H&R Block Inc says that Compuserve Inc, in which it still holds 80%, expects to report an operating loss of $0.15 to $0.20 per share for its fiscal first quarter, ending July 31 because of flat subscriber growth within on-line services and continued investments in infrastructure improvements and the introduction of its Wow! service. The CompuServe Information Service lost over 1% of its subscribers during May and June and now has 3.4m. Block also said it would be spinning off its remaining interest in the company to its shareholders.
