Your client worked nine months as a static security operator outside Kabul. His pay stubs show $9,200 a month. Of that, $4,800 is base hourly wage, $2,400 is a daily per diem for housing and meals he never spent (he lived on a fortified compound with a chow hall), and $2,000 is a hostile-fire uplift the prime contractor paid for working a designated combat zone. He blew out his knee on a foot patrol. Now the carrier has sent you a compensation rate calculation, and it is built on roughly $4,800 a month, not $9,200.
That gap is the entire fight. Under the Defense Base Act, a claimant's weekly compensation flows directly from his average weekly wage. Cut the AWW in half and you cut every future indemnity check in half. For a permanent partial or permanent total claim that runs for years, the difference between counting the per diem and uplift versus stripping them out can exceed six figures over the life of the claim.
The DBA does not write its own wage rules. It borrows them from the Longshore and Harbor Workers' Compensation Act, specifically Section 10 of the LHWCA, codified at 33 U.S.C. 910. That statute was drafted for dockworkers in the 1920s. Applying it to a private military contractor pulling four income components across two continents is where the litigation lives. This article walks through how AWW is actually computed for overseas contractors, whether per diem and danger-pay uplift count as wages, and how to find the on-point decisions that control your case.
How does Section 10 actually calculate average weekly wage?
Section 10 gives administrative law judges three methods, applied in order. You do not get to pick the one that helps your client most. The statute funnels you down a hierarchy.
Section 10(a) applies when the injured worker was employed in the same job for substantially the whole year before the injury. You take total annual earnings and divide by 260 (a five-day worker) or 300 (a six-day worker), then multiply by the daily figure. It produces a clean number when the work history is stable and continuous.
Section 10(b) is the neighbor method. It applies when the claimant did not work substantially the whole year, but a comparable employee in the same role did. You borrow that comparable worker's earnings. In the overseas contractor world, this method appears constantly because deployments are short, rotational, and rarely span a full year.
Section 10(c) is the catch-all. When neither (a) nor (b) can reasonably and fairly be applied, the ALJ has discretion to arrive at a figure that reasonably represents the claimant's annual earning capacity. For overseas contractors, 10(c) is the dominant method. Deployment-based work, mid-year hires, and unusual pay structures almost always push the calculation into 10(c).
The reason this matters: under 10(c), the judge is not bound to a mechanical formula. The judge looks at earning capacity. That is where carriers and claimants fight hardest, because earning capacity is an argument, not an arithmetic operation. A contractor who worked six months in-theater at $9,200 a month can credibly argue his annual earning capacity reflects that elevated overseas rate, not some blended domestic average.
The choice of method is not academic. Whether per diem and uplift survive into the final AWW often turns on which subsection the ALJ uses and how the judge characterizes each component of pay. The same dollar of per diem can count under one framing and vanish under another.
Does per diem count toward average weekly wage under the DBA?
This is the single most contested AWW question for overseas contractors, and the answer is genuinely fact-dependent. The governing principle comes from the LHWCA definition of wages at 33 U.S.C. 902(13), which since the 1984 amendments includes the reasonable value of any advantage received from the employer that is included for purposes of tax withholding under subtitle C of title 26. (The older, pre-1984 version of the statute spoke of the value of board, rent, housing, or lodging, but Congress replaced that language, tying the inquiry to whether the advantage was treated as taxable income.)
The dividing line that ALJs and the Benefits Review Board apply is whether the per diem represents real compensation for services or a genuine reimbursement for actual expenses. If the worker incurred real out-of-pocket costs and the per diem covered them, it looks like reimbursement and tends to be excluded. If the worker pocketed the per diem because housing and meals were provided free by the employer on a secured base, it starts to look like disguised wages and a claimant has a strong argument to include it.
Several factors push toward inclusion. Per diem paid at a flat rate regardless of actual expenses. Per diem paid even during leave or stand-down periods. Per diem that the worker kept as take-home pay because the contractor housed and fed everyone for free. Per diem reported as taxable income. Each of these undercuts the reimbursement theory and supports treating the money as part of earning capacity.
Factors that push toward exclusion run the other way. Documented receipts. Per diem tied to days actually in-country. Amounts that track government GSA or State Department per diem schedules for the duty station. A clear contractual label as expense reimbursement rather than compensation.
The carrier's wage position in any given case is not something you should assume. Carriers litigate per diem aggressively because excluding it is the cheapest way to suppress the comp rate. The defense argument and the specific decisions a carrier relies on vary by company, by venue, and by the era of the policy. Identifying the actual underwriter behind a claim, and pulling the decisions that carrier and its TPA have litigated, is exactly the kind of work that benefits from tracing a contractor through its many corporate name variations before you ever draft the AWW brief.
How is danger-pay or hostile-fire uplift treated in AWW?
Uplift goes by many names: hostile-fire pay, hazard pay, danger pay, war-zone differential, combat-zone bonus. Whatever the label, it is extra money paid because the work happens somewhere dangerous. Unlike per diem, uplift is much harder for a carrier to recharacterize as a reimbursement, because it does not reimburse anything. It is pure compensation for accepting risk.
That makes the inclusion argument stronger. Uplift is paid for working. It shows up as taxable income. It is part of what the contractor actually earned for the hours he put in. Under a 10(c) earning-capacity analysis, money the worker genuinely earned for performing the job is the heart of what AWW is supposed to capture.
The complication is durational. A carrier will argue that uplift is inherently temporary. The differential only applies while the worker is in-theater, the defense says, so it should not inflate an annual earning capacity that assumes a full year of work. If the contractor would have rotated home after six months to a domestic role at half the rate, the carrier argues the AWW should reflect that blended reality, not the peak in-theater number.
The claimant's counter is that the worker's demonstrated earning capacity, at the time of injury, included the uplift. He was hired into a high-risk, high-pay role. He had every expectation of continuing in that role. The injury, not some natural rotation home, is what ended the elevated earnings. Section 10(c) asks what the worker could reasonably have earned, and at the moment of injury that figure included the danger pay.
Concurrent or sequential employment complicates this further. A contractor who held overlapping roles, or who moved between employers mid-deployment, can have AWW components that are easy to miss entirely. We cover that scenario in depth in our analysis of how concurrent employment affects DBA claims when a client worked for multiple overseas employers. The same evidentiary discipline applies: every income stream the worker had at the time of injury is potentially part of the AWW, and missing one quietly suppresses the rate.
Why do overseas wage calculations almost always fall under Section 10(c)?
The structure of overseas contract work fights the assumptions Section 10(a) and 10(b) were built on. Section 10(a) presumes a stable, year-long, same-employer work history. Deployments do not look like that. A typical security or logistics contractor rotates in for a fixed tour, takes leave back home, and may switch primes between assignments. The continuous-employment premise of 10(a) rarely holds.
Section 10(b) presumes you can find a comparable worker who did work the whole year in the same role. In niche overseas roles, a true comparable can be hard to identify and even harder to get earnings data for. Carriers and claimants both struggle to produce a clean 10(b) comparator.
So the calculation lands in 10(c), where the judge constructs a figure that fairly represents annual earning capacity. This discretion cuts both ways. A skilled claimant's attorney uses 10(c) to argue the full in-theater package, per diem and uplift included, reflects real earning capacity. A skilled defense attorney uses the same discretion to argue for a deflated, blended, or annualized-down number.
The evidence that wins a 10(c) argument is documentary and specific. Pay stubs broken out by component. The employment contract showing the pay structure. Tax records showing what was reported as income. Evidence of how long the contractor intended to remain in-theater. Comparable rates for the same role at the same duty station. The party that builds the cleaner record usually controls the AWW.
This is also where injury context matters. Whether the injury even falls under the DBA, and whether it occurred in a covered zone of special danger, can interact with the wage analysis. Our breakdown of DBA coverage for off-duty and recreational injuries overseas shows how the same compound-living facts that bolster a per diem inclusion argument can also drive the coverage question.
What evidence and decisions do you need to win the AWW fight?
Building an AWW case for an overseas contractor is a documents exercise first and a precedent exercise second. On the documents side, you want the complete pay record broken into components, the underlying contract or task order, tax filings, the duty-station per diem schedule, and any evidence of intended tour length. Each piece either supports including a pay component in earning capacity or rebuts the carrier's reimbursement and durational arguments.
On the precedent side, you need decisions on point. The Benefits Review Board and the administrative law judges have issued a large body of rulings on per diem inclusion, uplift treatment, and the choice between Section 10 subsections. ClaimTrove indexes 5,022 OALJ and BRB decisions plus 244 federal circuit court opinions, with full-text and semantic search across the whole corpus. Instead of guessing which rulings address flat-rate per diem on a secured base, you can pull the decisions that actually decided that fact pattern, see how the ALJ characterized each pay component, and cite them directly in your brief.
Knowing which carrier you are fighting changes the research, too. Different carriers and third-party administrators have litigated AWW differently across different eras and contracts. The injury rate and claims posture of the employer also colors how aggressively a carrier defends. Our look at private security contractor injury rates in the DBA data shows why high-volume, high-risk employers tend to generate the most developed body of AWW case law. The more claims an employer and carrier have litigated, the more on-point decisions exist for you to mine.
There is also a documentary trail that helps you confirm the contractor's role, duty station, and contract structure before you ever argue earning capacity. Federal registration and licensing records can corroborate that a worker was performing a specific high-risk function in a specific theater, which feeds straight into the 10(c) analysis. We trace that paper trail in our piece on how ITAR registration creates a carrier paper trail for private military contractors.
The point is that AWW is not a number you accept from the carrier. It is a number you build, component by component, from the record, and defend with on-point precedent. The carrier's calculation is an opening position, not a verdict.
Find the AWW decisions and the carrier behind your claim
The defense will hand you an average weekly wage built on base pay alone and dare you to challenge it. Challenging it well requires two things: the right precedent and a clear view of who is actually on the other side of the claim. ClaimTrove gives you both in one investigation. Run your employer, duty station, and injury date, and the engine identifies the likely DBA carrier and TPA, then surfaces the on-point OALJ and BRB decisions on per diem, uplift, and Section 10 that you can cite to defend the higher AWW. Start an investigation and stop accepting the carrier's number at face value.
