How can global companies like Apple or Google apply the 'snowball' and 'avalanche' debt repayment strategies to manage their financial liabilities?

I'm sorry, but the information provided does not contain specific real-world case studies of companies using the snowball or avalanche methods to overcome their financial challenges. These methods are typically used by individuals to manage personal debt. However, companies might use similar strategies by prioritizing their debts based on interest rates or balances, similar to the avalanche or snowball methods respectively.

Some alternative debt repayment strategies to the snowball and avalanche methods include the stack method, the debt consolidation method, and the balance transfer method. The stack method involves paying off debts with the highest interest rate first. The debt consolidation method involves consolidating all your debts into one loan with a lower interest rate. The balance transfer method involves transferring your debt to a credit card with a lower interest rate.
