United States Tax Court
164 T.C. No. 9
FACEBOOK, INC. & SUBSIDIARIES,
Petitioner
v.
COMMISSIONER OF INTERNAL REVENUE,
Respondent
—————
Filed May 22, 2025.

Docket No. 21959-16. 1
—————

On September 15, 2010, P entered into a cost
sharing arrangement (CSA) under Temp. Treas. Reg.
§ 1.482-7T with S, its Irish subsidiary. The CSA required P
and S to engage in a platform contribution transaction
(PCT), compensating each other for the value of any
“platform contributions” made. See Temp. Treas. Reg.
§ 1.482-7T(a)(2), (b)(1)(ii), (c)(1). Pursuant to the PCT, P
and S granted each other the right to use any existing
online platform technology in their respective territories:
the United States and Canada for P and the rest of the
world (ROW territory) for S. In a separate agreement, P
granted S all rights relating to P’s existing users,
advertisers, and third-party application developers in the
ROW territory, including their data. P also granted S the
right to use its marketing intangibles in the ROW territory.
S made payments to P for 2010 on the basis of P’s valuation
of these agreements at a September 2010 net present value
(NPV) of $6.3 billion.
In addition to a PCT payment to compensate P for
its upfront PCT contributions, S also was required by the
regulations to make (and commit to making annually) cost

and 2013 are at issue.

sharing transaction (CST) payments to compensate P for
ongoing intangible development costs (IDCs) in proportion
to its share of reasonably anticipated benefits (RAB share)
from exploiting cost shared intangibles. See id. para.
(b)(1)(i). S made a CST payment for 2010.
R’s valuation expert selected the income method as
the best method for valuing contributions to the CSA, see
id. para. (g)(4), and opined that the NPV of the assets P
contributed to the CSA was $19.945 billion. Because this
valuation increased S’s required PCT payment, R made a
PCT allocation for 2010. R also increased S’s RAB share
used to determine S’s CST payment for 2010.
P contends that the income method cannot apply
because both P and S made “nonroutine platform
contributions.” See id. subdiv. (i)(D). P also argues that R
selected the wrong values for three key inputs to the
income method: revenue projections for the ROW territory,
the appropriate discount rate for those projected revenues,
and S’s best realistic alternative to cost sharing. P argues
that once those inputs are corrected, R’s income method
produces a result consistent with P’s valuation. See Treas.
Reg. § 1.482-1(e). P simultaneously maintains that the
income method cannot be the best method because it
cannot produce an arm’s-length result and that the
regulations are invalid because they limit the expected
return on IDCs to a discount rate reflecting marketcorrelated risks. P also challenges R’s adjustments to P’s
and S’s RAB shares.
1. Held: Only one CSA participant—P—made a
nonroutine platform contribution and therefore the income
method in Temp. Treas. Reg. § 1.482-7T(g)(4) can apply.
2. Held, further, R implemented the income method
unreasonably, by selecting the wrong inputs, and therefore
abused his discretion under I.R.C. § 482 by reallocating
income to P with respect to the PCT payment to the extent
of the wrong inputs.

3
3. Held, further, with reliable inputs, the income method
is the best method and produces an arm’s-length PCT
payment value.
4. Held, further, Temp. Treas. Reg. § 1.482-7T reasonably
implements I.R.C. § 482 and is not invalid.
5. Held, further, Temp. Treas. Reg. § 1.482-7T(i)(6) does
not operate as a safe harbor and therefore does not
preclude R from making a PCT allocation under paragraph
(i)(3).
6. Held, further, R did not abuse his discretion under
I.R.C. § 482 by adjusting P’s and S’s RAB shares to
determine the required CST payment.
7. Held, further, R’s method for calculating RAB shares is
consistent with Temp. Treas. Reg. § 1.482-7T and provides
the most reliable estimate of reasonably anticipated
benefits, using corrected inputs.

PUGH, Judge: The Internal Revenue Service (IRS or respondent)
determined a deficiency in petitioner’s federal income tax for 2010 in a
Notice of Deficiency dated July 26, 2016 (Notice). This deficiency arose
because respondent reallocated income between petitioner’s domestic
and foreign affiliates under section 482 2 in connection with
intercompany agreements they entered into, effective September 15,
2 Unless otherwise indicated, statutory references are to the Internal Revenue
Code, Title 26 U.S.C., 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. We round
monetary amounts and percentages as appropriate.

2010 (transaction date). 3 Effective that date, Facebook, Inc. (Facebook
US), 4 entered into a cost sharing arrangement (CSA) and two related
license agreements with its Irish subsidiary, Facebook Ireland Holdings
Unlimited (FIH). 5 We refer to FIH and its wholly owned Irish
subsidiary, Facebook Ireland Limited (FIL), together as “Facebook
Ireland.” We refer to Facebook, Inc., and subsidiaries together as
Facebook or petitioner, and the CSA and associated licenses as the
“transaction.” Petitioner timely challenged respondent’s determination.
We begin, as we always must, with the statute. Section 482 in
effect for 2010 provides in full:
In any case of two or more organizations, trades, or
businesses (whether or not incorporated, whether or not
organized in the United States, and whether or not
affiliated) owned or controlled directly or indirectly by the
same interests, the Secretary may distribute, apportion, or
allocate gross income, deductions, credits, or allowances
between or among such organizations, trades, or
businesses, if he determines that such distribution,
apportionment, or allocation is necessary in order to
prevent evasion of taxes or clearly to reflect the income of
any of such organizations, trades, or businesses. In the case
of any transfer (or license) of intangible property (within
the meaning of section 936(h)(3)(B)), the income with
respect to such transfer or license shall be commensurate
with the income attributable to the intangible.
The regulations promulgated under section 482 authorize
commonly controlled entities to enter into a CSA. 6 Facebook US and
Facebook Ireland entered into the CSA pursuant to the cost sharing
regulations in effect for 2010. See Temp. Treas. Reg. § 1.482-7T. We refer

3 Because of the number of defined terms and acronyms we must use, we have

included in Appendix B a glossary to aid the reader.

4 Facebook US originally was incorporated under the name “TheFacebook, Inc.”
It later changed its name to “Meta Platforms, Inc.” We use “Facebook” to refer to the
worldwide affiliated group, to be consistent with the trial record.
5 The CSA was executed on November 12, 2010.
6 The regulations under section 482 commonly are referred to as the “transfer
pricing regulations.” Section -7 of the transfer pricing regulations commonly is referred
to as the “cost sharing regulations.”

10
to these regulations as the “2009 cost sharing regulations.” 7 This is the
first time we apply them. 8
In a CSA, controlled (i.e., related) participants commit to bear the
ongoing costs of developing certain intangibles in proportion to their
respective shares of reasonably anticipated benefits from exploiting
those cost shared intangibles (RAB shares). Temp. Treas. Reg. § 1.4827T(a)(1), (b)(1)(i). By bearing its RAB share of the ongoing intangible
development costs (IDCs) going forward, a controlled participant in a
CSA comes to own, in its designated territory, the “cost shared
intangibles” that it helps develop through that shared funding. Id. para.
(b)(1)(iii), (4)(i). In addition to the annual “cost sharing transaction”
payments (CST Payments) during the CSA, controlled participants
must compensate each other for the value of any upfront noncash
contributions in proportion to their RAB shares. Id. paras. (a)(2),
(b)(1)(ii). The 2009 cost sharing regulations label the upfront transaction
in which CSA participants make contributions a “platform contribution
transaction” (PCT), the noncash contribution a “platform contribution,”
and the payment for the upfront noncash contribution a “PCT Payment.”
See id. paras. (a)(2), (b)(1)(ii), (c)(1).
In the CSA, Facebook US and Facebook Ireland agreed to
codevelop future versions of the hardware and software systems
underlying Facebook’s Online Platform (FOP technology). 9 They divided

The 2009 cost sharing regulations were effective January 5, 2009, as
temporary regulations. See T.D. 9441, 74 Fed. Reg. 340 (Jan. 5, 2009), 2009-7 I.R.B.
460. Initially proposed in 2005, see Prop. Treas. Reg. § 1.482-7, 70 Fed. Reg. 51,116
(Aug. 29, 2005), they were made final effective December 16, 2011, see T.D. 9568, 76
Fed. Reg. 80,082 (Dec. 22, 2011), 2012-12 I.R.B. 499.
7

8 The 2009 cost sharing regulations replaced the 1995 cost sharing regulations

and redesignated them Treasury Regulation § 1.482-7A (Treas. Reg.). See 74 Fed. Reg.
352. The 1995 cost sharing regulations were at issue in Amazon.com, Inc. & Subs. v.
Commissioner (Amazon I), 148 T.C. 108 (2017), aff’d, Amazon.com, Inc. & Subs. v.
Commissioner (Amazon II), 934 F.3d 976 (9th Cir. 2019), and Veritas Software Corp.
& Subs. v. Commissioner, 133 T.C. 297 (2009). The 2009 cost sharing regulations
replaced the term “buy-in payment” (in Treas. Reg. § 1.482-7A(g)) used in those cases
with “PCT Payment.”
As in many cases we must use, and take care using, terminology. For
example, the term “platform” has four meanings in this case that we must keep distinct
in our discussion:
9

11
all interests in the cost shared intangibles into two nonoverlapping
geographical territories; the U.S. and Canada (domestic territory) was
assigned to Facebook US, and the rest of the world (ROW territory) was
assigned to Facebook Ireland. See id. para. (b)(1)(iii), (4)(i). Facebook
Ireland also committed to bear its RAB share of IDCs through CST
Payments.
In connection with the CSA, Facebook US and Facebook Ireland
licensed to each other their existing rights in the FOP technology for use
in their respective territories. Additionally, Facebook US licensed to
Facebook Ireland the rights associated with Facebook US’s existing
user, advertiser, and developer relationships (user community rights)
and its marketing intangibles, including trademarks, in the ROW
territory.
The transfer pricing documentation provided that Facebook
Ireland would make contingent annual payments to Facebook US (over
a period of years) for the existing FOP technology, user community
rights, and marketing intangibles that Facebook US contributed to the
CSA. The documentation used the value of Facebook US’s upfront
contributions as the starting point for computing the contingent annual
payments made by Facebook Ireland. The Petition challenges the
adjustment respondent made in the Notice to the total contingent
annual payments Facebook Ireland made for 2010 (calling them gross
royalties). 10

(1) the 2009 cost sharing regulations’ definition of assets contributed to a
CSA—“platform contributions”—that must be compensated through a
PCT, see Temp. Treas. Reg. § 1.482-7T(c)(1);
(2) the technology stack that Facebook operates—the “FOP technology” for
purposes of our analysis—that enables communication by users,
advertising by advertisers, and software application (app) development by
third-party app developers, which was transferred in connection with and
was to be developed further under the CSA;
(3) an economic description of a business—a “platform business”—that
facilitates interactions between or among participants and often exhibits
network effects; and
(4) the product name—“Facebook Platform” (capital P)—for Facebook’s set of
application programing interfaces (APIs) that allows third-party
developers to build apps and offer them to Facebook users.
10 Respondent does not challenge the form of payment (contingent and annual)
adopted in the transfer pricing documentation.

12
The parties use various terms to refer to the value of Facebook
US’s upfront contributions and Facebook Ireland’s contingent annual
payments computed on the basis of that value. Petitioner sometimes
refers to the value of the “PCT and other intangibles” and also “PCT and
royalty.” Respondent often uses the defined term in the regulations,
“PCT Payment.” Consistent with the regulations, we adopt the term
PCT Payment to mean the value of Facebook US’s upfront contributions
to the CSA, which in turn is the value to be used for computing the
amount of the contingent annual payments owed by Facebook Ireland
for 2010 and subsequent years. This PCT Payment value is the main
dispute between the parties that we must resolve. Facebook used an
estimated net present value (NPV) of $6.3 billion. 11 Respondent
contends that the NPV is $19.945 billion.
The parties disagree over the best method for valuing the PCT
Payment under the 2009 cost sharing regulations. See Temp. Treas. Reg.
§ 1.482-7T(g). The parties also disagree over the inputs to be used in
whatever method we adopt. 12 Respondent’s transfer pricing valuation
expert, T. Scott Newlon, 13 selected the income method in paragraph
(g)(4) as the best method. Petitioner argues that the income method is
not appropriate and urges us to adopt an unspecified method under
paragraph (g)(8) offered by its primary valuation expert, Sanjay Unni.
Dr. Unni’s unspecified method is an amalgam of the income method and
a method he derived from cases applying prior regulations. Petitioner
also offers an alternative valuation by another of its valuation experts,
Timothy Reichert, using the residual profit split method (RPSM) in
paragraph (g)(7). Petitioner also contends that Dr. Newlon used the
11 Although petitioner states that the NPV was $6.3 billion, the transfer pricing

documentation did not include a total (it listed a percentage for the marketing
intangibles, not a value). Respondent’s Notice stated that Facebook determined an
NPV of $6.7 billion. We need not resolve this curious discrepancy as the initial
valuation Facebook used does not affect our ultimate holding, but to avoid confusion
we will use the $6.3 billion figure.
12 A third issue involves the interaction between the provisions in the 2009 cost

sharing regulations governing respondent’s adjustments to the value of the PCT
Payment, under Temporary Treasury Regulation § 1.482-7T(i)(3) (Temp. Treas. Reg.),
and the rules governing periodic adjustments that respondent adopted to implement
the commensurate with income standard of section 482, in paragraph (i)(6). Petitioner
argues that these rules provide an implicit safe harbor protecting it from respondent’s
proposed adjustments under paragraph (i)(3).
13 Appendix A to this Opinion includes thumbnail sketches of the experts who
testified in this case. We discuss their testimony only to the extent it is relevant to our
analysis.

13
wrong values for three key inputs needed for the income method (and
Dr. Unni’s unspecified method): revenue projections for the ROW
territory, the appropriate discount rate for those projected revenues, and
Facebook Ireland’s best realistic alternative to cost sharing. These are
the key factual disputes we must resolve. At the same time, petitioner
argues that the income method and the other methods specified in the
2009 cost sharing regulations are invalid insofar as they mandate
valuation methods that do not produce an arm’s-length result. We take
up petitioner’s three challenges (to Dr. Newlon’s method, Dr. Newlon’s
key inputs, and the regulations themselves) in turn.
The parties also disagree over how to estimate Facebook Ireland’s
RAB shares for purposes of computing its CST Payments. Petitioner
reported an RAB share of 44% for Facebook Ireland for 2010; 14
respondent contends that it should be 53.5%. We therefore must
determine how to estimate Facebook Ireland’s RAB shares as well.
In deciding these issues, our focus is on what was reasonably
anticipated as of the transaction date. Unless otherwise specified, the
facts we find are as of the transaction date. To put the valuation inputs
used by the experts into context and to evaluate their reliability we will
go back further in time. We do not need to dwell on Facebook’s origins.
But we do need to understand its business model, products, and
international growth leading up to the transaction.
FINDINGS OF FACT
Some of the facts have been stipulated and are so found. Facebook
US is the U.S. parent of a group of affiliated corporations that joined in
the filing of a consolidated federal income tax return for 2010.
Incorporated in Delaware in 2004, Facebook US maintains its principal
place of business in Menlo Park, California. 15 Facebook operates an
online social networking platform and makes money primarily by selling
advertisements shown to its users. 16
14 For simplicity we use the RAB share identified in petitioner’s posttrial brief
but note that the Petition stated that the percentage reported was 43%.
15 Absent stipulation to the contrary, this case is appealable to the U.S. Court

of Appeals for the Ninth Circuit. See § 7482(b)(1)(B).

16 The Court issued protective orders adopting procedures to protect certain
confidential information, including trade secrets and proprietary technology, during
the pretrial, trial, and posttrial phases of this case. We have determined that the facts

14
As of the transaction date, Facebook was a privately held, venture
capital (VC)-backed company. It received funding by issuing stock to
private investors in financing rounds that took place in 2004, 2005,
2007, and 2009. It completed an initial public offering (IPO) of its
common stock in May 2012. Before the IPO, its stock could be traded on
secondary markets only.
Facebook formed its first international entity, an advertising
sales office, in the United Kingdom in August 2007. This was its only
foreign subsidiary as of June 2008 when it started considering locations
for its international headquarters. In October 2008 Facebook announced
that it planned to open its international headquarters in Dublin,
Ireland. Among other reasons—including access to a talented labor force
and proximity to markets it wanted to develop—it chose Ireland to help
reduce its global effective tax rate.
FIL was incorporated as an Irish corporation resident in Ireland
in October 2008. FIH was incorporated as an Irish corporation with a
registered address in Ireland and its stated place of management and
control in the Cayman Islands in January 2009. FIH was a holding
company and did not have any employees. As noted above, we refer to
FIH and FIL together as Facebook Ireland. Both were wholly owned
subsidiaries of Facebook US, with FIH wholly owning FIL. Facebook
first capitalized FIH with a $10 million contribution in August 2009,
made an additional contribution of nearly $4 million later in 2009, and
another, of $20 million, in August 2010. Effective September 1, 2010,
FIL elected to be treated as a disregarded entity for U.S. federal income
tax purposes pursuant to Treas. Reg. § 301.7701-3, after which it no
longer was a separate entity for U.S. federal income tax purposes.
In December 2009 Facebook US and Facebook Ireland executed a
series of intercompany agreements (2009 Agreements), in which
Facebook Ireland obligated itself to perform certain functions, and
certain market development expenses were allocated to it by Facebook
US.
Although Facebook Ireland had nearly 200 employees by the
transaction date, it lacked the financial and accounting systems
necessary to record third-party revenue before September 1, 2010.
Facebook US therefore booked all revenue before the transaction.
we find in this Opinion do not constitute confidential information warranting
protection.

15
Facebook Ireland did not record any intangible property leading up to
the transaction; it recorded only cash and intercompany receivables.
Facebook Ireland established the necessary financial and
accounting systems on September 1, 2010 (the day FIL elected
disregarded entity status), that allowed it to begin recording revenue.
Two weeks later, in connection with the CSA, the ROW territory became
Facebook Ireland’s territory and Facebook Ireland began funding its
RAB share of the IDCs.
The main factual disagreements between the parties relate to
their valuation experts’ choices of valuation methods and key valuation
inputs. To evaluate Facebook’s revenue projections, we need to
understand its idiosyncratic business opportunities and risks. To select
an appropriate discount rate for those projected revenues, we need to
consider the market-correlated risks for similar companies. And to
determine Facebook Ireland’s best realistic alternative to cost sharing,
we need to understand the role of Facebook’s ad sales team and compare
it to the third-party ad resellers (Resellers) and advertising agencies
used by the valuation experts as comparables. Finally, Facebook’s preCSA international activities and the 2009 Agreements are relevant to
the parties’ dispute over what each controlled participant brought to the
CSA, which in turn dictates which valuation method is appropriate and
how it applies.

Facebook’s social networking platform

Facebook’s stated mission is 17 to “[g]ive people the power to share
and make the world more open and connected.” Its technology enables
individuals to create a user profile (Profile), through which they can
share information, establish connections with other users (friends), 18
communicate with those users, and view and post content. It also
enables businesses and other organizations to create public profiles
(Pages). Its third-party developer platform, Facebook Platform, allows
developers to integrate their apps into the site and interact with users.
We generally use the present tense for factual descriptions that are not
specific to a time period and the past tense for facts that are specific to a particular
period; however, our findings are as of the transaction date unless we otherwise
specify.
17

18 It has become common to use the noun “friend” as a verb, abandoning the
previously useful verb “befriend”; thus at trial witnesses referred to befriending
someone on Facebook as “friending.”

16
Facebook collects data on its users. It collects demographic data
(age, gender, location, interests, etc.) as well as contextual data (how
users interact with content on its site). Facebook’s goal in collecting this
data is to map digitally the “social graph.” The social graph is a
conceptual representation of the real-world connections between people
and their friends and interests. Facebook uses this data in developing
and improving products, and targeting ads for users.
Facebook’s business strategy is first to grow, retain, and engage
users on its site and then to monetize them (that is, earn revenue).
Facebook measures its success in each part of this strategy with
different metrics. For user growth and engagement, it generally uses
monthly active users (MAUs) and daily active users (DAUs). 19 To
measure its ability to monetize the users, it uses average revenue per
user (ARPU).
Facebook operates a platform business because it facilitates
interactions between, and among, users, advertisers, and app
developers. Platform businesses often exhibit network effects. Network
effects are positive when the value of the platform to one user is
enhanced by the presence of other users of the platform. Positive
network effects can accelerate the growth of a platform. Negative
network effects can accelerate the decline of a platform.
Facebook was exhibiting positive network effects as of the
transaction date. These positive network effects provided a “tailwind”
for user growth and gave Facebook a competitive advantage. Facebook’s
positive network effects did not insulate it from competition, however,
because users could switch to another platform or use multiple
platforms at once. We now turn to a description of the platform business
and participants, along with the tailwinds, then address the perceived
headwinds (the market risks and challenges) as of the transaction date.
A.

Users

Leading up to the transaction date, Facebook was succeeding on
the first part of its business strategy, growing an engaged user
community. Users grew rapidly after Mark Zuckerberg launched
19 MAUs reflect the number of people who have logged in and visited the
Facebook site, or have taken an action to share content or activities with their
connections through integrated third-party websites in the last 30 days of the date of
measurement. DAUs are measured the same way as MAUs but look to activity in the
last 24 hours of the date of measurement.

Facebook in February 2004. Initially restricted to students at a few
colleges, by the end of 2006 registration was open to anyone with a valid
email address who was at least 13 years old. By the transaction date,
Facebook had over 500 million global MAUs. Approximately 384 million
MAUs were located outside the United States and Canada (growing
from 94 million in January 2009).
1.

Product development

Facebook’s user growth reflects the popularity of its core user
products, launched early in its history. Profile, launched in 2004,
enables users to create an online identity. Photos, launched in 2005,
allows users to upload and share photos and to “tag” the people shown
in them. News Feed, launched in 2006, is the user “landing page” and
displays content including user stories, photos, videos, and status
updates from friends, groups, and followed Pages.
Facebook’s products are developed, maintained, and improved by
its software engineers, often using user data to inform their work. In
addition to observing user behavior as they develop products, Facebook’s
engineers sometimes build products that solicit user input. For example,
in late 2007 and early 2008, Facebook translated the site’s user interface
elements into different languages. Facebook’s engineers accomplished
this by developing a translation tool that used crowdsourced responses
about how to translate. Through this translation tool, users could
submit translations of words from Facebook’s user interface into other
languages and rank (vote on) translations submitted by other users.
Like any consumer data, Facebook’s user data can be used to
identify problems and opportunities, but in isolation does not provide
technical solutions or designs for a new or improved product. User data
are inputs Facebook uses to build products and make decisions.
2.

User growth

Facebook understood that two of its biggest levers for user growth
were its scalable products and network of users. Facebook aimed for its
user products to be “scalable” (that is, expand automatically to fit
demand as demand grows). Its site was, for the most part, a uniform
global product that could scale anywhere it was not blocked. Facebook
also understood the importance of “product-market fit” (i.e., having a
product that people find valuable and want to continue using). From
2008 through 2010, a cross-functional group of employees, the “Growth
Team,” focused on building a scalable product to grow users.

18
One product that the Growth Team used to grow users was People
You May Know (PYMK). PYMK recommended potential new friends to
Facebook users. It relied on user data, including the user’s existing
friends, demographic data, and prior interactions with PYMK. Facebook
saw PYMK as its number one lever for growth. “Contact importer”
technology enabled users to transfer their contacts from email and
instant messaging services into their Facebook accounts, which PYMK
then used to recommend other users to “friend.”
Facebook also used scalable technologies (e.g., Groups, Pages, and
Facebook Platform) to provide content to users specific to their location.
Through these technologies, users could create groups for local events,
local businesses and organizations could communicate with users, and
developers could create apps that appealed to local users. Many users’
friends were local, and their News Feed content was inherently local
because it was personalized to them. This product-driven “scalable
localization” was more cost efficient than nonscalable “custom
localization.” In a few markets (such as Japan) Facebook needed, and
devoted resources including local employees to provide, a more localized
approach.
3.

User operations and privacy

As the number of users grew, so too did the need for a user
operations team that could moderate the content users posted and
provide technical support. As Facebook collected user data, the need for,
and importance of, a data controller that could comply with any countryand region-specific regulations also grew. So too did the need to address
data privacy concerns.
B.

Monetization

Leading up to the transaction date, Facebook also made strides
on the second part of its business strategy: monetization. Facebook
monetized its users primarily by displaying targeted ads to them on its
site. It also generated non-ad revenue by charging a fee when users
redeemed its virtual currency, Facebook Credits (Credits), on an app
using the Facebook Platform. In 2010 Facebook generated 95% of its
revenue (approximately $1.9 billion) from selling online digital
advertising. 20 Credits accounted for the other 5% of Facebook’s 2010
20 By contrast, offline, or traditional, advertising includes print (newspaper,
direct mail, magazines), broadcast (television, radio), and outdoor (billboards).

19
revenue. We go through Facebook’s ad sales team functions in some
detail for two reasons. First, ad revenue made up the bulk of the
projected revenue that the valuation experts used to value the PCT
Payment. Second, the experts disputed the appropriate comparable for
this function (as Facebook Ireland’s hypothetical “best realistic
alternative”) when applying the income method.
Facebook’s ad sales team was divided into a Direct Sales
Organization (DSO), Inside Sales Organization (ISO), and Online Sales
Operations Organization (OSO). The DSO provided high-touch services
to the largest advertisers. The ISO serviced mid-tier (small- and midsize) business advertisers with a “lighter touch” than the DSO. ISO
representatives generally engaged with clients through emails, phone
calls, and video conferences, with occasional marketing trips to meet in
person. The OSO mainly provided customer support services to
advertisers that used Facebook’s “self-service” ad platform, called Ads
Manager.
1.

Digital advertising

Early on, Facebook’s ad sales team sold ads through insertion
orders (IOs). An IO is a contract, signed by an advertiser and Facebook,
that specifies the details of the advertiser’s campaign. The DSO sold IOs
to large brand advertisers.
Generally, IOs are used for ad “impressions” (the times an ad is
shown to a user), specifying the number to be purchased. To place an IO,
the advertiser typically must spend above a minimum threshold and is
guaranteed the number of ad impressions it purchases. Ad impressions
generally are associated with brand advertising—ads used to promote
awareness of a brand. 21
a.

Ads Manager

In 2007 Facebook launched two products that transformed its
advertising business. One, Facebook Pages, allowed organizations and
businesses to create Profiles and engage with users, who could become
“fans” of their Pages. The other, Ads Manager, was an online platform
that allowed prospective advertisers to purchase and manage ad
campaigns on Facebook without having to interact with a salesperson;
for this reason it also was referred to as the “self-service” ad platform.
21 Digital ads also could be priced on a “cost per click” basis; most of the ads
sold through Ads Manager were priced on that basis.

20
Ads Manager did not require an advertiser to spend a minimum amount
and did not require an IO. It was priced through an online auction
system.
Ads Manager made advertising on Facebook more accessible
globally. Any advertiser anywhere in the world with an internet
connection (where Facebook was not blocked) could use Ads Manager to
run an ad campaign on the site. Advertisers who were managed by
Facebook’s ad sales team could and did use Ads Manager. And
advertisers could run ad campaigns using Ads Manager without ever
interacting with a Facebook salesperson. Ads Manager also made
advertising on Facebook accessible to small and mid-sized businesses
who would not meet the minimum threshold for purchasing ads through
IOs.
Ads Manger made Facebook’s advertising business more efficient.
First, advertisers using Ads Manager required less sales and marketing
support. Before it was launched, a Facebook employee had to
communicate with prospective advertisers about whether they wanted
to run an ad campaign. After it was launched, Facebook could promote
Ads Manager in its own internet-based marketing, including on-site
merchandising (i.e., marketing on its own site), search engine
marketing, search engine optimization (e.g., ensuring Facebook was
listed as a top search result on search engine sites), email marketing,
and paid ads on other websites. And advertisers could use those links to
place ads on their own.
Ads Manager advertisers also generally required less operational
support from Facebook’s ad sales team. Before it was launched, a
Facebook employee had to execute an IO reflecting the terms of an ad
campaign. After it was launched, advertisers could select and adjust the
terms of their ad campaigns on Ads Manager. Facebook’s ad sales team
could focus on helping them manage and optimize their accounts and
addressing any issues they had. These services helped Facebook retain
advertisers and reduce churn.
The ISO steered advertisers towards Ads Manager and the OSO
supported advertisers using Ads Manager through the Ticket Processing
System, an email-based response support system, as well as through
one-to-many support systems, such as webinars and FAQ.
Some advertisers were not managed by a member of Facebook’s
ad sales team at any point in their advertising lifecycle. Revenue from

21
these advertisers was assigned to the OSO. In the third quarter of 2010,
29% of Facebook’s total ad revenue was completely unmanaged.
From 2008 through 2010 revenue from Ads Manager increased
relative to total ad revenue, growing from 35.3% ($96 million) of
Facebook’s total ad revenue in 2008, to 45.5% ($353.8 million) in 2009,
to 66.9% ($1.253 billion) in 2010. 22 As of the transaction date, Facebook
expected the percentage of revenue from Ads Manager to continue
growing. It anticipated that all ads eventually would be purchased on
Ads Manager because its auction pricing system provided a marketplace
with fair prices.
From
January
through
September
2010
Facebook’s
approximately $1.2 billion in ad revenues was distributed across the
DSO, ISO, and OSO, and between Ads Manager and IOs as follows:

In the third quarter of 2010, 71% ($329 million) of Facebook’s
total ad revenue was from managed accounts. These were the
advertisers that had at any point been assigned a dedicated account
manager from the DSO, ISO, or OSO. The “managed revenue” included
purchases via Ads Manager ($187 million) and by IOs ($142 million).
The advertisers that accounted for the managed revenue received
varying levels of support depending upon how actively they were
managed. The following chart summarizes “Facebook ad revenue by
purchase tool and sales and marketing involvement” in the third quarter
of 2010: 23

includes revenue from Resellers; we assume it does not for purposes of our analysis
and note that the small Reseller volume would not affect the numbers materially.

b.

International playbook

Facebook had an “international playbook” for selling and
marketing ads in the ROW territory, summarized in a September 2010
presentation titled “International Sales Prioritization.” The
international playbook took a “market coverage approach.” It assigned
one of four levels of sales coverage to a country by considering whether
that country met certain criteria. The table below, from a slide titled
“International Playbook - Minimum Target Criteria,” details the four
coverage levels and associated criteria.

These criteria—the ratio of MAUs to total internet users within a
country, the number of active users, the amount of revenue generated
from Ads Manager, ARPU, and the size of the online ad market—reflect
how monetizable Facebook projected a given market to be. More
monetizable markets received greater coverage, and therefore a greater
commitment of resources from Facebook’s ad sales team.

23
i.

Ad sales team

By the transaction date, Facebook had nine international sales
offices located in highly monetizable markets, where it wanted its ad
sales team physically located in the markets of the advertisers and ad
agencies with whom they worked: London (Facebook UK), Paris
(Facebook France), Milan (Facebook Italy), Hamburg (Facebook
Germany), Madrid (Facebook Spain), Stockholm (Facebook Sweden),
Sydney (Facebook Australia), Auckland (Facebook New Zealand), and
Singapore (Facebook Singapore). 24 These offices were staffed by
members of Facebook’s DSO. We refer to these offices collectively as the
“FB Foreign Sales Affiliates.”
The DSO provided ad sales and account management services for
the largest advertisers in the international markets, as in the domestic
ad market. In countries that met the criteria for the second-highest
monetization level, Facebook’s ad sales team serviced advertisers
through a nearby office functioning as a regional hub. Before the
transaction date, for example, Facebook Sweden employees covered
Norway, Denmark, and Finland, and Facebook Germany employees
covered Switzerland and Austria.
As for the remaining markets that did not warrant coverage from
an in-country team or from a regional hub, Facebook used both the ISO
and the OSO to provide customer service support. Facebook Ireland
“housed” the international members of the ISO and OSO ad sales teams.
ii.

Resellers

In the lower priority markets, Facebook also contracted with
Resellers to “resell” ads. Its general goal was that after two or three
years of coverage by a Reseller, a market would be ready to graduate to
coverage by a regional hub. An in-country office required more resources
than a regional hub, which in turn required more resources than
contracting with a Reseller.
Facebook entered into Network Affiliate Agreements (NAAs) with
Resellers. 25 Resellers took a revenue-based commission specified by the
24 The record is unclear as to whether the Auckland, New Zealand, office was

open as of the transaction date.

25 The NAAs predating the transaction were between Resellers and “Facebook,
Inc., a Delaware corporation.” They were assigned to Facebook Ireland as part of the

24
applicable NAA. NAAs covered the following countries (with specific
commissions noted in parentheses): South Africa, Nigeria, Kenya, and
Ghana (30%); Czech Republic (20%); Poland (20%); Saudia Arabia,
United Arab Emirates, Bahrain, Oman, Qatar, Kuwait, Yemen,
Lebanon, Jordan, Egypt, Tunisia, and Morocco (30%); Mexico, Central
America, South America, and the Caribbean (30%); Singapore,
Malaysia, Indonesia, Taiwan, Philippines, Thailand, Vietnam, South
Korea, Japan, Cambodia, Myanmar, East Timor, Brunei, and Laos (25%
originally, 30% as amended); and Israel (30%).
In 2010 Facebook’s ARPU in the Resellers’ countries ranged from
$0.03 to $0.73, with a median ARPU of $0.10. By comparison, its ARPU
for all international markets was $2.38. Resellers were limited to selling
in their designated markets. Under some NAAs, Facebook reserved the
right to remove countries from a Reseller’s “territory” upon written
notice. Under others, Facebook and the Reseller could agree to add
countries to the Reseller’s territory.
Resellers had to deliver to Facebook an executed IO that was
subject to Facebook’s prior review and approval. Additionally, each IO
had to meet a monthly minimum sales threshold unless Facebook
approved an exception in writing. These thresholds ranged from $4,350
to $10,000 in net monthly sales. Resellers could make these IO sales
only to a select group of advertisers, a dedicated list controlled by
Facebook. The Resellers’ limited sales role reflects the third-tier status
of their markets in Facebook’s international playbook.
Under the NAAs, Facebook was not restricted from selling ads in
the Resellers’ markets. It could, and did, cover these markets
concurrently with Ads Manager, serviced by the ISO and the OSO,
reflecting Ads Manager’s global accessibility. Facebook paid Resellers a
commission only for sales made through IOs. Facebook did not
compensate Resellers for any of the ads sold through Ads Manager even
if the Resellers were involved in the sales.
The NAAs varied in duration, but they generally were short term
(one year) and could be terminated by either party for any or no reason
upon 30 days’ prior written notice. This reflected the Resellers’
temporary role in Facebook’s expansion in international markets.
transaction. The Assignment Agreement was undated, but we assume it was signed
around the same time as the CSA (on November 12, 2010). The NAAs have different
effective dates, but those details are not relevant to our analysis.

25
Reseller activities accounted for less than 3% of Facebook’s 2010 total
ad revenue in the ROW territory. 26
c.

Advertising agencies

Advertising agencies also purchase ads for advertisers, working
as intermediaries between the media owner (here, Facebook) and
advertisers. They work with the advertiser to plan the proper
advertisement, channel, and budget. Facebook built long-term
relationships with global advertising agencies. It preferred working
with large agencies because they matched its scale.
2.

Nonadvertising revenue

Facebook generated almost all of its non-ad revenue
(approximately 5% of total revenue) from a 30% fee on redemptions of
Credits. “Credits” refers to Facebook’s virtual currency that allowed
Facebook users to use a single form of payment across apps on Facebook
Platform.
Launched in May 2007, Facebook Platform, is a collection of
external APIs and tools that enable third-party developers to develop
apps that link to and operate with or within the Facebook site.
Developer apps accessible through Facebook Platform contributed to
user engagement on Facebook. Some of the most popular developer apps
on Facebook were for social games, such as FarmVille and Tiki Resort
(depicted below).

26 Petitioner’s valuation expert, Dr. Unni, estimated the amount to be $22
million (2.7%) and respondent’s internet advertising expert, Ian Maude, estimated it
to be $21 million (2.6%). Either way it was a small fraction of the total revenue.

26

Facebook gave developers access to certain user data, and
required developers to comply with the terms and conditions set forth in
Facebook’s Platform Policy. Facebook did not charge developers any fees
for access to Facebook Platform.
Both Facebook and the developers could earn revenue by serving
ads to Facebook Platform users. Facebook could display ads on the side
bar, and developers could display ads on Facebook’s framed Canvas page
that shows the developers’ content (the part that displays the game in
the screenshot above).
Facebook also sought to monetize Facebook Platform through
Credits. Users bought Credits from Facebook that they then could use
to purchase virtual goods in-app. Facebook retained a 30% fee when a
user paid with Credits. The third-party developer that created the app
received the remaining 70%. Facebook settled on this revenue split after
reviewing what competing platforms (e.g., the Google Play and Apple
iTunes stores) charged. Facebook believed this familiar model was the
simplest for developers to accept.

27
Facebook began rolling Credits out to certain developers’ apps in
May 2009, two years after it launched Facebook Platform. As of the
transaction date, Credits were not available to all developers, and their
use was not mandatory.
C.

Facebook’s brand and other marketing intangibles

Facebook expected its marketing intangibles, including its
trademark and brand, to contribute to its growth. Facebook developed
its brand around connecting and sharing, openness, and “authentic
identity” (that users provide their real names and are who they say they
are). Facebook’s users and its marketing intangibles strengthened each
other—users enhanced the brand and the brand contributed to
Facebook’s ability to attract more users.
Facebook’s branding also extended to employee recruiting; there
its brand championed aspects of working for Facebook, including
hacking, innovation, and impact. In this context, “hacking” refers to an
engineer’s freedom to develop products and technology. Facebook
showcased its distinct technical challenges and innovation capabilities
by, for example, open sourcing its code (making it available to the public
for free). Facebook emphasized that its engineers could make changes to
the product soon after starting, and could have an impact (because of
the comparatively small engineering team and large user base).
Facebook anticipated that this recruitment brand would attract
engineers.
D.

Business strategy challenges

Notwithstanding its success growing and monetizing users,
Facebook was worried that it would become a fad—that users might
engage less on Facebook in favor of trendy new social or technological
platforms. This was how Facebook displaced MySpace.com, a competing
social networking site, around 2008 to 2009. Facebook faced competition
from other social networking sites both in the United States and globally
in growing its user base and keeping users engaged. It also faced
competition for users’ attention from traditional and online media.
Facebook subscribed to the mantra that “only the paranoid survive.” For
example, Facebook held a “lockdown” in July 2010 to address the
introduction of another social media product, Google+.
Facebook’s ability to attract, retain, and serve its users depended
upon the attractiveness and reliability of its products and the quality of
their underlying technical infrastructure. The rapid pace of change in

28
technology forced Facebook to adapt to maintain and grow its user
community and to keep users engaged.
During 2010 Facebook’s user base grew rapidly from
approximately 350 million to 600 million MAUs, causing scaling
challenges. Storing and making use of exponentially expanding user
data strained Facebook’s software and hardware infrastructure,
requiring it to innovate constantly. Facebook’s global hardware and
software infrastructure as of the transaction date were inadequate to
support the number of MAUs it was projecting—its infrastructure would
not be able to handle the increase in data from more users and the richer
content they were sharing (such as videos). 27 Facebook knew its
infrastructure would need to improve to support the growing number of
users and to avoid disruptions in site performance.
Another opportunity for (and risk to) Facebook’s achieving its
user projections was the “platform shift” from desktop to mobile. At the
time Facebook still was primarily a desktop destination. Facebook’s
2010 mobile offerings included a text-only (no photos) site, a mobile
browser site, and rudimentary web-based mobile apps. These offerings
were popular with users; more than 190 million MAUs accessed
Facebook through mobile products, including nearly 160 million MAUs
in the ROW territory. But these mobile products provided significantly
fewer features than its desktop product, and the diminished experience
was not a viable long-term mobile solution to attract and retain users.
Developing an engaging mobile product would require Facebook
to adapt its infrastructure, development process, and workforce. As of
the transaction date, Facebook’s infrastructure almost exclusively
supported desktop services, and the existing developer tools and product
release process did not facilitate mobile development. Most of Facebook’s
574 engineers did not know mobile-specific programming languages
such as Objective-C or Java.
Facebook’s first attempt to build an engaging mobile app at scale,
Faceweb, launched in fall 2010, failed. In late 2011 Facebook began
hiring new engineers and retraining existing engineers to develop a
native mobile product that did not depend on the desktop site. It finally
launched true native mobile products in 2012.
27 The risk of managing growing demand is familiar. See Amazon I, 148 T.C. at
126–27 (noting need to increase scale was a driving factor in Amazon’s need for
technological innovation and discussing scale limitations of its technology).

29
Facebook also faced pressure to further develop artificial
intelligence and machine learning (AI/ML) capabilities to curate content
for users (including ads they would find engaging) and to protect users
from spam or inappropriate content as the universe of potential content
continued to expand. Facebook’s AI/ML capabilities were insufficient to
address the challenges it anticipated. The rise of rich media, such as
photos and videos, heightened the challenges and risks. In the following
years, Facebook rewrote or replaced much of the AI/ML technologies it
possessed as of the transaction date.
As with users, Facebook’s ability to attract, retain, and serve
advertisers depended upon the attractiveness and reliability of the
Facebook ad products and their underlying technical infrastructure. To
achieve its ad revenue projections, Facebook anticipated that it would
need to innovate its advertising technology.
Advertisers were intrigued by the size of Facebook’s user
community (its “reach”) and its demographic data on those users (its
ability to target people based on their authentic identity). But
advertisers remained skeptical of the effectiveness of advertising on the
Facebook site because social media was still new and because Facebook
at the time lacked the ability to show advertisers the metric they cared
most about: their return on investment (the money spent advertising on
the site). At the time of the transaction, Facebook had not developed an
effective ads conversion tracking tool that could follow users after they
left the Facebook site to determine whether the ad shown to them
induced the action desired by the advertiser.
In 2010 Facebook sold desktop advertising exclusively; it did not
display ads on its mobile website or its then-existing mobile apps. Until
Facebook started monetizing mobile users, it faced the risk that its
mobile user growth would “cannibalize” its desktop revenue—that
increasing unmonetized mobile use would consume its monetizable
desktop business. To display mobile ads, Facebook also would need a
place to put them. But the screen on mobile devices was smaller and
Facebook’s mobile site did not have a side bar, unlike the desktop site.
That left News Feed as the only option. Facebook had tried ads in News
Feed in 2006 through an ad product, Sponsored Stories, that it later
abandoned. And with the shift to mobile, the ability to track users’
activity after they left Facebook’s site (or mobile app) could become more
difficult and therefore posed an additional risk to Facebook’s ad
business.

The fight over how to value the platform contributions hinges, in
part, on what Facebook Ireland contributed to the CSA. We discuss next

2009 Agreements

The 2009 Agreements included: the “Intangible Property License
Agreement” (IPLA), the “Growth and Development Services Agreement”
(GDSA), the “General and Administrative Services Agreement” (GASA),
the “Expense Reimbursement Agreement” (ERA), and the “Sales Costs
Reimbursement Agreement” (SCRA). FIH and FIL were parties to the
28 These figures are petitioner’s; respondent’s opening brief stated that 329
people were employed by FIL or the FB Foreign Sales Affiliates. In any event, the
precise numbers are not critical to our analysis.

31
ERA. The other 2009 Agreements were between FIH and Facebook US.
The 2009 Agreements were executed in December 2009 but generally
had a stated effective date in January 2009. Petitioner has not taken the
position that it intended the 2009 Agreements to constitute a CSA. Nor
did Facebook prepare transfer pricing documentation for any
transactions between Facebook US and Facebook Ireland for tax year
2009. The 2009 Agreements called for various written reports to be
prepared. None were. They terminated as of the transaction date.
Under the IPLA, Facebook US granted Facebook Ireland a
nonexclusive license to use the Facebook System, Marks, 29 and
Confidential Information (as those terms were defined) “to develop,
promote, expand and maintain online social networking communities of
users, advertisers and developers” outside the United States and
Canada (the ROW territory). 30 The IPLA provided that Facebook US
was “the owner, or authorized licensee, of all rights, title and interests
in and to all of the Facebook System, Marks and . . . Confidential
Information” and that Facebook Ireland “shall acquire no rights
whatsoever” to the licensed rights “except as specifically provided” in the
IPLA. With limited exceptions, immediately upon termination (which
either party could do without cause upon 90 days’ prior written notice),
Facebook Ireland had to “cease all use of the Facebook System, Marks
and . . . Confidential Information.”
The IPLA stated that Facebook Ireland would pay Facebook US
royalties of 25% of Facebook Ireland’s net revenues. Facebook Ireland
did not pay Facebook US any royalties pursuant to the IPLA. And
because Facebook US recorded all revenue from international markets
for the duration of the IPLA, Facebook Ireland did not owe royalties to
Facebook US.
Through two other agreements—the GDSA and the GASA—
Facebook US agreed to perform certain development and general and
administrative (G&A) services for Facebook Ireland, for which Facebook
Ireland agreed to reimburse Facebook US. Facebook US did not submit

names.

29 The term “Marks” generally included trademarks, service marks, and trade

30 Facebook generally used the term “international territory” for this; we will
use ROW territory to avoid implying that the 2009 Agreements and the CSA covered
different territories.

32
written reports or invoices to Facebook Ireland pursuant to the these
agreements, or upon their termination.
B.

Sales and Marketing Service Agreements

Under the Sales and Marketing Service Agreements (SMSAs),
Facebook Ireland contracted with certain FB Foreign Sales Affiliates for
their in-country ad sales services, agreeing to pay an 8% markup on
costs. The FB Foreign Sales Affiliates with whom Facebook Ireland had
SMSAs included: Facebook UK, Facebook Australia, 31 Facebook
Sweden, Facebook Italy, Facebook Spain, Facebook Germany, and
Facebook Singapore. Because before September 2010, Facebook Ireland
lacked the accounting systems to book revenue, through a separate
agreement, Facebook US agreed to bear the expense of paying the FB
Foreign Sales Affiliates for their ad sales services. 32

31 The Australian Tax Office (ATO) audited Facebook Australia for tax years
2009 through 2013. At issue was whether consideration received by Facebook
Australia for providing certain sales, marketing, and other support services to related
parties (Facebook US and Facebook Ireland) was arm’s length. From May 1, 2009, to
January 1, 2010, Facebook US compensated Facebook Australia at cost plus 10% for
those services. From January 1, 2010, through the transaction date, Facebook Ireland
compensated Facebook Australia on a cost-plus-8% basis. Facebook represented to the
ATO “that a mark-up on costs of 8% is arm’s length.”
32 Under the ERA between FIH and FIL, FIL and FIH intended that Facebook

US would bear the “Direct Sales Expenses” related to current revenue generation by
reimbursing FIL directly or indirectly (reimbursing FIH after it reimbursed FIL), and
FIH would bear “Market Development Expenses” related to future revenue generation
in the “Territory” (defined as the international market). To the extent that FIL’s
reimbursements under the SMSAs were Market Development Expenses, FIH agreed
to bear those costs. The ERA defined Market Development Expenses as
costs incurred by [FIL] in connection with activities performed by [FIL]
or by an Affiliate related to market development of the Territory,
including . . . marketing and demonstrating the Facebook website,
advertising system, developer platform, community features and
procedures; providing market and strategic analysis; and other similar
activities which are intended to develop or support future revenues to
advertisers . . . in the Territory.
Under the SCRA between Facebook US and FIH, Facebook US, in turn, agreed
to reimburse FIH for the Direct Sales Expenses FIH was incurring (or rather, was
being allocated). The SCRA defined Direct Sales Expenses as
selling costs, including commissions paid to sales employees for
advertising sales and that portion of commissions or fees paid to an
Affiliate, which are incurred by [FIH] but which are directly allocable

Statement of Rights and Responsibilities

Before the transaction date, Facebook had in place terms and
policies that governed its relationship with users, advertisers, and
developers; by early 2009, these were contained in Facebook’s Statement
of Rights and Responsibilities (SRR). The SRR included by reference
Facebook’s Platform Policies, which applied to developers, and
Facebook’s Advertising Guidelines, which applied to advertisers. For a
time, the SRR also included by reference Facebook’s Privacy Policy; the
Privacy Policy later became a stand-alone document. Every person who
registered for and used Facebook agreed to comply with its terms and
policies. As of August 2010, the agreement was with Facebook US if the
user was in the United States or Canada, and with Facebook Ireland if
the user was in the ROW territory.
D.

Octazen acquisition

In February 2010 Facebook acquired Octazen Solutions
(Octazen). Octazen had developed technology that could import contacts
from various email domains (Octazen technology). Acquiring the
Octazen technology (and the engineers who developed it) significantly
improved Facebook’s contact importing capabilities. Facebook US
acquired Octazen through a stock purchase, by its U.S. subsidiary
Facebook Global Holdings II, LLC, of Bonus Energy Sdn Bhd (the
company that owned Octazen in February 2010) for $375,000 and three
milestone payments in the future. 33
In February 2010 Facebook US recorded an intangible asset
purchase for $375,000 under the description “Octazen acquisition.” 34
Facebook Ireland had not recorded any entries on its books and records
relating to the Octazen acquisition as of the transaction date. In
December 2010 FIL and Facebook Malaysia executed two agreements
with a March 2010 effective date (approximately six months before FIL
elected disregarded entity status in September 2010). In one, Facebook
to the external gross revenue derived from advertising sales to
advertisers with invoicing or billing addresses in the Territory which
is recognized by [Facebook US].
33 In June 2010 Bonus Energy Sdn Bhd changed its name to Facebook Malaysia

Sdn Bhd (Facebook Malaysia).

34 The financial accounting experts, Michelle Hanlon (for respondent) and
Robert Wentland (for petitioner), both noted issues with this entry, namely, that it
reflects an asset purchase rather than a stock purchase and it does not say to whom
the $375,000 cash was paid.

34
Malaysia agreed to assign rights in intangible property to FIL. In the
other, FIL retained Facebook Malaysia as an intangible property
developer. Accounting entries for FIL and Facebook Malaysia dated
December 31, 2010, appear intended to record these agreements, but on
that same date the recorded entries were then reversed. In October 2011
FIL recorded the Octazen intangible property for financial accounting
purposes. 35
III.

CSA agreements
A.

The CSA

The CSA was embodied in the “Agreement to Share Costs and
Risks of Online Platform Intangible Property Development.” Under the
CSA, Facebook US and Facebook Ireland agreed to share IDCs in
proportion to their respective RAB shares. 36 They divided all interest in
cost shared intangibles into two nonoverlapping territories—Facebook
US’s domestic territory and Facebook Ireland’s ROW territory—and
assigned the perpetual and exclusive right to exploit the cost shared
intangibles accordingly. 37
Cost shared intangibles were defined to include the following
intangible property reasonably anticipated to be developed under the
CSA: “[i]mprovements, updates, adaptations, or other modifications to,
or a complete replacement of, the [FOP technology],” and related
intangible property. 38 The FOP technology was defined, in part, as

35 Facebook Malaysia was still named Bonus Energy Sdn Bhd as of the March

2010 effective date. It changed its name three months later, in June 2010. Thus, it was
named Facebook Malaysia as of the December 2010 execution date.
36 See Temp. Treas. Reg. § 1.482-7T(b) (“A cost sharing arrangement is an
arrangement by which controlled participants share the costs and risks of developing
cost shared intangibles in proportion to their RAB shares.”).
37 See id. subparas. (1)(iii) (“Each controlled participant must receive a non-

overlapping interest in the cost shared intangibles without further obligation to
compensate another controlled participant for such interest.”), (4)(ii) (permitting and
providing method for territory-based divisional interests).
38 See id. paras. (j)(1)(i) (“Cost shared intangible means any intangible, within
the meaning of § 1.482-4(b), that is developed by the IDA, including any portion of such
intangible that reflects a platform contribution.”), (k)(1)(ii)(B) (requiring a CSA to
“[d]escribe the scope of the IDA to be undertaken and each reasonably anticipated cost
shared intangible or class of reasonably anticipated cost shared intangibles”).

35
the hardware and software system, . . . in existence on [the
transaction date], . . . that facilitates the sharing of data
between users for social networking purposes, sales of
credits and virtual items, development of applications by
developers, delivery of targeted advertisements to user
pages, and any related processes or technology that relates
to facilitating communication and social networking among
users and serving advertisements.
The CSA’s definition of cost shared intangibles explicitly excluded the
user community rights and marketing intangibles transferred in the
“User Base Transfer and Marketing Intangibles License Agreement”
(UBMI license).
The CSA specified the functions and risks that Facebook US and
Facebook Ireland would undertake in their respective territories. 39 In
connection with the CSA, Facebook Ireland would pay its RAB share of
IDCs for each year by making CST Payments, and would bear the risk
associated with making those payments.
Facebook US and Facebook Ireland committed to share
“Aggregate Allocable IDCs.” The Aggregate Allocable IDCs did not
include “Territory Specific IDCs,” which were individually borne by a
participant and pertained solely to the territory that participant
exploited. The CSA provided a method for calculating RAB shares for
purposes of sharing the Aggregate Allocable IDCs. RAB shares were
measured by “the ratio of the [NPV] of the aggregate gross profit of [one
p]arty divided by the [NPV] of the aggregate total gross profit of both
[p]arties.” In this context, the gross profit amounts were the gross profits
in the current fiscal year plus projected gross profits for the following
two fiscal years. 40
Facebook US and Facebook Ireland agreed to “review the actual
and projected financial data” from the use of the cost shared intangibles
“[f]rom time to time.” They also agreed to “amend the cost sharing
methodology as necessary on a prospective basis to reflect changes in”
39 See id. para. (k)(1)(ii)(C) (requiring a CSA to “[s]pecify the functions and risks

that each controlled participant will undertake in connection with the CSA”).

40 See id. subdiv. (ii)(E) (requiring a CSA to “[p]rovide a method to calculate
the controlled participants’ RAB shares, based on factors that can reasonably be
expected to reflect the participants’ shares of anticipated benefits, and require that
such RAB shares must be updated, as described in paragraph (e)(1) of this section”).

36
their RAB shares “and/or the reliability of the measure provided [under
the CSA] as the most reliable estimate of those benefits.”
Facebook Ireland agreed to perform certain functions in the ROW
territory, including to: “develop and manage the user, application
developer, and advertiser communities”; “perform marketing activities”;
“perform administrative functions such as facilities management,
information services activities, human resource management, and tax
and legal department activities”; “perform all operational functions that
enable and maintain the performance of” the FOP technology, including
ad operations, user operations, support, and user growth and
optimization; “select, hire, and supervise employees . . . to perform”
these functions; and “operate or manage data centers as necessary.”
Facebook Ireland also agreed to bear risks in the ROW territory,
including: “[m]arket risks”; “[l]egal and regulatory risks associated with
operating an on-line business”; “[i]ntellectual property protection risks
and . . . infringement risks”; “[b]usiness risks relating to [the ROW
territory] including . . . credit risk, collections risk, market risk, and
asset risks”; and “[r]isk associated with political unrest and foreign
exchange rate fluctuation.”
The CSA had an initial term of five years. It automatically
renewed for successive one-year terms thereafter unless terminated.
B.

FOP technology license and UBMI license

In connection with the CSA, Facebook US and Facebook Ireland
concurrently entered into two additional agreements that conveyed
resources or rights to Facebook Ireland: the “Online Platform Intangible
Property Buy-In License Agreement” (FOP technology license) 41 and the
UBMI license.
In the FOP technology license, Facebook US granted Facebook
Ireland the existing rights to the FOP technology through an exclusive,
perpetual, irrevocable license in the ROW territory. Specifically, it
licensed to Facebook Ireland the “Facebook US PCT Property,” defined
as “all Intangible Property [(as defined in Treas. Reg. § 1.482-4(b),
excluding the user community rights and marketing intangibles)],
including computer software, relating to the [FOP technology] existing
41 See id. para. (b)(3) (“The controlled participants must enter into a PCT as of
the earliest date on or after the CSA is entered into on which a platform contribution
is reasonably anticipated to contribute to developing cost shared intangibles.”).

37
and owned or licensed by Facebook US,” in the ROW territory as of the
transaction date. Facebook Ireland then could develop the FOP
technology as part of the CSA and otherwise use and exploit it
commercially, “in particular by providing services to users, application
developers, and advertisers located in” the ROW territory. The FOP
technology license also required that Facebook Ireland transfer to
Facebook US any “Facebook Ireland PCT Property” (defined the same
way as Facebook US PCT Property, but belonging to Facebook Ireland).
As consideration for the rights and licenses granted to it under
the FOP technology license, Facebook Ireland agreed to pay Facebook
US “such arm’s length amounts as required by Treas. Reg. § 1.482-4 and
Temp. Treas. Reg. § 1.482-7T” in the form of contingent annual
payments. Those payments were to be net of any amount due from
Facebook US to Facebook Ireland relating to the Facebook Ireland PCT
Property.
In the UBMI license, Facebook US granted to Facebook Ireland
the rights to the existing Facebook “User Base” and “Marketing
Intangibles” in the ROW territory. User Base was defined as “the
contracts and other relationships with persons comprising the various
user communities developed and maintained by the [p]arties,
information about such users, and networks developed by users on the
various Facebook sites.” “User communities” here appears to refer to the
user, advertiser, and developer communities together. We use the term
“user community rights” to distinguish the rights covered by the UBMI
from “users” or the “user base” (which frequently appeared to mean only
the individuals using the site to connect and share, not the advertisers
or developers). Marketing Intangibles were defined as
trademarks, service marks, trade names, trade dress,
domain names, business marks, designs, packaging,
marketing strategies, customer lists, other marketing
information, registrations, pending registrations and
copyrights to logos or pictorial depictions, any intangible
property associated with any such marks (such as
marketing intangibles and brand name quality control
standards), and other similar marketing intangible
property.
(We similarly adopt the term “marketing intangibles.”) Facebook US
also “contribute[d] to Facebook Ireland all goodwill and going concern

38
value associated with the User Base and Marketing Intangibles” in the
ROW territory.
As consideration for the user community rights and marketing
intangibles licensed to Facebook Ireland under the UBMI license,
Facebook Ireland agreed to pay Facebook US “such arm’s length
amounts as required by Treas. Reg. § 1.482-4” in the form of contingent
annual payments.
In addition to the core agreements, the parties executed ancillary
agreements, including a “Data Hosting Services Agreement” (DHSA), in
which Facebook Ireland agreed to reimburse Facebook US for data
hosting services at cost-plus-10%. We refer to all of the agreements
executed as part of the transaction together as the “CSA agreements.”
The parties also entered into an “Assignment Agreement”
effective September 15, 2010, transferring Facebook US’s rights and
obligations under certain NAAs to Facebook Ireland. 42
IV.

Financial projections

Both parties’ valuation experts value the upfront contributions to
the CSA, and the PCT Payment required in exchange, by projecting
relevant financial items (cashflow or operating income and expenses) for
Facebook Ireland’s ROW territory and then discounting them back to
present value at a rate intended to reflect the market-correlated risks of
participating in the CSA. But they dispute which inputs—including
which financial projections and which discount rate—should be used.
Both parties use Facebook’s Long Range Plan (LRP), Facebook
management’s three-year-projections for September 2010 through the
end of 2013, as a starting point for their financial projections. We too use
the LRP as our starting point for evaluating Facebook’s opportunities
and risks as of the transaction date and the inputs the valuation experts
chose.
A.

LRP financial projections

The LRP is a 110-slide deck that Facebook management
presented to its board of directors (Board) in August 2010. A slide titled
42 We assume the assignment is part of the transaction but do not group it with
the CSA agreements. We note that an amendment to an NAA between Facebook US
and one Reseller, Fox Latin American Channel, Inc., was executed (and made effective)
after the transaction date but before the date the CSA was executed.

39
“3-Year Financial Plan: Why Do This?” listed the reasons for creating it:
to “[i]dentify financial goals,” “[p]rovide context to guide certain
decisions (e.g. facilities needs, financing needs, hiring plans) and enable
alignment across the company,” and to “[o]btain Board feedback and
identify areas for additional consideration.” This slide also stated that
Facebook sought to “[m]inimize resources invested in putting the plan
together (primarily a top-down exercise)” and to “[r]espect [the]
impossibility of predicting the future with anything resembling
precision.”
The LRP presented multiple financial scenarios, each with an
associated set of financial projections. The parties dispute which set of
projections contained in the LRP “reflect[s] the best estimates of the
items projected (normally reflecting a probability weighted average of
possible outcomes)” for 2010 through 2013. See Temp. Treas. Reg.
§ 1.482-7T(g)(2)(vi). They do not dispute how the projections divided
revenue between the domestic and ROW territories.
Respondent, through Dr. Newlon, adopts the projections for the
“Base Case” financial scenario. The Base Case projected revenue from
Facebook’s then-existing sources—digital advertising (Ads Revenue)
and redemptions of Credits on Facebook Platform (Credits Revenue)—
and from Other Revenue (revenue not attributed to a known source). For
2013, Ads Revenue and Credits Revenue amounted to approximately
$8.1 billion and Other Revenue made up the remaining $1.9 billion, for
a total of $10 billion. Other Revenue thus “plugged” the gap between the
revenue Facebook projected from existing sources and the $10 billion
total revenue forecast for 2013. Petitioner adopts the “Downside, Excl.
‘Other’ Revenue” financial scenario that, as its title indicates, excluded
Other Revenue from projected revenue (this is the only way in which it
differs from the Base Case).
Because we must decide which set of financial projections in the
LRP should be used to estimate the value of the upfront contributions
and the PCT Payment required to compensate for those contributions,
we detail how the LRP was developed, how it reflected the opportunities
and risks that Facebook perceived at the time, how Facebook used the
Base Case internally, and how an investment bank treated the Base
Case when conducting due diligence for a potential equity investment in
Facebook.

40
1.

LRP development

Facebook’s finance team, led by its chief financial officer, David
Ebersman, started working on the LRP in early 2010. It began by
hosting a “hackathon” to brainstorm what the LRP would include. In the
following months, members of Facebook’s management team (referred
to as the “M team”) provided input on various items projected in the
LRP, including users, revenue, and operating costs (namely, capital
expenditures and headcount).
Susan Li, one of the finance team’s analysts responsible for
preparing revenue projections, developed a detailed forecast for 2011
through 2013. This involved projecting revenue from advertising,
Credits, and an “other” category containing virtual gifts and other
miscellaneous, de minimis revenue streams (amounting to
approximately $13 million each year). The finance team strove to
produce a 50/50 forecast, in which Facebook would exceed or miss the
forecast equal parts of the time. As of June 2010 this bottoms-up forecast
projected just over $8 billion in worldwide revenue for 2013. Facebook’s
chief operating officer, Sheryl Sandberg, expressed hesitancy over
Facebook’s ability meet these targets. In a June 2010 email exchange
that included Mr. Ebersman, she stated: “My gut—and this is pure gut—
tells me that our current trajectory is to hit $1.9 [billion] or less this year
and then grow by 50% next year and less in 2012.”
In mid-June 2010 Mr. Ebersman provided a draft of the LRP to
Mr. Zuckerberg, Facebook’s founder, chairman, chief executive officer,
and controlling shareholder, in anticipation of meeting with him to
discuss it. He told Mr. Zuckerberg that the plan was to build around the
medium revenue case in the draft, which reflected the bottoms-up
forecast of just over $8 billion in worldwide revenue in 2013.
Mr. Zuckerberg set the 2013 revenue forecast at $10 billion,
instructing Facebook’s finance team to add Other Revenue to the Base
Case forecast to produce that number. Mr. Zuckerberg’s decision to
increase the 2013 revenue target was contentious internally. But Mr.
Zuckerberg generally viewed Board meetings as an “open
conversation”—an opportunity to discuss Facebook’s biggest issues, both
opportunities and challenges, even if he did not yet have a solution.
Mr. Zuckerberg understood that the finance team was forecasting
how Facebook’s existing products were going to perform. He also
acknowledged that the finance team’s revenue projections had been

41
accurate in the past and thought that their projection here may have
been a little optimistic. Nonetheless, he thought that Facebook should
perform better. He wanted to challenge the M team and other Facebook
employees to do better. And he wanted to avoid the tendency to forecast
just the things that existed. He believed Facebook “could create new
things, and over a multi-year period, they could ramp up to be something
meaningful” and ultimately deliver a better result.
Drafts of the LRP after Mr. Zuckerberg’s mid-June 2010 input
projected $10 billion in revenue in 2013 as a top-down estimate. In the
breakout of revenue by segment, the “Other” category was increased
from a de minimis revenue stream ($13 million in 2013) to an amount
that represented the difference between the bottoms-up (approximately
$8 billion) and top-down ($10 billion) forecasts. At least one of these
drafts asked whether Facebook was “comfortable with a ~$2Bn ‘tbd’ plug
for the 2013 revenue forecast?” and listed “$2bn ‘other’ revenue” as an
item for followup.
In the final LRP presented to the Board in August 2010 the “Base
Case” scenario included an Other Revenue “plug” amount of zero for
2011, approximately $100 million for 2012, and approximately $1.9
billion for 2013. The final LRP also retained questions about the $10
billion revenue forecast for 2013, as we detail below.
In addition to the Base Case, the final LRP included three other
scenarios. The downside scenario labeled “Excl. ‘Other’ Revenue” simply
excluded Other Revenue (as its label implies). It forecast $3.5 billion,
$5.9 billion, and $8.1 billion for 2011, 2012, and 2013, respectively. The
scenario labeled “Excl. ‘Other’ & Credits Rev.” excluded both Other
Revenue and Credits Revenue. The scenario labeled “Upside” adopted
revenue figures of $5 billion, $10 billion, and $15 billion for 2011, 2012,
and 2013, respectively.
2.

Key projections in the final LRP Base Case
a.

User growth

The LRP projected that Facebook’s global MAUs would grow from
519 million in September 2010 to 600 million by the end of 2010, 834
million by 2011, 1.025 billion by 2012, and 1.195 billion by 2013. This
reflected Facebook’s strong position in the social media industry in 2010;
it was the largest social network in the world. Overall Facebook was in
a dominant position in its industry because it possessed the largest user
community and its user community was rapidly growing. But the LRP

42
also identified risks to user growth and engagement including
“[s]aturation points in key countries,” “[d]ecreased engagement,” and
“[c]ompetition.”
The LRP reflected Facebook’s concern about user churn, which
hurt user growth. Churned users were those who became “stale” (users
whose last action was over 30 days ago) or “deactivated” (users who
deactivated, but did not delete, their accounts). The LRP noted that,
despite increasing user churn, Facebook added 30 million MAUs in July
2010 and mobile growth “reaccelerated.” It stated that Facebook’s team
was “focused on reducing churn, better engaging new and low-activity
users, and combatting fake accounts/spam across the site.”
The LRP also mentioned the risks of site reliability, user
discomfort with sharing personal information, and safety concerns as
challenges to maintaining and growing its user base. To achieve its user
growth projections in the LRP, Facebook anticipated that it would need
to surmount various risks through innovations to the FOP technology.
The LRP made assumptions and projections regarding Facebook’s
users. It stated: “Mobile helps drives [sic] adoption around the world.” It
assumed that global internet growth would continue each year through
2013 to more than 2.5 billion users. And that the “plan ends 2013 with
1.2B users (compared to ~900M for Google and ~600M for Yahoo today).”
It also “assume[d] average user engagement (ad opportunities per user)
[would] stay[] relatively flat.”
b.

Financial projections
i.

Ads and Credits Revenue

For 2013 the LRP projected revenue from two existing sources,
Ads and Credits. Together, Ads Revenue and Credits Revenue were
projected to grow from approximately $1.9 billion in 2010 to
approximately $8.1 billion by 2013. Ads Revenue was projected by
taking the product of the user projections and ARPU. It was projected to
grow from approximately $1.8 billion in 2010 to approximately $6.7
billion in 2013, for a compound annual growth rate (CAGR) of 55%. The
LRP projected Credits Revenue to grow from under $100 million in 2010
to approximately $1.4 billion in 2013, reflecting a CAGR of 148%. It also
listed the ability to ramp up Credits Revenue at this rate as a risk.
The LRP indicated that Facebook’s ads business would grow
significantly. It stated that “[o]verall online ads spend should continue

43
to grow at a healthy pace.” It noted that while Facebook then only
accounted for “3% of online ad spend (vs. ~$50% for Google and 15% for
Y[ahoo]!),” it anticipated that by 2013 it would grow its share to 7%. The
LRP stated that Facebook predicted its ads revenue growth would be
driven in equal parts by user growth and ads ARPU growth. It also
stated that in the future Facebook planned to monetize its mobile
platform, framing the shift to mobile as a “key strategic area.”
The LRP also listed “[a]dvertiser [return on investment],
particularly in the direct response business” as a risk. The LRP noted
that in monetization Facebook still lagged behind competitors,
especially those in the search advertising business. It noted, as an
example, that in August 2010, Facebook had roughly the same number
of active users as Google and Yahoo! had had three years earlier, but
Google and Yahoo! were three to six times more effective at monetizing
them. And it included a slide titled “Churn analysis for advertisers”
which highlighted increased net churn even as total accounts grew.
ii.

Other Revenue

Other Revenue was the third source of revenue in the Base Case.
The LRP framed the Other Revenue target as aspirational. “Achieve
$10B in annual revenue in 2013” was listed as a “proposed financial
goal[].” The first bullet point on the slide titled “Key questions for
discussion” asked: “Are we comfortable planning towards a $10B
business?” It noted that this would require “~$3B from Credits and
Other sources” to supplement “~$7B in ads.” Like the ability to ramp up
Credits, the ability to ramp up Other Revenue was listed as a risk.
In describing the Base Case revenue forecast, the LRP stated that
Other Revenue “reflects the expectation that we will identify additional
revenue opportunities over the coming years” and that it “[c]ould come
from expanding [Facebook’s] existing Ads or Credits strategies and/or
from new sources.” “Begin considering ideas for $2B in ‘other’ revenue
by 2013” was listed on the “[f]ollow-up items and next steps” slide.
These caveats were included because Mr. Ebersman wanted to
ensure the Board understood that Other Revenue was a meaningful
portion of the forecast for 2013 but Facebook did not have a plan for
achieving it. Facebook had identified neither a product to generate
Other Revenue nor a market in which it would earn Other Revenue. The
need to explain these caveats was the most memorable part of the
August 2010 presentation for Mr. Ebersman.

44
iii.

Discount rates

The LRP offered discount rates of 12.5%, 15%, and 17.5% on slides
titled “Illustrative valuation ranges ($ per share),” “DCF valuation
comparison ($ per share),” and “Illustrative valuation range detail ($ per
share).” It used these discount rates as part of its discounted cashflow
(DCF) analysis in computing an estimate for the (then) current value of
Facebook’s stock. It listed Baidu, Tencent, and Google as comparables.
iv.

Projected expenses

The two primary drivers of Facebook’s projected expenses in the
LRP were capital expenditures and employee headcount. The LRP
projected that Facebook’s capital expenditures would grow from $709
million in 2010 to $1.294 billion in 2013. It projected an increase in
headcount from approximately 2,140 employees in 2010 to
approximately 7,760 employees in 2013. The LRP also included among
its key assumptions “M&A and Other Contingency” of $50 million, $250
million, and $750 million, for 2011 to 2013, respectively. A cashflow
statement included these business acquisition expenses together with
capital expenditures for purposes of computing cashflows from investing
activities; neither was included in the computation of cashflows from
operating activities.
Facebook did not associate material projected expenses with
Other Revenue. The LRP stated that 2013 free cashflow “could be
overstated if the ‘other’ revenue is not generated from Ads or Credits”
because Facebook “ha[d] not aggressively planned for significant
increased expenses (beyond ~250 heads) to support an entirely new
revenue stream.” Mr. Ebersman and the finance team thought that
planning for expenses attributable to Other Revenue would be a more
useful exercise once Facebook figured out what Other Revenue was
going to be. Comparing the Base Case and the Downside Excluding
Other Revenue indicates that the operating margin for Other Revenue
would have been 94% (92% when accounting for the costs of 250
additional full-time employees).

45
3.

Internal use of the LRP

Soon after Facebook’s M team presented the LRP to the Board, 43
Facebook used it for internal decision-making purposes, and shared it
with employees.
Facebook also provided the Base Case to an accounting firm,
KPMG LLP (KPMG), to value its common stock for compensation
purposes under section 409A. KPMG produced a section 409A valuation
report for the third quarter of 2010 and for quarters thereafter. In these
reports KPMG employed various valuation methods—DCF method,
secondary market transaction method, guideline public company
method—to establish the FMV of Facebook’s common stock. In the
section 409A valuation report for the quarter ending September 30,
2010, it employed a DCF method that incorporated the Base Case
projections. KPMG viewed the Base Case projections as projecting
significant growth that Facebook might not be able to realize.
Accordingly, it added a “[c]ompany specific risk premium” of 6% to the
discount rate it used to convert cashflows to present value, resulting in
a weighted average cost of capital (WACC) of 17%. 44 It employed the
secondary market transaction method as a corroboration method.
B.

Investment bank’s equity investment

In December 2010, Goldman Sachs (investment bank or bank)
considered an investment in Facebook’s common stock. 45 As part of its
43 It is unclear from the record whether formal Board approval was sought or

required.

44 “The WACC provides the expected rate of return for a company on the basis

of the average portion of debt and equity in the company’s capital structure, the current
required return on equity (i.e., cost of equity), and the company’s cost of debt.”
Amazon I, 148 T.C. at 184 n.35 (quoting Veritas, 133 T.C. at 324 n.33).
At trial, the details of the bank’s process for evaluating the prospective
investment was sealed but its identity was not. The investments made by the bank, its
affiliates, and its clients, through a vehicle the bank managed, in December 2010 and
January 2011, significantly exceeded $1 billion. They were disclosed in the Form S–1,
Registration Statement Under the Securities Act of 1933, for Facebook’s IPO. We have
concluded that the high-level details relevant to our analysis need not be sealed given
the age of the transaction and what already is public.
45

We use the term “investment bank” to focus on what is relevant to the analysis:
Roughly contemporaneously to the transaction, an unrelated potential investor
evaluated an investment in Facebook for itself, and for its clients, on the basis of
information provided by Facebook along with its own knowledge, experience, and
expertise.

46
due diligence before making the investment, the bank met with
members of the M team. It reviewed updated Base Case projections
shared by Facebook, historical financials, and business strategy and
prepared a confidential memorandum for its investment committee
summarizing its analysis. 46 The investment bank conducted an analysis
of its required returns for making an investment considering
comparable companies and how those companies traded publicly, and
contemplating Facebook’s future earning potential at selected future
points. The investment bank selected two points—early 2012 (assuming
that an IPO was most likely in this timeframe) and late 2014. It
anticipated that Facebook would be more comparable to some of its
publicly traded peers at those future dates.
In its returns analysis the investment bank used Facebook’s
projections as a starting point to create its own base case. For its base
case the investment bank reduced the revenue projections in Facebook’s
Base Case for each year: by $696 million (18.56%) in 2011, $1.667 billion
(27.78%) in 2012, and $3.235 billion (32.35%) in 2013. The investment
bank applied this haircut to Facebook’s projected Base Case revenue for
two reasons, explained at trial by a former vice president in the bank’s
technology, media, and telecom investment banking group, involved in
evaluating the Facebook investment. First, the bank thought Facebook’s
projections for its current and identifiable revenue streams (Ads and
Credits Revenue) were aggressive. It thought Facebook took an
“optimistic” view of the Facebook Credits business and was generally
“bullish” on the growth of its advertising business. Second, it was
uncomfortable with Facebook’s projections because there was no plan
for generating Other Revenue. The investment bank therefore scaled
back total revenue to produce a more “middle-of-the-road” case for which
it would be willing to invest.
The bank concluded that an internal rate of return (IRR) in the
range of the “high teens to mid-20s” was necessary for the risk it was
taking by investing in Facebook in 2010. An IRR can generally be viewed
as a “hurdle rate,” or the return an investor aims to achieve. It used a

46 Facebook’s December 2010 presentation to the bank increased its revenue
projections for 2011 to $3.75 billion to reflect increased ads revenue from Ads Manager
but left the revenue projections for 2012 and 2013 unchanged.

47
20% discount rate to compute an NPV of $47B, as of December 2010, of
Facebook’s “[i]mplied” market cap in 2014 of $97B. 47

Financial results

Facebook’s actual revenue, as reported in its Forms 10–K, Annual
Report Pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934, for subsequent years, was $3.711 billion for 2011, $5.089 billion
for 2012, and $7.872 billion for 2013. The actual revenue thus exceeded
the investment bank’s projections but fell short of Facebook’s LRP
projections for 2012 and 2013, even after excluding Other Revenue in
those years. Facebook’s actual revenue did exceed the $10 billion in
2014; Facebook reported revenue of $12.466 billion for that year. This
58% revenue increase from 2013 to 2014 is slightly more than the 55%
increase from 2012 to 2013.
The table below compares the revenue projections in the LRP
Base Case, the LRP Downside Excluding Other Revenue, the
investment bank’s base case, and Facebook’s actual revenue (expressed

Transfer pricing documentation and payments

Facebook, with the help of Ernst & Young LLP (EY), prepared
transfer pricing documentation for the transaction, which was finalized
in September 2011. 48 This transfer pricing documentation consisted of

Respondent points to other projections by the investment bank: a DCF
analysis to arrive at an intrinsic equity value and a public companies comparables
analysis to compute Facebook’s average implied equity value.
47

48 To prepare transfer pricing documentation, EY extended the 2010 LRP
projections through 2020. EY projected operating margins to decrease by 0.5% each
year after 2013 and determined a long-term growth rate of 3% for the terminal value
of Facebook’s expected future cashflows. The parties’ valuation experts cited these
assumptions in preparing their own analyses.

48
three separate reports: a CSA report, an intercompany PCT and license
payments report, and an intercompany service transactions report.
For 2010 Facebook Ireland paid Facebook US (and Facebook US
included in income) total royalties of roughly $100 million. This figure
comprised approximately $60 million for the FOP technology, $38
million for the user community rights, and $3 million for the marketing
intangibles. (The UBMI license did not specify separate royalties for the
user community rights and the marketing intangibles; rather this
appears to be the product of EY’s transfer pricing analysis.) Of the $100
million, Facebook Ireland paid $5 million cash and a $95 million
intercompany note. The royalty amounts were based on the following
NPVs for each category (expressed in millions):
License

$1,685

User community rights

$6,308

In preparing its valuation analysis for the required PCT
Payment, EY included Other Revenue but used a lower operating
margin based on the LRP Downside Excluding Other Revenue scenario.
EY applied the income method to compute the NPV for the rights
transferred by Facebook US to Facebook Ireland under the FOP
technology license using a discount rate of 17.7%, which it derived by
adding a 0.7% international risk premium to KPMG’s 17% WACC for
Facebook.
Facebook and EY concluded that Facebook Ireland would pay the
FOP technology license royalties over four additional years (2011
through 2014), and royalties for user community rights over six
additional years (2011 through 2016). Facebook Ireland made these
49 The transfer pricing documentation prepared by EY states, in part, that
“FIH has agreed to pay FBUS 1% of total international revenue for rights to the
Facebook marketing intangibles under the User and Marketing IP Agreement, which
is within the arm’s length range of results from the CUT search described” in that
documentation. We infer that EY’s reference to the “User and Marketing IP
Agreement” is to the UBMI license which it attached as an appendix. The UBMI
license does not specify a 1% royalty for the marketing intangibles but broadly states
that “Facebook Ireland shall pay to Facebook US such arm’s length amounts as
required by Treas. Reg. § 1.482-4.”

49
payments. Facebook Ireland also was expected to pay the 1% trademark
license royalty in perpetuity (and did pay it throughout the period
covered by the record). 50
EY concluded that Facebook Ireland’s 2010 RAB share was 44%
(and Facebook US’s was therefore 56%). Following the method specified
in the CSA, EY computed this percentage by dividing the NPV of current
and projected gross profit in the ROW territory into worldwide gross
profit. To compute the NPV it again used KPMG’s estimated WACC of
17% for Facebook.
In 2010 Facebook’s total cost sharing pool (i.e., the total amount
of aggregate allocable IDCs paid by both Facebook US and Facebook
Ireland) totaled approximately $49 million. Facebook Ireland bore its
stated RAB share of these costs. After deducting some IDCs that it had
directly incurred, Facebook Ireland made a net CST Payment to
Facebook US of approximately $21 million for 2010.
In October 2013, during the IRS’s examination for Facebook’s
2010 tax year, Facebook responded to an information discovery request
from the IRS broadly describing the Base Case projections in the LRP
as “the most likely scenario to occur.”
VI.

Respondent’s allocations
A.

Notice

The Notice, issued in July 2016, reallocated income on the basis
of respondent’s determination that the NPV of the assets transferred—
the FOP technology, user community rights, and marketing
intangibles—and therefore the NPV of the PCT Payment was $13.88
billion, not the $6.3 billion that Facebook used for computing its 2010
royalties. This reallocation resulted in an increase of approximately $85
million in Facebook US’s gross royalty income for 2010. The Notice did
not separate the adjustment into the three royalties FIH paid Facebook
US pursuant to EY’s documentation.
The Notice also determined that Facebook Ireland’s RAB share
should be increased (and Facebook US’s decreased) which in turn
increased Facebook Ireland’s required CST Payment and reduced
50 It is unclear how Facebook Ireland made these payments (i.e., whether
through a note or cash), but respondent does not dispute that Facebook Ireland paid
some royalties or that it paid the 1% trademark license royalty.

50
Facebook US’s by a corresponding amount. The Notice therefore
decreased Facebook US’s deductions for IDCs by $5.39 million for
2010. 51 Petitioner timely petitioned for redetermination.
B.

Amended Answer

A month before trial respondent filed a First Amendment to
Answer (Amended Answer), 52 increasing his asserted NPV for the PCT
Payment from $13.88 billion to $21.15 billion, on the basis of Dr.
Newlon’s opening expert report. This assertion in turn increased
petitioner’s 2010 deficiency by approximately $2.4 million. The $21.15
billion NPV is the top of the range that Dr. Newlon opined would be
arm’s length in his opening expert report. In his posttrial opening brief
respondent argues that a PCT Payment of $19.945 billion is
appropriate. 53
Respondent also has adopted Dr. Newlon’s calculation of
Facebook Ireland’s RAB share for 2010 (53.5%), which is slightly lower
than the RAB share respondent determined for Facebook Ireland in the
Notice. This adjustment resulted in a decrease of $4.66 million (rather
than the $5.39 million in the Notice) to Facebook US’s deductions for
IDCs for 2010, resulting in a reduced deficiency of $735,020 attributable
to this item.
OPINION
Before we tackle the parties’ legal arguments we address
threshold evidentiary and procedural matters. We first address
petitioner’s contention that respondent raised a “new matter” under
This $13.88 billion NPV determination also resulted in collateral
computational adjustments to Facebook’s net operating loss, a domestic production
activities deduction, and general business credits.
51

52 Two months earlier, we gave respondent a deadline to move for leave to file

an amended answer if he planned to seek an increased deficiency for 2010. This came
after respondent indicated that he might be seeking an increased deficiency on the
basis of what he “intend[ed] to present at trial.” Respondent then filed a Motion for
Leave to File First Amendment to Answer. In our Order granting respondent’s Motion,
we stated that we would allow petitioner to identify any prejudice during the course of
trial and we deferred ruling on the effect of respondent’s amendment on the burden of
proof.
53 Dr. Newlon presents this as the median result falling within a range from
$18.757 billion to $21.147 billion that he determined under his method; respondent
argues that a PCT Payment falling within Dr. Newlon’s range is reasonable and chose
the midpoint.

51
Rule 142(a), shifting the burden of proof to respondent. We then discuss
the extent to which we will consider posttransaction evidence. Finally,
we address the scope and standard of review under section 482.
I.

Burden of proof

The taxpayer generally bears the burden of proving that the
Commissioner’s determinations in a Notice of Deficiency are erroneous.
See Rule 142(a); Welch v. Helvering, 290 U.S. 111, 115 (1933). The
Commissioner bears the burden of proof with respect to “any new
matter, increases in deficiency, and affirmative defenses[] pleaded in the
answer.” Rule 142(a)(1). The Commissioner raises a new matter when
“a notice of deficiency fails to describe the basis on which the
Commissioner relies to support a deficiency determination and that
basis requires the presentation of evidence that is different than that
which would be necessary to resolve the determinations that were
described in the notice of deficiency.” Shea v. Commissioner, 112 T.C.
183, 197 (1999).
In his Amended Answer, respondent asserted an increased
deficiency for 2010 on the basis of Dr. Newlon’s opening expert report.
The parties agree that respondent bears the burden of proof with respect
to the increase. But petitioner contends that respondent’s Amended
Answer also raised a new matter and he therefore has the burden of
proof as to the entire deficiency.
The Amended Answer did not change the statutory basis for
respondent’s (now-increased) deficiency determination. See Abatti v.
Commissioner, 644 F.2d 1385, 1390 (9th Cir. 1981), rev’g T.C. Memo.
1978-392. In the Notice, respondent invoked section 482 to reallocate
income in connection with the transaction. In his Amended Answer, he
also relies on section 482, now reallocating a greater amount of income.
The main issues—the arm’s-length PCT and CST Payments—
remain the same. Respondent now supports his determination with a
different valuation methodology. For reallocations under section 482,
“[t]he fact that the Commissioner relies on alternative theories at trial,
supported by methodology different from that used in the notice of
deficiency, does not necessarily place the burden on the Commissioner.”
Altama Delta Corp. v. Commissioner, 104 T.C. 424, 458 (1995) (citing
Sundstrand Corp. & Subs. v. Commissioner, 96 T.C. 226, 354–55
(1991)); see also Stewart v. Commissioner, 714 F.2d 977, 990 (9th Cir.
1983) (“It is well settled that the assertion of a new theory that merely

52
clarifies the original determination, without requiring the presentation
of different evidence, does not shift the burden of proof.” (citing Achiro
v. Commissioner, 77 T.C. 881, 890 (1981))), aff’g T.C. Memo. 1982-209.
In a posttrial hearing we asked petitioner what different evidence
it would have presented had respondent not amended his Answer.
Petitioner confirmed that it would not have selected a different best
method for estimating the arm’s-length PCT Payment in its case-inchief. Petitioner did note that its experts had to respond, on rebuttal, to
a different method (Dr. Newlon’s income method) that applied different
inputs (financial projections, discount rate, best realistic alternative)
from the method and inputs underlying the Notice. But a rebuttal expert
report should respond to the other side’s case-in-chief expert witness and
the arguments made and evidence presented at trial by the other side
through their expert(s). 54
We have treated a party’s reliance on new expert witness
methodologies in a transfer pricing case as analogous to pursuing
alternative legal theories. See Altama Delta Corp., 104 T.C. at 458.
Changes to expert witness methodologies do not “necessarily” shift the
burden of proof to the Commissioner. See id. (ruling that the
Commissioner’s revisions at trial to the section 482 reallocations in the
Notice of Deficiency did not warrant shifting the burden of proof).
Raising a new statutory provision (e.g., dropping an economic substance
challenge in favor of section 482), by contrast, would shift the burden of
proof. See Achiro, 77 T.C. at 891. Here, petitioner had sufficient notice
of the basis of respondent’s deficiency determination (a section 482
reallocation in connection with the transaction). Shifting the burden of
proof with respect to the entire deficiency therefore is inappropriate.
We conclude that petitioner retains the burden of proof for the
deficiency determined in the Notice and respondent bears that burden
for the increase to that amount in the Amended Answer. Regardless, the
record before us allows us to resolve all issues on a preponderance of the
evidence. The assignment of the burden of proof is not dispositive.

54 Respondent moved to exclude some of petitioner’s rebuttal experts’ reports
as containing “untimely opening opinions.” We denied respondent’s Motion because the
changes that petitioner’s experts made to their valuation methodology and inputs
directly or indirectly challenge respondent’s opening expert reports on the same
subject matter—generally, the arm’s-length amount charged in a PCT.

53
II.

Posttransaction evidence

In resolving the issues before us our focus is on the transaction
date and what was “reasonably anticipated” as of that date. See Temp.
Treas. Reg. § 1.482-7T(c)(1), (j)(1)(i) (defining compensable contributions
by whether they are “reasonably anticipated to contribute to” either
development of cost shared intangibles or exploitation of them). 55 For
example, the regulations direct the parties to use financial projections
that reflect a “probability weighted average of possible outcomes,” and a
discount rate that reflects “the market-correlated risks of activities or
transactions . . . based on all the information potentially available at the
time for which the present value calculation is to be performed.” Id.
para. (g)(2)(v) and (vi). Likewise, estimating RAB shares requires
selecting reliable projections to measure the reasonably anticipated
benefits. Id. para. (e)(1).
Evidence from after the transaction date can help us evaluate
what was reasonably anticipated or expected then. To that extent,
therefore, posttransaction evidence may be relevant. Fed. R. Evid. 401
and 402. We have looked to posttransaction evidence for this purpose in
valuation cases. See, e.g., Estate of Gilford v. Commissioner, 88 T.C. 38,
52 (1987) (permitting consideration of posttransaction date events “for
the ‘limited purpose’ of establishing what the willing buyer and seller’s
expectations were on the valuation date and whether these expectations
were ‘reasonable and intelligent’” (quoting Estate of Jephson v.
Commissioner, 81 T.C. 999, 1002 (1983))). We have considered
posttransaction evidence for this purpose in prior cost sharing cases. See
Amazon I, 148 T.C. at 168 (noting “ex post data” of a contract
amendment that postdated the CSA transaction by 18 months “may
provide a reference point or sanity check”); Veritas, 133 T.C. at 326–27
(comparing Veritas Ireland’s actual growth rate with the growth rate
employed by the Commissioner’s valuation expert during a period
following the tax years in issue and looking to its role in the
international markets during the CSA).
Throughout the trial, respondent objected to petitioner’s
questions about posttransaction events as irrelevant. We overruled this
objection but observed that posttransaction evidence has its limits
55 See also Treas. Reg. § 1.482-1(f)(2)(iii)(A and B) (explaining that “results of
a controlled transaction ordinarily will be compared with the results of uncontrolled
comparables occurring in the taxable year under review” but in certain circumstances
multiyear data may be considered).

54
(affecting weight more than admissibility). 56 Respondent expressed
concern about petitioner’s using posttransaction evidence to highlight
the risks Facebook anticipated as of the transaction date (e.g., the shift
from desktop to mobile) and downplay the corresponding opportunities
(e.g., growing number of mobile users), reminding us that Facebook
encountered these “supposed hiccups” on its way to becoming one of the
world’s most valuable companies.
Petitioner contends that posttransaction evidence is relevant
precisely because respondent disputes testimony from Facebook’s
management and employees about the risks they saw as of the
transaction date. For example, petitioner points to its struggle to
develop a native mobile app, such as the Faceweb failure, to
demonstrate that Facebook was reasonable to view the shift to mobile
as a risk in 2010.
At trial, both parties focused on what was reasonably anticipated
or expected as of the transaction date. They agree that we may look to
what happened after the transaction date to assess the reasonableness
of Facebook’s expectations at the time. Both parties also introduced
evidence and elicited fact-witness testimony about events after the
transaction date as part of their cases-in-chief. And both adopt the
opinions of experts who relied on information from after the transaction
date.
The parties’ fight shows how posttransaction evidence may be
helpful to our evaluation of the parties’ divergent views on Facebook’s
prospects when it entered into the CSA, even as it also illustrates the
limits to its usefulness. We consider posttransaction evidence within
those limits.
III.

Scope and standard of review

We now turn to the scope and standard of review, and a bit of
semantics. The parties agree that we review deficiencies resulting from
the Commissioner’s section 482 allocations de novo, under section 6213.
Instead their focus is on the standard of review; they disagree over the
deference we should afford respondent’s determination.

56 At trial we permitted testimony about posttransaction developments but
cautioned the parties that the more distant the development was the less relevant it
would be.

55
The Commissioner has broad discretion under section 482, and an
allocation will be set
