Lukoil is a Russian listed company available in the US as an ADR under the symbol LUKOY (as far as I can tell). When I search for it on Fidelity, I see this:
What does the "NK" mean in "NK LUKOIL PAO"? I guess "PAO" is transliteration of the Cyrillic "ПАО" which in turn stands for "public joint-stock company" (abbreviated PJSC). But I have no theory as to what the "NK" stands for. In general what is the name of this entire thing: "NK LUKOIL PAO"? It is not a ticker symbol. What is it then?
