A financial analyst is evaluating the historical performance of two commodity investment funds, both of which use the Reuters/Jefferies-CRB Index as their benchmark. The analyst has compiled monthly return data and has decided to use the information ratio (iR) to assess which fund has delivered higher returns more efficiently. The relevant data is summarized in the table below:

Metrics	Fund 1	Fund 2	Benchmark
Average monthly return	1.488%	1.468%	1.415%
Average excess return	0.073%	0.053%	0.000%
Standard deviation	0.294%	0.237%	0.238%
Tracking error	0.344%	0.341%	0.000%

Calculate the information ratio for both funds and interpret the results.
