John G. Koch is a shareholder at Flaster Greenberg and a member of the Insurance Counseling and Recovery, Litigation, and Environmental Practice Groups. He is also the firm's Deputy General Counsel and leads the Attorney Development Program.

John helps business clients recover from their insurance companies or other responsible parties when facing a loss or potential liability. His clients come to him for cost-effective, objective-driven representation. He does not represent insurance companies.

Whether by litigating a case through trial and appeal, using alternative dispute resolution (ADR), or out-of-court negotiations, John has recovered substantial sums for clients under both liability insurance policies and property insurance policies. His clients hail from many industries, such as HVAC and other manufacturing, global food and beverage, big box retail and shopping centers, property management, communications and entertainment, publishing, financial services, and others.

John has represented policyholder clients in matters involving property damage and large business interruption losses, environmental and toxic tort liabilities (CERCLA and hazardous waste, asbestos, silica, hearing loss), business torts, advertising and other “Coverage B” or Media Liability matters, product and construction defects, product recalls, D&O, E&O, Fidelity/Crime, and bad faith.

John has also successfully advanced clients’ interests in the insurance claim process, helping to maximize recoveries and avoid or resolve coverage disputes (if possible) before having to resort to costly and disruptive litigation.

Several clients have tapped John's insurance counseling experience to help close M&A or property transactions that involve contingent liabilities, such as legacy asbestos or environmental issues. For example, John helped a publicly traded manufacturing client acquiring another business to understand and evaluate the target’s projected future asbestos contingent liability risk, the target’s insurance program, and the cost sharing arrangements with contributing insurers. John then assisted with negotiating risk transfer and indemnity provisions for the successful acquisition.

On the other side of a transaction, John assisted a manufacturing client with contingent asbestos liabilities sell a major business line by negotiating cost sharing agreements with insurers, establishing a Qualified Settlement Fund, and working with a specialty insurance broker to negotiate and place a contingent liability insurance policy. This risk transferring strategy enabled the transaction to close.

John has also helped manage legacy liability cost sharing programs under old general liability policies, which often name corporate predecessors as insureds.

John’s environmental practice dovetails with his insurance practice. His clients call upon him to prosecute and defend environmental contribution and cost recovery actions, provide counseling during site remediation, and negotiate with government regulators. John also assists clients with due diligence, risk transfer, and negotiations in transactions involving industrial or contaminated property.

At the helm of the firm's Attorney Development Program, John has organized a variety of educational opportunities for our shareholders and associates to foster financial success, professional well-being, well-roundedness, and a sense of balance. Workshops have included topics such as the fundamentals of building a book of business, how HR is an integral part of a firm and an attorney's success, the fundamentals of understanding a balance sheet, and more.

Representative Matters

  • Represented big box retailer in property loss insurance claim arising from Hurricane Maria involving 8 separate commercial buildings. Compelled client’s property insurer to pay an additional $15 million above its loss assessment without resorting to litigation.
