These factors include the time and expense to resolve all obligations, liabilities and claims, including contingent liabilities and claims that are not yet asserted but may be made in the future. Among other things, delays in resolving pending or threatened litigation or other asserted claims, currently unasserted claims that arise in the future and other factors could result in a reduction in future distributions to Unit Holders in ALP and could extend the time, and significantly increase the cost, to complete the liquidation, winding up and termination of ALP. While ALP intends to defend against asserted claims where appropriate, it is currently not possible to identify or assess any defenses or counterclaims that may be available to ALP, or the magnitude of any claims that may be asserted. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported or disclosed in the financial statements and accompanying notes.

Indemnification of Certain Persons Under certain circumstances, ALP indemnifies the Administrator and certain other persons performing services on behalf of ALP for liability they may incur arising out of the indemnified persons' activities conducted on behalf of ALP. There is no limitation on the maximum potential payments under these indemnification obligations, and, due to the number and variety of events and circumstances under which these indemnification obligations could arise, ALP is not able to estimate such maximum potential payments. However, historically ALP has not made payments in material amounts under such indemnification obligations, and no amount has been accrued in the accompanying financial statements for these indemnification obligations of ALP.

Summary of Significant Accounting Policies

Readers of this quarterly report should refer to the audited financial statements for the fiscal year ended December 31, 2017, which are included in ALP’s 2017 Annual Report on Form 10-K (File No. 0-16976) filed on March 20, 2018, as certain footnote disclosures which would substantially duplicate those contained in such audited financial statements, and which are required by U.S. generally accepted accounting principles for complete financial statements, have been omitted from this report. Capitalized terms used but not defined in this quarterly report have the same meanings as in the 2017 Annual Report.

The unaudited consolidated condensed financial statements and notes have been prepared on the same basis as the annual audited financial statements and include all adjustments, which are in the opinion of management, necessary to present a fair statement of ALP's financial position, results of operations and of cash flows as of and for the interim periods presented. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the year ending December 31, 2018 or for any other interim period or for any other future year.

The carrying amount of ALP’s financial instruments, principally cash and cash equivalents, other assets, accounts payable and accrued expenses approximate fair value at March 31, 2018 and December 31, 2017.

Basis of Presentation

The Financial Accounting Standards Board (“FASB”) issued accounting guidance on when and how an entity should apply the liquidation basis of accounting. Under the guidance, liquidation basis of accounting should only be used when liquidation is imminent, as defined in the guidance. Liquidation basis of accounting requires an entity to measure its assets at the estimated amount of cash or other consideration that it expects to collect and its liabilities at the amount otherwise prescribed under U.S. GAAP. ALP has assessed the guidance and concluded that the liquidation of ALP is not imminent, as defined in the guidance. ALP will continue to monitor whether liquidation is imminent and, thereby, evaluate whether liquidation basis of accounting is required.

Until the ultimate completion of the liquidation, winding up and termination of ALP, it is currently anticipated that ALP will retain all or substantially all of its funds in reserve to provide for the payment of, the defense against, or other satisfaction or resolution of obligations, liabilities (including contingent liabilities) and current and possible future claims, and pending and possible future litigation. It is not possible at this time to estimate the amount of time or money that it will take to effect ALP's liquidation, winding up and termination. That portion, if any, of the funds held in reserve that are not ultimately used to pay, defend or otherwise resolve or satisfy obligations, liabilities or claims are currently anticipated to be distributed to the Unit Holders in ALP at a later date and may not be distributed until the completion of the liquidation. At such time that ALP considers its liquidation, winding up and termination to be imminent and its net realizable assets to be reasonably determinable, it expects to adopt the liquidation basis of accounting.

Various factors may affect the timing of completing the liquidation, winding up and termination of ALP and the amount of liquidating distributions of funds, if any, out of those retained in reserve. These factors include the time and expense to resolve all obligations, liabilities and claims, including contingent liabilities and claims that are not yet asserted but may be made in the future. Among other things, delays in resolving pending or threatened litigation or other asserted claims, currently unasserted claims that arise in the future and other factors could result in a reduction in future distributions to Unit Holders in ALP and could extend the time, and significantly increase the cost, to complete the liquidation, winding up and termination of ALP. While ALP intends to defend against asserted claims where appropriate, it is currently not possible to identify or assess any defenses or counterclaims that may be available to ALP, or the magnitude of any claims that may be asserted.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported or disclosed in the financial statements and accompanying notes. Significant estimates include the ultimate outcome of contingencies. Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents may consist of U.S. Government obligations with original maturities of three months or less, money market demand accounts and repurchase agreements, the cost of which approximates market value. ALP maintains funds in financial institutions that exceed the FDIC insured limit. ALP does not believe it is exposed to any significant credit risk.

Liabilities and Professional Services

Accounts payable and accrued expenses primarily include professional services, legal fees, and expected litigation settlements. The liability also includes real estate taxes, and other miscellaneous accruals. ALP accrues liabilities when costs are incurred and such costs can be reasonably estimated.

Indemnification of Certain Persons

Under certain circumstances, ALP indemnifies the Administrator and certain other persons performing services on behalf of ALP for liability they may incur arising out of the indemnified persons' activities conducted on behalf of ALP. There is no limitation on the maximum potential payments under these indemnification obligations, and, due to the number and variety of events and circumstances under which these indemnification obligations could arise, ALP is not able to estimate such maximum potential payments. However, historically ALP has not made payments in material amounts under such indemnification obligations, and no amount has been accrued in the accompanying financial statements for these indemnification obligations of ALP.
