RE: Single Security Initiative and Diversification under Section 817(h)
Dear Mr. Vallabhaneni and Mr. Paul:
The Investment Company Institute (ICI) and the Securities Industry and Financial
Markets Association (SIFMA)1 request clarification of the guidance recently provided in Rev.
Proc. 2018-54. The guidance addresses the diversification requirements of section 817(h) as
applied to Uniform Mortgage-Backed Securities (UMBS) that Fannie Mae and Freddie Mac plan
to issue as part of their Single Security Initiative. The guidance allows taxpayers to elect to treat
UMBS purchased in the To-Be-Announced (TBA) market as having certain deemed issuers for
purposes of section 817(h).
Our members manage and advise investment funds and managed accounts that serve as
investment vehicles for life insurance company segregated asset accounts supporting variable
insurance and variable annuity contracts. As such, they are responsible for compliance with the
asset diversification requirements of section 817(h) and thus greatly appreciate the guidance
provided by the Internal Revenue Service (IRS) and Treasury Department in Rev. Proc. 2018-54.
We remain concerned, however, that the guidance does not address the more pressing
diversification issue for these transactions regarding which entity is treated as the “issuer” of a
TBA contract for purposes of section 817(h) if that contract is held over a quarter-end. We also
are concerned about the operational feasibility of applying the deemed issuance ratio in Rev.
Proc. 2018-54 to UMBS that are physically delivered pursuant to a TBA transaction. We thus
ask the IRS and Treasury Department to provide that:
(1) Taxpayers may elect to apply the deemed issuance ratio from Rev. Proc. 2018-54 to
UMBS TBA contracts before the underlying UMBS have been physically delivered; and
1 Descriptions of ICI and SIFMA and their respective memberships are attached.

(2) The deemed issuance ratio election applies separately to a TBA contract and the UMBS
that are delivered pursuant to that contract, so that the deemed issuer election could apply
to an open TBA contract prior to the UMBS being delivered without the election also
applying to the UMBS once they are physically delivered.
Background
Single Security Initiative
Pursuant to the Single Security Initiative and under the direction of the Federal Housing
Finance Agency (FHFA), the Federal Home Loan Mortgage Corporation (Freddie Mac) will
align key features of its securities with those of the Federal National Mortgage Association
(Fannie Mae, and together with Freddie Mac, the GSEs) to create the new UMBS. The UMBS
then will be issued by both GSEs with substantially similar terms and will trade primarily in the
TBA market. The FHFA and the GSEs hope these changes will increase liquidity and reduce
costs in the mortgage-backed security (MBS) market.
The FHFA and GSEs plan to implement the Single Security Initiative in June 2019,
which means that UMBS TBAs likely will begin trading by March. Once trading begins,
investors that acquire UMBS in unstipulated TBA transactions will not know whether Fannie
Mae, Freddie Mac, or some combination thereof will be the issuer(s) of the securities to be
delivered until 48 hours prior to settlement.
Investment in the TBA Market for MBS
The TBA market is by far the most liquid and important secondary market for MBS and
one of the most liquid fixed income markets globally. The TBA market is responsible for
significant capital flow from a wide range of investors, including life insurance company
separate accounts and related investment funds. We estimate the portion of the market subject to
section 817(h) and potentially impacted by the treatment of TBAs to be approximately $200
billion or higher.
TBA trades can be stipulated or unstipulated. Today, in an unstipulated TBA trade, the
price, issuer, coupon, settlement month, size of trade, and maturity are known at the time of
trade.2 With the advent of UMBS, the issuer will no longer be specified or known; the trade will
simply be for UMBS.
In a stipulated TBA trade, certain additional parameters are specified when the parties
enter into the TBA contract. For example, a buyer may stipulate that only new pools be
delivered, or the buyer may wish to avoid MBS pools from certain seller-servicers. These
stipulated TBA trades place additional burdens and risks on trade counterparties, and accordingly
market makers often will demand additional compensation (through trade pricing) for such
trades. These costs are borne by end-investors in mutual and other funds. Stipulated trading also
2 For example, A buyer may place an order for $5 million of FNMA 5% 30-year MBS to settle in April at a price of
104. The specific CUSIPs will not be know until two days before the settlement date.

reduces TBA market volume and liquidity. Accordingly, with regard to UMBS, the industry has
consistently expressed a desire to minimize any additional stipulated trading driven by the
construction of UMBS or the regulatory regime around it so as to maximize TBA market
liquidity and help ensure a smooth transition to the new market.
Diversification under Section 817(h)
Section 817(h) prescribes a diversification requirement for segregated asset accounts
supporting variable insurance contracts. In general, section 817(h)(1) provides that a variable
contract that is based on a segregated asset account shall not be treated as an annuity, endowment
or life insurance contract for any period for which the investments made by the account are not
adequately diversified. A failure to satisfy section 817(h) will result in significantly adverse tax
consequences for any policyholders who own the affected variable contracts.3 Because of this,
our members typically maintain a high degree of conservatism regarding compliance with these
requirements.
The regulations set forth detailed rules for the diversification requirement. In general
terms, the values of a segregated asset account’s investments must satisfy certain concentration
limits as of the last day of each calendar quarter or within the ensuing 30 days.4 For these
purposes, all securities of the same “issuer” are treated as a single investment, thus requiring the
segregated asset account to identify the “issuer” of the securities the account holds.5 Various
special rules apply for purposes of the diversification test. For example, each US government
agency or instrumentality (such as Fannie Mae or Freddie Mac) is treated as a separate issuer,6
and look-through treatment applies to certain types of insurance-dedicated investment entities in
which the segregated asset account invests (hereinafter, IDFs).7
Revenue Procedure 2018-54
As indicated above, investors that acquire UMBS in unstipulated TBA transactions will
not know whether Fannie Mae, Freddie Mac, or some combination thereof will be the issuer(s)
3 Specifically, the “income on the contract” generally is treated as ordinary income received or accrued by the
policyholder for the year, resulting in a loss of tax deferral for gains credited to the policy. Treas. Reg. § 1.817-
5(a)(1). In some cases, a life insurance company may be able to correct inadvertent non-compliance, but doing so
can be very costly. See Treas. Reg. § 1.817-5(a)(2); Rev. Proc. 2008-41, 2008-29 I.R.B. 155. In addition, non-
compliance can adversely affect the federal income tax returns of the issuing life insurance companies.
4 See generally Treas. Reg. § 1.817-5(b) and (c).
5 Treas. Reg. § 1.817-5(b)(1)(ii)(A).
6 Sec. 817(h)(6); Treas. Reg. § 1.817-5(b)(1)(ii).
7 Sec. 817(h)(4); Treas. Reg. § 1.817-5(f). The types of look-through entities are limited to regulated investment
companies (RICs), real estate investment trusts, partnerships, and grantor trusts. Such an entity is insurance-
dedicated if beneficial interests in the entity and public access to the entity are limited to life insurance company
segregated asset accounts or certain other limited classes of investors listed in the regulations.

of the securities to be delivered until 48 hours prior to settlement. This has caused concern
regarding how segregated asset accounts and IDFs will manage compliance with section 817(h).
Rev. Proc. 2018-54 provides an option that investment managers may use to address this
uncertainty. It allows a “taxpayer”8 to make an election pursuant to which “generic GSE
securities”9 acquired through settlement of a TBA trade will be deemed to be issued in part by
Freddie Mac and in part by Fannie Mae, regardless of the actual issuer of the delivered securities.
The portions deemed issued by each GSE are determined by the “deemed issuance ratio” for the
year the TBA contract was entered into, which the FHFA will announce annually. The deemed
issuance ratio applies for as long as the electing taxpayer holds the generic GSE security. The
ratio also remains constant with respect to the delivered securities, even as they pay down and
even if the taxpayer disposes of some of the securities.
Industry Concerns
Lack of Guidance on Open TBA Contracts for UMBS
Rev. Proc. 2018-54 applies to UMBS that are acquired through the TBA market, but it
does not directly address the treatment of the TBA contracts themselves. TBA contracts are
forward contracts that generally are settled mid-month, so it is not uncommon for a segregated
asset account’s portfolio to include unsettled TBA contracts when the diversification test applies
on the last day of a calendar quarter. Furthermore, segregated asset accounts often “roll” open
TBA contracts rather than settling them,10 which increases the likelihood that the portfolio will
include unsettled TBA contracts on the testing date. Certain segregated accounts may hold TBAs
as a hedge or analytic exposure and will never take delivery of pools, and thus always will have
unsettled TBA contracts when the diversification tests take place.
The issue raised by the open TBA contracts is that the segregated asset account will not
know whether Fannie Mae, Freddie Mac, or some combination thereof will be the issuer of the
securities that will be delivered until 48 hours prior to settlement. If the taxpayer holds the TBA
contracts over a quarter-end, it is unclear how the contracts should be treated for diversification
8 For this purpose, a “taxpayer” is defined as “(1) An insurance company that issues variable contracts within the
meaning of § 817(d); and (2) An investment company, partnership, or trust … that qualifies for ‘look-through’
treatment under § 1.817-5(f).”
9 A “generic GSE security” is a TBA-eligible security that a buyer acquires by taking delivery pursuant to a TBA
trade in which, at the time the buyer enters into the contract, the buyer cannot know the actual issuer of the securities
to be delivered under the contract.
10 Rather than physically settling the contracts, the parties may choose to close the initial contract and open a new
longer-term contract for the same underlying assets at the current fair market value.

testing purposes. Accordingly, we ask the IRS and Treasury Department to clarify that taxpayers
may apply the guidance in Rev. Proc. 2018-54 to open TBA contracts.11
Absent such clarification, taxpayers could avoid the UMBS TBA market altogether and
enter into contracts only in the stipulated TBA market (in which the taxpayer can stipulate
whether it wants to receive Freddie Mac or Fannie Mae securities). Entering into stipulated
TBAs, however, is not desirable for the reasons discussed above: Increased risk to
counterparties, increased costs to investors, and decreased liquidity in the TBA market. More
importantly, it could undermine the purpose of the Single Security Initiative, which is to increase
the fungibility of the GSE securities and their liquidity in the market, by providing an incentive
for market participants to recreate, with stipulations, the bifurcated market we have today that the
single security initiative seeks to change.12
Separate Elections for TBA Contracts and the Delivered UMBS
It is not uncommon for taxpayers to acquire GSE securities through sources other than
the TBA market. Consequently, a taxpayer may simultaneously hold both a GSE security that it
acquired by delivery through the TBA market, and an identical GSE security of the same issuer
acquired in an open-market purchase. Regardless of how a GSE security is acquired, it is always
assigned the same CUSIP number, which is a standardized system for identifying securities.13
For example, the MBS issued by Fannie Mae have the same CUSIP number whether they are
acquired in a TBA trade or otherwise. This will continue to be the case after the Single Security
Initiative goes live – Fannie Mae securities and Freddie Mac securities still will have different
CUSIP numbers. The procedures and computer systems that taxpayers use to administer the
section 817(h) diversification test almost always rely upon the CUSIP numbers assigned to the
securities in the portfolio. In contrast, TBA contracts have generic CUSIP numbers that indicate
the issuer, settlement month, and product type.14
If a taxpayer makes the election permitted by Rev. Proc. 2018-54 as currently written, the
taxpayer must treat the GSE securities delivered in a TBA trade as issued by Fannie Mae or
Freddie Mac in accordance with the deemed issuance ratio regardless of the actual issuer of the
delivered securities. This, in turn, means that in many cases the taxpayer will need to disregard
the CUSIP number assigned to a particular GSE security, treat two GSE securities with the same
11 We ask that the IRS and Treasury state that no negative inference is to be made regarding section 817(h)
compliance testing done before such guidance.
12 Alternatively, in the absence of guidance, taxpayers may conclude that they must test the portfolio twice by
treating the TBAs as being issued first by one GSE and then by the other GSE to ensure that neither results in a
diversification problem.
13 “CUSIP” stands for the Committee on Uniform Securities Identification Procedures.
14 The generic CUSIPs for the UMBS TBAs will all reference Fannie Mae, even if the underlying issuer ultimately
is Freddie Mac.
Letter re Sec. 817(h)

Page 6 of 9
CUSIP number as having different issuers (actual issuer versus deemed issuers),15 and/or treat
two GSE securities with different CUSIP numbers as having the same deemed issuer.16
Moreover, this treatment will continue to apply for the entire period the taxpayer holds the GSE
securities. All of this will require significant changes to taxpayers’ procedures and computer
systems, including new recordkeeping systems to track the deemed issuers over time for multiple
tranches of GSE securities. The costs of implementing such procedural and system changes may
well outweigh the utility of the relief that Rev. Proc. 2018-54 provides. Indeed, it is our
understanding that many taxpayers likely will not make a deemed issuance election for UMBS
for this reason.
On the other hand, making the election with respect to an open TBA contract – as we
have requested above – would not entail these types of additional costs and compliance burdens
because all UMBS TBA contracts with the same CUSIP would have the same problem of issuer
identification, and taxpayers would need to apply the deemed issuance ratio to all such TBA
contracts As a result, if the IRS and Treasury provide the additional guidance on open TBA
contracts as we have requested, we ask for further clarification that taxpayers may apply the
deemed issuance ratio election separately to TBA contracts and the UMBS delivered with
respect to those TBA contracts. In fact, if our request is granted, we expect that many of our
members would make the deemed issuance election for the TBA contracts but not for the UMBS
themselves.17
Other Issues
In addition to the primary concerns outlined above, our members have raised other issues
regarding Revenue Procedure 2018-54:
(1) Changes to the deemed issuance ratio introduce operational and other complexities
for fund managers and taxpayers. The most significant of these is that securities
acquired through a TBA trade in December could have a different deemed issuance
ratio from securities with the same CUSIP acquired in January of the next year. This
difference in ratio for two identical securities would complicate compliance and
analysis. Small changes in the deemed issuance ration would cause outsized burdens
15 For example, a taxpayer could have two securities with the same CUSIP: One acquired by delivery of a TBA
with a deemed issuance ratio of 60% Fannie Mae and 40% Freddie Mac; and the other acquired by purchase in the
open market with an actual issuer of Fannie Mae (100%).
16 For example, a taxpayer could have two securities with different CUSIPs, the same deemed issuer, and different
actual issuers: One security acquired by delivery of an April 2019 TBA with a deemed issuance ratio of 60% Fannie
Mae and 40% Freddie Mac and an actual issuer of Freddie Mac (100%); and the other acquired by delivery of an
October 2019 TBA with the same deemed issuer (60% Fannie Mae and 40% Freddie Mac) and a different actual
issuer of Fannie Mae (100%).
17 Any new guidance should clarify that it does not create any inferences for other situations, and provide relief for
taxpayers who, in the past, have applied section 817(h) by treating the counterparty as the issuer of an open TBA.

on market participants and taxpayers, with no consummate benefit, and should be
avoided.
(2) The definition of “taxpayer” presents some ambiguity because both the insurance
company and the IDF are treated as “taxpayers” that could potentially take conflicting
actions with respect to the permitted election. Clarification on which entity makes the
election is needed to prevent confusion and conflicting or duplicate elections with
respect to the same assets. Further, the guidance suggests that an insurance
company’s election applies to all its separate accounts/sub-accounts. Insurance
companies should be permitted more flexibility in managing these elections.18
(3) To revoke a deemed issuance election, a taxpayer must seek the consent of the
Commissioner of the IRS by filing a request for a private letter ruling. This seems
excessive and quite burdensome for taxpayers. A less onerous requirement, such as
revocation through a notice or statement filed with a tax return, would provide
adequate notification to the IRS without creating additional burdens or costs to the
taxpayer.
Request for Guidance
For the reasons discussed above, we respectfully request the IRS and Treasury
Department provide that:
(1) Taxpayers may elect to apply the deemed issuance ratio from Rev. Proc. 2018-54 to
UMBS TBA contracts before the underlying UMBS have been physically delivered; and
(2) The deemed issuance ratio election applies separately to a TBA contract and the UMBS
that are delivered pursuant to that contract, so that the deemed issuer election could apply
to an open TBA contract prior to the UMBS being delivered without that election also
applying to the UMBS once they are physically delivered.
To address our additional concerns, we also ask the IRS and Treasury to provide that:
(a) The deemed issuance ratio will be adjusted annually only if the change in the ratio is
material. We suggest a reasonable threshold would be 5 percent.
(b) The “taxpayer” that makes the deemed issuance ratio election with respect to any GSE
securities or TBA contracts is the entity that acquires those securities or contracts (either

the insurance company segregated asset account or the IDF). If the taxpayer is the
insurance company, the election is made separately for each segregated asset account.
(c) A taxpayer may revoke the deemed issuance ratio election by stating that it is doing so in
a statement or form filed with its tax return for the year in which the taxpayer wishes to
no longer apply the deemed issuance ratio.

ICI and SIFMA believe addressing the important issues outlined in this letter will help to
ensure that the significant proportion of market participants bound by section 817(h) are able to
participate actively and without restriction in the TBA market. This will serve not only those
taxpayers, but also the millions of mortgage borrowers served by the TBA market each year. We
appreciate your attention to our requests and look forward to meeting with you soon to discuss
our concerns. In the meantime, please do not hesitate to contact us if you have any questions.
