Net revenues for the second quarter of 2013 were $1,332.3 million, compared to $1,253.2 million in the second quarter of 2012.

Adjusted property EBITDA (1) was $425.7 million for the second quarter of 2013, a 10.8% increase from $384.1 million in the second quarter of 2012.

Table games results in Macau are segregated into two distinct reporting categories, the VIP segment and the mass market segment.
Table games turnover in the VIP segment was $29.9 billion for the second quarter of 2013, a 1.6% decline from $30.3 billion in the second quarter of 2012. VIP table games win as a percentage of turnover (calculated before commissions) for the quarter was 2.94%, which was within the expected range of 2.7% to 3.0% and higher than the 2.79% experienced in the second quarter of 2012.
Table games win in the mass market segment increased by 8.5% in the second quarter to $217.0 million. Mass market table games win per unit per day increased by 6.5% to $11,671 from $10,963 per table in the second quarter of 2012. Drop in the mass market segment was $626.6 million in the second quarter of 2013, down 6.7% from the June 2012 quarter, while the segment's win percentage of 34.6% was higher than the 29.8% generated in the 2012 quarter. Chips purchased at the casino cage are excluded from table games drop and will increase the expected win percentage. Note that customers purchase mass market gaming chips at either the gaming tables or the casino cage. With the increased purchases at the casino cage, we believe the relevant indicator of volumes in the mass market segment should be table games win.
Slot machine handle of $1.2 billion for the second quarter of 2013 was approximately flat with the prior-year quarter, while slot win declined 8.9% compared to the prior-year period. Win per unit per day was 2.9% lower at $731, compared to $752 in the second quarter of 2012. The average number of slots in the 2013 second quarter declined by 57 machines versus the 2012 period.
During the second quarter of 2013, we began a renovation of the approximately 600 guestrooms in the original Wynn Macau tower, contributing to an approximate 5% reduction in the number of available room-nights compared to the second quarter of 2012. We expect to complete the guestroom renovation by the end of 2013.
We achieved an Average Daily Rate (ADR) of $314 for the second quarter of 2013, 1.0% below the $317 reported in the 2012 quarter. Occupancy at Wynn Macau improved to 95.5% from 90.0% in the prior-year period, and revenue per available room (REVPAR) rose 5.0% to $300 in the 2013 quarter from $286 in last year's second quarter. Gross non-casino revenues increased 3.3% during the quarter to $99.9 million.
We currently have 500 tables (285 VIP tables, 205 mass market tables and 10 poker tables) and 884 slot machines.
Cotai Project in Macau
The Company is constructing a full-scale integrated resort containing a casino, hotel, convention, retail, entertainment and food and beverage offerings on Cotai and currently estimates the project budget to be approximately $4.0 billion. In February 2013, we started pre-foundation work and continue to remain on pace with the construction schedule. Additionally, negotiations for a guaranteed maximum price (GMP) contract for the project construction costs are nearing completion. We expect to open our resort in Cotai in the first half of 2016.
During the second quarter of 2013, we invested approximately $113.3 million in our Cotai project.

Adjusted property EBITDA rose to $135.7 million, up 65.6% from the $81.9 million generated in the comparable period in 2012.

Slot machine handle of $712.6 million was 0.7% above the $707.8 million in the comparable period of 2012 and net slot win was up 10.4% due to higher hold in the 2013 quarter.
Gross non-casino revenues for the quarter were $302.1 million, 3.9% higher than in the second quarter of 2012 due to increases in the hotel, food and beverage, and retail segments, and partially offset by lower entertainment revenues.
Room revenues were up 4.6% to $100.6 million during the quarter, versus $96.2 million in the second quarter of 2012. Average Daily Rate (ADR) was up 5.6% to $268, while occupancy of 86.9% was below the 87.6% experienced in the second quarter of 2012. Revenue per available room (REVPAR) was $233 in the 2013 quarter, 4.7% above the $222 reported in the prior-year quarter.
Food and beverage revenues increased 5.9% to $146.6 million, a result of revenue increases at both the property's restaurants and its nightclubs. Retail revenues were $22.1 million in the quarter, up 5.2% from last year's quarter. Entertainment revenues declined to $14.7 million in the 2013 second quarter from $18.1 million due to a show that ended its run at the Encore Theater in November 2012.
Balance Sheet and Other
Our total cash and investments balance at June 30, 2013 was $2.5 billion. Total debt outstanding at the end of the quarter was $6.0 billion, including $3.3 billion of Wynn Las Vegas debt, $749.4 million of Wynn Macau debt and $1.9 billion at the parent company.
During the quarter ended June 30, 2013, stock-based compensation increased primarily due to the retirement of the Company's former chief operating officer and the related accelerated vesting of shares previously granted to him.
During both the 2013 and 2012 second quarters, the Company recorded adjustments to its reserve estimates for casino accounts receivable based on the results of historical collection patterns and current collection trends. This change was the primary factor that resulted in an $11.2 million and a $17.3 million credit to the provision for doubtful accounts for the second quarters of 2013 and 2012, respectively. The adjustment in the second quarter of 2013 was $14.9 million, consisting of a $12.2 million credit at Wynn Las Vegas and a $2.7 million credit at Wynn Macau.
