When Liam McGee departed as president of Bank of America in August, his explanation was surprisingly straight up. Rather than cloaking his exit in the usual vague excuses, he came right out and said he was leaving "to pursue my goal of running a company. " Broadcasting his ambition was "very much my decision," McGee says. Within two weeks, he was talking for the first time with the board of Hartford Financial Services Group, which named him CEO and chairman on September 29.
McGee says leaving without a position lined up gave him time to reflect on what kind of company he wanted to run. It also sent a clear message to the outside world about his aspirations. And McGee isn’t alone. In recent weeks the No. 2 executives at Avon and American Express quit with the explanation that they were looking for a CEO post. As boards scrutinize succession plans in response to shareholder pressure, executives who don’t get the nod also may wish to move on. A turbulent business environment also has senior managers cautious of letting vague pronouncements cloud their reputations.
As the first signs of recovery begin to take hold, deputy chiefs may be more willing to make the jump without a net. In the third quarter, CEO turnover was down 23% from a year ago as nervous boards stuck with the leaders they had, according to Liberum Research. As the economy picks up, opportunities will abound for aspiring leaders.
The decision to quit a senior position to look for a better one is unconventional. For years executives and headhunters have adhered to the rule that the most attractive CEO candidates are the ones who must be poached. Says Kom/Ferry senior partner Dennis Carey: "I can’t think of a single search I’ve done where a board has not instructed me to look at sitting CEOs first. "
Those who jumped without a job haven’t always landed in top positions quickly. Ellen Marram quit as chief of Tropicana a decade age, saying she wanted to be a CEO. It was a year before she became head of a tiny Internet-based commodities exchange. Robert Willumstad left Cifigroup in 2005 with ambitions to be a CEO. He finally took that post at a major financial institution three years later.
Many recruiters say the old disgrace is fading for top performers. The financial crisis has made it more acceptable to be between jobs or to leave a bad one. "The traditional rule was it’s safer to stay where you are, but that’s been fundamentally inverted," says one headhunter. "The people who’ve been hurt the worst are those who’ve stayed too long. \

中国H公司同德国S公司在上海签订了一份货物买卖合同，约定合同履行中若发生争议，则双方应当在德国L州法院诉讼解决。H公司依据合同交付了货物，但S公司迟迟未将货款汇入合同约定的帐户，于是H公司起诉至北京市中级人民法院，请求法院判决S公司履行合同并赔偿相应的损失。S公司在收到起诉状副本后，并未就管辖权提出异议，并且在规定的时间内提交了书面答辩状。北京市中级人民法院经审理后，判决德国S公司败诉。德国S公司于是以合同中约定管辖法院为德国L州法院、北京市中级人民法院无权管辖该案件为由，上诉至北京市高级人民法院。则对于该案件，下列判断中正确的是（）

A．因为合同双方在合同中约定了管辖法院，所以北京市中级人民法院无权管辖该案件，北京市高级人民法院应当裁定撤销一审判决并终结诉讼

B．虽然合同双方约定了管辖法院，但是因为该约定违反了我国民事诉讼法对管辖的规定，因此是无效的

C．虽然合同双方约定了管辖法院，但是因为S公司并未对管辖权提出异议且提交了书面答辩状，因此应当视为承认了北京市中级人民法院对本案的管辖权，因此北京市高级人民法院应当驳回其上诉，维持原判

D．虽然合同双方约定了争议在德国L州法院诉讼解决，但是因为L州法院同合同之间没有关系，因此该约定是无效的
