Nasdaq OMX Group Inc. (Nasdaq: NDAQ) will change its initial public offering trading procedures as a result of glitches and delays which occurred during Friday's Facebook Inc. (Nasdaq: FB) IPO, mistakes for which the exchange operator hopes to pay $13 million to burned investors, sources reported Monday.

The exchange said it would modify its IPO procedures to prevent a repeat of the problems which occurred on Friday, according to Reuters. Facebook's IPO was delayed by more than 40 minutes due to a malfunction in the exchange's order-cancellation system.

Facebook was the first U.S. company to have an IPO worth more than $100 billion.

The U.S.Securities and Exchange Commission is investigating the failure. Nasdaq approached federal regulators to help sort out Friday's problems, according to Reuters. The issues with the Facebook IPO could eventually lead to restitution for investors whose orders were not filled at the desired price.

The Nasdaq's rules cap total payouts at $3 million, but the exchange is seeking approval to add an additional $10 million in proceeds from its own 5,000-share position in Facebook gained as a result of intervening to fix the IPO process, according to the Wall Street Journal. Approximately 30 million shares were affected during the pre-IPO period on Friday and total losses across all firms may reach $100 million.

In many cases, brokers and traders didn't learn of the results of trades entered on behalf of institutions and retail investors for hours, and the results weren't what had been planned, the Wall Street Journal reported. Nasdaq attempted an after-hours auction on Friday to make investors whole, but it didn't produce results.

The Financial Industry Regulatory Authority (Finra) will review requests by investors to review orders which weren't filled at the initial price of $42 or were filled at a lower price, according to Reuters.

Facebook Inc. (Nasdaq: FB) shares fell 10 percent or $3.83 to $34.40 in late Monday trading. The company opened at $42.02 on Friday. Nasdaq OMX Group Inc. (Nasdaq: NDAQ) rose 3.77 percent to $22.82 in late Monday activity.
