Broadcom Corp. on Tuesday boosted its dividend, raised the low end of its projection for fourth-quarter revenue and unveiled changes to its compensation plan as part of a move to enhance its corporate governance.

Chip maker Broadcom is well known in the handheld-device market, as it makes chips for about half the world's tablets and smartphones, but the company has also sought to expand its share of the network-processor market.

The company raised the low end of its revenue forecast by $75 million, putting the range at $2.075 billion to $2.15 billion. It also raised its quarterly dividend by two cents to 14 cents a share, a 17% jump, and authorized $1 billion to buy back shares in 2015. The company's market value is about $23 billion.

Meanwhile, the Silicon Valley company, which previously reviewed its executive pay every three years, said it would begin an annual say-on-pay vote next year. Broadcom also intends to shift its compensation to emphasize performance-based equity.

Among its recent restructuring moves, Broadcom said in July that about 2,500 employees would lose their jobs as it unveiled plans to wind down its operation that made baseband chips for mobile devices. The cuts represented about 20% of its head count.

Shares inched up to $43 in recent after-hours trading. Through Tuesday's closing, the company's stock was up 44% for the year. It set a 52-week-high of $44.33 on Monday.
