Jan. 31, 2020
Accounting Policies [Abstract] |
Use of Estimates | USE OF ESTIMATES The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Trust’s operations are affected by numerous factors, including the economy, competition in the hotel industry and the effect of the economy on the travel and hospitality industries. The Trust cannot predict if any of the above items will have a significant impact in the future, nor can it predict what impact, if any, the occurrence of these or other events might have on the Trust’s operations and cash flows. Significant estimates and assumptions made by management include, but are not limited to, the estimated useful lives, the recoverability of long-lived assets, the fair values of the long-lived assets, the fair value of right of use assets and lease liabilities, and the collectability of Notes Receivable.
Property, Plant and Equipment and Hotel Properties | PROPERTY, PLANT AND EQUIPMENT AND HOTEL PROPERTIES Furniture, fixtures, building improvements and hotel properties are stated at cost and depreciated using the straight-line method over estimated lives ranging up to 40 years for buildings and 3 to 10 years for furniture and equipment. Management applies guidance ASC 360-10-35, to determine when it is required to test an asset for recoverability of its carrying value and whether, or not, an impairment exists. Under ASC 360-10-35, the Trust is required to test a long-lived asset for impairment when there is an indicator of impairment. Impairment indicators may include, but are not limited to, a drop in the performance of a long-lived asset, a decline in the hospitality industry or a decline in the economy. If an indicator of potential impairment is present, then an assessment is performed of whether the carrying amount of an asset exceeds its estimated undiscounted future cash flows over its estimated remaining life. If the estimated undiscounted future cash flows over the asset’s estimated remaining life are greater than the asset’s carrying value, no impairment is recognized; however, if the carrying value of the asset exceeds the estimated undiscounted future cash flows, then the Trust would recognize an impairment expense to the extent the asset’s carrying value exceeds its fair value, if any. The estimated future cash flows are based upon, among other things, assumptions about expected future operating performance, and may differ from actual cash flows. Long-lived assets evaluated for impairment are analyzed on a property-specific basis independent of the cash flows of other groups of assets. Evaluation of future cash flows is based on historical experience and other factors, including certain economic conditions and committed future bookings. Management impaired these assets during the fiscal year 2018, and has determined that no further impairment is required of long-lived assets for the fiscal periods ended January 31, 2019 and January 31, 2020.
Business Combinations | BUSINESS COMBINATIONS The Trust accounts for business combinations by recognizing the assets acquired, liabilities assumed, contractual contingencies, and contingent consideration at their fair values on the acquisition date. The final purchase price may be adjusted up to one year from the date of the acquisition. Identifying the fair value of the tangible and intangible assets and liabilities requires the use of estimates by management and was based upon currently available data. The Trust allocates the excess of purchase price over the identifiable intangible and net tangible assets to goodwill. Such goodwill is not deductible for tax purposes and represents the value placed on entering new markets and expanding market share (see Note 8). Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates or actual results. Additionally, any change in the fair value of the acquisition-related contingent consideration subsequent to the acquisition date, included changes from events after the acquisition date, such as changes in our estimate of relevant revenue or other targets, will be recognized in earnings in the period of the estimated fair value change. A change in fair value of the acquisition-related contingent consideration or the occurrence of events that cause results to differ from our estimates or assumptions could have a material effect on the consolidated statements of operations, financial position and cash flows in the period of the change in the estimate.
Goodwill | GOODWILL The Trust will test goodwill for impairment annually, as applicable, or whenever events or changes in circumstances indicate an impairment may have occurred, by comparing its reporting unit’s carrying value to its implied fair value. Impairment may result from, among other things, deterioration in the performance of the acquired business, adverse market conditions, adverse changes in applicable laws or regulations and a variety of other circumstances. If the Trust determines that an impairment has occurred, it is required to record a write-down of the carrying value and charge the impairment as an operating expense in the period the determination is made. In evaluating the recoverability of the carrying value of goodwill, the Trust must make assumptions regarding estimated future cash flows and other factors to determine the fair value of the acquired assets. Changes in strategy or market conditions could significantly impact those judgements in the future and require an adjustment to the recorded balances.
Cash and Cash Equivalents | CASH AND CASH EQUIVALENTS The Trust considers all highly liquid short-term investments with maturities of three months or less at the time of purchase to be cash equivalents. The Trust believes it places its cash and cash equivalents only with high credit quality financial institutions, although these balances may periodically exceed federally insured limits.
Revenue Recognition | REVENUE RECOGNITION Hotel and Operations ASU 2014-09 (Topic 606), “Revenue from Contracts with Customers” is effective for reporting periods after January 1, 2018. ASU 2014-09 requires entities to recognize revenue through the application of a five-step model, which includes identification of the contract, identification of the performance obligations, determination of the transaction price, allocation of the transaction price to the performance obligations and recognition of revenue as the entity satisfies the performance obligations. Revenues are primarily derived from the sources below and are recognized as services are rendered and when collectability is reasonably assured. Amounts received in advance of revenue recognition are considered deferred liabilities, and are generally not significant. Revenues primarily consist of room rentals, food and beverage sales, management and trademark fees and other miscellaneous revenues from our properties. Revenues are recorded when rooms are occupied and when food and beverage sales are delivered. Management and trademark fees from non-affiliated hotels include a monthly accounting fee and a percentage of hotel room revenues for managing the daily operations of the Hotels and the one hotel owned by affiliates of Mr. Wirth. We are required to collect certain taxes and fees from customers on behalf of government agencies and remit these back to the applicable governmental agencies on a periodic basis. We have a legal obligation to act as a collection agent. We do not retain these taxes and fees and, therefore, they are not included in revenues. We record a liability when the amounts are collected and relieve the liability when payments are made to the applicable taxing authority or other appropriate governmental agency.
Accounts Receivables and Allowance for Doubtful Accounts | ACCOUNTS RECEIVABLES AND ALLOWANCE FOR DOUBTFUL ACCOUNTS Accounts receivable are carried at original amounts billed less an estimate made for doubtful accounts based on a review of outstanding amounts on a quarterly basis. Management generally records an allowance for doubtful accounts for 50% of balances over 90 days and 100% of balances over 120 days. Accounts receivable are written off when collection efforts have been exhausted and they are deemed uncollectible. Recoveries, if any, of receivables previously written off are recorded when received. The Trust does not charge interest on accounts receivable balances and these receivables are unsecured. The following is a reconciliation of the allowance for doubtful accounts for the fiscal years ended January 31, 2020 and 2019.
Fiscal Year |  | Balance at the Beginning of Period |  |  | Discontinued Operations Adjustment |  |  | Charged to Expense |  |  | Deductions |  |  | Balance at the End of Period |
2020 |  | $ | (5,943 | ) |  | $ | - |  |  | $ | (13,223 | ) |  | $ | 4,377 |  |  | $ | (14,789 | )

Stock-based Compensation | STOCK-BASED COMPENSATION The Trust has an employee equity incentive plan, which is described more fully in Note 24 - “Share-Based Payments.” For fiscal years 2020 and 2019, the Trust has paid the annual fees due to its Trustees by issuing Shares of Beneficial Interest out of its authorized but unissued Shares. Upon issuance, the Trust recognizes the shares as outstanding. The Trust recognizes expense related to the issuance based on the fair value of the shares upon the date of the restricted share grant and amortizes the expense equally over the period during which the shares vest to the Trustees. During fiscal year 2020, the Trust granted restricted stock awards of 18,000 Shares to members of the Board of Trustees, all of which vested in fiscal year 2020 resulting in stock-based compensation of $32,400. During fiscal year 2019, the Trust granted restricted stock awards of 18,000 Shares to members of the Board of Trustees, all of which vested in fiscal year 2019 resulting in stock-based compensation of $32,400. The following table summarizes restricted share activity during fiscal years 2019 and 2020.

Treasury Stock | TREASURY STOCK Treasury stock is carried at cost, including any brokerage commissions paid to repurchase the shares. Any shares issued from treasury stock are removed at cost, with the difference between cost and fair value at the time of issuance recorded against Shares of Beneficial Interest.
Income Taxes | INCOME TAXES The Trust is subject to federal and state corporate income taxes, and accounts for deferred taxes utilizing an asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when it is determined to be more likely than not that some portion, or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment (see Note 18).
Dividends and Distributions | DIVIDENDS AND DISTRIBUTIONS In fiscal years 2020 and 2019, the Trust paid a dividend of $0.01 per share at end of the second fiscal quarter and at the end of the fourth fiscal quarter for a total dividend of $0.02 for the fiscal year in the amounts of $191,924 and $195,575, respectively. The Trust’s ability to pay dividends is largely dependent upon the operations of the Hotels.
Non-controlling Interest | NON-CONTROLLING INTEREST Non-controlling interest in the Trust represents the limited partners’ proportionate share of the capital and earnings of the Partnership. Income or loss is allocated to the non-controlling interest based on a weighted average ownership percentage in the entities throughout the period, and capital is allocated based on the ownership percentage at year-end. Any difference between the weighted average and point-in-time allocations is presented as a reallocation of non-controlling interest as a component of shareholders’ equity.
Income (Loss) Per Share | INCOME (LOSS) PER SHARE Basic and diluted income (loss) per Share of Beneficial Interest is computed based on the weighted-average number of Shares of Beneficial Interest and potentially dilutive securities outstanding during the period. Dilutive securities are limited to the Class A and Class B units of the Partnership, which are convertible into 3,024,038 Shares of the Beneficial Interest, as discussed in Note 1. For the fiscal years ended January 31, 2020 and 2019, there were Class A and Class B Partnership units outstanding, which are convertible into Shares of Beneficial Interest of the Trust. Assuming conversion at the beginning of each period, the aggregate weighted-average of these Shares of Beneficial Interest would have been 3,185,746 and 3,473,085 in addition to the basic shares outstanding for fiscal years 2020 and 2019, respectively. These Shares of Beneficial Interest issuable upon conversion of the Class A and Class B Partnership units were dilutive during fiscal 2019 and are included in the calculation of diluted earnings per share for that year below.
|  | For the Twelve Months Ended |
|  | January 31, 2019 |
Net (Loss) Income attributable to controlling interest |  | $ | 1,419,701 |
Plus: Net Income attributable to non-controlling interests |  |  | 9,686,182 |
Net (Loss) Income |  | $ | 11,105,883 |
Weighted average common shares outstanding |  |  | 9,283,081 |
Plus: Weighted average incremental shares resulting from unit conversion |  |  | 3,153,475 |
Weighted average common shares outstanding after unit conversion |  |  | 12,436,556 |
Diluted Income Per Share |  | $ | 0.89 |
Segment Reporting | SEGMENT REPORTING As a result of the sale of IBC (see Note 25), the Chief Operating Decision Maker (“CODM”), Mr. Wirth, CEO of the Trust, has determined that the Trust operations are comprised of one reportable segment, Hotel Operations & Corporate Overhead (continuing operations) segment that has ownership interest in two hotel properties with an aggregate of 270 suites in Arizona and New Mexico. Prior to the sale of IBC, the Trust had previously determined that its operations were comprised of two reportable segments, a Hotel Operations & Corporate Overhead segment, and the IBC Hospitality segment serving 2,000 unrelated hotel properties. In connection with the sale of IBC, the historical financial information presented in this Form 10-K reflects this change with IBC being reported as discontinued operation. The Trust has chosen to focus its hotel investments in the southwest region of the United States. The CODM does not review assets by geographical region; therefore, no income statement or balance sheet information by geographical region is provided.
Advertising Costs | ADVERTISING COSTS Amounts incurred for advertising costs are expensed as incurred. Advertising expense totaled approximately $344,000 and $581,000 for the years ended January 31, 2020 and 2019, respectively.
Concentration of Credit Risk | CONCENTRATION OF CREDIT RISK Credit risk is the risk of an unexpected loss if a third party to a financial instrument fails to meet its contractual obligations. Financial instruments that potentially subject the Trust to a concentration of credit risk consist primarily of cash and cash equivalents. Management’s assessment of the Trust’s credit risk for cash and cash equivalents is low as cash and cash equivalents are held in financial institutions believed to be credit worthy. The Trust limits its exposure to credit loss by placing its cash with major financial institutions and invests only in short-term obligations. While the Trust is exposed to credit losses due to the non-performance of its counterparties, the Trust considers the risk of this remote. The Trust estimates its maximum credit risk for accounts receivable at the amount recorded on the balance sheet.
Fair Value of Financial Instruments | FAIR VALUE OF FINANCIAL INSTRUMENTS For disclosure purposes, fair value is determined by using available market information and appropriate valuation methodologies. Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability. The fair value framework specifies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation technique are observable or unobservable. The fair value hierarchy levels are as follows:
| ● | Level 1 – Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.
| ● | Level 2 – Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and / or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are level 2 valuation techniques.
| ● | Level 3 – Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect a company’s own judgments about the assumptions that market participants would use in pricing an asset or liability.
The Trust has no assets or liabilities that are carried at fair value on a recurring basis and had no fair value re-measurements during the years ended January 31, 2020 and 2019. Due to their short maturities, the carrying value of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value and are considered level 1 inputs. The fair value of mortgage notes payable, notes payable to banks and notes and advances payable to related parties is estimated by using the current rates which would be available for similar loans having the same remaining maturities and are based on level 3 inputs.
