International companies trading in New York closed lower Thursday amid concerns about what stronger-than-expected U.S. growth could mean for Federal Reserve policy.

The Bank of New York index of ADRs fell 1.7% to 146.26.

Better-than-expected U.S. third-quarter gross domestic product figures added to concerns that the Fed might begin scaling back its $85 billion-a-month asset purchases sooner than expected.

Meanwhile, the European Central Bank cut its benchmark interest rate to 0.25% from 0.5%.

The European index dropped 1.6% to 142.13.

Italy's Telecom Italia SpA (TI, TIA, TIT.MI) said its third-quarter net profit fell more than 27% compared with the same period last year, while it posted a net loss of 902 million euros ($1.2 billion) because of a previously announced write-down of around EUR2.2 billion. The company also said the board approved a mandatory convertible bond of a maximum EUR1.3 billion due November 2016. Shares fell 5.1% to $9.48.

However, ArcelorMittal SA (MT, MT.FR, MT.AE), the world's largest steelmaker, narrowed its loss in the third quarter and said it was "cautiously optimistic" about prospects for 2014 as steel demand picks up in China, the U.S. and even Europe. Shares of the Luxembourg-based company rose 2.5% to $16.59.

West Africa gold producer Randgold Resources Ltd. (GOLD, RRS.LN) reported a drop in third-quarter profit despite increased production, as lower gold prices hit earnings. But the bottom line still beat expectations. Shares of the U.K.-based gold miner rose 4% to $77.24.

The Asian index tumbled 1.9% to 146.03.

The New York Stock Exchange said Thursday that Suntech Power Holdings Co.'s (STP, K3ND.SG) shares will be delisted before the start of trading Monday. The reason for the delisting is "uncertainty" over whether Suntech can complete its 2012 annual report on time "in light of the ongoing restructuring involving the company." A Suntech spokesman declined to comment on the delisting to The Wall Street Journal. Shares fell 30% to 88 cents.

Meanwhile, fellow Chinese solar company, China Sunergy Co. (CSUN) said while there were many positive takeaways in the second quarter, Chinese banks "significantly tightened credit facilities to solar companies, which caused us to face a constrained working capital and reduced our ability to procure adequate inventory for subsequent production." As such, the company said it expects lower shipment volume and profitability for the third quarter of 2013 and expects lower total shipment for the full year 2013. Shares fell 24% to $7.17.

The Latin American index fell 2.3% to 291.28 and the emerging markets index shed 1.9% to 275.15.

Brazilian mining giant Vale SA's (VALE, VALE3.BR, VALE5.BR) net profit more than doubled in the third quarter on the back of strong iron-ore production and rebounding prices, a positive sign from the mining world's third-biggest player by market capital and revenue, after some two years of declining results. However, shares fell 5.2% to $16.18 amid investor concerns that China may tighten credit after a once-in-a-decade meeting of Chinese leaders this weekend.
