```sql

  pp.policy_period_eff_date AS EffectiveDate,
  NVL(pp.cancel_date, pp.policy_period_exp_date) AS ExpirationDate
FROM policy_period_all pp
JOIN (
  -- get the most recent issued period per policy
  SELECT
    pp.policy_num,
    MAX(pp.policy_period_eff_date) AS policy_period_eff_date
  FROM policy_period_all pp
  JOIN (
    -- get all issued periods for all policies
    SELECT
      policy_period_eff_date,
      policy_num
    FROM endorsement
    WHERE endorse_code = 'P401'

   AND pp.policy_period_eff_date = issued_periods.policy_period_eff_date
  WHERE pp.policy_period_eff_date <> NVL(cancel_date, policy_period_exp_date)
  GROUP BY pp.policy_num
) max_periods
  ON pp.policy_num = max_periods.policy_num
 AND pp.policy_period_eff_date = max_periods.policy_period_eff_date
WHERE pp.policy_num IN ({0})
