Minneapolis-based Computer Network Technology Corp, last resting place of the super-high-speed UltaNet following its acquisition last year of the company that developed it, is finding that the product is a disappointingly difficult sell: it plans to go on marketing it and supporting customers, but it is taking a pre-tax charge against earnings that will translate to a net $2.8m or seven cents a share for the write-down of excess inventory associated with the UltraNet product line; it took the charge partly because some current and potential customers indicated that they did not plan to place any future orders for UltraNet products.
