For an annual risk-section review, BamSEC’s document comparison provides a view of document changes. RiskDiff organizes the review around individual factors: start with added, removed or modified factors, inspect their exact edits, and follow the company through available comparison history. SEC source links let you check a passage in its original context.
To follow a topic, BamSEC documents search and search alerts. RiskDiff’s Signals groups keyword matches for defined themes such as AI, cybersecurity and tariffs across cached comparisons. From a match, open the underlying disclosure and use Pro’s individual exports or API-key MCP access to bring the comparison into your notes or compatible agent.
Copart (CPRT) · 2025 vs 2024
Example: what changed in Copart’s 10-K
This example shows one edit within Copart’s risk factor about expansion outside the U.S. RiskDiff matches the factor across filings and marks it as modified. The added wording is highlighted in green.
Before · 2024 10-K
the need to comply with complex foreign and U.S. laws and regulations that apply to our international operations;
After · 2025 10-K
the need to comply with complex foreign and U.S. laws and regulations that apply to our international operations, including changes in laws that may have an adverse effect on our ability to operate our preferred business model in foreign jurisdictions;
The added qualification concerns changes in laws affecting the company’s preferred business model abroad. The earlier filing already discussed foreign-law compliance. This edit does not show that international regulatory risk was new, or establish its investment significance.
RiskDiff groups this edit within the matched international-expansion risk factor. For this pair, the comparison identifies 15 modified and 19 unchanged factors, with none added or removed.
