In this annual report on Form 10-K, "USG," "we," "our" and "us" refer to USG
Corporation, a Delaware corporation, and its subsidiaries included in the
consolidated financial statements, except as otherwise indicated or as the
context otherwise requires.
USG, through its subsidiaries, is a leading manufacturer and distributor of
building materials. We produce a wide range of products for use in new
residential, new nonresidential, and residential and nonresidential repair and
remodel construction as well as products used in certain industrial processes.
Our businesses are cyclical in nature and sensitive to changes in general
economic conditions, including, in particular, conditions in the North American
housing and construction-based markets, which are our most significant markets.
For the new residential construction market, housing starts are a very good
indicator of demand for our gypsum products.
