Newcastle have revealed a loss of £17.1million as a result of their relegation from the Barclays Premier League.
However, the drastic action the Magpies took to address their financial situation in the face of a reduction in turnover of 39% - from £86.1million during the year covering the 2008-09 season to £52.4million - means their losses increased only slightly from £15.2million.
But the annual accounts for the year ending June 30, 2010, which were submitted to Companies House today, also show that owner Mike Ashley had to inject a further £42million into the club despite an increase in gate receipts as more than a million fans attended games at St James' Park.
The latest figures do not reflect Newcastle's return to the top flight at the end of last season, with promotion worth anything up to £60million to successful clubs, nor Andy Carroll's £35million departure to Liverpool in January.
Managing director Derek Llambias said: "Our overriding aim in 2009-10 was to secure promotion back to the Premier League at the first attempt.
"Relegation presented a considerable challenge for us financially.
"With such a marked reduction in turnover, largely due to reduced TV and media revenue, we needed to cut our operating costs accordingly without jeopardising our ability to return to top flight football straight away.
"We succeeded in reducing our wage bill considerably whilst maintaining the basis of a Premier League squad.
"It has been a significant achievement to keep our overall loss at a level similar to the year before despite the impact of relegation, and our ability to do this has been helped immeasurably by the continued financial support of Mike Ashley, who injected a further £42million into the club last year interest-free."
The club made an operating loss of £33.5million compared to £37.7million the previous year, but that was reduced to £17.1million by player trading.
Obafemi Martins, Sebastien Bassong, Damien Duff, Habib Beye and Geremi were among those to depart as the Magpies attempted to slash expenditure.
However, revenue from television and other media fell 57% from £37.6million to £16million, although new sponsorship deals were struck with Puma and Northern Rock.
That prompted the club's hierarchy to trim operating costs from £98million to £74.4million, a reduction of 24%.
But their determination to retain the services of enough Premier League-class players to launch a credible bid for promotion meant the wage bill still amounted £47.5million despite a 33% drop from £71.1million.
As a result, the wages-to-turnover ratio increased to a staggering 90.6% from 82.6% earlier. The recommended level is 50%.
The club's overall debt burden remained stable at £150million, although bank borrowings fell by £25million and were replaced by a loan of the same amount from Ashley, taking the total he has loaned the club to £139.8million, all of it interest-free.
Ashley, who also advanced £13million to cover the acquisition of January signings Danny Simpson, Mike Williams, Wayne Routledge and Leon Best, has enjoyed an uneasy relationship with large sections of the fans for much of his time at the helm.
But that did not prevent Newcastle from recording an average home crowd during the reporting period of 43,388, the fourth highest in the country.
