Smiles returned to the faces of Celtic fans on Sunday when they beat Aberdeen 2-0 to win Scotland's League Cup and lift the CIS Insurance Cup.
This is the first year of CIS's four-year sponsorship of Scotland's League Cup.
A CIS spokesman said the outcome was particularly welcome for Celtic, who had experienced a troubled season.
In English football, CIS is the sponsor of Blackburn Rovers, who were relegated last year from the Premiership to the First Division.
This is the last year of the company's sponsorship. According to the spokesman, it is now 'being reviewed'.
