Some of them are linked to the work we're doing on the human resource side. There are significant costs that are associated with staffing a position. With some of the streamlined processes that we've put in place for initiating staffing, particularly for jobs that are more common across the organization, we have a process that's allowing us to get those positions filled quicker, and in some cases it also allows us to reduce overtime costs associated with backfilling for that position that is vacant until it's staffed. And the tools that we've put in place on the human resource side are giving us much better information in terms of projecting where our needs are going to be and initiating our staffing processes well in advance, as opposed to waiting until the position becomes vacant.
So the initiatives under Mr. Macaulay's leadership in my human resources area are positioning us much better to have timely, effective, and cost-saving human resource measures in place.
