Required Supplementary Information

Required supplementary information (RSI) is information that GASB has determined is essential for placing the basic financial statements in an appropriate operational, economic, or historical context. RSI accompanies—but is not part of—the basic financial statements and is subject to limited audit procedures rather than a full audit opinion.

Blueprint Coverage

BAR Area III, Group A, Topic 8 – Required supplementary information (RSI) other than management's discussion and analysis. Representative task: Recall the objectives and components of RSI other than MD&A in the annual comprehensive financial report (ACFR) for state and local governments.


Where RSI Fits in the ACFR Structure

The Annual Comprehensive Financial Report (ACFR) follows a specific ordering that determines where RSI appears relative to the basic financial statements.

PositionContentStatus
Before basic FSManagement's Discussion & Analysis (MD&A)RSI
Basic FSGovernment-wide, fund statements, notesAudited
After basic FSBudgetary comparisons, pension/OPEB schedules, infrastructure conditionRSI
Exam Tip

Remember the mnemonic "MD&A before, everything else after." MD&A is the only RSI that precedes the basic financial statements. All other RSI follows the notes.


RSI Other Than MD&A – Key Categories

CategoryGoverning StandardWhen Required
Budgetary Comparison SchedulesGASB 34General Fund and major special revenue funds with legally adopted budgets
Pension SchedulesGASB 67/68All governments with defined benefit pension plans
OPEB SchedulesGASB 74/75All governments with defined benefit OPEB plans
Infrastructure Condition InformationGASB 34Only when the modified approach is used for infrastructure

Budgetary Comparison Schedules

Purpose and Scope

Budgetary comparison schedules demonstrate the government's compliance with its legally adopted budget. They are required for:

  • The General Fund
  • Each major special revenue fund with a legally adopted annual budget
Presentation Option

Governments may present budgetary comparisons either as RSI or as a basic financial statement. If presented as a basic statement, it is covered by the audit opinion.

Required Columns

ColumnDescription
Original BudgetBudget as initially adopted by the legislative body
Final BudgetOriginal budget adjusted for all legally authorized amendments and transfers
Actual (Budgetary Basis)Results reported on the same basis used for budgeting
Variance (optional)Difference between final budget and actual; encouraged but not required

Key Requirements

  • Actual amounts must be reported on the budgetary basis of accounting
  • If the budgetary basis differs from GAAP, a reconciliation to GAAP must be provided (either on the face of the schedule or in a separate schedule/notes)
  • The schedule should present revenues and expenditures at the legal level of budgetary control
Common Exam Trap

The variance column is encouraged but not required by GASB. Do not select an answer that states variance columns are mandatory.


Pension RSI Schedules (GASB 67/68)

GASB 68 requires employer governments to present two 10-year trend schedules as RSI.

This schedule tracks the components of the net pension liability (NPL) over time.

ComponentDescription
Beginning Total Pension Liability (TPL)Opening balance
+ Service costPresent value of benefits earned during the period
+ Interest on TPLGrowth in liability due to passage of time
+ Changes in benefit termsPlan amendments increasing or decreasing benefits
+ Experience (gains)/lossesDifferences between expected and actual experience
+ Changes in assumptionsEffect of updated actuarial assumptions
− Benefit paymentsBenefits paid to retirees
= Ending TPLClosing balance
Beginning Plan Fiduciary Net PositionOpening plan assets
+ Employer contributionsAmounts contributed by the employer
+ Employee contributionsAmounts contributed by employees
+ Net investment incomeReturn on plan assets
− Benefit paymentsBenefits paid from plan assets
− Administrative expensesPlan operating costs
= Ending Plan Fiduciary Net PositionClosing plan assets
Net Pension Liability (NPL)TPL − Plan Fiduciary Net Position

Key Ratios Presented

Schedule of Employer Contributions

ColumnDescription
Actuarially Determined Contribution (ADC)Amount the actuary calculates is needed
Actual ContributionAmount the employer actually contributed
Contribution Deficiency/(Excess)ADC − Actual Contribution
Covered Employee PayrollPayroll of employees in the plan
Actual Contribution as % of Covered PayrollActual ÷ Covered Payroll

10-Year Requirement

  • Governments must build up to 10 years of data prospectively from the effective date of GASB 68
  • If 10 years are not yet available, present as many years as exist
  • Prior-period data is not restated retroactively
Exam Tip

The 10-year build-up rule is frequently tested. If a government adopted GASB 68 three years ago, it presents only three years of data—not ten.


OPEB RSI Schedules (GASB 74/75)

OPEB (Other Postemployment Benefits) RSI follows a parallel structure to pension RSI.

Required Schedules

ScheduleContent
Schedule of Changes in Net OPEB Liability and Related RatiosMirrors the pension NPL schedule; shows TPL, plan net position, and net OPEB liability over time
Schedule of Employer ContributionsCompares actuarially determined contribution to actual contribution

Key Differences from Pension RSI

FactorPension (GASB 68)OPEB (GASB 75)
Healthcare trend ratesN/AMust disclose assumptions about healthcare cost trends
Discount rate sensitivityPresented in notesPresented in notes
10-year requirementYesYes
Build-up approachProspectiveProspective
Remember

Both pension and OPEB schedules require 10 years of data built up prospectively. The schedules are structurally identical—only the type of benefit differs.


Infrastructure Modified Approach RSI

When Required

This RSI is required only when a government elects the modified approach for reporting infrastructure assets under GASB 34. Under the modified approach, infrastructure assets are not depreciated; instead, the government commits to maintaining them at or above an established condition level.

Required Disclosures

DisclosureDetails
Condition assessment resultsAssessed condition compared to the government's established condition target
Estimated vs. actual preservation costsComparison of amounts estimated to maintain assets vs. amounts actually spent over the last five fiscal years

Condition Assessment Requirements

  • At least three complete condition assessments within the last five fiscal years
  • Assessments must be performed using a consistent methodology
  • Results must demonstrate the government is maintaining infrastructure at or above its established condition level
Exam Alert

If a government fails to meet condition assessment requirements or falls below its target, it must revert to the depreciation method for those infrastructure assets.


Auditor's Responsibility for RSI

RSI occupies a unique position—it is required by GASB but is not audited at the same level as the basic financial statements.

Level of Assurance

ComponentLevel of Assurance
Basic Financial StatementsReasonable assurance (full audit)
RSILimited procedures (no opinion expressed)
Other Supplementary InformationIn-relation-to opinion or disclaimer

Procedures Applied to RSI

The auditor applies certain limited procedures to RSI, including:

  1. Inquiries of management about methods of preparing RSI
  2. Comparison of RSI for consistency with the basic financial statements
  3. Comparison of RSI with relevant audit evidence obtained during the audit

Reporting on RSI

The auditor's report includes a separate RSI section (typically an "Other Matters" paragraph or a dedicated RSI section) that:

  • Identifies the RSI
  • States that RSI is required by GAAP (GASB standards)
  • States that the auditor applied certain limited procedures
  • Explicitly states no opinion or assurance is expressed on the RSI

Departures Requiring Modification

SituationAuditor's Action
RSI is omitted entirelyAdd a paragraph noting the omission
RSI departs materially from GASB guidelinesDescribe the departure in the RSI section
Auditor is unable to complete limited proceduresState that fact in the RSI section
RSI is present and conforms to guidelinesStandard unmodified RSI language
Exam Tip

Omission of RSI does not result in a qualified or adverse opinion on the basic financial statements. It only affects the RSI section of the auditor's report.
