Competition, page-108

I did a cursory google check on market size of both. DR horton is listed as 50Bil and CRH is about 59Bil, I know its not perfect, but market size wise they are probably close. Why FBR decides to "partner" with CRH instead. I suspect it could be becasue of the "blocks" they can supply. CRH is being listed as a building material supplier/manufacturer, compared to DRH as just a volume builder in the US.
I also suspect that CRH might also want this for europe as well. While DRH has no presence there.

If what I speculate is true, this does means in some ways FBR might have strategically picked not just their local/US partner, but also a potential global partner as well. Would be interesting to know if DRH has offered the similar terms to FBR for the US JV.
