Atrium will tell investors at its annual meeting that growth is in line with company expectations.
Company chief executive Nick Marsh said despite softening market conditions Atrium's underwriting portfolio continued to "perform well".
Marsh will say today: “The first quarter managing agents' mid-point estimates for the 2003 year of account indicates a small improvement, to a profit of 16.1%.
"For the 2004 year of account we will get the first estimate for the portfolio at the end of the second quarter.
"Although the year of account remains on risk, the underlying incurred loss ratios of the syndicates in which we participate and, where available, the forecast results for the 2004 year, lead us to remain positive about this year of account, despite previously advised losses from the 2004 hurricane season."
He will also outline business plans for its syndicates for 2006. Syndicate 609 will reduce its stamp capacity from £215m to £170m, while Syndicate 570 will lower its capacity from £150m to £125m.
