( EXCO Resources item corrected to note shares were issued under private placements.) NEW YORK ( TheStreet) -- Two Harbors Investment ( TWO) lost ground in early trading Monday after the company resumed a proposed stock offering it had cancelled on Friday. Two Harbors Investment said it will resume a public offering of common stock, revising the number of shares to be offered to 11 million. On Friday, Two Harbors cancelled its proposed public offering of 14 million shares of common stock, having determined that the available share price "would result in an unacceptable dilution of book value to existing shareholders."
