Case Style: DFS Group, LP v. County of San Mateo

Case Number: A150162

Judge: Stewart

Court: California Court of Appeals First Appellate District, Division Two on appeal from the Superior Court, County of San Mateo

Plaintiff's Attorney: Cris K. O'Neall, Andrew W. Bodeau and C. Stephen Davis

Defendant's Attorney: Rebecca M. Archer

Description: DFS Group, L.P. (DFS), which engages in the business of duty-free sales at
airports around the country, holds an exclusive lease and concession to sell merchandise
duty-free at San Francisco International Airport (SFO), in retail space located within
SFO’s international terminal.
1 This dispute concerns the San Mateo County Assessor’s
(Assessor) reassessment of the value, for property tax purposes, of the possessory
interests DFS obtained under a seven-year extension of its agreement with SFO.
At issue is whether the Assessor’s valuation methodology, by including the value
of DFS’s exclusive concession rights, violated Revenue and Taxation Code provisions
that bar the taxation of intangible rights.
2
Among them, section 110, subdivision (d)(3)
expressly exempts from taxation the exclusive right to operate a concession. It states:
“The exclusive nature of a concession, franchise, or similar agreement, whether de jure or

1
San Francisco International Airport is owned and operated by the City and
County of San Francisco, and the agreement at the heart of this dispute is thus between
DFS and the City and County. For convenience, we refer to the City and County and its
airport collectively as “SFO.”
2 Except as otherwise indicated, statutory references are to the Revenue and
Taxation Code.
2
de facto, is an intangible asset that shall not enhance the value of taxable property,
including real property.”
The Assessor utilized a valuation methodology known as the income method (also
called the “capitalization” method), which estimates the fair market value of an incomeproducing
property by calculating the property’s expected future income stream. (See
Elk Hills Power, LLC v. Board of Equalization (2013) 57 Cal.4th 593, 604–605 (Elk
Hills).) Under that approach, “an appraiser ‘estimates the future income stream a
prospective purchaser could expect to receive from the enterprise and then discounts that
amount to a present value by use of a capitalization rate.’ ”
3
(Id. at p. 604.) There is no
dispute in this case that the Assessor properly used the income method rather than
another valuation methodology. Rather, the dispute turns on how the Assessor applied
that methodology; in particular, on just a single input in its analysis.
In applying the income method, the Assessor valued DFS’s leasehold interest at
SFO based upon the entire fee DFS was required to pay SFO for its rights under their
agreement during the seven-year extension period, in effect treating that entire amount as
economic rent. That fee was a minimum annual guaranteed amount, applicable when
DFS’s gross revenues failed to meet targeted thresholds. DFS contends that this
minimum annual payment to SFO was consideration not only for its taxable use and
occupancy of space at SFO but also for the valuable but non-taxable exclusive concession
rights it obtained under the agreement to sell merchandise on a duty-free basis at SFO. It
argues that by capitalizing the entire payment without deducting the value of its exclusive
concession rights, the Assessor directly taxed those non-taxable intangible rights in
violation of sections 110, subdivision (d) and 212, subdivision (c). We agree and reverse

3
“ ‘ “The income approach may be called the capitalization method because
capitalizing is the process of converting an income stream into a capital sum, i.e., value.”
[Citations.] The assessor capitalizes “the sum of anticipated future installments of net
income from the property, less an allowance for interest and the risk of partial or no
receipt.” ’ ” (Freeport-McMoran Resource Partners v. County of Lake (1993) 12
Cal.App.4th 634, 642.)

the decision of the trial court affirming the Assessment Appeals Board (Board) decision
that approved the Assessor’s methodology.
THE STATUORY SCHEME
Sections 110, subdivision (d) and 212, subdivision (c) generally exempt intangible
assets and rights from taxation. (§§ 110, subd. (d)(1), (3), 212, subd. (c).) These
provisions, adopted in 1995, implement California’s constitutional prohibition on the
taxation of intangible assets and rights (with exceptions not relevant here) and codify the
California Supreme Court’s decision in Roehm v. County of Orange (1948) 32 Cal.2d 280
and its progeny. (See Cal. Const., art. XIII, § 2; Elk Hills, supra, 57 Cal.4th at pp. 607,
617.)
Section 212, subdivision (c) provides, “Intangible assets and rights are exempt
from taxation and, except as otherwise provided in the following sentence, the value of
intangible assets and rights shall not enhance or be reflected in the value of taxable
property. Taxable property may be assessed and valued by assuming the presence of
intangible assets or rights necessary to put the taxable property to beneficial or productive
use.” (§ 212, subd. (c).)
Similarly, section 110, subdivision (d), which defines “fair market value” and “full
cash value,” provides in relevant part: “Except as provided in subdivision (e), for
purposes of determining the ‘full cash value’ or ‘fair market value’ of any taxable
property, all of the following shall apply: [¶] (1) The value of intangible assets and rights
relating to the going concern value of a business using taxable property shall not enhance
or be reflected in the value of the taxable property. [¶] (2) If the principle of unit
valuation is used to value properties that are operated as a unit and the unit includes
intangible assets and rights, then the fair market value of the taxable property contained
within the unit shall be determined by removing from the value of the unit the fair market
value of the intangible assets and rights contained within the unit. [¶] (3) The exclusive
nature of a concession, franchise, or similar agreement, whether de jure or de facto, is an
intangible asset that shall not enhance the value of taxable property, including real
property.” (§ 110, subd. (d).) Section 110, subdivision (d) thus “prevents the direct
4
taxation of intangible rights and assets when assessors use methods of unit valuation.”
(Elk Hills, supra, at p. 608.) However, section 110 contains the same caveat as
section 212, stating that “[t]axable property may be assessed and valued by assuming the
presence of intangible assets or rights necessary to put the taxable property to beneficial
or productive use.” (§ 110, subd. (e).)
Subdivision (f) adds another caveat. It states that “[f]or purposes of determining
the ‘full cash value’ or ‘fair market value’ of real property, intangible attributes of real
property shall be reflected in the value of the real property. These intangible attributes of
real property include zoning, location, and other attributes that relate directly to the real
property involved.” (§ 110, subd. (f).)
This case concerns the thorny intersection between provisions that, on the one
hand, exempt intangible assets and rights from property taxes but, on the other hand,
permit taxing authorities to assume the presence of intangible assets and rights that are
necessary to put the property to beneficial or productive use. Our Supreme Court has
instructed that these provisions are not mutually exclusive, and that even if an intangible
asset is “ ‘necessary to put the taxable property to beneficial or productive use,’ ” that
asset nonetheless may not be directly taxed. (Elk Hills, supra, 57 Cal.4th at p. 614.)
With these general principles in mind, we turn to the facts.
BACKGROUND
I.
Facts
In the 1990s, SFO undertook to replace its old international terminal with a new
one. In connection with that project, while construction of the new international terminal
(“IT”) was still underway, it sought bids for the concession to sell duty-free and other
retail merchandise at the new terminal.
It did so in 1998, in a request for proposal and qualifications (RFP) for a “PostSecurity
Master Retail/Duty-Free Concession in the New International Terminal” at SFO.
The accompanying cover letter invited recipients “to participate in the selection process
for the Post-Security Master Retail/Duty-Free Concession (this ‘Concession
5
Opportunity’),” described as an “outstanding business opportunity, comprised of
twenty-five (25) locations, expand[ing] over 51,900 square feet of concession space in
the New International Terminal, which is scheduled to open in May 2000.” The
“locations” or “facilities,” would including four duty-free retail shops comprising about
half of the square footage involved, and about twenty other stores selling goods ranging
from jewelry and watches to news and sundries.
Details were included in a proposed form of master agreement, which was
comprised of a master lease (entitled, “Lease Agreement for Post-Security Master
Retail/Duty-Free Concession in the New International Terminal Building at San
Francisco International Airport”) and various attachments. Among its principal terms,
the “Permitted Use” was for “[t]he display and retail sale of the merchandise described on
the attached Exhibit B,” which listed the spaces to be leased by number and described the
types of merchandise that could be sold at each. Merchandise other than duty-free items
would be sold “on a non-exclusive basis,” but the winning bidder’s right to sell duty-free
merchandise at SFO would be exclusive. The term of the agreement would be ten years.
The only substantive term open for competitive bidding was price, structured as a
minimum guaranteed payment to SFO. Under the terms of the request for proposal (and
accompanying proposed master lease), the winning bidder would be required to pay
“rent” consisting of the greater of a Minimum Annual Guarantee (or “MAG”) and the
sum of various tiered percentages of gross revenues from retail sales. The minimum bid
was set at a minimum annual guarantee of $25 million. And the bid form, which stated
the bid was submitted “as and for compensation for the privilege of and permission to
operate the Concession Opportunity,” contained just a single substantive blank for
prospective bidders to fill out: the amount of the first year’s minimum annual guarantee.
Assuming the proposer satisfied minimum qualifications for operating the business and
provided satisfactory plans, SFO anticipated the concession opportunity would be
awarded to the proposer who bid the highest amount for the MAG.
6
DFS, which had significant experience operating duty-free and other retail
concessions at airports, including SFO, was the only qualifying bidder.4
It bid $1.1
million above asking, offering a MAG of $26.1 million.
In 1999, SFO accepted DFS’s proposal, which its Deputy Director for Business
and Finance described as “the largest merchandising contract ever let in the Airport’s
history.” Thereafter, SFO and DFS executed the final Lease Agreement for Post-Security
Master Retail/Duty-Free Concession in the New International Terminal Building at San
Francisco International Airport (the Agreement). Under the Agreement, DFS would
lease 29 retail facilities comprising about 58,000 square feet of space in the new IT, of
which about 25,000 square feet would provide duty-free merchandise.5 Consistent with
the RFP, under the Agreement the “Permitted Use” of the leased space was described as
“[t]he display and sale of [specified] merchandise,” including duty-free merchandise, and
DFS’s rights to sell duty-free/in bond merchandise were exclusive at the Airport.
Consistent with the bidding documents, DFS agreed to pay monetary
consideration structured as a minimum annual guaranteed amount, or if higher, the sum
of various tiered percentages of its gross revenues. Specifically, it agreed to pay “the
greater of the Minimum Annual Guarantee . . . and the sum of the following [percentages
of gross revenues].”6 The MAG was set at $26.1 million for the first year, subject to

4
In addition to requiring bidders to submit a substantive, sealed bid concerning
“the annual rent structure for this Concession Opportunity,” the RFP required bidders to
submit a second set of materials demonstrating they met SFO’s minimum qualifications
and that their proposal for meeting SFO’s other requirements (in terms of design,
construction and other details such as using disadvantaged minority enterprises) was
acceptable.
5
Of this, two retail outlets covering about 4,600 square feet had been added to the
Agreement after the concession was awarded to DFS at the request of SFO, after other
bids to operate those outlets had fallen through for other reasons. The MAG was not
increased when these outlets were added.
6 For sales other than duty-free sales, the percentages were 12 percent of gross
revenues up to $50 million, 14 percent of gross revenues from $50 to $100 million, and
16 percent of gross revenues over $100 million. For duty-free sales, the thresholds were
the same but the percentages were higher: 15, 20 and 25 percent, respectively.
7
annual adjustments for increases in the consumer price index and the number of departing
passengers (referred to as “enplanements”).
In recognition of the fact that the IT “may be opened in phases,” if fewer than 20
arrival/departure gates were available for use at the “Rent Commencement Date,” the
MAG would be reduced in proportion to the number of gates not yet operating.
DFS and SFO amended the Agreement several times, in ways for the most part not
pertinent here. After the terrorist attacks on September 11, 2001, there were several
amendments that suspended and then partially reinstated the MAG for a limited time, to
alleviate the economic hardship occasioned by the decline in air travel. For purposes of
implementing those temporary reductions, the amendments allocated 90 percent of the
MAG to duty-free “goods” and 10 percent to duty-paid “goods” (and specified different
terms for reinstating the full amount of the MAG as to each).
The Agreement was set to expire in 2010, subject to certain options to extend.
Near the end of that term, DFS exercised an option to extend the Agreement by five
years, and SFO exercised two one-year options to extend. The MAG to which the parties
agreed going forward was $26.4 million.
Under the Agreement with amendments, DFS currently leases more than 59,000
square feet of space and has a concession to sell duty-free and duty-paid merchandise on
a retail basis at SFO. About 27,000 square feet of this space is dedicated to DFS’s sale of
duty-free products. Of the remaining space, DFS operates some duty-paid retail outlets
and subleases others to a mix of retail tenants. At no time did DFS’s gross revenues ever
reach levels at which it was required to pay more than the MAG.7
The extension of the Agreement triggered the Assessor’s reassessment of DFS’s
property interest at SFO. As noted, for purposes of the reassessment, the Assessor valued
DFS’s possessory interest in the leased properties using the income approach. The

7
Indeed, for the first six years the Agreement was in effect prior to the
extensions, DFS was not required to pay the full MAG or, in some years, any MAG at all
because of the dramatic decline in international travel and corresponding decline in sales
in the wake of September 11, 2001.
8
parties agree this was an appropriate methodology. However, what is in dispute is the
income stream used by the Assessor in applying that methodology, which was the full
amount of the MAG (for 2011 this was $26.4 million). Capitalizing that entire amount,
and after deducting certain expenses and applying a discount factor, the Assessor arrived
at a present value for the possessory interest of $59 million.
II.
Assessment Appeals Board Proceedings
DFS appealed the Assessor’s determination to the San Mateo County Assessment
Appeals Board (Board), and the matter proceeded to a four-day hearing. The crux of
DFS’s challenge was its theory that the MAG compensated SFO not only for DFS’s use
of the space at the airport but also for its exclusive right to operate duty-free concessions
there. By failing to deduct the fair market value of the latter right from its valuation, DFS
contended, the Assessor’s valuation violated sections 110, subdivision (d) and 212
subdivision (c), which exempt intangible assets and right from property taxation.
A. DFS’s Evidence
1. Lyons
Joe Lyons, long-time employee and current Vice President of Business
Development for DFS, was responsible for negotiating DFS’s concession agreements and
participated in the submission of DFS’s winning bid at SFO.
Lyons testified that DFS operates retail concessions, both duty-free and non-dutyfree
(or duty-paid), at a number of airports including in San Francisco, Los Angeles,
Honolulu and New York (JFK). He explained that duty-free concessions are operated
under the auspices of the U.S. Customs Service (Customs) and the federal Bureau of
Alcohol, Tobacco and Firearms (ATF). The business consists of selling merchandise that
is free of duty and taxes to passengers departing on direct international flights to overseas
destinations. The business involves purchasing merchandise from overseas that is
entered into the United States “in-bond.” Customs regulations require DFS to control the
merchandise and keep it secure and to provide documentation of sales. A duty-free
9
business must operate within an airport, where the merchandise is sold or delivered to
departing passengers.
The IT at SFO has two concourses, each with food and beverage businesses, retail
services, retail products, and each with two duty-free areas. DFS operates the duty-free
and some of the duty-paid retail spaces, and its subtenants operate the other duty-paid
retail space. Food and beverage concessions are operated by others.
Lyons testified that airports that have robust international traffic generally have
duty-free concessions. Some airports in North America do not have a single duty-free
provider, but have multiple duty-free operators with concessions at different terminals
(i.e., Houston, Chicago O’Hare, New Jersey and New York’s Port Authority). However,
Lyon was not aware of any duty-free concession in the United States that does not
operate exclusively in the terminal it is in.
Lyons testified that in determining what to bid on a duty-free concession, DFS
considers a number of factors but that exclusivity is a “big part” of what DFS is paying
for. Without it, he testified, DFS would not be able to make enough to pay the MAG.
Lyons testified the MAG, originally set at $26.1 million but later increased to
$26.4 million, was compensation for more than simply rental of the space. According to
Lyons, the MAG was paid both for the use of the space at the airport and for the right and
privilege to operate the business, including the exclusive duty-free concession. Lyons
also testified that when SFO and DFS extended the lease in 2010, SFO expected DFS
would pay the MAG and not percentage rent over the seven-year term of the extension.
SFO was able to raise the MAG to $26.4 million even though it understood that the
market rate MAG it could obtain if it rebid the duty-free and duty-paid lease was only
$21,940,000.8

8 The amendment that extended the lease also required DFS to invest at least $2.4
million in facility renovations and construction during fiscal year 2011. This included
construction of one new duty-free store in Terminal 3.
10
2. Runde
Timothy Runde, a commercial real estate appraiser, prepared an analysis of the
value of DFS’s possessory interest based on rental rates of comparable properties.
Relying on other leases at SFO (both within the IT and in other terminals), and high-end
retail leases in the Union Square and the Fisherman’s Wharf areas of San Francisco, he
calculated that the total market rent for all DFS’s leased space at SFO was approximately
$14 million. Using that figure in an income analysis, he concluded that the fair market
value of DFS’s possessory interest at SFO was approximately $30,660,000, which was
approximately one-half of the value the Assessor had ascribed to it.
3. O’Connor
DFS also proffered the opinion of Mary O’Connor, an expert in valuing business
enterprises and intangible assets, who valued DFS’s exclusive right to engage in dutyfree
sales at SFO during the relevant period at approximately $28.6 million.9 Deducting
that amount for the entire capitalized MAG, she estimated the rental value of just the
physical property at SFO, exclusive of DFS’s intangible franchise right, at approximately
$15.4 million.
As part of her approach, O’Connor determined a separate stream of revenue
attributable to the exclusive right to operate the duty-free concession at SFO. She
testified that the right to do business offering duty-free goods with exclusivity is very
attractive. One indication of its value here was that DFS’s duty-free sales represented
about 70 percent of its total sales revenue in 2010 ($70 million of about $100 million in
total revenue) and its duty-paid sales only 30 percent (about $30 million), even though
the square footage devoted to the two categories of retail operations was approximately
equal.
O’Connor also testified about the importance of the right of exclusivity for
businesses such as DFS. She explained that the business model for a duty-free business

9
O’Connor’s methodology for valuing the duty-free concession involved
comparing DFS’s fee for duty-free sales with its fee for duty-paid sales. We omit the
details.
11
does not depend on the seller’s brand name, but rather on the brand names of its
merchandise and the lack of duties or taxes. Without exclusivity, she testified, there
would be no way to differentiate one duty-free seller from another, with the result that
there would be pure price competition and the business with the highest costs would drop
out. Exclusivity is thus essential to the business, she opined, and DFS is willing to pay
extra money for it and would have no interest in being at SFO without it. At other
airports too, she testified, “there’s a substantial premium [in concession fees] for doing
duty-free businesses.”
B. The Assessor’s Evidence
1. Tharayil
To rebut the analysis of DFS’s commercial real estate appraiser, Runde, the Board
called Alex Tharayil, a long-time former appraiser from the San Francisco City and
County Assessor’s Office.
Tharayil acknowledged that the right to sell duty-free is a “big right” but criticized
Runde’s valuation as “totally invalid.” Principally, Tharayil disagreed with Runde’s
choice of comparable properties and his failure to make adjustments for various attributes
of those other properties, including their lack of the right to sell duty-free. He also
faulted Runde for not taking into account that the rights SFO gave DFS are a
government-created, legally permitted use. In Tharayil’s view, the rights SFO gave DFS
to sell duty-free are a property right, that is, a right to occupy space, because they were
given by a public entity.
2. Andersen
The Assessor also called the person who performed the challenged assessment in
question, Stephen Andersen, a senior appraiser in the Assessor’s office.
Andersen explained his valuation methodology. As noted, he testified that he used
the income method. He testified that in deciding which of the Agreement’s two
documented income streams to use in his analysis, he chose the MAG rather than the
12
percentage-based tiered rents because the MAG was guaranteed revenue to the airport.
10
And he treated the MAG as economic rent for the property. Andersen assessed the
possessory interest at its highest and best uses, which he testified were duty-free retail,
duty-paid retail and storage, all distinct permitted uses. Using leases at several other
international airports as comparables (both duty-free and duty-paid sales and rents), he
concluded that DFS’s rent at SFO was market rate for a similar location.11
Andersen recognized that payments to a public entity that are not made as
consideration for real property must be excluded from economic rent but, based on his
interpretation of the Agreement, he considered the MAG as a payment solely for rights in
real property. In his view, it represented the minimal annual guarantee SFO would accept
for DFS’s possessory interest rights to occupy and use the real property only, and that any
other rights under the Agreement, including the right to operate a retail business, were
compensated by other consideration under the Agreement.
In particular, Andersen believed the percentage rents constituted consideration for
DFS’s exclusive concession right. He took this view even though he acknowledged the
Agreement did not make exclusivity contingent on DFS exceeding the MAG (and thereby
paying any percentage rents), and even though the non-duty-free retail spaces were also
subject to a percentage rent structure. And he testified, based on “logic,” that the value of
DFS’s exclusive right to sell duty-free was not due to exclusivity but, rather, the right to
sell duty-free.
C. DFS’s Rebuttal Evidence
On rebuttal, DFS’s board member Lyons testified that airports decide whether to
have duty-free concessions at all, and whether to make them exclusive. He also testified

10
With storage space included, the MAG was $26,589,983. The storage space
accounted for $189,000. DFS only capitalized the master lease and not the storage space.
11
Like Tharayil, Andersen also disagreed with several of Runde’s choices of
comparable properties for various reasons (in particular, Union Square and Fisherman’s
Wharf).
13
that exclusivity of the duty-free concession at SFO was a “major part” in DFS bidding the
amount it did, and that without it DFS would have bid a lower MAG.
D. The Board’s Decision
The Board denied DFS’s appeal and affirmed the Assessor’s determination. It
concluded that the MAG was an appropriate measure of economic rent and was
appropriately used.
In reaching this conclusion, it interpreted the MAG as consideration solely for the
right to occupy space and not for any additional rights. That interpretation was based on
certain provisions of the Agreement tying the MAG to the amount of leased space (for
example, option provisions that allow SFO to reduce the size of the premises with a
proportionate reduction in the MAG).
The Board did not find that the exclusivity of DFS’s right to sell duty-free goods
at SFO had no value. However, the record, in its view, did not indicate that its value was
“embedded within the MAG paid by DFS.” The Board reasoned that unlike provisions
linking the MAG to square footage of the premises, there were no provisions
“establish[ing] a similar relationship between the MAG and exclusivity.” The Board also
opined that the fact that DFS did not attempt during negotiations for the Agreement or the
extensions of the Agreement “to assign or calculate the value of exclusivity” indicated
that the MAG did not include a payment for exclusivity. It hypothesized that “SFO might
reasonably [have] decide[d]” not to require bidders to pay for the entire value of
exclusivity, because without exclusivity the business would fail which would not be in
the interest of airport authorities, and that DFS may have compensated SFO for
exclusivity in other ways under the Agreement, such as by agreeing to act as a landlord to
subtenants, to restrict its pricing and merchandise in various ways, to pay for
improvements or by bringing its experience to bear.
For reasons not pertinent here, the Board also rejected O’Connor’s valuation of
DFS’s intangible franchise operating rights, rejected Runde’s analysis of comparable
rents, and considered the Assessor’s sales and rent figures at other airports to be more
comparable.
14
E. Refund Action
DFS challenged the Board’s decision by filing a complaint for refund in the San
Mateo County Superior Court. That court affirmed the Board’s decision and issued
judgment for the County. Because the Board and the Assessor are both agencies of the
County and are aligned in their position, hereafter we will refer to them collectively as
“the County.”
DISCUSSION
The parties agree that the income capitalization method is an appropriate valuation
method in this case and, furthermore, that it was appropriate to use the minimum annual
guaranteed amount of “rent” (i.e., the MAG) to determine DFS’s income from the
property. The primary issue is whether the income to be capitalized should be that entire
amount of monetary consideration reflected in the Agreement, or instead that amount
reduced by the value of DFS’s exclusive right to sell duty-free goods, which the parties
agree is an intangible interest.
DFS contends the Assessor violated the prohibition on taxing its intangible
exclusive right to sell duty-free goods at SFO by failing to segregate the portion of the
MAG it paid SFO for that intangible right from the portion it paid for the use of the real
property at SFO. The County, on the other hand, contends that capitalizing the entire
MAG was proper under section 110, subdivision (e), because doing so merely assumed
the presence of intangible rights that were necessary to put the property to its highest and
best use, i.e., selling duty-free merchandise. In the alternative, it argues that the exclusive
right to sell duty-free goods at SFO, while intangible, is taxable under section 110,
subdivision (f) as an “attribute of the real property” DFS leased from SFO.
These issues, going to the validity of the assessor’s valuation method, present
questions of law we review de novo.12
(See Elk Hills, supra, 57 Cal.4th at p. 606; accord,
GTE Sprint Communications Corp. v. County of Alameda (1994) 26 Cal.App.4th 992,

12
The County concedes this in its brief, acknowledging that “[w]hether an
intangible asset has been included in an assessment is a question of law.”
15
1001; SHC Half Moon Bay, LLC v. County of San Mateo (2014) 226 Cal.App.4th 471,
476, 488–489 (SHC).) Were any facts in dispute, we would apply the substantial
evidence standard. (See Elk Hills, at p. 606.) However, the relevant facts here are
undisputed.
I.
The Burden of Proof
Before turning to substance, we first address a procedural matter to which the
County devotes much of its brief, namely the argument that DFS failed to satisfy its
burden of proof to show the assessed value was erroneous. Specifically, the County
contends DFS was required to, but did not, establish the fair market value of its
possessory interest and the value of the exclusive right to sell duty-free goods at SFO. It
criticizes the evidence DFS proffered concerning the value of its possessory and
intangible rights, and argues the Board had discretion to reject those valuations.
These arguments are premised on a misunderstanding of the law. To be sure, it
was the taxpayer’s burden to show the Assessor erred in its valuation by including the
value of intangibles in its assessment. (SHC, supra, 226 Cal.App.4th at pp. 492–493.)
As stated in Elk Hills, the taxpayer must “put forth credible evidence that the fair market
value of those assets has been improperly subsumed in the valuation.” (Elk Hills, supra,
57 Cal.4th at p. 615.) But this does not mean DFS had to satisfy the Board that its own
valuations of the possessory and intangible interests were correct. “The issue we must
resolve is not whether [the taxpayer’s] calculations can be approved, or even whether its
methodology is acceptable, but whether the County’s approach is valid.” (Service
America Corp. v. County of San Diego (1993) 15 Cal.App.4th 1232, 1237 (Service
America).) As in Service America, this question rests on whether the method used by the
Assessor, i.e., capitalizing the entire income stream payable to the City under the
concession Agreement, is correct, a question the court treated as a legal one because the
facts were not in dispute. (See id. at p. 1235.) The trial court in Service America ruled
that the assessor’s methodology was incorrect, but “[w]ith commendable deference to the
administrative board, the judge admitted he was ‘not prepared to declare the correct
16
methodology,’ but issued a writ of mandamus to the Board requiring it to ‘set aside its
decision . . . to reconsider its action . . . and to take any further action specifically
enjoined on it by law.’ ” (Id. at p. 1234.) The appellate court agreed with this approach.
(Id. at pp. 1241–1242.)
So here, while the parties argue about whether DFS’s valuations were correct and
whether the Board erred in rejecting them, that is not the primary issue before this court.
Rather, the primary question is whether the County’s approach is valid. On that issue, as
we next explain, DFS met its burden of proof to show the County utilized a legally
erroneous methodology. It is undisputed that the Assessor capitalized the entire income
stream payable to SFO under the Agreement and assumed it represented rent for the
possessory interest alone. Yet DFS established (and the County does not dispute) that the
exclusive concession right the Agreement also conferred on DFS was valuable, and the
Assessor made no attempt to remove that value from that income stream before
capitalizing it. As we next explain, that approach was legally erroneous. The County’s
argument that DFS additionally had to prove the actual value of its possessory and
intangible interests to the satisfaction of the Board, is without merit as Service America
plainly demonstrates.13
II.
Including the Value of the Exclusive Duty-Free Concession in the Assessor’s Income
Stream Analysis Did Not Merely “Assume Its Presence” for Purposes of Fair Market
Valuation.
A. Legal Principles
Not all intangible rights must be deducted under an income approach to valuation.
The leading authority on the legal issue presented here is our Supreme Court’s decision in
Elk Hills, which harmonized subdivisions (d) and (e) of section 110 as “contain[ing]
nonconflicting principles that must be applied together.” (Elk Hills, supra, 57 Cal.4th at

13 Because we reject the County’s argument that DFS was required to prove the
value of its intangible concession interest and its possessory interest, we do not address
its contentions or DFS’s response regarding whether the Board correctly rejected DFS’s
valuation evidence.

p. 610.) It explained that “although assessors may assume the presence of intangibles
when considering the income stream derived from taxable property that is put to
beneficial or productive use (§ 110[, subd.] (e)), the value of intangibles that directly
enhance that income stream cannot be subsumed in the valuation of taxable property
(§110[, subd.] (d)(1)), and must be deducted from the unit prior to assessment
(§ 110[, subd.] (d)(2)).” (Id. at p. 618, italics added.) The court interpreted section 110
as requiring the assessing entity conducting an income analysis to deduct the fair market
value of intangible assets with “a direct contribution to the going concern value of the
business,” including “intangible assets like the goodwill of a business, customer base, and
favorable franchise terms or operating contracts.” (Elk Hills, at pp. 618–619, italics
added.) By contrast, the court explained, intangible rights that “merely allow for the
taxable property to generate income when put to its beneficial or productive use” have
only an “indirect” contribution to income stream, and therefore warrant no deduction.
(Ibid.)
At issue in Elk Hills was the valuation of a powerplant. Judged by the standard
quoted above, the court held that the value attributable to environmental credits the
powerplant was legally required to purchase in order to operate (emission reduction
credits, or ERCs) was not required to be deducted from the income stream of the power
plant. The sole purpose of the ERCs, it explained, “is to enable the taxable property in
question to function and produce income as a powerplant, thereby enhancing the value of
that property.” (Elk Hills, supra, 57 Cal.4th at p. 619.) The taxpayer made “no credible
showing that there is a separate stream of income related to enterprise activity or even a
separate stream of income at all that is attributable to the ERCs in this case.” (Id. at
p. 602.) There was thus no indication the State Board of Equalization did anything other
than “ ‘assum[e] [the ERCs] presence’ in order to tax the property in question as a fully
functioning powerplant.” (Id. at p. 619.)
By contrast, the principle that a taxing agency using the income approach must
deduct the value of “intangible assets like . . . favorable franchise terms or operating
contracts” (Elk Hills, supra, 57 Cal.4th at pp. 618–619) is reflected in two earlier cases
18
the court cited with approval, Service America, supra, 15 Cal.App.4th 1232 and County
of Los Angeles v. County of Los Angeles Assessment Appeals Bd. (1993) 13 Cal.App.4th
102 (County of Los Angeles). (See Elk Hills, at pp. 610–611.)
Service America concerned the valuation of an exclusive concession agreement to
sell food and beverages at a municipal sports stadium. (Service America, supra,
15 Cal.App.4th at p. 1236.) The concession fee the taxpayer paid for the exclusive
concession rights was based on a percentage of its gross sales. (Ibid.) In applying the
income method, the assessor capitalized the entire amount of the estimated concession
fee the taxpayer was projected to pay during the term of the agreement, on the
assumption the fee represented rent for its use and occupancy of the stadium. (Id. at
pp. 1236–1237.) The taxpayer challenged the assessment, claiming the concession fee
included “a substantial sum representing consideration for rights and interests other than
those associated with the occupancy or use of property.” (Id. at p. 1237.) Recognizing
there was “no accurate way of separating the portion of the concession fee related to the
use of property from the portion of the fee based on other considerations” (ibid.), the
appellate court nonetheless held that the assessor and the Board erred in capitalizing the
entire concession fee. While it recognized that “[s]ome portion of the profitability of
Service America’s operation can reasonably be attributable to the taxable property it
utilizes,” the court held that, “[o]n the other hand, the exclusive nature of Service
America’s concession agreement and its going-business value undoubtedly constitute a
major factor in its profitability” and that “[t]he County cannot overlook or ignore these
values, which are not taxable, when assessing value.” (Id. at pp. 1241–1242.) While it
did not determine what the assessed value should have been, it suggested that “some form
of ‘imputed’ value must be utilized by the assessor to determine a fair ‘rental’ value for
the property.” (Id. at p. 1242.) It recognized that property in the stadium would have
greater rental value than rental values associated with other kinds of properties, but
concluded, “Whatever imputed value is selected . . . will presumably not result in
complete utilization of the agreed $19 million valuation of the total enterprise.” (Ibid.)
19
Similarly, County of Los Angeles held that a tax assessor had erred in basing its
assessment of rental car companies’ interests at three Southern California airports on the
entire concession fees they paid, because encompassed within those fees were nontaxable
intangibles including the companies’ rights to do business at the airports. The
agreements between the rental car companies and the airports granted “both the right to
conduct a car rental business at the particular airport and the right to occupy and use
certain limited portions of it.” (County of Los Angeles, supra, 13 Cal.App.4th at p. 105.)
The assessor there had capitalized the companies’ entire concession fees, which were
measured as a percentage of their income from their airport area operations,
characterizing the payments as “rents” paid for the companies’ possessory interests at the
airports. (Id. at pp. 112–113.) Although the assessor was entitled to tax any possessory
interests created by the concession agreements, “[t]he further rights granted by the
agreements, to do business at the airports and their environs, are not possessory
interests. They are intangibles, not subject to property (possessory interest) tax.” (Id. at
p. 112, italics added.) The assessor had erred, the court held, because its method “fail[ed]
to differentiate between the possessory interests in question and the valuable but
intangible business opportunities for which the agreements provide and the concession
fees also pay.” (Id. at p. 113.)
As we next explain, although the facts of this case differ in some respects from
those in Service America and County of Los Angeles, the courts’ analyses in those cases
compel the same result here.
B. DFS’s Exclusive Duty-Free Concession Is a Valuable Right Under the
Parties’ Agreement.
DFS met its burden to prove that the exclusive duty-free concession rights it
enjoyed under the Agreement were valuable, a point we do not understand the County to
dispute. It is unnecessary to summarize all of the evidence in the record showing just
how lucrative a business opportunity this was, which was considerable.
14
Even the

14
This included not only Lyon’s testimony that DFS could not make enough
money to pay the MAG without the exclusive concession right and that exclusivity was a
20
deputy assessor who performed the valuation, Andersen, acknowledged the right to sell
duty-free is a “big right,” and although he testified (based on “logic”) the exclusivity
component added no value, the Board found otherwise. On appeal, the County does not
dispute the Board’s finding that the exclusive right has value. Thus, unlike the emission
reduction credits at issue in Elk Hills that were not directly related to the powerplant’s
enterprise activity, the purpose of the concession right to sell duty-free products at SFO,
and to do so without competition, is not solely “to enable the taxable property in question
to function and produce income.” (Elk Hills, supra, 57 Cal.4th at p. 619.) Rather, that
exclusive duty-free concession right directly contributed to DFS’s ability to operate its
business profitably.
That leaves only the question, then, whether this valuable right was a part of the
bundle of rights for which DFS bargained when it agreed to pay, and paid, the MAG.15 If
it was, then the Assessor erred by including its value in the income valuation. We
conclude it was.

major factor in its bid for the MAG. SFO’s offering prospectus compared historical sales
per square foot of duty-free goods, food and beverage sales, and other retail merchandise.
The revenue from duty-free sales was nine to ten times the revenue from the sale of food
and beverages on a per-square-foot basis, and three to four times the sales revenue from
duty-paid merchandise. Specifically, in the five years prior to 1999, duty-free sales at
SFO ranged from $4,117 to $5,997 per square foot as compared to $431 to $669 for food
and beverage sales, and $1,239 to $1,474 for sales of non-duty-free retail merchandise.
The parties submitted industry data about other international airports with duty-free
concessions for 2009, 2010 and 2011, from which similarly disparate sales per square
foot figures for duty-free and other types of concessions can be determined. Finally, DFS
introduced evidence that 70 percent of its SFO revenues were derived from its duty-free
concessions, even though those concessions occupied only about half of the space it
occupied there. The evidence also demonstrated that at SFO and other airports with dutyfree
concessions, significantly higher amounts were paid for duty-free concessions than
for other types of concessions.
15 The precise value of DFS’s exclusive concession right is disputed, and we do
not resolve that issue here. The Assessor and the Board rejected the only evidence
placing a value on that right, which was the opinion of DFS’s expert, O’Connor. On
remand, the Board may revisit this issue and, if it is appropriate, permit the parties to
submit additional evidence.
21
C. The Agreement Conveyed to DFS Both Tangible Property Rights and
Intangible Concession Rights, and the MAG Was Consideration for Both.
As the Board recognized, the issue of whether the MAG was consideration for the
exclusive franchise right turns on interpreting the Agreement. And the basic tenets of
contract interpretation are well established. “Interpretation of a contract consists of
ascertaining the meaning to be given to the expression of the parties.” (1 Witkin,
Summary of Cal. Law (11th ed. 2018) Contracts, § 764; see Civ. Code, § 1636.) “Where
the language of a contract is clear and not absurd, it will be followed.” (1 Witkin, supra,
§ 764.) We construe the contract as a whole, “so as to give effect to every part.” (Id.,
§ 769; Civ. Code, § 1641.) We accord the words of a contract their ordinary meaning
unless otherwise indicated. (1 Witkin, supra, § 768; Civ. Code, § 1644.) “ ‘A contract
may be explained by reference to the circumstances under which it was made, and the
matter to which it relates.’ ([Civ. Code, §] 1647.) ‘For the proper construction of an
instrument, the circumstances under which it was made, including the situation of the
subject of the instrument, and of the parties to it, may also be shown, so that the Judge be
placed in the position of those whose language he is to interpret.’ ([Code Civ. Proc.,
§] 1860.)” (1 Witkin, supra, § 771.)
As DFS points out (and the County does not dispute), contract interpretation is an
issue of law, which we review de novo, including where undisputed parol evidence sheds
light on the parties’ intent. (Parsons v. Bristol Development Co. (1965) 62 Cal.2d 861,
865 [“It is . . . solely a judicial function to interpret a written instrument unless the
interpretation turns on the credibility of extrinsic evidence”].)
Starting first by examining the words of the Agreement, the Agreement’s actual
language is inconclusive as to whether the MAG included compensation for the exclusive
right to sell merchandise duty-free or whether, as found by the Board, it was solely
compensation for DFS’s possessory interest.16 The Agreement does not expressly state

16 In considering this question we disregard all titles and captions, because the
parties expressly agreed they were irrelevant for purposes of interpreting the Agreement
and not intended to carry substantive meaning.
22
one way or the other. And the Board’s analysis of the Agreement’s plain language was
flawed, because it focused on provisions that on their face shed no light on this
question.
17 The only words that arguably support the latter interpretation is the
Agreement’s characterization of DFS’s monetary payments to SFO as “rent.” In
pertinent part, Paragraph 4.3 states that DFS “shall pay, as rent for the Premises,
estimated monthly Base Rent.” “Base Rent” is then defined as the greater of the MAG or
specified tiered percentage rents. According this terminology its ordinary meaning
(Civ. Code, § 1644), this language in isolation could be understood to mean that Base
Rent, including the MAG, was consideration solely for DFS’s use and occupancy of the
space. But for several reasons, a different meaning other than its ordinary one is
indicated. (Ibid.) Such a cramped construction is defied by the entire commercial

17 In concluding that the MAG was economic rent for the possessory interest
alone, the Board relied heavily on two provisions that link the MAG to the amount of
space leased: section 1.2, governing relocations, which provides that expansions or
reductions of more than 10 percent of the premises occurring as part of a relocation
would result in a pro rata adjustment to the MAG based on the size of the replacement
premises; and section 2.2, which gave SFO two one-year options to extend the term of
the Agreement as to some (or all) facilities and provides that the MAG and the
percentage rent thresholds will be reduced pro rata based on any square footage that was
not retained. These provisions tying the amount of the MAG to square footage certainly
indicate the MAG was intended at least in part as compensation for the use and
occupancy of the leased space. They do not demonstrate, though, that the MAG was not
also consideration for the concession rights. On the contrary, the concession rights and
the amount of space leased were interdependent. The more space provided, the greater
the amount of merchandise DFS and its subtenants could display and, presumably, sell.
Thus, a reduction in space would affect the value not only of the possessory interest but
also the value of the exclusive concession rights.
The Board also relied on section 5.4(f), which caps the amount DFS may charge a
subtenant at the total amount it pays SFO for “the portion of the Premises subleased by
the subtenant,” and for the first year, at the pro rata amount of the MAG attributable to
the subtenant premises. This provision does not establish what was in fact charged by
DFS for the subleased space; rather it is a cap on what DFS could charge subtenants, the
obvious purpose of which was to prevent DFS from profiting on subleases by charging a
premium over what DFS was paying SFO for the same concession space.
23
context of this contract, including the parties’ later course of conduct, and would lead to
an absurd, illogical result.
In the first place, construing “rent” as meaning compensation solely for use and
occupancy, and not also compensation for the valuable exclusive concession right, is
internally inconsistent. That is because the Agreement characterizes both forms of
monetary compensation as rent: both the MAG, and the tiered percentages. Deputy
Assessor Andersen suggested in his testimony before the Board, and the County’s brief
on appeal similarly implies, that the tiered percentage compensation structure alone
provides compensation for the exclusive duty-free concession. But the term “rent”
cannot mean one thing as applied to the MAG, namely compensation for the possessory
interest, and quite another as applied to the alternative percentage-based compensation,
namely consideration for the concession. As used in this context, the term “rent” is just
synonymous with “monetary consideration.” The question is, for what?
The entire context of the bidding process, and the language the parties used to
describe it, demonstrate that DFS, in bidding the MAG that it did—a MAG that was $1.1
million above SFO’s minimum required figure—did not bid monetary compensation
solely to secure a retail space. It bid for the business opportunity at SFO, and the
possessory interest alone was not solely or even primarily what SFO advertised or DFS
bid on. Rather, the possessory interest was a necessary adjunct of the business
opportunity. Indeed, the commercial context shows that SFO did not seek a tenant but
rather a reliable business partner that could exploit the duty-free opportunities at the
airport to the parties’ mutual economic advantage. They were akin to partners in a joint
venture in which DFS would provide services and know-how, SFO would provide space
and both would profit from the opportunity. Simply put, and contrary to the County’s
portrayal, DFS’s role in this transaction was not that of a mere purveyor of goods, in
search of a suitable brick-and-mortar location to hawk its wares, and SFO was not merely
a landlord offering to lease space to the highest bidder.
Thus, in the documentation accompanying SFO’s invitation to bid, SFO repeatedly
described this opportunity not as a potential real estate transaction but as a “concession
24
opportunity” and an “outstanding business opportunity.” Further, there were the bidding
requirements, which reflected an overall principal concern not just with a tenant’s creditworthiness
but the bidder’s business acumen and ability to develop a financially viable,
economically profitable merchandising program.18 And then, of course, all these bidding
requirements culminated in the bid form itself, which stated that the bidder “submits this
bid as and for compensation for the privilege of and permission to operate the
Concession Opportunity.” (Italics added.) Finally, during the San Francisco Airport
Commission hearing at which DFS’s bid was approved, SFO’s deputy director of
business and finance described the Agreement as “the largest merchandising contract
ever let in the Airport’s history” and “the cornerstone of what will be a fabulous new
program.” All this undisputed extrinsic evidence concerning the bidding process makes
plain SFO’s understanding of what it was selling in exchange for the MAG: not a mere
possessory interest at the international terminal, but a valuable business opportunity from
which it expected to mutually profit.19
The terms of the Agreement confirm this. The Agreement conveys far more than
a possessory interest in SFO’s IT, and in doing so not only allows DFS to operate an

18 Chief among these was the requirement that bidders meet minimum
qualifications relating to their business and financial experience, including three years of
“experience in the ownership or management of a retail merchandise business (including
duty-free)” that had achieved gross revenues of at least $100 million per year. Bidders
also were required to “describe in detail the proposed retail concept for each facility and
how the concepts will complement the surrounding shops.” And SFO expressed interest
in participants’ ability “to deliver exciting local brand names and other high quality retail
and duty-free merchandise” and to “offer the most exciting blend of design and concept
execution for the attraction of optimum sales from Airport passengers.” SFO required a
minimum investment of $7.8 million in improvements to the premises, and bidders were
required to describe a staffing plan, cash control system, delivery schedule and logistics,
and customer service philosophy and program.
19
SFO would profit greatly from the MAG itself, which guaranteed a per-squarefoot
rate much higher than other kinds of concessionaires paid for similar space (see
footnote 14, ante, pages 19–20) and it would profit still further from percentage rents if
DFS’s revenues reached the threshold levels triggering the obligation to pay percentage
rents.
25
exclusive duty-free concession there but requires DFS to carry out that business in a
manner that maximizes SFO’s own bottom-line. This is evident from the Agreement’s
very first page, where its recitals characterize DFS’s role as that of a service provider, not
a tenant: it states that DFS “desire[d] to provide and operate the service described in the
Permitted Use at the Airport and [SFO] ha[d] determined such service would be an
accommodation and convenience for airline passengers and the public.” (Italics added.)
Next, Part 3 of the Agreement obligates DFS to operate its business at SFO “so as to
maximize Gross Revenues,” and it regulates certain aspects of retail operations in a
manner consistent with that goal.20 The reason for these requirements, of course, is
because the higher the gross revenues DFS achieved, the more “rent” SFO could expect
in return for this “concession opportunity,” as SFO repeatedly described it. Finally,
section 4.10 of the Agreement proportionately reduces the MAG if delays in completing
construction or factors resulted in fewer functioning arrival/departure gates than planned
at the time DFS’s rent obligation commences. This provision reflects that the MAG was
understood by the parties as consideration for the profitable business opportunity the
Agreement was providing; if unplanned circumstances reduced the profitability of that
opportunity, the MAG would be commensurately reduced.
To construe DFS’s monetary bid as including no compensation for the valuable
exclusive concession rights it obtained makes no economic sense, from either party’s
perspective. This is evident from the entire focus of the bidding process, and from
Lyon’s uncontradicted testimony that without this exclusive right DFS would not have
bid $26.4 million and could not have afforded to pay the MAG. It is also evident from
the undisputed evidence demonstrating that duty-free concessions are highly profitable

20 For example, it includes the requirement DFS conduct business in a first-class,
safe and efficient manner, carry a wide range of top quality merchandise and employ
sufficient and experienced staff. It also requires DFS to use at least 85 percent of the
Premises for display and sale of retail merchandise and requires it to keep the Premises
open for 16 hours every day and to charge prices comparable to those found in DFS’s
catalog, if any, and at its other retail shops or a local comparable retail shop.
26
and highly valued, and that entities that acquire duty-free concession rights at airports pay
significantly more for them than they or others are willing to pay for space used for other
kinds of concessions. (See footnote 14 and accompanying text, ante, pages 19–20.) SFO
had every incentive to extract through the MAG as much as it could get for the entire
opportunity, including the exclusive concession right; to have charged only what it could
get merely as rent for the physical space would be to leave serious money on the table.
Conversely, DFS had every incentive to offer serious money to try to win the concession,
which it did when it offered a sizable MAG ($1.1 million above the minimum required
bid).
Finally, two subsequent events confirm the parties’ understanding that the MAG
did not compensate SFO solely for the use of physical space. One is the amendment that
changed the MAG temporarily in the wake of 9/11. The parties recited in that
amendment that because of the September 11, 2001 terrorist attacks and their
“extraordinary and unexpected effects on travel worldwide,” “many of the Airport’s
concession tenants have represented that they are unable to conduct their businesses
under the existing terms of their respective Airport leases.” As part of a support program
for its concession tenants, SFO amended the Agreement to temporarily suspend the MAG
on all sales. DFS was instead required to pay percentage rent, but the thresholds for
percentage-based rent on duty-free sales were reduced. The amendment further provided
for reinstatement of “the MAG applicable to duty-free goods,” which it defined as
90 percent of the MAG, by the earlier of a specified date or once DFS had achieved $5
million in monthly gross revenues on duty-free sales for two consecutive months. By
expressly referring to “the MAG applicable to duty-free goods,” the amendment’s plain
language demonstrates the parties understood that some portion of the MAG, at least, was
intended as compensation for the right not to occupy physical space but to sell duty-free
goods. And the same is true in substance: by tying the suspension of the MAG to the
decline in air travel and the associated decline in the profitability of DFS’s businesses,
the amendment reflects the parties’ understanding that the MAG was compensation for
the opportunity “to conduct [its] business[],” because favorable business conditions had
27
been negatively impacted by the events of September 11. Similarly, by tying the
reinstatement of the duty-free portion of the MAG to DFS achieving a threshold level of
success on its duty-free sales (i.e., the 90 percent of the MAG the amendment attributed
to the duty-free concession), the amendment reflects the parties’ understanding that the
MAG was consideration, in no small part, for the duty-free concession rights DFS
acquired under the Agreement. In short, when the concession right was devalued by the
events of September 11, DFS was given a reprieve from paying the MAG
notwithstanding its continued use and occupancy of the space in the IT. The concession
opportunity was worth less not because the size or quality of the space had changed, but
because of external events that interfered with DFS’s ability to successfully operate its
concessions.
Second, there is the uncontradicted evidence that in late 2009, and again in early
2010, when DFS and SFO exercised options to extend the Agreement by a total of seven
years, it had become clear that the MAG was so high that it was unlikely the percentage
rents would ever to come into play. Whatever may have been SFO’s expectation when
the Agreement was first entered in 1999, by the time of those extensions SFO expected—
based on its projections of DFS’s gross sales—that DFS would not likely reach the sales
thresholds required to trigger the percentage rents and would pay only the MAG (which
had been adjusted upward to $26.4 million). This fact, that SFO expected the MAG to
serve as the entire monetary consideration, makes it implausible to believe it was
consideration only for the use of the space. Even if we accepted the County’s assertion
that only the percentage rents were intended as consideration for the concession rights at
the outset, which we do not, SFO’s expectation by the time of the extensions that
percentage rents would never be triggered would mean it expected no monetary
consideration for the concession rights. In view of the terms of Agreement and the
circumstances in which it was entered, we cannot accept that premise.
Finally, the Board reasoned that either SFO chose not to demand any
compensation for the exclusive right to sell duty-free goods, or that the consideration it
accepted could have been other provisions of the Agreements (such as limitations on the
28
types of goods DFS could sell or its management of the various subleases). There is no
extrinsic evidence that any of those other terms had significant, material value, however,
or that they factored at all in the formulation of DFS’s bid or in SFO’s consideration of it.
The Board’s interpretation was speculative, commercially unreasonable, and inconsistent
with the evidence we have just discussed. On this record, we conclude as a matter of law
that the MAG was bid and accepted as consideration for both DFS’s possessory interest
and its exclusive concession right.
D. Analysis
In light of that conclusion, the Assessor’s error here in capitalizing the full amount
of the MAG is similar to the error made in Service America, where the assessor
capitalized the full amount of the concession fee the taxpayer paid for the privilege of
operating its exclusive food and beverage concession rather than impute a lower
economic rent, because the fee also encompassed consideration for intangible business
opportunities.
The County argues Service America is distinguishable, because what the assessor
“did wrong” in that case “is that it used the corporation’s gross income in estimating the
market rent for the property,” by “looking at past sales of the corporation and us[ing] a
percentage of those gross sales to determine market rent.” According to the County, “the
[a]ssessor’s error was not in using the contract rent to capitalize under the income
method, but in imputing a contract rent that was based on the gross revenues of the
taxpayer.” “The use of gross sales was key to the court’s decision in Service America
because it necessarily captured the exclusivity component because it relied on the
profitability of the corporation.”
We disagree. The assessor’s error in Service America was in assuming that the
entire concession fee represented compensation for rent. As the court put it, “[t]he
dilemma . . . is that there is no accurate way of separating the portion of the concession
fee related to the use of property from the portion of the fee based on other
considerations.” (Service America, supra, 15 Cal.App.4th at p. 1237.) Some of those
29
other considerations have no bearing here.21
But one is directly pertinent: “the exclusive
nature of its concession grant.” (Id. at p. 1238.) There was undisputed evidence that the
prices charged to stadium patrons, who had no alternative source of food or drink, were
30 percent higher than would be charged under ordinary circumstances. (Ibid.) The
court reasoned, “[o]ne could conclude, therefore, that the basis for [the taxpayer’s]
willingness to pay a high concession fee does not relate to its right to use property, but
rather depends upon its purchase of an exclusive sales prerogative—clearly an intangible
right or benefit.” (Ibid., italics added.)
The same is true here. The MAG, rather than percentage rents, is the price DFS
paid for the bundle of rights it received from SFO. The evidence was undisputed that
exclusivity was key to its duty-free operation. With the exclusive right, DFS could
operate a highly profitable business. Without exclusivity and with competition, it could
not. “One could conclude, therefore, that the basis for [DFS’s] willingness to pay a high
concession fee,” here the $26.4 million MAG, “depends upon its purchase of an exclusive
sales prerogative,” which as noted in Service America, is “clearly an intangible right or
benefit.” And the foregoing analysis of the parties’ contract, in light of surrounding
circumstances, confirms that this is precisely what they did. Certainly, the MAG also
includes compensation for DFS’s right to use property. But here, as in Service America,
it was error for the Assessor and the Board to use the entire lease and concession fee as
the basis for valuation. (Service America, supra, 15 Cal.App.4th at p. 1240.)
Unlike in Service America, the taxpayer here does not contend that the Assessor’s
valuation improperly encompassed other intangibles (such as DFS’s experience operating

21 One problem was that the concessionaire’s gross sales “[had] very little
relationship to the use or occupancy of property” but, instead, were directly related to
stadium attendance which depended primarily on the success of the professional sports
teams that played there and the teams’ public relations efforts. (Service America, supra,
15 Cal.App.4th at p. 1237.) Another was that its revenue derived not only from its use of
the property but also from its value as a going business concern, with “competent
management, a large cadre of employees, and substantial experience and ‘goodwill’ in
the area of food service.” (Id. at p. 1238.)
30
duty-free concessions, its assembled workforce or its license from Customs or ATF), and
so we express no opinion on that subject. As in Service America, though, it is evident
here that the price DFS was willing to pay for the rights it acquired under the Agreement
was substantially greater than what it would have paid to rent space at SFO without the
exclusive right to sell duty-free merchandise. By capitalizing the entire price, the
Assessor directly taxed that exclusive right, which is forbidden by California law.22
As the courts have noted in these other cases, we do not hold that the Assessor
may not consider, in valuing DFS’s possessory interests at SFO, the attributes of the
property that make it favorable to the business DFS is doing and to the other retail
businesses that operate in the IT. (See County of Los Angeles, supra, 13 Cal.App.4th at
p. 113.) There is, as the County points out, a captive audience of international travelers
who arrive early to ensure they can clear security and thus have long “dwell times”23
during which they can shop. SFO is also, as both parties have acknowledged, a gateway
to travelers from Pacific Rim countries, many of whom have wealth and thus find the
premier shopping experience SFO and its IT concessionaires offer attractive. All of this
may be considered in valuing the possessory interests DFS has at SFO. That said,
whatever value the Assessor attributes to that possessory interest may not result in
employing as the income stream in its analysis the entire agreed-upon $26.4 million
valuation of the combined leasehold and concession package DFS acquired under the
Agreement.

22 The Assessor argued in the Board proceedings, and the County continues to
argue here, that the MAG represents “fair market rent” based on evidence of comparable
“duty-free leases at other international airports.” But the uses of these “leases” as
comparable possessory interests is based on the same flawed assumption the Assessor
made in valuing DFS’s interest: that the full amounts paid by the other duty-free
concessionaires was consideration only for their possessory rights and did not include any
consideration for their concession rights.
23 “Dwell time” refers to “[t]he period between passenger check-in and departure
time.”

III.
The Exclusive Duty-Free Concession Right Is Not a Taxable Attribute of the Real
Property.
Alternatively, the County suggests in passing that DFS’s exclusive right to sell
duty-free merchandise in locations SFO designated as duty-free is merely “an attribute of
the real property that the Board may consider when determining fair market value” under
section 110, subdivision (f). As noted, that provision states: “For purposes of
determining the ‘full cash value’ or ‘fair market value’ of real property, intangible
attributes of real property shall be reflected in the value of the real property. These
intangible attributes of real property include zoning, location, and other attributes that
relate directly to the real property involved.” (§ 110, subd. (f), italics added.) Citing
only to the statutory text, the County does not develop this argument or cite authority
supporting it. It simply asserts that SFO’s choice of the locations for duty-free shops is
“akin to . . . zoning.” We could hold that by failing to develop this argument the County
has forfeited it. (Eisenberg et al., Cal. Practice Guide: Civil Appeals and Writs (The
Rutter Group 2018) ¶ 9.21 [appellate court may treat as forfeited any issue that, although
raised in briefs,, is not supported by pertinent argument or citation of authority].)
However, DFS does not argue forfeiture and instead addresses the issue on the merits in
its reply brief. We will therefore address it on its merits.
The County’s construction fails to take account of, and is incompatible with, the
literal language of section 110, subdivision (d)(3) concerning exclusive concession rights
(quoted ante, pages 1–2). In relevant part, that provision defines the exclusive nature of a
concession, franchise or similar agreement as “an intangible asset that shall not enhance
the value of . . . real property.” (§ 110, subd. (d)(3), italics added.) Subdivision (f), by
contrast, mandates that “intangible attributes of real property shall be reflected in the
value of the real property.” (Italics added.) The only way to harmonize these provisions
is to interpret an “intangible attribute” of real property that must be included in a fair
market valuation as excluding those “intangible assets” that section 110,
32
subdivision (d)(3) places outside of bounds—including the exclusive nature of a
concession or franchise right.
Even if DFS’s duty-free concession right were not exclusive, moreover, our
conclusion would be the same because, again, this issue is directly controlled by Elk Hills
and the authorities it discusses. Rejecting the contention that the emission reduction
credits at issue there were “attributes of real property” within the meaning of
subdivision (f), the Supreme Court in Elk Hills explained that “ ‘[i]ntangible attributes of
real property do not include licenses, franchises, and other rights to do business that are
exercised in connection with the use of the real property.’ ” (Elk Hills, supra, 57 Cal.4th
at pp. 620–621.) It differentiated such rights to do business from intangibles such as
“location, zoning, view or architecture,” because they “ ‘relate to the real property only in
their connection with the business using it’ ” rather than entailing something that is an
“ ‘integral part of and effectively define[s]’ ” the real property. (Id. at pp. 620–621.)
And the case it quoted with approval on this point is illustrative: Shubat v. Sutter County
Assessment Appeals Bd. (1993) 13 Cal.App.4th 794 (Shubat), a case predating
section 110, subdivision (f)’s enactment, which held that a cable television company’s
franchise rights to do business as a cable company were not an “attribute” of its
possessory interest in the underlying real estate it occupied (i.e., the company’s public
rights of way to lay cable equipment in the streets). (Shubat, at pp. 803–804.)
These authorities are directly analogous. The right to sell duty-free goods at SFO
does not “relate directly to the real property” at SFO’s IT, is not “an integral part of [that
property]” and does not “effectively define it” any more than the right to sell cable
service to subscribers defined the cable company’s possessory interests in the public
rights-of-way in Shubat. On the contrary, it is a “right to do business that [is] exercised
in connection with the use of the real property” at SFO. Far from duty-free sales being
the only possible use of the concourses in the IT, those same concourses host many other
types of business in the very same area immediately adjacent to DFS’s duty-free shops.
In that post-security area, there also is an array of restaurants, a wine shop, a bookstore,
33
news and gift stores, a perfumery, and numerous other kinds of merchandisers, all of
which sell goods on a duty-paid basis.24

Finally, the County’s analogy to zoning is at odds not only with the law but also
logic. As DFS points out, the specification of certain areas as for duty-free retail is not an
exercise of government police power, it is the product of contractual agreement by two
sophisticated parties, each capable of negotiating mutually acceptable terms.
For these reasons, then, the County’s use of the entire MAG to assess the value of
DFS’s possessory interest cannot be justified on the theory that the intangible exclusive
right to sell duty-free goods is an attribute of DFS’s possessory interest in the real
property.
CONCLUSION
The Agreement and other evidence reflect that the exclusive concession to sell
duty-free merchandise at SFO was a significant factor in the MAG that DFS bid for the
rights conferred by the Agreement. The right to use the post-security space in the new IT
was also a significant component of that package. In valuing the possessory interests
DFS acquired, the County may not include the entire value of, and thereby directly tax,
the exclusive concession DFS also acquired. We do not mean to say the Board may not
assume the existence of the concession right in valuing the possessory interest. But, as
Elk Hills and other cases teach, assuming the presence of an intangible asset is not the
same as including the entire value of the intangible asset in the unit being taxed. (Elk
Hills, supra, 57 Cal.4th at p. 617 & fn. 10; see also GTE Sprint, supra, 26 Cal.App.4th at
pp. 1002–1004, 1008; Shubat, supra, 13 Cal.App.4th at p. 804.) To avoid directly taxing
DFS’s exclusive concession, the Board must either value that right and separate it from
the value of the possessory interest or impute a value to the possessory interest alone.

24 The documents relating to the RFP, which we have already described, make
plain that SFO desired not one kind of business to occupy that space, but a wide variety.
(See also Pub. Util. Code, § 21690.7 [directing governing bodies of publicly owned
airports to promote commerce and tourism in granting airport concessions by “securing a
diversity of airport services” and “avoiding wasteful duplication of such services”].)

(GTE Sprint, at p. 1007 [exclude value of intangible rights when assessing tangible
property]; Service America, supra, 15 Cal.App.4th at p. 1242 [use imputed value to
determine fair rental value for real property].)
Because the Board used the entire MAG as the income stream for its capitalization
analysis and failed to separate the portion of that MAG paid for the real property and
intangible interests, it is necessary to return this matter to the Board for a reassessment
hearing. The Board may reopen the record to allow the parties to present additional
evidence on valuation of the intangible and possessory interests at issue.
Because DFS and the County disagree as to whether the Board erred in largely
rejecting the expert testimony of DFS’s possessory interest expert, Runde, and that of its
intangible interest valuation expert, O’Connor, we make some observations that may
serve as guidance. Some of the criticisms leveled at Runde’s valuation related to the
difficulty of finding properties comparable to the relatively unusual property at issue
here. However, it can be difficult to value unusual or unique properties, and therefore
considering comparable values for properties that are not precisely similar may be
appropriate even if not alone dispositive. (See Service America, supra, 15 Cal.App.4th at
p. 1242.) Further, no attempt at valuing a unique or unusual property will likely be
precise or flawless. The fact that precisely similar comparable properties may not exist,
or that valuation information may not be available for comparable properties, is not the
fault of the parties or the experts. These may simply be unavoidable realities. Nor is it a
simple matter to “separate[e] the portion of the concession fee related to the use of
property from the portion of the fee based on other considerations.” (See id. at pp. 1237–
1240.) These challenges, too, ought to be considered in evaluating expert attempts at
valuation. Finally, some of the Board’s criticisms of DFS’s expert valuations were
rooted in the Board’s mistaken reliance on “rents” paid by duty-free operators at other
airports without considering that such “rents” presumably, as here, represent
consideration not only for real property but for intangible concession rights. With all of
this in mind, we encourage the Board to revisit the valuation evidence offered by DFS in
light of our holding that the MAG was consideration for DFS’s exclusive concession as
35
well as its possessory interest. Since it concluded (erroneously) otherwise, the Board was
not called on to determine the value of the intangible concession right or to separate it
from the value of the real property interest, a task which it must on remand undertake.

Outcome: The trial court erred in affirming the Board’s decision. Accordingly, we reverse
its judgment and remand to that court for further proceedings consistent with this opinion. Appellant is to recover costs on appeal.
