In 2000, Hatch launched a year-long compliance review of Allina Health System, the state's largest hospital system. Allina at the time owned Medica Health Plans, one of the state's largest HMOs. Allina and Medica are nonprofit organizations. Hatch launched his probe under the nonprofit laws after the federal Centers for Medicare and Medicaid Services found that an unnamed Minnesota nonprofit HMO had spent Medicare premium revenue on sports tickets and other lavish perks for executives. When Allina refused to cooperate with the compliance review, Hatch sued it to gain access to its books and records. He ultimately issued a multi-volume compliance report with hundreds of adverse findings against the organization. Among other things, the review found that top executives at the company spent tens of millions of dollars on golf trips, parties, beachfront condominiums, maid service for executives, spas, image consultants, executive enrichment and unearned executive bonuses, foreign travel, consultants, and gifts. Hatch issued a report stating that conflicts of interest within the organization resulted in Medica HMO's premium dollars being diverted to shore up the financial position of Allina's corporate headquarters, resulting in higher premiums for policyholders.
