On November 14, 2025, the Colorado Department of Regulatory Agencies (DORA) issued Bulletin No. B-10.005 to address inquiries about the manner and format of the interim report required by Colorado Insurance Regulation 10-1-1 for private passenger auto insurers that use external consumer data and information sources (ECDIS), or algorithms or predictive models that use ECDIS.

The bulletin states that insurers may submit the report in a format that suits their documentation preferences as long as it addresses the requirements outlined in the regulation. The DORA provides some information that can be included, such as an executive summary and expected completion date. The report should be submitted through SERFF filing access no later than December 1, 2025.
