<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">To the Plan Participants, Plan Administrator and Savings and Investment Committee of Superior Tube Company, Inc. Union 401(k) Plan </P>

accompanying statements of assets available for benefits of Superior Tube Company, Inc. Union 401(k) Plan (the Plan) as of December&nbsp;31, 2019 and 2018, and the related statements of changes in assets available for benefits for the years then
ended, and the related notes (collectively referred to as the &#147;financial statements&#148;). In our opinion, the financial statements present fairly, in all material respects, the assets available for benefits of the Plan at December&nbsp;31,
2019 and 2018, and the changes in its assets available for benefits for the years then ended, in conformity with U.S. generally accepted accounting principles. </P>

responsibility of the Plan&#146;s management. Our responsibility is to express an opinion on the Plan&#146;s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board
(United States) (PCAOB) 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 Exchange Commission and the PCAOB. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">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&#146;s internal control over financial reporting. Accordingly, we
express no such opinion. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due
to error or fraud, and performing procedures that respond to those risks. Such procedures included 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 management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Supplemental Schedules </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The accompanying supplemental
schedules of delinquent participant contributions for the year ended December&nbsp;31, 2019 and assets (held at end of year) as of December&nbsp;31, 2019, have been subjected to audit procedures performed in conjunction with the audit of the
Plan&#146;s financial statements. The information in the supplemental schedules is the responsibility of the Plan&#146;s management. Our audit procedures included determining whether the 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 schedules. In forming our opinion on the information, we evaluated whether such
information, including its form and content, is presented in conformity with the Department of Labor&#146;s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the information
is fairly stated, in all material respects, in relation to the financial statements as a whole. </P> <P STYLE="font-size:12pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P><DIV ALIGN="right">

inception or for a reasonable period of time in excess of 60 months for the purchase of a principal residence, as fixed by the Plan. The loans are secured by the balance in the participant&#146;s account and bear interest at rates established by the

expectancy of the Participant and his/her designated beneficiary. If a participant&#146;s vested benefit derived from employer and employee contributions is less than $5,000 but more than $1,000, and the participant does not make an affirmative
election otherwise, the administrator will roll over the balance into an individual retirement account. If a participant&#146;s vested balance is $1,000 or less, and the participant does not make an affirmative election otherwise, they will receive

receivable from participants represent participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on notes receivable from participants is recorded when it is earned. Related fees are
paid from participants&#146; accounts. No allowance for credit losses has been recorded at December&nbsp;31, 2019 and 2018. If a participant ceases to make loan repayments and the plan administrator deems the participant loan to be a distribution,
the participant loan balance is reduced and a benefit payment is recorded. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Risks and Uncertainties </B></P>

and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially

future contract interest crediting rate. The wrap contract provides that the adjustments to the interest crediting rate will not result in a future interest crediting rate that is less than zero.
In general, if the contract value exceeds the fair value of the underlying investments (including accrued interest), VRIAC becomes obligated to pay that difference to the Voya Separate Account in the event that redemptions result in a total contract
liquidation. In the event that there are partial redemptions that would otherwise cause the contract&#146;s crediting rate to fall below zero, VRIAC is obligated to contribute to the Voya Separate Account an amount necessary to maintain the
contract&#146;s crediting rate of at least zero percent. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The interest crediting rate is typically reset on a quarterly basis. Over time,
the crediting rate formula amortizes the Voya Separate Account&#146;s realized and unrealized fair value gains and losses over the duration of the underlying investments. Because changes in market interest rates affect the yield to maturity and the
fair value of the underlying investments, they can have a material impact on the contract&#146;s interest crediting rate. In addition, Participant withdrawals and transfers from the Voya Separate Account are paid at contract value but funded through
the liquidation of the underlying investments at fair value, which also impacts the interest crediting rate. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In certain circumstances,
the amount withdrawn from the contract would be payable at fair value rather than at contract value. These events include termination of the Plan, a material adverse change to the provisions of the Plan, the employer elects to withdraw from a
contract in order to switch to a different investment provider, or the terms of a successor plan (in the event of the <FONT STYLE="white-space:nowrap">spin-off</FONT> or sale of a division) do not meet VRIAC&#146;s underwriting criteria for issuance
of a clone wrap contract. The Company believes that the events described above that could result in the payment of benefits at fair value rather than contract value are not probable of occurring in the foreseeable future. </P>

status, <FONT STYLE="white-space:nowrap">un-cured</FONT> material breaches of responsibilities, or material and adverse changes to the provisions of the Plan. If one of these events was to occur, VRIAC could terminate the wrap contract at the fair
