As with Everpure, we trimmed the position on the outperformance, but the investment remains a top idea in the portfolio.
we reduced investment exposure to the group, including CrowdStrike and Cloudflare, selling into strength as we manage the risk reward opportunity in the portfolio.

This incremental regulatory risk caused us to moderate the investment position size, but we retained exposure to the company.
We eliminated the investment in the quarter as the stock exceeded our view of fair value and believe better risk-reward opportunities exist within Semiconductors.
We chose to close our position in the quarter and continued the process of repositioning software weight to the most durable competitive positions and clearest AI beneficiaries we can identify.
