RE: Brad Ainslie et al v. Cantor Fitzgerald LP,

 Civil Action No. 9436-VCZ

Dear Counsel:

I write to address plaintiffs Brad Ainslie, Jason Boyer, Christophe Cornaire, 

John Kirley, Angelina Kwan, and Remy Servant’s (collectively, “Plaintiffs”) 

Motion for Entry of an Order and Final Judgment, on which the parties have joined 

issue on the prejudgment interest to be awarded to Plaintiffs in this matter.1 In 

particular, the parties dispute whether prejudgment interest should be compound or 

simple, and whether prejudgment interest should accrue throughout the full 

pendency of this litigation or if limited tolling is warranted. I write for the parties, 

and refer anyone seeking background on this matter to my January 4, 2023 opinion 

on the parties’ cross-motions for summary judgment.2

Plaintiffs seek interest compounded quarterly; defendant Cantor Fitzgerald 

LP seeks simple interest. Plaintiffs seek interest since the day of Defendant’s 

breach; Defendant seeks an equitable pause for periods during which Plaintiffs 

failed to advance this matter. 

Legal interest is available as of right, and the rate is fixed by statute.

3

 “In 

the absence of an express contract rate, Delaware courts use the ‘legal rate’ as the 

default rate.”

4

 But the Court maintains the discretion to adjust the rate, to award 

compound or simple interest, and to reduce the amount recoverable as equity 

requires, including due to a plaintiff’s delay.5 

The Superior Court disfavors compound interest absent special

circumstances; in keeping with that preference, this Court awards simple interest 

when the claim is a legal claim that could be brought in our sister court of law.6

More broadly, this Court endeavors to award interest that will “compensate 

plaintiffs for losses suffered from the inability to use the money awarded during 

the time it was not available,”7and to “require the respondent to disgorge any 

[improper] benefit it received.”8

I begin with the observation that this is a breach of contract case seeking 

damages and declaratory judgments, all of which are available in the Superior 

Court where simple interest is the norm. That this Court has statutory subject 

matter jurisdiction due to the type of contract at issue, a Delaware partnership 

agreement, does not make Plaintiffs’ loss suffered or the benefit improperly 

enjoyed by Defendant any greater.9 Simple interest is adequate here. 

From there, I consider Defendant’s request to reduce the amount of interest 

because of Plaintiffs’ delay in prosecuting this action. “[T]his Court has the 

Gottlieb, 2000 WL 1005954, at *29 (Del. Ch. July 13, 2000) (explaining that the 

statutory rate should apply to legal claims); Gottlieb, 2000 WL 1005954, at *29 (“As a 

general matter, it makes sense for the Court of Chancery to apply the statutory rate where 

the damage case before it is identical to a claim that could have been brought in Superior 

Court were there no need for this court to decide other equitable issues.”).

discretion to reduce prejudgment interest for ‘delay that is the fault’ or 

‘responsibility’ of a plaintiff or his attorney, [which] reduction is typically reserved 

for situations involving ‘inordinate’ or deliberate delay.”10 

Plaintiffs or their counsel are at fault for inordinate delay in this matter, 

which was filed more than nine years ago. In particular, I attribute the following 

periods of inordinate delay to Plaintiffs or their counsel: (i) from the deposition of 

Defendant’s Head of Partnership on July 12, 2017,

11 to Plaintiffs’ service of new 

discovery requests on April 27, 2018,

12 and (ii) from Defendant’s response to a 

deposition notice on May 28, 2019, to the parties’ response to a status update from 

the Court on August 10, 2020.

13

 While Plaintiffs seek to excuse these delays based 

on their counsel’s filing for bankruptcy and efforts to retain new counsel, those 

problems remain at Plaintiffs’ feet. Interest shall be tolled during these periods.

Defendant also asks that interest be reduced for the following delays: (i)

from Defendant filing its answer on May 12, 2014,

14 to Plaintiffs serving discovery 

requests on September 9, 2014,

15 and (ii) from the entry of a consolidation order on 

June 10, 2016,

16 to Plaintiffs filing a consolidated complaint on October 4, 2016.17

 

While not reflective of a diligent approach to this litigation, these delays are not 

inordinate. Finally, Defendant points to 176 days in which “the parties chose to 

pause discovery . . . while discussing the possibility of settlement.”

18

 This delay is 

not solely attributable to Plaintiffs or their counsel. Interest shall not be tolled 

during these periods.

I ask counsel to confer with their calculators and submit a stipulated 

proposed order. IT IS SO ORDERED. 

Sincerely,

/s/ Morgan T. Zurn
