Scenario 01
Indirect Cost Rate — when does it apply?
Setup
An LPA wants to invoice for the public works staff time charged to a federal-aid PE phase. The Finance Director says the LPA has historically charged a 35% indirect cost rate based on the City's Cost Allocation Plan. The PE phase has not had its indirect cost rate reviewed for federal compliance.
Question
Can the LPA invoice with the 35% indirect cost rate? What are the alternatives?
Solution
No — the 35% rate cannot be invoiced without federal approval. Per LAPM Ch 5 §5.3, indirect costs are reimbursable only if the LPA's Indirect Cost Rate Proposal (ICRP) or Indirect Cost Allocation Plan (ICAP) has been approved by Caltrans CIAO before billing.
Options:
1. Submit an ICRP/ICAP for approval. The LPA prepares the proposal under 2 CFR 200 Subpart E, submits to CIAO for review. After approval, the negotiated rate (which may or may not match the LPA's internal 35%) can be invoiced.
2. Use the 15% de minimis rate. Under 2 CFR 200.414, any non-federal entity that has never received a negotiated indirect cost rate may charge a de minimis rate of 15% of Modified Total Direct Costs (MTDC). This is an alternative to a formal ICRP/ICAP.
3. Charge only direct costs. Forgo indirect cost reimbursement for this project.
Key point: The 35% internal rate has no federal authority on its own. It must either be (a) formally approved as an ICRP/ICAP, or (b) replaced with the 15% de minimis rate, or (c) not invoiced.
Common mistake: LPAs assume their cost allocation plan is automatically federally compliant. It isn't. The federal review under 2 CFR 200 is a separate step.

Scenario 02
6-month inactivity → lapsing risk
Setup
An LPA last invoiced a federal-aid project in February 2026. Today is October 5, 2026. The project still has active work in progress, but a billing dispute with a consultant has held up internal invoice processing.
Question
What is the LPA's exposure under the inactivity rule? What action should they take?
Solution
Exposure: LAPM Ch 5 §5.5 invokes the federal Inactive Obligation rule. "If no invoices have been submitted for a continuous period of 6 months, the project is considered inactive." Inactive projects are subject to de-obligation by FHWA.
February 2026 → August 2026 was the 6-month mark. October 2026 means the project has been inactive for ~8 months and is at risk of de-obligation.
Action:
1. Submit a current invoice immediately, even for a small amount. This restarts the inactivity clock.
2. If no reimbursable work has occurred, submit a "no-cost invoice" or written status update to the DLAE explaining the project status (consultant dispute, etc.).
3. Watch the April 1 deadline. Per LAPM Ch 5, all federal funds not invoiced by April 1 of the appropriation lapse year are at risk. Even before formal lapsing, FHWA's inactive obligation review can de-obligate funds.
4. Address the consultant dispute promptly — work that cannot be billed is work that risks the project's federal funding.
FHWA conducts inactive obligation reviews quarterly. De-obligated funds are not recoverable without re-authorization.

Calculation 01
Computing the 2%/$40K withhold
Given
An LPA federal-aid project has $1,850,000 in total federally-participating costs to date. The LPA is preparing its current month invoice for $185,000.
Find
Compute the cumulative withhold per the Master Agreement's 2%/$40K rule. What is the withhold on the current invoice?
Worked solution
Workings
- Master Agreement standard withhold: 2% of cumulative invoiced amount, capped at $40,000.
- 2% × $1,850,000 = $37,000.
- $37,000 < $40,000 cap → use 2% (no cap-cutoff yet).
- Cumulative withhold to date: $37,000.
- Withhold on current invoice: 2% × $185,000 = $3,700 (assuming cumulative remains under $40K cap).
Answer: Cumulative withhold: $37,000. Current invoice withhold: $3,700. The withhold continues at 2% until the cumulative reaches $40,000 (i.e., when total invoiced reaches $2,000,000). Beyond that point, no additional withhold accrues — the $40K cap is the structural maximum. The withhold is released upon Caltrans acceptance of the final invoice and FROE.
Authority: LAPM Ch 5 §5.5; Master Agreement standard withhold clause
Calculation 02
15% de minimis indirect cost rate
Given
An LPA invoice covers $80,000 of direct salary costs and $10,000 of pass-through subcontractor costs. The LPA elects the 15% de minimis indirect cost rate under 2 CFR 200.414.
Find
Compute the eligible indirect cost reimbursement.
Worked solution
Workings
- 2 CFR 200.414: 15% de minimis rate applies to Modified Total Direct Costs (MTDC).
- MTDC excludes pass-through costs above $25,000 per subcontract.
- Here, pass-through is $10,000 (under $25K threshold), so it IS included in MTDC. (If it were $30,000, only $25K would be included.)
- MTDC = $80,000 + $10,000 = $90,000.
- Indirect cost reimbursement = 15% × $90,000 = $13,500.
Answer: $13,500. Note the MTDC exclusions matter: equipment ≥$5K, capital expenditures, rental costs, scholarships/fellowships, participant support costs, and the portion of subawards/subcontracts ABOVE $25,000 are excluded from MTDC. Pay attention to whether subcontract costs cross the $25K threshold per subaward.
Authority: 2 CFR 200.414; 2 CFR 200.68 (MTDC definition); LAPM Ch 5 §5.3
Calculation 03
April 1 lapsing — emergency planning
Given
It is February 15, 2026. An LPA has $145,000 of unspent federal funds on a project authorized in state fiscal year 2020-21. The project is in punchlist phase with construction acceptance expected mid-March 2026.
Find
Is the project at risk of lapsing? What is the timeline pressure?
Worked solution
Workings
- State fiscal year 2020-21 appropriation period: July 1, 2020 - June 30, 2026 (6 years).
- Lapse date: June 30, 2026.
- April 1 deadline: All invoices for funds in this appropriation must be received by April 1, 2026 to be reasonably processable before June 30 lapse.
- February 15 → April 1 = ~6 weeks remaining. Tight.
- Construction acceptance expected mid-March → FROE must be submitted by April 1 to make the lapsing deadline.
Answer: Yes — at significant risk. The April 1 cutoff is the practical "all invoices in" deadline. With construction acceptance in mid-March, the LPA has ~2 weeks to:
• Process final progress invoices.
• Prepare and submit the FROE (a 6-month allowance exists, but here must be much faster).
• Reconcile final costs with CLPA.
• Apply for CWA if extension is needed (would have applied in fall 2024 — too late now).
If invoices arrive after April 1 but before June 30, Caltrans MAY still process them. After June 30, the encumbrance has lapsed and the LPA forfeits the remaining $145,000 — unless a CWA was filed in time (fall of the 5th year — fall 2024).
Note: Some accelerated lapsing rules apply to specific programs. Always confirm with the DLAE.

Audit Finding 01
Read the fact pattern — what's the finding?
Facts
A 2026 CIAO audit reviews invoicing on a closed federal-aid project. The auditor finds that the LPA invoiced $42,000 of consultant indirect costs at a 28% rate. The LPA had submitted an ICRP to CIAO but the ICRP was never formally approved. The LPA proceeded with billing on the assumption that the ICRP was "in process."
Analysis
What is the finding? What is the cost recovery?
Finding · Citation · Corrective action
Finding: Indirect costs invoiced without CIAO approval of the ICRP. LAPM Ch 5 §5.3: indirect costs are reimbursable only if the LPA's ICRP/ICAP has been APPROVED by CIAO before billing.
"In process" is not approval. The 28% rate was not authoritative.
Cost recovery: The $42,000 in indirect costs is ineligible for federal reimbursement. The LPA must:
1. Refund the $42,000 to Caltrans (or have it deducted from final invoice/withhold).
2. Re-bill only the eligible amount under the 15% de minimis rate, OR delay re-billing until the ICRP is formally approved.
Lessons:
1. ICRP approval must be IN HAND before invoicing indirect costs at the negotiated rate.
2. The 15% de minimis is a safe fallback. The LPA could have used 15% while ICRP was in process — that would have been compliant (and recoverable to the actual rate later if higher).
3. CIAO ICRP review takes 6-18 months. Plan accordingly.
Authority: LAPM Ch 5 §5.3; 2 CFR 200 Subpart E
Audit Finding 02
Read the fact pattern — what's the finding?
Facts
An audit of a $2.3M federal-aid construction project finds that the LPA submitted its FROE 9 months after construction acceptance. The Master Agreement and LAPM Ch 5 specify a 6-month FROE deadline.
Analysis
What is the finding? What is the consequence?
Finding · Citation · Corrective action
Finding: Late FROE submission. LAPM Ch 5 §5.6: "The FROE must be submitted within 6 months of construction acceptance." Late submission risks de-obligation of remaining federal funds.
Consequences (variable):
1. Caltrans may have already de-obligated the remaining federal funds. The LPA may have to finance final reconciliation costs with non-federal funds.
2. If the cumulative withhold (2%/$40K) has not been released, the LPA can't access those funds until FROE is processed and final invoice approved.
3. The late FROE becomes a finding in the LPA's history and may affect future Pre-Award audit results.
Corrective action: Submit the FROE immediately with explanation for the delay. Request that Caltrans process final reconciliation if remaining funds are still encumbered.
The FROE must be signed by the LPA's person in responsible charge (LAPM Ch 17). Common reasons for late FROE: outstanding consultant invoices, unresolved CCO claims, materials test reports not yet returned. Address these proactively during punchlist, not after acceptance.

Document Drill 01
LAPM 5-A invoice structure
Drill
List the required elements of a complete LAPM 5-A invoice submission for a federal-aid project.
Model answer
LAPM 5-A Invoice required elements (LAPM Ch 5 §5.5):
1. Invoice header: Project number(s) (federal project number and state project number), LPA name, Locode, invoice period (calendar month), invoice sequence number, date of submission.
2. Billing detail by phase: PE, R/W, R/W-Utility, Construction, CE — separate billing line for each authorized phase under the PSA.
3. Cost detail: Direct costs (force account labor, materials, equipment, consultant invoices), indirect costs (at approved ICRP/ICAP rate or 15% de minimis), and any flexible match contributions.
4. Cumulative-to-date column: Phase total to date, this invoice, cumulative remaining authorization.
5. Federal reimbursement calculation: Apply pro rata rate (or lump sum logic). Subtract 2%/$40K cumulative withhold.
6. Effective PE Reimbursement Date (Section 1440 only): Required on invoices invoking At-Risk PE.
7. Supporting documentation: Consultant invoices, force account timesheets with project number, materials invoices, DBE participation tracking.
8. Certification: Signed by responsible charge or designee, certifying costs are allowable per 2 CFR 200 federal cost principles.
9. Payee Data Record (STD 204): Required for first invoice on a Locode. Updated when payee information changes.
Submission: Monthly is required for active projects. Quarterly is acceptable only with DLAE pre-approval.
