Errors & Omissions (E&O)

Errors and Omissions insurance protects companies and individuals against loss (damages and defense costs) resulting from acts, errors or omissions in their performance of professional duties. Common claims allege negligence, misrepresentation, design errors, violation of good faith and fair dealing and inaccurate advice.

Errors and Omissions insurance, also known as professional liability insurance, helps protect your assets where your general liability policy does not. Often, general liability policies do not cover specific exposures that could lead to devastating judgments. Errors and Omissions protects against claims of negligence or mistakes that cause financial harm to another person or company, and covers both the obligation to pay damages along with the cost to defend. If your company provides professional services directly to individuals or other companies then you need Professional Liability insurance.
