In a filing with the U.S. Securities and Exchange Commission on Monday, Carnival said the cruise ship had a net value of $490 million, or 379 million euros, at the end of 2011.
The company's euro-denominated insurance coverage is valued at $510 million, or 395 million euros, according to the filing.
For damage to the ship, Carnival's potential deductible is about $30 million. Insurance for third-party personal injury liability is subject to an additional deductible of about $10 million for the incident.
Carnival self-insures for loss of use of the ship, according to the SEC filing.
Over the weekend, divers found a 17th victim who perished as a result of the January 13 wreck off the coast of Isola del Giglio, Italy.
Carnival said a board committee is hiring outside experts in the fields of emergency response, organization, training and implementation to conduct an audit of the company's emergency response and safety procedures and to conduct a thorough review of the accident.
