AEI Income & Growth Fund XXII Limited Partnership ("Partnership") was formed to acquire and lease commercial properties to operating tenants.  The Partnership's operations are managed by AEI Fund Management XXI, Inc. ("AFM"), the Managing General Partner.  Robert P. Johnson, the President and sole director of AFM, serves as the Individual General Partner.  AFM is a wholly owned subsidiary of AEI Capital Corporation of which Mr. Johnson is the majority shareholder.  AEI Fund Management, Inc. ("AEI"), an affiliate of AFM, performs the administrative and operating functions for the Partnership.

The terms of the Partnership offering called for a subscription price of $1,000 per Limited Partnership Unit, payable on acceptance of the offer.  The Partnership commenced operations on May 1, 1997 when minimum subscriptions of 1,500 Limited Partnership Units ($1,500,000) were accepted.  The offering terminated January 9, 1999 when the extended offering period expired.  The Partnership received subscriptions for 16,917.222 Limited Partnership Units.  Under the terms of the Limited Partnership Agreement, the Limited Partners and General Partners contributed funds of $16,917,222 and $1,000, respectively.

During operations, any Net Cash Flow, as defined, which the General Partners determine to distribute will be distributed 97% to the Limited Partners and 3% to the General Partners.  Distributions to Limited Partners will be made pro rata by Units.

Any Net Proceeds of Sale, as defined, from the sale or financing of properties which the General Partners determine to distribute will, after provisions for debts and reserves, be paid in the following manner: (i) first, 99% to the Limited Partners and 1% to the General Partners until the Limited Partners receive an amount equal to: (a) their Adjusted Capital Contribution plus (b) an amount equal to 9% of their Adjusted Capital Contribution per annum, cumulative but not compounded, to the extent not previously distributed from Net Cash Flow; (ii) any remaining balance will be distributed 90% to the Limited Partners and 10% to the General Partners.  Distributions to the Limited Partners will be made pro rata by Units.

For tax purposes, profits from operations, other than profits attributable to the sale, exchange, financing, refinancing or other disposition of property, will be allocated first in the same ratio in which, and to the extent, Net Cash Flow is distributed to the Partners for such year.  Any additional profits will be allocated in the same ratio as the last dollar of Net Cash Flow is distributed.  Net losses from operations will be allocated 99% to the Limited Partners and 1% to the General Partners.

For tax purposes, profits arising from the sale, financing, or other disposition of property will be allocated in accordance with the Partnership Agreement as follows: (i) first, to those partners with deficit balances in their capital accounts in an amount equal to the sum of such deficit balances; (ii) second, 99% to the Limited Partners and 1% to the General Partners until the aggregate balance in the Limited Partners' capital accounts equals the sum of the Limited Partners' Adjusted Capital Contributions plus an amount equal to 9% of their Adjusted Capital Contributions per annum, cumulative but not compounded, to the extent not previously allocated; (iii) third, the balance of any remaining gain will then be allocated 90% to the Limited Partners and 10% to the General Partners.  Losses will be allocated 98% to the Limited Partners and 2% to the General Partners.

The General Partners are not required to currently fund a deficit capital balance.  Upon liquidation of the Partnership or withdrawal by a General Partner, the General Partners will contribute to the Partnership an amount equal to the lesser of the deficit balances in their capital accounts or 1% of total Limited Partners' and General Partners' capital contributions.

In May 2015, the Managing General Partner mailed a Consent Statement (Proxy) seeking the consent of the Limited Partners to continue the Partnership for an additional 60 months or to initiate the final disposition, liquidation and distribution of all of the Partnership's properties and assets.  Approval of either proposal required the affirmative vote of holders of a majority of the outstanding units.  On June 17, 2015, the votes were counted and neither proposal received the required majority vote.  As a result, the Partnership will not liquidate and will continue in operation until the Limited Partners vote to authorize the sale of all of the Partnership's properties or December 31, 2046, as stated in the Limited Partnership Agreement. However, in approximately five years, the Managing General Partner expects to again submit the question to liquidate to a vote by the Limited Partners.

In January 2017, the FASB issued ASU 2017-01, which clarifies the definition of a business by adding guidance to assist entities in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses.  The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods, with early adoption permitted, and is required to be applied prospectively to any transactions occurring within the period of adoption.  We expect the new standard will result in all of our real estate acquisitions being considered asset acquisitions, whereby substantially all acquisition costs related to discontinued operations inour real estate acquisitions will be capitalized.  Prior to the prior year's financial statementsadoption of the new standard, all of our real estate acquisitions completed after January 1, 2009, were considered acquisitions of businesses, whereby all acquisition-related costs were expensed as incurred.  During 2018, the Partnership has adopted the accounting pronouncement effective January 1, 2018, and applied this guidance prospectively.  The adoption did not have been reclassified to conform to 2017 presentation.  These reclassifications had noa material effect on Partners' capital, net income or cash flows.its financial statements.

AEI Fund Management, Inc. performs the administrative and operating functions for the Partnership.  The payable to AEI Fund Management represents the balance due for those services.  This balance is non-interest bearing and unsecured and is to be paid in the normal course of business.

For the three months ended March 31, 20172018 and 2016,2017, the Partnership declared distributions of $144,948$142,476 and $146,803,$144,948, respectively.  The Limited Partners received distributions of $140,600$138,201 and $142,399$140,600 and the General Partners received distributions of $4,348$4,275 and $4,404$4,348 for the periods, respectively.  The Limited Partners' distributions represented $10.04$10.13 and $9.92$10.04 per Limited Partnership Unit outstanding using 14,00213,641 and 14,35514,002 weighted average Units in 20172018 and 2016,2017, respectively.  The distributions represented $5.00$4.51 and $5.22$5.00 per Unit of Net Income and $5.04$5.62 and $4.70$5.04 per Unit of return of capital in 20172018 and 2016,2017, respectively.

As of March 31, 20172018 and December 31, 2016,2017, the Partnership had no assets or liabilities measured at fair value on a recurring basis or nonrecurring basis.

This section contains "forward-looking statements" which represent management's expectations or beliefs concerning future events, including statements regarding anticipated application of cash, expected returns from rental income, growth in revenue, the sufficiency of cash to meet operating expenses, rates of distribution, and other matters.  These, and other forward-looking statements, should be evaluated in the context of a number of factors that may affect the Partnership's financial condition and results of operations, including the following:

The Partnership's financial statements have been prepared in accordance with US GAAP.  Preparing the financial statements requires management to use judgment in the application of these accounting policies, including making estimates and assumptions.  These judgments will affect the reported amounts of the Partnership's assets and liabilities and the disclosure of contingent assets and liabilities as of the dates of the financial statements and will affect the reported amounts of revenue and expenses during the reporting periods.  It is possible that the carrying amount of the Partnership's assets and liabilities, or the results of reported operations, will be affected if management's estimates or assumptions prove inaccurate.

Management of the Partnership evaluates the following accounting estimates on an ongoing basis, and has discussed the development and selection of these estimates and the management discussion and analysis disclosures regarding them with the managing partner of the Partnership.

Upon acquisition of real properties, the Partnership records them in the financial statements at cost.  The purchase price is allocated to tangible assets, consisting of land and building, and to identified intangible assets and liabilities, which may include the value of above market and below market leases and the value of in-place leases.  The allocation of the purchase price is based upon the fair value of each component of the property.  Although independent appraisals may be used to assist in the determination of fair value, in many cases these values will be based upon management's assessment of each property, the selling prices of comparable properties and the discounted value of cash flows from the asset.

The fair values of above market and below market in-place leases will be recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) an estimate of fair market lease rates for the corresponding in-place leases measured over a period equal to the non-cancelable term of the lease including any bargain renewal periods.  The above market and below market lease values will be capitalized as intangible lease assets or liabilities.  Above market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases.  Below market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases, including any bargain renewal periods.  If a lease were to be terminated prior to its stated expiration, all unamortized amounts of above market and below market in-place lease values relating to that lease would be recorded as an adjustment to rental income.

The fair values of in-place leases will include estimated direct costs associated with obtaining a new tenant, and opportunity costs associated with lost rentals which are avoided by acquiring an in-place lease.  Direct costs associated with obtaining a new tenant may include commissions, tenant improvements, and other direct costs and are estimated, in part, by management's consideration of current market costs to execute a similar lease.  These direct costs will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases.  The value of opportunity costs will be calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease.  These intangibles will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases.  If a lease were to be terminated prior to its stated expiration, all unamortized amounts of in-place lease assets relating to that lease would be expensed.

The determination of the fair values of the assets and liabilities acquired will require the use of significant assumptions with regard to the current market rental rates, rental growth rates, discount and capitalization rates, interest rates and other variables.  If management's estimates or assumptions prove inaccurate, the result would be an inaccurate allocation of purchase price, which could impact the amount of reported net income.

Properties are carried at original cost, less accumulated depreciation and amortization.  The Partnership tests long-lived assets for recoverability when events or changes in circumstances indicate that the carrying value may not be recoverable.  For properties the Partnership will hold and operate, management determines whether impairment has occurred by comparing the property's probability-weighted future undiscounted cash flows to its current carrying value.  For properties held for sale, management determines whether impairment has occurred by comparing the property's estimated fair value less cost to sell to its current carrying value.  If the carrying value is greater than the net realizable value, an impairment loss is recorded to reduce the carrying value of the property to its net realizable value.  Changes in these assumptions or analysis may cause material changes in the carrying value of the properties.

AEI Fund Management, Inc. allocates expenses to each of the funds they manage primarily on the basis of the number of hours devoted by their employees to each fund's affairs.  They also allocate expenses at the end of each month that are not directly related to a fund's operations based upon the number of investors in the fund and the fund's capitalization relative to other funds they manage.  The Partnership reimburses these expenses subject to detailed limitations contained in the Partnership Agreement.

For the three months ended March 31, 20172018 and 2016,2017, the Partnership recognized rental income of $179,431 and $188,101, and $192,877, respectively.  RentalIn 2018, rental income decreased in 2017, when compared to 2016, due to payments received from a prior tenant's bankruptcy plan in 2016.rent decrease related to the Advance Auto Parts store, as discussed below.  This decrease was partially offset by rent increases on two properties.  Based on the scheduled rent for the properties as of April 30, 2017,2018, the Partnership expects to recognize rental income from continuing operations of approximately $755,000$718,000 in 2017.

For the three months ended March 31, 20172018 and 2016,2017, the Partnership incurred Partnership administration expenses from affiliated parties of $29,609$28,237 and $30,046,$29,609, respectively.  These administration expenses include costs associated with the management of the properties, processing distributions, reporting requirements and communicating with the Limited Partners.  During the same periods, the Partnership incurred Partnership administration and property management expenses from unrelated parties of $9,985$11,302 and $9,452,$9,985, respectively.  These expenses represent direct payments to third parties for legal and filing fees, direct administrative costs, outside audit costs, taxes, insurance and other property costs.

For the three months ended March 31, 20172018 and 2016,2017, the Partnership recognized interest income of $668 and $797, and $948, respectively.

Management believes inflation has not significantly affected income from operations.  Leases may contain rent increases, based on the increase in the Consumer Price Index over a specified period, which will result in an increase in rental income over the term of the leases.  Inflation also may cause the real estate to appreciate in value.  However, inflation and changing prices may have an adverse impact on the operating margins of the properties' tenants, which could impair their ability to pay rent and subsequently reduce the Net Cash Flow available for distributions.

During the three months ended March 31, 20172018 and 2016,2017, the Partnership's cash balances increased $43,933$24,666 and $62,153,$43,933, respectively, as a result of cash generated from operating activities in excess of distributions paid to the Partners.

Net cash provided by operating activities decreased from $208,956$188,881 in 20162017 to $188,881in 2017$167,142 in 2018 as a result of a decrease in total rental and interest income in 2017, an increase in Partnership administration and property management expenses in 20172018 and net timing differences in the collection of payments from the tenants and the payment of expenses.

The Partnership's primary use of cash flow, other than investment in real estate, is distribution payments to Partners and cash used to repurchase Units.  The Partnership declares its regular quarterly distributions before the end of each quarter and pays the distribution in the first week after the end of each quarter.  The Partnership attempts to maintain a stable distribution rate from quarter to quarter.  The Partnership may repurchase tendered Units on April 1st and October 1st of each year subject to limitations.

For the three months ended March 31, 20172018 and 2016,2017, the Partnership declared distributions of $144,948$142,476 and $146,803,$144,948, respectively.  Pursuant to the Partnership Agreement, distributions of Net Cash Flow were allocated 97% to the Limited Partners and 3% to the General Partners.  Distributions of Net Proceeds of Sale were allocated 99% to the Limited Partners and 1% to the General Partners.  The Limited Partners received distributions of $140,600$138,201 and $142,399$140,600 and the General Partners received distributions of $4,348$4,275 and $4,404$4,348 for the periods, respectively.

The Partnership may repurchase Units from Limited Partners who have tendered their Units to the Partnership.  Such Units may be acquired at a discount.  The Partnership will not be obligated to purchase in any year any number of Units that, when aggregated with all other transfers of Units that have occurred since the beginning of the same calendar year (excluding Permitted Transfers as defined in the Partnership Agreement), would exceed 5% of the total number of Units outstanding on January 1 of such year.  In no event shall the Partnership be obligated to purchase Units if, in the sole discretion of the Managing General Partner, such purchase would impair the capital or operation of the Partnership.  During the three months ended March 31, 20172018 and 2016,2017, the Partnership did not repurchase any Units from the Limited Partners.

The continuing rent payments from the properties, together with cash generated from property sales, should be adequate to fund continuing distributions and meet other Partnership obligations on both a short-term and long-term basis.

As of March 31, 20172018 and December 31, 2016,2017, the Partnership had no material off-balance sheet arrangements that had or are reasonably likely to have current or future effects on its financial condition, results of operations, liquidity or capital resources.
