you invested $x. that would be increased by any items of income that flowed through to you (like interest income). you received no distributions. this gives you your tax basis. thus over the life of the partnership, this would be the total losses you can deduct. ordinary losses would come first. if you have any tax basis left it would be a capital loss. what if you deducted more in losses than your tax basis. that would likely be ordinary income. I'm assuming the reason for negative capital is that debt gave the partnership the ability to incur more in losses than was invested. when the partnership terminates debt decreases producing ordinary income under the tax laws.
