7.	Marketable Securities, Available-for-sale

The Company’s investment portfolio includes mainly municipal debt securities and metropolitan district bond securities, which are included in homebuilding other assets in the accompanying condensed consolidated balance sheets. As defined in ASC Topic

320,

Investments—Debt and Equity Securities

("ASC

320"),

the Company considers its investment portfolio to be available-for-sale. Accordingly, these investments are recorded at their fair values. The cost of securities sold is based on an average-cost basis. Unrealized gains and losses on these investments are included in accumulated other comprehensive income (loss), net of tax, within stockholders' equity. At

March

31,

2017,

accumulated other comprehensive income (loss) included unrealized gains of

$1,000

on available-for-sale marketable securities, offset with reclassification adjustments, which represent net realized earnings associated with the Company’s investment portfolio, which included interest, dividends and net realized gains on sales of marketable securities, and totaled

$173,000

for the

three

months ended

March

31,

2017.

Realized gains or losses were included in homebuilding other income (expense) in the accompanying condensed consolidated statements of operations.

The Company periodically reviews its available-for-sale securities for other-than-temporary declines in fair values that are below their cost bases, as well as whenever events or changes in circumstances indicate that the carrying amount of an asset

may

not be recoverable. At

March

31,

2017,

the Company believes that the cost bases for its available-for-sale securities were recoverable in all material respects.

The primary objectives of the Company’s investment portfolio are safety of principal and liquidity. Investments are made with the purpose of achieving the highest rate of return consistent with these

two

objectives. The Company’s investment policy limits investments to debt securities rated investment grade or better, as well as to bank and money market instruments and to issues by the U.S. government, U.S. government agencies and municipal or other institutions primarily with investment-grade credit ratings. Our policy places restrictions on maturities, as well as on concentration by type and issuer.
