judgments that may or may not prove to be correct and may also be based on limited information readily available at that time. In general, we expect that any estimates of value or interim appraisals will be performed as soon as possible after a determination by the Advisor that a material change has occurred and the financial effects of such change are quantifiable by the independent valuation advisor. However, rapidly changing market conditions or material events may not be immediately reflected in our NAV. The resulting potential disparity in our NAV may inure to the benefit of stockholders whose shares are repurchased or new purchasers of our common stock, depending on whether our published NAV per share for such class is overstated or understated.
In accordance with the valuation guidelines, our fund administrator calculates our NAV per share for each class of our common stock as of the last calendar day of each month, using a process that reflects several components (each as described above), including the estimated fair value of (1) each of our properties based upon individual appraisal reports provided periodically by third-party independent valuation firms and reviewed by our independent valuation advisor, (2) our real estate-related assets for which third-party market quotes are available, (3) our other real estate-related assets, if any, and (4) our other assets and liabilities. The NAV per share for our share classes may differ because stockholder servicing fees allocable to a specific class of shares are only included in the NAV calculation for that class and the advisory fee allocable to the Class N shares differs from the advisory fee allocable to the other share classes.
At the end of each month, before taking into consideration additional issuances of shares of capital stock, share repurchases or class-specific expense accruals for that month, any change in our aggregate NAV (whether an increase or decrease) is allocated among each class of shares based on each class’s relative percentage of the previous aggregate NAV plus issuances of shares that were effective on the first calendar day of such month. The NAV calculation is available generally within 15 calendar days after the end of the applicable month. Changes in our monthly NAV include, without limitation, accruals of our net portfolio income, interest expense, the advisory fee, distributions, unrealized/realized gains and losses on assets, any applicable organization and offering costs and any expense reimbursements. Changes in our monthly NAV also includes material non-recurring events, such as capital expenditures and material property acquisitions and dispositions occurring during the month. On an ongoing basis, the Advisor will adjust the accruals to reflect actual operating results and the outstanding receivable, payable and other account balances resulting from the accumulation of monthly accruals for which financial information is available.
We reimburse the Advisor for any organization and offering expenses that it incurs on our behalf as and when incurred. These expenses include legal, accounting, printing, mailing and filing fees and expenses, due diligence expenses of participating broker-dealers supported by detailed and itemized invoices, costs in connection with preparing sales materials, design and website expenses, fees and expenses of our transfer agent, fees to attend retail seminars sponsored by participating broker-dealers and reimbursements for customary travel, lodging, and meals, but exclude upfront selling commissions, dealer manager fees and stockholder servicing fees. After the termination of each public offering, the Advisor has agreed to reimburse us to the extent that the organization and offering expenses that we incur with respect to that offering exceed 15% of the gross proceeds from such offering. In connection with our initial public offering, the Advisor advanced $4.6 million of our organization and offering expenses on our behalf from our inception through December 2018. We will reimburse the Advisor for these organization and offering expenses ratably over the 60 months following the earlier of the date our NAV first reaches $1 billion or January 31, 2023. Our NAV reached $1 billion in October 2021. Such expenses will not be deducted from our NAV until they are payable to the Advisor.
