Shares of CA Inc. (CA) were falling by 8.37% to $31.75 on Thursday afternoon, following a Wall Street Journal report that that private equity owned business software company BMC Software has ceased merger talks with the tech company.

The ending of deal talks shows that banks are still reluctant to finance leveraged buyouts of mature tech companies at high valuations.

CA makes products that are used in online applications and for mobile tech. Bloomberg first reported a possible merger with BMC last month.
