PART I

ITEM 1. BUSINESS

Organization and Background

Mills Music Trust (the “Trust”) was created by a Declaration of Trust, dated December 3, 1964 (the “Declaration of Trust”), for the purpose of acquiring from Mills Music, Inc. (“Old Mills”), the right to receive payment of a deferred contingent purchase price obligation (the “Contingent Portion”) payable to Old Mills. The obligation to pay the Contingent Portion arose as the result of the sale by Old Mills of its music and lyric copyright catalogue (the “Catalogue”) to a newly formed company pursuant to an asset purchase agreement dated December 5, 1964 (the “Asset Purchase Agreement”). Pursuant to the Asset Purchase Agreement, payment of the Contingent Portion to the Trust continues until the end of the year in which the last copyright in the Catalogue expires and cannot be renewed.

The Contingent Portion amounts are currently payable by EMI Mills Music Inc. (“EMI”), the owner of the copyrighted materials contained in the Catalogue. The Trust has been advised that Sony/ATV Music Publishing LLC (“Sony/ATV”) is the administrator and manager of EMI and the Catalogue.

HSBC Bank, USA, N.A. is the Corporate Trustee of the Trust (the “Corporate Trustee”), and Lee Eastman and Michael E. Reiss are the Individual Trustees of the Trust (the “Individual Trustees” and together with the Corporate Trustee, the “Trustees”).

Proceeds from Contingent Portion Payments

The Trust receives quarterly payments of the Contingent Portion from EMI and distributes the amounts it receives to the registered owners of Trust Certificates (the “Unit Holders”) representing interests in the Trust (the “Trust Units”), after payment of, or withholdings in connection with, expenses and liabilities of the Trust. The Declaration of Trust provides that these are the Trust’s sole responsibilities and that the Trust is prohibited from engaging in any business activities.

Payments of the Contingent Portion to the Trust are based on royalty income which the Catalogue generates. The Trust does not own the Catalogue or any copyrights or other intellectual property rights and is not responsible for collecting royalties in connection with the Catalogue. As the current owner and administrator of the Catalogue, EMI is obligated under the Asset Purchase Agreement to use its best efforts to collect all royalties, domestic and foreign, in connection with the Catalogue and to remit a portion of its royalty income to the Trust as its Contingent Portion payment obligation, in accordance with the terms of the Asset Purchase Agreement.

Calculation of the Contingent Portion

The amount of each payment of the Contingent Portion is based on a formula set forth in the Asset Purchase Agreement. For information regarding the calculation of the Contingent Portion and a related dispute between EMI and the Trust see “Contingent Portion Payments” under Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”.

Cash Distributions to Unit Holders

The Declaration of Trust provides for the distribution to the Unit Holders of all funds the Trust receives after payment of, or withholdings in connection with, expenses and liabilities of the Trust.

The Copyright Catalogue

The Catalogue is estimated to be composed of over 25,000 music titles (the “Copyrighted Songs”), of which approximately 1,600 produced royalty income in recent years. Based on information which EMI provided to the Trust, most of the royalty income generated by the Catalogue during recent years has been produced by a relatively small number of the Copyrighted Songs with copyrights established prior to 1960.

Table of Contents

EMI has provided the Trust with a listing (the “2015 Listing”) of the top 50 earning songs in the Catalogue during the 2015 calendar year (the “Top 50 Songs”). The totals contained in the right most column of the 2015 Listing represent gross royalty payments EMI received for the Top 50 Songs, before it made deductions in accordance with the Asset Purchase Agreement. The 2015 Listing also contains the following additional information for each song title: the writer(s), the original copyright date and copyright renewal date and the date on which each copyright enters the public domain in the United States.

The 2015 Listing is set forth below in the form that EMI provided to the Trust. There can be no assurance that the 2015 Listing is indicative of the future performance of the Copyrighted Songs or that EMI will be able to retain its rights to the Copyrighted Songs during their full term of copyright protection. As of the date of this report, the Trust has not undertaken an audit to confirm the accuracy of the information contained in the 2015 Listing, and there can be no assurance by the Trust that the information EMI provided in the 2015 Listing is correct.

(*) EMI has informed the Trust that there are three different copyrights associated with Down Hearted Blues.

(**) EMI advised the Trust that it has been unable to locate the 1980 renewal registration for Graduation Ball (Arrangement), and that it is therefore not possible to determine whether or not the song has entered the public domain.

(***) The Irish Suite consists of six movements, each containing its own copyright information as indicated. The Rakes of Mallow is scheduled to enter the public domain 95 years after the death of its author.

Accounting Policies

EMI typically makes payments to the Trust of the Contingent Portion in March, June, September and December for the prior calendar quarter. The payments received are accounted for on a cash basis, as are expenses of the Trust. The Declaration of Trust provides for the distribution of the amounts it receives in Contingent Portion payments to the Unit Holders after payment of, or withholdings in connection with, expenses and liabilities of the Trust.

The Trust’s financial statements reflect only cash transactions and do not include transactions that would be recorded in financial statements presented on the accrual basis of accounting, as contemplated by generally accepted accounting principles in the United States. The Trust does not prepare a balance sheet or a statement of cash flows.

ITEM 1A. RISK FACTORS

The Trust is a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and is not required to provide the information under this item.

ITEM 1B. UNRESOLVED STAFF COMMENTS

ITEM 2. PROPERTIES

The Trust does not own any property. The administrative office of the Trust is located at the offices of the Corporate Trustee, HSBC Bank, USA, N.A., Corporate Trust Issuer Services, 452 Fifth Avenue, New York, New York 10018. Except for fees paid to the Corporate Trustee in accordance with the Declaration of Trust, no expense is being charged or paid by the Trust for the office space and office equipment of the Corporate Trustee that is being utilized for the Trust. See Note 3, “Related Party Transactions,” under Part II, Item 8, “Financial Statements and Supplementary Data” for information regarding payments by the Trust to the Trustees.

ITEM 3. LEGAL PROCEEDINGS

The Trust filed a Summons with Notice on October 4, 2013 with the Supreme Court of the State of New York seeking damages of not less than $2,614,948 from EMI (the “Summons with Notice”) in connection with certain disputed matters discussed in the Trust’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013.

On February 28, 2014, the Trust, EMI and EMI Consortium Music Publishing Inc. agreed to settle (the “Settlement”) all disputed claims (the “Settled Claims”) of the Trust and EMI for all periods of time prior to October 1, 2011 (the “Settlement Period”). Pursuant to the Settlement, EMI paid the Trust the amount of $625,000 in full and final settlement of the Settled Claims, and the Trust voluntarily discontinued the Summons with Notice without prejudice and without cost subject to the terms of the Settlement.

The Settlement does not cover any claims for any periods of time after the Settlement Period. As such, the Trust has not agreed to settle any claims relating to certain Underpayments (as such term is defined below) which arose after the Settlement Period, and has not agreed on the method for calculating the Contingent Portion under the Asset Purchase Agreement. For information regarding the Underpayments see “Contingent Portion Payments” under Part II, Item 7, “Management’s Discussion and Analysis of Financial Conditions and Results of Operations.”

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION

The Copyright Catalogue

The Catalogue is estimated to be composed of over 25,000 music titles, of which approximately 1,600 produced royalty income in recent years. Based on the 2015 Listing, the Trust derives its receipts principally from copyrights established prior to 1958 in the Unites States. The receipts fluctuate based on consumer interest in the nostalgia appeal of older songs and the overall popularity of the songs contained in the Catalogue. The Catalogue also generates royalty income in foreign countries in which copyright is claimed.

A number of factors create uncertainties with respect to the Catalogue’s ability to continue to generate royalty income on a continuing, long-term basis for the Trust. These factors include: (i) the effect that foreign and domestic copyright laws and any changes thereto have or will have on renewal rights (e.g., vesting of renewal term rights), (ii) the length of the term of copyright protection under foreign and domestic copyright laws, (iii) reversionary rights that may effect whether EMI is able to retain its rights to the Copyrighted Songs during certain renewal terms (e.g., statutory termination of transfers or “copyright recapture”) and (iv) ongoing disputes regarding the payment and calculation of the Contingent Portion.

The Trust does not own the Catalogue or any copyrights or other intellectual property rights and is not responsible for collecting royalties in connection with the Catalogue. As the current owner and administrator of the Catalogue, EMI is obligated under the Asset Purchase Agreement to use its best efforts to collect all royalties, domestic and foreign, in connection with the Catalogue and to remit a portion of its royalty income to the Trust in accordance with its Contingent Portion payment obligation.

The Trust’s income is dependent, in part, on EMI’s ability to maintain its rights in the Copyrighted Songs through copyright protection. As the copyrights for the Copyrighted Songs expire, less royalty income will be generated, and the size of each payment of the Contingent Portion will be reduced accordingly.

Based on the 2015 Listing, the Top 50 Songs obtained copyright registration under the U.S. Copyright Act of 1909 (the “1909 Act”) between 1922 and 1958. For copyrighted works subject to the 1909 Act, copyright law generally provides for a possible 95 years of copyright protection, subject to certain factors, including the initial registration date of each copyright and compliance with certain statutory provisions including notice and renewal. The Copyright expiration dates for the Top 50 Songs range between 1997 and 2076, as set forth in the 2015 Listing.

The Copyrighted Songs are subject to statutory rights of termination of transfers, which may impact whether EMI is able to retain its ownership of the Copyrighted Songs during their respective terms of copyright protection. For copyrights governed by the 1909 Act, this termination right vests at the end of two different renewal terms, which vary for each Copyrighted Song. As the owner of the Catalogue, EMI (and not the Trust) is responsible for administrating the Catalogue and seeking renewals of the Copyrighted Songs. The Asset Purchase Agreement provides that EMI is obligated to use its best efforts to secure renewals.

Contingent Portion Payments

Payments of the Contingent Portion to the Trust are ordinarily made on a quarterly basis, approximately two to three months after a quarter ends. The Trust distributes the amounts it receives in Contingent Portion payments to the Unit Holders after payment of, or withholdings in connection with, expenses and liabilities of the Trust.

The amount of each payment of the Contingent Portion is based on a formula provided in the Asset Purchase Agreement. Prior to the first quarter of 2010, the Contingent Portion was calculated as an amount ranging from 65% to 75% of gross royalty income from the exploitation of the Catalogue for each quarterly period, less royalty expenses. In addition, the Contingent Portion was guaranteed to be at least a minimum of $167,500 per quarter (the “Minimum Payment Obligation”).

Table of Contents

Beginning with the first quarter of 2010, the Asset Purchase Agreement provides for certain changes with respect to the calculation of the Contingent Portion. One such change is that the Minimum Payment Obligation is no longer in effect. The Trust is also of the view that the Contingent Portion payable to the Trust changed to a fixed 75% of gross royalty income from the exploitation of the Catalogue for each quarterly period, less royalty related expenses (the “New Calculation Method”). However, EMI has disputed that the New Calculation Method is the correct interpretation of the Asset Purchase Agreement. As a result of EMI not applying the New Calculation Method, EMI’s payments of the Contingent Portion have been deficient, in the Trust’s view, by the following amounts (the “Underpayments”):

As of the date hereof, the Trust has not received the Underpayments, and EMI has expressly disagreed with the Trust. The Trust can offer no assurance that it will be able to recover any of the Underpayments or that it will resolve favorably the ongoing dispute relating to the New Calculation Method with respect to future payments of the Contingent Portion.

The Trust also asserted that even under EMI’s own interpretation of the formula set forth in the Asset Purchase Agreement governing calculation of the Contingent Portion payment to be made to the Trust in each quarterly period, EMI had over-deducted gross royalty income (the “EMI Error”) for the quarterly periods beginning with the third quarter of 2012 through the second quarter of 2014 and for the fourth quarter of 2014. In a letter dated July 15, 2015 EMI agreed with the Trust’s assessment, and on July 17, 2015 the Corporate Trustee confirmed receipt of an EMI payment to the Trust in the aggregate amount of $203,706, reflecting the cumulative amount of the EMI Error during the quarters ending with the fourth quarter of 2014.

The Trust has engaged Prager Metis CPAs, LLC to conduct a special audit of the books and records of EMI administered by Sony/ATV to resolve the ongoing dispute and also determine whether there have been any other material royalty omissions or expense over-deductions for the periods ending September 30, 2015.

Recent Payments

During the year ended December 31, 2015, the Trust received a total of $959,047 from EMI, $203,706 of which was attributable to the EMI Error discussed immediately above relating to periods prior to the fourth quarter of 2014. The remaining balance was attributable to ordinary Contingent Portion Payments which EMI made to the Trust during the 2015 calendar year.

During the year ended December 31, 2014, the Trust received a total of $1,365,103 from EMI, $625,000 of which was attributable to Settled Claims relating to periods prior to October 1, 2011. For more information regarding the Settled Claims see Part 1, Item 3, “Legal Proceedings.” The remaining balance was attributable to ordinary Contingent Portion Payments which EMI made to the Trust during the 2014 calendar year.

As noted in the paragraphs directly above, a portion of the distributions made in 2015 and 2014 were attributable to the EMI Error and Settled Claims, respectively. For computation details regarding the distributions made during the year ended December 31, 2015, please refer to the quarterly distribution report, dated December 28, 2015, attached as Exhibit 99.1 to the Current Report on Form 8-K, which the Trust filed with the Securities and Exchange Commission on December 28, 2015.

We have audited the accompanying statements of cash receipts and disbursements of Mills Music Trust for the years ended December 31, 2015 and 2014. These financial statements are the responsibility of the Trust’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 (U.S.). 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.

As described in Note 1 to the financial statements, these financial statements were prepared on the basis of cash receipts and disbursements, which is a comprehensive basis of accounting other than accounting principles generally accepted in the United States of America.

In our opinion, the financial statements referred to above present fairly, in all material respects, the cash receipts and disbursements of Mills Music Trust for the years ended December 31, 2015 and 2014, on the basis of accounting described in Note 1.

MILLS MUSIC TRUST

NOTES TO STATEMENT OF CASH RECEIPTS AND DISBURSEMENTS

TWO YEARS ENDED DECEMBER 31, 2015

NOTE 1. ACCOUNTING POLICIES AND GENERAL INFORMATION

Organization and Background

Mills Music Trust (the “Trust”) was created by a Declaration of Trust, dated December 3, 1964 (the “Declaration of Trust”), for the purpose of acquiring from Mills Music, Inc. (“Old Mills”), the right to receive payment of a deferred contingent purchase price obligation (the “Contingent Portion”) payable to Old Mills. The obligation to pay the Contingent Portion arose as the result of the sale by Old Mills of its music and lyric copyright catalogue (the “Catalogue”) to a newly formed company pursuant to an asset purchase agreement dated December 5, 1964 (the “Asset Purchase Agreement”). Pursuant to the Asset Purchase Agreement, payment of the Contingent Portion to the Trust continues until the end of the year in which the last copyright in the Catalogue expires and cannot be renewed.

The Contingent Portion amounts are currently payable by EMI Mills Music Inc. (“EMI”), the owner of the copyrighted materials contained in the Catalogue. The Trust has been advised that Sony/ATV Music Publishing LLC (“Sony/ATV”) is the administrator and manager of EMI and the Catalogue.

HSBC Bank, USA, N.A. is the Corporate Trustee of the Trust (the “Corporate Trustee”), and Lee Eastman and Michael E. Reiss are the Individual Trustees of the Trust (the “Individual Trustees” and together with the Corporate Trustee, the “Trustees”).

Proceeds from Contingent Portion Payments

The Trust receives quarterly payments of the Contingent Portion from EMI and distributes the amounts it receives to the registered owners of Trust Certificates (the “Unit Holders”) representing interests in the Trust (the “Trust Units”), after payment of, or withholdings in connection with, expenses and liabilities of the Trust. The Declaration of Trust provides that these are the Trust’s sole responsibilities and that the Trust is prohibited from engaging in any business activities.

Payments of the Contingent Portion to the Trust are based on royalty income which the Catalogue generates. The Trust does not own the Catalogue or any copyrights or other intellectual property rights and is not responsible for collecting royalties in connection with the Catalogue. As the current owner and administrator of the Catalogue, EMI is obligated under the Asset Purchase Agreement to use its best efforts to collect all royalties, domestic and foreign, in connection with the Catalogue and to remit a portion of its royalty income to the Trust as its Contingent Portion payment obligation, in accordance with the terms of the Asset Purchase Agreement.

Accounting Policies

Payments from EMI to the Trust of the Contingent Portion are typically made in March, June, September and December for the prior calendar quarter. The payments received are accounted for on a cash basis, as are expenses. The Declaration of Trust provides for the distribution of all funds received by the Trust to the Unit Holders after expenses are paid.

NOTE 3. RELATED PARTY TRANSACTIONS

The Trustees are paid in accordance with the Declaration of Trust, which provides that each Trustee shall receive annual compensation of $2,500, provided that such aggregate compensation to the Trustees as a group may not exceed 3% of the Contingent Portion amounts received by the Trust in any year. The Declaration of Trust also provides for the reimbursement of expenses reasonably incurred in the performance of a Trustee’s duties to the Trust, including clerical and administrative services. Accordingly, the Trustees are entitled to receive annual compensation and reimbursement for services performed for the Trust, including the Corporate Trustee’s services as the Registrar and Transfer Agent of the certificates representing the Trust Units. The Declaration of Trust also provides that if a Trustee performs unusual or extraordinary services, reasonable compensation for such services shall be paid, subject to the terms and conditions of the Declaration of Trust.

Pursuant to the Declaration of Trust, disbursements were made as follows to the Corporate Trustee for the two years ended December 31, 2015 and December 31, 2014:

The Catalogue is estimated to be composed of over 25,000 music titles, of which approximately 1,600 produced royalty income in recent years. Based on the 2015 Listing, the Trust derives its receipts principally from copyrights established prior to 1958 in the Unites States. The receipts fluctuate based on consumer interest in the nostalgia appeal of older songs and the overall popularity of the songs contained in the Catalogue. The Catalogue also generates royalty income in foreign countries in which copyright is claimed.

A number of factors create uncertainties with respect to the Catalogue’s ability to continue to generate royalty income on a continuing, long-term basis for the Trust. These factors include: (i) the effect that foreign and domestic copyright laws and any changes thereto have or will have on renewal rights (e.g., vesting of renewal term rights), (ii) the length of the term of copyright protection under foreign and domestic copyright laws, (iii) reversionary rights that may effect whether EMI is able to retain its rights to the Copyrighted Songs during certain renewal terms (e.g., statutory termination of transfers or “copyright recapture”) and (iv) ongoing disputes regarding the payment and calculation of the Contingent Portion.

The Trust does not own the Catalogue or any copyrights or other intellectual property rights and is not responsible for collecting royalties in connection with the Catalogue. As the current owner and administrator of the Catalogue, EMI is obligated under the Asset Purchase Agreement to use its best efforts to collect all royalties, domestic and foreign, in connection with the Catalogue and to remit a portion of its royalty income to the Trust in accordance with its Contingent Portion payment obligation.

The Trust’s income is dependent, in part, on EMI’s ability to maintain its rights in the Copyrighted Songs through copyright protection. As the copyrights for the Copyrighted Songs expire, less royalty income will be generated, and the size of each payment of the Contingent Portion will be reduced accordingly.

Based on the 2015 Listing, the Top 50 Songs obtained copyright registration under the U.S. Copyright Act of 1909 (the “1909 Act”) between 1922 and 1958. For copyrighted works subject to the 1909 Act, copyright law generally provides for a possible 95 years of copyright protection, subject to certain factors, including the initial registration date of each copyright and compliance with certain statutory provisions including notice and renewal. The Copyright expiration dates for the Top 50 Songs range between 1997 and 2076, as set forth in the 2015 Listing.

The Copyrighted Songs are subject to statutory rights of termination of transfers, which may impact whether EMI is able to retain its ownership of the Copyrighted Songs during their respective terms of copyright protection. For copyrights governed by the 1909 Act, this termination right vests at the end of two different renewal terms, which vary for each Copyrighted Song. As the owner of the Catalogue, EMI (and not the Trust) is responsible for administrating the Catalogue and seeking renewals of the Copyrighted Songs. The Asset Purchase Agreement provides that EMI is obligated to use its best efforts to secure renewals.

NOTE 5. OTHER MATTERS

In October 2014, the Trust made a payment to Wilks, Lukoff & Bracegirdle, LLC (“Wilks”) in the amount of $76,216. The payment was for compensation and reimbursement in respect of fees and expenses of Wilks in connection with the Trust’s Unit Holder meeting held on August 29, 2013, at which the Individual Trustees were elected. In consideration for the payment, Wilks agreed to release the Trust and its affiliates from all claims and demands arising prior to September 30, 2014, including a prior request made by Wilks for compensation and reimbursement in the amount of $200,000.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Trust maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in this report under the Securities Exchange Act of 1934 (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Trust’s management, which is comprised of the Trust Officer of the Corporate Trustee and the Chief Financial Individual providing accounting services to the Trust, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. The Trust’s management has evaluated the effectiveness of the design and operation of the Trust’s disclosure controls and procedures as of December 31, 2015. Based upon that evaluation and subject to the foregoing, the Trust’s management concluded that the design and operation of the Trust’s disclosure controls and procedures provided reasonable assurance that the disclosure controls and procedures are effective to accomplish their objectives.

Management’s Annual Report on Internal Control over Financial Reporting

Management of the Trust is responsible for establishing and maintaining adequate internal control over financial reporting for the Trust as defined in Rule 13a-15(f) under the Exchange Act. The Trust’s internal control over financial reporting is designed to provide reasonable assurance to management regarding the preparation and fair presentation of published financial statements and the reliability of financial reporting.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Management assessed the effectiveness of the Trust’s internal control over financial reporting as of December 31, 2015. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework. Based on management’s assessment, the Trust believes that, as of December 31, 2015, the Trust’s internal control over financial reporting is effective based on those criteria.

This annual report does not include an attestation report of the Trust’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Trust’s registered public accounting firm pursuant to rules of the Securities and Exchange Commission that permit the Trust to provide only management’s report in this annual report on Form 10-K.

Changes in Internal Control Over Financial Reporting

There were no changes in the Trust’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) during the quarter ended December 31, 2015 that materially affected, or are reasonably likely to materially affect, the Trust’s internal control over financial reporting.
