The most common sharing percentage is 50/50 but can sometimes go higher (e.g., 70 insurer/30 insured). The effect of such clauses is to reduce the amount of indemnity and defense costs that an insured could potentially incur if it refuses to consent to a settlement amount recommended by an insurer. This clause is an alternative to the standard hammer clause found within professional, directors and officers (D&O), and errors and omissions (E&O) policy forms.
