AlixPartners Economists Advise U.S. Department of Justice in Insurance Brokers Merger
An AlixPartners team, led by Dr. Tasneem Chipty, Laura Phillips Perkins, and Dr. Joseph Rossetti, advised the U.S. Department of Justice in its investigation and subsequent litigation of the proposed merger of Aon plc and Willis Towers Watson, two of the three largest global insurance brokers. The team’s analysis demonstrated the merger would reduce competition and lead to higher prices for broking and consulting services related to commercial risk management, reinsurance, health benefits, and retirement benefits, including private exchanges and pension services, for American businesses.
After the DOJ pursued litigation, the parties abandoned their $30 billion planned merger. Read Attorney General Merrick Garland’s statement here.
FTC v. Qualcomm and Apple v. Qualcomm
Managing Director Dr. Tasneem Chipty was one of Qualcomm’s antitrust experts in lawsuits challenging Qualcomm’s licensing practices and use of customer incentive agreements that reference rivals. She and the team studied issues of market definition, market power, and raising rivals costs—accounting for technological innovation in the dynamic modem chipset marketplace. Dr. Chipty also studied Qualcomm’s contracts with Apple, which the FTC characterized as exclusionary contracts.
Consistent with Dr. Chipty’s testimony, the 9th Circuit ruled in favor of Qualcomm (in FTC v. Qualcomm), drawing a distinction between “anticompetitive” and “hypercompetitive” behaviors and concluding that the Qualcomm-Apple contracts did not have an “actual or practical effect of substantially foreclosing competition in the CDMA modem chip market.”
CenturyLink-Level 3 Merger
Managing Director Dr. Tasneem Chipty led multiple teams to evaluate the competitive landscape for business data services, on behalf of the parties before the U.S. Department of Justice and Federal Communications Commission. The analysis involved assessing the overlap in the parties’ assets in several metropolitan areas and the likely response of rivals to the putative merger.
The deal cleared federal merger review in October 2017.
MOL, K-Line, and NYK Line Joint Venture
Managing Director Dr. Tasneem Chipty and her team analyzed the competitive effects of the formation of a joint venture between three Japanese shipping companies, on behalf of the parties. The assignment involved analyzing competition along the supply chain for transporting refrigerated produce between the U.S. and Japan. Dr. Chipty presented these findings before the U.S. Department of Justice in the summer of 2017.
The transaction was permitted to close in the U.S. without any conditions attached.
U.S., et al. v. Hillsdale Community Health Center, et al.

In addition, she analyzed the overlap of services offered by the hospitals and conducted a diversion analysis to assess whether the Defendants were competitors.
The dispute settled in February 2018 with the Defendants agreeing not to engage in the challenged conduct.
Liberty’s acquisition of AT&T’s Wireline and Wireless Assets in Puerto Rico and the U.S. Virgin Islands

Their work was submitted to both the DOJ and the FCC, who permitted the transaction to close, with divestitures, in October 2020.
U.S. et al. v. Carolinas Healthcare System
Managing Director Dr. Tasneem Chipty was the government’s antitrust expert in its lawsuit against Carolinas Healthcare System that challenged the steering restrictions CHS imposed on health insurers.

Disney divests regional sports networks in acquiring FOX assets
Disney sought regulatory approval to acquire FOX assets, including cable networks, film and television studios, and its 30 percent stake in Hulu. The U.S. Department of Justice conditionally approved the acquisition subject to Disney divesting 22 FOX regional sports networks. Our team supported an academic economist to evaluate the competitive implications of Disney’s proposed acquisition.
The amount of private antitrust litigation outside the U.S. continues to increase dramatically. This is no longer confined to the traditional jurisdictions of the UK, Germany and the Netherlands, but is now worldwide. Follow-on claims, which rely on a regulatory decision to prove an infringement, and stand-alone claims, where the infringement must be shown, are common. In the EU, virtually every cartel decision by a regulator is now followed by a damages claim from customers; and cartel damages claims are far from the only types of claim being brought.
AlixPartners Managing Director Mat Hughes discusses the key issues raised when valuing and arguing loss in private antitrust litigation outside the U.S., from both the claimants’ and defendants’ points of view.
