<P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">On September&nbsp;29, 2016, the Alcoa Inc. Board of Directors approved the separation of Alcoa Inc. into two independent publicly traded
companies. On November&nbsp;1, 2016, the separation transaction was completed and became effective. Alcoa Inc. was renamed Arconic Inc., and the company spun off was named Alcoa Corporation. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">In anticipation of the separation of Alcoa Inc., Alcoa USA Corp., a subsidiary of newly formed Alcoa Corporation both before and after the
separation established the Retirement Savings Plan for Hourly Employees of Alcoa USA Corp. and the Retirement Savings Plan for Salaried Employees of Alcoa USA Corp (collectively, the &#147;Alcoa USA Corp. Plans&#148;). The Alcoa USA Corp. Plans were
effective August&nbsp;1, 2016. The accounts attributable to all participants who were employees or former employees assigned to Alcoa Corporation were transferred to the Alcoa USA Corp. Plans, and such individuals ceased to be participants in the
Plans. On August&nbsp;1, 2016, net assets of $983,338,005 were transferred to the Alcoa USA Corp. Plans, of which $374,983,667 were transferred from the Bargaining Plan, $580,086,974 were transferred from the Salaried Plan and $28,267,364 were

the Alcoa Retirement Savings Plan for Hourly <FONT STYLE="white-space:nowrap">Non-Bargaining</FONT> Employees was renamed the Arconic Hourly <FONT STYLE="white-space:nowrap">Non-Bargaining</FONT> Retirement Savings Plan, and the Alcoa Retirement

<P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Prior to the separation of Alcoa Inc., one of the Plans&#146; investment options was the Alcoa Stock Fund, which primarily invested in Alcoa
Inc. common stock. Upon separation on November&nbsp;1, 2016, the Alcoa Inc. Stock Fund was renamed the Arconic Stock Fund, and the Alcoa Corporation Stock Fund (a <FONT STYLE="white-space:nowrap">non-employer</FONT> stock fund holding Alcoa
Corporation common stock), was established. On November&nbsp;1, 2016, each shareholder of record of Alcoa Inc. common stock as of the close of business on October&nbsp;20, 2016 received one share of Alcoa Corporation common stock for every three
shares of Alcoa Inc. common stock owned. The Alcoa Corporation Stock Fund was frozen to new investments, other than the reinvestment of Alcoa Corporation dividends, if any. The Alcoa Corporation Stock Fund was liquidated on October&nbsp;6, 2017. Any
funds remaining in the Alcoa Corporation Stock Fund at the liquidation date were credited to participant accounts in the applicable BlackRock LifePath Fund, which are the Plans&#146; Qualified Default Investment Alternative Funds. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The Plans are available to eligible employees of the Company and certain subsidiary locations that have adopted the Plans. The Bargaining and
ATEP Plans are only available to hourly employees of the Company covered by collective bargaining agreements that provide this benefit. Employees are immediately eligible for plan participation. Participants are fully vested in the value of their
contributions plus actual earnings thereon at all times. Except for the participants in the ATEP Plan, a participant is immediately vested in company contributions, which are therefore nonforfeitable. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">For the ATEP Plan, employer contributions and the earnings on those contributions vest incrementally: 33% after one year of service, 67% after
two years and 100% vested after three years of service. Amounts that are not vested upon termination of employment are forfeited and will be used to reduce plan expenses or future company contributions. Total forfeitures that reduced employer
contributions and plan expenses in 2017 are $17,492. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><B>Employee Contributions </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Eligible employees may elect to contribute to the Plans up to 25% of eligible compensation as <FONT STYLE="white-space:nowrap">pre-tax,</FONT>
not to exceed the IRS limit, or up to 10% as <FONT STYLE="white-space:nowrap">after-tax,</FONT> with a maximum of 25% in the aggregate. Effective March&nbsp;1, 2015, eligible employees in the Arconic Bargaining Retirement Savings Plan may defer as <FONT
STYLE="white-space:nowrap">pre-tax</FONT> savings and/or <FONT STYLE="white-space:nowrap">pre-tax</FONT> <FONT STYLE="white-space:nowrap">catch-up</FONT> contributions, a maximum of 50% of amounts earned under the applicable pay for performance plan
(2015 or later plans only) in increments of 10% and subject to the maximums allowable by the Code and Department of Treasury regulations. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Negotiated deferrals, as defined in the Bargaining Plan document, for certain eligible collective bargained employees will be contributed to
their plan accounts as a separate <FONT STYLE="white-space:nowrap">pre-tax</FONT> contribution. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Eligible employees age 50 or older or who
become age 50 during the plan year who meet certain requirements may elect to make additional <FONT STYLE="white-space:nowrap">pre-tax</FONT> <FONT STYLE="white-space:nowrap">catch-up</FONT> contributions up to a maximum of $6,000, or such other
amount adjusted for <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">cost-of-living</FONT></FONT> increases. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Elections
can be changed effective for the first full payroll period following the election. Participants direct their contributions in multiples of 1% into various investment options offered by the Plans. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Eligible employees hired or rehired on or after August&nbsp;1, 2006 will be automatically enrolled in the Plans after 60 days of hire or
rehire and subject to automatic payroll deductions equal to 3% of eligible compensation, which will be contributed to the Plans as <FONT STYLE="white-space:nowrap">pre-tax</FONT> savings, unless the employee chooses to either enroll sooner or to not
participate. After 90 days of plan participation, the <FONT STYLE="white-space:nowrap">pre-tax</FONT> savings rate will be increased by 1% on each April&nbsp;1 until the <FONT STYLE="white-space:nowrap">pre-tax</FONT> savings rate attains a target
rate of 6% of eligible compensation. The employee can change the contribution rate, annual rate increase and target contribution rate or stop automatic enrollment at any time. </P>

employer match for contributions to the Bargaining Plan and ATEP Plan is based upon the various collective bargaining agreements.&nbsp;The Company does not match negotiated deferral contributions under the Bargaining Plan. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The employer match for the Plans is contributed in the same manner as the participant&#146;s other investment elections. If the participant

<P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Certain eligible employees in the Bargaining Plan hired or rehired as of specified dates negotiated with the unions will receive retiree

the lesser of 50% of the participant&#146;s account balance or $50,000. Loans are collateralized by a portion of the participant&#146;s account balance, and repayments are made by periodic payroll deductions. Interest is charged on all loans at the

presented in a separate line items in the statement of net assets available for benefits and in the statement of changes in net assets available for benefits, respectively. Additionally, the guidance removes the requirement to disclose the
percentage interest in the master trust for plans with divided interests and requires that all plans disclose the dollar amount of their interest in each of those general types of investments. Lastly, the guidance requires all plans to disclose
their master trust&#146;s other asset and liability balances and the dollar amount of the plan&#146;s interest in each of those balances. This ASU&nbsp;is effective for fiscal years beginning after December&nbsp;15, 2018 and is to be applied

are synthetic. The Investment Contracts are held in the Fixed Income Fund (the &#147;Fund&#148;) and are credited with earnings on the underlying investments and charged for participant withdrawals and administrative expenses. The wrap providers are
contractually obligated to repay the principal by providing a guarantee that the crediting rate will not fall below 0%. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Contract value,
as reported to the Plans by the investment manager, represents contributions made under contract, plus earnings, less participant withdrawals and administrative expenses. Participants may ordinarily direct the withdrawal or transfer of all or a
portion of their investment at contract value. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">Investment Contracts use the crediting rate formula to convert market value changes in the
covered assets into income distributions in order to minimize the difference between the market and contract value of covered assets over time. Using the crediting rate formula, an estimated future market value is calculated by compounding the
Fund&#146;s current market value at the Fund&#146;s current yield to maturity for a period equal to the Fund&#146;s duration. The crediting rate is the discount rate that equates estimated future market value with the Fund&#146;s current contract
value, but it may not be less than zero. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman">The crediting rate, and hence the Fund&#146;s return, may be affected by many factors, including
purchases and redemptions by shareholders. If the market value of the covered assets is higher than their contract value, the crediting rate will ordinarily be higher than the yield of the covered assets. Under these circumstances, cash from new
investors will tend to lower the crediting rate, and redemptions by existing shareholders will tend to increase the crediting rate. The opposite is ordinarily true if the market value of the covered assets is lower than their contract value. There
are no reserves against contract value for credit risk of the insurance companies or otherwise. </P>
