APPENDIX

This appendix includes the prejudgment interest multipliers calculated by the Court for the 

associated plaintiffs and a table specifying each plaintiffs’ award before and after the addition of 

prejudgment interest. 

As it did previously in Cabrera v. Islamic Republic of Iran, Civ. A. No. 18-2065 (JDB), 

2022 WL 2817730 (D.D.C. July 19, 2022), the Court will use the Federal Reserve’s data for the 

average annual prime rate in each year from the date of the respective attacks through 2023.1 Using

the prime rates for the years from the date of the attack, and discounting for the percentage of the 

year elapsed at the time of each attack, yields the following multipliers:2

Associated Direct Victims Attack Date Multiplier

Benton, Bogar, Brostrom, Garcia, Hovater, 

Rainey, Zwilling

July 13, 2008 1.736093

Roush August 16, 2009 1.662423

Caron April 11, 2010 1.628083

Benson, Campbell, Nichols, Pittman, Ratzlaff, 

Robinson, Spehar, Strange, Vaughn, Vickers 

August 6, 2011 1.560786

Darrough, Newman October 29, 2011 1.549263

Hunter May 31, 2012 1.520481

Ellis June 18, 2013 1.470380

Zimmerman July 15, 2013 1.466906

Baldridge, Bays June 10, 2017 1.286767

Applying those multipliers, the Court concludes that plaintiffs are entitled to the following 

amounts as compensatory damages (solatium or pain-and-suffering damages, plus prejudgment 

interest):

Plaintiff Pain and Suffering or 

Solatium Damages

Compensatory Damages Plus 

Prejudgment Interest

Jonathan Richard Colton Benton $8,000,000 $13,888,747.50

Elizabeth Lindsey Benton $4,000,000 $6,944,373.75

S.J.B. $2,500,000 $4,340,233.59

G.S.B. $2,500,000 $4,340,233.59

H.S.B. $2,500,000 $4,340,233.59

Carlene Renee Cross $5,000,000 $8,680,467.19

Michael Dean Bogar $5,000,000 $8,680,467.19

2 Specifically, the Court calculated these multipliers—using SSG Benton as an example—as follows. First, 

the Court multiplied $1.00 by the prime rate in 2008 (5.09%); discounted that amount to reflect that only 46.72% of 

the year remained after July 13, 2008; and added that amount to $1.00, for a result of $1.02378. The Court then took 

that amount and multiplied it by the prime rate in 2009 (3.25%) and combined that amount with $1.02378, for a result 

of $1.057054. The Court continued this iterative process through May 16, 2023, resulting in a total multiplier of 

1.736093. Because the attacks relevant to the associated plaintiffs were committed on ten different dates, the Court 

repeated this process for each attack date. To approximate the 2023 prime rate, the Court averaged the prime rates for 

the past six years—approximately 4.32%—and again discounted the interest to reflect that only a portion of the year 

has elapsed as of May 16, 2023. See Cabrera, 2022 WL 2817730, at *55 n.46 (applying same methodology).
