1.1 California Department of Insurance (CDI)

The California Department of Insurance (CDI) is the state agency that regulates the property and casualty (P&C) insurance industry under the California Insurance Code (CIC). The Code is the master statute; CDI's implementing rules live in Title 10 of the California Code of Regulations (CCR). Together they govern who may sell insurance, how policies are worded, and how rates are set.

The Elected Insurance Commissioner

Unlike most state insurance regulators, California's Insurance Commissioner is elected directly by voters to a four-year term. California is one of only about 11 states with an elected commissioner; in the others the governor appoints the office. Election makes the Commissioner politically independent of the governor and directly accountable to the public.

The Commissioner is the chief executive of CDI and holds broad statutory authority:

Proposition 103 and Prior-Approval Rate Regulation

Proposition 103, approved by voters in 1988, is the single most important California-specific regulation tested on this exam. It transformed California from an "open competition" rating state into a prior-approval state: an insurer generally must file a rate and obtain the Commissioner's approval before using it for most personal P&C lines (auto, homeowners, etc.).

Key provisions of Prop 103:

• Prior approval of rates by CDI before they take effect.
• An initial 20% rate rollback on auto and other P&C lines when the measure passed.
• A mandatory Good Driver Discount of at least 20% for qualified drivers.
• The intervenor process, which lets consumer organizations formally challenge a rate filing and recover fees if they make a substantial contribution.
• The legal standard in CIC §1861.05: a rate may not be excessive, inadequate, or unfairly discriminatory.

The Three Mandatory Auto Rating Factors

Prop 103 requires private-passenger auto rates to weight three factors in this order of importance:

1. Driving safety record (must be the most important factor)
2. Annual mileage driven
3. Years of driving experience

Optional factors (such as marital status or, within limits, ZIP code/territory) may be used only after these three and may not outweigh them. ZIP code alone may not be the dominant factor.

Exam Tip: Memorize the three mandatory factors and their order. "Driving safety record, annual mileage, years of driving experience" is one of the most frequently tested California facts.

How CDI Is Organized

CDI carries out its mission through specialized divisions:

• Producer Licensing Bureau — processes broker-agent license applications and renewals.
• Rate Regulation Branch — reviews and approves P&C rate filings under Prop 103.
• Market Conduct Division — audits insurer underwriting and claims handling.
• Fraud Division — investigates suspected insurance fraud, working with district attorneys.
• Consumer Services Division — fields complaints and can order corrective action.

The California Insurance Guarantee Association (CIGA) is a separate statutory entity, not part of CDI, that pays covered P&C claims when an admitted insurer becomes insolvent.

Admitted vs. Non-Admitted Insurers

California draws a sharp line between two kinds of insurers, and the exam tests the consequences of each.

• Admitted (authorized) insurers hold a Certificate of Authority from CDI, file rates and forms with the Department, and pay into CIGA. If an admitted insurer fails, CIGA backstops covered claims (within statutory caps).
• Non-admitted (surplus lines) insurers are not licensed by CDI but may write coverage that the admitted market will not. They are placed through a licensed surplus line broker, and — critically — their policyholders have no CIGA protection. California requires a written disclosure (the "D-1" / surplus-line notice) warning the insured of this.

The California FAIR Plan

When wildfire or other risk makes basic property coverage unavailable in the standard market, the California FAIR Plan acts as the state's insurer of last resort. It is a syndicated pool of all admitted property insurers that offers a basic dwelling-fire policy. Producers should know the FAIR Plan is not a public agency and not free — it is an industry pool, and its policies are limited (often paired with a separate "difference in conditions" wrap policy for fuller coverage).

The Rate-Filing Process in Practice

Under Prop 103's prior-approval system, a typical filing moves through these steps:

1. The insurer submits a rate application with actuarial support to CDI.
2. The filing is posted publicly; intervenors (consumer groups) may request a hearing.
3. CDI's Rate Regulation Branch reviews the filing against the "not excessive, inadequate, or unfairly discriminatory" standard.
4. The Commissioner approves, modifies, or disapproves the rate before it may be used.

This is why California rate changes can lag the rest of the country — every personal-lines change passes through CDI first.
