Answer: open to less error in estimation.

## Explanation **FFO (Funds from Operations)** is considered **open to less error in estimation** compared to AFFO (Adjusted Funds from Operations) because: - **FFO** is calculated using standardized accounting principles with fewer adjustments - **AFFO** requires additional estimates and assumptions for: - Maintenance capital expenditures - Straight-line rent adjustments - Lease incentives - Other non-cash items These additional adjustments in AFFO introduce more subjectivity and potential estimation errors, making FFO a more standardized and less error-prone measure. **Why other options are incorrect:** - **B**: AFFO is generally considered a superior measure of economic income as it accounts for capital expenditures needed to maintain property quality - **C**: AFFO is more reflective of a REIT's dividend-paying ability since it considers the cash required for property maintenance Therefore, FFO's main advantage over AFFO is its reduced susceptibility to estimation errors due to fewer subjective adjustments.
