Insurance
Umbrella insurance is extra liability coverage that pays after the limits of an underlying policy — auto, homeowners, general liability, or employers liability — are exhausted. The declarations page lists the umbrella limit, the self-insured retention, and a schedule of the underlying policies it sits above.
A $1 million umbrella policy typically costs a few hundred dollars a year, with each additional million costing less than the first.

Overview
An umbrella policy is a second layer of protection: when a serious claim blows past the liability limit on your auto, home, or business policy, the umbrella pays the excess, typically in $1 million increments. Personal umbrellas sit over auto and homeowners policies; commercial umbrellas sit over general liability, commercial auto, and employers liability.
The document's defining feature is the schedule of underlying insurance — the list of policies (with carriers and limits) the umbrella requires you to maintain. Let an underlying policy lapse or drop below the required limit and you become responsible for the gap. The self-insured retention is what you pay when the umbrella responds to a claim no underlying policy covers.
These are the fields Granite reads and extracts automatically the moment you upload one.
How long to keep it
Keep every umbrella policy permanently, together with the underlying policies from the same period.
An umbrella only pays after an underlying policy's limit is exhausted, so any late-surfacing liability claim involves both documents from the year of the incident. Because liability suits can be filed years after the fact, the umbrella and its scheduled underlying policies from that period need to survive together — one without the other can't prove how the layers stacked.
Granite reads your umbrella declarations (carrier, policy number, occurrence and aggregate limits, self-insured retention, and the schedule of underlying insurance) and files it alongside the underlying policies it sits above. Every policy year stays searchable as a set, so when a claim reaches into a prior period you can pull the umbrella and its underlying policies together, and Granite reminds you before the term lapses.
