Regulatory Filings Classification · 1% confidence The document is a standalone summary table of 2025 non-operating fund occupancy and related-party fund transactions, including account balances and reasons, approved on April 10, 2026. It is not a full annual or interim report, not an earnings release or call transcript, and does not announce publication of a separate document. It is a specific financial disclosure that does not fit any of the specialized categories, so it falls under the fallback “Regulatory Filings” category.
