The numbers: Fiscal third-quarter net income dropped 31% to $50 million and earnings per share fell 34% to 68 cents, hurt by a higher share count. Revenue declined 7% to $2 billion. Its gross margin rose from 18% to 29% and its operating margin climbed from 3% to 8%. A quick ratio of 1.2 demonstrates adequate liquidity. A debt-to-equity ratio of 0.5 is below the industry average, indicating restrained leverage.

The model upgraded BP Prudhoe Bay Royalty Trust ( BPT), a trust with royalty interests in Alaskan oil fields, to "buy."

The numbers: Second-quarter net income fell 63% to $21 million, or 99 cents a share. Revenue declined a comparable amount. The trust's gross margin remained steady at 100% and its operating margin was little-changed at 99%. The trust holds no debt and $1 million of cash reserves, amounting to a quick ratio of 5.3.
