Tax-preparation firm H&R Block ( HRB) on Friday reduced its previously announced third-quarter earnings, after setting aside more money to pay for litigation settlements. The Kansas City, Mo.-based firm said it earned $12.1 million, or 4 cents a share, compared to $92.3 million, or 28 cents a share, a year ago. The tax firm reported preliminary earnings figures on Feb. 23, showing a profit of $28.8 million, or 9 cents a share, in the quarter ended Jan. 31. H&R Block said it decided to up its legal reserve by $11.9 million. The firm also incurred an additional $3.4 million in taxes in the third quarter, stemming from a restatement of its earnings for the past three years. The company also filed restated financial results dating back to 2003 on Friday. The restatement had been in the works for months. H&R Block previously had said it would be restating its prior-year earnings to correct a $32 million underreporting of its state income tax obligation. Last August, the firm said its auditor found a "material weakness'' in the firm's accounting for income taxes. Earlier this month, New York Attorney General Eliot Spitzer sued H&R Block, claiming it ripped off some of its customers by steering them into poor-performing IRA accounts.
