Sweden-based security services provider Securitas AB's credit metrics are weak for the 'BBB+' rating, due to a decline in cash flow and an increase in debt in the financial year ended Dec. 31, 2011. Although we forecast some improvement in 2012, we anticipate that the group's credit metrics will remain below our guideline levels for the rating. We are therefore revising our outlook on Securitas to negative from stable and affirming our 'BBB+/A-2' long- and short-term corporate credit ratings on the group. The negative outlook reflects the risk that Securitas' metrics will not improve in line with our forecast, and will remain weak for the 'BBB+' rating.
