Explanatory Note

On March 30, 2020, Global Self Storage, Inc. (“we”, “us”, “our”, or the “Company”) filed an Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (the “Original Form 10-K”). This Amendment No. 1 on Form 10-K/A (this “Amendment”) is being filed to update the certifications filed as Exhibits 31.1 and 31.2, respectively, to the Original Form 10-K, to include certain required language with respect to internal control over financial reporting which was permitted to be omitted during the Company’s transition period, but was inadvertently omitted subsequent to the Company’s transition period from the Original Form 10-K. There has been no change to (i) the financial statements included in Part II, Item 8 hereof from those included in Part II, Item 8 of the Original Form 10-K, nor (ii) Part II, Item 9A hereof from Part II, Item 9A of the Original Form 10-K.

Except as described above, this Amendment does not modify or update the disclosures presented in the Original Form 10-K or in the previously filed exhibits to the Original Form 10-K in any way. This Amendment speaks as of the date of the Original Form 10-K and does not reflect events occurring after the filing of the Original Form 10-K. As such, this Amendment should be read in conjunction with the Original Form 10-K, as well as any other filings made by the Company with the Securities and Exchange Commission (the “SEC”) pursuant to Section 13(a) or 15(d) of the Exchange Act subsequent to the filing of the Original Form 10-K.

Item 8. Financial Statements and Supplementary Data.

The financial statements are included in this annual report beginning on page F-3.

Item 9A. Controls and Procedures.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures to ensure that information required to be disclosed in the reports we file pursuant to the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based on the definition of “disclosure controls and procedures” in Rule 13a-15(e) of the Exchange Act. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can only provide a reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We have a disclosure controls and procedures committee, comprised of the Chief Executive Officer and Chief Financial Officer, which meets as necessary and is responsible for considering the materiality of information and determining our disclosure obligations on a timely basis.

The disclosure controls and procedures committee carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our board of directors, audit committee, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP and includes those policies and procedures that:

• pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our management and board of directors; and

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

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

Our management, including our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting as of December 31, 2019. In making this assessment, our management used criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013 Framework).

4

Based on this assessment, our management believes that, as of December 31, 2019, our internal control over financial reporting was effective based on those criteria.

Changes in Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(d) and 15d-15(d) under the Exchange Act) that occurred during our fiscal fourth quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Global Self Storage, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Global Self Storage, Inc. and subsidiaries (the Company) as of December 31, 2019, the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for the year then ended, and the related notes and schedule (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

We have served as the Company's auditor since 2019.

GLOBAL SELF STORAGE, INC.

NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION

Global Self Storage, Inc. (the “Company,” “we,” “our,” “us”) is a self-administered and self-managed Maryland real estate investment trust (“REIT”) that owns, operates, manages, acquires, develops and redevelops self storage properties (“stores” or “properties”) in the United States. Through its wholly owned subsidiaries, the Company owns and/or manages 13 self-storage properties in Connecticut, Illinois, Indiana, New York, Ohio, Pennsylvania, South Carolina, and Oklahoma. The Company operates primarily in one segment: rental operations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Upon deregistration as an investment company, effective January 19, 2016, the Company’s status changed to an operating company from an investment company since it no longer met the assessment of an investment company under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946 (“ASC 946”). The Company discontinued applying the guidance in ASC 946 and began to account for the change in status prospectively by accounting for its investments in accordance with other U.S. generally accepted accounting principles (“GAAP”) topics as of the date of the change in status.

The consolidated financial statements of the Company are presented on the accrual basis of accounting in accordance with GAAP and include the accounts of the Company and its wholly owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.

Reclassifications

Certain amounts from the prior year have been reclassified to conform to current year presentation as described below.

Accounting Standards Adopted

In February 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-02 - Leases (Topic 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either financing or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification determines whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less are accounted for similar to previous guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to previous guidance for sales-type leases, direct financing leases and operating leases. The Company adopted the standard on January 1, 2019, the date it became effective for public companies, using the modified retrospective approach whereby the cumulative effect of adoption was recognized on the adoption date and prior periods were not restated. There was no net cumulative effect adjustment to retained earnings as of January 1, 2019 as a result of this adoption. Upon adoption, the Company elected the package of practical expedients permitted within the standard, which among other things, allows for the carryforward of historical lease classification. The Company also elected the practical expedient provided to lessors in a subsequent amendment to the standard that removed the requirement to separate lease and nonlease components, provided certain conditions were met. Refer to note 9 for the impact of the adoption of ASU No. 2016-02 – Leases (Topic 842) on the Company’s consolidated financial statements.

Cash, Cash Equivalents, and Restricted Cash

The Company’s cash is deposited with financial institutions located throughout the United States and at times may exceed federally insured limits. The Company considers all highly liquid investments, which may include

F-8

money market fund shares, with a maturity of three months or less to be cash equivalents. Restricted cash is comprised of escrowed funds deposited with a bank relating to capital expenditures.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash in our consolidated balance sheets to the total amount shown in our consolidated statements of cash flows:

	December 31, 2019		December 31, 2018
Cash and cash equivalents	$	3,990,160	$	1,526,203
Restricted cash		263,405		186,063
Total cash, cash equivalents, and restricted cash as shown in our consolidated statements of cash flows	$	4,253,565	$	1,712,266

Income Taxes

The Company has elected to be treated as a REIT under the IRC. In order to maintain its qualification as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax with respect to that portion of its income which meets certain criteria and is distributed annually to stockholders. The Company plans to continue to operate so that it meets the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. If the Company were to fail to meet these requirements, it would be subject to federal income tax. In managements opinion, the requirements to maintain these elections are being met. The Company is subject to certain state and local taxes.

The Company has elected to treat its corporate subsidiary, SSG TRS LLC, as a taxable REIT subsidiary (“TRS”). In general, the Company’s TRS may perform additional services for tenants and may engage in any real estate or non-real estate related business. A TRS is subject to federal corporate income tax.

The Company recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. The Company has reviewed its tax positions and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on federal, state, and local income tax returns for open tax years (2016 – 2018), or is expected to be taken in the Company’s 2019 tax returns.

Marketable Equity Securities

Investments in equity securities that have readily determinable fair values are accounted for equity securities measured at fair value. Gains or losses from changes in the fair value of equity securities are recorded in net income, until the investment is sold or otherwise disposed. The specific identification method is used to determine the realized gain or loss on investments sold or otherwise disposed.

Fair value is determined using a valuation hierarchy generally by reference to an active trading market, using quoted closing or bid prices. Judgment is used to ascertain if a formerly active market has become inactive and in determining fair values when markets have become inactive.

Real Estate Assets

Real estate assets are carried at the appreciated value as of January 19, 2016, the effective date of the change in status to an operating company, less accumulated depreciation from that date. Purchases subsequent to the effective date of the change in status are carried at cost, less accumulated depreciation and impairment losses. Direct and allowable internal costs associated with the development, construction, renovation, and improvement of real estate assets are capitalized. Property taxes and other costs associated with development incurred during the construction period are capitalized. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use.

Acquisition costs are accounted for in accordance with Accounting Standard Update (“ASU”) No. 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business, which was adopted on January 1, 2018

F-9

and are generally capitalized. When stores are acquired, the purchase price is allocated to the tangible and intangible assets acquired and liabilities assumed based on estimated fair values. Allocations to land, building and improvements, and equipment are recorded based upon their respective fair values as estimated by management.

In allocating the purchase price for an acquisition, the Company determines whether the acquisition includes intangible assets or liabilities. The Company allocates a portion of the purchase price to an intangible asset attributed to the value of in-place leases. This intangible is generally amortized to expense over the expected remaining term of the respective leases. Substantially all of the leases in place at acquired stores are at market rates, as the majority of the leases are month-to-month contracts. 

Internal transaction costs associated with acquisitions or dispositions of real estate, as well as repairs and maintenance costs, are charged to expense as incurred. Major replacements and betterments that improve or extend the life of the asset are capitalized and depreciated over their estimated useful lives. Depreciation is computed using the straight-line method over the estimated useful lives of the buildings and improvements, which are generally between 5 and 39 years.

Derivative Financial Instruments

The Company carries all derivative financial instruments on the balance sheet at fair value. Fair value of derivatives is determined by reference to observable prices that are based on inputs not quoted on active markets, but corroborated by market data. The accounting for changes in the fair value of a derivative instrument depends on whether the derivative has been designated and qualifies as part of a hedging relationship. The Company’s use of derivative instruments has been limited to an interest rate cap agreement. The fair values of derivative instruments are included in prepaid expenses and other assets in the accompanying balance sheets. For derivative instruments not designated as cash flow hedges, the unrealized gains and losses are included in interest expense in the accompanying statements of operations. For derivatives designated as cash flow hedges, the effective portion of the changes in the fair value of the derivatives is initially reported in accumulated other comprehensive income (loss) in the Company’s balance sheets and subsequently reclassified into earnings when the hedged transaction affects earnings. The valuation analysis of the interest rate cap reflects the contractual terms of derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves.

Accounts Payable and Accrued Expenses

Accounts payable and accrued expenses primarily consist of property tax accruals, unearned rental income, and trade payables.

Revenue and Expense Recognition

Revenues from stores, which are primarily composed of rental income earned pursuant to month-to-month leases for storage space, as well as associated late charges and administrative fees, are recognized as earned in accordance with ASU Leases-Topic 842. Promotional discounts reduce rental income over the promotional period. Ancillary revenues from sales of merchandise and tenant insurance and other income are recognized when earned.

The Company's management fees are earned subject to the terms of the related property management services agreements (“PSAs”). These PSAs provide that the Company will perform management services, which include leasing and operating the property and providing accounting, marketing, banking, maintenance and other services. These services are provided in exchange for monthly management fees, which are based on a percentage of revenues collected from stores owned by third parties. PSAs generally have original terms of three years, after which management services are provided on a month-to-month basis unless terminated. Management fees are due on the last day of each calendar month that management services are provided.

The Company accounts for the management services provided to a customer as a single performance obligation which are rendered over time each month in accordance with ASU Contracts with Customers-Topic 606. The total amount of consideration from the contract is variable as it is based on monthly revenues, which are influenced by multiple factors, some of which are outside the Company's control. Therefore, the Company recognizes the revenue at the end of each month once the uncertainty is resolved. No disaggregated information relating to PSAs is presented as there is only one contract for the year ended December 31, 2019.

F-10

The Company accrues for property tax expense based upon actual amounts billed and, in some circumstances, estimates and historical trends when bills or assessments have not been received from the taxing authorities or such bills and assessments are in dispute. Cost of operations and general and administrative expense are expensed as incurred.

Credit Risk

Financial assets that are exposed to credit risk consist primarily of cash and cash equivalents and certain portions of accounts receivable including rents receivable from our tenants. Cash and cash equivalents are on deposit with highly rated commercial banks.

Evaluation of Asset Impairment

The Company evaluates its real estate assets, intangible assets consisting of in-place lease, and goodwill for impairment annually. If there are indicators of impairment and we determine that the asset is not recoverable from future undiscounted cash flows to be received through the asset’s remaining life (or, if earlier, the expected disposal date), we record an impairment charge to the extent the carrying amount exceeds the asset’s estimated fair value or net proceeds from expected disposal.

The Company evaluates goodwill for impairment annually and whenever relevant events, circumstances, and other related factors indicate that fair value may be less that carrying amounts. If it is determined that the carrying amount of goodwill exceeds the amount that would be allocated to goodwill if the reporting unit were acquired for estimated fair value, an impairment charge is recorded. There were no indicators of impairment and no impairment charges were recorded during 2019 or 2018.

Stock-based Compensation

The measurement and recognition of compensation expense for all stock-based payment awards to employees are based on estimated fair values. Awards granted are valued at fair value and any compensation expense is recognized over the service periods of each award. For awards granted which contain a graded vesting schedule and the only condition for vesting is a service condition, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For awards granted for which vesting is subject to a performance condition, compensation cost is recognized over the requisite service period if and when the Company concludes it is probable that the performance condition will be achieved.

Loan Procurement Costs

Loan procurement costs, net are presented as a direct deduction from the carrying amount of the related debt liability. If there is not an associated debt liability recorded on the consolidated balance sheets, the costs are recorded as an asset net of accumulated amortization. Loan procurement costs associated with the Company's revolving credit facility remain in Line of credit issuance costs, net of amortization on the Company's consolidated balance sheets. The costs are amortized over the estimated life of the related debt.

Use of Estimates

The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from management’s estimates.

Recently Issued Accounting Standards

In August 2017, the FASB issued ASU No. 2017-12 – Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The standard became effective on January 1, 2020 and is not expected to have a material impact on the Company’s consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13 – Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new guidance changes how entities measure credit losses for most financial assets. This standard requires an entity to estimate its lifetime expected credit loss and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. In November 2018, the FASB issued ASU No. 2018-19 – Codification Improvements to Topic 326, Financial Instruments - Credit Losses, which clarifies that receivables arising from operating leases are within the scope of the leasing standard (ASU No. 2016-02), and not within the scope of ASU No. 2016-13. The standard became effective on January 1, 2020 and is not expected to have a material impact on the Company’s consolidated financial statements.

3. REAL ESTATE ASSETS

The carry value of the Company’s real estate assets is summarized as follows:

	December 31, 2019			December 31, 2018
Land	$	6,122,065		$	5,493,814
Buildings, improvements, and equipment		57,178,338			51,879,327
Construction in progress		1,532,235			94,816
Self storage properties		64,832,638			57,467,957
Less: Accumulated depreciation		(5,080,485	)		(3,656,220	)
Real estate assets, net	$	59,752,153		$	53,811,737

In 2019, the Company broke ground on the Millbrook, NY expansion, which, upon completion in February 2020, added approximately 16,500 of gross square feet of all-climate-controlled units. There is no guarantee that we will experience demand for the newly added expansion or that we will be able to successfully lease-up the expansion to the occupancy level of our other properties. As of December 31, 2019, development costs for this project have been capitalized and are reflected in real estate assets, net on the Company’s consolidated balance sheets.  Construction of the expansion was completed in the first quarter of 2020.

4. ACQUISITIONS

In November 2019 the Company acquired a self storage property. The acquisition of the property was accounted for as an asset acquisition. The cost of the property, including closing costs, was assigned to land, buildings, equipment, and in-place customer leases based on their relative fair values.

The purchase price of the property acquired in 2019 has been assigned as follows:

					Consideration Paid					Acquisition Date Fair Value
							Net Other
							Liabilities
							Assumed							In-Place		Closing
	Number of	Date of	Purchase				(Assets					Building and		Customer		Costs
State	Properties	Acquisition	Price		Cash Paid		Acquired)			Land		Equipment		Leases		Expensed
NY	1	11/19/2019	$	6,282,514	$	6,287,082	$	(4,568	)	$	628,251	$	5,240,825	$	413,438	$	—
Total			$	6,282,514	$	6,287,082	$	(4,568	)	$	628,251	$	5,240,825	$	413,438	$	—

F-12

The Company measures the fair value of in-place customer lease intangible assets based on the Company’s experience with customer turnover and the estimated cost to replace the in-place leases. The Company amortizes in-place customer leases on a straight-line basis over 12 months (the estimated future benefit period). Amortization expense related to in-place customer leases was $14,643 and $0 for the years ended December 31, 2019 and 2018, respectively.

The following table summarizes the Company’s revenue and earnings associated with the 2019 acquisition from the acquisition date, that are included in the consolidated statements of operations for the year ended December 31, 2019:

	Year Ended
	December 31, 2019
Total revenue	$	60,244
Net loss		(7,484	)

5. MARKETABLE EQUITY SECURITIES

Investments in marketable equity securities consisted of the following:

			Gross Unrealized
December 31, 2019	Cost Basis		Gains		Losses		Value
Investment in marketable equity securities
Common stocks	$	755,487	$	1,005,825	$	—	$	1,761,312

Total investment in marketable equity securities	$	755,487	$	812,120	$	—	$	1,567,607

6. FAIR VALUE MEASUREMENTS

The use of fair value to measure the financial instruments held by the Company and its subsidiaries is fundamental to its consolidated financial statements and is a critical accounting estimate because a substantial portion of its assets and liabilities are recorded at estimated fair value. The application of fair value measurements may be on a recurring or nonrecurring basis depending on the accounting principles applicable to the specific asset or liability or whether management has elected to carry the item at its estimated fair value.

The hierarchy of valuation techniques is based on whether the inputs to those techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1 — Quoted prices in active markets for identical instruments or liabilities.

Level 2 — Prices determined using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing an asset or liability and are developed based on market data obtained from sources independent of the Company. These may include quoted prices for similar assets and liabilities, interest rates, prepayment speeds, credit risk, and market-corroborated inputs.

Level 3 — Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Company’s own assumptions about the factors that market participants use in pricing an asset or liability and are based on the best information available in the circumstances.

F-13

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when estimating fair value. The valuation method used to estimate fair value may produce a fair value measurement that may not be indicative of ultimate realizable value. Furthermore, while management believes its valuation methods are appropriate and consistent with those used by other market participants, the use of different methods or assumptions to estimate the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Those estimated values may differ significantly from the values that would have been used had a readily available market for such loans or investments existed, or had such loans or investments been liquidated, and those differences could be material to the financial statements.

Fair valued assets consist of shares of equity securities and an interest rate cap. The value of the equity securities is based on a traded market price and is considered to be a level 1 measurement, and the value of the interest rate cap is based on its maturity, observable market-based inputs including interest rate curves and is considered to be a level 2 measurement.

The following table provides the assets and liabilities carried at fair value measured on a recurring basis as of December 31, 2019 and December 31, 2018:

December 31, 2019	Level 1		Level 2		Level 3		Total
Assets
Marketable equity securities	$	1,761,312	$	—	$	—	$	1,761,312
Interest rate cap	—			51	—			51
Total assets at fair value	$	1,761,312	$	51	$	—	$	1,761,363
December 31, 2018	Level 1		Level 2		Level 3		Total
Assets
Marketable equity securities	$	1,567,607	$	—	$	—	$	1,567,607
Interest rate cap	—			4,889	—			4,889
Total assets at fair value	$	1,567,607	$	4,889	$	—	$	1,572,496

There were no assets transferred from level 1 to level 2 as of December 31, 2019 or December 31, 2018. The Company did not have any assets or liabilities that are re-measured on a recurring basis using significant unobservable inputs as of December 31, 2019 or December 31, 2018.

The fair values of financial instruments including cash and cash equivalents, restricted cash, accounts receivable, and accounts payable approximated their respective carrying values as of December 31, 2019 and 2018. The aggregate estimated fair value of the Company’s debt was $24,474,174 and $18,877,333 as of December 31, 2019 and 2018, respectively.  These estimates were based on market interest rates for comparable obligations, general market conditions and maturity. The Company’s debt is classified as level 2 in the fair value hierarchy.

7.DERIVATIVES

The Company’s objective in using an interest rate derivative is to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company uses an interest rate cap to manage interest rate risk. The Company carries the premium paid for the interest rate cap as an asset on the balance sheet at fair value. The change in the unrealized gain or loss of the premium is recorded as an increase or decrease to interest expense.

The following table summarizes the terms of the Company’s derivative financial instrument as of December 31, 2019:

	Notional Amount					Effective	Maturity
Product	December 31, 2019		December 31, 2018		Strike	Date	Date
Cap Agreement	$	7,500,000	$	7,500,000	3.50 % - 4.00%	12/24/2018	12/20/2021

8. NOTE PAYABLE AND REVOLVING LINE OF CREDIT

Note Payable

On June 24, 2016, certain wholly owned subsidiaries (the “Secured Subsidiaries”) of the Company entered into a loan agreement (the “Loan Agreement”) borrowing the principal amount of $20 million pursuant to a promissory note (the “Promissory Note”). The Promissory Note bears an interest rate equal to 4.192% per annum and is due to mature on July 1, 2036. Pursuant to a security agreement (the “Security Agreement”), the obligations under the Loan Agreement are secured by certain real estate assets owned by the Secured Subsidiaries.

The Company entered into a non-recourse guaranty on June 24, 2016 (the “Guaranty,” and together with the Loan Agreement, the Promissory Note and the Security Agreement, the “Loan Documents”) to guarantee the payment to Lender of certain obligations of the Secured Subsidiaries under the Loan Agreement.

The Loan Documents require the Secured Subsidiaries and the Company to comply with certain covenants, including, among others, a minimum net worth test and other customary covenants. The Lender may accelerate amounts outstanding under the Loan Documents upon the occurrence of an Event of Default (as defined in the Loan Agreement) including, but not limited to, the failure to pay amounts due or commencement of bankruptcy proceedings. As of December 31, 2019 and 2018, the Company was in compliance with these covenants.

The Company incurred loan procurement costs of $646,246 and such costs have been recorded net of the note payable on the consolidated balance sheets. The costs are amortized over the term of the loan using the effective interest method and are recorded as an adjustment to interest expense. The Company recorded amortization expense of $41,492 and $42,333 for the years ended December 31, 2019 and 2018, respectively.

As of December 31, 2019 and 2018 the carrying value of the Company’s note payable is summarized as follows:

Note Payable	December 31, 2019			December 31, 2018
Principal balance outstanding	$	19,338,556		$	19,809,511
Less: Loan procurement costs, net		(498,769	)		(540,261	)
Total note payable, net	$	18,839,787		$	19,269,250

As of December 31, 2019, the note payable was secured by certain of its self storage properties with an aggregate net book value of approximately $34.6 million. The note payable paid interest only from August 1, 2016 through June 30, 2018. The following table represents the future principal payment requirements on the note payable as of December 31, 2019:

2020	$	492,797
2021		513,857
2022		535,816
2023		558,714
2024		582,591
2025 and thereafter		16,654,781
Total principal payments	$	19,338,556

Revolving Line of Credit

On December 20, 2018, certain wholly owned subsidiaries (the “Subsidiaries”) of the Company entered into a revolving credit loan agreement (the “Agreement”) between the Subsidiaries and TCF National Bank (the “Lender”). Under the Agreement, the Subsidiaries are borrowing from the Lender in the principal amount of up to

F-15

$10 million pursuant to a promissory note (the “Note”). The Note bears an interest rate equal to 3.00% over the One Month U.S. Dollar London Inter-Bank Offered Rate and is due to mature on December 20, 2021. The obligations under the Agreement are secured by certain real estate assets owned by the Subsidiaries.

The Company entered into a guaranty of payment on December 20, 2018 (the “Guaranty,” and together with the Agreement, the Note and related instruments, the “Revolver”) to guarantee the payment to Lender of certain obligations of the Subsidiaries under the Agreement.

The Revolver requires the Subsidiaries and the Company to comply with certain covenants, including, among others, customary financial covenants. The Lender may accelerate amounts outstanding under the Loan Documents upon the occurrence of an Event of Default (as defined in the Agreement) including, but not limited to, the failure to pay amounts due to the Lender or commencement of bankruptcy proceedings.

The Company incurred issuance costs of $477,981 and such costs are amortized as an adjustment to interest expense over the term of the loan. The Company recorded amortization expense of $159,327 and $6,785 for the years ended December 31, 2019 and 2018, respectively. The outstanding loan balance under the Revolver was $4,914,000 and $0 as of December 31, 2019 and 2018, respectively.

9. LEASES

Global Self Storage as Lessor

The Company's property rental revenue is primarily related to rents received from tenants at its operating stores. The Company's leases with its self storage tenants are generally on month-to-month terms, include automatic monthly renewals, allow flexibility to increase rental rates over time as market conditions permit, and provide for the collection of contingent fees such as late fees. These leases do not include any terms or conditions that allow the tenants to purchase the leased space. All self-storage leases for which the Company acts as lessor have been classified as operating leases. The real estate assets related to the Company's stores are included in "Real estate assets, net" on the Company's consolidated balance sheets and are presented at historical cost less accumulated depreciation and impairment, if any. Rental income related to these operating leases is included in Property rental revenue on the Company's consolidated statements of operations, and is recognized each month during the month-to-month terms at the rental rate in place during each month.

Global Self Storage as Lessee

The Company is a lessee in a lease agreement for an automobile entered into November 2019 with a lease term of 3 years. The lease agreement does not contain any material residual value guarantees or material restrictive covenants. As a result of the Company’s election of the package of practical expedients permitted within ASC 842, which among other things, allows for the carryforward of historical lease classification, all of the Company’s lease agreements have been classified as operating leases. Lease expense for payments related to the Company’s operating leases is recognized on a straight-line basis over the lease term.

Right-of-use assets represent the Company’s right to use an underlying asset during the lease term and lease liabilities represent the Company’s obligation to make lease payments as specified in the lease. Right-of-use assets and lease liabilities related to the Company’s operating leases are recognized at the lease commencement date based on the present value of the remaining lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available surrounding the Company’s secured borrowing rates and implied secured spread at the lease commencement date in determining the present value of lease payments. The right-of-use asset also includes any lease payments made at or before lease commencement less any lease incentives. Upon adoption of ASC 842 on January 1, 2019, the Company had no right-of-use assets and lease liabilities related to its operating leases. As of December 31, 2019, the Company had right-of-use assets and lease liabilities related to its operating leases of $37,700 and $37,700, which are included in Other assets, net and Accounts payable, accrued expenses and other liabilities on the Company’s consolidated balance sheets, respectively. As of December 31, 2019, the Company’s weighted average remaining lease term and weighted average discount rate related to its operating leases were approximately 3 years and 4.78%, respectively.

F-16

The future minimum lease payments under the automobile lease are $14,254, $14,254, and $11,878 for the years ending December 31, 2020, 2021, and 2022, respectively.

10. EARNINGS PER SHARE

Basic earnings per share is computed using the weighted average number of shares outstanding. Diluted earnings per share is computed using the weighted average number of shares outstanding adjusted for the incremental shares attributed to potentially diluted securities. The following table sets forth the computation of basic and diluted earnings per share:

	For the Year Ended December 31,
	2019		2018
Net income	$	590,619	$	619,448
Weighted average common shares outstanding:
Average number of common shares outstanding - basic		7,699,966		7,622,287
Net effect of dilutive unvested restricted stock awards included for treasury stock method		2,151		1,835
Average number of common shares outstanding - diluted		7,702,117		7,624,122
Earnings per common share
Basic	$	0.08	$	0.08
Diluted	$	0.08	$	0.08

Common stock dividends paid in cash totaled $2,107,376 ($0.26 per share) and $1,992,397 ($0.26 per share) for the years ended December 31, 2019 and 2018, respectively.

11. RELATED PARTY TRANSACTIONS

Certain officers and directors of the Company also serve as officers and directors of Winmill & Co. Incorporated (“Winco”), Bexil, Tuxis, and their affiliates (collectively with the Company, the “Affiliates”). As of December 31, 2019, certain of the Affiliates owned approximately 5% of the Company’s outstanding common stock. Pursuant to an arrangement between a professional employer organization (“PEO”) and the Affiliates, the PEO provides payroll, benefits, compliance, and related services for employees of the Affiliates in accordance with applicable rules and regulations under the IRC and, in connection therewith, Midas Management Corporation (“MMC”), a subsidiary of Winco, acts as a conduit payer of compensation and benefits to the Affiliates’ employees including those who are concurrently employed by the Company and its Affiliates. Rent expense of concurrently used office space and overhead expenses for various concurrently used administrative and support functions incurred by the Affiliates are allocated at cost among them. The Affiliates participate in a 401(k) retirement savings plan for substantially all qualified employees. A matching expense based upon a percentage of contributions to the plan by eligible employees is incurred and allocated among the Affiliates. The matching expense is accrued and funded on a current basis and may not exceed the amount permitted as a deductible expense under the IRC. The aggregate rent and overhead accrued and paid by the Company to Winco for the years ended December 31, 2019 and 2018 was $77,850 and $53,969, respectively. The Company had reimbursements payable to MMC and Winco for compensation and benefits and rent and overhead of $19,096 and $20,885 as of December 31, 2019 and 2018, respectively.

F-17

The Company currently reimburses monthly automobile expenses of $1,000 per month to its President, Mark C. Winmill. To the extent that the monthly payment under the Company’s automobile lease exceeds the current monthly reimbursement amount, Mr. Winmill voluntarily reimburses the Company for the excess amount. In this regard, Mr. Winmill has reimbursed the Company $3,228 and $3,228 for the years ended December 31, 2019 and 2018, respectively.

The Company leases office space and storage to certain Affiliates under a rental agreement. The terms of occupancy are month to month and automatically renew unless terminated by either party on ten days’ written notice. The Company earned rental income of $9,204 and $9,204 for the years ended December 31, 2019 and 2018, respectively.

In December 2019, the Company paid Tuxis $900,000 in connection with the purchase of a property made in 2016.

12. CAPITAL STOCK

As of December 31, 2019, the Company was authorized to issue 450,000,000 shares of $0.01 par value common stock of which 9,330,297 had been issued and was outstanding. The Company was also authorized to issue 50,000,000 shares of preferred stock, $0.01 par value, authorized, of which none has been issued.  

On November 18, 2019, the Company commenced a rights offering to eligible common stockholders of the Company for the purchase of up to approximately $11.6 million of newly issued shares of the Company’s common stock. The rights offering concluded on December 13, 2019, with the Company raising $6,280,987, net of offering costs, from the sale of 1,601,291 shares at $4.18 per share.

13. STOCK-BASED COMPENSATION

On October 16, 2017 (“Effective Date”), the Company’s stockholders approved the Company’s 2017 Equity Incentive Plan (the “Plan”). The Plan is designed to provide equity-based incentives to certain eligible persons, as defined in the Plan, in the form of options, share appreciation rights, restricted stock, restricted stock units, dividend equivalent rights or other forms of equity-based compensation as determined in the discretion of the Board of Directors, the Compensation Committee of the Board of Directors, or other designee thereof. The total number of shares of common stock reserved and available for issuance under the Plan on the Effective Date was 760,000.

The Company approved restricted stock awards under the Plan to certain of its officers and employees during 2019 in the aggregate amount of 28,755 shares, of which 13,730 shares are time-based grants and 15,025 shares are performance-based grants. During 2018, the Company approved restricted stock awards under the Plan of 73,155 shares, of which 58,130 shares are time-based grants and 15,025 shares are performance-based grants. The Company recorded $102,990 and $80,771 of expense in general and administrative expense in its statement of operations related to restricted stock awards for the years ended December 31, 2019 and 2018, respectively. At December 31, 2019, there was $171,556 and $116,464 of unrecognized compensation expense related to unvested time-based and performance-based restricted stock awards, respectively. That cost is expected to be recognized over a weighted—average period of 2.44 years and 2.66 years for time-based and performance-based awards, respectively. The fair value of common stock awards is determined based on the closing trading price of the Company’s common stock on the grant date.

Time-Based Restricted Stock Grants

These time-based grants vest solely based on continued employment, with 6.25% of the shares eligible to vest on each three-month anniversary of the grant date during the four-year vesting period. Time-based restricted stock cannot be transferred during the vesting period. Grants of time-based restricted stock entitle the holder to dividends paid by the Company on shares of its common stock.

A summary of the Company’s time-based restricted stock grant activity is as follows:

F-18

				Weighted-Average
				Grant-Date
Time-Based Restricted Stock Grants	Stock			Fair Value
Unvested at December 31, 2018		47,228		$	4.42
Granted		13,730		$	3.94
Vested		(16,065	)	$	4.36
Forfeited		(4,961	)	$	4.15
Unvested at December 31, 2019		39,932		$	4.31

Performance-Based Restricted Stock Grants

Performance-based restricted stock grants vest based on continued employment and the achievement of certain Funds from Operations, as adjusted (“AFFO”) and same store revenue growth (“SSRG”) goals by the Company during 2019. Between 0% and 200% of these shares will be earned based on achievement of the AFFO and SSRG goals in 2019, and the shares which are earned will remain subject to quarterly vesting during the remaining four-year time vesting period. Dividends paid by the Company prior to the determination of how many shares are earned will be retained by the Company and released only with respect to earned shares. If a Change in Control (as defined in the Plan) occurs during 2019, the number of shares earned will equal the greater of the number of shares granted and the number of shares which would have been earned based on the AFFO and SSRG through the date of the Change in Control. If following a Change in Control, a grantee is terminated by the Company without Cause or by the grantee with Good Reason (as each is defined in the Plan), all unvested restricted stock will fully vest. Performance-based restricted stock earned during 2019 and 2018 were 15,025 shares and 27,613 shares, respectively.

A summary of the Company’s performance-based restricted stock grant activity is as follows:

				Weighted-Average
				Grant-Date
Performance-based Stock Grants	Stock			Fair Value
Unvested at December 31, 2018		15,025		$	4.42
Granted		27,613		$	4.16
Vested		(14,899	)	$	4.33
Unvested at December 31, 2019		27,739		$	4.21

Forfeitures are accounted for as they occur, compensation cost previously recognized for an award that is forfeited because of a failure to satisfy a service or performance condition is reversed in the period of the forfeiture.

14. COMMITMENTS AND CONTINGENCIES

The Company enters into contracts that contain a variety of representations and warranties and which may provide general indemnifications. The Company’s maximum exposure under these arrangements is unknown as it involves future claims that may be made against the Company under circumstances that have not occurred.

15. SUBSEQUENT EVENTS

On March 26, 2020, the Company approved restricted share awards under the Plan to certain of its officers and employees in the aggregate amount of 28,755 shares, of which 15,025 shares are performance-based grants and the remainder of the shares are time-based grants. Between 0% and 200% of these shares will be earned based on achievement of the AFFO and SSRG goals in 2020, and the shares which are earned will remain subject to quarterly vesting during the remaining four-year time vesting period. Dividends paid by the Company prior to the

F-19

determination of how many shares are earned will be retained by the Company and released only with respect to earned shares. If a Change in Control (as defined in the Plan) occurs during 2020, the number of shares earned will equal the greater of the number of shares granted and the number of shares which would have been earned based on the AFFO and SSRG through the date of the Change in Control. If following a Change in Control, a grantee is terminated by the Company without Cause or by the grantee with Good Reason (as each is defined in the Plan), all unvested restricted shares will fully vest.

On March 2, 2020, the Company declared a cash dividend of $0.065 per common share payable on March 31, 2020 to stockholders of record as of March 16, 2020.

On March 11, 2020, the World Health Organization declared the novel coronavirus (“COVID-19”) as a pandemic, and on March 13, 2020 the United States declared a national emergency with respect to COVID-19. The outbreak of COVID-19 has severely impacted global economic activity and caused significant volatility and negative pressure in financial markets. The global impact of the outbreak has been rapidly evolving and many countries, including the United States, have reacted by instituting quarantines, mandating business and school closures and restricting travel. Such actions are creating disruption in global supply chains, and adversely impacting a number of industries, such as transportation, hospitality and entertainment. The outbreak could have a continued adverse impact on economic and market conditions and trigger a period of global economic slowdown. The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19. Nevertheless, COVID-19 presents material uncertainty and risk with respect to the to the Company's business, financial condition, results of operations and cash flows, such as the potential negative impact to occupancy at its properties, financing arrangements, increased costs of operations, changes in law and/or regulation, and uncertainty regarding government and regulatory policy. Accordingly, the Company cannot predict the extent to which its financial condition and results of operations will be affected at this time.

Summary of Significant Accounting Policies

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Upon deregistration as an investment company, effective January 19, 2016, the Company’s status changed to an operating company from an investment company since it no longer met the assessment of an investment company under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946 (“ASC 946”). The Company discontinued applying the guidance in ASC 946 and began to account for the change in status prospectively by accounting for its investments in accordance with other U.S. generally accepted accounting principles (“GAAP”) topics as of the date of the change in status.

The consolidated financial statements of the Company are presented on the accrual basis of accounting in accordance with GAAP and include the accounts of the Company and its wholly owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.

Reclassifications

Certain amounts from the prior year have been reclassified to conform to current year presentation as described below.

Accounting Standards Adopted

In February 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-02 - Leases (Topic 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either financing or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification determines whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less are accounted for similar to previous guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to previous guidance for sales-type leases, direct financing leases and operating leases. The Company adopted the standard on January 1, 2019, the date it became effective for public companies, using the modified retrospective approach whereby the cumulative effect of adoption was recognized on the adoption date and prior periods were not restated. There was no net cumulative effect adjustment to retained earnings as of January 1, 2019 as a result of this adoption. Upon adoption, the Company elected the package of practical expedients permitted within the standard, which among other things, allows for the carryforward of historical lease classification. The Company also elected the practical expedient provided to lessors in a subsequent amendment to the standard that removed the requirement to separate lease and nonlease components, provided certain conditions were met. Refer to note 9 for the impact of the adoption of ASU No. 2016-02 – Leases (Topic 842) on the Company’s consolidated financial statements.

Cash, Cash Equivalents, and Restricted Cash

The Company’s cash is deposited with financial institutions located throughout the United States and at times may exceed federally insured limits. The Company considers all highly liquid investments, which may include money market fund shares, with a maturity of three months or less to be cash equivalents. Restricted cash is comprised of escrowed funds deposited with a bank relating to capital expenditures.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash in our consolidated balance sheets to the total amount shown in our consolidated statements of cash flows:

	December 31, 2019		December 31, 2018
Cash and cash equivalents	$	3,990,160	$	1,526,203
Restricted cash		263,405		186,063
Total cash, cash equivalents, and restricted cash as shown in our consolidated statements of cash flows	$	4,253,565	$	1,712,266

Income Taxes

The Company has elected to be treated as a REIT under the IRC. In order to maintain its qualification as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax with respect to that portion of its income which meets certain criteria and is distributed annually to stockholders. The Company plans to continue to operate so that it meets the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. If the Company were to fail to meet these requirements, it would be subject to federal income tax. In managements opinion, the requirements to maintain these elections are being met. The Company is subject to certain state and local taxes.

The Company has elected to treat its corporate subsidiary, SSG TRS LLC, as a taxable REIT subsidiary (“TRS”). In general, the Company’s TRS may perform additional services for tenants and may engage in any real estate or non-real estate related business. A TRS is subject to federal corporate income tax.

The Company recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. The Company has reviewed its tax positions and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on federal, state, and local income tax returns for open tax years (2016 – 2018), or is expected to be taken in the Company’s 2019 tax returns.

Marketable Equity Securities

Investments in equity securities that have readily determinable fair values are accounted for equity securities measured at fair value. Gains or losses from changes in the fair value of equity securities are recorded in net income, until the investment is sold or otherwise disposed. The specific identification method is used to determine the realized gain or loss on investments sold or otherwise disposed.

Fair value is determined using a valuation hierarchy generally by reference to an active trading market, using quoted closing or bid prices. Judgment is used to ascertain if a formerly active market has become inactive and in determining fair values when markets have become inactive.

Real Estate Assets

Real estate assets are carried at the appreciated value as of January 19, 2016, the effective date of the change in status to an operating company, less accumulated depreciation from that date. Purchases subsequent to the effective date of the change in status are carried at cost, less accumulated depreciation and impairment losses. Direct and allowable internal costs associated with the development, construction, renovation, and improvement of real estate assets are capitalized. Property taxes and other costs associated with development incurred during the construction period are capitalized. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use.

Acquisition costs are accounted for in accordance with Accounting Standard Update (“ASU”) No. 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business, which was adopted on January 1, 2018 and are generally capitalized. When stores are acquired, the purchase price is allocated to the tangible and intangible assets acquired and liabilities assumed based on estimated fair values. Allocations to land, building and improvements, and equipment are recorded based upon their respective fair values as estimated by management.

In allocating the purchase price for an acquisition, the Company determines whether the acquisition includes intangible assets or liabilities. The Company allocates a portion of the purchase price to an intangible asset attributed to the value of in-place leases. This intangible is generally amortized to expense over the expected remaining term of the respective leases. Substantially all of the leases in place at acquired stores are at market rates, as the majority of the leases are month-to-month contracts. 

Internal transaction costs associated with acquisitions or dispositions of real estate, as well as repairs and maintenance costs, are charged to expense as incurred. Major replacements and betterments that improve or extend the life of the asset are capitalized and depreciated over their estimated useful lives. Depreciation is computed using the straight-line method over the estimated useful lives of the buildings and improvements, which are generally between 5 and 39 years.

Derivative Financial Instruments

The Company carries all derivative financial instruments on the balance sheet at fair value. Fair value of derivatives is determined by reference to observable prices that are based on inputs not quoted on active markets, but corroborated by market data. The accounting for changes in the fair value of a derivative instrument depends on whether the derivative has been designated and qualifies as part of a hedging relationship. The Company’s use of derivative instruments has been limited to an interest rate cap agreement. The fair values of derivative instruments are included in prepaid expenses and other assets in the accompanying balance sheets. For derivative instruments not designated as cash flow hedges, the unrealized gains and losses are included in interest expense in the accompanying statements of operations. For derivatives designated as cash flow hedges, the effective portion of the changes in the fair value of the derivatives is initially reported in accumulated other comprehensive income (loss) in the Company’s balance sheets and subsequently reclassified into earnings when the hedged transaction affects earnings. The valuation analysis of the interest rate cap reflects the contractual terms of derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves.

Accounts Payable and Accrued Expenses

Accounts payable and accrued expenses primarily consist of property tax accruals, unearned rental income, and trade payables.

Revenue and Expense Recognition

Revenues from stores, which are primarily composed of rental income earned pursuant to month-to-month leases for storage space, as well as associated late charges and administrative fees, are recognized as earned in accordance with ASU Leases-Topic 842. Promotional discounts reduce rental income over the promotional period. Ancillary revenues from sales of merchandise and tenant insurance and other income are recognized when earned.

The Company's management fees are earned subject to the terms of the related property management services agreements (“PSAs”). These PSAs provide that the Company will perform management services, which include leasing and operating the property and providing accounting, marketing, banking, maintenance and other services. These services are provided in exchange for monthly management fees, which are based on a percentage of revenues collected from stores owned by third parties. PSAs generally have original terms of three years, after which management services are provided on a month-to-month basis unless terminated. Management fees are due on the last day of each calendar month that management services are provided.

The Company accounts for the management services provided to a customer as a single performance obligation which are rendered over time each month in accordance with ASU Contracts with Customers-Topic 606. The total amount of consideration from the contract is variable as it is based on monthly revenues, which are influenced by multiple factors, some of which are outside the Company's control. Therefore, the Company recognizes the revenue at the end of each month once the uncertainty is resolved. No disaggregated information relating to PSAs is presented as there is only one contract for the year ended December 31, 2019.

The Company accrues for property tax expense based upon actual amounts billed and, in some circumstances, estimates and historical trends when bills or assessments have not been received from the taxing authorities or such bills and assessments are in dispute. Cost of operations and general and administrative expense are expensed as incurred.

Credit Risk

Financial assets that are exposed to credit risk consist primarily of cash and cash equivalents and certain portions of accounts receivable including rents receivable from our tenants. Cash and cash equivalents are on deposit with highly rated commercial banks.

Evaluation of Asset Impairment

The Company evaluates its real estate assets, intangible assets consisting of in-place lease, and goodwill for impairment annually. If there are indicators of impairment and we determine that the asset is not recoverable from future undiscounted cash flows to be received through the asset’s remaining life (or, if earlier, the expected disposal date), we record an impairment charge to the extent the carrying amount exceeds the asset’s estimated fair value or net proceeds from expected disposal.

The Company evaluates goodwill for impairment annually and whenever relevant events, circumstances, and other related factors indicate that fair value may be less that carrying amounts. If it is determined that the carrying amount of goodwill exceeds the amount that would be allocated to goodwill if the reporting unit were acquired for estimated fair value, an impairment charge is recorded. There were no indicators of impairment and no impairment charges were recorded during 2019 or 2018.

Stock-based Compensation

The measurement and recognition of compensation expense for all stock-based payment awards to employees are based on estimated fair values. Awards granted are valued at fair value and any compensation expense is recognized over the service periods of each award. For awards granted which contain a graded vesting schedule and the only condition for vesting is a service condition, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For awards granted for which vesting is subject to a performance condition, compensation cost is recognized over the requisite service period if and when the Company concludes it is probable that the performance condition will be achieved.

Loan Procurement Costs

Loan procurement costs, net are presented as a direct deduction from the carrying amount of the related debt liability. If there is not an associated debt liability recorded on the consolidated balance sheets, the costs are recorded as an asset net of accumulated amortization. Loan procurement costs associated with the Company's revolving credit facility remain in Line of credit issuance costs, net of amortization on the Company's consolidated balance sheets. The costs are amortized over the estimated life of the related debt.

Use of Estimates

The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from management’s estimates.

Recently Issued Accounting Standards

In August 2017, the FASB issued ASU No. 2017-12 – Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The standard became effective on January 1, 2020 and is not expected to have a material impact on the Company’s consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13 – Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new guidance changes how entities measure credit losses for most financial assets. This standard requires an entity to estimate its lifetime expected credit loss and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. In November 2018, the FASB issued ASU No. 2018-19 – Codification Improvements to Topic 326, Financial Instruments - Credit Losses, which clarifies that receivables arising from operating leases are within the scope of the leasing standard (ASU No. 2016-02), and not within the scope of ASU No. 2016-13. The standard became effective on January 1, 2020 and is not expected to have a material impact on the Company’s consolidated financial statements.

In 2019, the Company broke ground on the Millbrook, NY expansion, which, upon completion in February 2020, added approximately 16,500 of gross square feet of all-climate-controlled units. There is no guarantee that we will experience demand for the newly added expansion or that we will be able to successfully lease-up the expansion to the occupancy level of our other properties. As of December 31, 2019, development costs for this project have been capitalized and are reflected in real estate assets, net on the Company’s consolidated balance sheets.  Construction of the expansion was completed in the first quarter of 2020.

Acquisitions

4. ACQUISITIONS

In November 2019 the Company acquired a self storage property. The acquisition of the property was accounted for as an asset acquisition. The cost of the property, including closing costs, was assigned to land, buildings, equipment, and in-place customer leases based on their relative fair values.

The purchase price of the property acquired in 2019 has been assigned as follows:

					Consideration Paid					Acquisition Date Fair Value
							Net Other
							Liabilities
							Assumed							In-Place		Closing
	Number of	Date of	Purchase				(Assets					Building and		Customer		Costs
State	Properties	Acquisition	Price		Cash Paid		Acquired)			Land		Equipment		Leases		Expensed

The Company measures the fair value of in-place customer lease intangible assets based on the Company’s experience with customer turnover and the estimated cost to replace the in-place leases. The Company amortizes in-place customer leases on a straight-line basis over 12 months (the estimated future benefit period). Amortization expense related to in-place customer leases was $14,643 and $0 for the years ended December 31, 2019 and 2018, respectively.

The following table summarizes the Company’s revenue and earnings associated with the 2019 acquisition from the acquisition date, that are included in the consolidated statements of operations for the year ended December 31, 2019:

Fair Value Measurements

6. FAIR VALUE MEASUREMENTS

The use of fair value to measure the financial instruments held by the Company and its subsidiaries is fundamental to its consolidated financial statements and is a critical accounting estimate because a substantial portion of its assets and liabilities are recorded at estimated fair value. The application of fair value measurements may be on a recurring or nonrecurring basis depending on the accounting principles applicable to the specific asset or liability or whether management has elected to carry the item at its estimated fair value.

The hierarchy of valuation techniques is based on whether the inputs to those techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1 — Quoted prices in active markets for identical instruments or liabilities.

Level 2 — Prices determined using other significant observable inputs. Observable inputs are inputs that other market participants would use in pricing an asset or liability and are developed based on market data obtained from sources independent of the Company. These may include quoted prices for similar assets and liabilities, interest rates, prepayment speeds, credit risk, and market-corroborated inputs.

Level 3 — Prices determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect the Company’s own assumptions about the factors that market participants use in pricing an asset or liability and are based on the best information available in the circumstances.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when estimating fair value. The valuation method used to estimate fair value may produce a fair value measurement that may not be indicative of ultimate realizable value. Furthermore, while management believes its valuation methods are appropriate and consistent with those used by other market participants, the use of different methods or assumptions to estimate the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Those estimated values may differ significantly from the values that would have been used had a readily available market for such loans or investments existed, or had such loans or investments been liquidated, and those differences could be material to the financial statements.

Fair valued assets consist of shares of equity securities and an interest rate cap. The value of the equity securities is based on a traded market price and is considered to be a level 1 measurement, and the value of the interest rate cap is based on its maturity, observable market-based inputs including interest rate curves and is considered to be a level 2 measurement.

The following table provides the assets and liabilities carried at fair value measured on a recurring basis as of December 31, 2019 and December 31, 2018:

December 31, 2019	Level 1		Level 2		Level 3		Total
Assets
Marketable equity securities	$	1,761,312	$	—	$	—	$	1,761,312
Interest rate cap	—			51	—			51
Total assets at fair value	$	1,761,312	$	51	$	—	$	1,761,363
December 31, 2018	Level 1		Level 2		Level 3		Total
Assets
Marketable equity securities	$	1,567,607	$	—	$	—	$	1,567,607
Interest rate cap	—			4,889	—			4,889
Total assets at fair value	$	1,567,607	$	4,889	$	—	$	1,572,496

There were no assets transferred from level 1 to level 2 as of December 31, 2019 or December 31, 2018. The Company did not have any assets or liabilities that are re-measured on a recurring basis using significant unobservable inputs as of December 31, 2019 or December 31, 2018.

The fair values of financial instruments including cash and cash equivalents, restricted cash, accounts receivable, and accounts payable approximated their respective carrying values as of December 31, 2019 and 2018. The aggregate estimated fair value of the Company’s debt was $24,474,174 and $18,877,333 as of December 31, 2019 and 2018, respectively.  These estimates were based on market interest rates for comparable obligations, general market conditions and maturity. The Company’s debt is classified as level 2 in the fair value hierarchy.

7.DERIVATIVES

The Company’s objective in using an interest rate derivative is to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company uses an interest rate cap to manage interest rate risk. The Company carries the premium paid for the interest rate cap as an asset on the balance sheet at fair value. The change in the unrealized gain or loss of the premium is recorded as an increase or decrease to interest expense.

The following table summarizes the terms of the Company’s derivative financial instrument as of December 31, 2019:

Note Payable and Revolving Line of Credit

8. NOTE PAYABLE AND REVOLVING LINE OF CREDIT

Note Payable

On June 24, 2016, certain wholly owned subsidiaries (the “Secured Subsidiaries”) of the Company entered into a loan agreement (the “Loan Agreement”) borrowing the principal amount of $20 million pursuant to a promissory note (the “Promissory Note”). The Promissory Note bears an interest rate equal to 4.192% per annum and is due to mature on July 1, 2036. Pursuant to a security agreement (the “Security Agreement”), the obligations under the Loan Agreement are secured by certain real estate assets owned by the Secured Subsidiaries.

The Company entered into a non-recourse guaranty on June 24, 2016 (the “Guaranty,” and together with the Loan Agreement, the Promissory Note and the Security Agreement, the “Loan Documents”) to guarantee the payment to Lender of certain obligations of the Secured Subsidiaries under the Loan Agreement.

The Loan Documents require the Secured Subsidiaries and the Company to comply with certain covenants, including, among others, a minimum net worth test and other customary covenants. The Lender may accelerate amounts outstanding under the Loan Documents upon the occurrence of an Event of Default (as defined in the Loan Agreement) including, but not limited to, the failure to pay amounts due or commencement of bankruptcy proceedings. As of December 31, 2019 and 2018, the Company was in compliance with these covenants.

The Company incurred loan procurement costs of $646,246 and such costs have been recorded net of the note payable on the consolidated balance sheets. The costs are amortized over the term of the loan using the effective interest method and are recorded as an adjustment to interest expense. The Company recorded amortization expense of $41,492 and $42,333 for the years ended December 31, 2019 and 2018, respectively.

As of December 31, 2019 and 2018 the carrying value of the Company’s note payable is summarized as follows:

Note Payable	December 31, 2019			December 31, 2018
Principal balance outstanding	$	19,338,556		$	19,809,511
Less: Loan procurement costs, net		(498,769	)		(540,261	)
Total note payable, net	$	18,839,787		$	19,269,250

As of December 31, 2019, the note payable was secured by certain of its self storage properties with an aggregate net book value of approximately $34.6 million. The note payable paid interest only from August 1, 2016 through June 30, 2018. The following table represents the future principal payment requirements on the note payable as of December 31, 2019:

2020	$	492,797

Total principal payments	$	19,338,556

Revolving Line of Credit

On December 20, 2018, certain wholly owned subsidiaries (the “Subsidiaries”) of the Company entered into a revolving credit loan agreement (the “Agreement”) between the Subsidiaries and TCF National Bank (the “Lender”). Under the Agreement, the Subsidiaries are borrowing from the Lender in the principal amount of up to $10 million pursuant to a promissory note (the “Note”). The Note bears an interest rate equal to 3.00% over the One Month U.S. Dollar London Inter-Bank Offered Rate and is due to mature on December 20, 2021. The obligations under the Agreement are secured by certain real estate assets owned by the Subsidiaries.

The Company entered into a guaranty of payment on December 20, 2018 (the “Guaranty,” and together with the Agreement, the Note and related instruments, the “Revolver”) to guarantee the payment to Lender of certain obligations of the Subsidiaries under the Agreement.

The Revolver requires the Subsidiaries and the Company to comply with certain covenants, including, among others, customary financial covenants. The Lender may accelerate amounts outstanding under the Loan Documents upon the occurrence of an Event of Default (as defined in the Agreement) including, but not limited to, the failure to pay amounts due to the Lender or commencement of bankruptcy proceedings.

The Company incurred issuance costs of $477,981 and such costs are amortized as an adjustment to interest expense over the term of the loan. The Company recorded amortization expense of $159,327 and $6,785 for the years ended December 31, 2019 and 2018, respectively. The outstanding loan balance under the Revolver was $4,914,000 and $0 as of December 31, 2019 and 2018, respectively.

Leases [Abstract]

Leases

9. LEASES

Global Self Storage as Lessor

The Company's property rental revenue is primarily related to rents received from tenants at its operating stores. The Company's leases with its self storage tenants are generally on month-to-month terms, include automatic monthly renewals, allow flexibility to increase rental rates over time as market conditions permit, and provide for the collection of contingent fees such as late fees. These leases do not include any terms or conditions that allow the tenants to purchase the leased space. All self-storage leases for which the Company acts as lessor have been classified as operating leases. The real estate assets related to the Company's stores are included in "Real estate assets, net" on the Company's consolidated balance sheets and are presented at historical cost less accumulated depreciation and impairment, if any. Rental income related to these operating leases is included in Property rental revenue on the Company's consolidated statements of operations, and is recognized each month during the month-to-month terms at the rental rate in place during each month.

Global Self Storage as Lessee

The Company is a lessee in a lease agreement for an automobile entered into November 2019 with a lease term of 3 years. The lease agreement does not contain any material residual value guarantees or material restrictive covenants. As a result of the Company’s election of the package of practical expedients permitted within ASC 842, which among other things, allows for the carryforward of historical lease classification, all of the Company’s lease agreements have been classified as operating leases. Lease expense for payments related to the Company’s operating leases is recognized on a straight-line basis over the lease term.

Right-of-use assets represent the Company’s right to use an underlying asset during the lease term and lease liabilities represent the Company’s obligation to make lease payments as specified in the lease. Right-of-use assets and lease liabilities related to the Company’s operating leases are recognized at the lease commencement date based on the present value of the remaining lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available surrounding the Company’s secured borrowing rates and implied secured spread at the lease commencement date in determining the present value of lease payments. The right-of-use asset also includes any lease payments made at or before lease commencement less any lease incentives. Upon adoption of ASC 842 on January 1, 2019, the Company had no right-of-use assets and lease liabilities related to its operating leases. As of December 31, 2019, the Company had right-of-use assets and lease liabilities related to its operating leases of $37,700 and $37,700, which are included in Other assets, net and Accounts payable, accrued expenses and other liabilities on the Company’s consolidated balance sheets, respectively. As of December 31, 2019, the Company’s weighted average remaining lease term and weighted average discount rate related to its operating leases were approximately 3 years and 4.78%, respectively.

The future minimum lease payments under the automobile lease are $14,254, $14,254, and $11,878 for the years ending December 31, 2020, 2021, and 2022, respectively.

Certain officers and directors of the Company also serve as officers and directors of Winmill & Co. Incorporated (“Winco”), Bexil, Tuxis, and their affiliates (collectively with the Company, the “Affiliates”). As of December 31, 2019, certain of the Affiliates owned approximately 5% of the Company’s outstanding common stock. Pursuant to an arrangement between a professional employer organization (“PEO”) and the Affiliates, the PEO provides payroll, benefits, compliance, and related services for employees of the Affiliates in accordance with applicable rules and regulations under the IRC and, in connection therewith, Midas Management Corporation (“MMC”), a subsidiary of Winco, acts as a conduit payer of compensation and benefits to the Affiliates’ employees including those who are concurrently employed by the Company and its Affiliates. Rent expense of concurrently used office space and overhead expenses for various concurrently used administrative and support functions incurred by the Affiliates are allocated at cost among them. The Affiliates participate in a 401(k) retirement savings plan for substantially all qualified employees. A matching expense based upon a percentage of contributions to the plan by eligible employees is incurred and allocated among the Affiliates. The matching expense is accrued and funded on a current basis and may not exceed the amount permitted as a deductible expense under the IRC. The aggregate rent and overhead accrued and paid by the Company to Winco for the years ended December 31, 2019 and 2018 was $77,850 and $53,969, respectively. The Company had reimbursements payable to MMC and Winco for compensation and benefits and rent and overhead of $19,096 and $20,885 as of December 31, 2019 and 2018, respectively.

The Company currently reimburses monthly automobile expenses of $1,000 per month to its President, Mark C. Winmill. To the extent that the monthly payment under the Company’s automobile lease exceeds the current monthly reimbursement amount, Mr. Winmill voluntarily reimburses the Company for the excess amount. In this regard, Mr. Winmill has reimbursed the Company $3,228 and $3,228 for the years ended December 31, 2019 and 2018, respectively.

The Company leases office space and storage to certain Affiliates under a rental agreement. The terms of occupancy are month to month and automatically renew unless terminated by either party on ten days’ written notice. The Company earned rental income of $9,204 and $9,204 for the years ended December 31, 2019 and 2018, respectively.

In December 2019, the Company paid Tuxis $900,000 in connection with the purchase of a property made in 2016.

Stock-Based Compensation

13. STOCK-BASED COMPENSATION

On October 16, 2017 (“Effective Date”), the Company’s stockholders approved the Company’s 2017 Equity Incentive Plan (the “Plan”). The Plan is designed to provide equity-based incentives to certain eligible persons, as defined in the Plan, in the form of options, share appreciation rights, restricted stock, restricted stock units, dividend equivalent rights or other forms of equity-based compensation as determined in the discretion of the Board of Directors, the Compensation Committee of the Board of Directors, or other designee thereof. The total number of shares of common stock reserved and available for issuance under the Plan on the Effective Date was 760,000.

The Company approved restricted stock awards under the Plan to certain of its officers and employees during 2019 in the aggregate amount of 28,755 shares, of which 13,730 shares are time-based grants and 15,025 shares are performance-based grants. During 2018, the Company approved restricted stock awards under the Plan of 73,155 shares, of which 58,130 shares are time-based grants and 15,025 shares are performance-based grants. The Company recorded $102,990 and $80,771 of expense in general and administrative expense in its statement of operations related to restricted stock awards for the years ended December 31, 2019 and 2018, respectively. At December 31, 2019, there was $171,556 and $116,464 of unrecognized compensation expense related to unvested time-based and performance-based restricted stock awards, respectively. That cost is expected to be recognized over a weighted—average period of 2.44 years and 2.66 years for time-based and performance-based awards, respectively. The fair value of common stock awards is determined based on the closing trading price of the Company’s common stock on the grant date.

Time-Based Restricted Stock Grants

These time-based grants vest solely based on continued employment, with 6.25% of the shares eligible to vest on each three-month anniversary of the grant date during the four-year vesting period. Time-based restricted stock cannot be transferred during the vesting period. Grants of time-based restricted stock entitle the holder to dividends paid by the Company on shares of its common stock.

A summary of the Company’s time-based restricted stock grant activity is as follows:

				Weighted-Average
				Grant-Date
Time-Based Restricted Stock Grants	Stock			Fair Value
Unvested at December 31, 2018		47,228		$	4.42
Granted		13,730		$	3.94
Vested		(16,065	)	$	4.36
Forfeited		(4,961	)	$	4.15
Unvested at December 31, 2019		39,932		$	4.31

Performance-Based Restricted Stock Grants

Performance-based restricted stock grants vest based on continued employment and the achievement of certain Funds from Operations, as adjusted (“AFFO”) and same store revenue growth (“SSRG”) goals by the Company during 2019. Between 0% and 200% of these shares will be earned based on achievement of the AFFO and SSRG goals in 2019, and the shares which are earned will remain subject to quarterly vesting during the remaining four-year time vesting period. Dividends paid by the Company prior to the determination of how many shares are earned will be retained by the Company and released only with respect to earned shares. If a Change in Control (as defined in the Plan) occurs during 2019, the number of shares earned will equal the greater of the number of shares granted and the number of shares which would have been earned based on the AFFO and SSRG through the date of the Change in Control. If following a Change in Control, a grantee is terminated by the Company without Cause or by the grantee with Good Reason (as each is defined in the Plan), all unvested restricted stock will fully vest. Performance-based restricted stock earned during 2019 and 2018 were 15,025 shares and 27,613 shares, respectively.

A summary of the Company’s performance-based restricted stock grant activity is as follows:

				Weighted-Average
				Grant-Date
Performance-based Stock Grants	Stock			Fair Value
Unvested at December 31, 2018		15,025		$	4.42
Granted		27,613		$	4.16
Vested		(14,899	)	$	4.33
Unvested at December 31, 2019		27,739		$	4.21

Forfeitures are accounted for as they occur, compensation cost previously recognized for an award that is forfeited because of a failure to satisfy a service or performance condition is reversed in the period of the forfeiture.

On March 11, 2020, the World Health Organization declared the novel coronavirus (“COVID-19”) as a pandemic, and on March 13, 2020 the United States declared a national emergency with respect to COVID-19. The outbreak of COVID-19 has severely impacted global economic activity and caused significant volatility and negative pressure in financial markets. The global impact of the outbreak has been rapidly evolving and many countries, including the United States, have reacted by instituting quarantines, mandating business and school closures and restricting travel. Such actions are creating disruption in global supply chains, and adversely impacting a number of industries, such as transportation, hospitality and entertainment. The outbreak could have a continued adverse impact on economic and market conditions and trigger a period of global economic slowdown. The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19. Nevertheless, COVID-19 presents material uncertainty and risk with respect to the to the Company's business, financial condition, results of operations and cash flows, such as the potential negative impact to occupancy at its properties, financing arrangements, increased costs of operations, changes in law and/or regulation, and uncertainty regarding government and regulatory policy. Accordingly, the Company cannot predict the extent to which its financial condition and results of operations will be affected at this time.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

Upon deregistration as an investment company, effective January 19, 2016, the Company’s status changed to an operating company from an investment company since it no longer met the assessment of an investment company under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946 (“ASC 946”). The Company discontinued applying the guidance in ASC 946 and began to account for the change in status prospectively by accounting for its investments in accordance with other U.S. generally accepted accounting principles (“GAAP”) topics as of the date of the change in status.

The consolidated financial statements of the Company are presented on the accrual basis of accounting in accordance with GAAP and include the accounts of the Company and its wholly owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.

Reclassifications

Reclassifications

Certain amounts from the prior year have been reclassified to conform to current year presentation as described below.

Accounting Standards Adopted

Accounting Standards Adopted

In February 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-02 - Leases (Topic 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either financing or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification determines whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less are accounted for similar to previous guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to previous guidance for sales-type leases, direct financing leases and operating leases. The Company adopted the standard on January 1, 2019, the date it became effective for public companies, using the modified retrospective approach whereby the cumulative effect of adoption was recognized on the adoption date and prior periods were not restated. There was no net cumulative effect adjustment to retained earnings as of January 1, 2019 as a result of this adoption. Upon adoption, the Company elected the package of practical expedients permitted within the standard, which among other things, allows for the carryforward of historical lease classification. The Company also elected the practical expedient provided to lessors in a subsequent amendment to the standard that removed the requirement to separate lease and nonlease components, provided certain conditions were met. Refer to note 9 for the impact of the adoption of ASU No. 2016-02 – Leases (Topic 842) on the Company’s consolidated financial statements.

Cash, Cash Equivalents, and Restricted Cash

Cash, Cash Equivalents, and Restricted Cash

The Company’s cash is deposited with financial institutions located throughout the United States and at times may exceed federally insured limits. The Company considers all highly liquid investments, which may include money market fund shares, with a maturity of three months or less to be cash equivalents. Restricted cash is comprised of escrowed funds deposited with a bank relating to capital expenditures.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash in our consolidated balance sheets to the total amount shown in our consolidated statements of cash flows:

	December 31, 2019		December 31, 2018
Cash and cash equivalents	$	3,990,160	$	1,526,203
Restricted cash		263,405		186,063
Total cash, cash equivalents, and restricted cash as shown in our consolidated statements of cash flows	$	4,253,565	$	1,712,266

Income Taxes

Income Taxes

The Company has elected to be treated as a REIT under the IRC. In order to maintain its qualification as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax with respect to that portion of its income which meets certain criteria and is distributed annually to stockholders. The Company plans to continue to operate so that it meets the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. If the Company were to fail to meet these requirements, it would be subject to federal income tax. In managements opinion, the requirements to maintain these elections are being met. The Company is subject to certain state and local taxes.

The Company has elected to treat its corporate subsidiary, SSG TRS LLC, as a taxable REIT subsidiary (“TRS”). In general, the Company’s TRS may perform additional services for tenants and may engage in any real estate or non-real estate related business. A TRS is subject to federal corporate income tax.

The Company recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. The Company has reviewed its tax positions and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on federal, state, and local income tax returns for open tax years (2016 – 2018), or is expected to be taken in the Company’s 2019 tax returns.

Marketable Equity Securities

Marketable Equity Securities

Investments in equity securities that have readily determinable fair values are accounted for equity securities measured at fair value. Gains or losses from changes in the fair value of equity securities are recorded in net income, until the investment is sold or otherwise disposed. The specific identification method is used to determine the realized gain or loss on investments sold or otherwise disposed.

Fair value is determined using a valuation hierarchy generally by reference to an active trading market, using quoted closing or bid prices. Judgment is used to ascertain if a formerly active market has become inactive and in determining fair values when markets have become inactive.

Real Estate Assets

Real Estate Assets

Real estate assets are carried at the appreciated value as of January 19, 2016, the effective date of the change in status to an operating company, less accumulated depreciation from that date. Purchases subsequent to the effective date of the change in status are carried at cost, less accumulated depreciation and impairment losses. Direct and allowable internal costs associated with the development, construction, renovation, and improvement of real estate assets are capitalized. Property taxes and other costs associated with development incurred during the construction period are capitalized. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use.

Acquisition costs are accounted for in accordance with Accounting Standard Update (“ASU”) No. 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business, which was adopted on January 1, 2018 and are generally capitalized. When stores are acquired, the purchase price is allocated to the tangible and intangible assets acquired and liabilities assumed based on estimated fair values. Allocations to land, building and improvements, and equipment are recorded based upon their respective fair values as estimated by management.

In allocating the purchase price for an acquisition, the Company determines whether the acquisition includes intangible assets or liabilities. The Company allocates a portion of the purchase price to an intangible asset attributed to the value of in-place leases. This intangible is generally amortized to expense over the expected remaining term of the respective leases. Substantially all of the leases in place at acquired stores are at market rates, as the majority of the leases are month-to-month contracts. 

Internal transaction costs associated with acquisitions or dispositions of real estate, as well as repairs and maintenance costs, are charged to expense as incurred. Major replacements and betterments that improve or extend the life of the asset are capitalized and depreciated over their estimated useful lives. Depreciation is computed using the straight-line method over the estimated useful lives of the buildings and improvements, which are generally between 5 and 39 years.

Derivative Financial Instruments

Derivative Financial Instruments

The Company carries all derivative financial instruments on the balance sheet at fair value. Fair value of derivatives is determined by reference to observable prices that are based on inputs not quoted on active markets, but corroborated by market data. The accounting for changes in the fair value of a derivative instrument depends on whether the derivative has been designated and qualifies as part of a hedging relationship. The Company’s use of derivative instruments has been limited to an interest rate cap agreement. The fair values of derivative instruments are included in prepaid expenses and other assets in the accompanying balance sheets. For derivative instruments not designated as cash flow hedges, the unrealized gains and losses are included in interest expense in the accompanying statements of operations. For derivatives designated as cash flow hedges, the effective portion of the changes in the fair value of the derivatives is initially reported in accumulated other comprehensive income (loss) in the Company’s balance sheets and subsequently reclassified into earnings when the hedged transaction affects earnings. The valuation analysis of the interest rate cap reflects the contractual terms of derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves.

Accounts Payable and Accrued Expenses

Accounts Payable and Accrued Expenses

Accounts payable and accrued expenses primarily consist of property tax accruals, unearned rental income, and trade payables.

Revenue and Expense Recognition

Revenue and Expense Recognition

Revenues from stores, which are primarily composed of rental income earned pursuant to month-to-month leases for storage space, as well as associated late charges and administrative fees, are recognized as earned in accordance with ASU Leases-Topic 842. Promotional discounts reduce rental income over the promotional period. Ancillary revenues from sales of merchandise and tenant insurance and other income are recognized when earned.

The Company's management fees are earned subject to the terms of the related property management services agreements (“PSAs”). These PSAs provide that the Company will perform management services, which include leasing and operating the property and providing accounting, marketing, banking, maintenance and other services. These services are provided in exchange for monthly management fees, which are based on a percentage of revenues collected from stores owned by third parties. PSAs generally have original terms of three years, after which management services are provided on a month-to-month basis unless terminated. Management fees are due on the last day of each calendar month that management services are provided.

The Company accounts for the management services provided to a customer as a single performance obligation which are rendered over time each month in accordance with ASU Contracts with Customers-Topic 606. The total amount of consideration from the contract is variable as it is based on monthly revenues, which are influenced by multiple factors, some of which are outside the Company's control. Therefore, the Company recognizes the revenue at the end of each month once the uncertainty is resolved. No disaggregated information relating to PSAs is presented as there is only one contract for the year ended December 31, 2019.

The Company accrues for property tax expense based upon actual amounts billed and, in some circumstances, estimates and historical trends when bills or assessments have not been received from the taxing authorities or such bills and assessments are in dispute. Cost of operations and general and administrative expense are expensed as incurred.

Credit Risk

Credit Risk

Financial assets that are exposed to credit risk consist primarily of cash and cash equivalents and certain portions of accounts receivable including rents receivable from our tenants. Cash and cash equivalents are on deposit with highly rated commercial banks.

Evaluation of Asset Impairment

Evaluation of Asset Impairment

The Company evaluates its real estate assets, intangible assets consisting of in-place lease, and goodwill for impairment annually. If there are indicators of impairment and we determine that the asset is not recoverable from future undiscounted cash flows to be received through the asset’s remaining life (or, if earlier, the expected disposal date), we record an impairment charge to the extent the carrying amount exceeds the asset’s estimated fair value or net proceeds from expected disposal.

The Company evaluates goodwill for impairment annually and whenever relevant events, circumstances, and other related factors indicate that fair value may be less that carrying amounts. If it is determined that the carrying amount of goodwill exceeds the amount that would be allocated to goodwill if the reporting unit were acquired for estimated fair value, an impairment charge is recorded. There were no indicators of impairment and no impairment charges were recorded during 2019 or 2018.

Stock-based Compensation

Stock-based Compensation

The measurement and recognition of compensation expense for all stock-based payment awards to employees are based on estimated fair values. Awards granted are valued at fair value and any compensation expense is recognized over the service periods of each award. For awards granted which contain a graded vesting schedule and the only condition for vesting is a service condition, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For awards granted for which vesting is subject to a performance condition, compensation cost is recognized over the requisite service period if and when the Company concludes it is probable that the performance condition will be achieved.

Loan Procurement Costs

Loan Procurement Costs

Loan procurement costs, net are presented as a direct deduction from the carrying amount of the related debt liability. If there is not an associated debt liability recorded on the consolidated balance sheets, the costs are recorded as an asset net of accumulated amortization. Loan procurement costs associated with the Company's revolving credit facility remain in Line of credit issuance costs, net of amortization on the Company's consolidated balance sheets. The costs are amortized over the estimated life of the related debt.

Use of Estimates

Use of Estimates

The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could materially differ from management’s estimates.

Recently Issued Accounting Standards

Recently Issued Accounting Standards

In August 2017, the FASB issued ASU No. 2017-12 – Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The standard became effective on January 1, 2020 and is not expected to have a material impact on the Company’s consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13 – Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new guidance changes how entities measure credit losses for most financial assets. This standard requires an entity to estimate its lifetime expected credit loss and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. In November 2018, the FASB issued ASU No. 2018-19 – Codification Improvements to Topic 326, Financial Instruments - Credit Losses, which clarifies that receivables arising from operating leases are within the scope of the leasing standard (ASU No. 2016-02), and not within the scope of ASU No. 2016-13. The standard became effective on January 1, 2020 and is not expected to have a material impact on the Company’s consolidated financial statements.
