Currently we have no pipeline investigations ongoing. Last year we completed two pipeline investigations.
The way we proceed for pipelines is that because there are very few occurrences that we investigate, we allocate a notional amount that covers the salaries of two investigators who are dedicated to pipelines so that we have the capacity, the readiness. Then, in the year when we launch an investigation, we reallocate money between programs—i.e., from aviation or from marine to pipelines—to cover the cost of the investigations as the costs are incurred.
So that we don't have money that's sitting there unused, we reallocate and move money around, as required.
