I found this for AT risk limitation
Deductible losses from a venture are limited to the amount that a taxpayer is actually risking from an economic standpoint. The taxpayer has an amount at-risk to the extent of cash or other personal assets that are subjected to the risks of the business venture. Specifically, a taxpayer's at-risk amount typically includes the following:
•The amount of money or other property that is contributed to the venture
•The amount of any liabilities for which the taxpayer is personally liable that relate to the investment
•An allocable share of nonrecourse debts incurred by the venture from third parties that relate to real estate activities
In addition to a venture or business, a taxpayer can be at-risk for a single expenditure.
At-risk rules apply to most trade or business activities, including activities conducted through a partnership or activities for the production of income. The at-risk rules limit the amount of loss a partner can deduct to only those amounts for which that partner is considered at risk in the activity.
A partner is generally not considered at risk for amounts borrowed unless that partner is personally liable for repayment, or the amounts borrowed are secured by the partner's property other than property used in the activity.
Additionally, a partner is not considered at risk for amounts protected against loss through guarantees, stop-loss agreements, or other similar arrangements; nor is the partner at risk for amounts borrowed if the lender has an interest in the activity (other than as a creditor) or if the lender is related to a person (other than the partner) having such an interest.
