Final answer:
NASAA would likely consider Option C, a payment of $1,000 covering the next month, as a substantial prepayment of fees because it is a large amount for a short service period.
Step-by-step explanation:
The North American Securities Administrators Association (NASAA) has guidelines for what would be considered a substantial prepayment of fees. In assessing the options provided:
- Option A: $600 covering the entire contract year may not be considered substantial if the amount aligns with the duration of service.
- Option B: $500 covering the next 6 months also may not be substantial depending on the services provided during that timeframe.
- Option C: $1,000 covering the next month is likely considered a substantial prepayment since the amount is high for a very short period, exceeding expectations of regular payments.
- Option D: $600 covering the next calendar quarter may not be seen as substantial if it's in accordance with the service period and expected costs.
Hence, NASAA would most likely consider Option C to be a substantial prepayment because it represents a significant amount of money paid for a relatively short service period.
