Baron Generational Growth Fund on Arch Capital Group Ltd.

Thesis

The Fund believes the current softening of the property and casualty insurance market is a temporary part of the normal insurance cycle rather than a structural problem for Arch Capital. Although premium pricing has flattened or declined in some lines as additional capital enters the market, Arch continues to grow written premiums and book value per share. The company benefits from high returns on equity, market share gains, disciplined underwriting, and attractive capital allocation. The Fund expects premium growth to reaccelerate when the insurance cycle turns and believes Arch's valuation multiple should expand alongside that improvement.

We are confident that as the cycle inevitably turns again, premium growth will reaccelerate, and both stocks' multiples will expand.
