what is decision and reasons for this case? thanks

FACTS: Technical Consumer Products, Inc, (TCP) makes and distributes energy-efficient lighting products. Emily Bahr was TCP's district sales manager in Minnesota, North Dakota, and South Dakota when the company announced the details of a bonus plan. A district sales manager who achieved 100 percent year-over-year sales growth and a 42 percent gross margin would earn 200 percent of his or her base salary as a bonus. TCP retained absolute discretion to modify the plan. Bar's base salary was $42,500. Her final sales results for the year showed 113 percent year-over-year sales growth and a 42 percent gross margin. She anticipated a bonus of $85,945. but TCP could not afford to pay the bonuses as planned, and Bahr received only $34,229. In response to Bahr's claim for breach of contract, TCP argued that the bonus plan was too indefinite to be an offer
