    including control of cases, the “occurrence” date, expenses,       approach four) as the rationale for reaching that result.
    St. Paul was incorrectly forced to expend or absorb costs related to
    the renewal agreement, and premiums. St. Paul insisted upon        defense, but both parties were equally responsible for the failure of the
    higher premiums, higher deductibles or cost sharing, or a          double-auditing system to catch the problem. This was not a situation
    combination of these. Several policy proposals were                where the insurer had sole access to relevant records or where the insurer
    discussed, including one for a combined defense-and-               was conducting the only auditing. It was not until February 1996 that

    that the insurer was not fulfilling its duty to defend.” Since both prongs
    under approach four must be satisfied, the date of accrual will always be
    pushed back to the date when the latter of the two prongs has been
    satisfied. In this case, prong two of approach four produces the same
    accrual date as approach two.

    date of accrual. The trial court judge calculates the                 Lincoln Electric’s view is that St. Paul knew it could not avoid the
    amount of prejudgment interest. If a favorable                  occurrence coverage it had already sold, nor prevent future claims from

    Lincoln Electric informed St. Paul that it believed the pre-                    allocation of deductibles, legal costs, and legal

    A “continuing injury” trigger applies those policies in effect at any

    there was no ambiguity.13 As a consequence, this court must
    scrutinize most of the district court’s disposition of this case

    extent that material facts for this case must be derived from
    findings of the district court, we rely upon those findings of
    fact because we are unable to say that the court committed
    clear error. Aside from the errors specifically identified in
