Here are five things you must know for Monday, Oct. 24:

1. -- AT&T (T) - Get AT&T Inc. Report agreed to buy Time Warner (TWX) in an ambitious $85.4 billion deal that would create a powerhouse in global telecommunications, television and film. The agreement was approved by the boards of both AT&T and Time Warner.

The deal, which would be half in cash and half in stock, values Time Warner at $107 a share, a 20% premium to its $89.48 closing price on Friday. Time Warner shareholders will receive $53.75 a share in cash and $53.75 a share in AT&T stock. The total transaction value is $108.7 billion, including Time Warner's net debt.

Time Warner shares were fairly flat in premarket trading on Monday, while AT&T shares declined 2.1%.

TheStreet's chief investment strategist, Jack Mohr, said AT&T is paying way too much for Time Warner.

Mohr, who co-manages Action Alerts PLUS with Jim Cramer as a charitable trust, said the merger's nearly $110 billion in total consideration is "staggering on so many financial levels" and "reeks of strategic desperation and financial destruction."

Mohr noted that the deal comes at a time when AT&T is still digesting its recent $50 billion mega-takeover of DirecTV. AT&T also had a disappointing earnings report and a 15% share decline. He added that there's a risk that Time Warner's earnings are arguably "approaching peak levels, which makes the deal that much sweeter for TWX shareholders and that much scarier for anyone invested in AT&T."

The acquisition could win U.S. regulatory approval, but would likely face heavy conditions from the Justice Department and the Federal Communications Commission, according to regulatory observers in Washington.

2. -- Rockwell Collins (COL)  moved to increase its exposure to the commercial aircraft cabin, agreeing to acquire B/E Aerospace (BEAV)  in a deal valued at $8.3 billion including debt.

Terms of the deal call for Cedar Rapids, Iowa-based Rockwell Collins to pay $34.10 in cash and stock worth $27.90 apiece for a total consideration of $62 a share in cash and stock for B/E. The deal values B/E's equity at about $6.4 billion, with Rockwell Collins also set to assume $1.9 billion in net debt.

B/E is a maker of aircraft seats and other interior items, including galleys, lighting systems and modular lavatories. The company has long been a subject of takeover speculation, having weathered an activist campaign earlier in the decade that resulted in the spinning off of its KLX Aerospace distribution business as an independent.

B/E Aerospace shares jumped 18.5% in premarket trading to $59.99.

Genworth shares closed Friday at $5.21.

5. -- TD Ameritrade (AMTD) - Get TD Ameritrade Holding Corporation Report reached a deal to buy online brokerage Scottrade Financial Services for $4 billion in cash and stock.

"The transaction combines two highly complementary organizations with long histories of helping millions of people invest in their financial futures," Ameritrade said in a statement on its website. "For TD Ameritrade, the transaction adds significant scale to its retail business, extends its leadership in trading, and more than triples the size of its geographic sales force footprint."

The cash-and-stock deal is worth $4 billion. TD Ameritrade said it expects $450 million in annual synergies from the deal, plus $300 million in long-term cost savings.

In premarket trading, TD Ameritrade stock was sinking by 1% to $36.70.
