NEW YORK--This time, don't blame the machines.

"Human error" at the Nasdaq Stock Market led to the postponement of an IPO from WhiteHorse Finance Inc. (WHF) on Wednesday, according to the exchange.

Nasdaq OMX Group Inc. (NDAQ) inadvertently halted the IPO rather than simply push back the timing Wednesday morning, according to people familiar with events at the exchange. The exchange works with underwriters, and often pushes listings back by a matter of minutes as an opening price is settled upon, but in this instance the IPO process was accidentally stopped, these people said. Shares in the rescheduled WhiteHorse IPO began trading later Wednesday afternoon.

A Nasdaq spokesman declined to offer details on the nature of the error, which was briefly described in a note to traders sent early Wednesday afternoon.

Shares fell in their belated late-afternoon debut, dropping $1.10, or 7.3%, to close at $13.90. Shares had been originally scheduled to begin trading at about 11 a.m. EST.

WhiteHorse, a business-development company that originates and invests in loans to small, private companies, priced its $100 million offering late Tuesday.

Alastair Merrick, WhiteHorse's chief financial officer, confirmed the trading problems Wednesday morning but didn't respond to requests for further comment this afternoon.

The troubled WhiteHorse debut comes after problems with high-profile listings earlier this year. Electronic exchange operator BATS Global Markets Inc. in March pulled its offering, carried out on its own exchange, after a software problem caused trading to be halted shortly after the debut. A month later, data company Splunk Inc. (SPLK) had some trades in its newly listed shares canceled due to a technical glitch on NYSE Euronext's (NYX) all-electronic Arca exchange.

Those episodes paled beside the fallout from Nasdaq's hugely anticipated Facebook Inc. (FB) IPO in May, when problems forming the opening trade in the stock left brokers and their customers unclear as to how many shares they held. The episode drove an estimated $500 million in losses for Wall Street firms, angered individual investors and prompted lawsuits against Nasdaq.

Unlike Wednesday's man-made troubles, those incidents were at least in part linked to technological issues.

"By itself [the WhiteHorse IPO] isn't a big deal," said Patrick Healy, head of Issuer Advisory Group, which helps companies choose an exchange for their listings. "But these mistakes are just becoming way too frequent, and they're killing investors' confidence."

Deutsche Bank AG (DB) J.P. Morgan Chase & Co. (JPM), Citigroup Inc. (C) and Barclays PLC (BARC.LN, BCS) served as the WhiteHorse IPO's prime underwriters.
