Strategic business planning is required for the successful transfer of control between generations in family-owned companies. However, a survey of 264 privately held family firms whose annual turnover exceeded one million dollars it was found that 114 had no strategic business plan.

Give the lower limit only and report your answer correct to three decimal places.
