TBM Carriers, Inc. and its affiliate, TBM Carriers de Mexico S.A. de C.V., have initiated legal proceedings against Obsidian Insurance Company, disputing a recent collateral increase of $303,000 that has raised significant concerns over premium audits and the handling of claims expenses.
Filed on July 13, 2026, in the federal district court of Texas, the lawsuit seeks declaratory relief, damages, and an injunction against Obsidian for what the plaintiffs describe as an improper escalation of collateral requirements. They allege that Obsidian not only failed to refund overpaid premiums but also neglected to accurately account for specific claims-related expenses.
The Background of the Dispute
The conflict revolves around a large-deductible trucking liability program that secures a fleet of nearly 200 trucks operating across Mexico and the United States. As laid out in the complaint, the original insurance agreement mandated a $350,000 letter of credit to cover deductible obligations and related claim expenses. This sort of insurance structure is not uncommon in the trucking industry, where providers often require considerable capital reserves to buffer against potential claim costs.
However, the plaintiffs claim that in June 2026, following the conclusion of the second policy year, Obsidian unjustly demanded an increase in collateral by an extra $303,000. This raised the total collateral requirement to $653,000. The trucking companies assert that there was no contractual justification for this increase, particularly given Obsidian's announcements regarding its withdrawal from the trucking insurance market, a move that might indicate broader issues within its underwriting practices. They are requesting a court order to prevent the insurer from accessing the existing letter of credit or enforcing the disputed increase during the litigation process. Such a request highlights the ongoing tension between insurers' rights to adjust terms and carriers' need for predictability in their cost structures.
Premium Audit Concerns
This case underscores significant issues regarding premium audits and pricing based on exposure. The plaintiffs argue that premiums for both the trucking liability and commercial general liability policies were determined using estimated fleet mileage, subject to subsequent auditing. They allege that actual mileage was considerably lower than anticipated, leading to premium overcharges. In an industry where profit margins can be tight, overcharging by even a small percentage can have outsized implications on a company's financial health. The plaintiffs state that the amount at stake could range from at least $339,212 to about $1.47 million, dependent on differing interpretations of policy provisions. It's a stark reminder that inadequate audits can contribute to substantial financial disparities between insurers and insured parties.
They also mention that while Obsidian issued a premium credit of $171,992, this was allegedly set against a prior premium rather than refunded to them. Such practices can create distrust and may complicate relationships between insurers and policyholders. If you’re working in this space, you know that transparency in premium calculations is paramount to maintaining a healthy insurer-insured relationship.
Issues of Policy Language and ALAE
The lawsuit further scrutinizes policy language related to premium audits. The plaintiffs cite a provision mandating a final audit within 180 days following the end of a coverage period to determine earned premiums based on actual exposures and to refund any unearned premiums due. They claim this obligation was ignored by Obsidian, which raises questions about compliance with standard auditing practices in the industry.
The complaint also highlights disputes over allocated loss adjustment expenses (ALAE). The policies define ALAE as costs directly associated with claims, encompassing areas like attorney fees, expert costs, and court expenses. According to the plaintiffs, substantial ALAE was incurred under the large-deductible program, yet they were not credited for these expenditures, estimating the disputed amount to be roughly $600,000. Such discrepancies aren't just technical—they can hinder the financial viability of a policyholder, especially in industries with high operational risks like trucking. (And this is the part most people overlook.) One mishandled expense can spiral into larger financial obligations that strain a company's resources.
Broader Implications
Alongside contract-related claims, the suit alleges breaches of good faith and fair dealing, violations of the Texas Insurance Code, and unjust enrichment. These allegations point to a wider trend where insured entities are increasingly scrutinizing the actions of insurers, reflecting a growing frustration with traditional practices in the sector. As this litigation progresses, it shines a spotlight on several pressing issues within commercial insurance practices, including collateral management, audit compliance, deductible-program accounting, and the handling of loss adjustment expenses. For insurers, claims administrators, underwriters, brokers, and insurance executives, these topics may resonate strongly as they navigate similar challenges in their operations.
While the case is in its early stages, the outcome may set significant precedents regarding how collateral and premiums are managed and audited in the trucking insurance sector. What this means for you is that the precedent set here could encourage a rethink of audit processes and premium calculations across the industry, potentially leading to regulatory scrutiny or evolving standards that align more closely with actual exposure rather than estimates. If history teaches us anything, it's that such disputes often lead to sweeping changes in market practices.
