LandAmerica Financial Group Inc., primarily a title insurer, said Tuesday it plans to cut 1,100 jobs in the second-half of 2007 because of a slowdown of the mortgage origination market.

The cuts would slash the company’s payroll by 13 percent from its June 30 level. LandAmerica has already eliminated 1,000 positions since the start of the year, including 300 since July 1.
