A letter report issued by the Government Accountability Office with an abstract that begins "From 2008 through 2011, the Department of Health and Human Services' Food and Drug Administration (FDA) received 6,307 reports of health problems--adverse event reports (AER)--for dietary supplements; 71 percent came from industry as serious adverse events as required by law, and most of these AERs were linked with supplements containing a combination of ingredients, such as vitamins and minerals or were otherwise not classified within FDA's product categories. However, FDA may not be receiving information on all adverse events because consumers and others may not be voluntarily reporting these events to FDA, although they may be contacting poison centers about some of these events. From 2008 to 2010, these centers received over 1,000 more reports of adverse events linked to dietary supplements than did FDA for the same period. FDA officials said that they are interested in determining whether the poison center data could be useful for their analysis and have held discussions with American Association of Poison Control Centers representatives, but cost is a factor."

A letter report issued by the Government Accountability Office with an abstract that begins "Estimated tax revenue that the federal government forgoes resulting from corporate tax expenditures increased over the past few decades as did the total number of corporate tax expenditures. In 2011, the Department of the Treasury estimated 80 tax expenditures resulted in the government forgoing corporate tax revenue totaling more than $181 billion. Many of these tax expenditures are broadly available to both corporate and individual taxpayers. More than twothirds or 56 of the 80 tax expenditures used by corporations in 2011 were also used by individual taxpayers, such as other types of businesses not organized as corporations. Modifying any of these 56 tax expenditures as part of broader corporate tax reform would likely affect both corporate and individual taxpayers to some degree."
