## Questions

### Who makes the investment decisions at Thornmark?

Robert McWhirter, the firm's President and lead portfolio manager, is the key decision-maker. He runs the quantitative stock-selection model that drives the Renaissance Canadian Thematic Growth Pool and oversees the firm's other mandates. No investment committee or deputy manager structure has been publicly detailed.

### Does Thornmark manage private funds or only public-market strategies?

Thornmark primarily manages publicly offered pooled funds and separate accounts focused on listed Canadian equities. The Renaissance Canadian Thematic Growth Pool — a publicly available, daily-valued mutual fund — is its flagship vehicle. There is no public record of the firm operating private equity, venture capital, or private credit funds.

### How concentrated is the Renaissance Canadian Thematic Growth Pool?

The strategy maintains a concentrated book of 25 to 35 positions drawn from a screened universe of roughly 700 Canadian equities. Sector and single-stock weights are a function of the quantitative model's output rather than arbitrary diversification limits, though Canadian mutual fund regulations impose concentration constraints.

### Where is Thornmark's performance track record published?

The Renaissance Canadian Thematic Growth Pool's performance data and full portfolio holdings are publicly disclosed through Fundata Canada and Renaissance Investments' reporting channels. The strategy's track record extends back over two decades, reflecting McWhirter's long tenure running quantitative Canadian equity mandates beginning prior to Thornmark's current structure.
