As of June 30, 2022, our top five customers represented 15.5% of our total annualized base rent of our portfolio, our top ten customers represented 20.7% of our total annualized base rent of our portfolio and there was one customer that individually represented more than 5.0% of our total annualized base rent of our portfolio. Our results of operations are currently substantially dependent on our top customers, and any downturn in their businesses could have a material adverse effect on our operations. In addition, certain of our properties are occupied by a single customer, and as a result, the success of those properties depends on the financial stability of that customer. Adverse impacts to such customers, businesses or operators, including as a result of changes in market or economic conditions, natural disasters, outbreaks of an infectious disease, pandemic or any other serious public health concern, political events or other factors that may impact the operation of these properties, may have negative effects on our business and financial results. As a result, some of our customers have been, and may in the future be, required to suspend operations at our properties for what could be an extended period of time. Further, if such customers default under their leases, we may not be able to promptly enter into a new lease or operating arrangement for such properties, rental rates or other terms under any new leases or operating arrangement may be less favorable than the terms of the current lease or operating arrangement or we may be required to make capital improvements to such properties for a new customer, any of which could adversely impact our operating results.
Changes in global, national, regional or local economic, demographic, political, real estate or capital market conditions, including periods of generally deteriorating real estate industry fundamentals, may adversely affect our results of operations and returns to our stockholders.
We are subject to risks generally incident to the ownership of property, including changes in global, national, regional or local economic, demographic, political, real estate, or capital market conditions and other factors particular to the locations of the respective property investments. We are unable to predict future changes in these market conditions. For example, an economic downturn or a rise in interest rates could make it more difficult for us to lease properties or dispose of them and cause rental rates or future contractual rate increases to fall, which may adversely and materially affect our net operating income and NAV. In addition, rising interest rates could also increase capitalization rates and make alternative interest bearing and other investments more attractive and, therefore, potentially lower the relative value of our existing real estate investments and our NAV. These macroeconomic factors may cause investors to become reluctant to purchase our shares or existing investors to redeem their shares, curtailing our ability to purchase new accretive real estate investments that satisfy our investment criteria.
In addition, we believe the risks associated with our business and the value of our properties are more severe during periods of economic slowdown or recession if these periods are accompanied by deteriorating fundamentals and declining values in the real estate industry. Because debt-related investments we may make in the future might consist of mortgages secured by real property, these same conditions could also adversely affect the underlying borrowers and collateral of assets that we own. Declining real estate values and deteriorating real estate fundamentals would also likely reduce the level of new mortgage loan originations, since borrowers often use increases in the value of their existing properties to support the purchase of, or investment in, additional properties. Furthermore, borrowers may not be able to pay principal and interest on such loans. Declining real estate values would also significantly increase the likelihood that we incur losses on our debt investments in the event of a default because the value of the collateral may be insufficient to cover some or all of the basis in the investment.
In the future, we may record impairments of real properties, significant other-than-temporary impairment charges related to our real estate-related securities holdings, and provisions for losses on our debt-related investments, if any. To the extent that there is a general economic slowdown or real estate fundamentals deteriorate, such factors could have a significant and adverse impact on our revenues, results from operations, value of our properties, financial condition, liquidity, overall business prospects and ultimately our ability to make distributions to our stockholders.

Share Redemption Program
We expect that there will be no regular secondary trading market for shares of our common stock. While our stockholders should view their investment as long term with limited liquidity, we have adopted a share redemption program applicable to all shares of our common stock, whereby stockholders may receive the benefit of limited liquidity by presenting for redemption to us all or any portion of those shares in accordance with the procedures and subject to certain conditions and limitations. All references herein to classes of shares of our common stock do not include the OP Units issued by our Operating Partnership, unless the context otherwise requires.
While stockholders may request on a monthly basis that we redeem all or any portion of their shares pursuant to our share redemption program, we are not obligated to redeem any shares and may choose to redeem only some, or even none, of the shares that have been requested to be redeemed in any particular month, in our discretion. In addition, our ability to fulfill redemption requests is subject to a number of limitations. As a result, share redemptions may not be available each month. Under our share redemption program, to the
