Past performance is not a guarantee of future results. Barron's Fund Family Rankings are calculated without the impact of expenses such as 12b-1 fees, front-end loads or sales charges, which would reduce returns. Source: Barron's, 2/14/2020.

To be included in the ranking, a firm must have at least three funds in the general equity category, one world equity, one mixed equity (such as a balanced or target-date fund), two taxable bond funds, and one national tax-exempt bond fund.

Each fund's performance is measured against all of the other funds in its Lipper category, with a percentile ranking of 100 being the highest and one the lowest. This result is then weighted by asset size, relative to the fund family's other assets in its general classification. If a family's biggest funds do well, that boosts its overall ranking; poor performance in its biggest funds hurts a firm's ranking.

Finally, the score is multiplied by the weighting of its general classification, as determined by the entire Lipper universe of funds. The category weightings for the one-year results in 2019 were general equity, 35.4%; mixed asset, 21.1%; world equity, 17%; taxable bond, 21.8%; and tax-exempt bond, 4.6%.
