Thank you, Andrea. Now let's review our fiscal 2023 second quarter financial results. On a total company basis, we generated revenues of $642.2 million and adjusted operating income of $124.1 million, an increase of 24% and 63%, respectively, as compared to the fiscal 2022 second quarter.
As a reminder, the prior year quarter was impacted by the Omicron variant, which resulted in a shortened run of the Christmas Spectacular, a number of canceled and postponed events in our bookings business and a temporary impact to both demand and operations at Tao.
Starting with the Entertainment segment, we generated revenues of $356.5 million and AOI of $66.3 million, both up significantly on a year-over-year basis. These increases were primarily driven by a full run of the Christmas Spectacular, the start of the Knicks and Rangers seasons and continued strength in our bookings calendar. AOI also reflected the impact of expenses related to MSG Sphere as well as costs related to the company's planned spin-off.
We anticipate Sphere costs continuing to increase over the remainder of the fiscal year as we prepare for the planned opening.
Turning to MSG Networks. The segment generated $158.9 million in revenue and $39.3 million in AOI, decreases of 1% and 10%, respectively, as compared to the prior year period. The decrease in AOI primarily reflected lower affiliate revenue and higher rights fees expense as well as higher other programming and production costs. These were partially offset by growth in advertising revenue.
Finally, Tao Group generated $136 million of revenue and $18.7 million of AOI, up 16% and 7%, respectively, as compared to the prior year period. The increase in revenues was driven by higher comparable venue revenues as well as the impact of new openings. AOI results also reflect higher venue level and corporate labor costs as well as higher entertainment costs.
Turning to our balance sheet. As of December 31, we had approximately $554 million of cash on hand and restricted cash and our debt balance was approximately $2.01 billion, reflecting our recent MSG Sphere financing completed at the end of the quarter. Our construction cost estimate for MSG Sphere remains $2.175 billion while project to-date construction costs through December 31 were approximately $2 billion which includes approximately $236 million of accrued costs that were not paid as of December 31 and is net of the $65 million received from the Venetian.
And lastly, with respect to the cost reduction program, which we announced last quarter, and Andrea touched on earlier, we have now completed a strategic review of our businesses and have identified a number of efficiencies across our entertainment and MSG Networks segments. This includes targeted headcount reductions, which have now been implemented and resulted in a restructuring charge of $13.7 million in the fiscal second quarter as well as other nonlabor-related cost savings initiatives.
With that, I will now turn the call back over to Ari.
