A company operating in multiple high-inflation countries must adjust its expatriate compensation system to retain assignees. What is the MOST appropriate compensation mechanism to apply?

The home-country balance sheet approach is designed to maintain the expatriate's standard of living and purchasing power equivalent to that of their home country. In high-inflation environments, this method protects assignees from the rapid erosion of local currency value. Adding a guaranteed minimum Cost of Living Allowance (COLA) provides an additional layer of security, ensuring that even if the home country's inflation is low, the assignee's compensation is adjusted to cope with the host country's severe inflation, which is critical for retention.

A. A host-country balance sheet would expose the expatriate directly to the high inflation and currency volatility the company is trying to mitigate, defeating the purpose of a supportive compensation package.
C. Localization ties compensation to volatile local market rates. One-time bonuses are reactive and insufficient to address continuous, high inflation, making financial planning difficult for the assignee.
D. A "global compensation ratio" is not a standard industry term and is too vague. It fails to specify how it would protect an individual assignee from specific, localized hyperinflation.
