insolvency
Insolvency is a financial condition in which a debtor cannot satisfy their obligations, or has liabilities that exceed the value of their assets. Depending on the statute and context, distinct legal tests are used to determine insolvency. Some apply a balance sheet test, asking whether the debts exceed the fair market value of the debtor's property or assets. Others use a cash-flow or ability-to-pay test, asking whether the debtor has ceased paying debts in the ordinary course of business or cannot pay debts as they become due.
In federal bankruptcy law, Bankruptcy Code § 101(32) defines “insolvent” differently depending on the type of debtor. For most entities other than partnerships and municipalities, insolvency generally means that the entity’s debts are greater than all of its property at a fair valuation, excluding certain property described in the statute. Partnerships have a special rule that considers partnership property and the excess value of general partners’ non-partnership property. For a municipality, insolvency focuses on whether the municipality is generally not paying (or is unable to pay) its debts as they become due.
In commercial law, UCC § 1-201(b)(23) there are alternative tests. A person may be deemed insolvent if they have generally ceased to pay debts in the ordinary course of business, other than because of a bona fide dispute; is unable to pay debts as they become due; or is insolvent within the meaning of federal bankruptcy law. Because these tests ask different questions, a person or business may satisfy one insolvency test but not another.
Insolvency is distinct from bankruptcy. Insolvency is a financial condition (or, in some statutes, a defined legal status), whereas bankruptcy is a federal judicial proceeding under Title 11 of the U.S. Code. An insolvent debtor has not necessarily filed a bankruptcy case, and a bankruptcy case may involve issues other than insolvency.
Determining insolvency can affect the rights of creditors and the validity of transactions. In bankruptcy, Bankruptcy Code § 547 allows for the avoidance of certain preferential transfers, and the debtor is presumed insolvent during the 90 days preceding the bankruptcy filing. Bankruptcy Code § 548 also uses insolvency when determining whether certain transfers or obligations may be avoided as constructively fraudulent transfers. Other state and commercial laws may also attach consequences to insolvency.
An insolvency analysis therefore usually starts by identifying the applicable law, the type of debtor, the relevant date, and whether the issue concerns asset value, payment ability, or the effect of a particular transfer or distribution.
