On March 1, year 1, a suit was filed against Dean Company for patent infringement. Dean's legal counsel believes an unfavorable outcome is probable, and estimates that Dean will have to pay between $500,000 and $900,000 in damages. However, Dean's legal counsel is of the opinion that $600,000 is a better estimate than any other amount in the range.
