So round down to a number you think is actually reasonable. Less than 1% without any additional information should be treated as being close to 1%. If it were close to 0.5%, they'd have said "about half a percent" or something similar. So it's reasonable to assume that it's close enough to 1% to use 1% as a proxy.Less than 1%.
