Martin Farley and Ashley Clark formed a limited liability company with an operating agreement that provided a salary allowance of $61,000 and $49000 to each member, respectively. In addition, the operating agreement specified an income-sharing ratio of 3:2 . The two members withdrew amounts equal to their salary allowances. Revenues were $668,000 and expenses were $52,000,for a net income of s148,000.
a. Determine the division of $148,000 net income for the year.
b. Provide journal entries to close the (1) revenues and expenses and (2) drawing accounts for the two members. For a compound transaction, if an amount box does not require an entry, leave it blank.
c. If the net income were less than the sum of the salary allowances, how would income be divided between the two members of the LLC?
