Higher selling prices and greater unit volumes...

Higher selling prices and greater unit volumes contributed to Cincinnati-based Procter & Gamble’s 15% rise in worldwide net sales and a 12% increase in profit for the six-month period and gains in revenue and earnings for the second quarter. Growth in net earnings and earnings per share, however, was adversely affected by a higher effective tax rate due to the absence of U.S. investment tax credits in the October to December 1986 quarter, the firm said.
