Discovery Communications chief executive David M. Zaslav, who received the second-highest cash compensation of a Washington area public company chief executive in 2012, has a new contract that will carry him through Dec. 31, 2019.

Zaslav will continue to receive a base salary of $3 million a year through the end of 2019. The contract includes a target bonus of $6.6 million this year, which is 220 percent of salary.

The bonus isn’t guaranteed. The amount will depend on achieving certain performance goals.

So far, Zaslav has performed. Under his leadership, the market capitalization of Discovery Communications has increased to $30 billion from $6 billion .

Zaslav also received stock grants and options potentially worth tens of millions of dollars over the life of the contract, which makes him a significant shareholder with a stake in Discovery’s success. In all, those grants could exceed $100 million in value, according to Aaron Boyd, director of governance research at Equilar, a firm that analyzes executive compensation.

The new agreement includes allowances for automobiles and use of the company’s aircraft.

Carlyle Watch:

Three Washingtonians grabbed the brass ring – a Carlyle Group partnership. Mark Johnson, 40, David Daniel, 46, and Alok Gaur, 45, were named partners at the private equity giant last week. They join more than 113 people with that title at the 1,450-person global investment firm. This is the first time Carlyle has publicly announced new partners, a result of becoming a public company, according to a spokesman.

Johnson is in the U.S. Buyout fund, where he specializes in telecommunications and media investments. Daniel is focused on buying and selling real estate in the United States. Gaur helps raise the money the firm invests from wealthy individuals and pension funds. Carlyle won’t say what a partnership is worth, but the Buzz hears that each partner’s reward could top a couple of million in stock over time. Brass ring? Make that gold.

The price of history

The auction of a Thomas Jefferson hand-drawn survey sold for $34,500 to an unnamed buyer last month at Falls Church-based Quinn’s Auction Galleries’ Charlottesville arm, known as Quinn & Farmer Auction Group.

The amount was nearly triple the $12,000 that the item was expected to bring.

The survey map, dating from 1800, had been discovered by two Quinn & Farmer associates at the Brandon Plantation, a National Historic Landmark south of Richmond.

Emilia Lanwehr and Skip Usry were supervising the removal of personal property from Brandon, a working agricultural plantation south of Richmond. One particular piece stood out: a survey of a 1,334-acre farm near Monticello that appeared to be hand-drawn by Thomas Jefferson himself. Usry, according to a spokesman for the auction house, nudged Lanwerh and asked. “Do you think it could be real?”

The Buzz hears:

The weather outside was beyond freezing last week when Terry D. McCallister, an assistant secretary at the Greater Washington Board of Trade, took time out from some introductions to make an observation about the toasty temperatures inside. “Sometimes you just have to raise your hands in the sky and say ‘Thank God for the gas company.’” McCallister’s day job? Chairman and chief executive of Washington Gas Light Co.

District-based Eyebloc was scheduled to be featured on ABC’s “Shark Tank.” Eyebloc is a cover placed over Webcams of laptops and tablets so hackers can’t spy on the owners. Eyebloc president C.J. Isakow started an Indigogo crowdfunding campaign with an initial goal of raising $5,000. The company, headquartered at DC’s 1776 , printed a 3D prototype at the D.C. public library.

Local investor Raul Fernandez and a bunch of fellow Washington businessmen were in Las Vegas last week scouting the latest technology advances at CES, the gigantic consumer electronics trade show.

Fernandez was at CES with Neil D. Cohen, president of District Photo (and a partner with Fernandez in Monumental Sports & Entertainment), Washington entrepreneur Mark Ein and two former Federal Communications Commission chairmen: Michael Powell, current president of the National Cable & Telecommunications Association, and Julius Genachowski, who joined the Carlyle Group last week.

“The most interesting things were the 3-D printers,” Fernandez said. “Last year, there were half a dozen companies. This year, a whole wing of the hall dedicated to 3-D printers.

“The other cool thing is the Flir, a thermal imager that you stick on the iPhone and it turns the phone into a thermal camera that allows you to look at a heat signature ... These types of cameras used to cost tens of thousands of dollars, and now it’s an add-on to an iPhone.”

Fernandez’s company, surveillance firm ObjectVideo, did a recent deal with Flir.

Factoid of the week:

5.2M That’s the amount of tons of crushed stone produced last year by Richmond-based Luck Stone, which has four quarries in Northern Virginia. The demand in Northern Virginia declined from 2005 to 2009, and has slowly increased from 2009 to present. “The healthier economy and a pickup in residential construction is driving the increase,” Luck Stone president Bob Grauer said.
