Final answer:
To determine the total long-term debt of Boston Scientific, including current maturities, one needs to consult the company's 2018 annual report or SEC filings as the necessary information cannot be provided without these documents.
Step-by-step explanation:
To ascertain the total amount of Boston Scientific's long-term debt as of December 31, 2018, including the current maturities, one would need to refer to the company's financial statements, specifically the balance sheet, which is part of the annual report published by Boston Scientific for the year ending on that date.
This information can typically be found in a section labelled 'Long-Term Debt' or a similar designation and would include both the portion of debt maturing within a year (current maturities) and the portion maturing beyond one year (long-term debt).
Unfortunately, without direct reference to Boston Scientific's financial disclosures or annual report for the year 2018, it is not possible to provide a precise figure for their long-term debt.
You would need to access the company's 2018 annual report or 10-K filing with the Securities and Exchange Commission (SEC) to find the exact numbers.
