A breakdown of costs and revenues showed that the Italian incurred total expenses of €79,000 (£70,000/$92,000) for the financial year ending March 31, 2016.

A budget for the following 12 months forecast this to increase to €140,000 (£123,000/$163,000) but, in the end, a total of €180,585 (£159,029/$210,268) was spent - an increase of 128 per cent on the previous year. 

This included travelling expenses of €57,799 (£50,896/$67,296), "other" costs of €101,395 (£89,290/$118,055) and a new figure of €21,401 (£18,846/$24,919) for a car. 

There are currently no accounts available for the most recent financial year, including this year's Winter Olympics in Pyeongchang.

Ferriani is locked in a two-horse race with Switzerland's Fritz Burkard at a Congress in Rome tomorrow to serve another term in the top position after first being elected in 2010.

His spending dwarfs his colleagues on the IBSF Executive Committee. 

This was revealed in documents, obtained by insidethegames and distributed to the IBSF membership before the Congress week.

An explanation for the high expenses has still to be given by Ferriani after he was contacted by insidethegames today.

It is understood, though, that delegates at today's pre-Congress meeting in the Italian capital were told that the rise was due to his enhanced responsibilities in the International Olympic Committee (IOC) and wider sports world. 

Direct travelling for the IOC should be covered by their own expenses system, however.

An IBSF balance sheet - which does not appear to have been audited externally - revealed that income of just €276,509 (£243,490/$321,956) was generated for the year ending March 31, 2017.

A net loss of €4.244 million (£3.7370 million/$4.941 million) for the year was also recorded, along with retained earnings of €9.192 million (£8.094 million/$10.702 million).

This shows that, like many of the smaller sporting governing bodies, the IBSF are dependent on a quadrennial payment from the IOC designed to sustain the body for a four-year period culminating in the Olympic Games.

The separate costs and revenues document does, however, refer to €1 million (£880/$1.1 million) revenue in sponsorship for 2016 and 2017 as well as €289,800 (£255,231/$337,477) received in television rights.

It is not clear where exactly the sponsorship revenue came from, although it is likely to include marketing partner Infront and Russian gas giant sponsor Gazprom.

It is also not clear why these figures are not included on the balance sheet.

Ferriani, an IOC member and close ally of its President Thomas Bach, is facing criticism over a failure to realise pledges towards transparency and accountability during his eight years in office.

It comes amid wider concern over the governance of winter sports following the removal of the International Biathlon Union President Anders Besseberg and secretary general Nicole Resch earlier this year as they contest allegations of bribery. 

The 58-year-old Ferriani is considered the favourite in the Presidential election tomorrow and is thought to enjoy the support of large countries such as Germany.

His opponent Burkard's best chance appears to be picking off support from smaller countries. 

insidethegames has been told that Monaco's IOC member Prince Albert delivered a speech backing Ferriani - thus indicating the Olympic Movement's preference - during the pre-Congress today.
