assets available for benefits for the year ended December 31, 2017, and the

financial statements present fairly, in all material respects, the net assets
available for benefits of the Plan as of December 31, 2017 and 2016, and the
changes in net assets available for benefits for the year ended December 31,
2017, in conformity with accounting principles generally accepted in the United

financial statements are the responsibility of the Plan&#8217;s management. Our
responsibility is to express an opinion on the Plan&#8217;s financial statements
based on our audits. We are a public accounting firm registered with the Public
Accounting Oversight Board (United States) (&#8220;PCAOB&#8221;) and are required to be
independent with respect to the Plan in accordance with the U.S. federal
securities laws and the applicable rules and regulations of the Securities and

<font color=black face="trebuchet ms,sans-serif" lang=EN-US style="font-size:10.5pt;">We
conducted our audits in accordance with the standards of the PCAOB. Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement, whether due to error or fraud. The Plan is not required to have,
nor were we engaged to perform, an audit of its internal control over financial
reporting. As part of our audits we are required to obtain an
understanding of internal control over financial reporting but
not for the purpose of expressing an opinion on the effectiveness of the Plan&#8217;s
internal control over financial reporting. Accordingly, we express no such
opinion.</font></p>

<font color=black face="trebuchet ms,sans-serif" lang=EN-US style="font-size:10.5pt;">Our
audits included performing procedures to assess the risk of material
misstatement of the financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. </font>
<font face="trebuchet ms,sans-serif" lang=EN-US style="font-size:10.5pt;">Such procedures
included </font>
<font color=black face="trebuchet ms,sans-serif" lang=EN-US style="font-size:10.5pt;">examining, on a test basis, evidence
regarding the amounts and disclosures in the financial statements. Our audits
also included evaluating the accounting principles used and significant
estimates made by the Plan&#8217;s management, as well as evaluating the overall
presentation of the financial statements. We believe that our audits provide a
reasonable basis for our opinion.</font></p>

supplemental information in the accompanying schedules of assets (held at end

the year ended December 31, 2017 have been subjected to audit procedures
performed in conjunction with the audit of the Plan&#8217;s financial statements. The
supplemental information is presented for the purpose of additional analysis
and is not a required part of the financial statements but includes
supplemental information required by the Department of Labor&#8217;s Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. The supplemental information is the responsibility of the
Plan&#8217;s management. Our audit procedures included determining whether the
supplemental information reconciles to the financial statements or the
underlying accounting and other records, as applicable, and performing
procedures to test the completeness and accuracy of the information presented
in the supplemental information. In forming our opinion on the supplemental
information, we evaluated whether the supplemental information, including its
form and content, is presented in conformity with the Department of Labor&#8217;s
Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. In our opinion, the supplemental

401(k) Savings Plan and Investment Partnership Plan (the &#8220;Plan&#8221; or the &#8220;RTAI
Plan&#8221;) provides only general information. Participants should refer to the plan
document and summary plan description for a more complete description of the
Plan&#8217;s provisions.</font></p>
<p style="margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<b><font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">General:</font></b><font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> The Plan is a defined contribution plan
covering all nonrepresented employees of Rio Tinto America Inc. and its
participating companies (collectively, the &#8220;Company&#8221; or the &#8220;Employer&#8221;), as defined
in the plan document. &#160;Rio Tinto America Inc. is an indirect wholly owned
subsidiary of Rio Tinto plc. &#160;All eligible full-time employees of the Company
can participate in the Plan immediately upon employment. Part-time employees
are eligible after completing 1,000 hours of service during a 12-month period.</font></p>
<p style="margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:0in;">
<font color=windowtext face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The Rio
Tinto America Inc. Benefits Governance Committee and the Investment Committee
decided to transition the custodial and recordkeeping functions from State
Street Bank &amp; Trust Company (&#8220;State Street&#8221; or &#8220;Plan Trustee&#8221;) and Xerox HR
Solutions, respectively, to Prudential Retirement Insurance and Annuity
Company. This transition occurred on February 1, 2017. In order to facilitate
this transition, a blackout period was established and enforced. For the period
from 4:00 PM on January 31, 2017 through February 13, 2017 (the blackout period),
participants were unable to direct or diversify investments in their individual
accounts, or receive a distribution from the Plan. During the transition, the
Rio Tinto America Inc. Savings Plan Trust (the &#8220;Master Trust&#8221;) was dissolved
and the</font><font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> Plan reverted to stand alone trust and plan accounting.</font></p>
<p style="margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The Plan is subject to the provisions of the Employee
Retirement Income Security Act of 1974 (&#8220;ERISA&#8221;), as amended.</font></p>

<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Contributions:</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> Participants may
elect, under a salary reduction agreement, to contribute to the Plan an amount
not less than one percent and not more than 50 percent of their eligible
compensation on a before-tax basis through payroll deductions. Before-tax
contributions are limited by the Internal Revenue Code (&#8220;IRC&#8221;), which
established a maximum contribution of $18,000 ($24,000 for participants age 50
or over) for the year ended December&nbsp;31, 2017. Participants may also elect
to make after-tax contributions not less than one&nbsp;percent and not more
than 50 percent of their eligible compensation. Total before-tax and after-tax
contributions cannot exceed 50 percent of each participant&#8217;s eligible
compensation. </font></p>
<p style="margin:0in;margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<font face=arial,sans-serif lang=EN-US style="font-size:10.0pt;">The
Company matches participants&#8217; before-tax and/or after-tax contributions to the
Plan at 100 percent, up to the first six percent of their eligible compensation.</font></p>
<p style="margin:0in;margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The Company makes Investment Partnership
Plan (&#8220;IPP&#8221;) contributions. To be eligible for IPP contributions, active employees
as of March 31, 2007, were given the choice to discontinue credited future
benefit service under the Company-sponsored defined benefit pension plan, the
Rio Tinto America Inc. Retirement Plan. Effective April 1, 2007, new
participants in the Plan were eligible to receive IPP contributions. The
Company contributes six percent of eligible compensation up to the Social
Security wage base ($127,200 for 2017) and 11.7 percent of eligible
compensation over the Social Security wage base.</font></p>
<p style="margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Participants are not required to contribute to the Plan to
receive IPP contributions. An employee who becomes disabled under the Company&#8217;s
long-term disability plan and who has attained five years of service, as
defined, will continue to receive IPP contributions from the Company until
their termination of employment from the Company, based on such participant&#8217;s
compensation at the date of disability. </font></p>

</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">An employee can make rollover contributions
from another qualified plan or an individual retirement account (&#8220;IRA&#8221;) if
certain criteria are met as set forth in the plan document.</font></p>

<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The Plan does not permit
participants to invest rollover
contributions into the common stock of the parent in the form of a unitized
fund with American Depository Receipts (&#8220;ADRs&#8221;) (the &#8220;Company Stock Fund&#8221; or &#8220;Employer

</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Each participant&#8217;s account is
credited with the participant&#8217;s contributions, the Company&#8217;s matching
contributions, IPP contributions (if applicable), an allocation of the Plan earnings
(losses), and administrative expenses. Allocations are based on participant
earnings (losses) or account balances, as defined. The benefit to which a
participant is entitled is the benefit that can be provided from the
participant&#8217;s vested account. Terminated participants are charged a quarterly fee
to offset recordkeeping expenses. </font></p>
<p style="margin:0in;margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Participant-directed options for investments:</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">
Participants have the option to allocate plan contributions among various investment
options, including the Rio Tinto ADR Stock Fund. All choices vary in types of
investments, rates of return and investment risk. Participants may elect to
have all or part of their account balances and future contributions invested in
one fund, transferred to another fund, or in any combination (except as noted
below). Participants also have the option to invest in managed funds that are
weighted by asset class, based on the participant&#8217;s retirement date. The funds
assume participants will retire upon reaching age 65 and invest in various
collective trust and mutual funds.</font></p>
<p style="margin:0in;margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The Plan limits the total amount of participant contributions
and the Company matching contributions to the Rio Tinto ADR Stock Fund to a maximum
of 20 percent of such contributions. The Plan does not permit participants to
transfer funds into the Rio Tinto ADR Stock Fund, including rollover
contributions; however, participants are permitted to transfer funds out of the
Rio Tinto ADR Stock Fund or to re-allocate their portfolio among all other
funds with the exception of the Rio Tinto ADR Stock Fund. See Note 9.</font></p>

<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Vesting:</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> Participants are immediately vested in their
contributions and Company matching contributions plus actual earnings or losses
thereon. Vesting in the Company&#8217;s IPP contributions is graded based on completed
years of service. A participant is 100 percent vested after three completed years
of credited service in IPP contributions, or at time of death or attainment of
age 65.</font></p>
<p style="margin:0in;margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Payment of benefits:</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> Upon termination, retirement,
death or becoming permanently disabled, participants, or their beneficiaries
may elect to receive lump-sum distributions, installment payments or rollover
distributions in an amount equal to the value of the participants&#8217; vested
interests in their accounts. If a participant terminates employment and the
participant&#8217;s account balance is less than $1,000, the Plan Administrator will
authorize the benefit payment in a single lump-sum without the participant&#8217;s
consent. During employment, participants may withdraw account balances for
financial hardship and other in-service withdrawals, as defined.</font></p>
<p style="margin:0in;margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Notes from participants:
</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Participants
may borrow from their total account balance a minimum of $1,000 up to a maximum
equal to the lesser of $50,000 or 50 percent of the participant&#8217;s total vested
account balance. Note terms range from one to five years or up to 20 years for
the purchase of a primary residence. Notes to participants are treated as a
separate investment of the participant, and all principal and interest payments
on note balances are credited to the participant account from which the note to
the participant was made. Notes from participants bear interest at rates
ranging from 4.25 percent to 7.75&nbsp;percent at December 31, 2017.</font></p>
<p style="margin:0in;margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Interest rates are two percent above the prime rate at the
beginning of the last month preceding the calendar quarter in which the loan is
approved, and are fixed for the term of the loan. </font></p>

<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Forfeitures:</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> Forfeitures are used to first restore
re-employed participants&#8217; IPP accounts and secondly to reduce future Company
contributions or to pay administrative expenses of the Plan. At December 31,
2017 and 2016, forfeited non-vested accounts were approximately $1,195,000 and $293,000.
&#160;Approximately $124,000 in forfeitures were used to pay administrative expenses
for the year ended December 31, 2017. No forfeitures were used to pay Company
contributions for the year ended December 31, 2017.</font></p>

<font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">If the distribution of a participant&#8217;s account is outstanding
for five years or more, and reasonable efforts were made to locate the
participant, such participant&#8217;s benefit may be forfeited. Any forfeitures from
the Plan can be utilized to reinstate benefits should a participant or
beneficiary make a claim for the forfeited benefit.</font></p>

<b><font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Basis of presentation:</font></b><font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> The financial statements of the
Plan reflect transactions on the accrual basis of accounting. </font></p>
<p style="margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<b><font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Use of estimates:</font></b><font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> The preparation of the financial
statements in conformity with accounting principles generally accepted in the
United States of America requires plan management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, and
disclosures of contingent assets and liabilities and changes therein, at the
date of the financial statements, and additions and deductions during the
reporting period. Actual results could differ from those estimates.</font></p>
<p style="margin:0in;margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Concentrations, risks and uncertainties:</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> The Plan
invests in various investment securities. Investment securities are exposed to
various risks, such as interest rate, market, currency exchange rate, and
credit risks. Due to the level of risk associated with certain investment securities,
it is reasonably possible that changes in the values of investment securities
will occur in the near term and that such changes could materially affect
participants&#8217; account balances and the amounts reported in the statements of
net assets available for benefits. The Plan&#8217;s investment in the Invesco Stable
Value Fund and the SSgA S&amp;P 500 Index Fund represented 15.2 percent and 11.0
percent of the Plan&#8217;s total investment balance, respectively, at December 31,
2017. The Plan&#8217;s investment in the Invesco Stable Value Fund and the SSgA
S&amp;P 500 Index Fund represented 18.6 percent and 10.1 percent of the Plan&#8217;s
total interest in the Master Trust at December 31, 2016. The Rio Tinto America
Inc. Savings Plan Investment Committee (&#8220;Investment Committee&#8221;) monitors
investment performance on a quarterly basis. </font></p>

<b><font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Investment valuation and income recognition:</font></b><font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">
Investments are reported at fair value. Fair value is the price that would be
received to sell an asset or paid to transfer a liability in an orderly
transaction between market participants at the measurement date. The Plan&#8217;s
Investment Committee determines the Plan&#8217;s valuation policies utilizing
information provided by the investment advisors and/or Plan Trustee. See Note 4
for a discussion of fair value measurements. </font></p>

<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Administrative expenses:</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> Certain investment advisor,
legal and other administrative fees were paid from the Plan for the year ended
December 31, 2017.&nbsp;The Company provides accounting and other services for
the Plan at no cost to the Plan.&nbsp;All other expenses related to
administering the Plan were paid by the Company, and were excluded from these
financial statements.</font></p>
<p style="margin:0in;margin-bottom:12.0pt;">
<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The Plan (and formerly the
Master Trust), has several fund managers that manage the investments held by
the Plan. Fees for certain investment fund management services are included as
a reduction of the return earned on each fund. These fees, net of expected
revenue sharing, range from 0.04 percent to 1.05 percent of investment fund
balances. The fees related to transaction costs associated with the purchase or
sale of Rio Tinto plc common stock ADRs are paid by the participants.</font></p>

<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Notes from participants:</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> Notes from participants are
measured at their unpaid principal balance plus any accrued but unpaid
interest. No allowance for credit losses has been recorded at December 31, 2017
or 2016. Defaulted notes from participants are recorded as a distribution in
the year of default. Interest income from loans is recorded on the accrual
basis.</font></p>

<font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Accounting guidance requires that participant loans be

<font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Prior to February 1, 2017, the Plan&#8217;s investments were included
in the investments of the Master Trust. Each participating retirement plan had a
divided interest in the Master Trust (based on the investment direction by plan
participants in the various investment options offered through the Master
Trust). The value of the Plan&#8217;s interest in the Master Trust was based on the
beginning of year value of the Plan&#8217;s interest in the Master Trust plus actual
contributions and allocated investment income (loss) less actual distributions
and allocated administrative expenses. Investment income (loss), investment
management fees and other direct expenses relating to the Master Trust were allocated
to the individual plans based on the average daily balances. Accrued income,
pending trades, and accrued expenses were de minimus at January 31, 2017 and December
31, 2016, and are included in the investment balances below. The Plan&#8217;s
interest in the Master Trust was 67.4 percent and 67.3 percent at January 31,

<p style="margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Accounting guidance provides the framework for measuring fair
value. The framework provides a fair value hierarchy that prioritizes the
inputs to valuation techniques used to measure fair value. The hierarchy gives
the highest priority to unadjusted quoted prices in active markets for
identical assets or liabilities (Level 1 measurements) and the lowest priority
to unobservable inputs (Level 3 measurements). The three levels of the fair
value hierarchy are described as follows:</font></p>
<p style="margin:0in;margin-bottom:.0001pt;margin-left:38.9pt;text-indent:-38.9pt;">
<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Level 1:&nbsp; Inputs
to the valuation methodology are unadjusted quoted prices for identical assets
or liabilities in active markets that the Plan has the ability to access.</font></p>
<p style="margin:0in;margin-bottom:.0001pt;margin-left:38.9pt;text-indent:-38.9pt;">
<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in;margin-bottom:.0001pt;margin-left:38.9pt;text-indent:-38.9pt;">
<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Level 2:&nbsp; Inputs
to the valuation methodology include quoted market prices for similar assets or
liabilities in active markets; quoted prices for identical or similar assets or
liabilities in inactive markets; inputs other than quoted prices that are
observable for the asset or liability; and inputs that are derived principally
from or corroborated by observable market data by correlation or other means.
If the asset or liability has a specified (contractual) term, the Level 2 input
must be observable for substantially the full term of the asset or liability.</font></p>
<p style="margin:0in;margin-bottom:.0001pt;margin-left:38.9pt;text-indent:-38.9pt;">
<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">&#160;</font></p>
<p style="margin:0in;margin-bottom:12.0pt;margin-left:38.9pt;margin-right:0in;margin-top:0in;text-indent:-38.9pt;">
<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Level 3:&nbsp; Inputs to the valuation
methodology are unobservable and significant to the fair value measurement.</font></p>
<p style="margin:0in;margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The asset&#8217;s or liability&#8217;s fair value measurement level within
the fair value hierarchy is based on the lowest level of any input that is
significant to the fair value measurement. Valuation techniques used need to
maximize the use of observable inputs and minimize the use of unobservable
inputs.</font></p>
<p style="margin-bottom:12.0pt;margin-left:0in;margin-right:0in;margin-top:6.0pt;">
<font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Following is a description of the valuation methodologies
used for assets measured at fair value. There have been no significant changes
in the methodologies used at December 31, 2017 and 2016.</font></p>

<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Mutual funds:</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> Mutual funds are valued at the daily
closing price as reported by the fund. Mutual funds are open-end mutual funds
that are registered with the U.S. Securities and Exchange Commission. These
funds are required to publish their daily net asset value (&#8220;NAV&#8221;) and to
transact at that price. The mutual funds are deemed to be actively traded.</font></p>

<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Stable value fund: collective investment trust:</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> The
stable value fund is valued at NAV per unit as a practical expedient, which is
calculated based on the fair values of the underlying funds. This practical
expedient would not be used if it is determined to be probable that the fund
will sell the investment for an amount different from the reported NAV. The
underlying funds include synthetic guaranteed investment contracts (&#8220;GICs&#8221;) and
traditional GICs, for which contract value is used as the fair value, since
contract value is the amount participants would receive if they were to
initiate permitted transactions under the terms of the Plan. Participant
transactions (purchases and sales) may occur daily. If the Plan initiates a
full redemption of the fund, the issuer reserves the right to require 12
months&#8217; notification in order to ensure that security liquidations will be
carried out in an orderly manner. </font></p>

<b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">Collective trust funds:</font></b><font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;"> The
collective trust funds are valued at the NAV per unit as a practical expedient,
which is based on the fair values of the underlying funds using a market
approach. This practical expedient would not be used if it is determined to be
probable that the fund will sell the investment for an amount different from
the reported NAV. Underlying equity investments for which market quotations are
readily available are reported at the last reported sale price on their
principal exchange, market or system on valuation date, or official close price
of certain markets. If no sales are reported for that day, investments are
valued at the last published sales price, the mean between the last reported
bid and asked prices, or at fair value as determined in good faith by the
trustee of the fund. Underlying short-term investments are stated at amortized
costs, which approximates fair value. Underlying registered investment
companies or collective investment funds are valued at their respective NAV.
Underlying fixed income investments are valued based on the basis of valuations
furnished by independent pricing services. In the event current market prices
or quotations are not readily available or deemed unreliable by the fund
trustee, the fair value of the underlying fund will be determined in good faith
by the fund trustee using alternative fair valuation methods. Participant
transactions (purchases and sales) may occur daily, at NAV per unit. There are
no restrictions on redemption.</font></p>

measured at fair value using the net asset value per share (or its equivalent)
practical expedient have not been classified in the fair value hierarchy. The
fair value amounts presented in this table are intended to permit
reconciliation of the fair value hierarchy to the amounts presented in the

fair value calculation that may not be indicative of net realizable value or
reflective of future fair values. Furthermore, while the Plan believes its
valuation methods are appropriate and consistent with other market
participants, the use of different methodologies or assumptions to determine the
fair value of certain financial instruments could result in a different fair
value measurement at the reporting date.</font></p>

<font face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The availability of observable market data is monitored to
assess the appropriate classification of financial instruments within the fair
value hierarchy. Changes in economic conditions or model-based valuation
techniques may require the transfer of financial instruments from one fair
value level to another. In such instances, the transfer is reported at the
beginning of the reporting period. The Plan (and previously the Master Trust),
evaluates the significance of transfers between levels based upon the nature of
the financial instrument and size of the transfer relative to total net assets
available for benefits. For the year ended December 31, 2017, there were no
transfers between levels.</font></p>

<font color=black face=Arial,sans-serif lang=EN-US style="font-size:10.0pt;">The Plan (and previously the Master Trust), follows guidance
on how entities should estimate fair value of certain alternative investments.
The fair value of investments within the scope of the guidance can be
determined using NAV per share as a practical expedient, when fair value is not
readily determinable, unless it is probable the investment will be sold at
something other than NAV. </font></p>

changes to the language pertaining to Plan limits and annual additions, and to
close the Company Stock Fund to new contributions of any kind, including transfers,
as of June 29, 2018.&#160; The Plan was further amended, effective June 1, 2018, to
