Segments

As discussed in Note 1, effective April 1, 2014, we changed the composition of our reportable segments. Prior-year results have been recast to conform with the new presentation of reportable segments. Our operations are organized into four reportable segments: Gypsum (previously North American Gypsum), Ceilings (previously Worldwide Ceilings), Distribution (previously Building Products Distribution) and UBBP. See Note 2 for segment results for UBBP. Segment results for our Gypsum, Distribution and Ceilings segments were as follows:

	Three months ended March 31,
(millions)	2015			2014 (b)
Net Sales:
Gypsum	$	577		$	545
