After two weeks of legal arguments and testimony the hearing on Kroger's proposed $25-billion takeover of Albertsons is getting closer to wrapping up.

And in a presentation about the merger, the supermarket chain says over the years the company has reduced its gross profit margins to keep prices down. McMullen reiterated the claim in his testimony, noting that Albertsons’ prices are 10% to 12% higher than Kroger’s, so merging will help reduce the disparity.

The chief executives of Kroger and Albertsons are set to testify in federal court about their companies' proposed merger.
