Professional Liability Insurance
Professional liability insurance (PLI), also called professional indemnity insurance (PII) but more commonly known as errors & omissions (E&O) in the US, is a form of liability insurance that helps protect professional advice- and service-providing individuals and companies from bearing the full cost of defending against a negligence claim made by a client, and damages awarded in such a civil lawsuit. The coverage focuses on alleged failure to perform on the part of, financial loss caused by, and error or omission in the service or product sold by the policyholder. These are potential causes for legal action that would not be covered by a more general liability insurance policy which addresses more direct forms of harm. Professional liability coverage sometimes also provides for the defense costs, including when legal action turns out to be groundless.
Coverage does not include criminal prosecution, or a wide range of potential liabilities under civil law that are not enumerated in the policy, but which may be subject to other forms of insurance. Professional liability insurance is required by law in some areas for certain kinds of professional practice (especially medical and legal), and is also sometimes required under contract by other businesses that are the beneficiaries of the advice or service.
Professional liability insurance may take on different forms and names depending on the profession. For example, in reference to medical professions it is called malpractice insurance, while errors and omissions (E&O) insurance is used by consultants, brokers and lawyers. Other professions that commonly purchase professional liability insurance include accounting and financial services, construction and maintenance (general contractors, plumbers, etc., many of whom are also surety bonded), and transport. Some charities and other nonprofits/NGOs are also professional-liability insured.
Errors and omissions (E&O) insurance, which may exclude negligent acts other than errors and omissions ("mistakes"), is most often used by consultants and brokers and agents of various sorts, including notaries public, real estate brokers, insurance agents themselves, appraisers, management consultants and information technology service providers (there are specific E&O policies for software developers, website developers, etc.), architects, landscape architects, engineers, attorneys, third-party business administrators, quality control specialists, nondestructive testing analysts, and many others. A mistake which causes financial harm to another can occur in almost any transaction in many professions.
Bond insurance (also known as "financial guaranty insurance") is a type of insurance whereby an insurance company guarantees scheduled payments of interest and principal on a bond or other security in the event of a payment default by the issuer of the bond or security.
As compensation for its insurance, the insurer is paid a premium (as a lump sum or in installments) by the issuer or owner of the security to be insured. Bond insurance is a form of "credit enhancement" that generally results in the rating of the insured security being the higher of (i) the claims-paying rating of the insurer and (ii) the rating the bond would have absent insurance (also known as the “underlying” or “shadow” rating).
The premium requested for insurance on a bond is a measure of the perceived risk of failure of the issuer. It can also be a function of the interest savings realized by an issuer from employing bond insurance or the increased value of the security realized by an owner who purchased bond insurance.
