ORGANIZATION

ORGANIZATION
ORGANIZATION	Note 1 - Organization Sterling Real Estate Trust (“Sterling”, “the Trust” or “the Company”) is a registered, but unincorporated business trust organized in North Dakota in December 2002. Sterling has elected to be taxed as a Real Estate Investment Trust (“REIT”) under Sections 856-860 of the Internal Revenue Code, which requires that 75% of the assets of a REIT must consist of real estate assets and that 75% of its gross income must be derived from real estate. The net income of the REIT is allocated in accordance with the stock ownership in the same fashion as a regular corporation. Sterling previously established an operating partnership (“Sterling Properties, LLLP”) and transferred all of its assets and liabilities to the operating partnership in exchange for general partnership units. As the general partner, Sterling has management responsibility for all activities of the operating partnership. As of December 31, 2015 and 2014 , Sterling owned approximately 33.12% and 27.77% , respectively, of the operating partnership.

PRINCIPAL ACTIVITY AND SIGNIFICANT ACCOUNTING POLICIES
PRINCIPAL ACTIVITY AND SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 – PRINCIPAL ACTIVITY AND SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements include the accounts of Sterling and all subsidiaries for which we maintain a controlling interest. The accompanying consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”) and require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting periods. Actual results could differ from those estimates. Principles of Consolidation The consolidated financial statements include the accounts of Sterling , Sterling Properties, LLLP, and wholly-owned limited liability companies. All significant intercompany transactions and balances have been eliminated in consolidation. Additionally, we evaluate the need to consolidate affiliates based on standards set forth in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation (“ASC 810”). In determining whether we have a requirement to consolidate the accounts of an entity, management considers factors such as our ownership interest, our authority to make decisions and contractual and substantive participating rights of the limited partners and shareholders, as well as whether the entity is a variable interest entity (“VIE”) for which we have both: a) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance, and b) the obligation to absorb losses or the right to receive benefits from the VIE that could be potentially significant to the VIE. Principal Business Activity Sterling currently owns directly and indirectly, 146 properties. The Trust’s 97 residential properties are located in North Dakota, Minnesota, Missouri and Nebraska and are principally multifamily apartment buildings. The Trust owns 49 commercial properties primarily located in North Dakota with others located in Arkansas, Colorado, Iowa, Louisiana, Michigan, Minnesota, Mississippi, Texas and Wisconsin. The commercial properties include retail, office, industrial, restaurant and medical properties. Presently, the Trust’s mix of properties is 68.0% residential and 32.0% commercial (based on cost) and total $594,509 in real estate investments at December 31, 2015 . Effective January 1, 2016, our focus will be limited to multifamily apartment properties. We currently have no plans with respect to our non-multifamily apartment properties. Residential Property Location No. of Properties Units North Dakota Minnesota Missouri Nebraska Commercial Property Location No. of Properties Sq. Ft North Dakota Arkansas Colorado Iowa Louisiana Michigan Minnesota Mississippi Texas Wisconsin Concentration of Credit Risk Our cash balances are maintained in various bank deposit accounts. The bank deposit amounts in these accounts may exceed federally insured limits at various times throughout the year. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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 differ from those estimates. Real Estate Investments We account for our property acquisitions by allocating the purchase price of a property to the property’s assets based on management’s estimates of fair value. Techniques used to estimate fair value include an appraisal of the property by a certified independent appraiser at the time of acquisition. Significant factors included in the independent appraisal include items such as current rent schedules, occupancy levels, and discount factors. Property valuations are completed primarily using the income capitalization approach, in which anticipated benefits are converted to an indication of current value. The total value allocable to intangible assets acquired, which consists of unamortized lease origination costs, in-place leases and tenant relationships, are allocated based on management’s evaluation of the specific characteristics of each tenant’s lease, our overall relationship with that respective tenant, growth prospects for developing new business with the tenant, the remaining term of the lease and the tenant’s credit quality, among other factors. The value allocable to the above or below market component of an acquired in-place lease is determined based upon the present value (using a market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining term, and (ii) management’s estimate of rents that would be paid using fair market rates over the remaining term of the lease. The amounts allocated to above or below market leases are included in lease intangibles, net, in the accompanying balance sheets and are amortized on a straight-line basis as an increase or reduction of rental income over the remaining non-cancelable term of the respective leases. We estimate the in-place lease value for each lease acquired. This fair value estimate is calculated using factors available in third party appraisals or cash flow estimates of the property prepared by our internal analysis. These estimates are based upon cash flow projections for the property, existing leases, and the current economic climate. Our analysis results in three discrete financial items: assets for above market leases, liabilities for below market leases, and assets for the in-place lease value. The calculation of each of these components is performed in tandem to provide a complete intangible asset value. Key factors considered in the calculation of fair value of both real property and intangible assets include the current market rent values, “dark” periods (building in vacant status), direct costs estimated with obtaining a new tenant, discount rates, escalation factors, standard lease terms, and tenant improvement costs. Furniture and fixtures are stated at cost less accumulated depreciation. All costs associated with the development and construction of real estate investments, including acquisition fees and interest, are capitalized as a cost of the property. Expenditures for renewals and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized. Expenditures for routine maintenance and repairs, which do not add to the value or extend useful lives, are charged to expense as incurred. Depreciation is provided for over the estimated useful lives of the individual assets using the straight-line method over the following estimated useful lives: Buildings and improvements 40 years Furniture, fixtures and equipment 5 - 9 years Depreciation expense for the years ended December 31, 2015 and 2014 totaled $16,466 and $12,116 , respectively. The Company’s investment properties are reviewed for potential impairment at the end of each reporting period whenever events or changes in circumstances indicate that the carrying value may not be recoverable. At the end of each reporting period, the Company separately determines whether impairment indicators exist for each property. Examples of situations considered to be impairment indicators include, but are not limited to: · a substantial decline or continued low occupancy rate; · continued difficulty in leasing space; · significant financial troubled tenants; · a change in plan to sell a property prior to the end of its useful life or holding period; · a significant decrease in market price not in line with general market trends; and · any other quantitative or qualitative events or factors deemed significant by the Company’s management or board of trustees. If the presence of one or more impairment indicators as described above is identified at the end of the reporting period or throughout the year with respect to an investment property, the asset is tested for recoverability by comparing its carrying value to the estimated future undiscounted cash flows. An investment property is considered to be impaired when the estimated future undiscounted cash flows are less than its current carrying value. When performing a test for recoverability or estimating the fair value of an impaired investment property, the Company makes complex or subjective assumptions which include, but are not limited to: · projected operating cash flows considering factors such as vacancy rates, rental rates, lease terms, tenant financial strength, demographics, holding period and property location; · projected capital expenditures and lease origination costs; · projected cash flows from the eventual disposition of an operating property using a property specific capitalization rate; · comparable selling prices; and · property specific discount rates for fair value estimates as necessary. To the extent impairment has occurred, the Company will record an impairment charge calculated as the excess of the carrying value of the asset over its fair value for impairment of investment properties. Based on evaluation, management recorded a loss on impairment of property of $412 during the year ended December 31, 2015. There was no impairment losses during the year ended December 31, 2014 . Properties Held for Sale We account for our properties held for sale in accordance with ASC 360, Property, Plant and Equipment (“ASC 360”), which addresses financial accounting and reporting in a period in which a component or group of components of an entity either has been disposed of or is classified as held for sale. In accordance with ASC 360, at such time as a property is held for sale, such property is carried at the lower of (1) its carrying amount or (2) fair value less costs to sell. In addition, a property being held for sale ceases to be depreciated. We classify operating properties as properties held for sale in the period in which all of the following criteria are met: · management, having the authority to approve the action, commits to a plan to sell the asset; · the asset is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets; · an active program to locate a buyer and other actions required to complete the plan to sell the asset has been initiated; · the sale of the asset is probable and the transfer of the asset is expected to qualify for recognition as a completed sale within one year; · the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and · given the actions required to complete the plan to sell the asset, it is unlikely that significant changes to the plan would be made or that the plan would be withdrawn. The results of operations of a component of an entity that either has been disposed of or is classified as held-for-sale under the requirements of ASC 360, shall be reported in discontinued operations in accordance with ASC 205, Presentation of Financial Statements (“ASC 205”) if the following condition is met: · represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. There was one property classified as held for sale at December 31, 2015 , and no properties classified as held for sale at December 31, 2014. See Note 19. Construction in Progress The Company capitalizes direct and certain indirect project costs incurred during the development period such as construction, insurance, architectural, legal, interest and other financing costs, and real estate taxes. At such time as the development is considered substantially complete, the capitalization of certain indirect costs such as real estate taxes and interest and financing costs cease and all project-related costs included in construction in process are reclassified to land and building and other improvements. Cash and Cash Equivalents We classify highly liquid investments with a maturity of three months or less when purchased as cash equivalents. Investment in Unconsolidated Affiliates We account for unconsolidated affiliates using the equity method of accounting per guidance established under ASC 323, Investments – Equity Method and Joint Ventures (“ASC 323”). The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for our share of equity in the affiliates’ earnings and distributions. We evaluate the carrying amount of the investments for impairment in accordance with ASC 323. Unconsolidated affiliates are reviewed for potential impairment if the carrying amount of the investment exceeds its fair value. An impairment charge is recorded when an impairment is deemed to be other-than-temporary. To determine whether impairment is other-than-temporary, we consider whether we have the ability and intent to hold the investment until the carrying amount is fully recovered. The evaluation of an investment in an affiliate for potential impairment can require our management to exercise significant judgments. No impairment losses were recorded related to the unconsolidated affiliates for the years ended December 31, 2015 and 2014 . We use the equity method to account for investments that qualify as variable interest entities where we are not the primary beneficiary and entities that we do not control or where we do not own a majority of the economic interest but have the ability to exercise significant influence over the operations and financial policies of the investee. We will also use the equity method for investments that do not qualify as variable interest entities and do not meet the control requirements for consolidation, as defined in ASC 810. For a joint venture accounted for under the equity method, our share of net earnings and losses is reflected in income when earned and distributions are credited against our investment in the joint venture as received. In determining whether an investment in a limited liability company or tenant in common is a variable interest entity, we consider: the form of our ownership interest and legal structure; the size of our investment; the financing structure of the entity, including the necessity of subordinated debt; estimates of future cash flows; our and our partner’s ability to participate in the decision making related to acquisitions, dispositions, budgeting and financing on the entity; and obligation to absorb losses and preferential returns. As of December 31, 2015 , we assessed one of our liability liability company arrangements as a variable interest entity where we were not the primary beneficiary. In addition, four of our tenant in common arrangements do not qualify as variable interest entities and do not meet the control requirements for consolidation, as defined in ASC 810. As of December 31, 2015 and 2014 , the unconsolidated affiliates held total assets of $ 32,296 and $ 32,459 and mortgage notes payable of $ 20,421 and $ 20,803 , respectively. The operating partnership owns a 40.26% interest in a single asset limited liability company which owns a 144 unit residential, multifamily apartment complex in Bismarck, North Dakota. The property is encumbered by a first mortgage with a balance at December 31, 2015 and 2014 of $2,259 and $ 2,323 , respectively. We owed $909 and $ 935 of our respective share of the mortgage loan balance as of December 31, 2015 and 2014 , respectively. The Company is jointly and severally liable for the full mortgage balance. The operating partnership is a 50% owner of Grand Forks Marketplace Retail Center through 100% ownership in a limited liability company. Grand Forks Marketplace Retail Center has approximately 183,000 square feet of commercial space in Grand Forks, North Dakota. The property is encumbered by a non-recourse first mortgage with a balance at December 31, 2015 and 2014 of $ 11,079 and $ 11,260 , respectively. We owed $ 5,540 and $ 5,630 for our respective share of the mortgage loan balance as of December 31, 2015 and 2014 , respectively. The Company is jointly and severally liable for the full mortgage balance. The operating partnership owns a 66.67% interest as tenant in common in an office building with approximately 75,000 square feet of commercial rental space in Fargo, North Dakota. The property is encumbered by a first mortgage with a balance at December 31, 2015 and 2014 of $ 7,083 and $ 7,221 , respectively. We owed $ 4,722 and $ 4,814 for our respective share of the mortgage loan balance on December 31, 2015 and 2014 , respectively. The Company is jointly and severally liable for the full mortgage balance. The operating partnership owns an 82.50% interest as a tenant in common in a 61 unit residential, multifamily apartment complex in Fargo, North Dakota. The property was unencumbered at December 31, 2015 and 2014 , respectively . The operating partnership is a 99% owner of Michigan Street Transit Center, LLC (“Transit Center”) through 100% ownership in a limited liability company. The operating partnership has contributed approximately $644 in cash and $1,316 in property contributions to the Transit Center in May and June 2014, respectively. As of December 31, 2015, the property owned by the Transit Center consisted of land previously occupied by a building and parking ramp in Duluth, Minnesota which were both demolished during 2014. The property was unencumbered at December 31, 2015 and 2014 , respectively . Receivables Receivables consist primarily of amounts due for rent and real estate taxes. The receivables are non-interest bearing. The carrying amount of receivables is reduced by an amount that reflects management’s best estimates of the amounts that will not be collected. As of December 31, 2015 and 2014 , management determined no allowance was necessary for uncollectible receivables. Financing and Lease Costs Financing costs have been capitalized and are being amortized over the life of the financing using the effective interest method. Unamortized financing costs are written off when debt is retired before the maturity date and included in amortization expense at that time. Lease costs incurred in connection with new leases have been capitalized and are being amortized over the life of the lease using the straight-line method. Intangible Assets Lease intangibles are a purchase price allocation recorded on property acquisition. The lease intangibles represent the estimated value of in-place leases, tenant relationships and the value of leases with above or below market lease terms. Lease intangibles are amortized over the term of the related lease. The carrying amount of intangible assets is regularly reviewed for indicators of impairments in value. Impairment is recognized only if the carrying amount of the intangible asset is considered to be unrecoverable from its undiscounted cash flows and is measured as the difference between the carrying amount and the estimated fair value of the asset. Based on the review, management determined no impairment charges were necessary at December 31, 2015 and 2014 . Noncontrolling Interest A noncontrolling interest in a subsidiary (minority interest) is in most cases an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements and separate from the parent company’s equity. In addition, consolidated net income is required to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest and the amount of consolidated net income attributable to the parent and the noncontrolling interest are required to be disclosed on the face of the consolidated statements of operations and comprehensive income. Operating Partnership: Interests in the operating partnership held by limited partners are represented by operating partnership units. The operating partnership’s income is allocated to holders of units based upon the ratio of their holdings to the total units outstanding during the period. Capital contributions, distributions, syndication costs, and profits and losses are allocated to noncontrolling interests in accordance with the terms of the operating partnership agreement. Partially Owned Properties: The Company reflects noncontrolling interests in partially owned properties on the balance sheet for the portion of properties consolidated by the Company that are not wholly owned by the Company. The earnings or losses from those properties attributable to the noncontrolling interests are reflected as noncontrolling interest in partially owned properties in the consolidated statement of operations and comprehensive income. Syndication Costs Syndication costs consist of costs paid to attorneys, accountants, and selling agents, related to the raising of capital. Syndication costs are recorded as a reduction to beneficial and noncontrolling interest. Federal Income Taxes We have elected to be taxed as a REIT under the Internal Revenue Code, as amended. A REIT calculates taxable income similar to other domestic corporations, with the major difference being a REIT is entitled to a deduction for dividends paid. A REIT is generally required to distribute each year at least 90% of its taxable income. If it chooses to retain the remaining 10% of taxable income, it may do so, but it will be subject to a corporate tax on such income. REIT shareholders are taxed on REIT distributions of ordinary income in the same manner as they are taxed on other corporate distributions. A summary of the tax characterization of the dividends paid to shareholders of the Company’s common stock for the years ended December 31, 2015 and 2014 follows: Tax Year Ended December 31, Dividend % Dividend % 2015 2015 2014 2014 Tax status Ordinary income $ % $ % Capital Gain % % Return of capital % % $ % $ % We intend to continue to qualify as a REIT and, provided we maintain such status, will not be taxed on the portion of the income that is distributed to shareholders. In addition, we intend to distribute all of our taxable income; therefore, no provisions or liabilities for income taxes have been recorded in the financial statements. Sterling conducts its business activity as an Umbrella Partnership Real Estate Investment Trust (“UPREIT”) through its Operating Partnership – Sterling Properties, LLLP. The Operating Partnership is organized as a limited liability limited partnership. Income or loss is allocated to the partners in accordance with the provisions of the Internal Revenue Code 704(b) and 704(c). UPREIT status allows non-recognition of gain by an owner of appreciated real estate if that owner contributes the real estate to a partnership in exchange for a partnership interest. The conversion of a partnership interest to shares of beneficial interest in the REIT will be a taxable event to the limited partner. We follow ASC Topic 740, Income Taxes, to recognize, measure, present and disclose in our consolidated financial statements uncertain tax positions that we have taken or expect to take on a tax return. As of December 31, 2015 and 2014 we did not have any liabilities for uncertain tax positions that we believe should be recognized in our consolidated financial statements. We are no longer subject to Federal and State tax examinations by tax authorities for years before 2012. The operating partnership has elected to record related interest and penalties, if any, as income tax expense on the consolidated statements of operations and other comprehensive income. Revenue Recognition We recognize revenue in accordance with ASC Topic 605, Revenue Recognition, (“ASC Topic 605”). ASC Topic 605 requires that all four of the following basic criteria be met before revenue is realized or realizable and earned: (1) there is persuasive evidence that an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the seller’s price to the buyer is fixed and determinable; and (4) collectability is reasonably assured. We derive over 95% of our revenues from tenant rents and other tenant-related activities. We lease multifamily units under operating leases with terms of one year or less. Rental income and other property revenues are recorded when due from tenants and recognized monthly as earned pursuant to the terms of the underlying leases. Other property revenues consist primarily of laundry, application and other fees charged to tenants. We lease commercial space primarily under long-term lease agreements. Commercial tenant rents include base rents, expense reimbursements (such as common area maintenance, real estate taxes and utilities), and a straight-line rent adjustment. We record base rents on a straight-line basis. The monthly base rent income according to the terms of our leases is adjusted so that an average monthly rent is recorded for each tenant over the term of its lease. The straight-line rent adjustment increased revenue by $325 and $186 for the years ended December 31, 2015 and 2014 , respectively. The straight-line receivable balance included in receivables on the consolidated balance sheets as of December 31, 2015 and 2014 was $ 2,863 and $ 2,538 , respectively. We receive payments for expense reimbursements from substantially all our multi-tenant commercial tenants throughout the year based on estimates. Differences between estimated recoveries and the final billed amounts, which generally are immaterial, are recognized in the subsequent year. Earnings per Common Share Basic earnings per common share is computed by dividing net income available to common shareholders (the “numerator”) by the weighted average number of common shares outstanding (the “denominator”) during the period. Sterling had no dilutive potential common shares as of December 31, 2015 and 2014 , and therefore, basic earnings per common share was equal to diluted earnings per common share for both periods. For the years ended December 31, 2015 and 2014 , Sterling’s denominators for the basic and diluted earnings per common share were approximately 7,223,000 and 5,507,000 , respectively. Recent Accounting Pronouncements In April 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”). In accordance with ASU 2014-08, a discontinued operation represents: (i) a component of an entity or group of components that has been disposed of or is classified as held for sale in a single transaction and represents a strategic shift that has or will have a major effect on an entity’s financial results, or (ii) an acquired business that is classified as held for sale on the date of acquisition. A strategic shift could include a disposal of: (i) a separate major line of business, (ii) a separate major geographic area of operations, (iii) a major equity method investment, or (iv) other major parts of an entity. The standard requires prospective application and will be effective for interim and annual periods beginning on or after December 15, 2014 with early adoption permitted. The standard is not applied to components of an entity that were sold or classified as held for sale prior to the adoption of the standard. We have elected to adopt this standard early, effective January 1, 2014, which primarily has the impact of reflecting gains and losses on the sale of operating properties prospectively within continuing operations, and results in not classifying the operations of such operating properties as discontinued operations in all periods presented. Subsequent to our adoption of ASU 2014-08, the sale of real estate that does not meet the definition of a discontinued operation under the standard will be included in gain on sale of operating properties in our consolidated statements of operations and other comprehensive income. In May 2014, the FASB and International Accounting Standards Board issued their final standard on revenue from contracts with customers, which was issued by the FASB as Accounting Standards Update 2014-09, Revenue from Contracts with Customers , or ASU 2014-09. ASU 2014-09, which establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers, supersedes most current GAAP applicable to revenue recognition and converges U.S. and international accounting standards in this area. The core principle of the new guidance is that revenue shall only be recognized when an entity has transferred control of goods or services to a customer and for an amount reflecting the consideration to which the entity expects to be entitled for such exchange. Additionally, lease contracts are specifically excluded form ASU 2014-09. In July 2015, the FASB decided to defer the effective date for annual reporting periods beginning after December 15, 2017. Early adoption is permitted beginning on the original effective date of periods beginning after December 15, 2016. Upon adoption, ASU 2014-09 allows for full retrospective adoption applied to all periods presented or modified retrospective adoption with the cumulative effect of initially applying the standard recognized at the date of initial application. We have not yet determined the effect ASU 2014-09 will have on our consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis ("ASU 2015-02"). This amends ASC 810, Consolidation (ASC "810"), to improve targeted areas of consolidation guidance by simplifying the requirements of consolidation and placing more emphasis on risk of loss when determining a controlling financial interest. ASU 2015-02 is effective for the annual period ending after December 15, 2015, and subsequent interim and annual periods with early adoption permitted. The adoption of ASU 2015-02 is not expected to have a material impact on the Company's consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03 “ Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” . The objective of ASU 2015-03 is to identify, evaluate, and improve areas of generally accepted accounting principles (GAAP) for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. To simplify presentation of debt issuance costs, the amendments in this ASU require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. In August 2015, the FASB issued ASU No. 2015-15, Interest – Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements , which clarifies that absent authoritative guidance in ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the staff of the Securities and Exchange Commission would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. This ASU is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2015. Early adoption is permitted. The adoption of the standard will result in the reclassification of unamortized debt issuance costs related to the Company’s mortgage notes payable from assets, net to reductions in mortgage notes payable within its consolidated balance sheets as of December 31, 2015 and 2014. Other than this reclassification, the adoption of the standard will not have an impact on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments, which requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period, includi

SEGMENT REPORTING
SEGMENT REPORTING	NOTE 3 – segment reporting We report our results in two reportable segments: residential and commercial properties. Our residential properties include multifamily properties. Our commercial properties include retail, office, industrial, restaurant and medical properties. We assess and measure operating results based on net operating income (“NOI”), which we define as total real estate segment revenues less real estate expenses (which consist of real estate taxes, property management fees, utilities, repairs and maintenance, insurance and direct administrative costs). We believe NOI is an important measure of operating performance even though it should not be considered an alternative to net income or cash flow from operating activities. NOI is unaffected by financing, depreciation, amortization, legal and professional fees and certain general and administrative expenses. The accounting policies of each segment are consistent with those described in Note 2 of this report. Segment Revenues and Net Operating Income The revenues and net operating income for the reportable segments (residential and commercial) are summarized as follows for the years ended December 31, 2015 and 2014 , along with reconciliations to the consolidated financial statements.

Mortgage loan payables, net were $ 383,292 and $ 324,886 as of December 31, 2015 and 2014 , respectively. As of December 31, 2015 , we had 108 fixed rate and no variable rate mortgage loans with effective interest rates ranging from 2.57% to 7.65% per annum and a weighted average effective interest rate of 4.53% per annum. As of December 31, 2014 , we had 90 fixed rate and 1 variable rate mortgage loans with effective interest rates ranging from 2.57% to 7.65% per annum, and a weighted average effective interest rate of 4.70% per annum. As of December 31, 2014 , we had $ 318,554 of fixed rate debt, or 98.05% of mortgage loan payables, at a weighted average interest rate of 4.74% per annum and $ 6,332 of variable rate debt, or 1.95% of mortgage loan payables, net at a weighted average effective interest rate of 2.66% per annum. The majority of the Company’s mortgages payable require monthly payments of principal and interest. Certain mortgages require reserves for real estate taxes and certain other costs. Mortgages are secured by the respective properties, assignment of rents, business assets, deeds to secure debt, deeds of trust and/or cash deposits with the lender. Certain mortgage note agreements include covenants that, in part, impose maintenance of certain debt service coverage and debt to worth ratios. As a result of the December 19, 2014 suburban Minneapolis, Minnesota portfolio acquisition, as of December 31, 2014 the Company was out of compliance with the lender’s post distribution debt service coverage ratio requirement on a consolidated basis. In addition, two loans on residential properties were out of compliance at year-end due to unit renovation repair and maintenance costs. One loan is secured by a property located in Fargo, North Dakota with an outstanding balance of $295 and the other loan is secured by properties located in Fargo, North Dakota with an outstanding balance of $3,446 at December 31, 2014 . The loans were out of compliance with the lender’s debt service coverage ratio requirement as of December 31, 2014. Waivers were received from the lenders.

HEDGING ACTIVITIES
HEDGING ACTIVITIES	NOTE 10 – HEDGING ACTIVITIES As part of our interest rate risk management strategy, we have used derivative instruments to minimize significant unanticipated earnings fluctuations that may arise from rising variable interest rate costs associated with existing borrowings. To meet these objectives, we have entered into interest rate swaps in the notional amount of $1,294 and $2,450 to provide a fixed rate of 7.25% and 2.57% , respectively. The swaps mature in April 2020 and December 2017 , respectively. The swaps were issued at approximate market terms and thus no fair value adjustment was recorded at inception. The carrying amount of the swaps have been adjusted to their fair values at the end of the quarter, which because of changes in forecasted levels of LIBOR, resulted in reporting a liability for the fair value of the future net payments forecasted under the swaps. The interest rate swaps are accounted for as effective hedges in accordance with ASC 815-20 whereby they are recorded at fair value and changes in fair value are recorded to comprehensive income. As of December 31, 2015 and 2014 , we have recorded a liability and accumulated other comprehensive loss of $ 219 and $ 272 , respectively.

FAIR VALUE MEASUREMENT
FAIR VALUE MEASUREMENT	NOTE 11 - FAIR VALUE MEASUREMENT The following table presents the carrying value and estimated fair value of the Company’s financial instruments: December 31, 2015 December 31, 2014 Carrying Carrying Value Fair Value Value Fair Value (in thousands) Financial liabilities: Mortgage notes payable $ $ $ $ Fair value of interest rate swaps $ $ $ $ The carrying values shown in the table are included in the consolidated balance sheets under the indicated captions. ASC 820-10 established a three-level valuation hierarchy for fair value measurement. Management uses these valuation techniques to establish the fair value of the assets at the measurement date. These valuation techniques are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect management’s assumptions. These two types of inputs create the following fair value hierarchy: · Level 1 – Quoted prices for identical instruments in active markets; · Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose significant inputs are observable; · Level 3 – Instruments whose significant inputs are unobservable. The guidance requires the use of observable market data, when available, in making fair value measurements. When inputs used to measure fair value fall within different levels of the hierarchy, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. Recurring Fair Value Measurements The following table presents the Company’s financial instruments, which are measured at fair value on a recurring basis, by the level in the fair value hierarchy within which those measurements fall. Methods and assumptions used to estimate the fair value of these instruments are described after the table. Level 1 Level 2 Level 3 Total (in thousands) December 31, 2015 Fair value of interest rate swaps $ — $ $ — $ December 31, 2014 Fair value of interest rate swaps $ — $ $ — $ Fair value of interest rate swaps: The fair value of interest rate swaps is determined using a discounted cash flow analysis on the expected future cash flows of the derivative. This analysis utilizes observable market data including forward yield curves and implied volatilities to determine the market’s expectation of the future cash flows of the variable component. The fixed and variable components of the derivative are then discounted using calculated discount factors developed based on the LIBOR swap rate and are aggregated to arrive at a single valuation for the period. The Company also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2015 and 2014 , the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation. As a result, the Company has determined that its derivative valuations in their entirety are classified within Level 2 of the fair value hierarchy. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered any applicable credit enhancements. The Company’s derivative instruments are further described in Note 10. Nonrecurring Fair Value Measurements As discussed in Note 2, the Company recorded an impairment charge during the year ended December 31, 2015 to write the carrying value down to estimated fair value for certain investment properties after determining their carrying value exceeded the projected undiscounted cash flows based upon the estimated holding period for such assets. Estimated fair value is determined by the Company utilizing the discounted cash flow models, third-party broker valuation estimates, appraisals, bona fide purchase offers or the expected sales price from an executed sales agreement. Capitalization and discount rates utilized within discounted cash flows models are based upon observable rates that the Company believes to be within a reasonable range of current market rates for the property. Investment properties measured at fair value on a nonrecurring basis at December 31, 2015 and 2014, respectively, aggregated by the level within the fair value hierarchy in which those measurements fall are as follows: Provision for Impairment of Investment Level 1 Level 2 Level 3 Total Properties (in thousands) December 31, 2015 Real estate investments (a) $ — $ — $ $ $ December 31, 2014 Real estate investments $ — $ — $ — $ — $ — (a) Includes an impairment charge recorded on certain investment properties during the year ended December 31, 2015, based upon a discounted cash flow model. Fair Value Disclosures The following table presents the Company’s financial assets and liabilities, which are measured at fair value for disclosure purposes, by the level in the fair value hierarchy within which they fall. Methods and assumptions used to estimate the fair value of these instruments are described after the table. Level 1 Level 2 Level 3 Total (in thousands) December 31, 2015 Mortgage notes payable $ — $ — $ $ December 31, 2014 Mortgage notes payable $ — $ — $ $ Mortgage notes payable: The Company estimates the fair value of its mortgage notes payable by discounting the future cash flows of each instrument at rates currently offered to the Company for similar debt instruments of comparable maturities by the Company’s lenders. Judgment is used in determining the appropriate rate for each of the Company’s individual mortgages and notes payable based upon the specific terms of the agreement, including the term to maturity, the quality and nature of the underlying property and its leverage ratio. The rates used range from 3.97% to 4.05% and from 3.94% to 4.41% at December 31, 2015 and 2014 , respectively. The fair value of the Company’s matured mortgage notes payable were determined to be equal to the carrying value of the properties because there is no market for similar debt instruments and the properties’ carrying value was determined to be the best estimate of fair value as of December 31, 2015 . The Company’s mortgage notes payable are further described in Note 9.

DIVIDEND REINVESTMENT PLAN	NOTE 15 – DIVIDEND REINVESTMENT PLAN Our Board of Trustees approved a dividend reinvestment plan to provide existing holders of our common shares with a convenient method to purchase additional common shares without payment of brokerage commissions, fees or service charges. On July 20, 2012, we registered with the Securities Exchange Commission 2,000,000 common shares to be issued under the plan on Form S-3D, which automatically became effective on July 20, 2012. Under this plan, eligible shareholders may elect to have all or a portion (but not less than 25%) of the cash dividends they receive automatically reinvested in our common shares. If an eligible shareholder elects to reinvest cash dividends under the plan, the shareholder may also make additional optional cash purchases of our common shares, not to exceed $5 per fiscal quarter without our prior approval. The purchase price per common share under the plan equals 95% of the estimated value per common share for dividend reinvestments and equals 100% of the estimated value per common share for additional optional cash purchases, as determined by our Board of Trustees. The estimated value per common share was $ 15.50 and $ 15.00 at December 31, 2015 and 2014 , respectively. See discussion of determination of estimated value in Note 20. Therefore, the purchase price per common share for dividend reinvestments was $ 14.725 and $ 14.25 and for additional optional cash purchases was $ 15.50 and $ 15.00 at December 31, 2015 and 2014 , respectively. The Board, in its sole discretion, may amend, suspend or terminate the plan at any time, without the consent of shareholders, upon a ten day notice to participants. In the year ended December 31, 2015 , 284,000 shares were issued pursuant to dividend reinvestments and 116,000 shares were issued pursuant to additional optional cash purchases under the plan.

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	NOTE 18 - COMMITMENTS AND CONTINGENCIES Environmental Matters Federal law (and the laws of some states in which we own or may acquire properties) imposes liability on a landowner for the presence on the premises of hazardous substances or wastes (as defined by present and future federal and state laws and regulations). This liability is without regard to fault or knowledge of the presence of such substances and may be imposed jointly and severally upon all succeeding landowners. If such hazardous substance is discovered on a property acquired by us, we could incur liability for the removal of the substances and the cleanup of the property. There can be no assurance that we would have effective remedies against prior owners of the property. In addition, we may be liable to tenants and may find it difficult or impossible to sell the property either prior to or following such a cleanup. Risk of Uninsured Property Losses We maintain property damage, fire loss, and liability insurance. However, there are certain types of losses (generally of a catastrophic nature) which may be either uninsurable or not economically insurable. Such excluded risks may include war, earthquakes, tornados, certain environmental hazards, and floods. Should such events occur, (i) we might suffer a loss of capital invested, (ii) tenants may suffer losses and may be unable to pay rent for the spaces, and (iii) we may suffer a loss of profits which might be anticipated from one or more properties. Litigation The Company is subject, from time to time, to various legal proceedings and claims that arise in the ordinary course of business. While the resolution of such matters cannot be predicted with certainty, management believes, based on currently available information, that the final outcome of such matters will not have a material effect on the financial statements of the Company.

The value of units issued in exchange for property is determined through a value established annually by our Board of Trustees, and reflects the fair value at the time of issuance. The following table summarizes the acquisition date fair values, before prorations, the Company recorded in conjunction with the acquisitions discussed above: 2015 2014 Land, building, tenant improvements and FF&E $ $ Acquired lease intangible assets - Acquired lease intangible liabilities - Mortgages notes payable assumed Other liabilities Net assets acquired Equity/limited partnership unit consideration New loans Net cash consideration $ $ Estimated Value of Units/Shares The Board of Trustees determined an estimate of fair value for the trust shares in 2015 and 2014. In addition, the Board of Trustees, acting as general partner for the operating partnership, determined an estimate of fair value for the limited partnership units in 2015 and 2014. In determining this value, the Board relied upon its experience with, and knowledge about, our real estate portfolio and debt obligations. The Board also relied on valuation methodologies that are commonly used in the real estate industry. The methodology used by our board to determine this value was based on the value of our real estate investments, cash and other assets and debt and other liabilities as of a date certain. Based on the results of the methodologies, the Board determined the fair value of the shares and limited partnership units to be $14.00 per share/unit for the first three months of 2014 through March 27, 2014. The Board determined the fair value of the shares and limited partnership units to be $15.00 per share/unit effective March 28, 2014. The Board determined the fair value of the shares and limited partnership units to be $15.50 per share/unit effective February 1, 2015. As with any valuation methodology, the methodologies utilized by the Board in reaching an estimate of the value of the shares and limited partnership units are based upon a number of estimates, assumptions, judgments or opinions that may, or may not, prove to be correct. The use of different estimates, assumptions, judgments, or opinions would likely have resulted in significantly different estimates of the value of the shares and limited partnership units. In addition, the Board’s estimate of share and limited partnership unit value is not based on the fair values of our real estate, as determined by GAAP, as our book value for most real estate is based on the amortized cost of the property, subject to certain adjustments. Furthermore, in reaching an estimate of the value of the shares and limited partnership units, the Board did not include a liquidity discount in order to reflect the fact that the shares and limited partnership units are not currently traded on a national securities exchange; a discount for debt that may include a prepayment obligation or a provision precluding assumption of the debt by a third party; or the costs that are likely to be incurred in connection with an appropriate exit strategy, whether that strategy might be a listing of the limited partnership units or Sterling common shares on a national securities exchange or a merger or sale of our portfolio.

PRINCIPAL ACTIVITY AND SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include the accounts of Sterling and all subsidiaries for which we maintain a controlling interest. The accompanying consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”) and require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting periods. Actual results could differ from those estimates.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Sterling , Sterling Properties, LLLP, and wholly-owned limited liability companies. All significant intercompany transactions and balances have been eliminated in consolidation. Additionally, we evaluate the need to consolidate affiliates based on standards set forth in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation (“ASC 810”). In determining whether we have a requirement to consolidate the accounts of an entity, management considers factors such as our ownership interest, our authority to make decisions and contractual and substantive participating rights of the limited partners and shareholders, as well as whether the entity is a variable interest entity (“VIE”) for which we have both: a) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance, and b) the obligation to absorb losses or the right to receive benefits from the VIE that could be potentially significant to the VIE.
Principal Business Activity	Principal Business Activity Sterling currently owns directly and indirectly, 146 properties. The Trust’s 97 residential properties are located in North Dakota, Minnesota, Missouri and Nebraska and are principally multifamily apartment buildings. The Trust owns 49 commercial properties primarily located in North Dakota with others located in Arkansas, Colorado, Iowa, Louisiana, Michigan, Minnesota, Mississippi, Texas and Wisconsin. The commercial properties include retail, office, industrial, restaurant and medical properties. Presently, the Trust’s mix of properties is 68.0% residential and 32.0% commercial (based on cost) and total $594,509 in real estate investments at December 31, 2015 . Effective January 1, 2016, our focus will be limited to multifamily apartment properties. We currently have no plans with respect to our non-multifamily apartment properties.

Concentration of Credit Risk	Concentration of Credit Risk Our cash balances are maintained in various bank deposit accounts. The bank deposit amounts in these accounts may exceed federally insured limits at various times throughout the year.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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 differ from those estimates.
Real Estate Investments	Real Estate Investments We account for our property acquisitions by allocating the purchase price of a property to the property’s assets based on management’s estimates of fair value. Techniques used to estimate fair value include an appraisal of the property by a certified independent appraiser at the time of acquisition. Significant factors included in the independent appraisal include items such as current rent schedules, occupancy levels, and discount factors. Property valuations are completed primarily using the income capitalization approach, in which anticipated benefits are converted to an indication of current value. The total value allocable to intangible assets acquired, which consists of unamortized lease origination costs, in-place leases and tenant relationships, are allocated based on management’s evaluation of the specific characteristics of each tenant’s lease, our overall relationship with that respective tenant, growth prospects for developing new business with the tenant, the remaining term of the lease and the tenant’s credit quality, among other factors. The value allocable to the above or below market component of an acquired in-place lease is determined based upon the present value (using a market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining term, and (ii) management’s estimate of rents that would be paid using fair market rates over the remaining term of the lease. The amounts allocated to above or below market leases are included in lease intangibles, net, in the accompanying balance sheets and are amortized on a straight-line basis as an increase or reduction of rental income over the remaining non-cancelable term of the respective leases. We estimate the in-place lease value for each lease acquired. This fair value estimate is calculated using factors available in third party appraisals or cash flow estimates of the property prepared by our internal analysis. These estimates are based upon cash flow projections for the property, existing leases, and the current economic climate. Our analysis results in three discrete financial items: assets for above market leases, liabilities for below market leases, and assets for the in-place lease value. The calculation of each of these components is performed in tandem to provide a complete intangible asset value. Key factors considered in the calculation of fair value of both real property and intangible assets include the current market rent values, “dark” periods (building in vacant status), direct costs estimated with obtaining a new tenant, discount rates, escalation factors, standard lease terms, and tenant improvement costs. Furniture and fixtures are stated at cost less accumulated depreciation. All costs associated with the development and construction of real estate investments, including acquisition fees and interest, are capitalized as a cost of the property. Expenditures for renewals and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized. Expenditures for routine maintenance and repairs, which do not add to the value or extend useful lives, are charged to expense as incurred. Depreciation is provided for over the estimated useful lives of the individual assets using the straight-line method over the following estimated useful lives: Buildings and improvements 40 years Furniture, fixtures and equipment 5 - 9 years Depreciation expense for the years ended December 31, 2015 and 2014 totaled $16,466 and $12,116 , respectively. The Company’s investment properties are reviewed for potential impairment at the end of each reporting period whenever events or changes in circumstances indicate that the carrying value may not be recoverable. At the end of each reporting period, the Company separately determines whether impairment indicators exist for each property. Examples of situations considered to be impairment indicators include, but are not limited to: · a substantial decline or continued low occupancy rate; · continued difficulty in leasing space; · significant financial troubled tenants; · a change in plan to sell a property prior to the end of its useful life or holding period; · a significant decrease in market price not in line with general market trends; and · any other quantitative or qualitative events or factors deemed significant by the Company’s management or board of trustees. If the presence of one or more impairment indicators as described above is identified at the end of the reporting period or throughout the year with respect to an investment property, the asset is tested for recoverability by comparing its carrying value to the estimated future undiscounted cash flows. An investment property is considered to be impaired when the estimated future undiscounted cash flows are less than its current carrying value. When performing a test for recoverability or estimating the fair value of an impaired investment property, the Company makes complex or subjective assumptions which include, but are not limited to: · projected operating cash flows considering factors such as vacancy rates, rental rates, lease terms, tenant financial strength, demographics, holding period and property location; · projected capital expenditures and lease origination costs; · projected cash flows from the eventual disposition of an operating property using a property specific capitalization rate; · comparable selling prices; and · property specific discount rates for fair value estimates as necessary. To the extent impairment has occurred, the Company will record an impairment charge calculated as the excess of the carrying value of the asset over its fair value for impairment of investment properties. Based on evaluation, management recorded a loss on impairment of property of $412 during the year ended December 31, 2015. There was no impairment losses during the year ended December 31, 2014 .
Properties Held for Sale	Properties Held for Sale We account for our properties held for sale in accordance with ASC 360, Property, Plant and Equipment (“ASC 360”), which addresses financial accounting and reporting in a period in which a component or group of components of an entity either has been disposed of or is classified as held for sale. In accordance with ASC 360, at such time as a property is held for sale, such property is carried at the lower of (1) its carrying amount or (2) fair value less costs to sell. In addition, a property being held for sale ceases to be depreciated. We classify operating properties as properties held for sale in the period in which all of the following criteria are met: · management, having the authority to approve the action, commits to a plan to sell the asset; · the asset is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets; · an active program to locate a buyer and other actions required to complete the plan to sell the asset has been initiated; · the sale of the asset is probable and the transfer of the asset is expected to qualify for recognition as a completed sale within one year; · the asset is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and · given the actions required to complete the plan to sell the asset, it is unlikely that significant changes to the plan would be made or that the plan would be withdrawn. The results of operations of a component of an entity that either has been disposed of or is classified as held-for-sale under the requirements of ASC 360, shall be reported in discontinued operations in accordance with ASC 205, Presentation of Financial Statements (“ASC 205”) if the following condition is met: · represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. There was one property classified as held for sale at December 31, 2015 , and no properties classified as held for sale at December 31, 2014. See Note 19.
Construction in progress	Construction in Progress The Company capitalizes direct and certain indirect project costs incurred during the development period such as construction, insurance, architectural, legal, interest and other financing costs, and real estate taxes. At such time as the development is considered substantially complete, the capitalization of certain indirect costs such as real estate taxes and interest and financing costs cease and all project-related costs included in construction in process are reclassified to land and building and other improvements.
Cash and Cash Equivalents	Cash and Cash Equivalents We classify highly liquid investments with a maturity of three months or less when purchased as cash equivalents.
Investment in Unconsolidated Affiliates	Investment in Unconsolidated Affiliates We account for unconsolidated affiliates using the equity method of accounting per guidance established under ASC 323, Investments – Equity Method and Joint Ventures (“ASC 323”). The equity method of accounting requires the investment to be initially recorded at cost and subsequently adjusted for our share of equity in the affiliates’ earnings and distributions. We evaluate the carrying amount of the investments for impairment in accordance with ASC 323. Unconsolidated affiliates are reviewed for potential impairment if the carrying amount of the investment exceeds its fair value. An impairment charge is recorded when an impairment is deemed to be other-than-temporary. To determine whether impairment is other-than-temporary, we consider whether we have the ability and intent to hold the investment until the carrying amount is fully recovered. The evaluation of an investment in an affiliate for potential impairment can require our management to exercise significant judgments. No impairment losses were recorded related to the unconsolidated affiliates for the years ended December 31, 2015 and 2014 . We use the equity method to account for investments that qualify as variable interest entities where we are not the primary beneficiary and entities that we do not control or where we do not own a majority of the economic interest but have the ability to exercise significant influence over the operations and financial policies of the investee. We will also use the equity method for investments that do not qualify as variable interest entities and do not meet the control requirements for consolidation, as defined in ASC 810. For a joint venture accounted for under the equity method, our share of net earnings and losses is reflected in income when earned and distributions are credited against our investment in the joint venture as received. In determining whether an investment in a limited liability company or tenant in common is a variable interest entity, we consider: the form of our ownership interest and legal structure; the size of our investment; the financing structure of the entity, including the necessity of subordinated debt; estimates of future cash flows; our and our partner’s ability to participate in the decision making related to acquisitions, dispositions, budgeting and financing on the entity; and obligation to absorb losses and preferential returns. As of December 31, 2015 , we assessed one of our liability liability company arrangements as a variable interest entity where we were not the primary beneficiary. In addition, four of our tenant in common arrangements do not qualify as variable interest entities and do not meet the control requirements for consolidation, as defined in ASC 810. As of December 31, 2015 and 2014 , the unconsolidated affiliates held total assets of $ 32,296 and $ 32,459 and mortgage notes payable of $ 20,421 and $ 20,803 , respectively. The operating partnership owns a 40.26% interest in a single asset limited liability company which owns a 144 unit residential, multifamily apartment complex in Bismarck, North Dakota. The property is encumbered by a first mortgage with a balance at December 31, 2015 and 2014 of $2,259 and $ 2,323 , respectively. We owed $909 and $ 935 of our respective share of the mortgage loan balance as of December 31, 2015 and 2014 , respectively. The Company is jointly and severally liable for the full mortgage balance. The operating partnership is a 50% owner of Grand Forks Marketplace Retail Center through 100% ownership in a limited liability company. Grand Forks Marketplace Retail Center has approximately 183,000 square feet of commercial space in Grand Forks, North Dakota. The property is encumbered by a non-recourse first mortgage with a balance at December 31, 2015 and 2014 of $ 11,079 and $ 11,260 , respectively. We owed $ 5,540 and $ 5,630 for our respective share of the mortgage loan balance as of December 31, 2015 and 2014 , respectively. The Company is jointly and severally liable for the full mortgage balance. The operating partnership owns a 66.67% interest as tenant in common in an office building with approximately 75,000 square feet of commercial rental space in Fargo, North Dakota. The property is encumbered by a first mortgage with a balance at December 31, 2015 and 2014 of $ 7,083 and $ 7,221 , respectively. We owed $ 4,722 and $ 4,814 for our respective share of the mortgage loan balance on December 31, 2015 and 2014 , respectively. The Company is jointly and severally liable for the full mortgage balance. The operating partnership owns an 82.50% interest as a tenant in common in a 61 unit residential, multifamily apartment complex in Fargo, North Dakota. The property was unencumbered at December 31, 2015 and 2014 , respectively . The operating partnership is a 99% owner of Michigan Street Transit Center, LLC (“Transit Center”) through 100% ownership in a limited liability company. The operating partnership has contributed approximately $644 in cash and $1,316 in property contributions to the Transit Center in May and June 2014, respectively. As of December 31, 2015, the property owned by the Transit Center consisted of land previously occupied by a building and parking ramp in Duluth, Minnesota which were both demolished during 2014. The property was unencumbered at December 31, 2015 and 2014 , respectively .
Receivables	Receivables Receivables consist primarily of amounts due for rent and real estate taxes. The receivables are non-interest bearing. The carrying amount of receivables is reduced by an amount that reflects management’s best estimates of the amounts that will not be collected. As of December 31, 2015 and 2014 , management determined no allowance was necessary for uncollectible receivables.
Financing and Lease Costs	Financing and Lease Costs Financing costs have been capitalized and are being amortized over the life of the financing using the effective interest method. Unamortized financing costs are written off when debt is retired before the maturity date and included in amortization expense at that time. Lease costs incurred in connection with new leases have been capitalized and are being amortized over the life of the lease using the straight-line method.
Intangible Assets	Intangible Assets Lease intangibles are a purchase price allocation recorded on property acquisition. The lease intangibles represent the estimated value of in-place leases, tenant relationships and the value of leases with above or below market lease terms. Lease intangibles are amortized over the term of the related lease. The carrying amount of intangible assets is regularly reviewed for indicators of impairments in value. Impairment is recognized only if the carrying amount of the intangible asset is considered to be unrecoverable from its undiscounted cash flows and is measured as the difference between the carrying amount and the estimated fair value of the asset. Based on the review, management determined no impairment charges were necessary at December 31, 2015 and 2014 .
Noncontrolling Interest	Noncontrolling Interest A noncontrolling interest in a subsidiary (minority interest) is in most cases an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements and separate from the parent company’s equity. In addition, consolidated net income is required to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest and the amount of consolidated net income attributable to the parent and the noncontrolling interest are required to be disclosed on the face of the consolidated statements of operations and comprehensive income. Operating Partnership: Interests in the operating partnership held by limited partners are represented by operating partnership units. The operating partnership’s income is allocated to holders of units based upon the ratio of their holdings to the total units outstanding during the period. Capital contributions, distributions, syndication costs, and profits and losses are allocated to noncontrolling interests in accordance with the terms of the operating partnership agreement. Partially Owned Properties: The Company reflects noncontrolling interests in partially owned properties on the balance sheet for the portion of properties consolidated by the Company that are not wholly owned by the Company. The earnings or losses from those properties attributable to the noncontrolling interests are reflected as noncontrolling interest in partially owned properties in the consolidated statement of operations and comprehensive income.
Syndication Costs	Syndication Costs Syndication costs consist of costs paid to attorneys, accountants, and selling agents, related to the raising of capital. Syndication costs are recorded as a reduction to beneficial and noncontrolling interest.
Federal Income Taxes	Federal Income Taxes We have elected to be taxed as a REIT under the Internal Revenue Code, as amended. A REIT calculates taxable income similar to other domestic corporations, with the major difference being a REIT is entitled to a deduction for dividends paid. A REIT is generally required to distribute each year at least 90% of its taxable income. If it chooses to retain the remaining 10% of taxable income, it may do so, but it will be subject to a corporate tax on such income. REIT shareholders are taxed on REIT distributions of ordinary income in the same manner as they are taxed on other corporate distributions. A summary of the tax characterization of the dividends paid to shareholders of the Company’s common stock for the years ended December 31, 2015 and 2014 follows: Tax Year Ended December 31, Dividend % Dividend % 2015 2015 2014 2014 Tax status Ordinary income $ % $ % Capital Gain % % Return of capital % % $ % $ % We intend to continue to qualify as a REIT and, provided we maintain such status, will not be taxed on the portion of the income that is distributed to shareholders. In addition, we intend to distribute all of our taxable income; therefore, no provisions or liabilities for income taxes have been recorded in the financial statements. Sterling conducts its business activity as an Umbrella Partnership Real Estate Investment Trust (“UPREIT”) through its Operating Partnership – Sterling Properties, LLLP. The Operating Partnership is organized as a limited liability limited partnership. Income or loss is allocated to the partners in accordance with the provisions of the Internal Revenue Code 704(b) and 704(c). UPREIT status allows non-recognition of gain by an owner of appreciated real estate if that owner contributes the real estate to a partnership in exchange for a partnership interest. The conversion of a partnership interest to shares of beneficial interest in the REIT will be a taxable event to the limited partner. We follow ASC Topic 740, Income Taxes, to recognize, measure, present and disclose in our consolidated financial statements uncertain tax positions that we have taken or expect to take on a tax return. As of December 31, 2015 and 2014 we did not have any liabilities for uncertain tax positions that we believe should be recognized in our consolidated financial statements. We are no longer subject to Federal and State tax examinations by tax authorities for years before 2012. The operating partnership has elected to record related interest and penalties, if any, as income tax expense on the consolidated statements of operations and other comprehensive income.
Revenue Recognition	Revenue Recognition We recognize revenue in accordance with ASC Topic 605, Revenue Recognition, (“ASC Topic 605”). ASC Topic 605 requires that all four of the following basic criteria be met before revenue is realized or realizable and earned: (1) there is persuasive evidence that an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the seller’s price to the buyer is fixed and determinable; and (4) collectability is reasonably assured. We derive over 95% of our revenues from tenant rents and other tenant-related activities. We lease multifamily units under operating leases with terms of one year or less. Rental income and other property revenues are recorded when due from tenants and recognized monthly as earned pursuant to the terms of the underlying leases. Other property revenues consist primarily of laundry, application and other fees charged to tenants. We lease commercial space primarily under long-term lease agreements. Commercial tenant rents include base rents, expense reimbursements (such as common area maintenance, real estate taxes and utilities), and a straight-line rent adjustment. We record base rents on a straight-line basis. The monthly base rent income according to the terms of our leases is adjusted so that an average monthly rent is recorded for each tenant over the term of its lease. The straight-line rent adjustment increased revenue by $325 and $186 for the years ended December 31, 2015 and 2014 , respectively. The straight-line receivable balance included in receivables on the consolidated balance sheets as of December 31, 2015 and 2014 was $ 2,863 and $ 2,538 , respectively. We receive payments for expense reimbursements from substantially all our multi-tenant commercial tenants throughout the year based on estimates. Differences between estimated recoveries and the final billed amounts, which generally are immaterial, are recognized in the subsequent year.
Earnings per Common Share	Earnings per Common Share Basic earnings per common share is computed by dividing net income available to common shareholders (the “numerator”) by the weighted average number of common shares outstanding (the “denominator”) during the period. Sterling had no dilutive potential common shares as of December 31, 2015 and 2014 , and therefore, basic earnings per common share was equal to diluted earnings per common share for both periods. For the years ended December 31, 2015 and 2014 , Sterling’s denominators for the basic and diluted earnings per common share were approximately 7,223,000 and 5,507,000 , respectively.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”). In accordance with ASU 2014-08, a discontinued operation represents: (i) a component of an entity or group of components that has been disposed of or is classified as held for sale in a single transaction and represents a strategic shift that has or will have a major effect on an entity’s financial results, or (ii) an acquired business that is classified as held for sale on the date of acquisition. A strategic shift could include a disposal of: (i) a separate major line of business, (ii) a separate major geographic area of operations, (iii) a major equity method investment, or (iv) other major parts of an entity. The standard requires prospective application and will be effective for interim and annual periods beginning on or after December 15, 2014 with early adoption permitted. The standard is not applied to components of an entity that were sold or classified as held for sale prior to the adoption of the standard. We have elected to adopt this standard early, effective January 1, 2014, which primarily has the impact of reflecting gains and losses on the sale of operating properties prospectively within continuing operations, and results in not classifying the operations of such operating properties as discontinued operations in all periods presented. Subsequent to our adoption of ASU 2014-08, the sale of real estate that does not meet the definition of a discontinued operation under the standard will be included in gain on sale of operating properties in our consolidated statements of operations and other comprehensive income. In May 2014, the FASB and International Accounting Standards Board issued their final standard on revenue from contracts with customers, which was issued by the FASB as Accounting Standards Update 2014-09, Revenue from Contracts with Customers , or ASU 2014-09. ASU 2014-09, which establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers, supersedes most current GAAP applicable to revenue recognition and converges U.S. and international accounting standards in this area. The core principle of the new guidance is that revenue shall only be recognized when an entity has transferred control of goods or services to a customer and for an amount reflecting the consideration to which the entity expects to be entitled for such exchange. Additionally, lease contracts are specifically excluded form ASU 2014-09. In July 2015, the FASB decided to defer the effective date for annual reporting periods beginning after December 15, 2017. Early adoption is permitted beginning on the original effective date of periods beginning after December 15, 2016. Upon adoption, ASU 2014-09 allows for full retrospective adoption applied to all periods presented or modified retrospective adoption with the cumulative effect of initially applying the standard recognized at the date of initial application. We have not yet determined the effect ASU 2014-09 will have on our consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis ("ASU 2015-02"). This amends ASC 810, Consolidation (ASC "810"), to improve targeted areas of consolidation guidance by simplifying the requirements of consolidation and placing more emphasis on risk of loss when determining a controlling financial interest. ASU 2015-02 is effective for the annual period ending after December 15, 2015, and subsequent interim and annual periods with early adoption permitted. The adoption of ASU 2015-02 is not expected to have a material impact on the Company's consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03 “ Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” . The objective of ASU 2015-03 is to identify, evaluate, and improve areas of generally accepted accounting principles (GAAP) for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. To simplify presentation of debt issuance costs, the amendments in this ASU require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. In August 2015, the FASB issued ASU No. 2015-15, Interest – Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements , which clarifies that absent authoritative guidance in ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the staff of the Securities and Exchange Commission would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. This ASU is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2015. Early adoption is permitted. The adoption of the standard will result in the reclassification of unamortized debt issuance costs related to the Company’s mortgage notes payable from assets, net to reductions in mortgage notes payable within its consolidated balance sheets as of December 31, 2015 and 2014. Other than this reclassification, the adoption of the standard will not have an impact on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments, which requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period, including the cumulative effect of changes in depreciation, amortization, or other income effects, in the reporting period in which the adjustment amounts are determined. Previously, acquirers were required to recognize these adjustments retrospectively. The standard is effective for annual reporting periods beginning after December 15, 2015, and interim periods within those years, with early adoption permitted. The standard will be applied on a prospective basis. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . The guidance requires that lessees will be required to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. The ASU also will require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative information. The standard will take effect for fiscal years, and interim periods within those fiscal years, beginning after Dec. 15, 2018 with earlier application permitted. The Company is still evaluating the impact of ASU No. 2016-02 on its financial position and results of operations. Management does not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material effect on the accompanying Consolidated Financial Statements.
