Business and Commercial Litigation

Sixth Circuit affirms veil piercing against shareholder directors who stripped a corporation of assets

U.S. Court of Appeals for the Sixth Circuit · Granite State Insurance Company v. Taylor, No. 25-5700 · Decided September 2, 2026 · Not recommended for publication · Kethledge, Nalbandian and Hermandorfer, Circuit Judges

The Sixth Circuit affirmed a judgment piercing the corporate veil of a closely held mining company and voiding transfers under Kentucky's Uniform Voidable Transactions Act. The court concluded that the shareholder directors dominated the corporation through gross undercapitalization, failure to observe corporate formalities, and diversion of assets, and that multiple badges of fraud attached to the challenged transfers. The court reversed the award entered under Kentucky's unlawful distribution statute, holding that the statute imposes liability "to the corporation" and does not give an outside creditor a direct cause of action. Writing for the panel, Judge Nalbandian reasoned that the court would not read a common law cause of action into a statute that exists alongside that cause of action rather than replacing or embodying it. The damages judgment survived because veil piercing supports joint and several liability. The decision applies Kentucky corporate law and is not recommended for publication.

What it means for your business.

Owners of closely held companies keep their personal assets out of reach by keeping the company genuinely separate from themselves. Fund the business adequately, hold and document meetings, and run every distribution and asset sale through corporate records rather than personal accounts. Money taken out while a significant claim is pending is exactly what invites a creditor to come after the owners individually. Ask your attorney to review your distribution practices and your corporate record book before the next large payout.

A parent company and its wholly owned subsidiary are not the same party for claim preclusion

U.S. Court of Appeals for the Sixth Circuit · Williams v. Mastronardi Produce-USA, Inc., No. 25-1836 · Decided August 28, 2026, one day before this week's research period · Recommended for publication · Stranch, Bush and Murphy, Circuit Judges · On appeal from the Eastern District of Michigan, No. 2:24-cv-13195

The Sixth Circuit reversed a dismissal that had been granted on claim preclusion grounds, holding that a parent corporation and its wholly owned subsidiary are not privies for that purpose. Applying Taylor v. Sturgell, 553 U.S. 880 (2008), the court explained that Taylor "avoided the term privity altogether and focused instead on whether one of the six common-law exceptions" applied, and that none of them reached this corporate relationship. In the panel's words, "Parent companies and their wholly owned subsidiaries do not fit this bill. Each owns separate property, claims, liabilities, and contracts." The practical result is that a plaintiff who sued the parent and lost may bring the same claims against the subsidiary. Judge Bush wrote the published opinion for the panel, which arose from the Eastern District of Michigan.

What it means for your business.

If your business operates through more than one entity, winning a lawsuit as the parent company no longer ends the matter for the affiliates. The same plaintiff may turn around and sue the subsidiary on the same facts. When a claim threatens more than one company in your group, raise two questions with your attorney: whether every affected entity should be brought into the first case, and whether any settlement release names each related company by name rather than the parent alone.

Tax, Federal and Michigan

September 2026 applicable federal rates and the section 7520 rate

Internal Revenue Service · Rev. Rul. 2026-17 · Rates applicable to September 2026

The section 7520 rate for September 2026 is 5.40 percent. The annual applicable federal rates for the month are 4.18 percent short term, 4.49 percent mid term, and 5.12 percent long term. The applicable federal rate sets the minimum interest a loan must carry before the Internal Revenue Service treats the difference as imputed interest or as a disguised gift or distribution. The section 7520 rate is used to value the separate interests in split interest transfers, including annuity, life, and remainder interests.

What it means for your business.

If you are lending money to your company, to a shareholder, or to a family member this month, the note must charge at least the applicable federal rate for its term, or the Internal Revenue Service will treat the shortfall as income or as a gift. These rates change monthly, so the rate is fixed by the month in which you sign, not the month in which you decide. On the planning side, a higher section 7520 rate improves the arithmetic of charitable remainder trusts and of transfers of a residence, and weakens it for grantor retained annuity trusts and charitable lead annuity trusts. If a transfer of business interests or real estate is on your list this fall, ask your attorney whether the month of signing changes the result.

Federal interest rates on underpayments and overpayments hold steady for the fourth quarter

Internal Revenue Service · Rev. Rul. 2026-15, announced in IR-2026-98 on August 21, 2026 · Published in Internal Revenue Bulletin 2026-36, August 31, 2026 · Effective October 1, 2026

The Internal Revenue Service left its quarterly interest rates unchanged for the calendar quarter beginning October 1, 2026. Overpayments carry 7 percent for taxpayers other than corporations and 6 percent for corporations, with 4.5 percent applied to the portion of a corporate overpayment exceeding 10,000 dollars. Underpayments carry 7 percent, and large corporate underpayments carry 9 percent. Interest is compounded daily. The Service determined the rates from the federal short term rate for July 2026, and Rev. Rul. 2026-15 was published in the Internal Revenue Bulletin on August 31, 2026.

What it means for your business.

Underpaying your fourth quarter estimated tax is an expensive way to borrow. Daily compounding at 7 percent, or 9 percent for a large corporate underpayment, is not deductible for most businesses, so the real cost is higher than the headline number. If your company has had a stronger year than you projected, recalculate the fourth quarter payment before October 1 rather than settling up in April. Ask your accountant and your attorney to look together at whether an annualized income installment method reduces the exposure.

Treasury proposes regulations denying tax exemption to private schools that discriminate

Department of the Treasury and Internal Revenue Service · REG-119986-25, RIN 1545-BS05 · Published September 4, 2026 · 91 FR 56811 · Comments due November 3, 2026

Treasury and the Internal Revenue Service proposed a new section 1.501(c)(3)-2 that would deny exemption under section 501(c)(3) to a private school that discriminates on the basis of race, color, or national or ethnic origin in the administration of any educational policy, admissions policy, scholarship or loan program, athletic program, or other school administered or school supported program. The proposal applies the principle that racial discrimination in education violates a fundamental public policy of the United States to all such discrimination, without regard to intent or asserted remedial purpose. Treasury and the Service estimate that approximately 18,000 private schools and 750,000 students could be affected. The proposal would modify Revenue Procedure 75-50 by removing provisions that had permitted race conscious scholarships designed to promote nondiscriminatory policies. The rules would apply to taxable years of private schools beginning after May 31, 2027, and written comments are due November 3, 2026.

What it means for your business.

This reaches further than school administrators. If your company funds scholarships, if your family foundation makes grants to independent schools, or if you sit on a school board, the terms you attach to that money may need to change before the 2027 school year. Restricted gifts written to favor particular groups of students could put the recipient school's exemption at risk under the proposal. Pull your grant agreements and scholarship criteria now and ask your attorney to review them against the proposed standard, and to file a comment if the rule would disrupt a program you support.

Internal Revenue Service urges businesses to secure tax records before a disaster

Internal Revenue Service · IR-2026-104 · Issued September 3, 2026

The Service issued its National Preparedness Month reminder, with specific guidance for business owners. It recommends keeping returns, insurance policies, property titles, and other key records in waterproof and fireproof containers, maintaining electronic backups on secure devices or cloud storage, and photographing or recording valuable property to support a later casualty loss claim. For employers, the Service recommends confirming whether a payroll service provider carries a fiduciary bond, using the Business Tax Account to monitor balances and payment history, and maintaining access to the Electronic Federal Tax Payment System. The release points to Publication 547, Publication 584-B for business casualty losses, and Publication 3067, and it lists the Special Services Hotline at 866-562-5227.

What it means for your business.

The payroll bond point deserves attention beyond disaster planning. If your payroll company fails or misappropriates the funds you send it, you remain liable to the government for the employment taxes, and a fiduciary bond is often the only source of recovery. Ask your provider in writing whether it carries one and for how much. While you are at it, confirm that someone other than your bookkeeper can log in to the Electronic Federal Tax Payment System and to your Business Tax Account, because losing sole access to those credentials creates its own emergency.

Corporate, Transactional and Regulatory

Delaware court shifts legal fees over disappearing messages left running after a litigation hold

Delaware Court of Chancery · ATG Capital Opportunities Fund LP v. Lane, C.A. No. 2026-0447-LWW · Decided September 2, 2026 · Vice Chancellor Lori W. Will · Supplemental letter opinion

Vice Chancellor Will rejected the defendants' unclean hands defense but granted their motion for spoliation sanctions in part. On unclean hands, the court held that although the plaintiff's coordination with a third party was furtive, the doctrine reaches only conduct "so offensive to the integrity of the court that claims should be denied, regardless of their merit," and exists to protect a court of equity rather than to shield fiduciaries from their own inequitable behavior. On spoliation, the court found that the duty to preserve had attached and that leaving automatic deletion enabled on Signal and WhatsApp, particularly after receipt of a litigation hold, was at a minimum reckless. The court declined to impose adverse inferences as moot, and instead awarded the defendants their reasonable attorney fees and expenses incurred in prosecuting the spoliation motion and in pursuing supplemental discovery.

What it means for your business.

Encrypted messaging applications with automatic deletion have quietly become standard in a great many companies, and they are a serious liability the moment a dispute appears on the horizon. Once litigation is reasonably foreseeable, your company has a legal duty to stop deleting, and that duty covers text messages and chat applications on personal phones used for business, not only email on the company server. Failing to do so can cost you the other side's legal fees before anyone reaches the merits. Ask your attorney to prepare a written hold notice you can send the day a claim looks likely, and make certain it tells people in plain terms to switch off disappearing messages.

Federal Trade Commission and 22 states sue Amazon over concealed advertising surcharges

Federal Trade Commission · Complaint filed in the U.S. District Court for the Western District of Washington · Announced August 31, 2026 · Commission vote 2 to 0

The Commission and 22 state attorneys general allege that Amazon concealed surcharges in its digital advertising auctions over a period of roughly seven years. According to the complaint, Amazon represented that it ran a generalized second price auction in which a winning advertiser would pay only slightly more than the next highest bid, while in practice charging Sponsored Products advertisers "their own winning bid close to 80% of the time." The complaint describes internal mechanisms including what Amazon called a soft reserve price surcharge and an invented auction participant, and alleges that the practice was intensified during high volume shopping events. The Commission alleges the conduct affected more than one million brands, including 500,000 small and medium sized businesses, and extracted tens of billions of dollars from advertisers.

What it means for your business.

If your company sells on Amazon and buys Sponsored Products placements, your advertising costs may have been materially higher than the auction rules you were shown would suggest. Take one practical step now: download and preserve your advertising invoices, campaign reports, and account statements going back several years, because platforms do not keep that history available forever. Then ask your attorney whether your company falls within the group the government describes, and whether a separate claim is worth pursuing or whether you are better served waiting for the case to develop.

Comment period extended on the Federal Trade Commission's personalized pricing policy statement

Federal Trade Commission · Docket FTC-2026-1057 · Issued September 3, 2026 · Comments now due September 25, 2026

The Commission extended by seven days the comment period on its proposed enforcement policy statement addressing personalized pricing, moving the deadline from September 18, 2026 to September 25, 2026. The underlying request for comment issued on August 19, 2026. The release defines the subject as "the use of personal data to set prices according to the amount that a company believes an individual consumer is willing to spend." Comments are submitted through the federal rulemaking portal under docket FTC-2026-1057.

What it means for your business.

Many companies personalize prices without describing it that way. If your e-commerce platform, your dynamic pricing tool, or an outside vendor adjusts what a customer sees based on browsing history, device, location, or past purchases, the Commission is now deciding where the line falls between ordinary marketing and an unfair practice. Find out what your pricing software actually does and what customer data feeds it, since the answer often surprises the business owner. The comment window closes September 25, and your attorney can help you file or simply monitor where the policy lands.

Customs and Border Protection opens rulemaking on heightened import supply chain disclosures

U.S. Customs and Border Protection, Department of Homeland Security · Advance notice of proposed rulemaking, RIN 1685-AA47 · Published September 2, 2026 · 91 FR 56408 · Comments due December 1, 2026

Customs and Border Protection is considering amendments to 19 CFR parts 141, 142, 143 and 163 that would substantially expand what importers must disclose about their supply chains. The agency describes three initiatives: enhanced identification data for the parties involved in manufacturing, producing, moving, or exporting goods; technical solutions for tracing supply chains; and collection of the export documentation that foreign exporters must file with their own customs authority before shipping to the United States. The agency states that the objective is to detect and interdict illicit importations, particularly goods illegally transshipped to evade United States customs and trade laws, and it connects the effort to enforcement of forced labor requirements, rules of origin, intellectual property, and product safety. The notice poses 64 questions on scope, feasibility, cost, technology, and possible exemptions for small entities and critical medical products. Comments are due December 1, 2026.

What it means for your business.

If your company imports, plan on disclosing considerably more about who makes and moves your goods, and on producing the export paperwork your foreign supplier filed in its home country. Begin asking suppliers now whether they can and will provide those documents, because a supplier that cannot is a compliance problem you would rather discover during a rulemaking than during a detention at the port. This is an early stage notice, which means the requirements are still being shaped and comment is genuinely useful. Ask your attorney whether your supply agreements give you the contractual right to demand this documentation, and add that right when contracts come up for renewal.

Securities and Exchange Commission proposes to rescind the investment adviser pay to play rule

U.S. Securities and Exchange Commission · Release 2026-85, File No. S7-2026-31 · Issued September 3, 2026 · Comments due 60 days after Federal Register publication

The Commission proposed to rescind Advisers Act Rule 206(4)-5, which prohibits an investment adviser from providing compensated advisory services to a government client for two years after the adviser or a covered associate makes a political contribution to certain elected officials or candidates. The Commission stated that the rule "is operationally challenging to implement, and creates a de facto strict liability standard" that has produced penalties for minor contributions. The proposal would also amend the Advisers Act recordkeeping rule to remove the corresponding provisions. All other requirements under the Advisers Act would remain in place, including the antifraud provisions, fiduciary duties, the compliance rule, and codes of ethics. The comment period runs 60 days after publication in the Federal Register.

What it means for your business.

If your firm advises a public pension plan, a municipality, or any other government client, the rule that can freeze two years of your fee income over a modest political donation may be on its way out. Take care with the timing, because the rule remains fully in force until any rescission becomes final, and the Commission has not committed to that outcome. Keep your contribution preclearance policy exactly as it is for now. Ask your attorney to calendar the comment deadline once the proposal reaches the Federal Register, and to flag the final rule when it issues so that you can relax the policy at the right moment rather than the wrong one.

Securities and Exchange Commission proposes to modernize the rules for registered transfer agents

U.S. Securities and Exchange Commission · Release 2026-81 · Issued September 1, 2026 · Comments due 60 days after Federal Register publication

The Commission proposed a set of changes to the rules governing registered transfer agents, the firms that maintain shareholder records and process transfers of securities. According to the announcement, the proposal "would amend existing rules and forms, would rescind a rule, and would introduce new rules that apply to registered transfer agents and their activities." The Commission states that the changes reflect the technological environment in which transfer agents now operate, including widespread electronic recordkeeping and communications, and the services transfer agents provide to issuers, investors, and other market intermediaries. The proposal addresses transfer agent activity involving electronic communications and distributed ledger technology. The comment period runs 60 days after publication in the Federal Register.

What it means for your business.

Most closely held companies keep their own share register and will not feel this directly. It matters if your company uses a registered transfer agent, if you are preparing for an offering or a liquidity event that will require one, or if you have considered issuing or tracking equity on a blockchain based platform. The Commission is signaling how it intends to treat that technology, which affects what is realistic for your cap table in the next few years. If any of that describes your plans, ask your attorney to summarize the proposal for you once the full text is published.
