"ECB borrows $1,000,000 USDs by issuing 5-year bonds. ECB's cost of debt is 4%, so it will need to pay $40,000 USDs in interest each year for the next 5 years, and then repay the principal $1,000,000 USD in year 5. ECB's marginal tax rate will remain 35% throughout this period. By how much (in USDs) does the interest tax shield increase the value of ECB? Note: Express your answers in strictly numerical terms. For example, if the answer is $500, enter 500 as an answer."
