though he was effectively the only person

Corporate insolvencies happen because companies become excessively indebted. Under UK law, a company is a separate legal person from the people who have invested money and labour into it, and it mediates a series of interest groups.[15] Invariably the shareholders, directors and employees' liability is limited to the amount of their investment, so against commercial creditors they can lose no more than the money they paid for shares, or their jobs. Insolvencies become intrinsically possible whenever a relationship of credit and debt is created, as frequently happens through contracts or other obligations. In the section of an economy where competitive markets operate, wherever excesses are possible, insolvencies are likely to happen. The meaning of insolvency is simply an inability to repay debts, although the law isolates two main further meanings. First, for a court to order a company be wound up (and its assets sold off) or for an administrator to be appointed (to try to turn the business around), or for avoiding various transactions, the cash flow test is usually applied: a company must be unable to pay its debts as they fall due. Second, for the purpose of suing directors to compensate creditors, or for directors to be disqualified, a company must be shown to have fewer overall assets than liabilities on its balance sheet. If debts cannot be paid back to everybody in full, creditors necessarily stand in competition with one another for a share of the remaining assets. For this reason, a statutory system of priorities fixes the order among different kinds of creditor for payment.

The credit ratings industry is dominated by Fitch, Moody's and S&P, with London headquarters in Canary Wharf. Companies pay the rating agencies to rate them, because this provides access to cheaper loans.

Companies are legal persons, created by registering a constitution and paying a fee, at Companies House. Like a natural person, a company can incur legal duties and can hold rights. During its life, a company must have a board of directors, which usually hires employees. These people represent the company, and act on its behalf. They can use and deal with property, make contracts, settle trusts, or maybe through some misfortune commission torts. A company regularly becomes indebted through all of these events. Three main kinds of debts in commerce are, first, those arising through a specific debt instrument issued on a market (e.g. a corporate bond or credit note), second, through loan credit advanced to a company on terms for repayment (e.g. a bank loan or mortgage) and, third, sale credit (e.g. when a company receives goods or services but has not yet paid for them.[16] However, the principle of separate legal personality means that in general, the company is the first "person" to have the liabilities. The agents of a company (directors and employees) are not usually liable for obligations, unless specifically assumed.[17] Most companies also have limited liability for investors. Under the Insolvency Act 1986 section 74(2)(d) this means shareholders cannot be generally sued for obligations a company creates. This principle generally holds wherever the debt arises because of a commercial contract. The House of Lords confirmed the "corporate veil" will not be "lifted" in Salomon v A Salomon & Co Ltd. Here, a bootmaker was not liable for his company's debts even though he was effectively the only person who ran the business and owned the shares.[18] In cases where a debt arises upon a tort against a non-commercial creditor, limited liability ceases to be an issue, because a duty of care can be owed regardless. This was held to be the case in Chandler v Cape plc, where a former employee of an insolvent subsidiary company successfully sued the (solvent) parent company for personal injury. When the company has no money left, and nobody else can be sued, the creditors may take over the company's management. Creditors usually appoint an insolvency practitioner to carry out an administration procedure (to rescue the company and pay creditors) or else enter liquidation (to sell off the assets and pay creditors). A moratorium takes effect to prevent any individual creditor enforcing a claim against the company. so only the insolvency practitioner, under the supervision of the court, can make distributions to creditors.
