SFE is run by chief executive Owen Kelly with Sir Ewan Brown, of Noble Grossart, as its chairman. Other board members include Tesco Bank's chief executive Benny Higgins, Aegon UK's chief financial officer Clare Bousfield and RBS's Scottish corporate banking boss Ken Barclay.
The SFE accounts show director's remuneration fell from £162,082 to £156,322.
Mr Kelly said: "It has been a busy and productive year for SFE with a diverse series of member events and regular engagement with governments, officials, politicians and the media, over the implications of independence for the financial services industry."
"The role of SFE is to provide a service to members, with the continued growth in our membership and the revenue this creates, we have the opportunity to continue to reinvest our modest profits into that service."
