PART I

Item 1.

BUSINESS

The Registrant (“Trust” or “we” or “our” or “GNIOP”) owns interests in fee, both mineral and nonmineral lands, on the Mesabi Iron Range in northeastern Minnesota. The Registrant is a conventional nonvoting trust organized under the laws of the State of Michigan pursuant to a Trust Agreement dated December 7, 1906. Because the Trust properties and offices are all located in Minnesota, the Trust and matters affecting the Trust are under the jurisdiction of the Ramsey County District Court (“Court”) in Saint Paul, Minnesota. Income is primarily derived from royalties on iron ore minerals (taconite) mined by our lessees from these properties and minimum royalties. The Registrant is presently involved primarily with the leasing and care of these properties. There have been no significant changes in these functions since the beginning of the fiscal year.

The terms of the Great Northern Iron Ore Properties Trust Agreement, created December 7, 1906, state that the Trust shall continue for twenty years after the death of the last survivor of eighteen persons named in the Trust Agreement. The last survivor of these eighteen persons died on April 6, 1995. Accordingly, the Trust terminates twenty years from April 6, 1995, that being April 6, 2015.

At the end of the Trust on April 6, 2015, the certificates of beneficial interest (shares) in the Trust will cease to trade on the New York Stock Exchange and thereafter will represent only the right to receive certain distributions payable to the certificate holders of record at the time of the termination of the Trust. Upon termination, the Trust is obligated to distribute ratably to these certificate holders the net monies remaining in the hands of the Trustees (after paying and providing for all expenses and obligations of the Trust), plus the balance in the Principal Charges account (this account is explained in the Trust’s Annual Report sent to all certificate holders every year). All other Trust property (most notably the Trust’s mineral properties and the active leases) must be conveyed and transferred to the reversioner (currently Glacier Park Company, a wholly owned subsidiary of ConocoPhillips Company) under the terms of the Trust Agreement.

The Trust has previously provided information in its various Securities and Exchange Commission filings, including its Annual Report, about the final distribution payable to the certificate holders upon the Trust’s termination. The exact final distribution, though not determinable at this time, will generally consist of the sum of the Trust’s net monies (essentially, total assets less liabilities and properties) and the balance in the Principal Charges account, less any and all expenses and obligations of the Trust upon termination. To offer a hypothetical example, without factoring in any expenses and obligations of the Trust upon its termination, and using the financial statement values as of December 31, 2012, the net monies were approximately $7,719,000 and the

Item 1.

BUSINESS – continued

Principal Charges account balance was approximately $4,871,000, resulting in a final distribution payable of approximately $12,590,000, or about $8.39 per share. After payment of this final distribution, the certificates of beneficial interest (shares) would be cancelled and have no further value. It is important to note, however, that the actual net monies on hand and the Principal Charges account balance will most likely fluctuate during the ensuing years and will not be “final” until after the termination and wind-down of the Trust. The Trust offers this example to further inform investors about the conceptual nature of the final distribution and does not imply or guarantee a specific known final distribution amount.

The raw materials essential to the business of the Registrant are the minerals contained in properties owned and leased by the Registrant. Because we lease our properties to mining interests that control the amount of ore production, we do not have direct control over the tonnage mined from our properties; we are primarily involved with administering the leases on the properties. Since operating companies insist on freedom to move from property to property as mining requirements dictate, such changes in production cannot be precisely reduced to financial forecasts.

Although the Registrant owns in excess of 67,000 acres in varied fee (surface and/or mineral) and ownership percentage interests in northeastern Minnesota, our mineral interests on the Mesabi Iron Range formation represent 12,033 acres, including approximately 7,443 acres that are wholly owned, 1,080 acres in which the Registrant is a tenant in common with a 91% interest, 3,350 acres in tenancy in common with a 50% interest and 160 acres in tenancy in common with other fractional interests. Of said mineral interest total, 9,895 acres are under lease and 2,138 acres are unleased.

None of the Registrant’s leases provide for any right of renewal by the lessees upon expiration, even though unmined minerals might remain. Any extension of any such terminating lease would have to be negotiated in the same manner as unleased properties.

The Registrant cannot estimate at this time any tonnage for nonmagnetic taconite because of lack of drilling, testing and any established large-scale commercial treatment method for Mesabi Iron Range nonmagnetic taconite. To give a better perspective on magnetic taconite, our engineers estimate that the proven and probable ore reserves of magnetic taconite under lease as of December 31, 2012, were equivalent to approximately 358,639,000 tons of pellets. These ore reserves are developed from exploration drilling (diamond drilling) analyses performed by our lessees (steel and mining companies), with our interaction and assistance, though they have never been audited by any external party as this is not a customary practice. Although the ore reserves generally are adjusted downward each year for taconite pellet shipments, they also may increase due to new leases entered into and/or amendments to existing leases

Item 1.

BUSINESS – continued

that may provide for the development of additional reserves. In addition, reserve adjustments (positive or negative) are made from time to time when additional diamond drilling results in adjustments to the estimates (see table of current leases within this “Item 1. Business” section for additional reserve information).

Present taconite leases provide for minimum royalties aggregating approximately $6,152,000 for the year 2013 even if no taconite is mined. This entire amount is attributable to long-term taconite leases.

All leases granted by the Registrant, except some covering remnants of natural ore, have provisions for escalation of royalty rates. Most of the taconite royalty rates are escalated on the basis of the price of pellets, the iron content, the Producers Price Index (“PPI”) (All Commodities), the PPI (Iron and Steel subgroup) or certain combinations of the above.

There are other landowners on the Mesabi Iron Range, including mining companies and numerous other private fee owners. Accordingly, firm data on competitive conditions in the iron ore industry is not available. Iron ore is also available from a number of other sources. However, the generally close proximity of our lands to the mining facilities tends to provide a competitive advantage to the Trust. In addition, other typical competitive factors include royalty rates, quality and geological characteristics of the ore bodies available, production guarantees granted to the fee owners, minimum royalty provisions and other matters. The Registrant’s non-taconite shipments have presently ceased as a source of income. The mining of taconite by lessees is the most important part of our present business. Future development depends, to a large part, on the demand for taconite from our properties by the steel and mining companies.

The Registrant’s royalty income is dependent on the number of tons of taconite shipped from its properties by the lessees, royalty rates, minimum royalties collected and absorption of minimum royalties collected. Following is a summary of shipments by lessee (operating facility) for the years 2012, 2011 and 2010:

	Pellet Tons Shipped
	2012		2011		2010

U.S. Steel Corporation – Minntac		3,237,598		4,051,571		3,408,528
Hibbing Taconite Company		3,211,256		3,487,176		3,144,896
U.S. Steel Corporation – Keetac		911,602		381,576		747,610
		7,360,456		7,920,323		7,301,034

As previously reported, Section 646 of the Tax Reform Act of 1986, as amended, provided a special elective provision under which the Trust was allowed to convert from taxation as a corporation to that of a grantor trust. Pursuant to an Order of the

Item 1.

BUSINESS – continued

Ramsey County District Court, the Trustees filed the Section 646 election with the Internal Revenue Service (“IRS”) on December 30, 1988. As of January 1, 1989, the Trust was no longer subject to federal and Minnesota corporate income taxes. For years 1989 and thereafter, certificate holders are taxed on their allocable share of the Trust’s income whether or not the income is distributed. For certificate holder tax purposes, the Trust’s income is determined on an annual basis, one-fourth then being allocated to each quarterly record date.

The Trustees provided annual income tax information in January 2013 to registered certificate holders of record with holdings on any of the four quarterly record dates during 2012. This information included the following:

Substitute Form 1099-MISC – This form reported the registered certificate holder’s 2012 allocable share of income from the Trust, distributions declared and any taxes withheld. (Foreign registered certificate holders received a Form 1042-S.)

Trust Supplemental Statement – This statement reported the number of units (shares) held by the registered certificate holder on any of the four quarterly record dates in 2012.

Tax Return Guide – This guide instructed the certificate holders as to the preparation of their income tax returns with respect to income allocated from the Trust and various deductions allowable.

At December 31, 2012, the Registrant employed ten persons. We have been engaged in only one line of business, namely the leasing and maintenance of our mineral properties. Our business is not seasonal, but income primarily depends upon production by the steel and mining companies that lease our properties. We have no operations in foreign countries. Our customers’ (or lessees’) taconite facilities are all located in northeastern Minnesota, though the ownership interests and/or corporate headquarters are elsewhere, as explained in the footnotes to the table below.

The Registrant maintains a Web site, which can be found at www.gniop.com. Information about the Registrant posted on the Web site includes: General Trust information (including information about the termination of the Trust), Securities and Exchange Commission filings (Forms 10-K, Forms 10-Q, Forms 8-K), Annual Reports, Tax Return Guides, Quarterly Distribution Releases, Quarterly Earnings Releases, Court Hearings, Audit Committee Charter, Code of Ethics, Contact and other information. We will, upon request, be pleased to furnish to any certificate holder or investor, free of charge, a paper copy of any of the above documents for any recent year.

Item 1A.

RISK FACTORS

Certain expectations and projections regarding future performance of the Registrant referenced in this report are forward-looking statements. These expectations and projections are based on currently available industry and financial data and may be subject to certain events and uncertainties beyond our control. We caution readers that in addition to factors described elsewhere in this report, the following factors and comments, among others, could cause our operations and financial results to differ materially from the expectations and projections contained in the forward-looking statements.

The Registrant is dependent on a limited number of customers.

Our lessees (customers) primarily include Minntac and Keetac, owned and operated by U.S. Steel Corporation; Hibtac, owned by ArcelorMittal, Cliffs Natural Resources Inc. and U.S. Steel Corporation, and operated by Cliffs Mining Company; and ESM, owned by Essar Steel Holdings Ltd., a subsidiary of Essar Global Ltd., with a new taconite mining and steelmaking facility to be constructed by ESM over the next few years. Because our revenues are primarily dependent upon a limited number of customers, any significant adverse event at any of our primary lessees, or the loss of any of our primary lessees, could materially adversely affect our future financial results.

The Registrant is subject to market forces beyond its control.

A decline in market demand for steel, and correspondingly taconite, could adversely affect our financial results. However, other related and sometimes compensating factors include our lessees’ operating levels, minimum royalties, ore body quality, metallurgical and geological characteristics, and location of our lands. Also sometimes affecting taconite production from our lands are extreme weather conditions and labor contracts at the mines. Though we are not a party to the labor contracts, all pertinent labor contracts affecting production from our lands run through August 31, 2015. Additionally, over the past few years, the domestic steel and taconite industries have also been influenced by the global markets. As a result, the future demand for domestic steel and taconite, which is now part of the global markets, is uncertain. While any cut in production by any of our lessees can adversely affect the Trust, continued receipt of minimum royalties do mitigate this effect, in part.

The Registrant’s royalty rates are generally tied to producer price indices.

Royalty rates can fluctuate due to the escalation and de-escalation of producer price indices as a result of provisions present in many of our leases. To the extent these indices decline (All Commodities or the Iron and Steel subgroup), royalty rates, and correspondingly royalty income, could be adversely affected. Conversely, higher producer price indices may increase royalty rates and royalty income.

Item 1A.

RISK FACTORS – continued

The loss of grantor trust status would have adverse tax consequences.

Compliance with Section 646 of the Internal Revenue Code is integral to the level of distributions paid to the certificate holders. Should it be determined that we have violated the requirements of Section 646, the Trust would be taxed as a corporation versus a grantor trust. This would mean our income would be taxable upon our receipt and again upon receipt by the certificate holders. It is the Trustees’ opinion that the Trust has remained in compliance with the provisions of Section 646 since its election in 1988.

Item 1B.

UNRESOLVED STAFF COMMENTS

None.

Item 2.

PROPERTIES

The Registrant owns interests in fee, both mineral and nonmineral lands, on the Mesabi Iron Range in northeastern Minnesota, many of which are leased to the steel and mining companies that mine the mineral lands for taconite ore. A list of the leased properties is shown in table format in “Item 1. Business” above. The leases provide the lessees exclusive mining rights during the term of such leases. Taconite deposits are substantial, and our ore reserves are deemed proven and probable. The properties have a reversionary interest as explained in “Item 1. Business” above.

Item 3.

LEGAL PROCEEDINGS

In proceedings commenced in 1972, the Minnesota Supreme Court determined that while, by the terms of the Trust, the Trustees are given discretionary powers to convert Trust assets to cash and to distribute the proceeds to certificate holders, they are limited in their exercise of those powers by the legal duty imposed by well-established law of trusts to serve the interests of both the term beneficiaries and the reversionary beneficiary with impartiality. Thus, the Trustees have no duty to exercise the powers of sale and distribution unless required to do so to serve both term and reversionary interests; and, if the need arises, the Trustees may petition the Ramsey County District Court, Saint Paul, Minnesota, for further instructions defining what is required in a particular case to balance the interests of certificate holders and reversioner. Also, the Minnesota Supreme Court, in effect, held that the Trust is a conventional trust, rather than a business trust, and must operate within the framework of well-established trust law.

Item 3.

LEGAL PROCEEDINGS – continued

Section 646 of the Tax Reform Act of 1986, as amended, provided a special elective provision under which the Trust was allowed to convert from taxation as a corporation to that of a grantor trust. Pursuant to an Order of the Ramsey County District Court, the Trustees filed the Section 646 election with the Internal Revenue Service on December 30, 1988. As of January 1, 1989, the Trust was no longer subject to federal and Minnesota corporate income taxes. For years 1989 and thereafter, certificate holders are taxed on their allocable share of the Trust’s income whether or not the income is distributed. For certificate holder tax purposes, the Trust’s income is determined on an annual basis, one-fourth then being allocated to each quarterly record date.

By a letter dated April 27, 2012, certificate holders of record as of December 30, 2011 (the last business day of the year), and the reversioner were notified of a hearing on May 22, 2012, in Ramsey County District Court, Saint Paul, Minnesota, for the purpose of settling and allowing the Trust accounts for the year 2011, and also for the purpose of considering requested fee increases in the compensation of the Trustees. By Court Order signed and dated May 22, 2012, the 2011 accounts were settled and allowed in all respects. In addition, the Court granted the requested fee increases of $20,000 per year to the President of the Trustees’ base salary and $20,000 per year to the potential bonus of the President, an increase of $10,000 per year to each of the other Trustees, and an additional amount of $5,000 per year to the Trustee serving in the role of Audit Committee Chair, all effective January 1, 2012. By previous Orders, the Court settled and allowed the accounts of the Trustees for preceding years of the Trust.

Information Regarding Board of Trustees and Corporate Governance

As provided in the Trust Agreement, should a vacancy exist on the Board of Trustees, the remaining Trustees meet and jointly select another Trustee to fill the position. In the unlikely event there are no remaining Trustees, the Trust Agreement provides additional guidance to re-create a Board. Once appointed to the Board, the Trustees seek Court approval and confirmation from the Ramsey County District Court in Saint Paul, Minnesota. Accordingly, certificate holders of the Trust’s certificates of beneficial interest have no authority to elect Trustees or to nominate persons to serve on the Board. The Trust has no express diversity policy; however, the Trustees seek to maintain among the Board members experience in various disciplines relevant to the Trust’s business. The leadership structure of the Board of Trustees is established by the Trust Agreement, which combines the positions of the President of the Trustees and the Chief Executive Officer of the Trust. Mr. Micallef currently holds both of these positions. As Audit Committee Chairman, Mr. Stein currently serves as the Trust’s lead independent member and presides at all non-management executive sessions.

The Board of Trustees is responsible for oversight of the risks inherent in the Trust’s business. The Board regularly reviews information regarding the Trust’s liquidity and operations, as well as the risks associated with each. In addition, the Board receives regular reports from management on areas of material risk to the Trust, if any, including operational, financial, legal, regulatory, strategic and reputational risks. The Audit Committee oversees the Trust’s internal controls and financial accounts, and regularly assesses financial and accounting processes and risks.

In 2002, the Board of Trustees adopted a Code of Ethics that applies to all Trustees and employees. The Trustees intend to maintain the highest standards of ethical business practices and compliance with all laws and regulations applicable to the Trust’s business. The Code of Ethics is available within the Corporate Governance Disclosures section on the Trust’s Web site, which can be found at www.gniop.com.

Compensation Discussion and Analysis

The Trust has only two executive officers, the President of the Trustees and Chief Executive Officer (“CEO”) and the Vice President & Secretary and Chief Financial Officer (“CFO”), as shown above in the Summary Compensation Table. No other Trust personnel receive compensation in excess of these named executives. The compensation for the Trust’s other directors (Trustees other than the CEO) is discussed and shown below under a separate table.

The compensation of the Trustees and CEO is established by the Trust Agreement (as modified by Court Orders). That is, the CEO does not participate in setting his own compensation. In addition, the Board of Trustees, as a whole, establishes and approves all compensation for all employees of the Trust (including that of the CFO) based on market data obtained from time to time, as deemed necessary.

Compensation Committee Report & Interlocks and Insider Participation

The Board of Trustees, as a whole, has reviewed and discussed this Compensation Discussion and Analysis (“CD&A”) with management and, based on such review and discussion, has recommended that the CD&A be included in the Registrant’s annual report. The Board of Trustees has not designated a separate compensation committee, and the Trustees take all actions with respect to risk oversight and compensation themselves due to their trustee fiduciary obligations pursuant to the Trust Agreement.

This report is respectfully submitted by Joseph S. Micallef, Roger W. Staehle, Robert A. Stein and James E. Swearingen, collectively, as the Board of Trustees of Great Northern Iron Ore Properties.

Item 11.

EXECUTIVE COMPENSATION – continued

President of the Trustees/Chief Executive Officer (CEO) Compensation

The Trust Agreement (as modified by Court Orders, the last being effective January 1, 2012) provides for current annual compensation (salary) to the CEO of $200,000. The Trust Agreement (as modified by Court Orders, the last being effective January 1, 2012) also provides for current additional compensation (bonus) to the CEO equal to one percent (1%) of the excess of annual gross income of the Trust over $5,000,000, with a maximum bonus of $100,000.

The original 1906 Trust Agreement provided for compensation to the CEO of $25,000, plus additional compensation (bonus) equal to one percent (1%) of the excess of annual gross income of the Trust over $5,000,000, with a maximum bonus of $25,000. Between 1906 and 1982, the compensation of the CEO had never been adjusted. Because of the time-consuming legal proceedings that occurred in the 1970s and 1980s, and the fact that there had not been an increase in compensation since the inception of the Trust, the Trustees petitioned the Court for an increase in compensation to reflect, in part, their increased time commitments and inflation over the years.

By Court Order effective January 1, 1983, the CEO’s compensation was adjusted to $40,000, and the maximum bonus was adjusted to $35,000. Thereafter, because of increased duties under today’s regulatory environment and further inflation, the Trustees have, from time to time, petitioned the Court for additional compensation increases, essentially based on the increases in the Consumer Price Index since 1983. This petition process includes notification to all certificate holders of record and the reversioner, followed by a formal Court hearing and opportunity by certificate holders and reversioner to comment. The Court, taking into consideration any and all testimony and other materials filed, has approved of increases to the CEO’s compensation a total of eight different times since 1906, the last being effective January 1, 2012.

Because the compensation of the CEO is set forth by the Trust Agreement (as modified by Court Orders), there are no stock awards, option awards, non-equity incentive plan compensation, change in pension value and nonqualified deferred compensation earnings or all other compensation. Accordingly, such columns in the table and the corresponding supplemental tables have been omitted.

Item 11.

EXECUTIVE COMPENSATION – continued

Vice President & Secretary/Chief Financial Officer (CFO) Compensation

The Board of Trustees, as a whole, determines the compensation of all employees of the Trust, including that of the CFO. The objective for determining the compensation of the CFO is to provide a competitive salary based on market data obtained from time to time, as deemed necessary, representative of other chief financial officers’ responsibilities and pay scales within other similar-sized companies. To determine reasonable and competitive salary ranges for all employees of the Trust, including the CFO, the Trustees retained independent market research firms to obtain market data reflective of each specific position. Studies were performed and obtained in 1990 and updated again in 2001. With respect to the CFO’s base salary, the market salary averages and ranges obtained in the 2001 study reflected compensation paid to various chief financial officers in 47 different, similar-sized organizations (representing the lower twenty-five percent quartile of all companies sampled).

Since 2001, the Trustees have extrapolated the historical salary percentage increase that occurred between 1990 and 2001 forward to current year dollars or, if greater, adjusted the salary ranges based on the change in the Consumer Price Index since 2001. The Trustees intend to target the CFO’s base salary to fall within the range of this 2001 study, as extrapolated to current year dollars. The CFO’s base salary for 2012 falls within that range.

In addition to the CFO’s base salary, the Summary Compensation Table includes $1,900, $3,200 and $5,900 under the column heading “Salary” for nonqualified deferred compensation plan contributions accrued by the Trust for the benefit of the CFO for the years 2012, 2011 and 2010, respectively (as discussed and shown below under a separate table).

The CFO’s bonus compensation was established in 2001 to reward the CFO for any productive year by the Trust that effectively results in gross revenues in excess of $5,000,000, the same threshold used for the bonus calculation of the CEO. The CFO’s bonus compensation is equal to ten percent (10%) of the CEO’s bonus compensation, resulting in a current maximum annual bonus of $10,000.

The increase in the actuarial present value of accumulated benefits under the column heading “Pension Values” for the CFO within the Trust’s defined benefit pension plan (as discussed and shown below under a separate table) amounted to $193,938, $114,476 and $141,044 for the years 2012, 2011 and 2010, respectively. The CFO participates in the pension plan, along with all other employees, on a nondiscriminatory basis.

Item 11.

EXECUTIVE COMPENSATION – continued

In addition to the CFO’s compensation attributed to the increase in the actuarial present value of accumulated benefits as stated above, the column heading “Pension Values” also includes $2,839, $4,518 and $4,357 of above-market returns pertaining to nonqualified deferred compensation earnings accrued by the Trust for the benefit of the CFO for the years 2012, 2011 and 2010, respectively, under the nonqualified deferred compensation plan (as discussed and shown below under a separate table).

The CFO does not receive any stock awards, option awards or non-equity incentive plan compensation. Accordingly, such columns in the table and the corresponding supplemental tables have been omitted. In addition, the CFO did not receive any other compensation that would require disclosure under the column heading “All Other Compensation.”

Defined Benefit Pension Plan

$1,059,137

$—

Only employees of the Trust (not Trustees) are eligible to participate in the Trust’s pension plan and, as such, post-employment compensation disclosure is not applicable for the CEO or the other Trustees. The CFO, as an employee of the Trust, does participate in the Trust’s defined benefit pension plan on a nondiscriminatory basis with the other employees of the Trust.

The Number of Years Credited Service reflects the years of credited service currently vested as of December 31, 2012. The normal retirement benefit is a straight life annuity as of the end of the Trust and is based on the highest sixty (60) consecutive months average salary (annualized), the years of credited service and three percent (3%) per year of credited service, as defined in the pension plan.

Item 11.

EXECUTIVE COMPENSATION – continued

The pension plan also provides for a $500/month supplemental bridge payment (a nondiscriminatory benefit) that begins as of the end of the Trust (due to an involuntary early retirement resulting from Trust termination) and continues until the earlier of the participant’s death or attainment of age 65. The early retirement age, as defined in the pension plan, is the earliest date that the participant could elect early retirement based on the participant’s years of credited service and the participant’s age, the sum of which must equal or exceed 62. The CFO is currently eligible to elect an early retirement benefit. The early retirement benefit is calculated similar to the normal retirement benefit, except the percentage used for years of credited service equals two and one-quarter percent (2 1/4%), and the benefit is reduced by 1/15 for each of the first five years preceding the normal retirement age of 65 and by 1/30 for each year before that until the early retirement age is reached, and the $500/month supplemental bridge payment is not applicable. However, if an employee is eligible for early retirement as of the end of the Trust, the employee’s benefit will be unreduced, similar to the calculation of the normal retirement benefit. Actuarial equivalent annuity options are also available to all participants in the pension plan in lieu of a straight life annuity.

Thomas A. Janochoski (CFO)	$—	$1,900	$5,500	$—	$101,900

The Trustees established a nonqualified deferred compensation plan for the CFO in 2001. The Registrant’s contributions to the deferred compensation plan for the CFO represent the difference between (i) what the CFO is limited to contributing to his account within a 401(k) Supplemental Retirement Plan (a plan provided on a nondiscriminatory basis to all employees, without company match or profit sharing) because of his “highly compensated employee” status as defined by IRS regulations, and (ii) the maximum amount other employees, subject to IRS thresholds, are permitted to contribute to their accounts.

Aggregate Earnings in the Last Fiscal Year represent interest earned on the Aggregate Balance at Last Fiscal Year-End within the deferred compensation plan. The interest percentage used to determine interest earned is the greater of five percent (5%) or the actual one-year current return achieved within the Trust’s defined benefit pension plan. The Aggregate Balance at Last Fiscal Year-End is distributable at the earliest of (i) the CFO’s termination of employment, (ii) the termination of the Trust (April 6, 2015), (iii) the CFO’s termination of employment due to disability, or (iv) the CFO’s death.

Item 11.

EXECUTIVE COMPENSATION – continued

Of the total $1,900 in Registrant Contributions in the Last Fiscal Year and total $5,500 in Aggregate Earnings in the Last Fiscal Year listed in the table above, $1,900 (deferred compensation) and $2,839 (above-market earnings), respectively, are included in the Summary Compensation Table under the respective column headings “Salary” and “Pension Values” for the year 2012. In addition, of the total $101,900 Aggregate Balance at Last Fiscal Year-End listed in the table above, $3,200 and $5,900 (deferred compensation) are included in the Summary Compensation Table under the column heading “Salary” for the years 2011 and 2010, respectively; and $4,518 and $4,357 (above-market earnings) are included in the Summary Compensation Table under the column heading “Pension Values” for the years 2011 and 2010, respectively.

The Trust Agreement (as modified by Court Orders, the last being effective January 1, 2012) provides for current annual compensation (fees) to each Trustee (other than the CEO) of $80,000. In addition and also pursuant to Court Order, the Trustee serving in the role of Audit Committee Chair receives an additional amount of $5,000 per year.

The original 1906 Trust Agreement provided for compensation of $10,000 to each of the other Trustees (other than the CEO). Between 1906 and 1982, the compensation of the Trustees (other than the CEO) had never been adjusted. Because of the time-consuming legal proceedings that occurred in the 1970s and 1980s, and the fact that there had not been an increase in compensation since the inception of the Trust, the Trustees petitioned the Court for an increase in compensation to reflect, in part, their increased time commitments and inflation over the years.

EXECUTIVE COMPENSATION – continued

By Court Order effective January 1, 1983, the Trustees’ (other than the CEO) compensation was adjusted to $20,000. Thereafter, because of increased duties under today’s regulatory environment and further inflation, the Trustees have, from time to time, petitioned the Court for additional compensation increases, essentially based on the increases in the Consumer Price Index since 1983. This petition process includes notification to all certificate holders of record and the reversioner, followed by a formal Court hearing and opportunity by certificate holders and reversioner to comment. The Court, taking into consideration any and all testimony and other materials filed, has approved of increases to the Trustees (other than the CEO) a total of seven different times since 1906, the last being effective January 1, 2012.

Because the compensation of the Trustees (other than the CEO) is set forth by the Trust Agreement (as modified by Court Orders), there are no stock awards, option awards, non-equity incentive plan compensation, change in pension value and nonqualified deferred compensation earnings or all other compensation. Accordingly, such columns in the table and the corresponding supplemental tables have been omitted.
