder v. Omnicare, Inc. and Omnicare Distribution Center, LLC f/k/a Heartland Repack Services LLC, No. CCB-07-1283, that was filed under seal with the U.S. District Court in Baltimore, Maryland in July 2009. The U.S. Department of Justice notified the court on April 22, 2009 that it declined to intervene in this action. The complaint was brought by Barry Rostholder as a private party qui tam relator on behalf of the federal government and several state and local governments. The action, in general, alleges civil violations of the False Claims Act based on allegations that the Company submitted claims for reimbursement for drugs that were repackaged at its Heartland repackaging facility in violation of certain FDA regulations. These allegations arise from the previously disclosed issues experienced by the Company at its Heartland repackaging facility, which suspended operations in 2006. On September 30, 2011, the Company filed a motion to dismiss the lawsuit in its entirety, which has now been fully briefed. The Company believes that the claims in the complaint are without merit and intends to vigorously defend itself in this action if pursued. As part of the previously disclosed civil settlement agreement entered into by the Company with the U.S. Attorney’s Office, District of Massachusetts in November 2009, the Company also entered into an amended and restated corporate integrity agreement (“CIA”) with the Department of Health and Human Services Office of the Inspector General with a term of five years from November 2, 2009. Pursuant to the CIA, the Company is required, among other things, to (i) create procedures designed to ensure that each existing, new or renewed arrangement with any actual or potential source of health care business or referrals to Omnicare or any actual or potential recipient of health care business or referrals from Omnicare does not violate the Anti-Kickback Statute, 42 U.S.C. (§) 1320a-7b(b) or related regulations, directives and guidance, including creating and maintaining a database of such arrangements; (ii) retain an independent review organization to review the Company’s compliance with the terms of the CIA and report to OIG regarding that compliance; and (iii) provide training for certain Company employees as to the Company’s requirements under the CIA. The requirements of the Company’s prior corporate integrity agreement obligating the Company to create and maintain procedures designed to ensure that all therapeutic interchange programs are developed and implemented by Omnicare consistent with the CIA and federal and state laws for obtaining prior authorization from the prescriber before making a therapeutic interchange of a drug and to maintain procedures for the accurate preparation and submission of claims for federal health care program beneficiaries in hospice programs, have been incorporated into the amended and restated CIA without modification. The requirements of the CIA have resulted in increased costs to maintain the Company’s compliance program and greater scrutiny by federal regulatory authorities. Violations of the corporate integrity agreement could subject the Company to significant monetary penalties. Consistent with the CIA, the Company is reviewing its contracts to ensure compliance with applicable laws and regulations. As a result of this review, pricing under certain of its consultant pharmacist services contracts have been increased and will continue to be increased, and these price increases have resulted and may continue to result in the loss of certain contracts. In February 2006, two substantially similar putative class action lawsuits were filed in the United States District Court for the Eastern District of Kentucky, and were consolidated and entitled Indiana State Dist. Council of Laborers & HOD Carriers Pension & Welfare Fund v. Omnicare, Inc., et al., No. 2:06cv26. The amended consolidated complaint was filed against Omnicare, three of its officers and two of its directors and purported to be brought on behalf of all open-market purchasers of Omnicare common stock from August 3, 2005 through July 27, 2006, as well as all purchasers who bought their shares in the Company's public offering in December 2005. The complaint contained claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (and Rule 10b-5) and Section 11 of the Securities Act of 1933 and sought, among other things, compensatory damages and injunctive relief. Plaintiffs alleged that Omnicare (i) artificially inflated its earnings (and failed to file GAAP-compliant financial statements) by engaging in improper generic drug substitution, improper revenue recognition and overvaluation of receivables and inventories; (ii) failed to timely disclose its contractual dispute with UnitedHealth Group Inc.; (iii) failed to timely record certain special litigation reserves; and (iv) made other allegedly false and misleading statements about the Company’s business, prospects and compliance with applicable laws and regulations. The defendants filed a motion to dismiss the amended complaint on March 12, 2007, and on October 12, 2007, the court dismissed the case. On November 9, 2007, plaintiffs appealed the dismissal to the United States Court of Appeals for the Sixth Circuit. On October 21, 2009, the Sixth Circuit Court of Appeals generally affirmed the district court's dismissal, dismissing plaintiff's claims for violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5. However, the appellate court reversed the dismissal for the claim brought for violation of Section 11 of the Securities Act of 1933, and returned the case to the district court for further proceedings. On December 30, 2010, plaintiffs filed a motion in the district court requesting permission to file a third amended complaint. On February 4, 2011, the defendants filed a motion to dismiss the sole remaining claim in plaintiff's second amended complaint. On July 14, 2011, the court granted both motions and deemed the third amended complaint filed. This complaint asserts a claim under Section 11 of the Securities Act of 1933 on behalf of all purchasers of Omnicare common stock in the December 2005 public offering. The new complaint alleges that the 2005 registration statement contained false and misleading statements regarding Omnicare's policy of compliance with all applicable laws and regulations with particular emphasis on allegations of violation of the federal anti-kickback law in connection with three of Omnicare's acquisitions, Omnicare's contracts with two of its suppliers and its provision of pharmacist consultant services. On August 19, 2011, the defendants filed a motion to dismiss plaintiffs' most recent complaint and on February 13, 2012 the court dismissed the case and struck the case from the docket. On February 13, 2006, two substantially similar shareholder derivative actions, entitled Isak v. Gemunder, et al., Case No. 06-CI-390, and Fragnoli v. Hutton, et al., Case No. 06-CI-389, were filed in Kentucky State Circuit Court, Kenton Circuit, against the members of Omnicare’s board of directors, individually, purporting to assert claims for breach of fiduciary duty, abuse of control, gross mismanagement, waste of corporate assets and unjust enrichment arising out of the Company’s alleged violations of federal and state health care laws based upon the same purportedly improper generic drug substitution that is the subject of the federal purported class action lawsuits. The complaints seek, among other things, damages, restitution and injunctive relief. The Isak and Fragnoli actions were later consolidated by agreement of the parties. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action. The years ended 2011, 2010 and 2009 included a $55.7 million, $113.7 million and $77.4 million charge, respectively, reflected in “Settlement, litigation and other related charges” of the Consolidated Statements of Income, primarily for estimated litigation and other related settlements and associated professional expenses for resolution of certain regulatory matters with the federal government and various states, certain large customer disputes, the investigation by the federal government and certain states relating to drug substitutions; purported class and derivative actions against the Company and costs associated with the settlement of the investigation by the United States Attorney’s Office, District of Massachusetts. In connection with Omnicare’s participation in Medicare, Medicaid and other healthcare programs, the Company is subject to various inspections, audits, inquiries and investigations by governmental/regulatory authorities responsible for enforcing the laws and regulations to which the Company is subject. Further, the Company maintains a compliance program which establishes certain routine periodic monitoring of the accuracy of the Company’s billing systems and other regulatory compliance matters and encourages the reporting of errors and inaccuracies. As a result of the compliance program, Omnicare has made, and will continue to make, disclosures to the applicable governmental agencies of amounts, if any, determined to represent over-payments from the respective programs and, where applicable, those amounts, as well as any amounts relating to certain inspections, audits, inquiries and investigations activity are included in “Settlement, litigation and other related charges” of the Consolidated Statements of Income. During 2006, the Company experienced certain quality control and product recall issues, as well as fire damage, at one of its repackaging facilities. In connection with the resolution of these matters (the “Repack Matters”) the Company decided not to reopen this facility. The Company has been cooperating with federal and state officials who have been conducting investigations relating to the Repack Matters and certain billing issues. Addressing these issues served to increase costs. The Company maintains product recall, property and casualty and business interruption insurance. The Company received insurance recoveries, net of increased costs in the 2010 and 2009 periods, of approximately $(10.5) million, $(1.2) million and $(1.1) million for the years ended December 31, 2011, 2010 and 2009, respectively. Although the Company cannot know the ultimate outcome of the matters described in the preceding paragraphs other than as disclosed, there can be no assurance that the resolution of these matters will not have a material adverse impact on the Company’s consolidated results of operations, financial position or cash flows or, in the case of other billing matters, that these matters will be resolved in an amount that would not exceed the amount of the pretax charges previously recorded by the Company. As part of its ongoing operations, the Company is subject to various inspections, audits, inquiries, investigations and similar actions by third parties, as well as governmental/regulatory authorities responsible for enforcing the laws and regulations to which the Company is subject. Further, under the federal False Claims Act, private parties have the right to bring qui tam, or “whistleblower,” suits against companies that submit false claims for payments to, or improperly retain overpayments from, the government. Some states have adopted similar state whistleblower and false claims provisions. The Company from time to time receives government inquiries from federal and state agencies regarding compliance with various healthcare laws. In addition, the Company is also involved in various legal actions arising in the normal course of business. At any point in time, the Company is in varying stages of discussions on these matters. Omnicare records accruals for such contingencies to the extent that the Company concludes that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These matters are continuously being evaluated and, in many cases, are being contested by the Company and the outcome is not predictable. The inherently unpredictable nature of legal proceedings may be exacerbated by various factors from time to time, including: (i) the damages sought in the proceedings are unsubstantiated or indeterminate; (ii) discovery is not complete; (iii) the proceeding is in its early stages; (iv) the matters present legal uncertainties; (v) there are significant facts in dispute; (vi) there are a large number of parties (including where it is uncertain how liability, if any, will be shared among multiple defendants); or (vii) there is a wide range of potential outcomes. Consequently, no estimate of the possible loss or range of loss in excess of the amounts accrued, if any, can be made at this time regarding the matters described above. Further, there can be no assurance that the ultimate resolution of these matters, individually or in the aggregate, will not have a material adverse effect on the Company’s consolidated results of operations, financial position or cash flows. The Company indemnifies the directors and officers of the Company for certain liabilities that might arise from the performance of their job responsibilities for the Company. Additionally, in the normal course of business, the Company enters into contracts that contain a variety of representations and warranties and which provide general indemnifications. The Company’s maximum exposure under these arrangements is unknown, as this involves the resolution of claims made, or future claims that may be made, against the Company, its directors and/or officers, the outcomes of which is unknown and not currently predictable. Accordingly, no liabilities have been recorded for the indemnifications.

Commitments and Contingencies

Omnicare continuously evaluates contingencies based upon the best available information. The Company believes that liabilities have been recorded to the extent necessary in cases where the outcome is considered probable and reasonably estimable. To the extent that resolution of contingencies results in amounts that vary from the Company’s recorded liabilities, future earnings will be charged or credited accordingly.

On October 5, 2011, a qui tam complaint, entitled United States ex rel. Donald Gale v. Omnicare, Inc., No. 1:10-cv-0127, was served on the Company. The case had been filed on January 19, 2010 under seal with the U.S. District Court for the Northern District of Ohio, Eastern Division. The complaint was unsealed by the Court on June 9, 2011 after the U.S. Department of Justice notified the court that it has declined to intervene in this action. The complaint was brought by Donald Gale as a private party qui tam relator on behalf of the federal government. The action alleges civil violations of the False Claims Act based on allegations that the Company provided certain customer facilities with discounts and other forms of remuneration in return for referrals of business in violation of the Anti-Kickback Statute, and offered pricing terms in violation of the "most favored customer" pricing laws of various state Medicaid plans. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action if pursued.

On August 4, 2011, a qui tam complaint, entitled United States of America ex rel. Fox Rx, Inc. v. Omnicare, Inc. and Neighborcare, Inc., No. 1:11-cv-0962, that was filed under seal with the U.S. District Court for the Northern District of Georgia, was unsealed by the Court. The U.S. Department of Justice has declined to intervene in this action. The Company has not been served with the complaint in this action. The complaint was brought by Fox Rx, Inc. as a qui tam relator on behalf of the federal government. The action alleges civil violations of the False Claims Act based on allegations that the Company billed Medicare Part D for medically unnecessary antipsychotic drugs, increased the dispensing fees by artificially shortening the supply of prescribed medication, submitted claims for antipsychotic drugs without complying with Fox Rx, Inc.’s prior approval requirements, and waived or failed to collect copayments from patients to induce the use of prescription drugs. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action if pursued.

On August 24, 2011, a class action complaint entitled Ansfield v. Omnicare, Inc., et al. was filed on behalf of a putative class of all purchasers of the Company's common stock from January 10, 2007 through August 5, 2010 against the Company and certain of its current and former officers in the United States District Court for the Eastern District of Kentucky, alleging violations of federal securities law in connection with alleged false and misleading statements with respect to the Company's compliance with federal and state Medicare and Medicaid laws and regulations. On October 21, 2011, a class action complaint entitled Jacksonville Police & Fire Pension Fund v. Omnicare, Inc. et al. was filed on behalf of the same putative class of purchasers as is referenced in the Ansfield complaint, against the Company and certain of its current and former officers, in the U.S. District Court for the Eastern District of Kentucky. Plaintiffs allege substantially the same violations of federal securities law as are alleged in the Ansfield complaint. Both complaints seek unspecified money damages. Motions for the appointment of lead plaintiff and lead counsel in these cases have been filed, fully briefed and argued and are awaiting decision, following which a consolidated amended complaint is expected to be filed. The Company believes that the claims asserted are without merit and intends to defend against them vigorously.

On December 13, 2010, a qui tam complaint entitled United States ex rel. Bartz v. Ortho-McNeil Pharmaceuticals, Inc., Johnson & Johnson, Janssen Pharmaceutica, Inc., Janssen Pharmaceutica Products, LP, McKesson Corporation, McKesson Specialty Pharmaceutical, LLC and Omnicare, Inc., Civil Action No. 05-cv-6010, which had been filed under seal with the U.S. District Court in Philadelphia, Pennsylvania, was ordered unsealed by the court. The complaint was brought by Scott Bartz, a former employee of Johnson & Johnson, as a private party qui tam relator on behalf of the federal government and several state and local governments. The U.S. Department of Justice has notified the court that it has declined to intervene. The action alleges civil violations of the False Claims Act based on allegations that Johnson & Johnson and its affiliates provided the Company and McKesson with rebates, free drugs and other remuneration in order to limit Johnson & Johnson’s rebate liability to Medicaid. The court granted Johnson & Johnson’s motion to transfer the action to U.S. District Court in Boston, Massachusets in February 2011. The Company filed a motion to dismiss the complaint on May 27, 2011. On June 10, 2011, the relator filed a notice of intent to voluntarily dismiss its claims against the Company, which is pending. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action if pursued.

On September 15, 2010, Omnicare entered into settlement agreements, without any finding of wrongdoing or admission of liability, with the State of Michigan, the Commonwealth of Massachusetts and David M. Kammerer ("Relator"), relating to sealed qui tam litigation originally filed by Relator in Ohio federal court in August 2003. The Company has paid $11.6 million pursuant to the Michigan settlement agreement and $9.45 million pursuant to the Massachusetts settlement agreement to resolve allegations of inappropriate billing, beginning in August 1997, under the states' usual and customary charge provisions. The Company has paid Relator's expenses and attorneys' fees of $385,000. The Company recorded provisions of $24.2 million for these payments, and a separate unrelated matter with another state which is still under review, in the quarter ended June 30, 2010.

On October 29, 2010, a qui tam complaint entitled United States ex rel. Banigan and Templin, et al. v. Organon USA, Inc., Omnicare, Inc. and Pharmerica, Inc., Civil No. 07-12153-RWZ, that had been filed under seal with the U.S. District Court in Boston, Massachusetts, was ordered unsealed by the court. The complaint was brought by James Banigan and Richard Templin, former employees of Organon, as private party qui tam relators on behalf of the federal government and several state and local governments. The action alleges civil violations of the False Claims Act based on allegations that Organon USA, Inc. and its affiliates paid the Company and several other long-term care pharmacies rebates, post-purchase discounts and other forms of remuneration in return for purchasing pharmaceuticals from Organon and taking steps to increase the purchase of Organon's drugs in violation of the Anti-Kickback Statute. The U.S. Department of Justice has notified the court that it has declined to intervene in this action. The Company filed a motion to dismiss the complaint on July 7, 2011. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action if pursued.

The Drug Enforcement Administration ("DEA") is investigating alleged errors and deficiencies in paperwork requirements for controlled substance dispensing at several of the Company's pharmacies in Ohio. The United States Attorney's Office, Northern District of Ohio ("AUSA"), is conducting an investigation relating to this matter, and may seek monetary penalties. The AUSA is also conducting a criminal investigation of several current and former employees in connection with the DEA audits. The Company is cooperating with these investigations and intends to vigorously defend itself if these matters are pursued. The Company recorded a provision for this matter in the quarters ended December 31 and June 30, 2011 and December 31, 2010. The Company is no longer the subject of a criminal investigation by the AUSA in connection with the DEA audits.

On April 14, 2010, a purported shareholder derivative action, entitled Manville Personal Injury Settlement Trust v. Gemunder, et al., Case No. 10-CI-01212, was filed in Kentucky State Court, against members of the Board and certain current and former officers of the Company, individually, purporting to assert claims for breach of fiduciary duty, unjust enrichment, gross mismanagement, and waste of corporate assets arising out of alleged violations of federal and state laws prohibiting the payment of illegal kickbacks and the submission of false claims in connection with the Medicare and Medicaid healthcare programs. Plaintiff alleges that the Board and senior management caused the company to violate these laws, which has resulted in over $100 million in fines and penalties paid by Omnicare and exposed the Company and certain individual defendants to potential civil and criminal liability. On April 27, 2011 the court entered an order denying defendants’ motion to dismiss the complaint for failure to make a pre-suit demand and failure to state a claim. Defendants filed a notice of appeal from the decision in the Kentucky Court of Appeals, and plaintiff moved to dismiss that appeal on the grounds that the order denying defendants’ motion to dismiss is not subject to an immediate appeal under Kentucky law. On October 6, 2011, the Kentucky Court of Appeals granted plaintiff’s motion on the grounds that the appeal was premature. The case is now in the discovery stage. The individual defendants have denied all allegations of wrongdoing, believe the claims against them to be completely without merit and intend to vigorously defend themselves in this action.

On April 2, 2010, a purported class action lawsuit, entitled Spindler, et al. v. Johnson & Johnson Corp., Omnicare, Inc. and Does 1-10, Case No. CV-10-1414, was filed in the United States District Court for the Northern District of California, San Francisco Division, against Johnson & Johnson (“J&J”), the Company and certain unnamed defendants asserting violations of federal antitrust law and California unfair competition law arising out of certain arrangements between J&J and the Company. Plaintiffs allege, among other things, that the Company violated these laws by entering into agreements with J&J to promote J&J products. On January 21, 2011, the court dismissed the amended complaint and granted permission to file a new amended complaint, which was filed in February 2011. On August 1, 2011, the court dismissed the second amended complaint and, on October 25, 2011, after plaintiffs had declined the court's invitation to further amend the complaint, the district court dismissed the matter with prejudice. Plaintiffs have filed a notice of appeal with the Ninth Circuit Court of Appeals. Briefing of the appeal is scheduled to be completed by April 9, 2012. The Company believes the claims to be entirely without merit and intends to vigorously defend the dismissal of those claims on appeal.

On January 8, 2010, a qui tam complaint, entitled United States ex rel. Resnick and Nehls v. Omnicare, Inc., Morris Esformes, Phillip Esformes and Lancaster Ltd. d/b/a Lancaster Health Group, No. 1:07cv5777, that was filed under seal with the U.S. District Court in Chicago, Illinois was unsealed by the court. The U.S. Department of Justice and the State of Illinois have notified the court that they have declined to intervene in this action. The complaint was brought by Adam Resnick and Maureen Nehls as private party “qui tam relators” on behalf of the federal government and two state governments. The action alleges civil violations of the False Claims Act and certain state statutes based on allegations that Omnicare acquired certain institutional pharmacies at above-market rates in violation of the Anti-Kickback Statute and applicable state statutes. On December 1, 2010, Resnick filed a motion to withdraw as a relator, which the court granted on December 14, 2010. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action.

On or about March 12, 2010, a qui tam complaint entitled State of Illinois, ex rel. Adam B. Resnick and Maureen Nehls v. Omnicare, Inc. Morris Esformes, Phillip Esformes, and Tim Dacy, No. D6 L 1926 that was filed under seal in Illinois state court, was unsealed by the court. The State of Illinois notified the court that it declined to intervene in the action. This complaint was brought by the same two qui tam relators, Adam Resnick and Maureen Nehls, that brought the complaint in the United States District Court in Chicago described above. This complaint is based on allegations nearly identical to a portion of the allegations contained in that federal action. The Company has not been served with the complaint in this action. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action if pursued.

On June 11, 2010, a qui tam complaint, entitled United States ex rel. Stone v. Omnicare Inc., No. 1:09cv4319, that was filed under seal with the U.S. District Court in Chicago, Illinois was unsealed by the court. The U.S. Department of Justice and the various states named in the complaint have notified the court that they have declined to intervene in this action. The complaint was brought by John Stone, the Company’s former Vice President of Internal Audit, as a private party qui tam relator on behalf of the federal government and several state governments. The action alleges civil violations of the False Claims Act and certain state statutes based on allegations that the Company submitted claims for reimbursement for certain ancillary services that did not conform with Medicare and Medicaid regulations, submitted claims for reimbursement from newly acquired pharmacies that were in violation of certain Medicaid and Medicare regulations, violated certain FDA regulations regarding the storage and handling of a particular drug, and violated certain Medicaid billing regulations relating to usual and customary charges. Relator also asserts against the Company a retaliatory discharge claim under the False Claims Act. On November 1, 2010, the Company filed a motion to dismiss the lawsuit. Relator responded and conceded to dismissal of one of the counts. On July 7, 2011, the court granted the Company's motion in part and denied it in part. The court granted the motion as to the allegations that the Company submitted claims for reimbursement for certain ancillary services that did not conform with Medicare and Medicaid regulations and submitted claims for reimbursement from newly acquired pharmacies that were in violation of certain Medicaid and Medicare regulations; the court dismissed those counts without prejudice. The court denied the Company's motion as to the allegations that the Company violated certain FDA regulations regarding the storage and handling of a particular drug and retaliated against Relator. On September 15, 2011, Relator filed an Amended Complaint. He repeated his claim that the Company submitted false claims for certain ancillary services that did not conform with Medicare and Medicaid regulations. Relator also asserted a claim in the Amended Complaint that the Company submitted false claims to the Nevada Medicaid program for a particular drug. Relator repeated his retaliatory discharge claim. The Company filed a motion to dismiss the Amended Complaint on November 15, 2011. The Relator has filed a response in opposition to that motion. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action.

On November 19, 2010, the Company was served with a second amended qui tam complaint entitled United States ex rel. Rostholder v. Omnicare, Inc. and Omnicare Distribution Center, LLC f/k/a Heartland Repack Services LLC, No. CCB-07-1283, that was filed under seal with the U.S. District Court in Baltimore, Maryland in July 2009. The U.S. Department of Justice notified the court on April 22, 2009 that it declined to intervene in this action. The complaint was brought by Barry Rostholder as a private party qui tam relator on behalf of the federal government and several state and local governments. The action, in general, alleges civil violations of the False Claims Act based on allegations that the Company submitted claims for reimbursement for drugs that were repackaged at its Heartland repackaging facility in violation of certain FDA regulations. These allegations arise from the previously disclosed issues experienced by the Company at its Heartland repackaging facility, which suspended operations in 2006. On September 30, 2011, the Company filed a motion to dismiss the lawsuit in its entirety, which has now been fully briefed. The Company believes that the claims in the complaint are without merit and intends to vigorously defend itself in this action if pursued.

As part of the previously disclosed civil settlement agreement entered into by the Company with the U.S. Attorney’s Office, District of Massachusetts in November 2009, the Company also entered into an amended and restated corporate integrity agreement (“CIA”) with the Department of Health and Human Services Office of the Inspector General with a term of five years from November 2, 2009. Pursuant to the CIA, the Company is required, among other things, to (i) create procedures designed to ensure that each existing, new or renewed arrangement with any actual or potential source of health care business or referrals to Omnicare or any actual or potential recipient of health care business or referrals from Omnicare does not violate the Anti-Kickback Statute, 42 U.S.C. (§) 1320a-7b(b) or related regulations, directives and guidance, including creating and maintaining a database of such arrangements; (ii) retain an independent review organization to review the Company’s compliance with the terms of the CIA and report to OIG regarding that compliance; and (iii) provide training for certain Company employees as to the Company’s requirements under the CIA. The requirements of the Company’s prior corporate integrity agreement obligating the Company to create and maintain procedures designed to ensure that all therapeutic interchange programs are developed and implemented by Omnicare consistent with the CIA and federal and state laws for obtaining prior authorization from the prescriber before making a therapeutic interchange of a drug and to maintain procedures for the accurate preparation and submission of claims for federal health care program beneficiaries in hospice programs, have been incorporated into the amended and restated CIA without modification. The requirements of the CIA have resulted in increased costs to maintain the Company’s compliance program and greater scrutiny by federal regulatory authorities. Violations of the corporate integrity agreement could subject the Company to significant monetary penalties. Consistent with the CIA, the Company is reviewing its contracts to ensure compliance with applicable laws and regulations. As a result of this review, pricing under certain of its consultant pharmacist services contracts have been increased and will continue to be increased, and these price increases have resulted and may continue to result in the loss of certain contracts.

In February 2006, two substantially similar putative class action lawsuits were filed in the United States District Court for the Eastern District of Kentucky, and were consolidated and entitled Indiana State Dist. Council of Laborers & HOD Carriers Pension & Welfare Fund v. Omnicare, Inc., et al., No. 2:06cv26. The amended consolidated complaint was filed against Omnicare, three of its officers and two of its directors and purported to be brought on behalf of all open-market purchasers of Omnicare common stock from August 3, 2005 through July 27, 2006, as well as all purchasers who bought their shares in the Company's public offering in December 2005. The complaint contained claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (and Rule 10b-5) and Section 11 of the Securities Act of 1933 and sought, among other things, compensatory damages and injunctive relief. Plaintiffs alleged that Omnicare (i) artificially inflated its earnings (and failed to file GAAP-compliant financial statements) by engaging in improper generic drug substitution, improper revenue recognition and overvaluation of receivables and inventories; (ii) failed to timely disclose its contractual dispute with UnitedHealth Group Inc.; (iii) failed to timely record certain special litigation reserves; and (iv) made other allegedly false and misleading statements about the Company’s business, prospects and compliance with applicable laws and regulations. The defendants filed a motion to dismiss the amended complaint on March 12, 2007, and on October 12, 2007, the court dismissed the case. On November 9, 2007, plaintiffs appealed the dismissal to the United States Court of Appeals for the Sixth Circuit. On October 21, 2009, the Sixth Circuit Court of Appeals generally affirmed the district court's dismissal, dismissing plaintiff's claims for violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5. However, the appellate court reversed the dismissal for the claim brought for violation of Section 11 of the Securities Act of 1933, and returned the case to the district court for further proceedings. On December 30, 2010, plaintiffs filed a motion in the district court requesting permission to file a third amended complaint. On February 4, 2011, the defendants filed a motion to dismiss the sole remaining claim in plaintiff's second amended complaint. On July 14, 2011, the court granted both motions and deemed the third amended complaint filed. This complaint asserts a claim under Section 11 of the Securities Act of 1933 on behalf of all purchasers of Omnicare common stock in the December 2005 public offering. The new complaint alleges that the 2005 registration statement contained false and misleading statements regarding Omnicare's policy of compliance with all applicable laws and regulations with particular emphasis on allegations of violation of the federal anti-kickback law in connection with three of Omnicare's acquisitions, Omnicare's contracts with two of its suppliers and its provision of pharmacist consultant services. On August 19, 2011, the defendants filed a motion to dismiss plaintiffs' most recent complaint and on February 13, 2012 the court dismissed the case and struck the case from the docket.

On February 13, 2006, two substantially similar shareholder derivative actions, entitled Isak v. Gemunder, et al., Case No. 06-CI-390, and Fragnoli v. Hutton, et al., Case No. 06-CI-389, were filed in Kentucky State Circuit Court, Kenton Circuit, against the members of Omnicare’s board of directors, individually, purporting to assert claims for breach of fiduciary duty, abuse of control, gross mismanagement, waste of corporate assets and unjust enrichment arising out of the Company’s alleged violations of federal and state health care laws based upon the same purportedly improper generic drug substitution that is the subject of the federal purported class action lawsuits. The complaints seek, among other things, damages, restitution and injunctive relief. The Isak and Fragnoli actions were later consolidated by agreement of the parties. The Company believes that the allegations are without merit and intends to vigorously defend itself in this action.

The years ended 2011, 2010 and 2009 included a $55.7 million, $113.7 million and $77.4 million charge, respectively, reflected in “Settlement, litigation and other related charges” of the Consolidated Statements of Income, primarily for estimated litigation and other related settlements and associated professional expenses for resolution of certain regulatory matters with the federal government and various states, certain large customer disputes, the investigation by the federal government and certain states relating to drug substitutions; purported class and derivative actions against the Company and costs associated with the settlement of the investigation by the United States Attorney’s Office, District of Massachusetts. In connection with Omnicare’s participation in Medicare, Medicaid and other healthcare programs, the Company is subject to various inspections, audits, inquiries and investigations by governmental/regulatory authorities responsible for enforcing the laws and regulations to which the Company is subject. Further, the Company maintains a compliance program which establishes certain routine periodic monitoring of the accuracy of the Company’s billing systems and other regulatory compliance matters and encourages the reporting of errors and inaccuracies. As a result of the compliance program, Omnicare has made, and will continue to make, disclosures to the applicable governmental agencies of amounts, if any, determined to represent over-payments from the respective programs and, where applicable, those amounts, as well as any amounts relating to certain inspections, audits, inquiries and investigations activity are included in “Settlement, litigation and other related charges” of the Consolidated Statements of Income.

During 2006, the Company experienced certain quality control and product recall issues, as well as fire damage, at one of its repackaging facilities. In connection with the resolution of these matters (the “Repack Matters”) the Company decided not to reopen this facility. The Company has been cooperating with federal and state officials who have been conducting investigations relating to the Repack Matters and certain billing issues. Addressing these issues served to increase costs. The Company maintains product recall, property and casualty and business interruption insurance. The Company received insurance recoveries, net of increased costs in the 2010 and 2009 periods, of approximately $(10.5) million, $(1.2) million and $(1.1) million for the years ended December 31, 2011, 2010 and 2009, respectively.

Although the Company cannot know the ultimate outcome of the matters described in the preceding paragraphs other than as disclosed, there can be no assurance that the resolution of these matters will not have a material adverse impact on the Company’s consolidated results of operations, financial position or cash flows or, in the case of other billing matters, that these matters will be resolved in an amount that would not exceed the amount of the pretax charges previously recorded by the Company.

As part of its ongoing operations, the Company is subject to various inspections, audits, inquiries, investigations and similar actions by third parties, as well as governmental/regulatory authorities responsible for enforcing the laws and regulations to which the Company is subject. Further, under the federal False Claims Act, private parties have the right to bring qui tam, or “whistleblower,” suits against companies that submit false claims for payments to, or improperly retain overpayments from, the government. Some states have adopted similar state whistleblower and false claims provisions. The Company from time to time receives government inquiries from federal and state agencies regarding compliance with various healthcare laws. In addition, the Company is also involved in various legal actions arising in the normal course of business. At any point in time, the Company is in varying stages of discussions on these matters. Omnicare records accruals for such contingencies to the extent that the Company concludes that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These matters are continuously being evaluated and, in many cases, are being contested by the Company and the outcome is not predictable. The inherently unpredictable nature of legal proceedings may be exacerbated by various factors from time to time, including: (i) the damages sought in the proceedings are unsubstantiated or indeterminate; (ii) discovery is not complete; (iii) the proceeding is in its early stages; (iv) the matters present legal uncertainties; (v) there are significant facts in dispute; (vi) there are a large number of parties (including where it is uncertain how liability, if any, will be shared among multiple defendants); or (vii) there is a wide range of potential outcomes. Consequently, no estimate of the possible loss or range of loss in excess of the amounts accrued, if any, can be made at this time regarding the matters described above. Further, there can be no assurance that the ultimate resolution of these matters, individually or in the aggregate, will not have a material adverse effect on the Company’s consolidated results of operations, financial position or cash flows.

The Company indemnifies the directors and officers of the Company for certain liabilities that might arise from the performance of their job responsibilities for the Company. Additionally, in the normal course of business, the Company enters into contracts that contain a variety of representations and warranties and which provide general indemnifications. The Company’s maximum exposure under these arrangements is unknown, as this involves the resolution of claims made, or future claims that may be made, against the Company, its directors and/or officers, the outcomes of which is unknown and not currently predictable. Accordingly, no liabilities have been recorded for the indemnifications.
