Jan 11 (Reuters) - Carnival Corp reported a preliminary adjusted net loss of $1.9 billion for the fourth quarter on Monday, as the cruise operator's business was brought to a virtual standstill by the COVID-19 pandemic.

The company said it ended the fiscal year with $9.5 billion in cash and has the liquidity to sustain itself through 2021, even in a zero-revenue environment.
