????德國(guó)最大的電信公司德國(guó)電信于1996年赴美上市，通過IPO籌集了130億美元。這是本榜單上歷史最悠久的IPO。該公司于2010年從紐約證券交易所退市，因其希望減少報(bào)告義務(wù)和行政成本。

????不過，在美國(guó)資本市場(chǎng)上仍能看到該公司的影子。德國(guó)電信旗下子公司T-Mobile US后來通過與MetroPCS公司合并，于2012年10月實(shí)現(xiàn)借殼上市。

????7. AT&T 無線集團(tuán)：106億美元

????Deutsche Telekom, Germany's largest phone company, raised $13 billion when it went public in the U.S. market in 1996. It is the oldest IPO to make the list. The company delisted from the NYSE in 2010 after saying it wanted to reduce its reporting obligations and administrative costs.

????However, vestiges of the company remain on the U.S. market. The company's subsidiary, T-Mobile US TMUS -1.13% , later went public by combining with MetroPCS in a reverse merger in October 2012.

????7. AT&T Wireless Group: $10.6 billion

????AT&T 無線集團(tuán)于2000年通過IPO融資106億美元。這家公司的結(jié)構(gòu)隨后發(fā)生變化。當(dāng)時(shí)，該公司是美國(guó)標(biāo)志性電信企業(yè)AT&T Corp旗下子公司，后來重組更名為Cingular Wireless，但其資產(chǎn)最終又重新注入母公司。到2005年，該公司再次重組改名，成為“新”AT&T。此后，該公司的資產(chǎn)結(jié)構(gòu)至今仍基本保持不變，并沿用其歷史交易代碼：T。

??AT&T exists today in a form much different form than the AT&T Wireless Group that went public in 2000 to the tune of $10.6 billion. Back then, it was the wireless subsidiary of AT&T Corp., which eventually transformed into Cingular Wireless before wrapping back into its iconic telephone-company parent. The company dubbed the company's latest iteration the "new" AT&T in 2005. That version of the company still exists pretty much intact today and trades under its historic ticker symbol: T.
