NEW YORK ( TheStreet) -- Here are 10 things you should know for Monday, Sept. 30: 1. -- U.S. stock futures were pointing to losses on Wall Street Monday as investors fear the U.S. government is headed for a shutdown. European stocks were falling early Monday. Asian shares ended the trading session lower. Japan's Nikkei 225 index declined 2.1%. 2. -- The economic calendar in the U.S. Monday includes the Chicago Purchasing Managers Index for September at 9:45 a.m. EDT. 3. -- U.S. stocks on Friday fell amid anxiety over the ongoing budget negotiations in Washington. The S&P 500 slumped 0.41% to 1,691.73. The Dow Jones Industrial Average shed 0.46% to close at 15,258.24. The Nasdaq declined 0.15% to finish at 3,781.59. 4. -- A GOP challenge to President Obama's health care law has the federal government teetering on the brink of a partial shutdown. The Senate has the next move on must-do legislation required to keep the government open past midnight on Monday, and the Democratic-led chamber is expected to reject the latest effort from House Republicans to use a normally routine measure to attack Obama's health care law. Congress was closed for the day on Sunday after a post-midnight vote in the GOP-run House to delay by a year key parts of the new health care law and repeal a tax on medical devices as the price for avoiding a shutdown. The Senate is slated to convene Monday afternoon just 10 hours before the shutdown deadline, and Majority Leader Harry Reid, D-Nev., has already promised that majority Democrats will kill the House's latest volley. The last government shutdown was 17 years ago. 5. -- Twitter is planning to make public its secret filing for an initial public offering as soon as this week, people familiar with the matter told The Wall Street Journal, meaning the shares of the social media company could begin trading by late October or early November if the offering moves quickly. News of the offering was first reported by Web site Quartz on Sunday. Twitter announced earlier in September via its own network that it had made a confidential filing with regulators. Under U.S. offering rules, the company can propose a price and launch its offering as soon as 21 days after it makes a public filing, according to the Journal. 6. -- Royal Dutch Shell ( RDS.A) said it plans to sell its 106,000-acre stake in the Eagle Ford Shale in South Texas, following a $2 billion write-down of North American assets that the oil company announced in August, the Journal reported. Shell told the newspaper the Eagle Ford holdings didn't meet the company's targets for size and profitability. The stake "offers a valuable growth opportunity for another experienced operator," Shell spokeswoman Kelly op de Weegh told the Journal. Shell will continue to operate its 150 production wells in the shale while allowing potential buyers to review technical data on the holdings. The possible value of the assets wasn't clear, according to the Journal. 7. -- Paychex ( PAYX), a provider of payroll and human resources benefits, is expected by analysts on Monday to post fiscal first-quarter earnings of 43 cents a share on revenue of $605.6 million.
