(1) For Available-for-sale securities, fair value is the assets carrying value, equal to the amortized cost plus any unrealized gains/losses. For Held-to-maturity securities, the amortized cost is the assets carrying value (since there are no other-than-temporary impairments) and the fair value gains/losses are not only unrealized, but also unrecorded.
The money market fund is a daily-traded cash equivalent with price of $1.00, making it a Level 1 asset class, and its carrying cost closely approximates fair value. As the demand deposit (cash) balances vary with the timing of collections and payments, the money market fund can cover any surplus or deficit, and thus is considered Available-for-sale.
The short term investments purchased in November 2010 were comprised of California revenue anticipation notes, which matured in June 2011. In previous periods, these were recorded at their carrying cost as Held-to-maturity as we had both the ability and intent to keep these investments until they mature. The notes were considered a Level 2 asset class, because their pricing is drawn from multiple market-related inputs, but in general not from same-day, same-security trades.
The short term investments purchased in September 2011 are comprised of California revenue anticipation notes, which mature in June 2012. As this is the initial investment in a broader portfolio strategy for yield management, these are considered Available-for-sale. The notes are considered a Level 2 asset class, because their pricing is drawn from multiple market-related inputs, but in general not from same-day, same-security trades.

Current assets and current liabilities are recorded at amortized cost, which approximates fair value due to the short maturities implied.
