Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of Toll Brothers, Inc. (the “Company,” “we,” “us,” or “our”), a Delaware corporation, and its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. Investments in 50% or less owned partnerships and affiliates are accounted for using the equity method unless it is determined that we have effective control of the entity, in which case we would consolidate results of operations and financial condition of the entity. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. The October 31, 2015 balance sheet amounts and disclosures included herein have been derived from our October 31, 2015 audited financial statements. Since the accompanying condensed consolidated financial statements do not include all the information and footnotes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements, we suggest that they be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended October 31, 2015 (“2015 Form 10-K”). In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, which are of a normal recurring nature, necessary to present fairly our financial position as of July 31, 2016; the results of our operations for the nine-month and three-month periods ended July 31, 2016 and 2015; and our cash flows for the nine-month periods ended July 31, 2016 and 2015. The results of operations for such interim periods are not necessarily indicative of the results to be expected for the full year. Recent Accounting Pronouncements In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-04, “Receivables—Troubled Debt Restructurings by Creditors” (“ASU 2014-04”), which clarifies when an in substance repossession or foreclosure of residential real estate property collateralizing a consumer mortgage loan has occurred. By doing so, this guidance helps determine when the creditor should derecognize the loan receivable and recognize the real estate property. We adopted ASU 2014-04 on November 1, 2015, and the adoption did not have a material effect on our consolidated financial statements or disclosures. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to estimate credit losses. ASU 2016-13 is effective for our fiscal year beginning November 1, 2020, with early adoption permitted as of November 1, 2019. We are currently evaluating the impact that the adoption of ASU 2016-13 may have on our consolidated financial statements and disclosures. In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes and forfeitures, statutory tax withholding requirements and classification on the statement of cash flows. ASU 2016-09 is effective for our fiscal year beginning November 1, 2017. We are currently evaluating the impact that the adoption of ASU 2016-09 may have on our consolidated financial statements and disclosures. In February 2016, the FASB issued ASU No. 2016-02, “Leases” (“ASU 2016-02”), which requires an entity to recognize assets and liabilities on the balance sheet for the rights and obligations created by leased assets and provide additional disclosures. ASU 2016-02 is effective for our fiscal year beginning November 1, 2019, and, at that time, we will adopt the new standard using a modified retrospective approach. We are currently evaluating the impact that the adoption of ASU 2016-02 may have on our consolidated financial statements and disclosures. In April 2015, the FASB issued ASU No. 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customers’ Accounting for Fees Paid in a Cloud Computing Arrangement” (“ASU 2015-05”). ASU 2015-05 provides guidance for a customer to determine whether a cloud computing arrangement contains a software license or should be accounted for as a service contract. ASU 2015-05 is effective for our fiscal year beginning November 1, 2016, and, at that time, we may adopt the new standard either retrospectively or prospectively. We do not expect the adoption of ASU 2015-05 to have a material effect on our consolidated financial statements or disclosures. In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis” (“ASU 2015-02”), which eliminates the deferral granted to investment companies from applying the variable interest entities (“VIEs”) guidance and makes targeted amendments to the current consolidation guidance. The new guidance applies to all entities involved with limited partnerships or similar entities and will require re-evaluation of these entities under the revised guidance which may change previous consolidation conclusions. ASU 2015-02 is effective for our fiscal year beginning November 1, 2016. Upon adoption of ASU 2015-02, we expect that one unconsolidated joint venture, not previously identified as a VIE, will be determined to be a VIE, which will result in a modification of our current disclosures. However, the adoption of ASU 2015-02 is not expected to have a material effect on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), which provides guidance for revenue recognition. ASU 2014-09 affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets and supersedes the revenue recognition requirements in Accounting Standards Codification (“ASC”) Topic 605, “Revenue Recognition,” and most industry-specific guidance. ASU 2014-09 also supersedes some cost guidance included in ASC Subtopic 605-35, “Revenue Recognition—Construction-Type and Production-Type Contracts.” The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under the current guidance. These judgments and estimates include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each separate performance obligation. In August 2015, the FASB issued ASU 2015-14 “Revenue from Contracts with Customers” (“ASU 2015-14”), which delays the effective date of ASU 2014-09 by one year. ASU 2014-09, as amended by ASU 2015-14, is effective for our fiscal year beginning November 1, 2018, and, at that time, we may adopt the new standard under the full retrospective approach or the modified retrospective approach. We are currently evaluating the method of adoption and the impact that the adoption of ASU 2014-09 may have on our consolidated financial statements and disclosures.
