Today's broad range of exposures requires a flexible insurance solution. Chubb’s MasterKey property policy sets the industry standard with its modular format and range of options. No matter what your specific needs are, our policies have a modular format and range of options that can be crafted to fit them.

    • Ordinance or law (up to building, personal property, and business income limits)
    • Selling price on finished stock

    • Any other location
    • Exhibition, fair or trade show
    • Extra expense
    • Ingress and egress
    • Loss of utilities, including Internet
    • New product delay
    • Ordinance or law
    • Worldwide dependent business premises
  • Online Business Income/Extra Expense (BI/EE) calculator available to help clients estimate the appropriate limits of BI/EE insurance
  • Impairment of computer services and malicious programming addresses the emerging first-party exposures presented by the Internet

Global Approach

With MasterKey's global extension, your overseas operations receives the same quality protection as your domestic properties. Chubb can also write primary insurance in most countries, either through our own Chubb companies or correspondents overseas. When the MasterKey global extension is purchased, Chubb pays for losses in foreign jurisdictions in the currency requested.

When does a company need Chubb’s MasterKey property policy? Consider the following scenarios:

  • The refrigeration system in a pharmaceutical company's research department experiences electrical failure due to a power surge. Specimen samples that took weeks to develop are completely ruined. The $100,000 loss is paid under MasterKey's broad all-risk property/income perils insurance.
  • A wholesaler's key supplier has a fire at its facility. As a result, the supplier is unable to ship needed products and the wholesaler loses key customers. MasterKey's dependent business premises insurance helps protect the wholesaler from the resulting business income loss and extra expense it incurs.
