      <Desc>The Foundation is at the forefront of pediatric surgical care, specializing in nine surgical disciplines and a number of multidisciplinary programs. The Foundation has a reputation for the finest quality care, superb teaching, and ground-breaking research. The latest advances in surgical treatments and state-of-the-art technology, coupled with a spirit of compassion and more years of experience than any other pediatric surgical group in the Midwest creates the vital difference to our patients and their families: Cardiovascular-Thoracic Surgery; Neurosurgery; Ophthalmology; Orthopedic Surgery; Otolaryngology; Pediatric Surgery; Plastic Surgery; Transplant Surgery; Urology.In addition, 35-45% of the patients served by the Foundation are covered by Medicaid. The shortfall of the reimbursement versus the actual surgical costs are absorbed by the Foundation as a benefit to the community.</Desc>

        <ExplanationTxt>The Foundation adopted the accounting standard on accounting for uncertainty in income taxes, which addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under this guidance, the Foundation may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. Examples of tax positions include the tax-exempt status of the Foundation and various positions related to the potential sources of unrelated business taxable income. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement. The guidance on accounting for uncertainty in income taxes also addresses de-recognition, classification, interest and penalties on income taxes, and accounting in interim periods. At August 31, 2016 and 2015, there were no unrecognized tax benefits identified or recorded as liabilities. The Foundation files Forms 990 in the U.S. federal jurisdiction and the State of Illinois. With few exceptions, the Foundation is no longer subject to examination by the Internal Revenue Service for years before August 31, 2013.</ExplanationTxt>
