Professional liability policies cover the services rendered by medical professionals, lawyers and accountants, among other professionals. Large corporations in a variety of industries, including technology, retail, and manufacturing, among others, also have E&O coverage to cover the services they perform for their clients or for other companies. Many E&O policies also include coverage for legal costs. For a professional or a business, E&O coverage is critical protection as the cost to defend a groundless allegation can be financially devastating to a company’s bottom line.
