Many states require companies to file “foreign registration” documents if they are an out-of-state entity incorporated elsewhere but doing business in their state. The Business Programs Division, the largest division of the Secretary of State's office, supports California Businesses by registering business entities and trademarks and enabling secured creditors to protect their financial interests. The Business Programs Division processes millions of business filings and information requests each year. The Secretary of State administers numerous other filings including immigration consultant and various business bonds, notices of joint powers, successor-in-interest, statement of facts – roster of public agencies, and athlete agents. With the acquisition of mills in Ashdown, Arkansas; Nekoosa and Port Edwards in Wisconsin; and Woodland, Maine, Domtar became Canada's largest paper company in terms of sales, third-largest producer of uncoated free sheet paper in North America, and fourth-largest in the world. The Port Edwards plant was closed in 2008 and sold in 2013, and the Woodland plant was sold in 2010. The Secretary of State's office processes filings, maintains records and provides information to the public relating to business entities that include corporations, limited liability companies, limited partnerships, general partnerships, limited liability partnerships and other business filings. The articles of incorporation are dominated with very general details of a corporation. They must state the legal name of the business, name a registered agent who can receive service of process and state the general purpose of the business.
