Read the following paragraphs and answer the questions.
Procter & Gamble, the consumer products company, reached an agreement yesterday to acquire the Gillette Company1, the shaving-products and battery maker, for about $57 billion in stock, the companies said last night.
The merger, which is subject to approval by regulators, would create a consumer products powerhouse,2 combining some of the world's best-known brands like Procter's Tide, Crest and Pampers3 with Gillette's razors and blades, Right Guard deodorant and Duracell4. The combined company would have sales of more than $60 billion a year.
The agreement, which the boards of both companies approved late yesterday, will be announced today at a news conference in Midtown Manhattan5 , executives close to the deal6 said last night.
The friendly transaction reflects just how much the balance of power has shifted from consumer-products makers to giant discount retailers, mainly Wal-Mart, in recent years.
