SIH PARTNERS LLLP, EXPLORER PARTNER CORP., TAX MATTERS PARTNER, Petitioner

v.

COMMISSIONER OF INTERNAL REVENUE, Respondent

—————

Docket No. 10099-20. Filed August 6, 2026.

—————

The TMP of partnership S timely petitioned this Court challenging R’s adjustments in a Notice of Final Partnership Administrative Adjustment regarding qualified dividend income (QDI), reclassified as ordinary dividend income, and corresponding foreign tax credits (FTC). R principally contends that investment positions held by S are substantially similar or related property as defined by I.R.C. § 246(c)(4) and accompanying Treasury regulations.

Held: The Substantial Overlap Test in Treas. Reg. § 1.246-5(c)(1)(iii) has not been met; however, the Anti- Abuse Rule of Treas. Reg. § 1.246-5(c)(1)(vi) is applicable, and therefore S is not entitled to QDI treatment under I.R.C. §§ 1(h)(11)(B)(iii)(I) and 246(c).

Held, further, S has not satisfied all statutory requirements to qualify for the FTC.

Nathan P. Wacker, Rajiv Madan, Nathaniel J. Dorfman, Christopher P. Bowers, Erin E. Girbach, and Nadiya F. Beckwith-Stanley, for petitioner.

Brandon S. Cline, Christopher A. Pavilonis, Thomas J. Kerrigan, Naseem Jehan Khan, and Michael E. Washburn, for respondent.

WEILER, Judge: On December 5, 2019, the Internal Revenue Service (IRS) issued a Notice of Final Partnership Administrative Adjustment (FPAA) for the tax year ending December 31, 2012 (tax year at issue), to Explorer Partner Corp., the tax matters partner for SIH Partners, LLLP (SIHP). In the FPAA respondent (i) reduced SIHP’s qualified dividend income (QDI) by $170,764,863; (ii) reclassified the reported QDI of $170,764,863 as ordinary dividend income; and (iii) reduced SIHP’s foreign tax credit by $25,614,729 on the basis of section 246(c)(4) 1 and accompanying Treasury regulations.

The two issues for decision are whether (1) SIHP’s $170,764,863 of QDI should be reclassified as ordinary dividend income and (2) SIHP’s foreign tax credit should be reduced by $25,614,729.

FINDINGS OF FACT

Some of the facts are stipulated and are so found. The Stipulation of Facts and the attached Exhibits are incorporated herein by this reference.

I. SIHP

SIHP, the partnership at issue in the case, is a limited liability partnership organized under the laws of the State of Delaware on April 2, 2007, and classified as a partnership under the Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA), 2 Pub. L. No. 97-248, §§ 401–407, 96

1 Unless otherwise indicated, statutory references are to the Internal Revenue

Code, Title 26 U.S.C. (I.R.C. or Code), in effect at all relevant times, regulation references are to the Code of Federal Regulations, Title 26 (Treas. Reg.), in effect at all relevant times, and Rule references are to the Tax Court Rules of Practice and Procedure. All monetary amounts are rounded to the nearest dollar. 2 Before its repeal TEFRA governed the tax treatment and audit proceedings

for many partnerships, including SIHP. 3

Stat. 324, 648–71. SIHP had its principal place of business in Delaware when the Petition was timely filed.

SIHP wholly owns Susquehanna International Holdings, LLC (SIH), a limited liability company organized under the laws of the State of Delaware. SIH in turn owns CVI Holdings LLC (CVIH), also a limited liability company organized under the laws of the State of Delaware. CVIH wholly owns Capital Ventures International (CVI), an unlimited liability company with share capital organized under the laws of the Cayman Islands. For U.S. federal income tax purposes, SIH, CVIH, and CVI were disregarded entities of SIHP with all items of income, gain, loss, deduction, and credit reported by SIHP.

During the tax year at issue SIHP had six partners: petitioner, Colombus International Holdings, Inc., Cortes International Holdings, Inc., Coronado International Holdings, Inc., Lasalle International Holdings, Inc., and Balboa International Holdings, Inc. Petitioner’s shareholders during the tax year at issue were Jeffrey Yass, Arthur Dantchik, Eric Brooks, and Joel Greenberg.

II. SIG

SIHP, SIH, CVIH, and CVI are affiliated with Susquehanna International Group, LLP (SIG). SIG is a privately held global trading firm, founded in 1987, and it is an active participant in the options and futures market in over 50 stock and options exchanges. SIG’s core business is to act as a liquidity provider in financial markets, such as the NYSE and NASDAQ, as a “market maker” where it provides two- sided markets—a bid price and an offer price—on a continuous basis to ensure a fair, efficient, and liquid market.

SIG engages in millions of trades around the world each business day. SIG trades and makes proprietary investments in equities, fixed income, energy, commodity, index, derivative products, private equity, and venture capital, research, customer trading, and institutional sales. SIG has a work force of approximately 3,300 employees who are employed through entities under its management that are registered as broker-dealers with the U.S. Securities and Exchange Commission. Like other market makers, when SIG buys or sells a particular option it typically also acquires an offsetting position to hedge 3 any risk. This

3 Typically, a “hedge” is two investments that offset the specific risks of each

other. For example, long and short positions of similar value in S&P 500 index (SPX) and SPY, respectively, would be a typical hedge. 4

hedging allows SIG to be financially indifferent as to whether the values of the options being traded increase or decrease in price. Because market makers like SIG are hedged in this way, they do not earn a profit through hedge trading. Rather, SIG makes a return from its bid-ask spread, which is the fractional difference (often pennies or less) between their offered bid price and their offered ask price. 4 This small margin, however, correlates to the minimal risk involved, a key factor for SIG’s interest as market makers avoid taking on potential risks with respect to the positions they choose to trade in.

SIG maintains longstanding, unhedged short positions 5 in one or more indexes or securities to mitigate risk in the event of an economic downturn (Firm Hedge). The Firm Hedge has existed in some form and amount continuously since 1987 and has lost approximately $1.25 to $2.5 billion. In 2012 the Firm Hedge 6 consisted of three indexes: an index fund and two exchange-traded funds (ETFs) 7 which included the SPX, the IWM, and the FXI. 8

SIG often transferred ownership of the Firm Hedge among its affiliates. Ultimately, the location of the Firm Hedge, i.e., which entity holds the rights at what time, is irrelevant as the overall financial impact remains the same because of the structure of the firm. Moreover,

4 A “bid price” is the highest price that a buyer is willing to pay for an option,

while an “ask price” is the lowest price that a seller is willing to accept. 5 Maintaining a short position in stocks is essentially the practice of selling

borrowed shares of stocks, called equities, anticipating that the stocks’ prices will decline, and the same numbers of borrowed shares can be repurchased at lower prices. 6 The Firm Hedge is not hedging against any specific investment. Instead, it

mitigates firm risk in the event of an economic downturn by betting against the market. 7 The S&P 500 is a stock market index which tracks the performances of 500

of the largest publicly traded U.S. companies. It serves as a key indicator of the U.S. stock market and economy, similar to the Russell 2000 ETF (IWM) and the China Large Cap ETF (FXI).
