Great West Boating Ventures is a limited partnership formed to purchase and operate a fishing boat. The partnership was formed by two partners, I and L, who each contributed $150,000 cash to form the partnership. The partnership then borrowed $800,000 on a nonrecourse loan from an unrelated bank, and purchased a boat. The two partners share all items of partnership income, gain, loss and deduction equally.

Over the partnerships first 3 years of operations, it reported net losses of ($580,000), allocated equally between the two partners. It also made principal payments against the nonrecourse loan of $50,000. Assuming no distributions or additional contributions were made to or by the partners over that period, what will be the partners tax bases in their partnership interests at the end of year 3?
