6.	Stock-Based Compensation

Our stock-based compensation plans include a Long-Term Incentive Plan (LTIP), an Employee Stock Purchase Plan, and a Restated Stock Option Plan (Restated SOP). The Restated SOP was terminated in the second quarter of 2012. Shareholders approved the amended LTIP and authorized an additional 250,000 shares for the plan. A variety of equity vehicles may be granted under the LTIP. Together these plans are designed to promote stock ownership in NW Natural by employees and officers. For additional information on our stock-based compensation plans, see Note 6 in the 2011 Form 10-K and current updates provided below.

Long-Term Incentive Plan

In the second quarter of 2012, shares available for issuance under the LTIP were increased from 600,000 shares to 850,000 shares. The additional 250,000 shares may only be used for option grants under the LTIP and not for full-value awards such as Restricted Stock Units (RSUs) or performance shares.

Performance-Based Stock Awards. On February 22, 2012, 35,340 performance-based shares were granted under the LTIP, which include a market condition, based on target-level awards and a weighted-average grant date fair value of $53.92 per share. Fair value was estimated as of the date of grant using a Monte-Carlo option pricing model based on the following assumptions:



Stock price on valuation date	$	48.00
Performance term (in years)	3.0
Quarterly dividends paid per share	$	0.445
Expected dividend yield	3.6		%
Dividend discount factor	0.9012

Restricted Stock Units. During the nine months ended September 30, 2012, the company granted 22,220 RSUs under the LTIP with grant date fair values ranging from $48.00 to $48.25 per share. The RSUs awarded include a performance based threshold and a vesting period of four years from the grant date. The Company is obligated upon vesting of an RSU to issue the RSU holder one share of common stock plus a cash payment equal to the total amount of dividends paid per share between the grant date and vesting date of the RSU.

Restated Stock Option Plan

As of September 30, 2012, there was $0.6 million of unrecognized compensation cost from grants of stock options in prior years, which is expected to be recognized over a period extending through 2014. The Restated SOP was terminated in the second quarter of 2012; however, outstanding options may still be exercised through their expiration dates. Any new grants of stock options would be made under the LTIP. No new stock options were granted in the nine months ended September 30, 2012.
