Dubai-based Islamic mortgage lender Tamweel posted its second-biggest profit ever in the second-quarter, beating analysts' forecasts as its home loan business more than doubled.

The UAE's second-largest mortgage financer by market value posted a 47.4 percent jump in second-quarter profit to 57.53 million dirhams ($15.67 million), compared with 38.94 million dirhams in the year-earlier period.

First-half net profit after depositors' share was 108 million dirhams, Tamweel said in a statement. Reuters calculated the second quarter based on previous financial data. The firm's first-quarter net profit was 50.47 million dirhams.

The results topped analysts' forecasts in a Reuters survey last month of between 49.33 million dirhams and 50.10 million dirhams.

Income from Islamic financing and investing assets in the second quarter more than doubled to 54.46 million dirhams, compared with 26.71 million dirhams in the year-earlier period, according to a Reuters calculation.

First-half income from Islamic finance and investing also about doubled 100.3 million dirhams, Tamweel said in a statement.

Assets, which include mortgages, rose 65 percent to 3.47 billion dirhams at June 30, Tamweel said.

Tamweel said in April it would allow foreigners to own as much as 40 percent of its shares, up from 21 percent, to broaden its investor base. Its shares fell 4.88 percent on Sunday before the results were released.

The firm said earlier this month it had started a real estate finance company in Saudi Arabia with a local partner. - Reuters
