Mandatory Price Reporting (MPR) data indicates that for barrows and gilts purchased in 2011 on a carcass weight basis by non-small packers, 4.2% were negotiated purchases, 38.4% were market formula contracts (formula priced from reported hog or pork prices), 9.8% were priced off of the futures market, 15.2% were other types of contracts, 4.7% were purchased from another packer, and 27.6% were raised by the packer that slaughtered them. Over the 10 year history of MPR, the biggest change has been in the number of negotiated purchases (down 10.4 percentage points) and packer owned (up 10.2 percentage points). Negotiated sales may not be a viable pricing method much longer. They have declined at slightly over one percentage point per year for the last decade.
