Shortened Benefit Period = A non-forfeiture option that reduces the benefit period but retains the full daily maximums applicable until death.  The period of time for which benefits are paid will be shorter.

For example, you buy a policy for three years of coverage with a $150 daily benefit, but if you let the policy lapse, the benefit period is reduced to one year, with full daily benefits paid.  The exact amount of the reduction depends upon how much premium you have paid on the policy.  Unlike extended term benefits, which must be used in a certain amount of time after the lapse, you can use shortened benefits at any time after you let the premium lapse (until death).
