        <FormAndLineReferenceDesc>Schedule C, Part III-B Lobbying Activities</FormAndLineReferenceDesc>
        <ExplanationTxt>To stay on top of federal issues that affect dentistry and the public's oral health, the ADA maintains a staff of legislative and policy experts close to Capitol Hill. Proximity, experience and representation of the vast majority of dentists make the ADA uniquely effective in lobbying for the dental profession. Many other critical issues are decided by legislators and regulators at the state level. Although the ADA does not lobby at the state level, we do provide expertise and resources to help state dental societies create and effectively pursue their own policy agendas. At both the federal and state levels of government, we constantly monitor legislation and, when appropriate, engage in the debate, fighting for laws and regulations that matter to dentists and the patients they serve.</ExplanationTxt>

        <ExplanationTxt>Deferred taxes are established for temporary differences between the financial reporting basis and the tax basis of assets and liabilities. Deferred taxes are based upon enacted tax rates, which would apply during the period in which taxes become payable or recoverable, and the adjustment of cumulative deferred taxes for any changes in the tax rate. The Association accounts for uncertain tax positions in accordance with ASC Topic 740, Income Taxes. ASC Topic 740 addresses the determination of how tax benefits claimed or expected to be claimed on a tax return should be recorded in the consolidated financial statements. Under ASC Topic 740, the Association must 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 the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. ASC Topic 740 also provides guidance on derecognition, classification, interest, and penalties on income taxes and accounting in interim periods and requires increased disclosures. As of December 31, 2017, there was no liability related to uncertain tax positions for federal and state income taxes.</ExplanationTxt>
