Bank Muscat, Oman's largest lender, offered new shares to existing holders at a 25-percent discount to raise about $251 million to fund its credit growth and venture into Islamic finance.

Dubai Group, in the midst of a $10-billion debt restructuring, had the rights to buy an additional 33.387 million shares, valued at about 0.06 rials ($0.16).

The investment firm sold most of those rights at almost a 50-percent discount in two separate over-the-counter deals for between 0.03 rials and 0.035 rials each on Thursday, the sources said speaking on condition of anonymity.

"The rights sale is at a significant discount to the current value," said one market source. "It goes to show that the group has very little interest to commit additional capital in the bank and is trying to cash whatever value it can."

Dubai Group declined to comment. Bank Muscat did not respond to requests for comment.

Oman allows rights to be traded during the subscription period, enabling existing shareholders to pass on their rights to willing buyers. On Sunday, Bank Muscat shares were up 3.2 percent at 0.516 rials. The rights price stood at 0.073 rials.

Pricing on the rights is normally calculated as the difference between the rights issue price - 0.427 rials in Bank Muscat's offering - and the current market price. The bank's stock closed at 0.500 rials on Thursday.

Dubai Group bought its 14.7 percent stake in Bank Muscat for $619 million in 2007 through a private placement, making it the second-largest shareholder in the bank after Oman's Royal Court Affairs which represents the Omani ruler's personal interests.

The company has seen the value of that stake fall to around $400 million at current market prices.

DEBT WOES

Dubai Group, part of Dubai Holding DUBAH.UL, the personal investment firm of Sheikh Mohammed bin Rashid al-Maktoum, was hard hit by the global financial crisis and seen the value of most of its holdings deteriorate.

Like most other state-linked entities in the emirate, it embarked on negotiations with creditors to restructure debt and extend maturities.

Dubai Group is relying on asset sales to repay its obligations and wants time for values to recover before selling.

Its financial assets include stakes in Egypt's EFG Hermes (HRHO.CA), knocked by Middle Eastern turmoil, and Cyprus Popular Bank CPBC.CY, formerly Marfin, whose recapitalization forced Cyprus to seek an international bailout. Dubai Group also has a stake in Borse Dubai, which owns 20.6 percent of the London Stock Exchange.

In the latest blow to the firm's restructuring talks, Royal Bank of Scotland (RBS.L) and two other international banks abandoned talks and threatened to bring legal action against the investment vehicle, sources close to the matter told Reuters last week.

Bank Muscat's shares have dropped 10 percent since the rights sale kicked off on July 2, compared with a four-percent drop for the broader index over the same time. The shares are down 23 percent year-to-date. ($1 = 0.3851 Omani rials)
