Key Financial Metrics
As a Form 13F filing, this document reports equity holdings rather than the company's operational financial performance (revenue, profit, or cash flow). The filing discloses the following portfolio metrics:
- Total Value of Reported Holdings: $313,368,520
- Number of Holdings Reported: 2
- Other Included Managers: 0
Note: The filing text does not provide values for revenue, profit, margins, debt, or liquidity as these are not required in a 13F-HR report.
Material Changes
The filing text does not provide comparative data for the prior period, nor does it explicitly detail material changes in holdings versus the previous quarter. The report indicates it is a standard 13F Holdings Report, not an amendment or restatement.
Guidance, Outlook, and Risks
This filing type does not contain management commentary, forward-looking guidance, risk factors, or contingencies regarding the company's operations. It strictly lists reportable equity securities held by the manager.
Investor Verification Checklist
- Verify the specific identities of the 2 holdings comprising the $313.4 million portfolio, as the provided text only lists the aggregate count and value.
- Confirm whether this report represents the total equity holdings of the manager or if other managers report portions of the portfolio (the filing indicates "NONE" for other included managers).
- Check subsequent filings for the June 30, 2026 quarter to track changes in these specific positions.
