Deactivate lines

Q:  We would like to deactivate two lines at our home plant in M2 for the fourth quarter.  As far as we understand, deactivation occurs immediately when it is sent in with a decision.  Therefore, we did not deactivate the two lines on this decision.  However, the Player's Manual does not state this clearly - if we wait until the next decision (year 3, quarter 4) to choose to deactivate two lines, will they then be deactivated, and not a quarter later (year 4, quarter 1)?  We have enough cash in our budget to allow for this deactivation even in this decision, should it take one quarter to take effect.

Q:  Deactivation takes effect immediately.  If you don't need the lines for only a couple of quarters, you might find it less expensive to try "layoff" rather than deactivation.
