New accounting rules, rising medical costs and extended life spans threaten to further balloon its long-term care insurance headaches, and GE is still awaiting the outcome of a Justice Department investigation into its legacy subprime mortgage business. Other unknowns include a bigger-than-expected bill from the U.S. tax overhaul; a large, unfunded pension balance; and a shareholder lawsuit alleging both financial mismanagement of the legacy long-term care business as well as accounting fraud related to the way it recorded revenue and earnings for product service agreements (GE denies these accusations). Until Culp puts a credible handicap on the company's overall liabilities, investors will struggle to get comfortable with the valuation math. Culp then has to find the cash to make good on all these obligations.
