The two-year rollover works well for small investments. That was working fine there. When we're considering very large flagship investments that might be in the $1 billion to $4 billion range in manufacturing, the planning process before a board makes a decision to go ahead will take up to two years. It will then take almost two years to get regulatory approvals and for site preparation. It's only after anywhere from three years to four years, or four and a half years, before the machinery and equipment is brought onsite and is eligible for this reduction. Therefore, in the initial planning process where the board is trying to make a decision, they will not count this benefit in their calculations unless the measures are in place to that time period in the future when that machinery and equipment would be arriving. Therefore, it respects the business cycle and it also respects the ability to count on that measure being in place.
It was very important to go for a full business cycle.
