DOCUMENTS INCORPORATED BY REFERENCE

Portions of the Annual Report to Certificate Holders for the year ended December 31, 2013, attached hereto as Exhibit 13, are incorporated by reference into Part II.

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.
	Upon the termination date 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 Trust termination and after the wind-down process is completed, 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 incurred through the Trust’s termination and wind-down process), 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 of which are subject to the final accounting and approval of the Ramsey County District Court. 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), without further payment or remuneration to the certificate holders, under the terms of the Trust Agreement. The wind-down process of the Trust is anticipated to extend into the calendar year following its termination date in order to complete the various year-end audits, court and regulatory filings, tax returns, conveyances of non-cash properties to the reversioner, etc., relative thereto. Subject to the guidance and approval of the Ramsey County District Court and assuming the wind-down process with the reversioner proceeds efficiently and that no other complications arise during this time period, we anticipate the wind-down process, final distribution and dissolution of the Trust will be completed by the end of 2016.

1

Item 1.	BUSINESS – continued
	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 and after the wind-down process is completed. 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 less properties) and the balance in the Principal Charges account, less any and all expenses and obligations incurred through the Trust’s termination and wind-down process. To offer a hypothetical example, without factoring in any expenses and obligations incurred through the Trust’s termination and wind-down process, and using the financial statement values as of December 31, 2013, the net monies were approximately $9,790,000 and the Principal Charges account balance was approximately $4,789,000, resulting in a final distribution payable of approximately $14,579,000, or about $9.72 per share. Upon the termination of the Trust, the certificates of beneficial interest (shares) would be cancelled and have no further value with the exception of the final distribution. 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 process of the Trust is completed. 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 the mining companies insist on the flexibility to move from property to property (though not necessarily to another Trust property) as mining requirements dictate, such changes in production cannot be predicted or 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.

2

Item 1.	BUSINESS – continued
	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, 2013, were equivalent to approximately 352,183,000 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 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. Refer to the table of current leases within this “Item 1. Business” section for additional reserve information.
	Present taconite leases provide for minimum royalties aggregating approximately $6,107,000 for the year 2014 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.

Item 1.	BUSINESS – continued
	Following is a summary of shipments by lessee (operating facility) for the years 2013, 2012 and 2011:
			Pellet Tons Shipped
			2013	2012	2011
	Hibbing Taconite Company		2,954,715	3,211,256	3,487,176
	U.S. Steel Corporation – Minntac		2,922,771	3,237,598	4,051,571

			6,456,047	7,360,456	7,920,323
	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 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 2014 to registered certificate holders of record with holdings on any of the four quarterly record dates during 2013. This information included the following:
	•	Substitute Form 1099-MISC – This form reported the registered certificate holder’s 2013 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 2013.
	•	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, 2013, 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.

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., which includes a new taconite mining plant (and future steelmaking facility) currently being constructed by ESM with a projected startup date in late 2014 or early 2015. 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 (the “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.

7

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.
	The Trust terminates April 6, 2015.
	As previously reported, the termination date of the Trust is April 6, 2015. Accordingly, acknowledging the downward movement of the share price of certificates of beneficial interest in early 2014, we remind certificate holders that there will be remaining only four regular quarterly distributions declared in the year 2014 and one regular quarterly distribution declared in the year 2015. While there will be some income allocated to the second quarter of 2015 (representing six days of business), it is expected that this amount will be nominal and will likely be included with the final distribution to certificate holders, which final distribution will occur upon the completion of the wind-down process of the Trust and upon approval of the Trust’s final accounting by the Judge of the Ramsey County District Court. As described earlier in this report, upon termination of the Trust on April 6, 2015, the certificates of beneficial interest (shares) will be cancelled and have no further value other than the final distribution.
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.

8

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.
	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 1, 2013, certificate holders of record as of December 31, 2012, and the reversioner were notified of a hearing on May 8, 2013, in Ramsey County District Court, Saint Paul, Minnesota, for the purpose of settling and allowing the Trust accounts for the year 2012. By Court Order signed and dated May 8, 2013, the 2012 accounts were settled and allowed in all respects. 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.

17

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 2013 falls within that range.
	In addition to the CFO’s base salary, the Summary Compensation Table includes $0, $1,900 and $3,200 under the column heading “Salary” for nonqualified deferred compensation plan contributions accrued by the Trust for the benefit of the CFO for the years 2013, 2012 and 2011, 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 $27,637, $193,938 and $114,476 for the years 2013, 2012 and 2011, respectively. The CFO participates in the pension plan, along with all other employees, on a nondiscriminatory basis.

18

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 $2,536, $2,839 and $4,518 of above-market returns pertaining to nonqualified deferred compensation earnings accrued by the Trust for the benefit of the CFO for the years 2013, 2012 and 2011, 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.”
	Post-Employment Compensation

Name	Plan Name	Number of Years Credited Service	Present Value of Accumulated Benefit	Payments During Last Fiscal Year
Thomas A. Janochoski (CFO)	Defined Benefit Pension Plan	24	$1,086,774	$—

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, 2013. 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.

19

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.

Nonqualified Deferred Compensation Table
Name	Executive Contributions in the Last Fiscal Year	Registrant Contributions in the Last Fiscal Year	Aggregate Earnings in the Last Fiscal Year	Aggregate Withdrawals/ Distributions	Aggregate Balance at Last Fiscal Year-End
Thomas A. Janochoski (CFO)	$—	$0	$6,400	$—	$108,300

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.

20

Item 11.	EXECUTIVE COMPENSATION – continued
	Of the total $0 in Registrant Contributions in the Last Fiscal Year and total $6,400 in Aggregate Earnings in the Last Fiscal Year listed in the table above, $0 (deferred compensation) and $2,536 (above-market earnings), respectively, are included in the Summary Compensation Table under the respective column headings “Salary” and “Pension Values” for the year 2013. In addition, of the total $108,300 Aggregate Balance at Last Fiscal Year-End listed in the table above, $1,900 and $3,200 (deferred compensation) are included in the Summary Compensation Table under the column heading “Salary” for the years 2012 and 2011, respectively; and $2,839 and $4,518 (above-market earnings) are included in the Summary Compensation Table under the column heading “Pension Values” for the years 2012 and 2011, respectively.
	Compensation of Directors/Trustees (Other Than the CEO)

Directors Compensation Table
Name	Current Fiscal Year Fees Earned or Paid in Cash
Roger W. Staehle, Trustee	$	80,000
Robert A. Stein, Trustee and Audit Committee Chair		85,000
James E. Swearingen, Trustee		80,000

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.

21

Item 11.	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.
Item 12.	SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS
	(a)	The only authorized securities of the Registrant are Trustees’ Certificates of Beneficial Interest. These securities are traded on the New York Stock Exchange under the ticker symbol “GNI” (CUSIP No. 391064102). The holders of these securities do not have voting rights. The Trust is not aware of any entities holding more than 5% of the Certificates of Beneficial Interest outstanding, of record and/or beneficially, as of December 31, 2013.
	(b)	There were no Certificates of Beneficial Interest of Great Northern Iron Ore Properties owned or pledged by the Trustees or officers of the Trust as of December 31, 2013.
Item 13.	CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE
	There are no certain relationships or related transactions requiring disclosure under this section. Director independence is set forth in “Item 10. Directors, Executive Officers and Corporate Governance” of this report.

Item 14.	PRINCIPAL ACCOUNTING FEES AND SERVICES
	All audit and non-audit services (printing and reproduction services) were preapproved by the Audit Committee. Fees paid in 2013 for the annual audit services were $90,400, for audit-related services were $1,600, for tax services were $0 and for all other services were $3,000. Fees paid in 2012 for the annual audit services were $86,700, for audit-related services were $1,600, for tax services were $0 and for all other services were $3,000.

Trustees’ & Management’s Discussion and Analysis of Financial Condition
and Results of Operations

Overview: Great Northern Iron Ore Properties (the “Trust”) is a conventional nonvoting trust organized under the laws of the State of Michigan pursuant to a Trust Agreement dated December 7, 1906. The Trust owns interests in fee, both mineral and nonmineral lands, on the Mesabi Iron Range in northeastern Minnesota. Many of these properties are leased to steel and mining companies that mine the mineral lands for taconite iron ore. The Trust has no subsidiaries. With the properties and offices all located in Minnesota, the Trust and matters affecting the Trust are under the jurisdiction of the Ramsey County District Court (the “Court”) in Saint Paul, Minnesota.

The Trust maintains a Web site, which can be found at www.gniop.com. Information about the Trust 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.

During 2013, the major source of income to the Trust was royalty income derived from taconite production and minimum royalties. Certain leases provide the steel and mining companies the ability to offset royalties, over the minimum royalty requirements, due on future taconite production, if any and when mined, against unabsorbed minimum royalties paid in prior periods. A “Summary of Shipments” is tabulated on the last page of this report.

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.

Upon the termination date 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 Trust termination and after the wind-down process is completed, 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 incurred through the Trust’s termination and wind-down process), plus the balance in the Principal Charges account (see Note 6 to the Financial Statements), all of which are subject to the final accounting and approval of the Ramsey County District Court. 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), without further payment or remuneration to the certificate holders, under the terms of the Trust Agreement. The wind-down process of the Trust is anticipated to extend into the calendar year following its termination date in order to complete the various year-end audits, court and regulatory

3

filings, tax returns, conveyances of non-cash properties to the reversioner, etc., relative thereto. Subject to the guidance and approval of the Ramsey County District Court and assuming the wind-down process with the reversioner proceeds efficiently and that no other complications arise during this time period, we anticipate the wind-down process, final distribution and dissolution of the Trust will be completed by the end of 2016.

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 less properties) and the balance in the Principal Charges account, less any and all expenses and obligations incurred through the Trust’s termination and wind-down process. To offer a hypothetical example, without factoring in any expenses and obligations incurred through the Trust’s termination and wind-down process, and using the financial statement values as of December 31, 2013, the net monies were approximately $9,790,000 and the Principal Charges account balance was approximately $4,789,000, resulting in a final distribution payable of approximately $14,579,000, or about $9.72 per share. Upon the termination of the Trust, the certificates of beneficial interest (shares) would be cancelled and have no further value with the exception of the final distribution. 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 process of the Trust is completed. 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 Trust is primarily involved with the leasing and care of its properties. The management of the Trust is vested in the Trustees. The Trustees have no duty to sell property unless required to do so to serve both the term beneficiaries and the reversionary beneficiary impartially; and, if the need arises, the Trustees may petition the Court for further instructions defining what is required in a particular case to balance the interests of the certificate holders and reversioner. The major source of income to the Trust is earned royalties derived from taconite production from the Trust’s properties by the Trust’s lessees (customers) and minimum royalties, pursuant to mineral leases. “Earned royalties” are based on the taconite tonnage mined (also referred to as produced or shipped) from the Trust’s lands applied to a royalty rate as defined in the various specific and confidential operating agreements (also referred to as leases) with the Trust’s lessees. Certain leases have “minimum royalty” provisions that require the lessee to remit to the Trust current year rental or minimum royalty income for holding the leasehold interest. The leases are generally very long-term in nature and, while they periodically are amended at the request of a lessee, the Trust is bound by the lease provisions throughout the term of the lease.

Pursuant to a Court Order in 1988, the Trustees filed an election under Section 646 of the Tax Reform Act of 1986, as amended, of the Internal Revenue Code with the Internal Revenue Service that allowed the Trust to be taxed as a grantor trust versus a corporation. Accordingly, certificate holders (shareholders) are taxed on their allocable share of the Trust’s income whether or not the income is distributed.

The Trustees provided annual income tax information in January 2014 to registered certificate holders of record with holdings on any of the four quarterly record dates during 2013. This information included the following:

• Substitute Form 1099-MISC — This form reported the registered certificate holder’s 2013 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 2013.

• 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.

Shares of beneficial interest in the Trust are traded on the New York Stock Exchange under the ticker symbol “GNI” (CUSIP No. 391064102). There were 811 registered certificate holder of record accounts on December 31, 2013. The high and low sales prices for the quarterly periods commencing January 1, 2012, through December 31, 2013, inclusive, were as follows:

	2013				2012
Quarter	High		Low		High		Low
First	$	82.00	$	66.20	$	125.98	$	92.35
Second		74.01		61.50		100.85		58.90
Third		76.74		67.00		89.99		61.11
Fourth		75.49		67.41		82.50		65.24

Results of Operations: Royalties for 2013 were less than those of 2012 by approximately $5.2 million primarily due to decreased taconite mining on our lands, which accounted for approximately $2.7 million of this total change, and a lower overall average earned royalty rate caused by lower producer price indices that impact our royalty rates, which accounted for approximately $2.7 million of this total change, offset in part by increased tailings revenues, which accounted for approximately $0.2 million of this total change. Expenses for 2013 were greater than those of 2012 by approximately $0.1 million primarily due to higher pension expense pertaining to the defined benefit pension plan. Net income for 2013 was less than that of 2012 by approximately $5.3 million primarily due to Royalties (as explained above). The Liability for pension benefits as of December 31, 2013, was eliminated and replaced with Prepaid pension costs, which was a total change from that as of December 31, 2012, of approximately $2.1 million primarily due to the pension contribution made to the plan, an improved actual return achieved during the year within the pension plan portfolio and a higher discount rate applied. Please refer to Note 7 to the Financial Statements for additional pension plan information.

Royalties for 2012 were less than those of 2011 by approximately $2.6 million primarily due to decreased taconite mining on our lands, which accounted for approximately $1.7 million of this total change, and a lower overall average earned royalty rate caused by a higher ratio of mining from our partial fee interest lands versus our full fee interest lands, which accounted for approximately $0.6 million of this total change. Expenses for 2012 were greater than those of 2011 by approximately $0.4 million primarily due to higher pension

5

expense pertaining to the defined benefit pension plan, which accounted for approximately $0.2 million of this total change, and additional amortization of surface lands associated with mining, which accounted for approximately $0.1 million of this total change. Net income for 2012 was less than that of 2011 by approximately $3.0 million primarily due to Royalties (as explained above). The Liability for pension benefits as of December 31, 2012, was less than that as of December 31, 2011, by approximately $0.1 million primarily due to an improved actual return achieved during the year within the pension plan portfolio. Please refer to Note 7 to the Financial Statements for additional pension plan information.

Distributions are mainly a function of Net income (as explained above) and will fluctuate based on income earned, which is primarily dependent on Royalties (as explained above) received from taconite mining on our lands under the control of the mining companies (lessees).

The Trustees declared four quarterly distributions in 2013 totaling $10.00 per share. The first, in the amount of $2.25 per share, was paid on April 30, 2013, to certificate holders of record on March 28, 2013; the second, in the amount of $2.50 per share, was paid on July 31, 2013, to certificate holders of record on June 28, 2013; the third, in the amount of $2.60 per share, was paid on October 31, 2013, to certificate holders of record on September 30, 2013; and the fourth, in the amount of $2.65 per share, was paid on January 31, 2014, to certificate holders of record on December 31, 2013.

The Trustees declared four quarterly distributions in 2012 totaling $14.00 per share. The first, in the amount of $2.25 per share, was paid on April 30, 2012, to certificate holders of record on March 30, 2012; the second, in the amount of $3.00 per share, was paid on July 31, 2012, to certificate holders of record on June 29, 2012; the third, in the amount of $3.50 per share, was paid on October 31, 2012, to certificate holders of record on September 28, 2012; and the fourth, in the amount of $5.25 per share, was paid on January 31, 2013, to certificate holders of record on December 31, 2012.

The Trustees will continue quarterly distributions until the termination date of the Trust and set the record date as of the last business day of each quarter. The next distribution will be paid April 30, 2014, to certificate holders of record on March 31, 2014. The final quarterly distribution to certificate holders representing the last full quarter of business prior to the termination date of the Trust will be for the quarter ending March 31, 2015.

Liquidity: In the interest of preservation of principal of Court-approved reserves and guided by the restrictive provisions of Section 646 of the Tax Reform Act of 1986, as amended, monies are invested primarily in United States Treasury securities with maturity dates not to exceed three years and, along with cash flows from operations, are deemed adequate to meet currently foreseeable liquidity needs. The following is a table of the Trust’s contractual obligations as of December 31, 2013:

	Payments Due by Period
	Total		Less than 1 year		1 – 3 years		3 – 5 years		More than 5 years
Deferred compensation	$	244,300	$	—	$	244,300	$	—	$	—

Critical Accounting Policies: Royalties from the Trust’s mineral leases are taken into income as earned. Tonnage extracted is agreed upon between Trust and lessee engineers based on various engineering methods, which include truck counts, volumetric surveys and blast pattern estimates. Many of the leases provide for escalation or de-escalation that, for the most part, is based on independent producer price indices as published by the U.S. Department of Labor — Bureau of Labor Statistics. In addition, a number of the Trust’s leases have minimum royalty provisions that require the lessee to remit to the Trust current year rental or minimum royalty income for holding the leasehold interest, regardless of production. These minimum royalties can accumulate and do allow the steel and mining companies the ability to offset royalties, over the minimum royalty requirements, due on future taconite production. Minimum royalties, if not recovered before the termination of the lease, are forfeitable and are not refundable under any circumstance.

Pension plan valuations are based on a number of assumptions used to determine the benefit obligation and net periodic pension cost. These assumptions are evaluated annually by the Trustees and management in conjunction with outside actuaries. Assumptions affecting the pension plan valuations include the discount rate, compensation increase level and expected long-term rate of return on plan assets. These assumptions reflect and incorporate the expected cash flow payouts of the pension plan given the determinate time frame to the termination of the Trust. Please refer to Note 7 to the Financial Statements for additional pension plan information.

The Principal Charges account represents a first and prior lien of certificate holders on any property transferable to the reversioner at the end of the Trust and reflects an allocation of beneficiaries’ equity between the certificate holders and the reversioner. This Court-ordered account is neither an asset nor a liability of the Trust. Rather, this account maintains and represents a balance that will be payable to the certificate holders of record from the reversioner at the end of the Trust. The account balance, as stated in Note 6 to the Financial Statements, primarily represents the costs of acquiring homes and surface lands in accordance with provisions of a lease with U.S. Steel Corporation, as well as Court-ordered attorneys’ fees and expenses. This account balance, which may increase or decrease, will be added to the cash distributable to the certificate holders of record at the termination of the Trust.

Forward-Looking and Cautionary Statements: Certain expectations and projections regarding future performance of the Trust 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 the Trust’s control. We caution readers that in addition to factors described elsewhere in this report, the following factors and comments, among others, could cause the Trust’s operations and financial results to differ materially from the expectations and projections contained in the forward-looking statements.

The Trust’s lessees (customers) primarily include Minntac (“Minntac”) and Keetac (“Keetac”), both owned and operated by U.S. Steel Corporation; Hibbing Taconite Company (“Hibtac”), owned by ArcelorMittal, Cliffs Natural Resources Inc. and U.S. Steel Corporation, and operated by Cliffs Mining Company; and Essar Steel Minnesota, LLC (“ESM”), owned by Essar Steel Holdings Ltd., a subsidiary of Essar Global Ltd., which

7

includes a new taconite mining plant (and a future steelmaking facility) currently being constructed by ESM with a projected startup date in late 2014 or early 2015. Because the Trust’s revenues are primarily dependent upon a limited number of customers, any significant adverse event at any of the Trust’s primary lessees, or the loss of any of the Trust’s primary lessees, could materially adversely affect the Trust’s future financial results.

A decline in market demand for steel, and correspondingly taconite, could adversely affect the Trust’s financial results. However, other related and sometimes compensating factors include the Trust’s lessees’ operating levels, minimum royalties, ore body quality, metallurgical and geological characteristics, and location of Trust lands. Also sometimes affecting taconite production from Trust lands are extreme weather conditions and labor contracts at the mines. Though the Trust is not a party to the labor contracts, all pertinent labor contracts affecting production from Trust 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, 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.

Royalty rates can fluctuate due to the escalation and de-escalation of producer price indices as a result of provisions present in many of the Trust’s leases. To the extent these indices decline (the “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.

Compliance with Section 646 of the Internal Revenue Code, as explained in Note 8 to the Financial Statements, is integral to the level of distributions paid to the certificate holders. Should it be determined that the Trust violated the requirements of Section 646, it would be taxed as a corporation versus a grantor trust. This would mean the Trust’s income would be taxable upon receipt by the Trust 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.

As previously reported, the termination date of the Trust is April 6, 2015. Accordingly, acknowledging the downward movement of the share price of certificates of beneficial interest in early 2014, we remind certificate holders that there will be remaining only four regular quarterly distributions declared in the year 2014 and one regular quarterly distribution declared in the year 2015. While there will be some income allocated to the second quarter of 2015 (representing six days of business), it is expected that this amount will be nominal and will likely be included with the final distribution to certificate holders, which final distribution will occur upon the completion of the wind-down process of the Trust and upon approval of the Trust’s final accounting by the Judge of the Ramsey County District Court. As described earlier in this report, upon termination of the Trust on April 6, 2015, the certificates of beneficial interest (shares) will be cancelled and have no further value other than the final distribution.

MANAGEMENT’S REPORT ON

INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Great Northern Iron Ore Properties (the “Trust”) is responsible for establishing and maintaining adequate internal control over financial reporting. The Trust’s internal control system was designed to provide reasonable assurance to the Trust’s management and Board of Trustees regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The Trust’s management assessed the effectiveness of the Trust’s internal control over financial reporting as of December 31, 2013. In making this assessment, it used the criteria set forth in a report by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) titled Internal Control – Integrated Framework (1992 framework). Based on our assessment, we believe that, as of December 31, 2013, the Trust’s internal control over financial reporting is effective based on the COSO criteria.

The Trust’s Independent Registered Public Accounting Firm, Ernst & Young LLP, has issued an audit report on the Trust’s internal control over financial reporting. This report appears on pages 26 and 27.

GREAT NORTHERN IRON ORE PROPERTIES

NOTES TO FINANCIAL STATEMENTS
December 31, 2013

NOTE 1 – BUSINESS AND NATURE OF OPERATIONS

          Great Northern Iron Ore Properties (the “Trust”) is presently involved solely with the leasing and maintenance of mineral and nonmineral lands owned by the Trust on the Mesabi Iron Range in northeastern Minnesota. The Trust 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 (the “Court”) in Saint Paul, Minnesota. Royalties are derived from taconite production and minimums. Royalties (which are not in direct ratio to tonnage shipped) from two significant operating lessees were approximately as follows: 2013 — $10,198,000 and $6,638,000; 2012 — $11,469,000 and $10,625,000; and 2011 — $13,685,000 and $11,334,000.

NOTE 2 – TRUST TERMINATION

          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.

          Upon the termination date 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 Trust termination and after the wind-down process is completed, 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 incurred through the Trust’s termination and wind-down process), plus the balance in the Principal Charges account (see Note 6), all of which are subject to the final accounting and approval of the Ramsey County District Court. 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), without further payment or remuneration to the certificate holders, under the terms of the Trust Agreement. The wind-down process of the Trust is anticipated to extend into the calendar year following its termination date in order to complete the various year-end audits, court and regulatory filings, tax returns, conveyances of non-cash properties to the reversioner, etc., relative thereto. Subject to the guidance and approval of the Ramsey County District Court and assuming the wind-down process with the reversioner proceeds efficiently and that no other complications arise during this time period, we anticipate the wind-down process, final distribution and dissolution of the Trust will be completed by the end of 2016.

16

NOTE 2 – TRUST TERMINATION (CONTINUED)

          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 less properties) and the balance in the Principal Charges account, less any and all expenses and obligations incurred through the Trust’s termination and wind-down process. To offer a hypothetical example, without factoring in any expenses and obligations incurred through the Trust’s termination and wind-down process, and using the financial statement values as of December 31, 2013, the net monies were approximately $9,790,000 and the Principal Charges account balance was approximately $4,789,000, resulting in a final distribution payable of approximately $14,579,000, or about $9.72 per share. Upon the termination of the Trust, the certificates of beneficial interest (shares) would be cancelled and have no further value with the exception of the final distribution. 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 process of the Trust is completed. 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.

NOTE 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.

          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 1, 2013, certificate holders of record as of December 31, 2012, and the reversioner were notified of a hearing on May 8, 2013, in Ramsey County District Court, Saint Paul, Minnesota, for the purpose of settling and allowing the Trust accounts for the year 2012. By Court Order signed and dated May 8, 2013, the 2012 accounts were settled and allowed in all respects. By previous Orders, the Court settled and allowed the accounts of the Trustees for preceding years of the Trust.

17

NOTE 4 – SIGNIFICANT ACCOUNTING POLICIES

          Cash and Cash Equivalents: The Trust considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents.

          Securities: United States Treasury securities are classified as held-to-maturity securities and are carried at cost, adjusted for accrued interest and amortization of premium or discount. The aggregate fair values listed in the table below are based on quoted prices in active markets for identical assets (Level 1). Securities classified as noncurrent assets will mature in 2015. Following is a summary of the securities as of December 31:

	Current						Noncurrent
	2013			2012			2013			2012
Aggregate fair value	$	5,457,842		$	8,416,447		$	2,880,219		$	4,282,664
Gross unrealized holding gains		(1,279	)		(3,707	)		(442	)		(698	)
Gross unrealized holding losses		26			—			294			1,405
Amortized cost basis		5,456,589			8,412,740			2,880,071			4,283,371
Accrued interest		12,086			15,067			3,180			12,086
Amounts shown on balance sheets	$	5,468,675		$	8,427,807		$	2,883,251		$	4,295,457

          Mineral and Surface Lands: Mineral and surface lands are carried at amounts that represent, principally, either costs at acquisition or values on March 1, 1913, net of accumulated amortization. The value of the merchantable ore deposits was established on March 1, 1913, for federal income tax purposes. No value has been estimated or recorded for taconite deposits held on March 1, 1913, since they were not then thought to be merchantable; however, they presently represent all the mining activity on the Trust’s properties. Mineral lands are being amortized on the straight-line method over the remaining term of the Trust. The straight-line method of amortization bears close resemblance to the units-of-production method over the remaining term of the Trust and, accordingly, is deemed a reasonable, systematic and rational method to associate expense with the revenues generated from taconite mining. Mineral land amortization amounted to $294,000, $295,200 and $294,000 for the years 2013, 2012 and 2011, respectively. Nonmineral lands are also included in this category; however, they represent negligible amounts.

          In addition, surface lands are acquired from time to time to facilitate mining operations (see Note 5). These surface lands are being amortized on a straight-line basis over the remaining term of the Trust based on the values as of the beginning of each fiscal year. Surface lands remaining to be amortized amounted to $901,085, $1,301,885 and $1,242,035 as of January 1, 2013, 2012 and 2011, respectively. Surface land amortization amounted to $400,800, $400,800 and $292,800 for the years 2013, 2012 and 2011, respectively.

          Royalties: Royalties from mineral leases (with cancellation terms varying from six months to one year) are taken into income as earned. Earned royalties are based on the taconite tonnage extracted (also referred to as produced or shipped) from the Trust’s lands applied to a royalty rate as defined in the various specific and confidential operating agreements (also referred to as leases). Minimum royalties, if required, are current year’s rental or minimum royalty income from the lessees to the Trust for holding the leasehold interest. Certain leases provide the steel and mining companies the ability to offset royalties, over the minimum royalty requirements, due on future taconite production, if any and when

18

NOTE 4 – SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

mined, against unabsorbed minimum royalties paid in prior periods. Accumulated minimum royalties from mineral leases in excess of tons extracted to date amounted to $11,050,845 and $9,279,941 as of December 31, 2013 and 2012, respectively.

          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 amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

          Earnings per Share: Earnings per share are determined by dividing net income for the period by the number of weighted-average shares of beneficial interest outstanding. Basic and diluted weighted-average shares outstanding were 1,500,000 as of December 31, 2013, 2012 and 2011.

NOTE 5 – LAND ACQUISITION

          A mining agreement dated January 1, 1959, with U.S. Steel Corporation provides that one-half of annual earned royalties, after satisfaction of minimum royalty payments, shall be applied, in lieu of royalty payments, to reimburse the lessee for a portion of its cost of acquisition of surface lands overlying the leased mineral deposits, which surface lands are then conveyed to the Trustees (see Note 4). The costs of surface lands acquired to facilitate the mining operations amounted to $0, $0 and $352,650 for the years 2013, 2012 and 2011, respectively. There are surface lands yet to be purchased, the costs of which are yet unknown and will not be known until the actual purchases are made.

NOTE 6 – PRINCIPAL CHARGES ACCOUNT

          Pursuant to the Court Order of November 29, 1982, the Trustees were directed to create and maintain an account designated as “Principal Charges.” This account constitutes a first and prior lien of certificate holders on any property transferable to the reversioner and reflects an allocation of beneficiaries’ equity between the certificate holders and the reversioner. This account is neither an asset nor a liability of the Trust. Rather, this account maintains and represents a balance that will be payable to the certificate holders of record from the reversioner at the end of the Trust. The balance in this account consists of attorneys’ fees and expenses of counsel for adverse parties pursuant to the Court Order in connection with litigation commenced in 1972 relating to the Trustees’ powers and duties under the Trust Agreement and the costs of homes and surface lands acquired in accordance with provisions of a lease with U.S. Steel Corporation, net of an allowance to amortize the cost of the land based on actual shipments of taconite and net of a credit for disposition of tangible assets.

          Following is an analysis of this account for the years ended as of:

	2013			2012
Attorneys’ fees and expenses	$	1,024,834		$	1,024,834
Costs of surface lands		6,606,815			6,606,815
Cumulative shipment credits		(2,471,015	)		(2,388,760	)
Cumulative asset disposition credits		(372,124	)		(372,124	)
Principal Charges account balance	$	4,788,510		$	4,870,765

19

NOTE 6 – PRINCIPAL CHARGES ACCOUNT (CONTINUED)

          Upon termination of the Trust, the Trustees shall either sell tangible assets or obtain a loan with tangible assets as security to provide monies for distribution to the certificate holders in the amount of the Principal Charges account balance.

NOTE 7 – PENSION PLAN

          The Trust has a noncontributory defined benefit pension plan that covers all employees. The Trustees are not eligible for pension benefits under the plan based on their services as Trustees. The pension accounting guidance requires employers with pension plans to recognize the funded (or unfunded) status of a plan on the face of the balance sheet. The funded status is determined by comparing the pension plan assets at fair value to the projected (future) benefit obligation.

          A summary of the components of net periodic pension cost and other amounts recognized in other comprehensive income is as follows:

Net Periodic Pension Cost	2013			2012			2011
Service cost	$	325,693		$	306,799		$	279,647
Interest cost		307,871			322,198			319,860
Expected return on assets		(537,923	)		(448,470	)		(433,591	)
Amortization of net loss		663,536			492,391			306,348
Amortization of prior service cost		17,469			17,469			17,469
Net periodic pension cost		776,646			690,387			489,733
Other Changes in Plan Assets and Benefit Obligations Recognized in Other Comprehensive Income
Net (gain) loss arising during the period		(879,193	)		488,972			678,007
Amortization of net loss included in net periodic pension cost		(663,536	)		(492,391	)		(306,348	)
Amortization of prior service cost included in net periodic pension cost		(17,469	)		(17,469	)		(17,469	)
Total (gain) loss recognized in other comprehensive income		(1,560,198	)		(20,888	)		354,190
Total recognized in net periodic pension cost and other comprehensive income	$	(783,552	)	$	669,499		$	843,923

          A summary of the weighted-average assumptions used in the measurement of the benefit obligation and the net periodic pension cost is as follows:

	2013		2012
Discount rate for benefit obligation	4.25	%	3.50	%
Discount rate for net periodic pension cost	3.50	%	4.15	%
Rate of compensation increase	3.50	%	3.50	%
Expected long-term return on plan assets	2.30	%	7.00	%

          The determination of the discount rate is based on the Citigroup pension yield curve that approximates the expected cash flow payouts of the plan, coupled with a comparison to the Moody’s Long-term Corporate Aa Bond Yield. The determination of the rate of compensation increase is based on historical salary adjustment averages and the Trustees’ expectations of future increases. The determination of the expected long-term return on plan

20

NOTE 7 – PENSION PLAN (CONTINUED)

assets is based on a revised investment policy effective in 2013 that reduces exposure to equities given the termination of the Trust on April 6, 2015.

          A summary of the changes in projected benefit obligation is as follows:

	2013			2012
Projected benefit obligation at beginning of year	$	8,942,161		$	7,903,211
Service cost		325,693			306,799
Interest cost		307,871			322,198
Actuarial (gain) loss		(624,138	)		692,835
Benefit payments		(273,393	)		(282,882	)
Projected benefit obligation at end of year	$	8,678,194		$	8,942,161

          A summary of the changes in the fair value of plan assets is as follows:

	2013			2012
Fair value of plan assets at beginning of year	$	7,430,467		$	6,261,098
Contributions by the Trust		1,315,301			799,918
Actual return on plan assets		792,978			652,333
Benefit payments		(273,393	)		(282,882	)
Fair value of plan assets at end of year	$	9,265,353		$	7,430,467

          A summary of the plan’s funded (unfunded) status and amounts recognized in the balance sheets shown as “Prepaid pension costs” or “Liability for pension benefits” is as follows:

	2013		2012
Accumulated benefit obligation at end of year	$	6,737,531	$	6,830,628
Effect of future compensation increases		1,940,663		2,111,533
Projected benefit obligation at end of year		8,678,194		8,942,161
Fair value of plan assets at end of year		9,265,353		7,430,467
Funded (unfunded) status at end of year	$	587,159	$	(1,511,694	)

          A summary of the amounts recognized in the balance sheets shown as “Accumulated other comprehensive loss” is as follows:

	2013		2012
Net loss	$	844,444	$	2,387,173
Prior service cost		17,467		34,936
Accumulated other comprehensive loss	$	861,911	$	2,422,109

          The net loss and prior service cost amounts that will be amortized from “Accumulated other comprehensive loss” into net periodic pension cost in 2014 are estimated to be $0 and $17,467, respectively.

21

NOTE 7 – PENSION PLAN (CONTINUED)

          A summary of the estimated future benefit payments from the plan for the next ten year period is as follows:

Period	Amount
2014	$	277,287
2015		828,230
2016		817,372
2017		793,994
2018		767,229
2019 - 2023		3,390,247

          The 2014 contribution to the plan is estimated to approximate $1,400,000, representing the maximum contribution that is recommended pursuant to the Trust’s annual actuarial valuation. However, the actual 2014 contribution will not be determined and finalized until after the completion of the plan’s annual actuarial valuation, which is performed as of the plan’s fiscal year end, March 31.

          The investment policy of the plan was revised in 2013 to reduce the exposure to equities given the termination date of the Trust on April 6, 2015. A sliding scale was adopted that adjusts the plan portfolio maximum allocation of equities downward on a quarterly basis. As of December 31, 2013, said policy permits up to approximately 37% of the plan portfolio invested in equity securities (via the S&P 500 Exchange Traded Fund) and the remaining monies invested in fixed income (debt) securities and cash. The equity portfolio strategy is to generate appreciation and growth in the plan’s overall value over the long-term with its benchmark being the S&P 500 Index. The debt portfolio strategy is to generate income for the payment of benefits, as well as investment diversification with its benchmark being the Barclays Capital Government/Credit Index. The cash portfolio strategy is to provide liquidity for the payment of benefits to current retirees. The fair value measurements are based on quoted prices in active markets for identical assets (Level 1).

          A summary of the plan’s weighted-average asset allocations by category is as follows:

	2013					2012
	Fair Value		%			Fair Value		%
Equity securities	$	3,441,055		37	%	$	3,675,700		49	%
Debt securities – corporate issues		4,817,000		52			2,552,642		34
Debt securities – U.S. government issues		931,384		10			996,873		14
Cash (money market, accrued income)		75,914		1			205,252		3
Total	$	9,265,353		100	%	$	7,430,467		100	%

NOTE 8 – INCOME TAXES

          The Trustees filed an election under Section 646 of the Tax Reform Act of 1986, as amended. As discussed in Note 3, beginning in 1989 the Trust is no longer subject to federal or Minnesota corporate income taxes, provided the requirements of Section 646 are met. The principal requirements are:

• The Trust must be exclusively engaged in the leasing of mineral properties and activities incidental thereto.

22

NOTE 8 – INCOME TAXES (CONTINUED)

• The Trust must not acquire any additional property other than permissible acquisitions as provided by Section 646.

          If these requirements are violated, the Trust will be treated as a corporation for the taxable year in which the violation occurs and for all subsequent taxable years. Since the election of Section 646, the Trust has remained in compliance with these requirements.

NOTE 9 – LEASE COMMITMENTS

NOTE 12 – NEW ACCOUNTING PRONOUNCEMENT

          In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2013-02, Comprehensive Income (Topic 220) – Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This ASU amends Accounting Standards Codification Topic 220 for the purpose of requiring the reporting of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amounts being reclassified are required under U.S. generally accepted accounting principles to be reclassified in their entirety to net income. This amendment does not change the current requirements for reporting net income or other comprehensive income in the financial statements. Rather, this amendment requires more information about the amounts reclassified out of accumulated other comprehensive income by component, with this additional information either shown on the face of the income statement or within the notes to the financial statements. For public companies, this ASU is effective for periods beginning after December 15, 2012. The Trust adopted this amendment required by ASU No. 2013-02 beginning with its first quarter in 2013, and has elected to present the required information within the notes to the financial statements.

REPORT OF ERNST & YOUNG LLP,
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM,
ON AUDIT OF FINANCIAL STATEMENTS

The Trustees
Great Northern Iron Ore Properties

          We have audited the accompanying balance sheets of Great Northern Iron Ore Properties (the Trust) as of December 31, 2013 and 2012, and the related statements of beneficiaries’ equity, income, comprehensive income and cash flows for each of the three years in the period ended December 31, 2013. 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 (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 financial position of the Trust at December 31, 2013 and 2012, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2013, in conformity with U.S. generally accepted accounting principles.

          As discussed in Note 2 to the financial statements, the Trust terminates on April 6, 2015.

          We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Great Northern Iron Ore Properties’ internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework), and our report dated February 20, 2014, expressed an unqualified opinion thereon.

REPORT OF ERNST & YOUNG LLP,
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM,
ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Trustees
Great Northern Iron Ore Properties

          We have audited Great Northern Iron Ore Properties’ (the Trust) internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992 framework) (the COSO criteria). The Trust’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Trust’s internal control over financial reporting based on our audit.

          We conducted our audit 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 effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

          A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

26

          Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

          In our opinion, the Trust maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the COSO criteria.

          We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 2013 financial statements of Great Northern Iron Ore Properties, and our report dated February 20, 2014, expressed an unqualified opinion thereon.

Report of Audit Committee

GREAT NORTHERN IRON ORE PROPERTIES
Report of Audit Committee
Year Ended December 31, 2013

The Audit Committee oversees the Trust’s financial reporting process on behalf of the Board of Trustees. Management has the primary responsibility for the financial statements and the reporting process including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited financial statements in the Annual Report with management including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements.

The Audit Committee reviewed with the independent auditors, who are responsible for expressing an opinion on the conformity of those audited financial statements with accounting principles generally accepted in the United States, their judgments as to the quality, not just the acceptability, of the Trust’s accounting principles and such other matters as are required to be discussed with the Audit Committee under auditing standards generally accepted in the United States. In addition, the Audit Committee has discussed with the independent auditors the auditors’ independence from management and the Trust including the matters in the written disclosures required by the Independence Standards Board.

The Audit Committee discussed with the Trust’s independent auditors the overall scope and plans for their audit. The Audit Committee met with the independent auditors, with and without management present, to discuss the results of their examination, their evaluation of the Trust’s internal controls and the overall quality of the Trust’s financial reporting.

The Board of Trustees accepted the Audit Committee’s reappointment of Ernst & Young LLP as independent auditors of the financial statements of the Trust for the year 2013. All audit and non-audit services (printing and reproduction services) were preapproved by the Audit Committee. Fees paid in 2013 for the annual audit services were $90,400, for audit-related services were $1,600, for tax services were $0 and for all other services were $3,000. Fees paid in 2012 for the annual audit services were $86,700, for audit-related services were $1,600, for tax services were $0 and for all other services were $3,000.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Trustees that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2013, for filing with the Securities and Exchange Commission.

NOTES TO FINANCIAL STATEMENTS

December 31, 2013

NOTE 1 – Business And Nature of Operations

Great Northern Iron Ore Properties (the “Trust”) is presently involved solely with the leasing and maintenance of mineral and nonmineral lands owned by the Trust on the Mesabi Iron Range in northeastern Minnesota.  The Trust 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 (the “Court”) in Saint Paul, Minnesota.  Royalties are derived from taconite production and minimums.  Royalties (which are not in direct ratio to tonnage shipped) from two significant operating lessees were approximately as follows: 2013 — $10,198,000 and $6,638,000; 2012 — $11,469,000 and $10,625,000; and 2011 — $13,685,000 and$11,334,000.

NOTE 4 – Significant Accounting Policies

Cash and Cash Equivalents: The Trust considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents.

Securities: United States Treasury securities are classified as held-to-maturity securities and are carried at cost, adjusted for accrued interest and amortization of premium or discount.  The aggregate fair values listed in the table below are based on quoted prices in active markets for identical assets (Level 1).  Securities classified as noncurrent assets will mature in 2015.  Following is a summary of the securities as of December 31:

	Current				Noncurrent
	2013		2012		2013		2012
Aggregate fair value	$	5,457,842	$	8,416,447	$	2,880,219	$	4,282,664
Gross unrealized holding gains		(1,279)		(3,707)		(442)		(698)
Gross unrealized holding losses		26		-		294		1,405
Amortized cost basis		5,456,589		8,412,740		2,880,071		4,283,371
Accrued interest		12,086		15,067		3,180		12,086
Amounts shown on balance sheets	$	5,468,675	$	8,427,807	$	2,883,251	$	4,295,457

Mineral and Surface Lands:  Mineral and surface lands are carried at amounts that represent, principally, either costs at acquisition or values on March 1, 1913, net of accumulated amortization.  The value of the merchantable ore deposits was established on March 1, 1913, for federal income tax purposes.  No value has been estimated or recorded for taconite deposits held on March 1, 1913, since they were not then thought to be merchantable; however, they presently represent all the mining activity on the Trust’s properties.  Mineral lands are being amortized on the straight-line method over the remaining term of the Trust.  The straight-line method of amortization bears close resemblance to the units-of-production method over the remaining term of the Trust and, accordingly, is deemed a reasonable, systematic and rational method to associate expense with the revenues generated from taconite mining.  Mineral land amortization amounted to $294,000,  $295,200 and $294,000 for the years 2013, 2012 and 2011, respectively.  Nonmineral lands are also included in this category; however, they represent negligible amounts.

In addition, surface lands are acquired from time to time to facilitate mining operations (see Note 5).  These surface lands are being amortized on a straight-line basis over the remaining term of the Trust based on the values as of the beginning of each fiscal year.  Surface lands remaining to be amortized amounted to $901,085,  $1,301,885 and $1,242,035 as of January 1, 2013, 2012 and 2011, respectively.  Surface land amortization amounted to $400,800,  $400,800 and $292,800 for the years 2013, 2012 and 2011, respectively.

NOTE 4 – Significant Accounting Policies(continued)

Royalties:  Royalties from mineral leases (with cancellation terms varying from six months to one year) are taken into income as earned.  Earned royalties are based on the taconite tonnage extracted (also referred to as produced or shipped) from the Trust’s lands applied to a royalty rate as defined in the various specific and confidential operating agreements (also referred to as leases).  Minimum royalties, if required, are current year’s rental or minimum royalty income from the lessees to the Trust for holding the leasehold interest.  Certain leases provide the steel and mining companies the ability to offset royalties, over the minimum royalty requirements, due on future taconite production, if any and when mined, against unabsorbed minimum royalties paid in prior periods.  Accumulated minimum royalties from mineral leases in excess of tons extracted to date amounted to $11,050,845 and $9,279,941 as of December 31, 2013 and 2012, respectively.

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 amounts reported in the financial statements and accompanying notes.  Actual results could differ from those estimates.

Earnings per Share:  Earnings per share are determined by dividing net income for the period by the number of weighted-average shares of beneficial interest outstanding.  Basic and diluted weighted-average shares outstanding were 1,500,000 as of December 31, 2013, 2012 and 2011.

Legal Proceedings

NOTE 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.

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 1, 2013, certificate holders of record as of December 31, 2012, and the reversioner were notified of a hearing on May 8, 2013, in Ramsey County District Court, Saint Paul, Minnesota, for the purpose of settling and allowing the Trust accounts for the year 2012.  By Court Order signed and dated May 8, 2013, the 2012 accounts were settled and allowed in all respects.  By previous Orders, the Court settled and allowed the accounts of the Trustees for preceding years of the Trust.

Pension Plan [Abstract]

Pension Plan

NOTE 7 – Pension Plan

The Trust has a noncontributory defined benefit pension plan that covers all employees. The Trustees are not eligible for pension benefits under the plan based on their services as Trustees.  The pension accounting guidance requires employers with pension plans to recognize the funded (or unfunded) status of a plan on the face of the balance sheet.  The funded status is determined by comparing the pension plan assets at fair value to the projected (future) benefit obligation.

A summary of the components of net periodic pension cost and other amounts recognized in other comprehensive income is as follows:

Net Periodic Pension Cost	2013		2012		2011
Service cost	$	325,693	$	306,799	$	279,647
Interest cost		307,871		322,198		319,860

Total recognized in net periodic pension cost      and other comprehensive income	$	(783,552)	$	669,499	$	843,923

NOTE 7 –  Pension  Plan(continued)

A summary of the weighted-average assumptions used in the measurement of the benefit obligation and the net periodic pension cost is as follows:

	2013		2012
Discount rate for benefit obligation	4.25	%	3.50	%
Discount rate for net periodic pension cost	3.50	%	4.15	%
Rate of compensation increase	3.50	%	3.50	%
Expected long-term return on plan assets	2.30	%	7.00	%

The determination of the discount rate is based on the Citigroup pension yield curve that approximates the expected cash flow payouts of the plan, coupled with a comparison to the Moody’s Long-term Corporate Aa Bond Yield.  The determination of the rate of compensation increase is based on historical salary adjustment averages and the Trustees’ expectations of future increases.  The determination of the expected long-term return on plan assets is based on a revised investment policy effective in 2013 that reduces exposure to equities given the termination of the Trust on April 6, 2015.

A summary of the changes in projected benefit obligation is as follows:

	2013		2012
Projected benefit obligation at beginning of year	$	8,942,161	$	7,903,211
Service cost		325,693		306,799
Interest cost		307,871		322,198
Actuarial (gain) loss		(624,138)		692,835
Benefit payments		(273,393)		(282,882)
Projected benefit obligation at end of year	$	8,678,194	$	8,942,161

A summary of the changes in the fair value of plan assets is as follows:

	2013		2012
Fair value of plan assets at beginning of year	$	7,430,467	$	6,261,098
Contributions by the Trust		1,315,301		799,918
Actual return on plan assets		792,978		652,333
Benefit payments		(273,393)		(282,882)
Fair value of plan assets at end of year	$	9,265,353	$	7,430,467

A summary of the plan’s funded (unfunded) status and amounts recognized in the balance sheets shown as “Prepaid pension costs” or “Liability for pension benefits” is as follows:

	2013		2012
Accumulated benefit obligation at end of year	$	6,737,531	$	6,830,628
Effect of future compensation increases		1,940,663		2,111,533
Projected benefit obligation at end of year		8,678,194		8,942,161
Fair value of plan assets at end of year		9,265,353		7,430,467
Funded (unfunded) status at end of year	$	587,159	$	(1,511,694)

NOTE 7 –  Pension  Plan(continued)

A summary of the amounts recognized in the balance sheets shown as “Accumulated other comprehensive loss” is as follows:

	2013		2012
Net loss	$	844,444	$	2,387,173
Prior service cost		17,467		34,936
Accumulated other comprehensive loss	$	861,911	$	2,422,109

The net loss and prior service cost amounts that will be amortized from “Accumulated other comprehensive loss” into net periodic pension cost in 2014 are estimated to be $0 and $17,467, respectively.

A summary of the estimated future benefit payments from the plan for the next ten year period is as follows:

Period	Amount
2014	$	277,287
2015		828,230
2016		817,372
2017		793,994
2018		767,229
2019 - 2023		3,390,247

The 2014 contribution to the plan is estimated to approximate $1,400,000, representing the maximum contribution that is recommended pursuant to the Trust’s annual actuarial valuation.  However, the actual 2014 contribution will not be determined and finalized until after the completion of the plan’s annual actuarial valuation, which is performed as of the plan’s fiscal yearend, March 31.

The investment policy of the plan was revised in 2013 to reduce the exposure to equities given the termination date of the Trust on April 6, 2015.  A sliding scale was adopted that adjusts the plan portfolio maximum allocation of equities downward on a quarterly basis.  As of December 31, 2013, said policy permits up to approximately 37% of the plan portfolio invested in equity securities (via the S&P 500 Exchange Traded Fund) and the remaining monies invested in fixed income (debt) securities and cash.  The equity portfolio strategy is to generate appreciation and growth in the plan’s overall value over the long-term with its benchmark being the S&P 500 Index.  The debt portfolio strategy is to generate income for the payment of benefits, as well as investment diversification with its benchmark being the Barclays Capital Government/Credit Index.  The cash portfolio strategy is to provide liquidity for the payment of benefits to current retirees.  The fair value measurements are based on quoted prices in active markets for identical assets (Level 1). 

A summary of the plan’s weighted-average asset allocations by category is as follows:

	2013				2012
	Fair Value		%		Fair Value		%
Equity securities	$	3,441,055	37	%	$	3,675,700	49	%
Debt securities - corporate issues		4,817,000	52			2,552,642	34

Land Acquisition

NOTE 5 – Land Acquisition

A mining agreement dated January 1, 1959, with U.S. Steel Corporation provides that one-half of annual earned royalties, after satisfaction of minimum royalty payments, shall be applied, in lieu of royalty payments, to reimburse the lessee for a portion of its cost of acquisition of surface lands overlying the leased mineral deposits, which surface lands are then conveyed to the Trustees (see Note 4).  The costs of surface lands acquired to facilitate the mining operations amounted to $0,  $0 and $352,650 for the years 2013, 2012 and 2011, respectively.  There are surface lands yet to be purchased, the costs of which are yet unknown and will not be known until the actual purchases are made.

Principal Charges Account

NOTE 6 – Principal Charges Account

Pursuant to the Court Order of November 29, 1982, the Trustees were directed to create and maintain an account designated as “Principal Charges.”  This account constitutes a first and prior lien of certificate holders on any property transferable to the reversioner and reflects an allocation of beneficiaries’ equity between the certificate holders and the reversioner.  This account is neither an asset nor a liability of the Trust.  Rather, this account maintains and represents a balance that will be payable to the certificate holders of record from the reversioner at the end of the Trust.  The balance in this account consists of attorneys’ fees and expenses of counsel for adverse parties pursuant to the Court Order in connection with litigation commenced in 1972 relating to the Trustees’ powers and duties under the Trust Agreement and the costs of homes and surface lands acquired in accordance with provisions of a lease with U.S. Steel Corporation, net of an allowance to amortize the cost of the land based on actual shipments of taconite and net of a credit for disposition of tangible assets.

NOTE 8 – Income Taxes

The Trustees filed an election under Section 646 of the Tax Reform Act of 1986, as amended. As discussed in Note 3, beginning in 1989 the Trust is no longer subject to federal or Minnesota corporate income taxes, provided the requirements of Section 646 are met.  The principal requirements are:

· The Trust must be exclusively engaged in the leasing of mineral properties and activities incidental thereto.

· The Trust must not acquire any additional property other than permissible acquisitions as provided by Section 646.

If these requirements are violated, the Trust will be treated as a corporation for the taxable year in which the violation occurs and for all subsequent taxable years.  Since the election of Section 646, the Trust has remained in compliance with these requirements.

Mineral and Surface Lands:  Mineral and surface lands are carried at amounts that represent, principally, either costs at acquisition or values on March 1, 1913, net of accumulated amortization.  The value of the merchantable ore deposits was established on March 1, 1913, for federal income tax purposes.  No value has been estimated or recorded for taconite deposits held on March 1, 1913, since they were not then thought to be merchantable; however, they presently represent all the mining activity on the Trust’s properties.  Mineral lands are being amortized on the straight-line method over the remaining term of the Trust.  The straight-line method of amortization bears close resemblance to the units-of-production method over the remaining term of the Trust and, accordingly, is deemed a reasonable, systematic and rational method to associate expense with the revenues generated from taconite mining.  Mineral land amortization amounted to $294,000,  $295,200 and $294,000 for the years 2013, 2012 and 2011, respectively.  Nonmineral lands are also included in this category; however, they represent negligible amounts.

In addition, surface lands are acquired from time to time to facilitate mining operations (see Note 5).  These surface lands are being amortized on a straight-line basis over the remaining term of the Trust based on the values as of the beginning of each fiscal year.  Surface lands remaining to be amortized amounted to $901,085,  $1,301,885 and $1,242,035 as of January 1, 2013, 2012 and 2011, respectively.  Surface land amortization amounted to $400,800,  $400,800 and $292,800 for the years 2013, 2012 and 2011, respectively

Royalties

Royalties:  Royalties from mineral leases (with cancellation terms varying from six months to one year) are taken into income as earned.  Earned royalties are based on the taconite tonnage extracted (also referred to as produced or shipped) from the Trust’s lands applied to a royalty rate as defined in the various specific and confidential operating agreements (also referred to as leases).  Minimum royalties, if required, are current year’s rental or minimum royalty income from the lessees to the Trust for holding the leasehold interest.  Certain leases provide the steel and mining companies the ability to offset royalties, over the minimum royalty requirements, due on future taconite production, if any and when mined, against unabsorbed minimum royalties paid in prior periods.  Accumulated minimum royalties from mineral leases in excess of tons extracted to date amounted to $11,050,845 and $9,279,941 as of December 31, 2013 and 2012, respectively

Use of Estimates

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 amounts reported in the financial statements and accompanying notes.  Actual results could differ from those estimates

Earnings Per Share

Earnings per Share:  Earnings per share are determined by dividing net income for the period by the number of weighted-average shares of beneficial interest outstanding.  Basic and diluted weighted-average shares outstanding were 1,500,000 as of December 31, 2013, 2012 and 2011

Trust Termination [Abstract]

Trust Termination

NOTE 2 – Trust Termination

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.  

Upon the termination date 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 Trust termination and after the wind-down process is completed, 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 incurred through the Trust’s termination and wind-down process), plus the balance in the Principal Charges account (see Note 6), all of which are subject to the final accounting and approval of the Ramsey County District Court.  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), without further payment or remuneration to the certificate holders, under the terms of the Trust Agreement.  The wind-down process of the Trust is anticipated to extend into the calendar year following its termination date in order to complete the various year-end audits, court and regulatory filings, tax returns, conveyances of non-cash properties to the reversioner, etc., relative thereto.  Subject to the guidance and approval of the Ramsey County District Court and assuming the wind-down process with the reversioner proceeds efficiently and that no other complications arise during this time period, we anticipate the wind-down process, final distribution and dissolution of the Trust will be completed by the end of 2016.

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 less properties) and the balance in the Principal Charges account, less any and all expenses and obligations incurred through the Trust’s termination and wind-down process.  To offer a hypothetical example, without factoring in any expenses and obligations incurred through the Trust’s termination and wind-down process, and using the financial statement values as of December 31, 2013, the net monies were approximately $9,790,000 and the Principal Charges account balance was approximately $4,789,000, resulting in a final distribution payable of approximately $14,579,000, or about $9.72 per share.  Upon the termination of the Trust, the certificates of beneficial interest (shares) would be cancelled and have no further

NOTE 2 – Trust Termination (continued)

value with the exception of the final distribution.  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 process of the Trust is completed.  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.

New Accounting Pronouncements

NOTE 12 – New  Accounting  Pronouncement

In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2013-02, Comprehensive Income (Topic 220) – Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.  This ASU amends Accounting Standards Codification Topic 220 for the purpose of requiring the reporting of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amounts being reclassified are required under U.S. generally accepted accounting principles to be reclassified in their entirety to net income.  This amendment does not change the current requirements for reporting net income or other comprehensive income in the financial statements.  Rather, this amendment requires more information about the amounts reclassified out of accumulated other comprehensive income by component, with this additional information either shown on the face of the income statement or within the notes to the financial statements.  For public companies, this ASU is effective for periods beginning after December 15, 2012.  The Trust adopted this amendment required by ASU No. 2013-02 beginning with its first quarter in 2013, and has elected to present the required information within the notes to the financial statements.
