REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Administrative Committee

AptarGroup, Inc. Profit Sharing and Savings Plan

Crystal Lake, Illinois

We have audited the accompanying statements of net assets available for benefits of the AptarGroup, Inc. Profit Sharing and Savings Plan (the “Plan”) as of December 31, 2015 and 2014, and the related statement of changes in net assets available for benefits for the year ended December 31, 2015.  These financial statements are the responsibility of the Plan’s management.  Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted 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.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.  An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2015 and 2014, and the changes in net assets available for benefits for the year ended December 31, 2015 in conformity with U.S. generally accepted accounting principles.

The supplemental Schedule H, Line 4i - Schedule of Assets (Held at End of Year) as of December 31, 2015 has been subjected to audit procedures performed in conjunction with the audit of AptarGroup, Inc. Profit Sharing and Savings Plan’s financial statements.  The supplemental schedule is the responsibility of the Plan’s management.  Our audit procedures included determining whether the information presented in the supplemental schedule 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 supplemental schedule, we evaluated whether the supplemental schedule, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.  In our opinion, the supplemental schedule is fairly stated in all material respects in relation to the financial statements as a whole.

NOTE 1 - DESCRIPTION OF THE PLAN

General Plan Information

The following description of the AptarGroup, Inc. Profit Sharing and Savings Plan (the “Plan”) provides only general information.  Participants should refer to the plan document for a more complete description of the Plan’s provisions.

The Plan, established on April 22, 1993, is a participant-directed defined contribution plan which covers eligible full-time and part-time non-union employees of AptarGroup, Inc. and certain of its subsidiaries (the “Company” or the “Employer”).  The Plan is administered by a committee appointed by the Company, consisting of Company employees.

A participant (“Participant” or “Participants”) is a full-time employee who becomes eligible to participate on the first day of the month following 30 days of service, or a part-time employee who becomes eligible to participate after completion of 1,000 hours of service in a defined twelve-month period.  If an employee has not enrolled in the Plan within 30 days from the eligibility date, the employee will be automatically enrolled, deferring at 3% of eligible compensation, unless the employee elects to not participate in the Plan.  A Participant can authorize contributions of salary to the Plan of not less than 1 percent and not more than 25 percent of earnings (subject to Internal Revenue Code (“IRC”) limitations).  Contributions can be traditional pre-tax, Roth after-tax, or a combination of the two contribution types.  Each Participant who was age 50 or older by the end of 2015 was also permitted under the IRC and the Plan to contribute an additional $6,000 in tax-deferred catch-up contributions.  Participants’ earnings are generally defined as total compensation for services rendered to the Employer.  Participants may elect to suspend their contributions at any time.  Eligible employees will not share in any Employer contributions for any period in which they voluntarily suspend their contributions or do not participate in the Plan.  Active participation can be elected again at any time.

Contributions

The amount of Employer contributions is determined annually by the Employer on a discretionary basis.  Such contributions are computed as a matching percentage of each Participant’s contribution within specified limits.  The Company matched 50% of Participant contributions up to the first 6% of eligible compensation deferred, for the year ended December 31, 2015.

Plan Investments

Fidelity Management Trust Company (the “Trustee”) is the trustee for the Plan.  Participants may direct their contributions and the employer matching contribution to any combination of investment options offered by the Plan.

NOTE 1 - DESCRIPTION OF THE PLAN (Continued)

Participant Accounts

A Participant may elect to transfer certain portions of his or her account in the Plan from one fund to another up to twelve times per year subject to certain restrictions between the Retirement Government Money Market Portfolio and Managed Income Portfolio.  Each Participant’s account is credited with contributions and an allocation of plan earnings, and reduced for benefit payments and certain administrative expenses.  Plan earnings are determined and credited to each Participant’s account on a daily basis in accordance with the proportion of a Participant’s account to all accounts.

Vesting

Each Participant is fully vested in his or her contributions and related earnings at all times.  Vesting of the Employer contribution account occurs at the rate of 20 percent per year of service on a cumulative basis for each year of service with a participating Employer.  When a Participant terminates employment for any reason other than retirement after age 65, death or disability, the nonvested amounts of the Employer contributions will be forfeited and used to reduce administrative expenses of the Plan and then used to reduce future contributions of the Employer.  The amount of such forfeitures available to reduce future contributions of the Employer was $124,560 and $110,478 as of December 31, 2015 and 2014, respectively.  When a terminated Participant’s vested balance is $5,000 or less, the Participant is required to take a lump-sum distribution of the benefit.

Nonvested amounts for Participants who terminate employment for any reason other than retirement after age 65, death or disability, will be reinstated if re-employment by the Employer occurs prior to incurring five consecutive one year breaks in service as defined by the Plan agreement.

Payment of Benefits

Participants may elect to receive vested benefits in the form of a lump-sum cash distribution, installment payments (for account portion attributable to Pittway Blue Chip Plan), or a combination of these forms (for account portion attributable to Pittway Blue Chip Plan), or a direct rollover transfer to an eligible retirement plan.  While employed, in the event of hardship, Participants may withdraw a portion of their vested account balances as defined by the Plan.  The Plan allows for in-service withdrawals for Participants that have attained age 59.5.  Upon withdrawal from the Plan, the Participant will receive the amount of his or her contributions plus the vested portion of his or her Employer contributions.

NOTE 1 - DESCRIPTION OF THE PLAN (Continued)

Notes Receivable from Participants

The Plan provides that a Participant may, for specified reasons, borrow from the Plan an amount not to exceed the lesser of 50 percent of the Participant’s vested account balance or $50,000.  Each Participant loan is evidenced by a note and each Participant note carries an interest rate equal to the prime rate plus one percent (loans opened during the year ended December 31, 2015 had interest rates on outstanding notes of 4.25%) charged by the Trustee on the date of the loan. Repayment occurs through payroll withholding over a period not to exceed 60 months or up to 120 months if the loan has been used to purchase the primary residence of the Participant.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting

The financial statements of the Plan have been prepared on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles.

Valuation of Investments

The Plan’s investments are stated at fair value.

Contributions

Employer and Participant contributions are invested directly in appropriate funds based upon Participant elections made at the date of enrollment or through authorized changes in elections.

Rollover Contributions

Participant contributions included in the Statement of Changes in Net Assets Available for Benefits in the amount of $1,373,572 were transferred to the Plan as a result of the Participant rollover provision of the Plan during 2015.

Payment of Benefits

Benefits are recorded when paid.

Notes Receivable from Participants

Notes receivable from participants are reported at their unpaid principal balance plus any accrued but unpaid interest, with no allowance for credit losses, as repayments of principal and interest are received through payroll deductions and the notes are collateralized by the Participants’ account balances.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of net assets and changes thereto.  Actual amounts could differ from those estimates.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Security Transactions and Investment Income

Purchases and sales of securities, including related gains and losses, are recorded as of the trade date.  Unsettled security investments represent transactions entered into prior to the end of the accounting period for which cash settlement is made in a subsequent period.  Interest income is recorded when earned.  Dividend income is recorded on the ex-dividend date.  In accordance with the policy of stating investments at current value, net appreciation or depreciation is reflected in the Statement of Changes in Net Assets Available for Benefits.  This net appreciation or depreciation consists of realized and unrealized gains and losses.  Realized losses and gains are calculated as the difference between proceeds from a sales transaction and cost determined on an average basis.  Unrealized losses and gains are calculated as the change in the fair value between the beginning of the year (or purchase date if later) and the end of the year.

Trustee and Administrative Expenses

Expenses incurred in the administration of the Plan and Marquette Investment Manager fees are paid by the Plan through plan forfeitures, except for loan service fees, which are paid by the Participants.  Certain other costs of plan administration were paid by the Company.

Adoption of Recent Accounting Pronouncements

In May 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-07, “Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share” (“ASU 2015-07”), which removes the requirement to present certain investments for which the practical expedient is used to measure fair value at net asset value within the fair value hierarchy table. Instead, an entity would be required to include those investments as a reconciling item so that the total fair value amount of investments in the disclosure is consistent with the fair value investment balance on the statement of net assets available for benefits. The Company elected to early adopt ASU 2015-07 as of December 31, 2015, as permitted and has applied this ASU 2015-07 retrospectively, as required. The Plan presents the investment disclosure required by this ASU 2015-07 in the fair value hierarchy tables for 2015 and 2014 in Note 3, “Fair Value Measurements.” There were no other impacts on the statements of net assets available for benefits and the statement of changes in net assets available for benefits as of December 31, 2015 and December 31, 2014.

Adoption of Recent Accounting Pronouncements (Continued)

In July 2015, the FASB issued ASU No. 2015-12, “Plan Accounting: Defined Benefit Pension Plans (Topic 960), 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,” (“ASU 2015-12”), which simplifies the required disclosures related to employee benefit plans. Part I clarifies that a plan’s investments in stable value collective trust funds are not fully benefit-responsive investment contracts and should be measured and presented only at fair value. Part II requires plans to 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. Furthermore, the disclosure of information about fair value measurements shall be provided by general type of plan asset. Part III is not applicable to the Plan. ASU 2015-12 is effective for fiscal years beginning after December 15, 2015, with early adoption permitted.  The Company elected to early-adopt ASU 2015-12 as of December 31, 2015, and has applied the provisions retrospectively.  The adoption of ASU 2015-12 has resulted in the reclassification of $95,626 related to the adjustment from fair value to contract value for fully benefit-responsive investment contracts within investments, at fair value in the Statement of Net Assets Available for Benefits as of December 31, 2014.  Furthermore, the Company has eliminated the historical disclosure of individual investments which comprise 5% or more of total net assets available for benefits, as well as the net appreciation or depreciation of fair values by type. There were no other impacts on the statements of net assets available for benefits as of December 31, 2015 and December 31, 2014.

NOTE 3 - FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received by the Plan for an asset or paid by the Plan to transfer a liability (an exit price) in an orderly transaction between market participants on the measurement date in the Plan’s principal or most advantageous market for the asset or liability.  There has been established a fair value hierarchy which requires the Plan to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.  The hierarchy places the highest priority on unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurements) and gives the lowest priority to unobservable inputs (Level 3 measurements).  The three levels of inputs within the fair value hierarchy are defined as follows:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Plan has the ability to access as of the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs that reflect the Plan’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

In some cases, a valuation technique used to measure fair value may include inputs from multiple levels of the fair value hierarchy.  The lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy.

The following descriptions of the valuation methods and assumptions used by the Plan to estimate the fair value of investments apply to investments held directly by the Plan:

Company common stock:  The fair values of AptarGroup, Inc. common stock are determined by obtaining quoted prices from a nationally recognized exchange (Level 1 inputs).

Mutual funds:  The fair values of mutual fund investments are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs).

Money market deposit accounts:  Fair values of money market deposit account balances have been determined based upon their quoted redemption prices and recent transaction prices of $1.00 per share (Level 2 inputs), with no discounts for credit quality or liquidity restrictions.

Stable value fund:  The fair values of participation units in the stable value collective trust are based upon the net asset values of such fund.  Units of participation are redeemable upon receipt of unitholder’s instruction based on the next determined net asset value per unit.  Net asset value per unit is determined each business day.

NOTE 3 - FAIR VALUE MEASUREMENTS (Continued)

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values.  Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other 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.

Investments measured at fair value on a recurring basis are summarized below:

(a) In accordance with Subtopic 820-10, certain investments that were measured at net asset value per share (or its equivalent) have not been classified in the fair value hierarchy.  The fair value amounts presented in the above tables are intended to permit reconciliation of the fair value hierarchy to the line items presented in the statement of net assets available for benefits.

There were no transfers between Level 1 and Level 2 investments during 2015.

NOTE 4 - PARTY-IN-INTEREST TRANSACTIONS

Parties-in-interest are defined under Department of Labor regulations as any fiduciary of the Plan, any party rendering services to the Plan, the Company, and certain others.  Party-in-interest transactions included investments in the AptarGroup Stock Fund.  At December 31, 2015 and 2014, the Plan had $26,660,235 and $28,116,514, respectively, invested in Employer Stock through a unitized investment fund managed by the Trustee.  The Plan held 366,968 and 420,654 shares of Employer stock as of December 31, 2015 and 2014, respectively.  Dividends were paid on these shares in the amount of $470,895 during the year ended December 31, 2015.  These transactions also qualify as party-in-interest transactions.

Additionally, certain plan investments are shares of mutual funds or collective trusts managed by the Trustee or an affiliate of the Trustee; therefore, these transactions qualify as party-in-interest.  Notes receivable from participants also reflect party-in-interest transactions.  Fees paid by the participants to the Trustee for loan services and other participant-initiated transactions amounted to $26,518 for the year ended December 31, 2015.  Fees paid by the Plan through plan forfeitures to the Trustee and Marquette Investment Manager for trustee and investment management fees amounted to $28,284 and $26,500, respectively, for the year ended December 31, 2015.  These transactions are not prohibited transactions as defined under the Employee Retirement Income Security Act of 1974 (“ERISA”).

NOTE 5 - FEDERAL INCOME TAX STATUS

The Internal Revenue Service has determined and informed the Company by a letter dated June 27, 2014 that the Plan is designed in accordance with applicable sections of the IRC.  The Plan has been amended since receiving the determination letter.  However, the Plan administrator believes that the Plan is designed and continues to be operated in compliance with the applicable requirements of the IRC.  Therefore, no provision for income taxes has been included in the Plan’s financial statements.

Accounting principles generally accepted in the United States of America require plan management to evaluate tax positions taken by the Plan.  The plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2015 and 2014, 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 authorities; 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.

NOTE 6 - RISKS AND UNCERTAINTIES

Investment securities are exposed to various risks, such as interest rate, market, liquidity, and credit.  Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect Participants’ account balances and the amounts reported in the Statements of Net Assets Available for Benefits and the Statement of Changes in Net Assets Available for Benefits.

The Plan allows Participants to invest in the common stock of the Plan Sponsor, AptarGroup, Inc. The Plan’s investment in the common stock of the Plan Sponsor was 16.5% and 17.4% of plan investments as of December 31, 2015 and 2014, respectively.

NOTE 7 - AMENDMENT AND TERMINATION OF PLAN

The Plan may be amended at any time by the Company.  However, no amendment may adversely affect the current rights of the Participants in the Plan with respect to contributions made prior to the date of the amendment.

Although it has not expressed any intent to do so, the Company reserves the right to discontinue Employer contributions or to terminate its participation in the Plan at any time.  In the event of a partial or complete termination of the Plan, all Participants with respect to whom the Plan is being terminated shall be fully vested in their accounts as of the date of the termination of the Plan.

The Plan is subject to the provisions of ERISA applicable to defined contribution plans.  Since the Plan provides for an individual account for each Participant and for benefits based solely on the amount contributed to the Participant’s account and any income, expenses, gains and losses attributed thereto, its benefits are not insured by the Pension Benefit Guaranty Corporation pursuant to Title IV of ERISA.
