UPDATE 1-Box shares fall as growth in paid customers slows

(Adds fourth-quarter details, share move)

Feb 28 (Reuters) - Cloud storage company Box Inc said on Wednesday it added 2,000 paid customers in the fourth quarter, fewer than its additions in the preceding quarter.

The company's shares fell 11 percent in extended trading.

Box, which competes with Dropbox Inc, Microsoft Corp's OneDrive and Google's Drive, had 82,000 paid customers at the end of the fourth quarter, up from 80,000 in the third quarter.

However, the rate of growth was slower compared with that in the third quarter, when it had signed on 4,000 new customers.

The company's net loss narrowed to $32.7 million, or 24 cents per share, in the quarter ended Jan. 31 from $36.9 million, or 28 cents per share, a year earlier.

On an adjusted basis, the loss was 6 cents per share. Analysts on average had expected a loss of 8 cents per share, according to Thomson Reuters I/B/E/S.

Redwood City, California-based Box said its revenue rose 24.3 percent to $136.7 million, in line with Wall Street estimates. (Reporting by Arjun Panchadar and Shariq Khan in Bengaluru; Editing by Maju Samuel)
