That's a mouthful called adjusted earnings before interest, tax, depreciation and amortisation ( ebitda), and the total there between 2013 and 2015 came in at a positive$ 1.7bn.

那是一个极其绕口的词：息税折旧及摊销前利润（Ebitda），2013年至2015年期间该数据的总额为17亿美元。

This expands the pool of potential hires, but keeps these new staffers from draining the expensive time of senior people on their first projects with questions about what EBITDA means and how to line up numbers on Excel.

此外，新员工们参与第一个项目时，也不会因为不懂息税折旧摊销前利润（EBITDA）是什么意思，怎么在Excel中排列数字这些问题来浪费老员工们的宝贵时间。

That kind of valuation brings with it breathtaking multiples: 53.2 times ( March) 2014 year end GAAP earnings, 40 times EBITDA, and 23.4 times revenues.

相应的估值倍数很是惊人：是按美国通用会计准则计算的截至2014年（3月）的年度收益的53.2倍，息税折旧摊销前利润的40倍，以及营收的23.4倍。

Even though Zynga missed quarterly earnings numbers in its first two quarters as a public company and slashed its 2012 EBITDA outlook in half, the company is still making money.

尽管这家上市公司今年头两个财季的季度营收未能达标，还把2012年预期息税折旧摊销前利润（EBITDA）削减了一半，但公司仍在赚钱。

But now the ebitda multiples paid by private equity shops are sometimes higher than the price/ earnings multiples at which sensible, publicly listed companies trade.

但如今，私人股本公司支付的ebitda倍数有时高于合理公开上市公司的市盈率（PE）。

This is the highest ratio since 2007, when the average debt portion reached a peak of 6 times ebitda, and surpasses the 2006 level of 5.1 times.

这是自2007年来的最高比例&2007年并购债务资金规模平均达到ebitda6倍的峰值，超过了2006年的5.1倍水平。
