the years then ended, in conformity with accounting principles generally accepted in the United States of America. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Basis for Opinion </B></P>

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" ALIGN="justify">We conducted
our audits in accordance with 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.
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>Report on Supplemental Schedules </B></P>

for the year ended December&nbsp;31, 2017 have been subjected to audit procedures performed in conjunction with the audit of the Plan&#146;s financial statements. The supplemental schedules are the responsibility of the Plan&#146;s management. Our
audit procedures included determining whether the supplemental schedules reconcile 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 supplemental schedules, we evaluated whether the supplemental schedules, including their form and content, are presented in compliance 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, such schedules are fairly stated, in all material respects, in relation to the financial statements as a

STYLE="white-space:nowrap">12-month</FONT> period. A participant&#146;s loan is financed proportionately from the account balances held in each investment. Loans can be repaid in one, two, three, four or five years or, in the case of a home
purchase, up to 15&nbsp;years. The interest rate on the loans is 1% above the United States of America prime rate on the last business day of the calendar month preceding the calendar month in which the loan is granted. Loans are repaid through
payroll deductions and are secured by the participant&#146;s remaining account balance. If the participant terminates employment with the Company, either the outstanding loan balance must be repaid in a lump sum or distributions to the participant
will be reduced accordingly. All new loans for the years ending December&nbsp;31, 2017 and December&nbsp;31, 2016 had an interest rate of 5.25% and 4.50%, respectively. </P>

the trustee is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investments held by the fund (a diversified portfolio of U.S. and international stocks, inflation-hedging securities, U.S.
bonds and cash reserves) less its liabilities. This practical expedient is not used when it is determined to be probable that the fund will sell the investment for an amount different than the reported net asset value. Participant transactions
(purchased and sales) may occur daily. Were the Plan to initiate a full redemption of the collective trust, the investment advisor reserves the right to temporarily delay withdrawal from the trust in order to ensure that securities liquidations will
be carried out in an orderly business manner. These investments are available to redeem immediately, and there are no redemption restrictions or notice periods required. There were no unfunded commitments as of December&nbsp;31, 2017. </P>

accumulated values of the underlying investments. The underlying investments are public investment vehicles valued using NAV per share. The NAV is based upon the value of the underlying assets owned by the fund, minus its liabilities, and then
divided by the number of shares outstanding. The NAVs of the underlying investments are quoted in an active market. The Plan has no unfunded commitments related to the pooled separate accounts and redemptions and subscriptions are permitted daily.

that simulates the performance of a guaranteed investment contract, whereby participants execute Plan transactions at contract value. Contract value represents contributions made to the fund, plus earnings, less participant withdrawals. The
self-managed stable value fund is composed of a portfolio of bonds and other fixed income securities owned by the Plan and an investment contract issued by an insurance company designed to provide a contract value &#147;wrapper&#148; around the
fixed income portfolio to guarantee a specific interest rate which is reset quarterly and that cannot be less than zero. The wrapper contract provides that realized and unrealized gains and losses on the underlying fixed income portfolio are not
reflected immediately in the net assets of the fund, but rather are amortized over the duration of the underlying assets through adjustments to the future interest crediting rate. Primary variables impacting future crediting rates of the Fund
include the current yield, duration, and existing difference between market and contract value of the underlying assets within the wrap contract. </P>
