An Overview of 10 Professional Liability Insurance Companies

Below is a detailed review of this year’s top professional liability insurance companies and firms.

But first, let’s quickly go over what professional liability insurance really represents.

The Two Parts of Professional Liability Insurance (PLI)

What is professional liability insurance?

Professional liability insurance has two parts to it: (1) professional liability and (2) insurance.

1.Professional Liability: This covers the specific responsibilities that professionals take on when performing their designated roles. For instance, when an investment advisor signs up a client, he/she (the advisor) takes on the responsibility of providing good financial advice to the client. When a doctor takes on a patient, he/she has the responsibility of providing accurate and adequate care. The advisor or doctor is, therefore, professionally “liable” to deliver such advice or care, and his/her failure to do so can be deemed as negligent. 

2. Insurance: The term “insurance,” broadly speaking, refers to steps taken to acquire some protection against any kind of real or perceived actions or consequences. In the context of professional liability insurance, such protection is sought against possible consequences arising out of one’s professional conduct.

As illustrated in the diagram below (representing a hedge fund management company), professionals constantly face liability threats during the course of their work and from multiple sources.

The red lines illustrate the exposure that officers and directors of a firm face from claims arising out of a possible breach of duty.

Such exposure can come from shareholders, employees, creditors, and even customers of the firm. 

Given this huge exposure that they face, professionals involved in libelous work need some form of insurance.

Therefore, putting the sum of the parts together, we can answer the question (what is professional liability insurance?) as follows:

“It is insurance that professionals in many fields acquire to protect themselves against the consequences that might arise from conducting the business of their chosen profession.”

10 Professional Liability Insurance Companies and Firms

Except for a few professionals, most individuals delivering professional services (either directly as self-employed professionals or on behalf of an employer) opt to insure themselves against professional liability.

Professional liability insurance coverage, also known as professional indemnity insurance (PII) or errors & omissions (E&O) insurance is offered by firms specializing in the area of delivering such services.   

Like all businesses, professional liability insurers come in all different shapes and sizes.

Some are local entities while others are multinational corporations.

Others offer only a restricted range of coverage, while their peers offer a gourmet of coverage.

And, still, others might offer professional liability insurance coverage to a broad spectrum of companies, while their peers simply cover selective professionals –  like insurers or health service providers.

A Matter of Tradeoffs

Once business owners and leaders understand the answer to the question (what is professional liability insurance?), the next obvious question to follow with is: Do I need professional liability insurance?

And the answer is: Most likely, yes!

Like any other form of insurance coverage, professional liability insurance is all about making trade-offs between:

  • The likelihood that a libelous act of professional misconduct will happen
  • The cost of dealing with such acts


  • The cost of paying the premiums associated with acquiring professional liability insurance protection against the consequences of such acts

There is no easy answer as to whether one should get insured for professional liability.

The general rule of thumb for making the decision as to whether one should be insured or not usually comes down to:

  • Whether it is a general practice in the industry that many do business with
  • Whether clients, business partners, and financers expect a company they do business with to be insured
  • Whether the business environment is such that (even though peer groups may not deem it so) it is prudent to acquire professional liability insurance

Generally speaking, not all areas of a firm’s operations are susceptible to libelous actions. 

Another aspect of the trade-off, therefore, would be to decide what specific areas of the firm or which specific individuals should be insured.
