Warren Buffett eyes Groupon

(Crain's) — Renowned investor Warren Buffett will read Groupon Inc.'s filings for an initial public offering, according to a report.

Mr. Buffett told Bloomberg TV he hopes to buy another company this year and that Chicago-based Exelon Corp. and Decatur-based Archer Daniels Midland Co. are the types of firms that interest him.

He declined to comment on specific targets to Bloomberg TV.

Chicago-based Groupon, a daily-deal coupon site, filed last month for an IPO.
