UNITED STATES DISTRICT COURT

FOR THE DISTRICT OF COLUMBIA

TENARIS S.A. and TALTA-TRADING E 

MARKETING SOCIEDADE 

UNIPESSOAL LDA,

Petitioners,

v. 

BOLIVARIAN REPUBLIC OF 

VENEZUELA,

 Respondent.

Case No. 18-cv-1371 (CRC)

MEMORANDUM OPINION

On June 17, 2020, the Court issued a Memorandum Opinion and Order confirming a 

foreign arbitral award in Petitioners’ favor but deferred issuing a final judgment. Because the 

amount of the award needed to be updated to reflect the post-award interest that has accrued 

since the award was issued on January 29, 2020, the Court solicited supplemental submissions

from the parties. 

Petitioners submitted a response detailing their calculations of the award. Venezuela also 

filed a response, contesting only that the post-award interest should be calculated until June 17, 

2020, the date of the Court’s Order confirming the foreign arbitral award, as opposed to the date 

of this Order confirming the exact amount of the award. Venezuela’s contention, though 

mistaken, is understandable. In its June 17, 2020 Memorandum Opinion, the Court erroneously 

stated that “§ 1961’s rate shall apply to the accumulation of interest from the date of this ruling.” 

The Court regrets the oversight. The June 17, 2020 Order was not a final judgment because it 

did not “end[] the litigation on the merits and leave[] nothing for the court to do but execute the 
2

judgment,” Franklin v. D.C., 163 F.3d 625, 628 (D.C. Cir. 1998) (quoting Catlin v. United 

States, 324 U.S. 229, 233 (1945)); rather, the Order expressly indicated that the Court still 

needed to calculate the total amount of the judgment. In actions seeking damages, “a final 

judgment in a Petitioner’s favor declares not only liability but also the consequences of 

liability—what, if anything, [Venezuela] must do as a result.” Id. Although the June 17, 2020

Order “established [Venezuela’s] liability, . . . it granted no relief, it imposed no obligations on 

[Venezuela], [and] it did not say, as final decisions in such cases must, ‘who is entitled to what 

from whom.’” Id. (quoting Horn v. Transcon Lines, Inc., 898 F.2d 589, 591 (7th Cir. 1990)). 

Accordingly, the Order and Judgment accompanying this Memorandum Opinion is the 

applicable final judgment and the Court will calculate post-award interest as running through 

today’s date.

Turning to the amount of the final judgment, the Court finds that Petitioners are entitled 

to the following as awarded by the arbitral tribunal: damages in the amount of $87,300,000 USD;

pre-award interest from April 30, 2008 to January 29, 2016 in the amount of $85,501,213.70 

USD; and costs in the amount of $225,000. Furthermore, the Court finds that Petitioner is 

entitled to post-award interest in the amount of $83,348,795.42 USD.

 In total, then, Petitioners 

 

1 Pursuant to the arbitral award, post-award interest accrues at a rate of 9% per annum 

compounded semiannually, from the date of the Award (January 29, 2016) to the date of the 

judgment (July 17, 2020). Because the post-award interest was last compounded on January 29, 

2020, the Court calculated the amount of additional post-award interest that accrued between 

January 29, 2020 and the date of this award, July 17, 2020. It did so using the following 

formula: additional post award interest = (nominal interest rate)*(compounding period as a 

fraction of a year)*(balance at the beginning of the compounding period). Here, because July 17, 

2020 is 170 days after January 29, 2020, that calculation was: (.09)*(170/365)*(246,060,684.54), 

which equals $10,314,324.58. Adding that amount to the post-award interest that had accrued 

prior to January 29, 2020—which was $73,034,470.84—the Court arrived at the total post-award 

interest of $83,348,795.42.
3

are presently entitled to a judgment in the amount of $256,375,009.12. As noted in the Court’s 

prior ruling, Petitioners are also entitled to post-judgment interest starting from the date of this 

judgment pursuant to 28 U.S.C. § 1961.

A separate Order and Judgment shall accompany this Memorandum Opinion.
