Liverpool are among seven clubs to be investigated by Uefa for possible breaches of Financial Fair Play regulations, European football's governing body has confirmed.
Uefa dictate that clubs participating in European competition's must restrict their financial losses to £35.4m over two seasons.
Liverpool, along with Monaco, AS Roma, Besiktas, Inter Milan, Sporting Lisbon and Krasnodar, have all recently submitted their accounts but have been asked to provide further financial evidence to ensure they have not breached regulation.
Liverpool reported losses of £49.8m for the 2012/13 season and £40.5m for the 10 month period before that.
A statement from Uefa read: "The clubs disclosed a break-even deficit on the basis of their financial reporting periods ending in 2012 and 2013.
"These clubs will need to submit additional monitoring information during October and November upon the deadlines set by the Uefa Club Financial Control Body, subsequent to which, an additional communication shall be made and conservatory measures may be imposed."
Liverpool remain confident they have not fallen foul of Uefa's rules having secured a number of lucrative commercial deals over the past 18 months.
The Reds returned to the Champions League for the first time in five seasons this season and will face no immediate sanctions over the next two months while they submit additional information.
Manager Brendan Rodgers insisted the club are "comfortable" with Uefa's investigation, explaining Liverpool are a firm advocate of the policy.
"It is obviously something that will be dealt with by the directors," Rodgers told reporters during a press conference on Thursday 25 September.
"It is something we are comfortably with because we are advocates of financial fair play. It is ongoing with the club."
Uefa has also announced that five further clubs – Bursaspor, CFR Cluj, Astra Giurgiu, Buducnost Podgorica and Ekranas – will have prize money temporarily withheld while they are investigated for overdue payments to either employees or external parties.
