our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free
of material misstatement. We were not engaged to perform an audit of the Plan&#146;s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures
that are appropriate in the circumstances, 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. An audit also includes examining,
on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for our opinion. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In our opinion, the financial statements referred to above present fairly, in all
material respects, the net assets available for benefits of the National Oilwell Varco, Inc. 401(k) and Retirement Savings Plan at December&nbsp;31, 2015 and 2014, and the changes in its net assets available for benefits for the year ended

of year) as of December&nbsp;31, 2015, has been subjected to audit procedures performed in conjunction with the audit of National Oilwell Varco, Inc. 401(k) and Retirement Savings Plan&#146;s financial statements. The information in the supplemental
schedule 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 schedule. 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 taken as a whole. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; margin-left:54%; text-indent:-2%; font-size:10pt; font-family:Times New Roman">/s/ Ernst&nbsp;&amp; Young LLP </P>

information only. Participants should refer to the <I>Summary Plan Description</I> for a more complete description of the Plan&#146;s provisions, a copy of which is available from National Oilwell Varco, L.P. a wholly owned subsidiary of National
Oilwell Varco, Inc. (collectively the &#147;Company&#148;). </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>General </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Plan was established effective April&nbsp;1, 1987, for the benefit of the employees of the Company. The Plan is a defined contribution plan covering
substantially all domestic employees who have completed one hour of service. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Contributions </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Participants may make both pretax and
after-tax contributions to the Plan. The Plan allows pretax salary deferral contributions of 1% to 100% (less any after-tax contributions, required withholdings, or other elected deductions) of compensation, subject to certain Internal Revenue
Service (IRS) limitations. The Plan allows participants to designate their salary deferral contributions as Roth contributions. After-tax contributions may be made at 1% to 18% of eligible compensation. However, combined pretax and after-tax
contributions, required withholdings, and other elected deductions cannot exceed 100% of compensation. The Plan provides for the automatic enrollment and payroll deduction of 4% of a new eligible employee&#146;s compensation as soon as practical
following 60 days after employment. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Company matches 100% of the first 4% of each participant&#146;s contribution. The Company may also make a
discretionary contribution (the Employer Retirement Contribution) to the Plan. The amount of the Employer Retirement Contribution is determined based upon participants&#146; eligible salary and years of service. Participants age 50 and older may
contribute additional pretax catch-up contributions, subject to IRS limitations. For the year ended December&nbsp;31, 2015, the Company contributed $41,372,069 of Employer Retirement Contributions. Participants must have completed one year of
service in order to receive Company matching and Employer Retirement Contributions. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Each participant may direct the trustee to invest both the
participant&#146;s and the Company&#146;s contributions in one or more of the investment options offered by the Plan. Effective December&nbsp;31, 2015, the NOV Stock Fund (the &#147;Stock Fund&#148;) will no longer be an available option when
investing new participant contributions or reallocating existing funds within the Plan. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Vesting </B></P>

that permits participants to borrow a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of the total value of their Plan assets. The loans are payable in principal installments, plus interest, at prime plus one percent through
payroll deductions and are due in one- to five-year terms, unless the loan is used to acquire a principal residence, in which case the loan term cannot exceed ten years. Repayments are made ratably through payroll deductions. </P>

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 recorded as administrative expenses and are expensed when they are incurred. No
allowance for credit losses has been recorded as of December&nbsp;31, 2015 or 2014. 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>Administrative Expenses </B></P>

investment contracts) are stated at fair value. Fair value is defined as 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 (an exit price).
See Note&nbsp;3 for further discussion of fair value measurements. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Purchases and sales of securities are recorded on a trade-date basis. Interest income

investments in various investment securities that, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility 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 the amounts reported in the statements of net assets available for benefits and participant account balances. </P>

2015-07). ASU 2015-07 removes the requirement to categorize within the fair value hierarchy investments for which fair values are estimated using the net asset value (NAV) practical expedient provided by Accounting Standards Codification 820, Fair
Value Measurement (ASC 820). Disclosures about investments in certain entities that calculate NAV per share are limited under ASU 2015-07 to those investments for which the entity has elected to estimate the fair value using the NAV practical
expedient. ASU 2015-07 is effective for entities (other than public business entities) for fiscal years beginning after December&nbsp;15, 2016, with retrospective application to all periods presented. Early application is permitted. Management has

Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965): (Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient. Part I of
the ASU eliminates the requirements to measure the fair value of fully benefit-responsive investment contracts and provide certain disclosures. Contract value is the only required measure for fully benefit-responsive investment contracts. Part II of
the ASU eliminates the requirements to disclose individual investments that represent 5 percent or more of net assets available for benefits and the net appreciation or depreciation in fair value of investments by general type. It also simplifies
the level of disaggregation of investments that are measured using fair value. Plans will continue to disaggregate investments that are measured using fair value by general type; however, plans are no longer required to also disaggregate investments
by nature, characteristics and risks. Further, the disclosure of information about fair value measurements shall be provided by general type of plan asset. Part III of the ASU is not applicable to the Plan. The ASU is effective for fiscal years
beginning after December&nbsp;15, 2015. Parts I and II are to be applied retrospectively. Management has elected to adopt Parts I and II of the ASU early. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>4. Fully Benefit-Responsive Investment Contracts </B></P>
 <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Plan offers an investment called the National Oilwell Varco Stable Value Fund, which is managed by Galliard Capital Management and is
comprised of investments in fixed income security funds that are covered by synthetic guaranteed investment contracts (synthetic GICs), which are fully benefit-responsive investment contracts. Within this structure, the Plan owns both the fixed
income security funds and the wrapper contracts. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In a synthetic GIC structure, the Plan makes investments in fixed income security funds. To reduce the
risk of losses on these investments, the Plan purchases a wrapper contract from an insurance company or bank, which enables Plan participants to transact at a specified contract value by protecting the principal amount invested over a specific
period of time. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Fully Benefit-Responsive investment contracts held by a defined contribution plan are required to be reported at contract value. Contract
value is the relevant measurement attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. The contract
value of the fully benefit-responsive investment contracts represents contributions plus earnings, less participant withdrawals and administrative expenses. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Plan&#146;s investments covered by the wrapper contracts earn interest at interest crediting rates that are typically reset on a monthly or quarterly
basis. These interest crediting rates use a formula that is based on the characteristics of the underlying fixed income portfolio. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Participants may
ordinarily direct the withdrawal or transfer of all or a portion of their investment at contract value. Certain events limit the ability of the Plan to transact at contract value with the issuer. Such events include the following:
(i)&nbsp;amendments to the Plan documents (including complete or partial Plan termination or merger with another plan), (ii)&nbsp;changes to the Plan&#146;s prohibition on competing investment options or deletion of equity wash provisions, or
(iii)&nbsp;bankruptcy of the Plan sponsor or other Plan sponsor events (e.g.,&nbsp;divestitures or spin-offs of the trust to qualify for exemption from federal income taxes or any required prohibited transaction exemption under ERISA). The Plan
administrator does not believe that the occurrence of any such value event, which would limit the Plan&#146;s ability to transact at contract value with participants, is probable. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In some cases, an investment contract issuer may terminate a contract with the Plan and settle at amounts different from the contract value. Examples of these
events include the Plan&#146;s loss of its qualified status, material breaches of responsibilities that are not cured, or material and adverse changes to the provisions of the Plan. If one of these events were to occur, the investment contract
issuer could terminate the contract at the market value of the underlying investments. </P>

Trust Company, which is a direct filing entity with the U.S. Department of Labor. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Wells Fargo Short Term Investment Fund S is a common collective

 <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Certain investments of the Plan are managed by Wells Fargo, N.A., the trustee of the Plan; therefore, these transactions qualify as
party-in-interest transactions. Additionally, a portion of the Plan&#146;s assets are invested in the Company&#146;s common stock. Because the Company is the plan sponsor, transactions involving the Company&#146;s common stock qualify as
party-in-interest transactions. All of these transactions are exempt from the prohibited transactions rules under ERISA. </P>

 <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Plan has received a determination letter from the IRS dated May&nbsp;12, 2014, stating that the Plan is qualified under
Section&nbsp;401(a) of the Internal Revenue Code (IRC) and; therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the IRC to maintain its qualified status. The plan sponsor believes
the Plan is being operated in compliance with the applicable requirements of the IRC and; therefore, believes that the Plan is qualified and the related trust is tax-exempt. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">U.S. generally accepted accounting principles require plan management to evaluate uncertain tax positions taken by the Plan. The financial statement effects
of a tax position are recognized when the position is more likely than not, based on the technical merits, to be sustained upon examination by the IRS. The plan administrator has analyzed the tax positions taken by the Plan and has concluded that,
as of December&nbsp;31, 2015, there are no uncertain positions taken or expected to be taken. The Plan has recognized no interest or penalties related to uncertain tax positions. The Plan is subject to routine audits by taxing jurisdictions;
however, there are currently no audits for any tax periods in progress. The plan administrator believes it is no longer subject to income tax examinations for years prior to 2012. </P>
