Amy and Mitchell are equal partners in the accrual basis AM Partnership. At the beginning of the current year, Amy’s capital account has a balance of $300,000, and the partnership has recourse debts of $200,000 payable to unrelated parties. Assume that all partnership recourse debt is shared equally between the partners. The following information about AM’s operations for the current year is obtained from the partnership’s records.

Charitable contribution                              4,000
