With the first half of the year now behind us and better forward visibility, we're refining our financial guidance for the balance of the year.

By segment, at constant currency ex COVID, our full year guidance remains the same and it's unchanged versus what we gave you back in February, which is to say TAS will grow this year around 5% and R and D in the 7% range.
