According to State, the OAS is the primary inter-American political forum through which the United States engages with other countries in the Western Hemisphere to promote democracy, human rights, security, and development. While PAHO, IICA, and PAIGH are independent organizations, the Charter of the Organization of American States (OAS Charter) directs them to take into account the recommendations of the OAS General Assembly and Councils. PAHO, a specialized international health agency for the Americas, works with member countries throughout the region to improve and protect people's health and serves as the Regional Office for the Americas of the World Health Organization, the United Nations agency on health. IICA, among other things, supports its member states' efforts to achieve agricultural development and rural well- being through consultation and the administration of agricultural projects through agreements with the OAS and other entities. PAIGH specializes in regional cartography, geography, history, and geophysics and has facilitated the settlement of regional border disputes. Member states collectively finance these organizations by providing assessed contributions, in accordance with the organizations' regulations. The member states' assessed contributions are intended to finance the organizations' regular budgets, which generally cover the organizations' day-to-day operating expenses, such as facilities and salaries. Member states of each organization meet to review and approve the organizations' budgets. The exact dollar amount each member state is responsible for providing corresponds to its assessed percentage of the total approved assessment for any given year. The budgets are based on total approved quota assessment and other projected income. The OAS's system for determining member states' quotas is used to calculate member states' assessed contributions by the other three organizations. Thus, any change in the OAS's assessed quota structure should be reflected at PAHO, IICA, and PAIGH, according to their respective processes regarding the determination of assessed contributions. Member states also finance certain OAS, PAHO, and IICA activities through voluntary contributions. Member states generally target these contributions toward specific programs or issue areas. According to U.S. officials, the United States provides voluntary contributions to the OAS, IICA, and PAHO primarily through grants for specific projects from State, the U.S. Agency for International Development, the U.S. Department of Agriculture, and the Department of Health and Human Services. For example, according to OAS documentation, in 2015, State contributed slightly more than $200,000 to the OAS to fund judicial training to combat money laundering. According to U.S. agency officials, the organizations' regional knowledge and technical expertise make them effective implementing partners for projects serving U.S. national interests and priorities throughout the hemisphere. The Reform Act directs the Secretary of State to submit "a multiyear strategy that...identifies a path toward the adoption of necessary reforms that would lead to an assessed fee structure in which no member state would pay more than 50 percent of the OAS's assessed yearly fees." According to the Reform Act, it is the sense of Congress that it is in the interest of the United States, OAS member states, and a modernized OAS that the OAS move toward an assessed quota structure that (1) assures the financial sustainability of the organization and (2) establishes, by October 2018, that no member state pays more than 50 percent of the organization's assessed contributions. The United States' assessed contributions constituted over 57 percent of total assessed contributions by member states to the OAS, PAHO, IICA, and PAIGH from 2014 through 2016, as shown in table 1. During this time, the United States' assessed quota for these organizations did not change, and the total assessed contributions for all member states of these organizations remained about the same; thus, the actual amounts assessed to the United States generally remained the same. All four organizations apply a similar assessed quota structure that uses the relative size of member states' economies, among other things, to help determine each member state's assessed contributions. The OAS determines the assessed quota for each member state based on the United Nations' methodology, as adapted for the OAS, using criteria that include gross national income, debt burden, and per capita income. In addition, the OAS applies a minimum assessed quota of 0.022 percent and a maximum assessed quota of 59.470 percent. According to State officials, the OAS last made a major revision to its assessed quota structure in 1990 when Canada joined the organization, and the United States' and other members' assessed quotas were reduced as a result. OAS officials said that while member states seek, as far as possible, to adjust the assessed quota structure through consensus, the OAS General Assembly may force a vote and adopt changes with a two-thirds majority. The United States also provided voluntary contributions totaling about $105 million to the OAS, PAHO, and IICA from calendar years 2014 through 2016, as shown in table 2. In 2014, the United States contributed $37 million in voluntary contributions, or approximately 22 percent of the total of $168 million in such contributions from all member states. In 2015, the United States contributed $36 million, or approximately 29 percent of the total of $123 million from all member states. In 2016, the United States contributed $32 million, or approximately 22 percent of the total of $143 million from all member states. According to U.S. officials, levels of U.S. voluntary contributions vary year-to-year due to factors that include the schedule of multiyear grant disbursements, member states' priorities, and sudden crises. For example, the U.S. Agency for International Development made a $200,000 contribution to PAHO in 2016 for post- earthquake reconstruction and resilience-building in Ecuador. State is working with other member states toward reforming the OAS's quota structure for assessed contributions so that no member state provides more than 50 percent of the organization's annual assessed contributions, but State officials told us that reaching consensus among OAS member states will be difficult. In response to the Reform Act, State developed a strategy that identified a path toward the adoption of necessary reforms that would lead to an assessed quota structure in which no member state would pay more than 50 percent of the OAS's annual assessed contributions. State officials told us that they submitted the strategy to Congress in April 2014. The strategy included efforts to engage member state governments to explore options for reforming the quota structure and to examine the extent to which the OAS's quota- setting methodology reflects member states' capacity to finance the organization's activities. According to the OAS and State's 2015 report to Congress, achieving quota structure reform will require one or more of the other major contributors to accept an increase in their quotas--the percentages of total annual assessed contributions that they agree to provide. State officials told us that they have been working to implement this strategy. For example, State officials told us they engaged with other OAS member states, including Canada and Mexico, to explore options for quota structure reform. According to State officials, Canada led a modernization committee that produced a strategic plan that included quota structure reform. State officials added that they also reached out to member states from the Caribbean to discuss the importance of quota structure reform while highlighting OAS development programs that benefit Caribbean nations. In addition, officials at the U.S. Mission to the OAS worked with their counterparts from Mexico to review the OAS's assessed quota structure and to consult on alternatives that would adjust all member states' quotas so that no member pays more than 50 percent of the OAS's assessed contributions. According to State officials, the four largest contributing member states, including the United States, have agreed on the importance of quota structure reform. State officials added that quota structure reform efforts were bolstered by the selection of a reform-minded OAS Secretary General in 2015. However, State officials told us that while it will be difficult, it is not impossible for OAS member states to reach consensus on reforming the organization's assessed quota structure by October of 2018. Several issues among the member states have impeded the progress of State's strategy, according to State and OAS officials. These issues include the following: State and OAS officials told us that regional political tensions have complicated OAS member states' ability to reach consensus on quota structure reform. According to State officials, Venezuela's contentious political relationship with the OAS has hindered progress on various efforts promoted by the United States, including quota structure reform. State officials added that Venezuela has actively worked against the OAS to undermine the normal procedures of the organization. State officials told us that some member states have at times supported Venezuela during committee votes. For example, according to State officials, some member states voted against bringing proceedings against Venezuela for violating the Inter- American Democratic Charter in 2016. In this context, State officials emphasized that it was important for member states other than the United States to officially propose resolutions on quota structure reform. State officials told us that certain member states' nonpayment of their assessed contributions also has impeded the quota structure reform effort, as well as contributing to financial difficulties at the OAS. Venezuela has expressed publically its unwillingness to pay its assessed contributions, according to State officials. Additionally, as of November 2016, the OAS projected that five member states would be more than $17 million in arrears on their assessed contributions to the OAS by the end of 2016. Brazil--the OAS's second largest contributor--and Venezuela had not fully paid their assessed contributions for 2015 and 2016, which accounted for approximately 99 percent of the more than $17 million in arrears that member states owed the OAS. State officials told us that the large amounts owed by a few member states had contributed to smaller OAS member states' reluctance to increase their annual assessed quotas to ensure that no member state provides more than 50 percent by 2018. According to State officials, the United States repeatedly urged the Brazilian government to pay its arrears and 2016 contribution as soon as possible. Brazil recently paid its arrears in full for 2015 and 2016 and its assessed contribution for 2017. Thus, as of April 5, 2017, the remaining arrears for all member states at the OAS were lowered to just over $7 million. State officials told us that on April 28, 2017, Venezuela officially notified the OAS of its intent to withdraw from the organization. According to OAS officials, the OAS currently lacks a mechanism to penalize member states for not paying assessed contributions, unlike the other three organizations. OAS officials told us that OAS committees are discussing the potential for defining negative consequences for member states in arrears. According to State officials, the OAS's next opportunity to discuss quota structure reform at the ministerial level will be at its General Assembly meeting in Mexico City in June 2017. The Mexican government announced that the main theme of the meeting will be strengthening dialogue and cooperation in the OAS. State officials said that high-level engagement between member states' officials will be needed to promote quota structure reform. They informed us that efforts to reform the assessed quota structure continue at the working level and that they are seeing some progress toward reform. We provided a draft of this report for comment to State, the Departments of Agriculture and Health and Human Services, the U.S. Agency for International Development, the OAS, PAHO, IICA, and PAIGH. The Departments of Agriculture, Health and Human Services, and the U.S. Agency for International Development stated that they did not have any comments on our report. State provided technical comments, which we incorporated as appropriate. As agreed with your office, unless you publicly announce the contents of this report earlier, we plan no further distribution until 30 days from the report date.

Contact points for our Offices of Congressional Relations and Public Affairs may be found on the last page of this report. GAO staff who made key contributions to this report are listed in appendix III. This report responds to a request for GAO to review several issues related to the Organization of American States (OAS), the Pan American Health Organization (PAHO), the Inter-American Institute for Cooperation on Agriculture (IICA), and the Pan-American Institute of Geography and History (PAIGH). In this report, we (1) determine the amounts and percentages of U.S. contributions assessed by these organizations and voluntary contributions paid to them in calendar years 2014 to 2016, and (2) describe the Department of State's (State) efforts to comply with requirements in the Organization of American States Revitalization and Reform Act of 2013 (Reform Act) regarding a strategy for reform of the assessed quota structure of the OAS. To determine the amounts and percentages of contributions assessed by the OAS, PAHO, IICA, and PAIGH to the United States and other member states, as well as the amounts and percentages of additional voluntary contributions paid to these organizations, we reviewed externally audited budget reports for calendar years 2014 and 2015. For calendar year 2016, we reviewed budget documents from the four organizations and corroborated the accuracy of the data with the organizations and the U.S. agencies that provide funds to these organizations. For assessed contributions, we reviewed the organizations' assessed quota structures. We report the quota structure percentage assessed to the United States over these 3 years and the corresponding United States' assessed contribution amounts for this same time period, based on our analysis of data provided by the organizations. We determined the 2014 and 2015 data to be sufficiently reliable for the purpose of reporting the United States' assessed contributions and quota percentages because these data had been externally audited. To determine the reliability of the 2016 data, we reviewed budget documents that have not yet been audited, discussed these data with knowledgeable officials at the organizations and U.S. agencies, and corroborated them with these officials and U.S. agencies. We determined the data were sufficiently reliable for the purpose of reporting the United States' assessed contributions and quota percentages in 2016. These data reflect the quotas assessed to the United States and do not reflect total payments made by the U.S. government to the organizations' regular budget, which include other miscellaneous payments. For voluntary contributions, we reviewed the same externally audited reports and data from the organizations to obtain the amounts contributed by member states and calculated the proportion of the United States' voluntary contributions compared with those of the other member states. The four organizations under review have different categories of voluntary funds, depending on their source and intended use. For consistency purposes, we worked with State and officials from the OAS, PAHO, and IICA to establish our definition of voluntary contributions as funds given from governments to the organizations for implementing specific projects outside their respective countries. In accordance with this definition, we considered the following categories of voluntary contributions: "specific funds" at the OAS, "government financing of voluntary contributions" at PAHO, and "external resources by financing source" for each member state at IICA. We determined the 2014 and 2015 data to be sufficiently reliable for the purpose of reporting the United States' voluntary contributions as a percentage of all members' voluntary contributions because they had been externally audited. To determine the reliability of the 2016 data, we reviewed budget documents that have not yet been audited, discussed these data with knowledgeable officials at the organizations and U.S. agencies, and corroborated them with these officials and U.S. agencies. We determined that the data were sufficiently reliable for the purpose of reporting the United States' voluntary contributions as a percentage of all members' voluntary contributions in 2016. To describe State's efforts to comply with the Reform Act, we analyzed documents from State regarding its strategy for reform of the assessed quota structure in response to the Reform Act. We also interviewed officials from the U.S. Mission to the Organization of American States, State's Bureau of International Organization Affairs, and the OAS Secretariat for Administration and Finance. We conducted this performance audit from July 2016 to June 2017 in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives.

Summary:
The United States belongs to several inter-American organizations, including the OAS, PAHO, IICA, and PAIGH, which promote democracy, security, health care, agricultural development, and scientific exchange in the Western Hemisphere. The United States helps finance these organizations' operating expenses through assessed contributions (fees) that are based in part on the size of the U.S. economy relative to those of other members. The Reform Act required State to submit a strategy identifying, among other things, a path toward the adoption of reforms to the OAS's assessed quota structure to ensure that no member will pay more than 50 percent of OAS assessed contributions. In addition, the United States also provides the OAS, PAHO, and IICA with project-specific voluntary contributions. GAO was asked to review U.S. financial contributions to these four organizations. In this report, GAO (1) determines the amounts and percentages of U.S. contributions assessed by these organizations and voluntary contributions paid to them in calendar years 2014 to 2016, and (2) describes State's efforts to comply with the Reform Act's requirements regarding a strategy for reform of the assessed quota structure of the OAS. GAO analyzed documents and interviewed officials from State, the Department of Health and Human Services, the U.S. Agency for International Development, the U.S. Department of Agriculture, and the four organizations. GAO also analyzed the four organizations' annual audited financial reports. The United States' assessed contributions constituted over 57 percent of total assessed contributions by member states to four inter-American organizations from 2014 to 2016. These organizations are the Organization of American States (OAS), the Pan American Health Organization (PAHO), the Inter-American Institute for Cooperation on Agriculture (IICA), and the Pan-American Institute of Geography and History (PAIGH). During this time, the annual U.S. percentages (or quotas) of these organizations' assessed contributions have remained about the same. The United States also provided voluntary contributions to three of these organizations, as shown in the table. In response to a requirement in the Organization of American States Revitalization and Reform Act of 2013 (Reform Act), the Department of State (State) submitted to Congress a strategy that included working with OAS member states toward ensuring that the OAS would not assess any single member state a quota of more than 50 percent of all OAS assessed contributions. State officials told GAO that reaching member state agreement on assessed quota reform by 2018 will be difficult, although not impossible. State officials informed GAO that State continues to implement a strategy that includes engaging with other OAS member states, such as Canada and Mexico, to explore assessed quota reform options. For example, State officials have consulted with their counterparts from Mexico to review the OAS's assessed quota structure and to consult on alternatives that would adjust all member states' quotas so that no member state's quota exceeds 50 percent of the OAS's assessed contributions. According to State and OAS officials, obstacles to assessed quota reform include tensions among member states. For example, State officials noted that Venezuela's contentious political relationship with the OAS has hindered progress on various reforms, including assessed quota reform. State officials explained that some member states' failure to fully pay assessed contributions from previous years and smaller member states' reluctance to increase their annual assessed contributions have also impeded assessed quota reform efforts.
