Good morning, everybody.
I just wanted to speak really briefly about the data products offered by NGX. All of our data products really are derived from transactional data. I think it's important to understand that we really are an exchange and clearing house, so our data products are all transactional based. For these discussions and the exploration to national data products, there are a couple of different types. There's the people looking to aggregate physical data, receive delivery data, storage information, and that type of thing. What NGX has really is the transactional piece.
As Steve mentioned, we have a very dominant market share. NGX calculates a couple of different key datasets or data products. We classify those as trading price indices or price indices, and then settlement curves. A price index is effectively just the weighted average of all the transactions in the applicable product. We calculate traded price, real-time price indices for natural gas, crude oil, and electricity, all just in Canada. While Steve did mention we clear about 60 or 70 locations in the United States as well, NGX has not published data products for those. We only publish Canadian data.
We also publish a lot of crude oil indices—again, Canadian only. These are transactions that are done on our brokerage arm, our sister company. Those transactions are then routed electronically to NGX, and we have an engine that we've developed internally to calculate the price indices as well. We do the same thing for electricity. We have electricity products here in Alberta and electricity products in Ontario as well that we clear.
Whenever we refer to a price index, it really is the weighted average of all the transactions done in the applicable instruments for that index.
A price settlement curve, which is also a very valuable piece of data to our client base, is really the projected pricing for any type of product or location of a product for that day. At the end of every day, NGX publishes approximately the forward 60 days and the 60 months. That's about two months of daily products and about five years of monthly products of pricing curves for every product that we clear. For every gas, electricity, and crude oil product across North America that we clear, we'll publish those price settlement curves once a day at the end of each day.
There are a couple of other ancillary products that we have. We do publish something called the Alberta market price as well, or the AMP. The Alberta market price is a product that we publish in tandem with the Department of Energy here in Alberta, so it really is a weighted average price of all gas that actually delivers. Regardless of trading time, it's all the gas that's delivered in a calendar month. That average is then used as part of the calculation for royalty payments by the Government of Alberta here too.
Each of those services that we mentioned has a different type of commercial structure. Many of them are proprietary and subscription-based so people have to subscribe in order to access those, but we do have some free data as well available on the NGX.com website. For example, for those settlement curves we talked about, we keep a rolling five-day list of them available for free on the NGX.com website. If a client wants to access our full history, and we have history going back in both price indices and settlement curves for about 20-some years. If you want to access that, that's a subscription cost. You have to pay for that, but if you're looking just to keep up to date on what the settlement prices are and what the curves are each day from a gas price perspective, you can access that for free on our website.
The AMP price we talked about that gets used in the calculation of the royalty price can also be accessed for free on the website. You can go there and check that out as well.
I think that's the crux of it. We just wanted to highlight the fact that we do offer data. It's transactional based. It's really across Canada. It's Canadian focused, and it is multi-commodity: electricity, crude oil, and natural gas.
