Partially offsetting these positive rating attributes are the current soft market conditions through which Arch, as well as all industry participants, must navigate.

For Arch, factors that could result in negative rating pressure include unfavorable operating profitability trends, outsized catastrophe or investment losses relative to peers, significant adverse loss reserve development and/or a material decline in risk-adjusted capital. However, factors that could lead to a positive outlook or further rating upgrades would be the continuation of long-term, consistently strong operating profitability relative to its peers and maintenance of strong risk-adjusted capital levels.
