A profit by a business is written in black numbers. So a company that is "in the black" is making money. An international news service reported that a private health insurer in Australia announced it was "back in the black with its first profit in three years."企业利润都用黑色数字记录,所以,“in the black”代表企业处于盈利状态。一家国际新闻机构报道称,澳大利亚一家私人医疗保险公司宣布,三年来他们首次重新赢利。
