A rare provision in San Francisco’s business tax code that taxes companies when employees cash in their stock options has caused a stir in this hotbed of fledgling tech companies. Remarkably, few companies even knew about the tax, which has been in effect for seven years. But since city officials offered Twitter a payroll-tax break as an incentive for it to remain in San Francisco (the company is considered likely to go public soon), the stock-option provision has suddenly come under intense scrutiny. A number of other booming companies, including Zings, the maker of online games and one of the city’s fastest-growing firms, have threatened to leave the city unless they receive similar payroll-tax exemptions before going public.

Unlike most cities, San Francisco generates most of its business tax revenue through a payroll tax. The Twitter exemption bill, which will be considered by the full Board of Supervisors on April 5, would freeze payroll taxes for six years along a strip of Market Street—where Twitter is set to relocate—and several square blocks in the Tenderloin neighborhood. Twitter executives had been concerned because since 2004 the city’s payroll tax code has counted stock options granted to employees as compensation, which is taxed at 1.5 percent. If Twitter goes public in San Francisco and a large number of workers exercise their options, the city would tax the company on its employees’ stock gains—a bill likely to amount to tens of millions of dollars. "Twitter could be looking at a significantly larger payroll tax liability if and when it goes public," said Ted Egan, the chief economist in San Francisco’s controller’s office.

Because of the dearth of I. P. O. ’s inside the city limits in the last decade, the stockoption tax has gone under radar until now. Businesses, city officials and even seasoned tax lawyers are confounded. "Nobody ever talked about this because nobody’s really tested these issues before," said Thomas H. Steele, a partner in Morrison & Foerster’s San Francisco office, specializing in state and local tax. He said that his clients began calling him this week to ask about the tax’s ramifications. "A Pandora’s box has already been opened," said Supervisor Ross Mirkarimi, a member of the Board of Supervisors’ budget and finance committee, who has expressed concern about tailoring legislation for one company. "We’ve been going about this the wrong way," he said. The recent confusion has added impetus to calls for comprehensive business tax reform by David Chiu, the board president. "The stock option problem is real," Mr. Chiu said. "We have to address it in a fair and responsible way.

这儿还根本未考虑世上的书籍在不断地增多！不，每一个真正的读书家都能将现有的宝藏再研究苦读几十年或几百年，并为之欣悦不已，即使世界上不再增加任何一本书。我们每学会一种新的语言．都会增长新的体验——而世界上的语言何其多啊！……可就算一个读者不再学任何新的语言，甚至不再去接触他以前不知道的作品，他仍然可以将他的阅读无休止地进行下去，使之更精、更深。每一位思想家的每一部著作，每一位诗人的每一个诗篇，过一些年都会对读者呈现出新的、变化了的面貌，都将得到新的理解，在他心中唤起新的共鸣。我年轻时初次读歌德的《亲和力》，只是似懂非懂，现在我大约第五次重读它了，它完全成了另一本书！这类经验的神秘和伟大之处在于：我们越是懂得精细、深入和举一反三的阅读，就越能看出每一个思想和每一部作品的独特性、个性和局限性，看出它全部的美和魅力正是基于这种独特性和个性，——与此同时，我们却相信自己越来越清楚地看到，世界各民族的成千上万种声音都追求同一个目标，都以不同的名称呼唤着同一些神灵，怀着同一些梦想，忍受着同样的痛苦。在数千年来不计其数的语言和书籍交织成的斑斓锦缎中，在一些突然彻悟的瞬间，真正的读者会看见一个极其崇高的超现实的幻象，看见那由千百种矛盾的表情神奇地统一起来的人类的容颜。
