and subsidiaries. Subsidiaries are reported in Exhibit 21.1 of the 10-K form. I reviewed the most recent Exhibit 21.1 submissions to identify the
subsidiary companies of Alpha, Arch, Consol, and Patriot (available through the SEC’s EDGAR search tool accessible at http://www.sec.gov/edgar/searchedgar/companysearch.html). I cross-referenced the subsidiary lists with company production reports submitted to the OMHST (each company/subsidiary reports its total production each year). From that, I was able to calculate the total production of Alpha, Arch, Consol, and Patriot subsidiaries (based on the subsidiaries that they control), thereby giving me a more comprehensive sense of the production power that these four companies alone wielded in West Virginia in 2012.
