Portfolio data is normalized using SEC Form 13F filings, including the Restatement filing (0001019056-15-000911, filed 2015.11.17). Although 0001019056-15-000911 is marked by the manager as a New Holdings filing, our automated system processes it as a Restatement filing.

From 2023-01-03 onward, the SEC requires values to be reported in nearest dollars. Earlier filings reported values in thousands; therefore, positions shown as $0 in older filings may represent actual values between $0–$999.
