The acquisition will add to Walgreens' earnings beginning a full year after completion and will produce more than $1 billion in savings from cost overlaps, the companies said Tuesday in a <a hover="See Related Story" href="/document/NWWDP0MEQTXF" itemprop="StoryLink" itemscope="itemscope" link-type="news-stories" news-stories="NWWDP0MEQTXF" target="_blank" title="Walgreens Boots Alliance to Acquire Rite Aid for $17.2 Billion in All-Cash Transaction"><meta content="idm402992828" itemprop="ident">

<p>The company also reported fiscal fourth-quarter earnings showed how it reaps cost savings from mergers. Walgreens said it has saved $799 million in fiscal 2015 after combining with Alliance Boots GmbH last year.</p>

<meta content="RAD US Equity" itemprop="security">Rite Aid</a> shares fell 8.2 percent to $7.96 in early trading Wednesday, below Walgreens' offer of $9 a share, reflecting speculation that the transaction will face antitrust scrutiny. They had risen as high as $8.74 earlier after the Wall Street Journal reported the companies were close to a deal. Walgreens shares rose 1.4 percent to $96.50.</p>
<h3>Deal Opportunity</h3>
<p>Rite Aid's stock had slumped 29 percent since Sept. 16, after the company lowered profit and revenue forecasts for the year, giving Walgreens a potential opportunity to make an offer. The price represents a 48 percent premium to Rite Aid's closing price on Monday.</p>
<p>Speculation that Walgreens would pursue Rite Aid rose to a crescendo in March after <span bbg-href="bbg://screens/RICH" itemprop="StoryLink" itemscope="itemscope" title="Bloomberg Billionaires Index">billionaire<meta content="idm402968796" itemprop="ident">

<h3>Pharmacy Benefits</h3>
<p>In addition to expanding its drugstore locations, the Rite Aid deal gives Walgreens its first foray into the business of managing drug benefits for insurers and employers, an area where rival CVS is a leader. Rite Aid entered that business by acquiring Envision Pharmaceutical Services Inc. for about $2 billion this year.</p>
<p>If Walgreens aims to get bigger in drug-benefit management, it could use EnvisionRX to acquire other small competitors to build that business, said <a hover="Person Profile" href="javascript:void(0);" itemprop="StoryLink" itemscope="itemscope" link-type="person" person="7366934" title="Person Profile" class="hoverDocumentLink" id="person_7366934"><meta content="idm402962036" itemprop="ident">

<meta content="true" itemprop="active">
<meta content="StoryLink" itemprop="type">
<meta content="NWXGN36K50XY" itemprop="suid">reported fiscal fourth-quarter earnings</a> that beat analysts' estimates. Excluding one-time items, earnings were 88 cents a share, beating the 81-cent average of analysts' estimates compiled by Bloomberg. Walgreens' pharmacies filled 222 million prescriptions in the quarter, up 4.6 percent from a year before.</p>
<h3>CVS's Moves</h3>
<p>While Pessina had made clear his appetite for deals, he had been cagey about what kind of acquisition he might pursue. He has said only that the company wanted to participate in what he saw as the inevitable consolidation of the long distribution chain that delivers drugs from manufacturers to patients in the U.S.</p>
<p>While Pessina prowled for a deal, CVS stayed busy. In May, Walgreens' top rival agreed to purchase nursing-home pharmacy Omnicare Inc. for $12.7 billion, expanding services to the country's elderly. Less than four weeks later, CVS struck a deal to acquire Target Corp.'s pharmacies and clinics for $1.9 billion, putting its brand, which includes OneMinute Clinics, in retail locations across 47 states.</p>
<p>"Their biggest competitor in the U.S. has been getting bigger," said <a hover="Person Profile" href="javascript:void(0);" itemprop="StoryLink" itemscope="itemscope" link-type="person" person="16849787" title="Person Profile" class="hoverDocumentLink" id="person_16849787"><meta content="idm403136676" itemprop="ident">

<p>Walgreens already has a foothold in the drug-distribution business after it signed a 10-year agreement with AmerisourceBergen in 2013 and became the company's third-largest shareholder.</p>
<p>Today's Walgreens was built by acquisition. Pessina developed Bern, Switzerland-based Alliance Boots into a powerhouse through more than three decades of mergers before selling it to Walgreen Co. last year. He's now the company's largest shareholder with a 13 percent stake.</p>
<p>Walgreens will revamp Rite Aid's stores to focus on health, wellness and beauty, just as it has been remaking its own stores since the Alliance Boots deal, the company said. Rite Aid will continue to operate under its own brand at first, though eventually the plan is to integrate the two chains.</p>
<p>The acquirer plans to finance the deal with cash and new debt, it said. UBS AG was Walgreens' financial adviser, with Simpson Thacher & Bartlett LP and Weil, Gotshal & Manges LLP providing legal advice. Citigroup Inc. gave financial advice to Rite Aid, with legal counsel from Skadden, Arps, Slate, Meagher & Flom LLP and Jones Day.</p></section><section class="news-footer"><p>--With assistance from <span itemscope="itemscope" itemtype="http://schema.org/Person"><link href="http://bloomberg.com/StoryFormat/ContactInfo" itemprop="additionalType">

如何在JavaScript中仅删除以<section class="news-rsf-abstract"></section>开头的部分。
答案 0 :(得分：3)
<section class="x123"></section>
<section class="x456"></section>
<section class="y789"></section>
要按类“x”开头删除section元素：
$('section[class^="x"]').remove();
答案 1 :(得分：-1)
如果它是唯一具有该类名的人，那么这将起作用：
$("section[class='news-rsf-abstract']").remove();
如果没有，但它始终是第一个标签，这将有效：
$('#chunk_content').find('section').first().remove();
如果这些都不属实，则需要其他标准以确保定位正确的section元素。
