Summary of Significant Accounting Policies and Recent Accounting Pronouncements	2. Summary of Significant Accounting Policies and Recent Accounting Pronouncements Basis of Presentation The unaudited interim condensed consolidated financial statements of the Company included herein have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) as found in the Accounting Standards Codification (ASC), Accounting Standards Update (ASU) of the Financial Accounting Standards Board (FASB) and the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted from this report, as is permitted by such rules and regulations. Accordingly, these financial statements should be read in conjunction with the financial statements as of and for the year ended December 31, 2021 and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 17, 2022 (2021 Annual Report on Form 10-K). The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited financial statements, and updated, as necessary, in this report. In the opinion of the Company’s management, the accompanying unaudited interim condensed consolidated financial statements contain all adjustments that are necessary to present fairly the Company’s financial position as of September 30, 2022, the results of its operations for the three and nine months ended September 30, 2022 and 2021, stockholder’s equity for the three and nine months ended September 30, 2022 and 2021 and cash flows for nine months ended September 30, 2022 and 2021. Such adjustments are of a normal and recurring nature. The results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results for the year ending December 31, 2022 or for any future period. The accompanying unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Blueprint Medicines Security Corporation, which is a Massachusetts subsidiary created to buy, sell and hold securities, Blueprint Medicines (Switzerland) GmbH, Blueprint Medicines (Netherlands) B.V., Blueprint Medicines (UK) Ltd, Blueprint Medicines (Germany) GmbH, Blueprint Medicines (Spain) S.L., Blueprint Medicines (France) SAS, and Blueprint Medicines (Italy) S.r.L. Lengo Therapeutics, Inc. (Lengo), which was acquired on December 30, 2021, was dissolved in June 2022. All intercompany transactions and balances have been eliminated. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Management considers many factors in selecting appropriate financial accounting policies and in developing the estimates and assumptions that are used in the preparation of the financial statements. Management must apply significant judgment in this process. Management’s estimation process often may yield a range of potentially reasonable estimates and management must select an amount that falls within that range of reasonable estimates. Estimates are used in the following areas, among others: revenue recognition, inventory, operating lease right-of-use assets, operating lease liabilities, stock-based compensation expense, accrued expenses, liabilities related to the sale of future royalties and future revenues, equity investment, and income taxes. The length of time and full extent to which the ongoing COVID-19 pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition, including revenues, expenses, reserves and allowances, manufacturing and supply, clinical trials, research and development costs and employee-related amounts, will depend on future developments that are highly uncertain, subject to change and difficult to predict, including as a result of new information that may emerge concerning COVID-19, including the identification and spread of new variants, and the actions taken to contain or treat COVID-19, as well as the economic impact thereof on local, regional, national and international customers and markets. The Company considers the impact of COVID-19 while making the estimates within its consolidated financial statements and there may be changes to those estimates in future periods. Actual results may differ from these estimates. The Russian invasion of Ukraine has not had a material impact on the Company’s business, results of operations and financial condition. Significant Accounting Policies The significant accounting policies used in preparation of these condensed consolidated financial statements for the three and nine months ended September 30, 2022 are consistent with those discussed in Note 2 to the consolidated financial statements in the 2021 Annual Report on Form 10-K, with the exception of the below new policies. Equity Investment Investments in non-marketable equity securities of privately-held companies that do not have readily determinable fair values are carried at cost, less any impairments, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Each period the Company assesses relevant transactions to identify observable price changes, and the Company regularly monitors these investments to evaluate whether there is an indication of impairment. The Company evaluates whether an investment’s fair value is less than its carrying value using an estimate of fair value, if such an estimate is available. For periods in which there is no estimate of fair value, the Company evaluates whether an event or change in circumstances has occurred that may have a significant adverse effect on the value of the investment. Liabilities related to the sale of future royalties and revenues The Company accounts for net proceeds from sales of the Company’s rights to receive future royalty payments and from sales of future revenues as liabilities if the Company has significant continuing involvement in the generation of the related future cash flows. Interest on the liabilities related to the sale of future royalties and revenues will be recognized using the effective interest rate method over the life of the related royalty or revenue stream. The liabilities related to the sale of future royalties and revenues and the related interest expenses are based on the Company’s current estimates of future royalties or revenues as well as commercial milestones expected to be achieved and received over the life of the arrangement, which the Company determines by using forecasts of the underlying drug products of the underlying regions. The Company will periodically assess the expected payments and to the extent the amount or timing of the future estimated payments is materially different than previous estimates, the Company will account for any such change by adjusting the carrying value of the liabilities related to the sale of future royalties and revenues, and prospectively recognizing the related interest expenses. New Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that the Company adopts as of the specified effective date. The Company does not believe that the adoption of recently issued standards have or may have a material impact on its condensed consolidated financial statements and disclosures. Fair value measurements In June 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820) – Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. This standard clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. This standard will be effective for the Company on January 1, 2024, and is not expected to have a material impact on the Company’s condensed consolidated financial statements and related disclosures.

The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Significant Accounting Policies

The significant accounting policies used in preparation of these condensed consolidated financial statements for the three and nine months ended September 30, 2022 are consistent with those discussed in Note 2 to the consolidated financial statements in the 2021 Annual Report on Form 10-K, with the exception of the below new policies.

Equity Investment

Investments in non-marketable equity securities of privately-held companies that do not have readily determinable fair values are carried at cost, less any impairments, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Each period the Company assesses relevant transactions to identify observable price changes, and the Company regularly monitors these investments to evaluate whether there is an indication of impairment. The Company evaluates whether an investment’s fair value is less than its carrying value using an estimate of fair value, if such an estimate is available. For periods in which there is no estimate of fair value, the Company evaluates whether an event or change in circumstances has occurred that may have a significant adverse effect on the value of the investment.

Liabilities related to the sale of future royalties and revenues

The Company accounts for net proceeds from sales of the Company’s rights to receive future royalty payments and from sales of future revenues as liabilities if the Company has significant continuing involvement in the generation of the related future cash flows. Interest on the liabilities related to the sale of future royalties and revenues will be recognized using the effective interest rate method over the life of the related royalty or revenue stream. The liabilities related to the sale of future royalties and revenues and the related interest expenses are based on the Company’s current estimates of future royalties or revenues as well as commercial milestones expected to be achieved and received over the life of the arrangement, which the Company determines by using forecasts of the underlying drug products of the underlying regions. The Company will periodically assess the expected payments and to the extent the amount or timing of the future estimated payments is materially different than previous estimates, the Company will account for any such change by adjusting the carrying value of the liabilities related to the sale of future royalties and revenues, and prospectively recognizing the related interest expenses.

New Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that the Company adopts as of the specified effective date. The Company does not believe that the adoption of recently issued standards have or may have a material impact on its condensed consolidated financial statements and disclosures.

Fair value measurements

In June 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820) – Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions.
