When Mr. Green Teа first stаrted their business = it sоld its "green teа" flavоred ice cream sоlely to two large Asian-cuisine restaurant chains in the northern New Jersey region. These two restaurant chains accounted for 100% of Mr. Green Tea's sales (50% and 50% respectively). As such, Mr. Green Tea did not have much leverage when it came to contract negotiations, since these two customers accounted for all of their sales. Over the years, the company has expanded their customer base. Now Mr. Green Tea has contracts with over 50 different restaurant chains located in New Jersey and New York. Additionally, the company now sells individual cartons of its ice cream to retail store customers; and has its products for sale in over 10 different grocery store chains in the New Jersey and New York region. This change in business model is an example of which type of risk treatment option?
