Invesco Trimark, an investment management company, has extented its tax-efficient flexible distribution series T-Flex to eight additional funds, bringing the total funds offering the feature to 26, including all five Dialogue Portfolios.

The T-Flex extension will offer investors broad asset category representation that provides the major building blocks of a well-diversified portfolio, the company said.

T-Flex provides investors with the choice of up to three annual target distribution levels of 4%, 6% or 8% to generate a steady tax-efficient monthly cash flow stream from their investment, according to Invesco Trimark. Each T-Flex series is structured to pay out a fixed, monthly distribution that will be reset at the end of each calendar year.
