Notes to Financial Statements

Employees are automatically enrolled after a 60-day opt out period. The Employer withholds an amount equal to a percentage of eligible employee compensation (other than bonus pay), until such time as the employee changes or stops the contribution.

Effective January 1, 2013, the new hire automatic enrollment percentage increased from 3% to 6% of employee compensation (other than bonus pay) for non-union employees hired or rehired after January 1, 2013. Newly hired employees covered under a collective bargaining agreement, will be automatically enrolled at 3%.

Effective January 1, 2013, current employees who did not elect to make deferral contributions prior to December 31, 2012, were automatically enrolled at a 3% deferral percentage, and participants who were enrolled and contributing were automatically increased to a 3% deferral percentage if the participant was contributing at a rate that was less than 3%, until such time as the employee changes or stops the contribution.

An automatic increase feature became effective January 1, 2014 whereby the contribution percentage is increased by 1% per year up to a maximum contribution percentage of 6% for participants making a contribution of less than 6%, unless the employee changes or stops the contribution. The automatic increase does not apply to employees who are covered by a collective bargaining agreement.

The deferred profit sharing portion of the Plan is a non-contributory, defined contribution plan funded by discretionary Employer contributions as determined under the provisions of the Plan, which are generally based on years of service and consolidated profits as determined by the Employer.

Participant Accounts

Individual participant accounts are maintained by Principal and are credited with employee contributions, Employer contributions, and Plan earnings in the case of the 401(k) portion of the Plan and allocations of Employer contributions, Plan earnings, and forfeitures of former participants’ non-vested amounts in the case of the deferred profit sharing portion of the Plan. Allocations of contributions and forfeitures in the deferred profit sharing portion of the Plan are based upon compensation and years of service, as defined, while allocations of earnings are recognized by changes in the unit value. Such accounts are valued periodically in accordance with the provisions of the Plan.

Notes to Financial Statements

Notwithstanding the foregoing, all amounts allocated or re-allocated to a participant shall vest irrevocably to that participant not later than five years after the end of the Plan year in which the amounts are allocated or re-allocated unless the participant has ceased before that time to be an employee. Immediate full vesting also occurs upon a participant’s death, total and permanent disability, permanent layoff, or attainment of normal retirement age of 60.

For the 401(k) portion of the Plan, participants are 100% vested immediately in Employer and employee contributions and allocated earnings thereon.

Forfeitures

For the deferred profit sharing portion of the Plan, the non-vested portion of a terminated participant’s account balance is allocated to other Plan participants after the former participant has five consecutive one-year service breaks. During 2015 and 2014, allocated forfeitures were $1,783 thousand and $873 thousand, respectively. As of December 31, 2015 and 2014, forfeited nonvested accounts totaled $1,045 thousand and $1,976 thousand, respectively.

Plan Benefits

For the deferred profit sharing portion of the Plan, participants are eligible to receive vested benefits based upon the most recent valuation of their account upon termination of service with the Employer. Under certain provisions of the Plan, a percentage of vested benefits may also be distributed after 10 continuous years of service and/or upon reaching age 55. Distributions of Plan benefits are made to eligible participants in one lump-sum payment. Only vested balances of a participant’s profit sharing contribution account as of December 31, 2007 are eligible for in-service withdrawals.

For the 401(k) portion of the Plan, upon retirement, death, disability or termination of service, benefits will be paid in the form of a lump-sum distribution. Certain other withdrawals are permitted in the event of financial hardship, as defined in the Plan agreement.

Notes Receivable From Participants

Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of their vested account balance excluding amounts related to the participant’s deferred profit sharing account. Participant note terms range from one to five years or up to 10 years for the purchase of a primary residence. The notes are secured by the balance in the participant’s account and bear interest at the then current prime plus 2% as determined by the Plan Administrator. Principal and interest is paid ratably through payroll deductions, not less frequently than quarterly. As of December 31, 2015 outstanding notes receivable had interest rates ranging from 4.25% to 10.25%.

Plan Termination

Although it has not expressed any intent to do so, the Employer has the right to terminate the Plan in whole or in part at any time subject to the provisions of ERISA. In the event the Plan is terminated, all participant accounts will become 100% vested and non-forfeitable.

Participant and Non-Participant Directed Investments

Participants may invest in Magna International Inc. Common Stock (Employer Securities). For the deferred profit sharing portion of the Plan, 4/7 th  of the annual profit sharing contribution, as defined, is invested in Employer Securities, referred to as the non-participant-directed portion of the Plan. The remaining portion of the annual profit sharing contribution is directed by the employee and may include investments in Employer Securities. Prior to January 1, 2016, participants with a minimum of three years of service or upon attainment of age 55 may diversify up to 100% of Employer Securities held in their account. Effective January 1, 2016, participants may diversify up to 100% of Magna stock held in their account at any time.  Voting rights are all retained by the trustee per the direction of the Employer.

Administrative Expenses

The Employer administers the Plan. The Employer pays certain administrative expenses of the Plan and the Employer also provides certain administrative services, which have not been charged to the Plan. The amount of such expenses and cost of such services have not been determined. Certain administrative expenses not paid directly by the Employer may be paid from the Plan in accordance with ERISA provisions.

2.           Significant Accounting Policies

Basis of Financial Statements

The accompanying financial statements have been prepared under the accrual basis of accounting.

Use of Estimates

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Risks and Uncertainties

The Plan invests in various investment securities. Investment securities are exposed to various risks, such as interest rate, market 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 affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

Investment Valuation and Income Recognition

All Plan investments other than guaranteed investment contracts, are stated at fair value. Fair value is the price that would be received to sell an asset (an exit price) in the principal or most advantageous market for the asset in an orderly transaction between market participants on the measurement date. The Plan’s management determines the Plan’s valuation policies utilizing information provided by the investment advisors, Plan trustee and custodian. See Note 3 for discussion of fair value measurements.

9

The Magna Group of Companies Retirement Savings Plans

Notes to Financial Statements

Guaranteed investment contract s held by a defined contribution plan that are fully benefit responsive are reported at contract value. Contract value is the relevant measurement because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the contract. Contract value represents net contributions plus interest at the contract rate. See Note 5 for discussion of guaranteed investment contracts.

Purchases and sales of securities are recorded on a trade date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation (depreciation) includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

Notes Receivable - Participant Loans

Participant loans are classified as notes receivable from participants, and are measured at the unpaid principal balance plus unpaid accrued interest. Defaulted loans, if any, are reclassified as distributions based upon the terms of the Plan Document.

Concentration of Investments

Included in investments at December 31, 2015 and 2014 are shares of the Employer’s securities amounting to $275 million and $395 million, respectively. This investment represents 24% and 30% of total investments at December 31, 2015 and 2014, respectively. A significant decline in the market value of the Employer’s securities would significantly affect the net assets available for benefits.

Payment of Benefits

Benefits are recorded when paid.

Recent Accounting Pronouncements

In May 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2015-07, Disclosures for Investments in Certain Entities that Calculate Net Asset Value Per Share (or its Equivalent) (ASU 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 practical expedient provided by Accounting Standards Codification 820, Fair Value Measurement. Disclosures about investments in certain entities that calculate net asset value per share are limited under ASU 2015-07 to those investments for which the entity has elected to estimate the fair value using the net asset value practical expedient. ASU 2015-07 is effective for fiscal years beginning after December 15, 2015, with early adoption permitted.

In July 2015, the FASB issued Accounting Standards Update 2015-12, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965), (ASU 2015-12): (Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, Part III) Measurement Date Practical Expedient (ASU 2015-012). This three-part update simplifies current benefit plan accounting and requires (i) fully benefit-responsive investment contracts to be measured, presented, and disclosed only at contract value and accordingly removes the requirement to reconcile their contract value to fair value; (ii) benefit plans to disaggregate their investments measured using fair value by general

type, either on the face of the financial statements or in the notes to the financial statements; (iii) the net appreciation or depreciation in investments for the period to be presented in the aggregate rather than by general type, and removes certain disclosure requirements relevant to individual investments that represent five percent or more of net assets available for benefits. Further, the amendments in this update eliminate the requirement to disclose the investment strategy for certain investments that are measured using Net Asset Value (NAV) per share. These amendments are effective retrospectively for fiscal years beginning after December 15, 2015 and early adoption is permitted. This update also provides a practical expedient to permit employee benefit plans to measure investments and investment-related accounts as of the month-end that is closest to the plan’s fiscal year-end, when the fiscal period does not coincide with a month-end, while requiring certain additional disclosures. This portion of the update is effective prospectively for fiscal years beginning after December 15, 2015 and early adoption is permitted.

Plan management reviewed both ASU 2015-07 and ASU 2015-12, and decided to early adopt both standards as they believe it will simplify Plan accounting and its presentation in the financial statements. As such, the accounting and disclosures in these financial statements and notes follow ASU 2015-07 and ASU 2015-12. The adoption was applied retrospectively and certain reclassifications were made on the Statement of Net Assets Available for Benefits to present comparative statements and certain investment disclosures were revised or eliminated as a result of the adoption of the ASUs.

3.           Investments

In accordance with ASC 820, Fair Value Measurements and Disclosures, t he Plan utilizes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The three levels of the fair value hierarchy are described as follows:

Level 1 - Inputs to the valuation methodology are unadjusted quoted prices for identical assets in active markets.

Level 2 - Inputs to the valuation methodology include quoted prices for similar assets in active markets, quoted prices for identical or similar assets in inactive markets, other inputs that are observable or can be corroborated by observable market data.

Level 3 - Inputs to the valuation methodology are both significant to the fair value measurement and unobservable.

The following valuation methodologies were used to measure the fair value of the Plan’s investments. There have been no changes in the methodologies used at December 31, 2015 and 2014 other than the adoption of ASU 2015-12 as disclosed in Note 2.

The Principal Stable Value Fund: Daily valued by the trustee, Union Bond & Trust Company, based on the underlying investments which consist primarily of a diversified portfolio of stable value investment contracts issued by life insurance companies, banks and other financial institutions, the performance of which may be predicated on underlying fixed income investments. The Fund provides for daily redemptions at the reported NAV. Participants are permitted to redeem units at NAV on the valuation date.

11

The Magna Group of Companies Retirement Savings Plans

Notes to Financial Statements

Pooled Separate Accounts (PSAs): Valued based on the underlying investments (i.e., common stock, mutual funds, short term securities). While the majority of the underlying assets values are based on quoted prices, the net asset value (NAV) of the pooled separate account is not publicly quoted. The NAV is reported by the fund managers as of the financial statement date based on recent transaction prices. The PSAs held by the Plan provide for daily redemptions by the Plan at reported NAV with no advance notice requirement. The Plan is permitted to redeem investment units at NAV on the measurement date. Principal may place transfer or liquidation restrictions on the U.S. Property Separate Account. No such restrictions were in place during 2015 and 2014. Generally, the PSA investments in any class can be transferred once every 30 days at the current NAV per share based on the fair value of the underlying assets. Participants are not allowed to transfer back into that originating class until the 30-day period has expired.

Common/Collective Trusts (CCTs): Valued at the net asset value (NAV) of the units held by the Plan which are based on the quoted market prices of the underlying securities of the funds. The unit price is based on the value of the underlying investment assets owned by the fund, minus its liabilities, and then divided by the number of shares outstanding.

Employer Securities: Valued at the closing price quoted on a recognized securities exchange on the last business day of the Plan year.

Mutual Funds: Valued at quoted market prices of shares held by the Plan.

Life Insurance Policies: Valued at the cash surrender value of the individual policies.

The Plan’s valuation methods may result in a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Although Plan management believes the valuation methods are appropriate and consistent with the 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.

4.           Non-Participant-Directed Investments

The Magna International Inc. Common Stock includes both participant and non-participant-directed investments, which are co-mingled. Substantially all contributions and associated appreciation (depreciation), income and dividends are non-participant-directed until amounts are available for transfer as described in the Plan agreement. Information about the net assets available for benefits and the significant components of the changes in net assets available for benefits for non-participant-directed investments is as follows:

5.           Guaranteed Investment Contracts

The Plan invests in the Guaranteed Fixed Income Option Fund Contract (GFIO), a guaranteed investment contract. The GFIO is a benefit responsive contract entered into with Principal Life Insurance Company (Principal). Principal maintains the contributions in a general account. The account is credited with earnings on the underlying investments and charged for participant withdrawals and administrative expenses.

The GFIO is valued at contract value for presentation in the Plan’s assets. Contract value is the relevant measurement attribute for that portion of the net assets available for benefits attributable to fully benefit-responsive investment contracts because contract value is that amount participants would receive if they were to initiate permitted transactions under the terms of the Plan. Certain events that may limit the ability of the Plan to transact at contract value are not probable of occurring.

There are no reserves against contract value for credit risk of the contract issuer or otherwise. The crediting interest rate is a blended rate determined using a dollar-weighted average of all the Guaranteed Interest Rates of the Guaranteed Interest Funds under this contract. Under the terms of the existing contract, the interest rate can be reset on an annual or semiannual basis. The GFIO is a single group annuity contract with a fixed rate of interest. The average yield earned by the plan and credited to participants was 0.92% and 1.38% during 2015 and 2014, respectively.

6.           Related Party Transactions

Certain Plan investments are shares of guaranteed investment contracts, stable value fund, common/collective trusts, pooled separate accounts and mutual funds managed by Principal. Principal is the trustee as defined by the Plan and qualifies as a party-in-interest. The Plan also invests in the stock of the Employer.

7.           Income Tax Status

The Plan has received a determination letter from the Internal Revenue Service dated September 4, 2012 stating that the Plan is qualified under Section 401(a) of the Code and, therefore, the related trust is exempt from taxation. The Plan is required to operate in conformity with the Code to maintain its qualification. The Plan document has been amended since receiving the determination letter. However, the Plan Administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes the Plan, as amended, is qualified and the related trust is tax exempt.

Accounting principles generally accepted in the United States of America require plan management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the Internal Revenue Service. The Plan administrator has analyzed the tax positions taken by the Plan and has concluded that as of December 31, 2015, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. 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.

8.           Plan Transfers

Effective September 1, 2015 all Magna Interiors operations were sold and the respective participant accounts (including loans) approximately $95.3 million were transferred to the new employer’s plan.

Effective September 1, 2015 Magna sold the majority stake in Bestop, which subsequently became a joint venture. The respective participant accounts (including loans) approximately $10.1 million were transferred to the new employer’s plan.

Effective May 5, 2015 Magna sold the Magna Steyr Battery Systems division. Participants from the aforementioned division were terminated and had the option to voluntarily transfer their accounts .

Effective June 2, 2014, New Process Gear, Inc. became a participating Employer in the Plan and the New Process Gear, Inc. Deferred Pay Plan for UAW-Represented Employees (NPG Plan) was merged into the Plan. As a result, there was a transfer of approximately $10.2 million from the NPG Plan to the Plan on June 2, 2014.

The Employer failed to remit certain employee deferrals and loan repayments to the Plan in a timely manner according to DOL regulations during 2015 and 2014 aggregating $2,119 thousand and $781 thousand, respectively. The Employer has calculated lost earnings and deposited the lost earnings into the Plan for 2015 and 2014.
