BARNES & NOBLE SAYS PIN PADS IN 63 STORES HACKED: NEW YORK (AP) — Barnes & Noble Inc. says devices customers use to swipe credit and debit cards have been tampered with in 63 of its stores in nine states.

The New York-based company is warning customers to check for unauthorized transactions and to change their personal identification numbers, or PINs. It hasn't said how many accounts may have been compromised.

The bookseller said in a statement Tuesday only one of the devices, known as PIN pads, was tampered with in each of the 63 stores. The stores are in California, Connecticut, Florida, Illinois, Massachusetts, New Jersey, New York, Pennsylvania and Rhode Island.

The company says it disconnected all the PIN pads in its nearly 700 stores nationwide on Sept. 14 after learning of the tampering.

NETFLIX SLASHES ITS FORECAST FOR SUBSCRIBER GAINS: LOS ANGELES (AP) — Netflix slashed its prediction for how many U.S. video-streaming subscribers it would add this year after subpar third-quarter results, causing a sharp sell-off in its stock in after-hours trading.

The Los Gatos, Calif.-based company said it added 1.2 million net streaming subscribers in the U.S. in the three months through September, which was on the low end of its forecast for gains between 1 million to 1.8 million.

The disappointing figure caused Netflix to cut its estimate for full-year U.S. streaming subscriber additions to between 4.7 million and 5.4 million. Previously, Netflix predicted it would gain as many as 7 million domestic streaming subscribers by year's end.

Growing streaming subscribers in the U.S. is crucial to Netflix because the number of DVD-by-mail subscribers continues to fall and its losses internationally are mounting. Last week, it added streaming service in Sweden, Denmark, Norway and Finland.

DOW CHEMICAL TO SLASH 2,400 JOBS, CLOSE 20 PLANTS: MIDLAND, Mich. (AP) — The Dow Chemical Co. will eliminate about 2,400 jobs and close roughly 20 manufacturing facilities as part of a restructuring plan aimed at coping with slowing economic growth in Europe and elsewhere.

The manufacturing giant said Tuesday that the job cuts amount to 5 percent of the company's workforce worldwide.

Dow expects the strategy will result in roughly $500 million in annual cost savings by the end of 2014.

The company also plans to slash capital spending and investments. It expects that will save an additional $500 million.

All told, Dow anticipates it will save $2.5 billion, including other cost-cutting measures.
