Cleary, Wasser, and Nolan formed a partnership on January 1, 2010, with investments of $100,000, $150,000, and $200,000, respectively. For division of income, they agreed to (1) interest of 10% of the beginning capital balance each year, (2) annual compensation of $10,000 to Wasser, and (3) sharing the remainder of the income or loss in a ratio of 20% for Cleary, and 40% each for Wasser and Nolan.
