It is our new policy that any page containing timely information must clearly identify the date when that page was posted or updated. In addition, over the next few months as we completely overhaul all our data, we will make mention of each data category, latest update and frequency of these updates here.
*Sources: As a company committed to securing the most comprehensive data available, we must be constantly securing and negotiating data content relationships. Because we feel we would lose the competitive advantage by making public our sources of data, we guard it tightly. However, depending on the request, we would be glad to discuss these sources under an executed NDA (Non disclosure Agreement). We trust you understand.
