To ensure sound management and long-term stability in their operations, organizations track their financial activities (transactions), such as expenses they incur and income they generate. Organizations record their daily transactions, which increase or decrease account balances, in their accounting systems. For example, an organization’s “cash balance” account increases when customers make payments due for goods or services previously provided, while other account balances, such as “accounts receivable” (the amount owed to an organization for goods or services provided), decrease because customers are paying part of what they owed to the organization. At DOD, as seen in figure 1, this daily process of recording transactions in accounting systems occurs at individual DOD components. These components use multiple accounting systems to record and summarize their financial transactions. Each month, quarter, and year, components send summarized financial information to DFAS, the DOD agency that provides accounting support for DOD. DOD’s core financial reporting system consolidates the summarized financial information from individual components into DOD’s department-wide financial information. Financial statements provide information about an organization’s financial position—such as assets (what it owns) and liabilities (what it owes)—as of a certain point in time, in addition to the financial results of its operations—such as revenue (what came in) and expenses (what went out)—over a period of time, such as a fiscal year. Financial statements are prepared based on the summarized, or consolidated, financial information from an organization’s accounting systems. Their reliability depends on there being accurate financial information in the accounting systems. Federal agencies such as DOD combine summarized financial information from their subsidiary organizations (e.g., DOD’s military components—Army, Air Force, Navy, and Marine Corps) to produce consolidated financial statements, as seen in figure 2. Agency management takes steps to ensure that the financial information contained in financial statements is reliable and accurate. Federal agencies submit their financial information to the Department of the Treasury (Treasury), which then combines the information for presentation in the consolidated financial statements of the U.S. government. Reliable and complete financial information is necessary to help agency management and Congress understand the agency’s finances, make informed policy and resource decisions, and hold agency officials accountable for their use of these resources. Accounting adjustments are used to record corrections or adjustments to transactions in an accounting system. They are usually prepared at the end of an accounting period to adjust ending account balances. For example, accounting adjustments can be recorded monthly, quarterly, or annually to record or accrue an activity that is not accounted for in the organization’s accounting systems, such as certain payroll expenses; correct errors identified in processing financial information; record transactions based on the result of reconciliations; record additional information at the request of a subsidiary organization; or record necessary accounting adjustments caused by accounting system limitations or timing differences. Organizations often record such accounting adjustments when preparing financial statements. For example, adjustments to eliminate intragovernmental transactions, such as accounts receivable and sales, may be recorded. These adjustments are particularly necessary to consolidate information from subsidiary organizations and properly present consolidated financial statements. At DOD, components record accounting adjustments within their own accounting systems, and DFAS records adjustments at the consolidated level in DOD’s core financial reporting system. DFAS often has to reformat the summary information it receives from the components’ accounting systems before DOD’s core financial reporting system can accept and process it. To address these or other issues in the financial information it receives as part of the consolidation process, DFAS records accounting adjustments. See figure 3 for an example of where accounting adjustments can be recorded during the consolidation process. DFAS records accounting adjustments both manually and automatically in an accounting system. DFAS personnel record manual adjustments to (1) adjust errors identified during the financial statement compilation process, (2) record necessary accounting adjustments caused by system limitations or timing differences, and (3) prepare required month-end and year-end closing adjustments. System-generated adjustments are automatically recorded in the accounting system without manual involvement. DFAS uses system-generated adjustments when the volume of adjustments needed for a particular purpose is too high and labor-intensive for the adjustments to be recorded manually. For the fourth quarter of fiscal year 2018, DFAS processed 18,521 manual and 181,947 system-generated adjustments at the consolidated level. During the fourth quarter of fiscal year 2018, as noted above, DFAS recorded, at a DOD consolidated level, over 200,000 accounting adjustments in DOD’s core financial reporting system. The large volume of these adjustments is one of the major impediments to DOD maintaining accurate and reliable financial information. While some of these adjustments are expected in the routine course of business, others—such as those DOD records to force account balances to match—are not. We found that DFAS’s lack of reliable business processes and limitations in the source-level accounting systems that DOD components use to process financial information leads them to record adjustments to remove and replace component-submitted financial information in order to force account balances to agree with Treasury balances. The recording of these types of adjustments was identified as a material weakness in DOD’s internal control over financial reporting in its fiscal year 2019 financial statement audit. While DOD has taken steps to address this issue, because of the multitude of contributing factors involved, DOD faces significant challenges in its effort to successfully reconcile its account balances with Treasury and eliminate the need for recording these adjustments. Some manual and system-generated accounting adjustments are expected in the routine course of business and are recurring in nature. For example, elimination adjustments for intragovernmental balances, as previously discussed, are necessary in order to avoid overstating the account balances of subsidiary organizations in the consolidated financial information. The need for these types of adjustments occurs on a regular basis when two or more DOD components enter into business transactions with each other. For example, when the Army purchases weapons from the Defense Logistics Agency, the Army records the transaction as an expense while the Defense Logistics Agency records this transaction as revenue in its accounting system. At the DOD consolidated level, both the revenue and expense reported at the subsidiary level need to be eliminated to avoid overstating revenue and expense for DOD as a whole. These elimination adjustments are routine, expected, and recurring because they must be prepared every time DFAS compiles DOD’s quarterly and annual consolidated financial statements. Other adjustments, such as those DFAS records in order to force account balances to match (forced-balance adjustments) are not expected within the routine course of business. DOD defines a forced-balance adjustment as any amount recorded, usually at a summary level, to eliminate differences between the component’s general ledger balance and Treasury’s control total. Such adjustments, recorded without adequate supporting documentation at the transaction level, are commonly referred to by the accounting community as plugs. Fund Balance with Treasury (FBWT) adjustments are one example of forced-balance adjustments DFAS records to eliminate differences between its cash balances and the amounts Treasury reported. In the federal government, Treasury acts as the government’s bank and keeps an official record of the remaining spending authority for each agency. Consequently, reconciling an agency’s FBWT account with Treasury- reported amounts is similar to an individual reconciling a checkbook to a bank statement. Treasury requires agencies to reconcile their cash balances each month with the balances reported in Treasury’s records. However, DOD generally records adjustments to make its FBWT agree with Treasury’s records rather than performing proper research to identify what caused the differences. (See fig. 4 for more information on forced- balance adjustments.) The use of forced-balance accounting adjustments affects the reliability of an organization’s financial information and may indicate weaknesses within its systems and processes. Over the years, DOD’s practice of recording forced-balance adjustments has been questioned by GAO and by DOD’s auditors. For example, in an audit of the Army General Fund’s reconciliation process for the FBWT account, DOD’s Office of Inspector General (OIG) stated that the Army and personnel in DFAS’s Indianapolis office “make forced-balance adjustments, which are unsupported manual and system-generated adjustments.” GAO and an independent accounting firm both reported similar practices at the Navy and Marine Corps. These audits have repeatedly identified limitations within the source-level accounting systems that DOD components use and the multitude of legacy systems (computer systems that are outdated or that can no longer receive support and maintenance but are still essential for an organization) as the main contributing factors for the use of forced- balance adjustments. DOD’s Financial Management Regulation (FMR) states that a forced- balance adjustment does not represent an adequate reconciliation. Instead, DOD components are required to maintain detailed reconciliation documentation to provide an adequate audit trail. Further, according to the FMR, a reconciliation is not complete until all differences are identified, accountability is assigned, differences are explained, and appropriate adjustments are made to records. These activities are needed to establish an adequate audit trail. Despite this policy, during the fourth quarter of fiscal year 2018, we found that DFAS recorded approximately 36,000, or over 17 percent of the total accounting adjustments, to force the FBWT accounts to agree with Treasury. Out of the 242 fiscal year 2018 fourth quarter accounting adjustments we selected for testing, nine were FBWT forced-balance accounting adjustments related to undistributed collections and disbursements. Based on our review of these adjustments, we found that DFAS continues to rely on forced-balance adjustments to correct the differences between amounts DOD recorded and those that Treasury reported without properly investigating and resolving the differences. Specifically, we found that DFAS systematically recorded forced-balance adjustments to replace information that DOD components submitted with the amounts that Treasury reported without reconciling and researching the causes of differences and making any appropriate adjustments. DFAS indicated that it performs reconciliations on the FBWT accounts when compiling financial statements and researches the causes of any differences arising from these reconciliations after it records the forced-balance adjustments. However, for our sample of nine FBWT forced-balance adjustments related to undistributed collections and disbursements, DFAS was unable to provide evidence that these reconciliations were performed or that the causes of differences were researched or resolved. Rather, DFAS provided a general description of the reconciliation process it expects each of the three DFAS sites to perform. According to DOD officials, DOD has identified some key causes of the long-standing challenges in reconciling its account balances with Treasury. As noted above, many of these challenges are caused by timing issues, limitations in the source-level accounting systems that DOD components use, or the multitude of legacy systems that different DOD components use. To address these challenges, DOD is currently implementing enterprise resource planning (ERP) systems in the military services, such as the Defense Enterprise Accounting and Management System that the Air Force uses. These systems will replace the current legacy systems across DOD with the expectation of a full transition to ERP systems at all military services by 2025, at which point DOD expects the need to record forced-balance adjustments to decrease. OUSD (Comptroller) has a plan for implementing ERP systems at smaller DOD components that also use legacy systems. However, the challenges that legacy systems cause are likely to continue until the ERP transitions are completed and ERP systems are fully implemented at the military services and smaller DOD components. A DFAS official stated that until DOD fully implements the ERP systems, DFAS does not have any plans to modify the current financial management environment to eliminate the recording of these types of adjustments. As noted earlier, as part of the routine course of business certain adjustments will still need to be made following the full implementation of the ERP systems. Along with DOD’s implementing of the ERP systems, DOD officials stated that some DFAS sites, in coordination with various DOD components, have implemented tools to help them reconcile FBWT balances and research the causes of any differences arising during these reconciliations. According to DOD officials, these tools have the ability to produce supporting documentation for management and auditors to use when reviewing FBWT accounts. However, DFAS did not provide supporting documentation for these reconciliations in order for us to verify that they had been performed. Until DOD consistently performs and documents the required reconciliations to identify the causes for these types of adjustments and takes a holistic approach to resolving them, DOD’s financial management issues—such as those associated with FBWT—are likely to continue, resulting in a continued inability to produce reliable and auditable consolidated financial statements. Establishing clear policies and procedures for recording accounting adjustments is crucial for (1) ensuring that accounting adjustments are properly recorded and adequately supported with documentation; (2) identifying the underlying causes for the recording of adjustments; and (3) developing, implementing, and monitoring action plans to reduce the need for accounting adjustments. We found that DOD and DFAS policies and procedures for recording accounting adjustments were insufficient, outdated, and not consistently implemented. Additionally, we found that DOD and DFAS lacked policies and procedures in certain key areas, such as performing cause analyses and developing action plans to reduce the need for accounting adjustments. By not ensuring that policies and procedures are up-to-date and consistently implemented, DOD faces an increased risk that inaccurate, invalid, or unapproved adjustments will be recorded in its core financial reporting system, resulting in misstatements in its consolidated financial statements. System-generated accounting adjustments are recorded automatically in an accounting system and have unique characteristics and processes that differ from those applicable to manual accounting adjustments. Unlike manual adjustments, which are initiated, recorded, and approved in the accounting system by a person, system-generated adjustments are guided by business rules embedded in an accounting system. These business rules drive the accounting adjustment process and are configured to record the adjustment when certain conditions are met. We found that DFAS lacked documentation to support the business rules, such as documentation of programming logic that creates the system- generated adjustments. Based on our review of accounting adjustments at DOD, we found that system-generated adjustments are recorded in large numbers and account for the majority of the accounting adjustments that DFAS recorded. For example, for the fourth quarter of fiscal year 2018, system- generated accounting adjustments accounted for over 90 percent of the total volume of adjustments recorded in DOD’s core financial reporting system at the consolidated level. Given the magnitude and unique characteristics of system-generated adjustments, developing and maintaining adequate supporting documentation are critical. According to the FMR, adjustments to the accounting records should be supported with sufficiently detailed written documentation to provide an audit trail to the source transaction that requires the adjustment. Further, the FMR requires supporting documentation to include information such as the reason for the adjustment, calculation of the adjustment amount, and evidence of managerial review and approval of the adjustment. To support certain types of recurring system-generated adjustments, DFAS developed eight standardized narratives that include the reasons for the adjustments and the documentation DFAS considers necessary to support the adjustments. Other recurring system-generated adjustments are recorded based on System Change Requests, which are proposals to modify information in an accounting system such as revising programming logic and coding changes. In the fourth quarter of fiscal year 2018, DOD determined that 74 percent of the recorded system- generated adjustments related to four of the eight standardized narratives. Most of the System Change Requests we tested related to financial information migration from a legacy system to a new responsible work area for the U.S. Army Corps of Engineers. DFAS annually selects and reviews a random sample of 40 system- generated adjustments related to each type of narrative for which supporting packages are prepared. According to DFAS officials, the supporting package preparation for the selected sample involves verifying that the adjustments impacted the intended accounts. If no issues are identified, DFAS concludes that the core financial reporting system recorded the adjustments as intended, the desired results were achieved, and the adjustments were supported. Within a given year, if DFAS sample testing demonstrates that a certain type of system-generated adjustment was supported, DFAS categorizes all the accounting adjustments that relate to this particular type as supported for the rest of the year. We found that other than the supporting packages created specifically for the periodic random samples, DFAS maintains no other documentation to support the system-generated adjustments related to each of the eight narratives. As part of our audit, we selected for testing 242 accounting adjustments that impacted the financial statements for the fourth quarter of fiscal year 2018, of which 93 were system-generated accounting adjustments. Of these 93 adjustments, DFAS categorized 42 as unsupported and 51 as supported. DFAS categorized adjustments as either supported or unsupported depending upon the circumstances. The circumstances considered include whether it relates to one of the eight narratives or to specific System Change Requests. When the eight narratives are tested, if no issues are identified as part of the testing, the transactions linked to that narrative are considered supported. However, we determined that the corresponding narratives and System Change Requests were insufficient support for the 51 adjustments categorized as supported because we were unable to verify the validity and accuracy of the adjustments with supporting documentation. In addition, we found that DFAS did not maintain evidence demonstrating the review and approval of the programming of predefined business rules in the systems that recorded the adjustments. When our results are projected to the fiscal year 2018 fourth quarter population of 181,947 system-generated adjustments, we estimate that at least 96 percent of the system-generated accounting adjustments were recorded without adequate supporting documentation, which is required by DOD’s policy and procedures and federal internal control standards. In 2018, DFAS’s auditor issued a finding identifying similar issues with DFAS’s system- generated adjustments related to the scope of the eight narratives. As of November 2019, this finding was still open. Standards for Internal Control in the Federal Government requires that management design control activities to achieve objectives and respond to risks, such as designing controls to help ensure accurate and timely recording and maintenance of appropriate transaction documentation. Although the FMR has guidance on supporting documentation requirements for accounting adjustments, we found that DOD’s FMR does not clearly define or include examples of what constitutes adequate supporting documentation of system-generated accounting adjustments. Specifically, the FMR does not differentiate between documentation requirements for manual and system-generated accounting adjustments. Rather, it states that reporting organizations must maintain adequate documentation, audit trails, and internal controls, and that the documentation must be made available upon request. Because system- generated accounting adjustments consist of summary-level financial information, DFAS officials stated that maintaining documentation at a detailed level would be impractical given the large volume of transactions at DOD. However, without adequate supporting documentation for the business rules driving the recording of these adjustments, such as documentation of the programming logic for these adjustments, management and others cannot determine whether an adjustment was recorded for a valid reason or for the correct amount. The March 2002 version of the DOD’s FMR, volume 6A, chapter 2, established 10 category codes that are used to identify the circumstances under which accounting adjustments may be recorded. For example, DFAS uses category A for reversing entries for a prior reporting period and category B for data call adjustments. Additionally, the FMR specifies the required documentation needed to support each category. For example, for category A adjustments, adequate documentation includes information on the original entry and a statement that the adjustment is a reversing entry, whereas for category B adjustments, documentation requirements include information on the summarized amount and identification of the source or location of the transaction-level detail for the adjustment. DOD’s core financial reporting system is designed to allow a DFAS accountant to select one of these 10 codes when recording an adjustment. Since these codes are used to identify the required documentation to support the adjustments, it is important that the codes are periodically reviewed to ensure that they are still relevant in DOD’s current financial reporting environment and that supporting documentation requirements are appropriate. We found that some of the category codes were rarely used and new codes may need to be added to reflect the current financial reporting environment. For example, we found that of the 18,521 manual adjustments recorded in DOD’s core financial reporting system during the fourth quarter of fiscal year 2018, category F (supply management inventory) was used only four times. According to DFAS officials, this code was primarily used to adjust the purchase cost of certain supplies, but those adjustments are now rarely needed. DFAS officials stated that the codes had not been reviewed for continued relevance since they were first established and expressed a need to revisit the current categorization scheme to determine whether the codes should be redefined. The most recent update of FMR, volume 6A, chapter 2, in June 2019 included the addition of category M, the first code added since 2002. According to DFAS officials, this code was not added based on a thorough review of the existing codes but because there was already a substantial volume of data call adjustments taking place in the Data Collection Module. Further, a DOD official suggested that an additional code may be needed for tie-point adjustments, which DFAS accountants frequently record as a result of tie-point reconciliation. We found that 34 of the 149 manual accounting adjustments we tested related to tie-point adjustments. Because there is not a designated category code for tie-point adjustments, we found that accountants used various other category codes when recording the 34 tie-point adjustments, including D (Recognition of Undistributed Disbursements and Collections), E (Reconciliation of Trial Balance and Budget Execution Reports), G (Reclassification of Accounts), H (Identified Errors and Reasonableness Checks), I (Adjustment to Balance Reports Internally), or at times no category code. As a result, there may be inconsistency in the documentation maintained to support tie-point adjustments. Having a single category code for tie-point adjustments could standardize recording by accountants, enabling DFAS to identify the frequency with which tie- point adjustments are recorded and ensure that it maintains adequate supporting documentation. Standards for Internal Control in the Federal Government requires that management implement control activities through policies. To do this, management periodically reviews policies, procedures, and related control activities for continued relevance and effectiveness in achieving the organization’s objectives or addressing related risks. The DOD FMR Revision Standard Operating Procedures indicates that the FMR is reviewed every 2 years. However, based on our discussion with DOD officials, a thorough review of the category codes has not been performed and is needed to ensure the ongoing applicability of current category codes or the need for additional codes to reflect the current financial reporting environment. Without category codes for accounting adjustments that reflect current business needs, there is an increased risk that the reasons for recording these adjustments will not be properly captured and adequate supporting documentation will not be specified or maintained, hindering DFAS’s ability to provide DOD management or auditors with reliable information about recorded accounting adjustments. The FMR identifies critical elements that need to be included as part of the supporting documentation package when recording manual accounting adjustments. These elements include (1) correct appropriation and accounting information, (2) balanced adjustments, (3) approvals, (4) supporting documentation, and (5) valid U.S. Standard General Ledger (USSGL) account numbers. The FMR further states that supporting documentation included in the package must include, among other things, elements to enable the assessment of the (1) accuracy and completeness of financial information recorded, (2) applicable criteria to support the reason for recording the adjustment, (3) specific expenditure or receipt accounts used, and (4) calculation of the dollar amount of the adjustment. For the fourth quarter of fiscal year 2018, we selected a sample of manual and system-generated adjustments to determine if the supporting documentation for these adjustments included the critical elements described in DOD’s FMR. We found that DFAS accountants did not consistently follow the DOD FMR and DFAS’s policies and procedures for some of these critical elements, resulting in (1) the failure to maintain adequate supporting documentation, (2) the recording of out-of-balance accounting adjustments, and (3) the use of account numbers that do not comply with the USSGL. Inadequate supporting documentation: We found that 51 of the 87 manual adjustments we reviewed that DFAS categorized as supported did not contain supporting documentation required by the DOD FMR. For example, we found instances where supporting documentation packages were missing information to support the reason for recording the adjustment or detailed worksheets to support the calculation of the adjustment amount. DFAS officials explained that 30 of the 51 adjustments resulted from a major change in how DFAS processes U.S. Army Corps of Engineers’ financial information. Because of time sensitivity and based on a risk analysis, management decided to process over 3,000 manual adjustments for the fourth quarter of fiscal year 2018, including the 30 that were selected for our sample, without preparing supporting documentation for these individual adjustments. We also found that not all supporting documentation packages included a DFAS Form 9339, DFAS Journal Voucher Catalog and Checklist, as required by DFAS’s Interim Policy Memorandum. This memorandum requires that all manual accounting adjustments, whether classified as supported or unsupported by DFAS, include a Form 9339 to help ensure the inclusion of the appropriate supporting documentation. We reviewed 149 manual adjustments and found that 94 included a Form 9339. Our review of these 94 accounting adjustments found that 28 lacked the required information. For example, nine packages did not include one or more of the necessary elements required by Form 9339. We found instances where source information, customer coordination, document labeling, before and after trial balances, narratives, or a combination of these were missing. For six of the nine packages, DFAS agreed that some of the necessary data elements were missing; for the remaining three packages, DFAS’s response did not fully address the reasons for the missing documentation. DFAS officials stated that one of the reasons why these errors may have occurred was because the implementation of the Interim Policy Memorandum was in its beginning stages when we selected our fourth quarter fiscal year 2018 sample. The policy memorandum was dated June 11, 2018, and was effective immediately. We also found that 19 adjustments lacked the required root cause indicator code on the Form 9339. According to DFAS officials, DFAS Cleveland prepared those 19 forms. DFAS Cleveland officials explained that in collaboration with the Navy Financial Management Office, DFAS Cleveland’s senior leadership decided to deviate from the Interim Policy Memorandum and not include the root cause indicator code in the Form 9339 when recording Navy’s related accounting adjustments. Rather, DFAS Cleveland developed its own system to identify root causes by using a unique identifier code. However, the Interim Policy Memorandum does not exclude any DFAS site from adhering to the requirement, and DFAS was unable to provide documentation to demonstrate that DFAS Cleveland had authorization to deviate from this policy. According to DFAS officials, DFAS Cleveland will begin including the root cause indicator code on the Form 9339, starting second quarter of fiscal year 2020. Out-of-balance adjustments: We found that about 2,800 manual adjustments, or approximately 15 percent of all manual adjustments recorded at the DOD consolidated level for the fourth quarter of fiscal year 2018, were out-of-balance. For example, we identified one adjustment in which DFAS decreased its FBWT account by $14,232,000 without recording a change to a corresponding account. DOD’s FMR requires that all recorded accounting adjustments be balanced. Additionally, we found that the FMR does not identify any situations where an out-of-balance adjustment is allowable, despite DFAS officials stating that out-of-balance adjustments are sometimes necessary. Auditors of the military services found that reasons for out-of-balance financial information include (1) service-level general ledger systems are not effectively designed to prevent incomplete transactions from being recorded and (2) controls are not in place at the service level to detect these errors in a timely manner. According to DFAS officials, out-of-balance adjustments are recorded to correct out-of-balance financial information received from DOD components’ accounting systems. Use of non-USSGL-compliant accounts: During our review of fourth quarter fiscal year 2018 manual and system-generated adjustments, we found that over 13,000 adjustments (over 6 percent) recorded at the DOD consolidated level used non-USSGL-compliant accounts, which are not allowed by the Treasury Financial Manual or DOD FMR. The Federal Financial Management Improvement Act of 1996 requires certain federal agencies, such as DOD, to use the specific and standardized set of accounts referred to as the USSGL in their financial reporting systems. Treasury maintains this set of accounts annually to help ensure the comparability of financial information across the federal government. DFAS officials stated that these noncompliant accounts are referred to as memo accounts and were primarily used for management planning purposes. They further explained that DOD had controls in place to prevent financial information recorded in memo accounts in DOD’s core financial reporting system from being transferred into the financial reporting systems, which Treasury uses to compile the U.S. government consolidated financial statements. DOD OIG also reported issues related to DOD’s use of noncompliant accounts, which it identified in fiscal year 2018. In addition, in DOD’s Fiscal Year 2018 Agency Financial Report, management acknowledged that DOD’s financial management systems did not comply with the USSGL at the transaction level. In response, the DOD Deputy Chief Financial Officer issued a memorandum on March 15, 2019, acknowledging that DOD components must use the established USSGL accounts identified in the Treasury Financial Manual for financial reporting purposes. Additionally, the memorandum stated that supporting documentation must be maintained for any accounting adjustments recorded using memo accounts. However, for the seven non-USSGL-compliant adjustments included within our sample of manual and system-generated adjustments, we found that documentation had not been maintained. Proper recording of adjustments is crucial for ensuring that the financial information accurately reflects the financial transactions that have occurred. This includes maintaining adequate supporting documentation and implementing review procedures to help ensure controls are in place to detect errors in a timely manner. Failure to fully adhere to established procedures increases the risk that inaccurate accounting adjustments will be recorded, thereby reducing the reliability of reported financial information and potentially causing misstatements in the DOD consolidated financial statements. Organizations use root cause analysis as a tool to identify and evaluate systems, processes, or both that prompted the recording of an accounting adjustment. For certain adjustments, it may be determined that a root cause analysis or action plan is not necessary—for instance, if the adjustment is onetime or nonroutine. However, information obtained through a root cause analysis may be used to make system or process changes within a specific program, thus reducing the need to record adjustments. Once a root cause has been identified and analyzed, an organization should create an action plan that describes the steps to be taken to address the root cause and monitors the effectiveness of the actions taken. Figure 5 illustrates the identification, implementation, and monitoring of accounting adjustment root causes and related action plans. We found that although DFAS headquarters and its individual sites perform root cause analysis and develop and take some actions to address the identified causes, neither DOD nor DFAS has established policies and procedures that require staff to perform root cause analysis; develop and implement action plans for issues that DFAS staff identified; or monitor the effectiveness of action plans in eliminating the need for accounting adjustments. DFAS officials acknowledged that there are no policies in place requiring DFAS to perform root cause analyses that would permit them to compare root causes for accounting adjustments at a consolidated level across the DFAS sites. DFAS and its sites identify root causes for individual accounting adjustments when accountants select a root cause indicator code when recording the adjustment. DFAS staff also identify root causes for accounting adjustments at an aggregate level when preparing summary metrics on adjustment types. For example, we found that in addition to the requirements previously discussed, Form 9339 requires accountants across all DFAS sites to prepare “white papers/narratives (white papers) each time a manual adjustment is recorded.” Our review of these white papers identified that some DFAS sites use the white papers to document the root cause analyses while others do not because DFAS has not provided a template that identifies the minimum required information to be included in the white papers. As a result, we found that individual DFAS sites do not use standardized white paper templates and that the information included in the white papers was not always consistent between and within the DFAS sites. Inconsistency between DFAS sites: Our review of 52 white papers found that DFAS Indianapolis was the only site to include information such as scope, source system, and financial statement impact of the accounting adjustment in its white papers, while DFAS Columbus was the only site that included corrective actions taken. (See fig. 6.) Inconsistency within a DFAS site: Our review of 52 white papers found that DFAS Indianapolis did not consistently include background, purpose of the adjustment, a description of the root cause, posting logic, financial statement impact, pending action, source system, and scope in all white papers it prepared. Some white papers had these elements and others did not. We found similar issues with the white papers prepared by DFAS Columbus and DFAS Cleveland. Figure 7 illustrates information included in white papers that was inconsistent within a DFAS site. We also found that DFAS does not have policies and procedures requiring the identification and implementation of action plans to address the cause of and need for accounting adjustments that staff identified internally. This resulted in inconsistencies in how the different DFAS sites developed and implemented action plans. For example, we found that 73 of the 98 manual and system-generated unsupported adjustment packages that included a root cause analysis that we reviewed did not include an action plan to address the root cause. Based on this testing, we estimate that at least 88 percent of fourth quarter fiscal year 2018 unsupported adjustments for which a root cause analysis was performed did not have a documented action plan. For the remaining 25 packages with documented action plans, we found that only two included steps documenting how the action plan was to be implemented. The remaining 23 packages with documented action plans lacked implementation details, and DFAS officials stated that they were waiting for resolution from the relevant DOD components. DFAS officials stated that they prepare and document action plans for issues that affect multiple accounting adjustments but not for issues that affect only one adjustment (unique root cause). Unique root causes do not necessitate action plans and are resolved the following month through DFAS working with the affected DOD components. According to DFAS officials, many of the action plans are discussed in biweekly and monthly meetings, but these action plans are not documented. Finally, we found that DOD and DFAS do not have policies and procedures requiring management to monitor the results of action plans that individual DFAS sites prepared or to measure whether implemented action plans are effective in addressing the causes for accounting adjustments. DFAS management activities were limited to periodically reviewing summary metrics on the numbers and types of accounting adjustments recorded. These metrics did not contain detailed information, such as the causes of accounting adjustments to be addressed, accountable officials responsible for implementing action plans, expected time frames for the implementation of action plans, or specific steps to be performed to address the causes. Additionally, the metrics did not include any information on action plans to address system-generated accounting adjustments, which account for the majority of the adjustments. This type of detailed information is critical to DOD management and DOD external stakeholders for evaluating the department’s progress in correcting the issues. GAO has previously reported that a lack of comprehensive information on corrective action plans limits DOD’s and Congress’s ability to evaluate DOD’s progress toward fully, timely, and efficiently correcting its long-standing financial management deficiencies. Office of Management and Budget Circular A-123 requires agencies to perform cause analysis of deficiencies identified to ensure that subsequent strategies and plans address the causes of the problem and not just the symptoms. Additionally, Standards for Internal Control in the Federal Government requires that management implement control activities through policies. To do this, management documents in its policies the internal control responsibilities of the organization. In addition, management periodically reviews policies, procedures, and related control activities for continued relevance and effectiveness in achieving the entity’s objectives or addressing related risks. Without policies that require consistent processes across DOD for identifying and addressing the causes of accounting adjustments, from the identification of underlying root causes to the development, implementation, and monitoring of action plans, it is likely that DOD’s efforts to reduce accounting adjustments will be inefficient and ineffective. The large number of accounting adjustments that are recorded in the preparation of DOD’s financial statements presents audit challenges. To address this issue, DOD and DFAS have established multiple initiatives aimed at reducing accounting adjustments. While these initiatives have resulted in fewer adjustments of certain types being recorded at the component and consolidated levels, the current focus has been on reducing the number of adjustments recorded without adequate supporting documentation within their responsible work areas, not on reducing the need for recording accounting adjustments department-wide. Both DFAS and OUSD (Comptroller) have developed department-wide strategies to decrease accounting adjustments; however, neither DFAS nor OUSD (Comptroller) have developed procedures for implementing the department-wide strategies. Without a clear department-wide approach to reducing accounting adjustments across all DOD components, there is a risk that DOD’s effort to reduce accounting adjustments will be unsuccessful, which in turn hinders its ability to produce reliable and auditable consolidated financial statements. To reduce accounting adjustments, OUSD (Comptroller) and DFAS have undertaken many initiatives over the last few years. In fiscal year 2018, OUSD (Comptroller) determined that a large number of accounting adjustments at the consolidated level resulted from data calls. To decrease the need for recording these adjustments at the consolidated level, DOD established the Data Call Journal Voucher (JV) Migration Initiative with the goal of eliminating data call adjustments in its core financial reporting system to the maximum extent possible. The first phase of this initiative moved the recording of adjustments for the Federal Employees’ Compensation Act (FECA) liability to the DOD component level responsible for the underlying transaction. According to OUSD (Comptroller), this initiative resulted in the successful migration of the recording of the Missile Defense Agency’s FECA liability from DOD’s core financial reporting system to Missile Defense Agency accounting systems in the second quarter of fiscal year 2019, and has set the stage for 19 other components using the same accounting system as the agency to follow suit. Although this initiative may not reduce the overall number of accounting adjustments that DOD records, it will reduce the need for data call adjustments to be recorded at the consolidated level. OUSD (Comptroller) expects this initiative will also enhance the quality of the supporting documentation maintained for these types of adjustments because the underlying transaction-level detail for the adjustments will be available in the components’ accounting systems. Individual DFAS sites have also undertaken their own initiatives that eliminate the need for some accounting adjustments. For example, in fiscal year 2018, DFAS Indianapolis found that some financial information from the Army’s accounting systems was improperly recorded, requiring adjustments to correct the errors when the financial information transferred into the DOD’s core financial reporting system. DFAS Indianapolis staff worked with the Army to resolve the issue. As a result, adjustments are no longer needed at the consolidated level when the information transfers from Army’s system into DFAS’s system. According to DFAS Indianapolis officials, this initiative resulted in a significant decrease in accounting adjustments at the consolidated level for fiscal year 2019. Developing and implementing a DOD department-wide strategy to reduce the need for recording accounting adjustments at the consolidated level requires DOD to identify the underlying root causes and risks associated with accounting adjustments and to prioritize efforts to address them. This involves clearly defining what is to be done, who is to do it, how it will be done, and the time frames for achievement. To address DOD’s many financial management issues, including reducing accounting adjustments, OUSD (Comptroller) and DFAS have developed different strategies and business plans. However, these strategies and business plans do not include clearly defined expected outcomes or procedures for achieving stated goals. OUSD (Comptroller) issued the DOD Financial Management Strategy Fiscal Years 2016–2020 (Strategy) to help achieve a simplified, standard, affordable, auditable, and secure financial environment, which includes the reduction of accounting adjustments. The Strategy’s JV initiative states that “The purpose of this initiative is to determine why unsupported JVs occur and resolve them.” However, we found that the Strategy did not provide clear direction to staff on how to achieve the JV initiative and did not call for a department-wide effort to address accounting adjustments recorded at the consolidated level. The Strategy also acknowledged that excessive adjustments can indicate underlying problems, such as weak internal controls, and may indicate that transactions are not captured, reported, or summarized correctly. However, we found that the focus of the Strategy was on reducing the number of accounting adjustments recorded without adequate supporting documentation rather than on reducing the overall need for recording accounting adjustments department-wide. In addition to following the OUSD’s (Comptroller) Strategy, DFAS management has also developed the Fiscal Years 2017—2021Strategic Plan (Strategic Plan) and Fiscal Year 2018 Annual Business Plan (Business Plan), which include goals for reducing accounting adjustments, supplemented by bimonthly Strategy Updates. For example, DFAS’s November 2017 Strategy Update outlined the Business Plan goals for fiscal year 2018 with regard to internal controls and business processes. In that update, DFAS set broad goals, such as executing plans to support or reduce system-generated and manual adjustments. However, we found that similar to the OUSD (Comptroller) Strategy, neither DFAS’s Strategic Plan nor Business Plan included defined outcomes or clear procedures for accomplishing the stated goals. The primary focus of these goals was also to reduce the number of accounting adjustments recorded without adequate supporting documentation. We found that this lack of clear procedures led each DFAS site and DFAS headquarters to focus their initiatives on accounting adjustments that impacted their responsible work areas instead of reducing the need for recording accounting adjustments overall. According to DFAS site officials, in some instances, reducing the number of accounting adjustments recorded without adequate supporting documentation at their individual sites could have an impact on the need to record adjustments at the consolidated level; however, the effect at the consolidated level was not their primary focus. Standards for Internal Control in the Federal Government requires that management implement control activities through policies. To do this, management documents in its policies the internal control responsibilities of the organization. In addition, management periodically reviews policies, procedures, and related control activities for continued relevance and effectiveness in achieving the entity’s objectives or addressing related risks. Without detailed documented policies and procedures for implementing its initiatives, and a complete understanding of the issues contributing to the recording of accounting adjustments (both supported and unsupported) across DOD, there is an increased risk that management efforts to reduce accounting adjustments at the consolidated level will be ineffective. In the routine course of business, organizations often record accounting adjustments on a monthly, quarterly, and annual basis. Some adjustments are necessary so that financial information is presented meaningfully and accurately. However, an extensive use of accounting adjustments may indicate significant underlying problems. In order to produce reliable financial information that DOD management and Congress can use for decision-making, DOD needs to develop policies and procedures for recording accounting adjustments that are consistently implemented across the department and reflect the current DOD financial reporting environment. DOD also needs to address the issues that contribute to its need to extensively record accounting adjustments by implementing policies and procedures for the consistent identification of the causes for recording adjustments and the development, implementation, and monitoring of action plans to address the identified causes. If DOD does not address these issues, there is an increased risk that its financial information will be misstated and DOD will continue to be unable to prepare reliable and auditable consolidated financial statements. We are making the following eight recommendations to DOD: The Director of DFAS should, in accordance with the FMR, implement procedures to help ensure that FBWT reconciliations are consistently performed and that all DFAS sites review and document research conducted on the causes of any differences arising from these reconciliations. (Recommendation 1) The Under Secretary of Defense (Comptroller) should update the FMR to clearly define the required supporting documentation for system-generated accounting adjustments, including the required documentation of business rules driving the recording of these adjustments, such as documentation of the programming logic. (Recommendation 2) The Under Secretary of Defense (Comptroller) should perform and document a comprehensive review of the FMR accounting adjustment category codes to determine their ongoing applicability or the need for additional codes to reflect the current financial reporting environment. (Recommendation 3) The Under Secretary of Defense (Comptroller) should establish procedures to help ensure the consistent implementation of the requirements of DFAS Form 9339. (Recommendation 4) The Under Secretary of Defense (Comptroller) should update policies and procedures to identify the causes of out-of-balance accounting adjustments and resolve the causes in a timely manner. (Recommendation 5) The Under Secretary of Defense (Comptroller), in conjunction with the Director of DFAS, should develop and implement policies and procedures to help ensure that root cause analyses for accounting adjustments are consistently performed and documented across DOD. (Recommendation 6) The Under Secretary of Defense (Comptroller), in conjunction with the Director of DFAS, should develop and implement policies and procedures to help ensure consistent development, implementation, monitoring, and documentation of action plans across DOD that address accounting adjustment causes that staff identified internally. (Recommendation 7) The Under Secretary of Defense (Comptroller), in conjunction with the Director of DFAS, should develop and implement procedures across DOD that include clearly defined outcomes focused on reducing accounting adjustments (supported and unsupported) with specific actionable steps and procedures for achieving stated goals. (Recommendation 8) We provided a draft of this report to DOD for review and comment. In written comments, DOD concurred with all eight of our recommendations and cited actions to address them. DOD’s comments are reproduced in appendix II. As agreed with your office, unless you publicly announce the contents of this report earlier, we plan no further distribution until 11 days from the report date. At that time, we will send copies of this report to the appropriate congressional committees, the Secretary of Defense, the Under Secretary of Defense (Comptroller), the Director of the Defense Finance and Accounting Service and other interested parties. In addition, the report is available at no charge on the GAO website at http://www.gao.gov. If you or your staff have any questions about this report, please contact me at (202) 512-2989 or kociolekk@gao.gov. 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 examines (1) accounting adjustments and their effect on the reliability of the Department of Defense’s (DOD) financial information, (2) the extent to which DOD has established and implemented policies and procedures for recording accounting adjustments, and (3) the extent to which DOD has taken actions to reduce accounting adjustments recorded at the consolidated level. To determine the accounting adjustments recorded and their effect on the reliability of DOD’s financial information, we focused our review on the categories of accounting adjustments that DOD recorded at the consolidated level. We reviewed prior audit reports issued by GAO, DOD’s Office of Inspector General (OIG), and independent public accountants for fiscal years 2015 through 2019 to gain an understanding of the types and categories of accounting adjustments. We also reviewed related policies and procedures, such as DOD’s Financial Management Regulation (FMR); performed walk-throughs of the Defense Finance and Accounting Service’s (DFAS) processing of accounting adjustments; and interviewed DOD officials to gain an understanding of the types of accounting adjustments. Additionally, we obtained and analyzed summary information on the adjustments affecting fiscal years 2017 and 2018 by quantity, dollar value, whether they were manual versus system- generated, and unsupported versus supported. To evaluate the extent to which DOD has established and implemented policies and procedures for recording accounting adjustments, we reviewed relevant notices of finding and recommendation that the independent public accountants and DOD OIG issued related to accounting adjustments for fiscal year 2018. We also reviewed DOD and DFAS policies and procedures and interviewed officials from DFAS and the Office of the Under Secretary of Defense (OUSD) (Comptroller) to identify issues surrounding accounting adjustments and the procedures used to process, review, and approve these adjustments in DOD systems. We also inquired about the procedures used to determine the underlying causes of accounting adjustments, if action plans to address the causes had been developed, and the status of these plans. In addition, we assessed DFAS’s efforts to monitor the effectiveness of its action plans. To determine the specific internal controls DOD had in place over its accounting adjustment processes, we interviewed DFAS officials knowledgeable about the accounting adjustment processes and performed walk-throughs of these processes at DFAS. We evaluated the procedures observed during our walk-throughs and those that DOD officials described to determine whether DFAS recorded adjustments in accordance with established policies and procedures. For issues identified, we interviewed DOD officials to confirm our understanding and determined the reasons for the issues identified. To determine if DOD had designed and implemented internal controls over its accounting adjustment processes, we analyzed the information we obtained through the interviews and walk-throughs using relevant criteria, including the DOD FMR, the Treasury Financial Manual, and our Standards for Internal Control in the Federal Government. We also performed tests of controls on a random sample of 242 accounting adjustments from a population of 200,468 adjustments that DFAS recorded at the consolidated level that impacted the financial statements for the fourth quarter of fiscal year 2018. The selected adjustments were recorded in the Defense Departmental Reporting System (DDRS)— Budgetary (DDRS-B), DDRS—Audited Financial Statements (DDRS- AFS), and DDRS-AFS Beginning Balance Adjustment modules. From the DDRS-B and DDRS-AFS modules, we selected a random sample of 225 accounting adjustments, and from the DDRS-AFS Beginning Balance Adjustment module we selected all 17 accounting adjustments. From the three different sets of data, we stratified the selected accounting adjustments into six strata (see table 1). Of the total 242 adjustments, we selected all 17 adjustments in stratum 1, and 45 adjustments each from strata 2 through 6 for testing. We designed the sample to support estimation for all supported accounting adjustments with a margin of error no greater than plus or minus 11.7 percentage points at the 95 percent level of confidence, estimation for all unsupported accounting adjustments with a margin of error no greater than plus or minus 11.8 percentage points at the 95 percent level of confidence, and estimation overall for all accounting adjustments with a margin of error no greater than plus or minus 8.4 percentage points at the 95 percent level of confidence. Because we followed a probability procedure based on random selections, our sample is only one of a large number of samples that we might have drawn. Since each sample could have provided different estimates, we express our confidence in the precision of our particular sample’s results as a 95 percent confidence interval (e.g., plus or minus 8 percentage points). This is the interval that would contain the actual population value for 95 percent of the samples we could have drawn. For the accounting adjustments in our sample that DOD considered supported, we reviewed underlying documentation to determine whether the adjustments were properly supported and contained all critical elements required by DOD policy. We then shared the results of testing with DOD and incorporated any applicable additional information DOD officials provided into our analysis, as appropriate. As part of our testing, we also reviewed documentation related to unsupported accounting adjustments selected in our sample and interviewed DFAS officials to determine if DOD had performed root cause analyses, developed action plans to address the identified causes, and taken any actions in response. We then shared the results of testing with DOD and incorporated any applicable additional information DOD officials provided into our analysis, as appropriate. To assess the reliability of the accounting adjustment information we received from DOD, we conducted interviews with relevant agency officials, compared summary-level dollar amounts and quantities to another DOD information source, performed electronic testing of the financial information, and reviewed related internal controls. On the basis of this work, we found the financial information to be sufficiently reliable to project results of our random sample testing to the population of accounting adjustments for the fourth quarter of fiscal year 2018. Margins of error varied depending on the specific stratum being projected and are disclosed with all estimates contained within the report. To determine the extent to which DOD has taken actions to reduce accounting adjustments recorded at the consolidated level that may affect the reliability of its financial information, we interviewed officials from DFAS and the OUSD (Comptroller) to identify initiatives aimed at reducing accounting adjustments. We further inquired about what tools DFAS used to measure its progress and analyzed summary metrics provided from fiscal years 2017 to 2018 to determine the effect of these efforts on the number of accounting adjustments recorded during these periods. We conducted this performance audit from November 2018 to January 2020 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.

DOD remains the only major federal agency that has been unable to obtain a financial statement audit opinion. One of the contributing factors is DOD's large volume of nonroutine accounting adjustments, which are used for recording corrections or adjustments in an accounting system. This report examines accounting adjustments and their effect on the reliability of DOD's financial information, the extent to which DOD has established and implemented policies and procedures for recording accounting adjustments, and the extent to which DOD has taken actions to reduce adjustments recorded at the consolidated level. For this report, GAO reviewed DOD and DFAS's policies and procedures, interviewed DOD officials about the adjustment process, and reviewed initiatives to reduce the number of adjustments being recorded. GAO also selected a random sample of 242 adjustments recorded at the DOD consolidated level for the fourth quarter of fiscal year 2018 to determine whether the adjustments were recorded in accordance with established policies. While the use of accounting adjustments is a common practice, the Department of Defense's (DOD) reliance on a large volume of nonroutine adjustments to prepare its financial statements is primarily a result of deficient business processes and limitations in accounting systems that DOD components use to process financial information. For example, the Defense Finance and Accounting Service (DFAS) continues to rely on forced-balance adjustments to replace the financial information that DOD's components submit to force agreement with Department of the Treasury balances without reconciling and researching the cause of differences (see figure). The recording of these adjustments was identified as a material weakness in DOD's internal control over financial reporting in its fiscal year 2018 financial statement audit. GAO found that DOD and DFAS policies and procedures for accounting adjustments are insufficient, outdated, and inconsistently implemented. For example, DOD's current policies do not define what constitutes adequate supporting documentation for system-generated adjustments, nor have DOD and DFAS established policies for identifying the cause of the adjustments, developing and implementing action plans to reduce the need for adjustments, and monitoring the effectiveness of those action plans. Because DOD and DFAS are not ensuring that their policies and procedures are up-to-date and consistently implemented, there is an increased risk that inaccurate, invalid, or unapproved adjustments will be recorded in DOD's core financial reporting system, resulting in a misstatement in DOD's consolidated financial statements. DOD and DFAS have undertaken initiatives to address some of the issues that contribute to the need for adjustments. Both organizations have developed strategies to decrease adjustments; however, neither has developed specific outcomes or detailed procedures for achieving stated goals in the strategies. Without clear procedures on how to implement its initiatives and a complete understanding across DOD of the issues contributing to the need for accounting adjustments, there is an increased risk that management efforts to reduce adjustments at the DOD consolidated level will be inefficient and ineffective. GAO is making eight recommendations to DOD, which include updating and implementing policies and procedures on recording accounting adjustments and identifying steps to reduce the need for recording adjustments across the department. DOD agreed with all eight recommendations and cited actions to address them.
