The US dollar has depreciated to its lowest level since June 2018. Over the past several months, the dollar has been losing values against other main currencies. (See the exchange rate between the US dollar and the euro here, for example). If the trend continues, briefly discuss the likely impact (good vs bad) on:

a. Company A: a US firm importing products from overseas.

b. Company B: a US firm exporting products to the overseas markets.

c. Company C: a Japanese firm exporting products to the US market (assuming the dollar depreciates agains the yen)
