Chairman James Wood also told stockholders A&P had an operating loss of $14.9 million in the first quarter ended May 24, in contrast with a profit of $3.4 million (14 cents a share) a year ago. Total net income in a year earlier was 19 cents a share with the help of a tax-loss carryover. Sales dropped to $1.64 billion in the latest quarter from $1.66 billion a year earlier.
