2014 Acquisitions Interventional Business of Bayer AG On August 29, 2014, we completed the acquisition of the Interventional Division of Bayer AG (Bayer), for a total cash consideration of $414 million.
We believe that this acquisition enhances our ability to offer physicians and healthcare systems a more complete portfolio of solutions to treat challenging vascular conditions.
The transaction includes the AngioJet?
Thrombectomy System and the Fetch?2 Aspiration Catheter, which are used in endovascular procedures to remove blood clots from blocked arteries and veins, and the JetStream?
Atherectomy System, used to remove plaque and thrombi from diseased arteries.

IoGyn, Inc.  On May 7, 2014, we completed the acquisition of the remaining fully diluted equity of IoGyn, Inc.  (IoGyn).
Prior to the acquisition, we held a 28 percent minority interest in IoGyn in addition to notes receivable of approximately $8 million.
Total consideration was comprised of a net cash payment of $65 million at closing to acquire the remaining 72 percent of IoGyn equity and repay outstanding debt.
IoGyn has developed the Symphion?
System, a next generation system for hysteroscopic intrauterine tissue removal including fibroids (myomas) and polyps.
In March 2014, IoGyn received U. S.  Food & Drug Administration (FDA) approval for the system and in October 2014, we began a limited market release of the system in the United States.
We integrated the operations of the IoGyn business into our Urology and Pelvic Health business.
In addition, we completed other acquisitions during 2014 for total consideration of $7 million cash at closing plus contingent consideration of up to $4 million.

We re-measured our previously-held investments to their estimated acquisition-date fair value of $31 million and recorded a gain of $19 million in other, net, in the accompanying consolidated statements of operations during the second quarter of 2014.
We measured the fair values of the previously-held investments based on the liquidation preferences and priority of the equity interest and debt, including accrued interest.
the company granted 1,020 performance shares.
The vesting of these shares is contingent on meeting stated goals over a performance period.
Beginning with restricted stock grants in September 2010, dividends are accrued on restricted Class A common stock and restricted stock units and are paid once the restricted stock vests.
The following table summarizes restricted stock and performance shares activity for 2010:
## Table 4 ##
The total fair value of restricted stock that vested during the years ended December 31, 2010, 2009 and 2008, was $10.3 million, $6.2 million and $2.5 million, respectively.
Eligible employees may acquire shares of CME Group’s Class A common stock using after-tax payroll deductions made during consecutive offering periods of approximately six months in duration.
Shares are purchased at the end of each offering period at a price of 90% of the closing price of the Class A common stock as reported on the NASDAQ.
Compensation expense is recognized on the dates of purchase for the discount from the closing price.
In 2010, 2009 and 2008, a total of 4,371, 4,402 and 5,600 shares, respectively, of Class A common stock were issued to participating employees.
These shares are subject to a six-month holding period.
Annual expense of $0.1 million for the purchase discount was recognized in 2010, 2009 and 2008, respectively.
Non-executive directors receive an annual award of Class A common stock with a value equal to $75,000.
Non-executive directors may also elect to receive some or all of the cash portion of their annual stipend, up to $25,000, in shares of stock based on the closing price at the date of distribution.
As a result, 7,470, 11,674 and 5,509 shares of Class A common stock were issued to non-executive directors during 2010, 2009 and 2008, respectively.
These shares are not subject to any vesting restrictions.

The company charges all customers in its service area for the delivery of electricity.
O&R generally recovers, on a current basis, the cost of the electricity that it buys and then sells to its full-service customers.
It does not make any margin or profit on the electricity it sells.
O&R’s New York electric revenues (which accounted for 76 percent of O&R’s electric revenues in 2018) are subject to a revenue decoupling mechanism.
As a result, O&R’s New York electric delivery revenues are generally not affected by changes in delivery volumes from levels assumed when rates were approved.
O&R’s electric sales in New Jersey are not subject to a decoupling mechanism.
O&R’s electric sales and deliveries for the last five years were:
## Table 5 ##
For further discussion of the company’s electric operating revenues and its electric results, see “Results of Operations” in Item 7.
For additional segment information, see Note N to the financial statements in Item 8.
Electric Peak Demand The electric peak demand in O&R’s service area occurs during the summer air conditioning season.
The weather during the summer of 2018 was cooler than design conditions.
O&R’s 2018 service area peak demand was 1,470 MW, which occurred on July 2, 2018.
“Design weather” for the electric system is a standard to which the actual peak demand is adjusted for evaluation and planning purposes.
Since the NYISO can invoke demand reduction programs under specific circumstances, design conditions do not include these programs’ potential impact.
However, the O&R forecasted peak demand at design conditions does include the impact of certain demand reduction programs.
The company estimates that, under design weather conditions, the 2019 service area peak demand will be 1,585 MW.
The company forecasts an average annual decrease in electric peak demand in its service area at design conditions over the next five years to be approximately 0.3 percent.
Electric Supply The electricity O&R sold to its full-service customers in 2018 was purchased under firm power contracts or through the wholesale electricity market.
The company expects that these resources will again be adequate to meet the requirements of its customers in 2019.
O&R does not own any electric generating capacity.
The company plans to meet its continuing obligation to supply electricity to its customers through a combination of electricity purchased under contracts or purchased through the wholesale electricity market.
To reduce the volatility of its customers’ electric energy costs, the company has contracts to purchase electric energy and enters into derivative transactions to hedge the costs of a portion of its expected purchases.
For information about the company’s contracts, see Note O to the financial statements in Item 8.
In general, the Utilities recover their costs of purchasing power for full service customers, including the cost of hedging purchase prices, pursuant to rate provisions approved by the state public utility regulatory authority having jurisdiction.
See “Financial and Commodity Market Risks – Commodity Price Risk,” in Item 7 and “Recoverable Energy Costs” in Note A to the financial statements in Item 8.
From time to time, certain parties have petitioned the NYSPSC to review these provisions, the elimination of which could have a material adverse effect on the Companies’ financial position, results of operations or liquidity.
Gas Operations Gas Facilities O&R’s capitalized costs for utility plant, net of accumulated depreciation for gas facilities, which are primarily distribution facilities, were $607 million and $573 million at December 31, 2018 and 2017, respectively.
